Polyphenols: The Powerful, Health-Boosting Nutrients in Rainbow-Colored Foods
April 25, 2022 11:54 AM
Polyphenols are a type of nutrient found in a variety of Rainbow-colored foods. These nutrients offer a range of health benefits, from boosting your immune system to protecting your heart. Polyphenols are especially beneficial for promoting good health and preventing disease. In this blog post, we'll discuss what polyphenols are, where you can find them, and some of the health benefits they offer.
What are polyphenols and what do they do for the body?
Polyphenols are a type of micronutrient that are found in plant foods. They're known for their antioxidant properties, meaning they help to protect cells from damage. Polyphenols can also help to reduce inflammation and promote heart health by reducing cholesterol levels and blood pressure. Some research has also shown that polyphenols may help to prevent certain types of cancer. The body needs polyphenols for several different functions, making them an important part of a healthy diet. Most people consume adequate amounts of polyphenols through their diet, but those who don't eat many plant foods may want to consider taking a supplement.
Polyphenols and cancer prevention
Research has shown that polyphenols may play a role in cancer prevention. One mechanism by which polyphenols may protect against cancer is by inhibiting the growth of cancer cells. Polyphenols may also help to protect DNA from damage, which can lead to the development of cancer. Additionally, polyphenols can induce apoptosis, or cell death, in cancer cells. Some studies have also suggested that polyphenols may help to reduce inflammation, which has been linked to the development of cancer. While further research is needed to better understand the role of polyphenols in cancer prevention, the existing evidence suggests that consuming polyphenol-rich foods may help to reduce the risk of developing cancer.
Polyphenols and heart health
Polyphenols are known for their antioxidant properties and have been linked to a number of health benefits, including heart health. Some studies have shown that polyphenols may help to reduce the risk of cardiovascular disease by reducing inflammation and improving blood vessel function. Polyphenols may also help to lower blood pressure and cholesterol levels, two key risk factors for heart disease. While more research is needed to confirm these benefits, consuming foods rich in polyphenols is a simple way to support heart health. Good sources of polyphenols include fruits, vegetables, nuts, seeds, and vitamin supplements. Including these foods as part of a healthy diet is a good way to ensure that you're getting adequate levels of this important micronutrient.
Polyphenols and brain health
While they are sometimes necessary in small quantities for human health, recent research has suggested that they may also have beneficial effects on brain health. One study found that polyphenols may help to improve cognitive function in older adults, while another found that they may help to reduce the risk of dementia. Additionally, polyphenols have also been shown to protect neuronal cells from damage and death. As a result, consuming foods rich in polyphenols may help to protect the brain from age-related decline.
The benefits of polyphenols for overall good health
Polyphenols can also help to improve gut health by promoting the growth of healthy bacteria and reducing inflammation. In addition, polyphenols have been shown to boost the immune system and reduce the risk of chronic diseases such as diabetes. Given their wide range of health benefits, it is no surprise that polyphenols are sometimes referred to as the "supernutrient." However, more research is needed to determine the optimal intake of polyphenols for human health.
How to get more polyphenols in your diet
Polyphenols are a type of micronutrient that has been shown to offer a variety of health benefits. They are found naturally in bright colored fruits and vegetables, but the best way to get a high concentration of polyphenols is through a supplement. If you want to spare your self the calories of consuming large amounts of fruits and vegetables, one can take a supplement like Source of Life Red Lightning, which contains 30 whole foods and super fruits, its packed with antioxidants and polyphenols.
Polyphenols have been shown to improve heart health, reduce inflammation, and boost cognitive function. In addition, they are believed to play a role in cancer prevention. While more research is needed to confirm these health benefits, there is no doubt that polyphenols can have a positive impact on overall health. If you are looking for a way to improve your health, consider adding a polyphenol supplement to your diet.
Eat fruits and vegetables of many colors for optimum health

There is a saying that you should eat the rainbow. This saying does not refer to a Skittles campaign but the USDA campaign about eating more colors of vegetables. The modern diet is fairly gray and brown and this introduces these vegetables to your diet. These vegetables contain many of your required minerals like calcium in broccoli, or potassium in cabbage. These all contain phytonutrients which have been shown to lower cholesterol as well as inflammation.
"When it comes to improving your health and the health of your family, fruits and vegetables are pure superstars!"

8 foods ALL men should be eating and even steak's on the menu
February 15, 2017 02:59 PM
Men should eat more oily fish like fresh salmon, tuna and trout, which are rich in omega-3 fatty acids. These fats cut the risk of heart disease. Red peppers are a great source of vitamin C, which men need if they are trying to have a baby. Red kidney beans, a rich source of fiber, should be on the diet, too. Fiber helps in digestion and cuts the risk of heart disease, diabetes and high cholesterol
"Try eating one or two servings of oily fish each week either as grilled fillets or even dips such as smoked mackerel pate."
Want to Eat Better? Just Eat More Color
January 21, 2017 12:59 PM
I've heard of eating the Rainbow. This talks more about that. Eating a wide variety of color when it comes to fruits and veggies helps you get the proper balance of nutrients. The different colors mean different vitamins and minerals are present in the food. A varied diet is both healthful and more interesting so no one gets tired of the same thing.
"Produce companies rarely include information on which phytochemicals are in their foods, making it even more important you know nature's color coding system."
What Are The Benefits Of Vitamin E?
April 17, 2014 05:01 AM
Vitamin E is composed of eight fat soluble vitamins and it’s available in four different forms. The fat soluble antioxidant can only be obtained in food as a supplement. They help in prevention of oxidative stress in the body and other vitamins.
There are different varieties of foods rich in vitamin E in terms of nutrients density with examples such as:
1. Tofu light, silken with a 25% daily value in every 5.3 mg.
Health benefits of vitamin E.
The health benefits come from the vitamins antioxidant property which remove free radicals that damage the cell structure due to its unstable compounds. It improves immunity and reduces cholesterol thereby reducing the risk associated with developing cancer.
Vitamin E prevents the blood platelets from clumping. Heart diseases, sunstroke and coronary artery disorders are prevented through consumption of high levels of vitamin E.
Vitamin E owing to its properties of antioxidant, promotes blood circulation to the scalp which help in reducing fatigue and make capillary walls more stronger for nourished cells.
Vitamin E oil facilitates the healing process and since it’s extremely versatile, the vitamin E absorbed in the epidermis layer is used in treating and preventing sunburns.
Since vitamin E speeds up cell generation, it’s used to treat acne, scars, and wrinkles which makes the skin to appear more younger due to its anti-aging effect.
Vitamin E helps the skin to maintain its natural moist and appear to be more fresh. It’s also used to treat nails and cuticles by applying a few drops of vitamin E on them.
Vitamin E is believed to promote eye health and reduces the risk of eye damage associated with old age by 20%. i.e macular degeneration.

Enjoy the Rainbow – the Color Wheel of Fruits and Vegetables
We’ve all heard the statistics, and have probably seen the signs in the produce section of our favorite grocery store: eating 5 servings of fruits and veggies a day is important,
Chances are also pretty good that we’ve also seen the newest food pyramid, encouraging Americans to “eat a Rainbow of frits and vegetables.” That is, choose from the rich variety of colors for the best all-around health benefits.
In this Ask the Doctor, we’re going to look at the unique health components of different colored fruits and vegetables, and why they’re so important. Plus, we’ll learn about supplemental options, like fruit and vegetable drink mixes, for those days when our diets just aren’t that great.
Q. What’s the big deal about fruits and vegetables?
A. Well, for the main reason that they are whole foods – created by nature (or at least generations of farming) and are rich in a variety of nutrients. Processed foods can’t match the health benefits of strawberries or broccoli – items that have fiber, vitamins, and enzymes built right in.
Q. What does “eating a Rainbow” of fruits and vegetables really mean?
A. This is simply an easy way of remembering to get as much color variety in your diet as possible to maximize your intake of a broad range of nutrients. The colors of fruits and vegetables are often a tangible clue to the unique vitamins and other healthy substances they contain. Getting a variety of colors, therefore, means getting a variety of the essential nutrients your body needs to stay healthy and strong.
Enjoying the Rainbow: Fruit and Vegetable Benefits:
Q. Can you tell me a little more about the healthy components of fruits and vegetables?
Let’s take a look at some of the most well-studied and important nutrients:
Quercetin is found in apples, onions and citrus fruits (also is hawthorn and other berries and apple-related fruits usually used in traditional herbal remedies and modern supplements). It prevents LSL cholesterol oxidation and helps the body cope with allergens and other lung and breathing problems.
Clinical studies show that quercetin’s main points of absorption in the body appear to be in the small intestine – about 50%. The rest – at least 47% is metabolized by the colonic micro flora – the beneficial bacteria such as Lactobacillus acidophilus and Bifidobacterium longum. You may consider adding these beneficial bacteria (found in yogurt) either through the diet or a supplemental form.
Ellagic Acid is a component of ellagitannins – dietary polyphenols with antioxidant (and possibly anticancer) properties. Polyphenols are the basic building blocks of many plant-based antioxidants. More complex phenolic compounds, such as flavonoids are created from these molecules.
Ellagic acid is found in many fruits and foods, namely raspberries, strawberries, pomegranates, and walnuts. Clinical studies suggest that ellagitannins and ellagic acid act as antioxidants and anticarcinogens in the gastrointestinal tract.
Ellagitannins are durable antioxidants, and happily, they do not appear to be diminished by processing, like freezing. This means the benefits are still strong, even in frozen packs of raspberries or strawberries, or some of the better multi-ingredient supplement drink mixes.
In scientific studies, ellagic acid also showed an anti-proliferative effect on cancer cells, decreasing their ATP (adenosine triphosphate) production. ATP is the molecule that provides the primary energy source for the cells in our bodies. In a sense, ellagic acid seems to deprive cancer cells of their fuel.
Beta-Carotene: Probably the best-known of the carotenoids, beta-carotene is converted by the body into vitamin A. Many vegetables, especially orange and yellow varieties, are rich in this nutrient. Think summer squash, yams and of course, carrots.
Beta-carotene has long been associated with better eyesight, but it has other benefits, too. In a scientific study, beta-carotene decreased cholesterol levels in the liver by 44% and reduces liver triglycerides by 40%.
Lycopene is a carotenoid mostly found in tomatoes, but also in smaller amounts in watermelon and other fruits. Clinical studies have shown that lycopene consumption may decrease the risk of prostate cancer. In fact, high intakes of lycopene are associated with a 30% to 40% reduced risk. And, as good as beta-carotene is, its cousin, lycopene, seems to be an even stronger nutrient, protecting not just against prostate cancer, but heart disease as well.
Lutein is found in many fruits and vegetables, including blueberries and members of the squash family. Lutein is important for healthy eyes, and in fact it is found in high concentrations naturally in the macular region of the retina – where we see fine detail. It is one of the only carotenoids, along with its close sibling zeaxanthin, that is found in the macula and lens of the eye.
Lutein also supports your heart, too. In a scientific study, lutein reduced atherosclerotic lesion size by 43%. In other words, high intakes of lutein may actually help prevent coronary artery disease!
Interestingly, as is the case with lycopene, cooking or processing foods with lutein may actually make it more easily absorbed.
In clinical studies, men with high intakes of lutein (and its close cousin, zeaxanthin, found in broccoli and spinach) had a 19% lower risk of cataract, and women had a 22% decreased risk, compared to those whose lutein intakes were much lower.
Vitamin C: One of the best-known nutrients out there, vitamin C keeps our immune system strong; speeds wound healing, and promote strong muscles and joints. A free-radical fighter, vitamin C prevents oxidative damage to tissues, builds strength in collagen and connective tissue, and even reduces joint pain.
Sources of vitamin C are scattered throughout the spectrum of fruits and vegetables.
Potassium: Most Americans are deficient in potassium. For the most part, it’s hard to get too much of this valuable mineral. Potassium does great things for our hearts. Higher intakes of dietary potassium from fruits and vegetables have been found in clinical research to lower blood pressure in only 4 weeks.
Many researchers believe that the typical American diet has led to a state of chronic, low-grade acidosis – too much acid in the body. Potassium helps change pH balance to a more alkaline environment in the body and increases bone density.
This was proven in the long-running Framingham Heart Study which showed that dietary potassium, (along with magnesium and fruit and vegetable intake) provided greater bone density in older individuals.
Fiber is another food component many just don’t get enough of – especially if they’re eating a “typical American diet.” Fruits, vegetables and whole grains are excellent sources of fiber. However, fiber from a good fruits and vegetable drink mix should be derived from inulin and chicory root. This soluble fiber source not only adds to the overall amount of fiber you need (25 to 38 grams a day), but also provides a nice “nesting ground” for the beneficial bacteria that populate the intestines. And, even though some fiber has a bad rap for inhibiting mineral absorption, inulin and chicory root are “bone building” fibers – they actually help the body absorb calcium.
Flavonoids are an overarching term that encompasses flavonols, anthocyanidins, and flavones, isoflavones, proanthocyanidins, Quercetin and more. They are almost everywhere: in fruits, vegetables, grains, herbs, nuts and seeds – even in the coffee, wine and tea we drink. Flavonoids are responsible for the colors in the skins of fruits and the leaves of trees and other plants.
Flavonoids have many health benefits. They can help stop the growth of tumor cells and are potent antioxidants. Additionally, flavonoids have also been studied for their ability to reduce inflammation.
Anthocyanins: High on the list of important “visible” nutrients are anthocyanins. They color fruits and vegetables blue and red.
Anthocyanins are members of this extended family of nutmeats, the flavonoids. Typically found in high amounts in berries, anthocyanins are readily absorbed in the stomach and small intestine.
As antioxidants, anthocyanins dive deep into cell membranes, protecting them from damage. IT may be one reason why the anthocyanins from blueberries are considered such an important component in battling neuronal decline, like Alzheimer’s. Blackberries, raspberries, and strawberries are also excellent sources of this flavonoids group.
SDG lignans, (short for secoisolariciresinol diglucoside) are polyphenolic components of flaxseed, pumpkin and other herbal sources. Much of the recent research surrounding lignans has focused on flaxseed. In scientific and clinical studies, lignans from flaxseed support hormonal balance and may have cancer-preventing abilities. In fact, in one study, flaxseed lignans reduced metastatic lung tumor by 82% compared to controls.
The lignans in pumpkin seed, also considered a major source, target 5-alpha reductase activity.
This enzyme catalyzes the conversion of testosterone into the more potent dihydrotestosterone (DHT). DHT, like testosterone, is a steroid hormone or androgen. Androgens are responsible for the development and maintenance of masculine sex characteristics in both men and women. Excess levels of DHT can cause serious problems with prostate or bladder health. That’s why modulation of the 5-alpha reductase enzyme is so important – it helps maintain healthy testosterone and DHT levels. By balancing the levels of these key hormones, pumpkin seed lignans provide protection for prostate and bladder cells.
In addition, pumpkin seed has been shown to modulate the enzyme aromatase. Aromatase is present in the estrogen-producing cells of the adrenal glands, ovaries, testicles, adipose tissue, and brain. Aromatase converts testosterone, an androgen, into estradiol, and estrogen.
Inhibition of the aromatase conversion can help maintain a balance of healthy testosterone levels in women, which has been shown to strengthen pelvic muscles and reduce incidence of incontinence.
In fact, a clinical study, involving a pumpkin extract in conjunction with soy, resulted in significant support for bladder health. After two weeks of supplementation, 23 of the 39 postmenopausal women enrolled in the study showed great improvement in urinary frequency and sleep. By the end of the six week study, 74.4 percent of participants found pumpkin extract safely and significantly improved “nocturnia,” that is, the need to urinate frequently at night. For individuals with 2 to 4 episodes of nocturnia prior to the stud, and 81.8% improvement was seen – also showing great improvement in sleep quality. After all, if you don’t have to wake up every couple of hours to go to the bathroom you’re bound to get better sleep.
Beta glucan: Mushrooms are intense immune-boosting powerhouses due to their beta-glucan content. Three well-studied power-house mushrooms that contribute beta glucan to the diet include maitake, reishi and shiitake.
The most significant constituents of mushrooms are long chain polysaccharides (molecules formed from many sugar units) known as beta-glucan. These huge molecules act as immunoregualtors in the human body, helping to stabilize and balance the immune system.
This includes specific support of white blood cells, or lymphocytes, the primary cells of the immune system. Lymphocytes fall broadly into three categories: T cells, B cells, and natural killer (NK) cells.
In one clinical study, 165 patients with various types of advanced cancer were given maitake mushroom compounds alone or with chemotherapy. Cancer regression or significant symptom improvement was observed in 58% of liver cancer patients, and 62% of lung cancer patients. Plus, when maitake was taken in addition to chemotherapy, the immune cell activities were enhanced 1.2 to 1.4 times, compared with chemotherapy alone.
In another clinical study, researchers determined that Reishi increased the number of cancer killing white blood cells and made them more deadly to cancer cells.
And, in a scientific study of human breast cancer and myeloma cancer and myeloma cancer cell lines, shiitake compounds provided a 51% antiproliferative effect on the cells – inducing “apoptosis’ – the programmed cell death that should occur naturally.
While beta-glucan are distributed throughout the mushroom body, the beta-glucan concentrations are significantly higher in the mycelium – the interwoven fibers or filaments that make up the “feeding structure” of the mushroom.
Bioflavonoids are commonly found in bright yellow citrus fruits, including lemons, limes and oranges. They are responsible for the bright pigment found in the skin of the fruit, and are considered a “companion” to vitamin C, seeming to extend the value of the nutrient within the body.
Hesperidin is just one of the valuable bioflavonoids found in citrus. Hesperidin appears to lower cholesterol levels, as well as support joint collagen in examples of rheumatoid arthritis.
Epigallocatechin gallate (EGCG):
Polyphenols, most notably EGCG, or epigallocatechin gallate, are well-studied and powerful components of tea. EGCG has been shown to reduce colon and breast cancer risk. Green tea also boosts the immune system and encourages T-cell formation – part of the front-line defense of our bodies against sickness and disease.
Q. I’ve been seeing articles about fruits, vegetables and supplements touting “high ORAC value.” What does this mean?
ORAC is an acronym for Oxygen Radical Absorption Capacity, and is simply a measurement of antioxidant activity of nutrients. Oxygen radicals, or free radicals, are unstable molecules. They grab electrons from other cells to use for themselves, and in the process can damage them. It is believed that free radical activity plays a role in the development of many diseases such as heart disease and cancer, and also plays a role in aging.
Antioxidants help prevent this damage by “loaning out” extra electrons to stabilize free radicals/ Consider any fruit or vegetable with a high ORAC rating as having a lot of “antioxidant power.”
I know I should eat more fruits and vegetables, but it just seems so hard to get five servings a day.
The number one excuse I hear for not buying frits and veggies is that “fruits and vegetables are too expensive.” But are they really? Certainly, fresh foods that aren’t in season and have to be shipped a distance can be a bit pricey. If anyone added up how much spend on fast food, or prepackaged or processed snacks, it would probably be shocking.
Luckily, there are many ways to get your “Daily 5”. For instance, frozen fruits and veggies retain much of their nutrient profile. They can be an excellent alternative when certain foods are out of season. So too, are fruit and vegetable drink mixes – excellent supplemental sources of some of the nutrients our bodies need most.
More recently, the American
Of course, for people not accustomed to the fiber in fruits and veggies, there is some reason to think it’ll increase gas. When cell walls break down, and fiber passes through the system, it can create flatulence. Folks who eat fruits and vegetables every day generally don’t have this problem. Their systems are already accustomed to it.
For those just starting out on a better diet, however, start slowly – it helps your body adapt. Cooking vegetables can help, too, because it begins breaking down the cell walls early on.
One thing is certain, however. The “Typical American Diet” and good health are mutually exclusive. The increase in type 2 diabetes, heart disease, high cholesterol, and hypertension all point to the abuse our bodies suffer by eating diets high in fatty meats, processed sugars, and refined grains.
Q. Can I just drink fruit and vegetables drinks in place of 5 servings of fruits and vegetables?
Green drinks and fruit and vegetable drink mixes aren’t meant to replace whole foods, but they can be an excellent substitute when you’re rushed or traveling or just trying to fill everyday nutritional gaps. Their whole food ingredients absorb very easily and gently in the gut, and many of these drink mixes contain healthy doses of fiber, too.
Green drink mixes and food-based drink mixes combine many colorful fruits and vegetables and sometimes grasses in a healthy, mixable supplement assortment. While there have been many advancements in the field of green drinks, there are only a few that take the primary reason we eat into consideration: taste!
Happily, there are some companies out there with great-tasting drink mixes that also formulate based on the color concept, ensuring you get the broadest assortment of nutrients from a full range of fruit and vegetable colors to promote optimal health.
High-quality fruit and vegetable drink mixes offer the best from nature’s color wheel in a convenient and great-tasting supplement. So, the next tie you feel like taking a coffee break – try a fruit and veggie break instead. Your body and spirit will thank you.
