The Benefits of Vitamin C for Skin HealthVitamin C, also known as ascorbic acid, plays an essential role in maintaining overall skin health. This potent nutrient offers numerous benefits, making it a staple ingredient in many skincare products. Below, we explore some of the key advantages of incorporating Vitamin C into your skincare routine.
Promotes Collagen ProductionCollagen is a structural protein that maintains the skin's firmness and elasticity. As we age, collagen production declines, leading to signs of aging such as wrinkles and fine lines. Vitamin C is a crucial co-factor in the synthesis of collagen, helping to keep the skin plump and youthful. Regular application of Vitamin C can stimulate collagen production, making the skin look smoother and more resilient.
Accelerates Wound HealingVitamin C's role in collagen production also extends to wound healing. This nutrient supports the repair of damaged skin by promoting new tissue growth. Whether dealing with minor cuts, abrasions, or post-surgical wounds, applying Vitamin C can expedite the healing process and reduce the risk of scarring.
Antioxidant ProtectionEnvironmental factors like pollution and UV radiation generate free radicals, molecules that damage skin cells and accelerate aging. Vitamin C is a powerful antioxidant that neutralizes free radicals, protecting the skin from oxidative stress. By incorporating Vitamin C into your skincare routine, you can shield your skin from environmental damage and maintain a healthier complexion.
Boosts Immune FunctionA robust immune system is vital for overall skin health. Vitamin C bolsters the immune system, making it an essential component of both internal and external treatments. A well-functioning immune system can better fend off skin infections and inflammatory conditions, contributing to clearer, more radiant skin.
Reduces HyperpigmentationHyperpigmentation occurs when certain areas of the skin produce excess melanin, resulting in dark spots or patches. Vitamin C can inhibit melanin production, helping to lighten hyperpigmented areas. Over time, consistent use of Vitamin C can promote a more even skin tone, reducing the appearance of age spots, sun spots, and melasma.
Enhances Skin RadianceOne of the most sought-after benefits of Vitamin C is its ability to enhance skin radiance. By improving skin texture and tone, Vitamin C can give your complexion a noticeable glow. Regular use of Vitamin C serums or creams can help achieve a brighter, more Luminous look.
Prevents SaggingLoss of skin elasticity leads to sagging, which is a common sign of aging. By promoting collagen synthesis and offering antioxidant protection, Vitamin C can help maintain the skin's structural integrity. This results in tighter, firmer skin, reducing the likelihood of sagging.
Combats Environmental DamageExposure to environmental pollutants can wreak havoc on your skin, causing premature aging and damage. Vitamin C acts as a protective barrier, reducing the detrimental effects of pollutants. Adding Vitamin C to your skincare regimen helps combat environmental damage, ensuring your skin remains healthy and vibrant.
Supports HydrationMaintaining adequate moisture levels is crucial for healthy skin. Vitamin C can support skin hydration by enhancing the skin barrier function and reducing water loss. This ensures that your skin stays supple and well-moisturized, reducing the risk of dryness and irritation.
Skin Repair and Protection Against Oxidative StressVitamin C not only protects against oxidative stress but also aids in repairing the skin. By promoting cell regeneration and improving skin texture, Vitamin C helps to rejuvenate and restore damaged skin.

Food Sources of Vitamin CIncorporating Vitamin C into your diet is a great way to boost your skin health from within. Here are some excellent food sources of this essential nutrient:
Including these foods in your diet can help ensure you receive adequate Vitamin C, supporting both your overall health and your skin's vitality.
Convenience of Taking Vitamin C: Supplements vs. Food SourcesWhile both food sources and supplements offer ways to meet your daily Vitamin C needs, supplements provide unmatched convenience. Incorporating Vitamin C-rich foods such as oranges, strawberries, and bell peppers into your diet requires careful meal planning and preparation and adds calories to your diet. In contrast, Vitamin C supplements offer a quick and efficient alternative, allowing you to ensure adequate intake regardless of your dietary habits. This convenience makes supplements particularly appealing for busy individuals or those with specific dietary restrictions, enabling them to maintain optimal Vitamin C levels effortlessly.

Regulating Blood Pressure Naturally
High blood pressure (also known as hypertension) affects about 65 million Americans, or about 1 in 3 adults. There are many potential causes of hypertension, but not necessarily any symptoms. In fact, 30% of the people who have high blood pressure don’t even realize it.
In other words, just because you don’t have symptoms doesn’t mean you don’t have high blood pressure. That’s why it’s called “The Silent Killer.” And, make no mistake about it: high blood pressure is dangerous. It is the number one modifiable cause of stroke. Just lowering blood pressure reduces the chance of stroke by 35 to 40 percent. Other conditions, including heart attack and heart failure can be reduced from 25 to 50 percent, respectively.
In this issue of Ask the Doctor, we’re going to talk about high blood pressure and an exciting natural treatment for lowering blood pressure safely and effectively.
Of course, changing blood pressure numbers depends, in a large part, on the choices we make every day – how much we exercise, the foods we eat, and our lifestyle overall. But, for those times we need extra help, there is a new, scientifically-studied supplement to help us along our path to better health and lower blood pressure.
Blood pressure guidelines from the National Heart, Lung, and Blood Institute.
Q. What exactly is blood pressure?
A. Blood pressure is divided into two parts, systolic and diastolic. Systolic is the pressure of the heart beating. Diastolic is the pressure of the heart and vessels filling. When blood pressure numbers are written out, like “120/80,” 120 is the systolic pressure and 80 is the diastolic pressure. The unit of measurement for blood pressure is millimeters of mercury, written as “mm/Hg.”
Q. What is considered high blood pressure?
A. A person’s blood pressure can naturally vary throughout the day – even between heartbeats.
However, if the numbers are consistently high (over 120 systolic and 80 diastolic), after multiple visits to your healthcare practitioner, you may have either pre-hypertension or high blood pressure.
Young arteries and arteries that are kept young through healthy diet and exercise are typically more elastic and unclogged. Blood flows through them easily and without much effort. However, as we age, our arteries become more prone to plaque buildup (due to diets high in saturated fat and sedentary lifestyles) and don’t “flex” as well under pressure. The result is faster blood flow, all the time. Over the long term, it damages heart tissue, arteries, kidney and other major organs.
To get a better idea of high blood pressure, compare your arteries to a garden hose. When unblocked, a garden hose allows water to flow through it quickly and easily – without any real rush or stress. However, if you block the end of the hose with your thumb, closing it off even a little, water rushes out much more quickly.
For many years, high diastolic pressure was considered even more of a threat than high systolic pressure. That thinking has changed somewhat but high diastolic numbers could still mean organ damage in your body – especially for individuals under 50.
Q. What courses high blood pressure?
A. The reasons for hypertension aren’t always clear. However, there are lifestyle factors that contribute to high blood pressure that you can change:
Body type: Weight isn’t always a reliable indicator of whether or not you’ll have high blood pressure – but the type of weight is. Lean body mass – muscle – doesn’t increase blood pressure levels the way that fat can. However, fat body mass, especially fat around your middle, can contribute to high blood pressure.
Sedentary lifestyle: Too often, many of us sit down all day at work, and then sit down all night at home. Over time, this inactivity usually leads to weight gain, making the heart work harder to pump blood through the body. In a way, it almost seems contradictory, but inactivity usually leads to higher heart rates.
Sodium intake: Sometimes it’s hard to believe how much salt there is in processed foods. However, salt intake in itself is not necessarily bad. For people with a history of congestive heart failure, ischemia, and high blood pressure, sodium is definitely out. For those individuals, it leads to more water retention, which increases blood pressure. (Salt’s effect on water retention is one reason that so many sports drinks have fairly high sodium content – the sodium in the drink prevents your body from sweating out too much water.) But, for healthy individuals, moderate salt intake, especially a mixed mineral salt like sea salt or Celtic salt (good salt should never be white) is fine.
Low potassium intake: Unlike sodium, potassium is a mineral which most Americans get too little of. Potassium helps regulate the amount of sodium in our cells, expelling excess amounts through the kidneys. Low levels of this mineral can allow too much sodium to build up in the body.
Heavy alcohol intake: Having three or more alcoholic drinks a day (two or more for women) nearly doubles an individual’s chance of developing high blood pressure. Over time, heavy drinking puts a lot of stress on the organs, including the heart, liver, pancreas and brain.
Unhealthy eating: Eating a lot of processed or fatty foods contributes to high blood pressure. Adapting a diet that is rich in fruits and vegetables, whole grain products, fish, nuts and magnesium and potassium (like the Dietary Approaches to Stop Hypertension, known as the “DASH” diet) can bring it back down.
Smoking: If you smoke, stop. Smoking damages the heart and arteries – period. Nicotine constricts blood vessels, increases heart rate, and raises blood pressure. This in turn, increases hormone production and adrenaline levels, further stressing the body.
As if that weren’t bad enough, the carbon monoxide in cigarette smoke replaces the oxygen in the blood, making the heart work even harder to make up the difference. Since the effect of a single cigarette can last for an hour, smoking throughout the day leads to continuously revved-up blood pressure.
Some of these factors might sound like a lot to overcome. The important thing to remember is that all of these behaviors are changeable. If you have high blood pressure, modifying any of these can significantly lower blood pressure as part of an overall plan.
Q. What are the blood pressure numbers I should see?
A. Experts consider healthy blood pressure numbers to be 115/75 mm/Hg. The reason? They found that the risk of cardiovascular disease doubles at each increment of 20/10 mmHg over 115/75 mm/Hg. Even small jumps in blood pressure numbers increase the risk of stroke and heart attack.
Q. Okay, so other than diet, exercise and lifestyle changes are there other natural ways or supplements I can use to lower my blood pressure?
A. Yes, in fact, you hear about some of them in the news all the time – fish oil, CoQ10, and garlic. As effective as these symptoms are, they typically lower systolic pressure much more than diastolic pressure.
However, there is a blend of scientifically and clinically studied natural ingredients that lower high blood pressure separately, and work even better when they’re combined. This combination blend contains: dandelion leaf extract, lycopene, stevia extract, olive leaf extract and hawthorn extract.
Every one of these ingredients has been studied and recommended for years. But now, a scientific study on a supplement that combines them in one synergistic formula shows encouraging results for lowering systolic and diastolic blood pressure.
Let’s take a look at each:
Stevia:
Stevia (Stevia rebaudiana) originated in
The leaf of stevia is considered the medicinal part of the plant. Research shows that extracts of the leaf relax arteries and help prevent the buildup of calcium on artery walls – keeping them healthy and reducing blood pressure.
In a long-term, randomized, placebo-controlled clinical study, stevia reduced systolic and diastolic blood pressure. On average, participants’ blood pressure reduced from baseline 150 mm/Hg to 140 mm/Hg systolic and 95 mm/Hg to 89 mm/Hg diastolic.
And, in another double-blind, placebo-controlled clinical study, stevia lowered blood pressure quite significantly – by an average of 14 millimeters of mercury in both systolic and diastolic readings. Those are impressive numbers!
Despite its role as a sweetener, stevia may have a side benefit to for those with hypertension – blood sugar regulation. Scientific studies show that extracts of stevia regulated blood sugar and reduced blood pressure.
A clinical study showed that stevia extract actually improved glucose tolerance by decreasing plasma glucose levels during the test and after overnight fasting in all participants. Regulating blood sugar is very important for those with high blood pressure. When blood sugar levels are high, blood vessels are inflamed. Many people with diabetes have high blood pressure as well. In a paired, cross-over clinical study, stevioside (one of the compounds in stevia) reduced glucose levels in individuals with type 2 diabetes. Further scientific studies show that stevia works to control blood sugar levels by stimulating insulin secretion by the pancreatic beta cells. It shows great potential in treating type 2 diabetes. Further scientific studies show that stevia works to control blood sugar levels by stimulating insulin secretion by the pancreatic beta cells. Its shows great potential in treating type 2 diabetes as well as hypertension.
Hawthorn extract:
Hawthorn (Crataegus spp. Oxycantha) has been used since ancient ties as a medicinal herb – even being mentioned by the Greek herbalist Dioscorides, in the first century AD. Traditionally, it has generally been used for support of the heart. Modern research points to bioflavonoid-like complexes in hawthorn leaf and flower that seem to be most responsible for its benefits on cardiac health, like blood vessel elasticity.
The bioflavonoids found in hawthorn include oligomeric procyanidins, vitexin, quercetin, and hyperoside. They have numerous benefits on the cardiovascular system. Hawthorn can improve coronary artery blood flow and the contractions of the heart muscle. Scientific studies show that the procyanidins in hawthorn are responsible for its ability to make the aorta and other blood vessels more flexible and relaxed, so that blood pumps more slowly and with less effort – sparing the cardiovascular system such a hard workout.
The procyanidins in hawthorn also have antioxidant properties – protecting against free radical cellular damage.
And, hawthorn may also inhibit angiotensin-converting enzyme. Angiotensin-converting enzyme is responsible for retaining sodium and water, and may have roots in our evolutionary development. It influences blood vessel contraction and dilation, sodium and water balance and heart cell development – just about everything that has to do with blood pressure. This may have developed as a way of dealing with periods of drought and stress. By narrowing the blood vessels, the body could guarantee an adequate supply of blood and focus on repairing tissue.
Unfortunately, that can lead to real problems these days. Since many of us live in an industrialized society, and frequently have pretty sedentary lifestyles, conserving sodium just makes the conditions for high blood pressure that much worse.
Like the other ingredients in this combination, hawthorn showed benefits on other body systems, too. In clinical and scientific studies, it not only lowered blood pressure, but also showed anti-anxiety properties and regulated blood sugar.
Olive leaf extract:
Olive leaf (Olea europaea) comes up again and again in scientific and clinical studies as having beneficial effects on hypertension. One of olive leaf’s most beneficial compounds is oleuropein – the same compound that makes olive oil so helpful in reducing blood pressure. Here again, we have to look at the traditional Mediterranean diet, which features voLuminous use of olives and olive oil. Not surprisingly, blood pressure is generally much lower in Greek and Italian populations.
But it’s not just the diet – scientific studies showed that oleuropein lowered blood pressure by relaxing the blood vessels and prevented buildup of plaque in arteries. Plus, whether in olive leaf extract or in olive oil, oleuropein works as an antioxidant, too.
Dandelion leaf extract:
Dandelion (Taraxacum offinale) leaves provide a healthy supply of vitamins, much like spinach. In fact, although it has become the bane of North American gardeners and lawn owners, dandelion greens are a component of many gourmet salads.
Medicinally, dandelion has been used for centuries, dating back to ancient
They are a very rich source of vitamin A, and contain vitamin D, vitamin C, carious B vitamins, iron, silicon, magnesium, zinc and manganese, too. Dandelion leaves produce a diuretic effect in the body, similar to a prescription drug. Since one of dandelion leaf’s traditional uses was the treatment of water retention, it’s really not too surprising. Dandelion leaf is also rich in potassium – one of the vital minerals many Americans lack in their diet. So, even though it may act as a diuretic, it replaces more potassium than the body expels.
The diuretic effect of dandelion can relieve hypertension by drawing excess water and sodium from the body and releasing it through the kidneys as urine. Getting rid of extra water and sodium allows the blood vessels to relax – lowering blood pressure.
Lycopene:
If a nutrient can be called exciting, lycopene is it. Lycopene is found mostly in tomatoes and processed tomato products, like pasta and pizza sauce. Related to beta-carotene lycopene shows great antioxidant abilities among its many talents. In fact, it shows even greater free-radical scavenging properties than beta-carotene, its more famous cousin. Healthy intakes of lycopene can guard against a variety of chronic conditions, including lowering LDL (bad) cholesterol, lowering homocysteine levels and reducing blood platelet stickiness that can lead to clogged arteries. It’s even being studied for its protective effect against prostate cancer.
And, for proof, you don’t have to look too far to see the amazing effect lycopene intake can have on health. The Mediterranean diet provides an excellent example. Its high intakes of vegetables, (tomatoes, of course, playing a central role) fish, and whole grains improve cholesterol levels and lower blood pressure. The research on lycopene as a stand-alone nutrient has been compelling. A randomized clinical trial found that not having enough lycopene was associated with early thickening of the arteries.
So, it makes sense that other clinical trials, showed that higher intakes of lycopene frequently meant less thickening of arteries, and a reduced risk of heart attack. In one study, the risk of heart attack was 60% lower in individuals with the highest levels of lycopene. In a multicenter study, similar results were found – men with the highest levels of lycopene had a 48% lower risk of heart attack.
Q. What can I expect taking this herbal combination?
A. You should notice both systolic and diastolic numbers lowering in about two weeks. The scientific study showed that for pre-hypertensive and stage I, (early hypertensive individuals) this combination for ingredients lowers both systolic and diastolic blood pressure.
When you’re taking herbs to support your blood pressure, it’s important to keep it monitored so you have an accurate reading (and record) of your numbers. If you need to, you can pick up a home blood pressure monitoring device. These can retail for anywhere from $30 all the way up to $200, but buying one in the $30 to $50 range is a good idea and money well spent. Consider taking the machine to your local doctor’s office or fire department to have it tested for accuracy against a professional blood pressure monitor. See the chart below for tips on getting an accurate reading from a home monitor.
Tips for Accurate Blood Pressure Monitoring:
-Relax for about 5 to 10 minutes before measurement.
-If you have just come inside from cold outdoors allow yourself to warm up.
-Remove tight-fitting clothing and jewelry.
-Unless your physician recommends otherwise, use left arm to measure pressure.
-Sit, don’t stand.
-Remain still and do not talk while using the monitor.
Q. Are there any side effects?
A. There were no side effects noted in the study. However, because of the mild diuretic effect of dandelion leaf extract, you may notice an increase in trips to the bathroom. It’s always important to make sure you don’t get dehydrated, so you may want to drink more water during the day.
Conclusion:
High blood pressure doesn’t happen overnight. As we get older, the likelihood of developing hypertension increases. And, stressful, fast-forward lifestyles, bad diets and no exercise conspire to raise our blood pressure.
In my own practice I have helped patients move toward a healthier lifestyle, including diet, exercise, and blood-pressure reducing supplements. They live better, more vibrant lives as a result, and their blood pressure normalizes. It really can happen – you can bring your blood pressure back to normal, and this combination of scientifically and clinically validated ingredients can help.

June 14, 2005 05:23 PM
America's Most Wanted by Brian Amherst Energy Times, January 6, 2000 The United States eats well, a little too well, according to experts. Amply supplied with a large supply of high-calorie food, our diets might seem to be chock full of every conceivable nutrient. Well, to the question "Getting all the right vitamins, minerals and other nutrients?" the most appropriate answer seems to be "Not exactly." Eating a lot doesn't equal eating a lot of the most important vitamins and minerals. So, which vitamins and minerals are likely to show up in short supply in the typical American diet? Calcium certainly sits at the top of list. According to the most recent Continuing Survey of Food Intake by Individuals, which is conducted by the United States Department of Agriculture (USDA), women and girls age 12 and up are not consuming adequate calcium from their diet. Research reveals that about 1200 mg. day suffices for those over age 50 and 1000 mg a day should be adequate if you're between the ages of 19 and 50. Since strong bones are formed during "the first three decades of life," says Laura Bachrach, MD, of Since strong bones are formed during "the first three decades of life," says Laura Bachrach, MD, of Stanford University, ". . .osteoporosis is a pediatric disease." For long-range protection against that bone-weakening disease, kids should eat calcium-rich, low-fat dairy products and plenty of leafy greens (broccoli, cabbage, kale) as well as salmon (with bones), seafood and soy. But the calcium campaign does not end in early adulthood. Bone mass begins to deteriorate at about age 30. Menopausal hormonal changes can exacerbate bone brittleness. Medical conditions, including cancer, liver disease and intestinal disorders; prescription drugs; tobacco and alcohol indulgence; or a decline in activity, especially the weight-bearing kind, also jeopardize bone strength. According to the National Osteoporosis Foundation, about one in every two American women will break a bone after age 50 due to osteoporosis. That translates into about half a million fractured vertebrae and more than 300,000 shattered hips. Frequently, those breaks are life-threatening. Crucial Calcium The critical role of calcium in many body functions is perhaps the most extensively clinically documented among nutrients. Researchers in the Department of Medicine, Oregon Health Sciences University in Portland, reviewed epidemiological and clinical studies conducted over the past two years on the relationship between dietary calcium and blood pressure (J Am Coll Nutr October 1999: 398S-405S). "Nearly 20 years of investigation in this area has culminated in remarkable and compelling agreement in the data," the researchers report, "confirming the need for and benefit of regular consumption of the recommended daily levels of dietary calcium." Investigators at the State University of New York, Buffalo School of Dental Medicine, presented results of their studies of calcium and vitamin C and gum disease at the June 26, 1998 meeting of the International Association for Dental Research. Two separate inquiries revealed that people who consumed too little calcium as young adults, and those with low levels of vitamin C in their diets, appear to have nearly twice the risk of developing periodontal disease later in life than folks with higher dietary levels of either nutrient. Calcium: Much Documented Researchers offer extensive evidence of calcium's benefits on many fronts: n Osteoporosis poses a threat to older men as well as women, according to Randi L. Wolf, PhD, research associate at the University of Pittsburgh Graduate School of Public Health. Dr. Wolf presented her award-winning study to an October 3, 1999 meeting of the American Society for Bone and Mineral Research. Dr. Wolf suggests that men increase their consumption of calcium, particularly after age 80, to avoid age-related declines in the amount of calcium absorbed. According to Dr. Wolf, "It appears that the hormonal form of vitamin D, which is the main regulator of intestinal calcium absorption, may have an important role. We are conducting more research to better understand the reasons for why calcium absorption declines with age in men." n Scientists at Tufts University in Boston did some earlier work on the calcium-vitamin D connection and reported it in the September 4, 1997 New England Journal of Medicine. Using the National Academy of Sciences (NAS) increased recommended daily intake of 1200 milligrams of calcium and 400 to 600 international units of vitamin D for people over 50, the Tufts researchers found that with supplementation of the nutrients, men and women 65 and older lost significantly less body bone and, in some cases, gained bone mineral density. n Two studies published in American Heart Association journals show that atherosclerosis and osteoporosis may be linked by a common problem in the way the body uses calcium. The September 1997 Stroke revealed that, in a group of 30 postmenopausal women 67 to 85 years old, bone mineral density declined as atherosclerotic plaque increased. Researchers reporting in Circulation (September 15, 1997) advanced the theory that the osteoporosis-atherosclerosis connection may be related to a problem in handling calcium. n For people who had colon polyps removed, taking calcium supplements decreased the number of new polyps by 24% and cut the risk of recurrence by 19%, according to researchers at the University of North Carolina, Chapel Hill, School of Medicine. The study, published in the January 14, 1999 New England Journal of Medicine, was a first in crediting calcium with anti-cancer properties. The D Factor Without adequate vitamin D, your absorption of calcium slips and bone loss can accelerate, increasing the risk for fractures. Fifty percent of women with osteoporosis hospitalized for hip fractures at Brigham and Women's Hospital in Boston had a previously undetected vitamin D deficiency (Journal of the American Medical Association, April 28, 1999). University of Pittsburgh Cancer Institute researchers told participants at the April 14, 1997 meeting of the American Association for Cancer Research that vitamin D "significantly inhibits highly metastatic, or widespread, prostate cancer in animals," suggesting its potential for treating men with similar conditions. Few foods that Americans eat, except dairy, contain much vitamin D, but we can usually synthesize sufficient amounts from as few as five minutes' exposure to the sun. But as skin ages, its ability to act as a vitamin D factory decreases. According to Michael F. Holick, the director of the Vitamin D, Skin and Bone Research Laboratory at Boston University Medical Center, upwards of 40% of the adult population over age 50 that he sees in his clinic are deficient in vitamin D. Recently, the National Academy of Sciences (the official body that decrees the required amounts of necessary nutrients) increased the daily recommendations of vitamin D to 600 IU for people over 71, 400 IU for those aged 51 to 70 and 200 IU for people under 50. The best dietary sources, apart from dependable supplements, are dairy and fatty fish like salmon. Four ounces of salmon provide about 300 IU. The Facts About Fats The American lust for low-fat, high-carbohydrate diets filled with sugary foods has exploded into nothing short of "obsession," according to experts at the General Research Center at Stanford University Medical Center (Am J Clin Nutr 70, 1999: 512S-5S). That mania oftens robs us of the crucial balance of omega-3 and omega-6 fatty acids typical of the Mediterranean diet that protect us from heart disease by controlling cholesterol and making blood less likely to form clots. These fatty acids cannot be made by the body but are critical for health: n Omega-3 fatty acid (linolenic acid) comes from fresh, deepwater fish (salmon, mackerel, sardines) and vegetable oils such as canola, flaxseed and walnut. n Omega-6 fatty acid (linoleic acid) found primarily in raw nuts, seeds and legumes and in saturated vegetable oils such as borage, grape seed, primrose, sesame and soybean. The American Heart Association recommends limiting total fat consumption to 30% of daily calories. Saturated fats like those in dairy and meat products as well as vegetable oil should comprise 10% of total calories; total unsaturated fat (fish oils, soybean, safflower nuts and nut oils) should be restricted to 20 to 22% of daily calories. Be Sure About B12 Vitamin B12 presents a particular problem for the elderly because older digestive systems often don't secrete enough stomach acid to liberate this nutrient from food. (The elderly have no problem absorbing B12 from supplements, because it's not bound to food.) Vitamins generally moderate the aging process but, ironically, that process and the diseases that frequently accompany it affect vitamin metabolism (Schweiz Rundsch Med Prax 83, 1994: 262-6). And because of those changes, we need more of certain vitamins. This is the case for vitamins D, B6, riboflavin and B12. Crucial for health, B12 is necessary to prevent anemia, and, according to recent studies, needed (along with folate and B6) to help stave off heart disease. B12, with thiamine and niacin, boosts cognition (Adv Nutr Res 7, 1985: 71-100). Screening for vitamin B12 deficiency and thyroid disease is cheap and easy and can prevent conditions such as dementia, depression or irreversible tissue damage (Lakartidningen 94, 1997: 4329-32). In the January 5-12, 1999 issue of Circulation: Journal of the American Heart Association, the AHA urged doctors to screen levels of homocysteine (the amino acid byproduct of protein digestion that damages arteries, causes heart disease and, possibly, strokes) in patients at high risk for heart disease. They also recommended all Americans to up their daily levels of vitamins B6 and B12, as well as folic acid. Since fruits, vegetables or grains lack B12, vegetarians need B12 supplements. And they're a good idea for the rest of us, too. Folic Acid Benefits Folic acid made headlines in the early 1990s when the U.S. Public Health Service declared that "to reduce the frequency of neural tube defects [spina bifida, or open spine, and anencephaly, a lethal defect of the brain and skull] and their resulting disability, all women of childbearing age in the United States who are capable of becoming pregnant should consume .4 milligrams (400 micrograms) of folic acid per day." This recommendation followed voLuminous research that showed taking folic acid was associated with a significantly reduced risk of birth defects. (The advisory is based on the fact that nearly half of all pregnancies are unplanned. If you think you are pregnant, consult your health practitioner for supplementary advice.) A Team Player Folic acid's efficacy intensifies when it works with other nutrients. Among many studies on the preventive powers of folic acid on birth defects, one published in The New England Journal of Medicine (327, Dec. 24, 1992: 1,832-1,835), disclosed an even greater decrease in neural tube defects when supplements of folic acid contained copper, manganese, zinc and vitamin C. As a warrior against homocysteine, folic acid joins the battalion of B12 and B6 in detoxifying this harmful protein. At the University of Washington's Northwest Prevention Effectiveness Center, researchers recently analyzed 38 published studies of the relationship between folic acid, homocysteine and cardiovascular disease and, according to associate professor Shirley A. Beresford, MD, folic acid and vitamin B12 and B6 deficiencies can lead to a buildup of homocysteine. Compelling Evidence Canadian researchers reported in the Journal of the American Medical Association (275, 1996: 1893-1896) that men and women with low folic acid have a 69% increase in the risk of fatal coronary heart disease. This 15-year study of more than 5,000 people stressed the need for dietary supplementation of folic acid. Folic acid also has been credited with the potential to protect against cancers of the lungs, colon and cervix. It appears to help reverse cervical dysplasia, the precursor cells to cervical cancer, especially for women taking oral contraceptives, which may cause a localized deficiency of folic acid in the cells of the cervix. According to Shari Lieberman, PhD, and Nancy Bruning, authors of The Real Vitamin & Mineral Book (Avery), folic acid derivatives work with neurotransmitters, the chemicals that permit signals to be sent from nerve fiber to nerve fiber. A lack of folic acid can cause some nervous-system disorders, such as depression, schizophrenia and dementia; it also may be related to some forms of mental retardation. Other supporting roles of folic acid, according to researchers: the formation of normal red blood cells, important for preventing the type of anemia characterized by oversized red blood cells; strengthening and improving white blood cell action against disease; limiting production of uric acid, the cause of gout. The Best Sources Many foods are rich in folic acid: beef, lamb, pork and chicken liver, spinach, kale and beet greens, asparagus, broccoli, whole wheat and brewer's yeast. But experts believe that only 25 to 50% of the folic acid in food is bioavailable. Processing also reduces an estimated 50 to 90% of its content. Folic acid supplementation overcomes these obstacles with little risk, as it has no known toxicity. Women taking folic acid who are current or former users of oral contraceptives may require additional zinc. And be sure to augment your folic acid supplement with its synergistic counterpart, vitamin B12. Focus on Fiber The American Heart Association came out squarely behind fiber in a June 16, 1997 issue of its journal Circulation: Double your daily intake to lower cholesterol and the risk of heart disease. The American diet is consistently low in fiber, notes Linda Van Horn, PhD, RD, author of the article. Twenty-five to 30 grams a day from foods (or supplements) are not only heart healthy but seem to aid weight control. Iron Problem Getting enough iron? An estimated 25% of adolescent girls in the United States are iron deficient, according to an October 12, 1996 issue of the British medical journal The Lancet, which reported that girls who took iron supplements performed significantly better on verbal tests than those who took a placebo. "Teenage girls should be regularly tested for iron deficiency because rapid growth and the onset of menstruation during puberty increase the body's need for iron," says Ann Bruner, MD, of the Johns Hopkins Children's Center and a lead author of the study.USDA data reveal that women up to age 50 also tend to get much less than recommended levels of iron, a lack of which leads to anemia, a deficiency of red blood cells, hemoglobin or volume of blood. For kids, deficiency is more common from six months to four years and during the rapid growth spurts of adolescence when the body is growing so quickly that the body's iron stores may sink to dangerous levels. Vegetarian women run the greatest risk for deficiency, as meat is iron-rich; foods like beans, grains and vegetables also contain some iron. Supplements, of course, supply easily absorbable iron. And to absorb iron from vegetarian sources, take vitamin C with your meals. That boosts the amount of this mineral you will take in. Bear in mind, however, that certain folks-older men and post-menopausal women-generally have adequate dietary supplies of iron. Of greater concern, in fact, is excessive iron, and for these folks iron-free multivitamin and mineral supplements are available. Ante Up the Antioxidants Antioxidant nutrients help protect the body from oxygen-scavenging molecules called free radicals. The products of pollution, the body's own metabolic processes and other sources, free radicals are linked to heart disease, cancer and other chronic health problems. The most important antioxidants, which include vitamin C, E, beta carotene, and selenium, are often lacking in the American diet. Plus, optimal amounts of vitamin E cannot be consumed from food. You need supplements. The bottom line: even though we live in a land of plenty, you can still miss vital nutrients. So make sure to consume these vital substances. Sprouts: Nutritional Source of Missing Nutrients In the search for the nutrients missing from America's diet, one big help is the sprout. The sprout is truly one of nature's heavyweights: fresh, tiny and moist, its power punch of vitamins, minerals, protein, chlorophyll and disease-busting phytochemicals land it in a weight class far beyond that of its full-grown competitors. Size does NOT matter to this nutritional giant. A championship belt currently wraps around the miniscule broccoli sprout, catapulted into the ring by Paul Talalay, MD, professor of pharmacology and molecular sciences at Johns Hopkins University. Dr. Talalay discovered that the seedlings contain substantially more of the cancer-fighting substance sulforaphane than mature plants (Proc. Natnl. Acad. Sci. USA, 94, 10367-10372). Sprouts, the quintessential health food of the Sixties, provide a wonderfully varied and versatile way to get your daily greens. Raw or cooked, strong or mild, vegetable and grass sprouts and their algae cousins add low-calorie texture to recipes and a rich, diverse complement of nutrients and fiber. Ancient Asia to the Modern Lab Asians stir-fried sprouts as one of the earliest fast foods as long as 5,000 years ago. The ancient Chinese relied on sprouts for year-round vegetables in colder regions of their vast country. Today, researchers studying sprouts and adult plants have identified their important chemoprotective and other health-bolstering substances. In Paul Talalay's research project at Johns Hopkins, scientists found that three-day-old broccoli sprouts contain up to 50 times more sulforaphane than mature plants, which prompts the body to produce an enzyme that prevents cancer tumors from forming. Uniform levels of the compound saturate the shoots, unlike the chemically uneven adult plants. The Brassica family of broccoli and cabbage is richly endowed with phytochemicals that also help reduce estrogen levels associated with breast cancer. Other phytochemical compounds in the Brassica family are associated with the prevention of stomach and lung cancers. Most of the initial landmark work on phytochemicals' cancer-fighting powers has taken place since 1989 under the aegis of the National Cancer Institute's "Designer Food Program," which isolated, for example, the isoflavones in beans that seem to neutralize cancer-gene enzymes. Strong Suit: Soy and Spirulina The isoflavones and phytosterols in soy produce an estrogenic effect that appears to relieve menopausal symptoms and help prevent breast cancer. Soy foods expert Mark Messina, PhD, has done extensive work on the subject, some of which has been published in the Journal of the National Cancer Institute 83, 1991: 541-6. Researchers also have synthesized a bone-strengthening form of soy isoflavones called ipriflavone, following impressive clinical trials in the treatment of osteoporosis (American Journal of Medicine, 95 [Suppl. 5A] (1993): 69S-74S). Spirulina and other micro-algae are fascinating organisms that inhabit a niche between the plant and animals kingdoms. Named for its tiny spirals, spirulina, a blue-green algae, grows in saline lakes but is cultured for maximum nutritional content. In her book Whole Foods Companion (Chelsea Green), Dianne Onstad notes that spirulina contains "the highest sources of protein, beta carotene and nucleic acids of any animal or plant food." Its nucleic acids, she says, benefit cellular regeneration; its fatty acids, especially GLA and omega-3 acids, make it one of the most complete foods. Sprouts, like any other produce, should be rinsed thoroughly before serving. People at high risk for bacterial illness-young children, the very elderly or folks with weakened immune systems-should limit their consumption of raw sprouts. But no matter how you eat them, you may find more spring in your step from these tiny, sprouting nutritional wonders.

Sugar Solution by Kristin Daniels Energy Times, January 4, 2002 Sugar Solution by Kristin Daniels Low blood sugar-a blood sugar recession-can make the good times recede. While you can't live without blood sugar, too much or too little wreaks havoc on your body and mind. And when blood sugar dips low enough to cause hypoglycemia you may feel like your emotions have been shredded. Knowing how the body regulates blood sugar allows you a measure of control in keeping blood sugar in the proper groove, and makes life a little sweeter. Hypoglycemia occurs when you feel dragged out because of low blood sugar. Ironically, this low blood sugar syndrome may be caused by an overabundance of sugar in your meals and snacks. Those who point to hypoglycemia as a widespread problem claim that up to two of three women in America suffer from hypoglycemia. That would make it an epidemic of monstrous proportions. In a survey of 1000 folks complaining of hypoglycemia, published in the Hypoglycemia Support Foundation's winter 2000 edition, researchers found that low blood sugar sufferers complained of hypoglycemic discomforts in several main categories: 94% of the people in the study reported nervousness, 89% mentioned irritability, exhaustion affected 87%, depression struck 86% and drowsiness hit 73%. Other miseries included fatigue, cold sweats, tinnitus (ringing of the ears), rapid heart rate, blurry or double vision, confusion, sudden hunger, convulsions, sweating, sleeping problems, paleness, muscle pain, memory loss, crying jags, fainting and dizziness.
