Eat to Live by Mary Menendez Energy Times, April 14, 2004 By now, most everyone with even a cursory interest in health knows that fruits and vegetables are more effective than foods like cheeseburgers at making your body more resistant to chronic diseases such as cancer. But beyond that generality, few people seem to know how to fine-tune their meals for the most anti-cancer bang per bite. Over the course of the lifetime of planet Earth, the plant world has devised and concocted a wealth of nutrients that can help your body fight off cancer. It's time to put them to work for you. Would you be interested in a tasty, quick way to cut your chances of certain types of cancer in half? The means to this desirable end are about as close as your refrigerator and your dining room table: All you have to do is cut open and eat a single orange every day. According to cancer research in Australia, adding that extra serving of citrus fruit to your diet every day, only once a day, boosts immunity enough to significantly lower your risk of some common cancers. " Citrus fruits [protect] the body through their antioxidant properties and strengthen the immune system, inhibiting tumor growth and normalizing tumor cells," says Katrine Baghurst, PhD, of the Commonwealth Scientific and Industrial Research Organization (CSIRO). According to Dr. Baghurst and her fellow researchers, oranges possess the most antioxidants of any fruit: more than 170 different phytochemicals. The protection you can get from oranges is due to their influence on immunity. Your immune system has the assigned task of protecting you against cells that can turn cancerous. Sixty of the chemicals in oranges are substances called flavonoids that can help the immune system fend off inflammation and tumors. Better Vegetables When Americans eat fruits and vegetables, they don't eat the ones with the most anti-cancer (or other) health benefits. Instead, we dine on the same so-so produce too frequently. If we want more health benefits from our veggies, we'd better look to expand our culinary horizons. " While people understand they should eat a variety of fruits and vegetables each day, they are not translating 'variety' in a way to capture health benefits, such as reducing their risk of developing chronic diseases," says Susie Nanney, PhD, acting director of the Obesity Prevention Center at SAINT Louis University. " People aren't eating the fruits and vegetables that contain the most nutrients," warns Dr. Nanney. "People are quite frankly confused about nutrition. I feel their pain." Unfortunately, Americans rely too often on iceberg lettuce, corn, apples, potatoes and bananas; a steady diet of that produce doesn't produce the same benefits as indulging in a wider variety of vegetarian foods. Dr. Nanney points out that the vegetables and fruits most effective at helping the body fight cancer are dark green leafy veggies, citrus (oranges, grapefruits), cruciferous vegetables (broccoli and cauliflower) and produce that has yellow or orange color. Making Dinner Plans Dr. Nanney's spectrum of desirable foods includes: Desirable Diet " When we look at how to get the most bang for your buck, the most power, it's by eating these other fruits and vegetables instead of the traditional choices," Nanney insists. Studies show that tomatoes, colored by a pigment called lycopene, may be particularly helpful in lowering men's chances of prostate cancer. For instance, research on about three dozen men with prostate cancer found that those taking supplements of lycopene and other tomato phytochemicals had smaller tumors and less spread of their cancers (Exper Bio and Med, 2002; 227: 881). The researchers conclude that "lycopene may have an antitumor effect and may be useful as an adjunct to standard treatment of prostate cancer, such as surgery, radiation therapy, hormones and chemotherapy. In addition, lycopene supplementation appears to have reduced the [spread of cancer within the prostate], suggesting that lycopene may have a role in the prevention of prostate cancer." In a study on African-American men, who suffer a higher rate of prostate cancer than other Americans, researchers also found that lycopene can limit the DNA damage that may presage cancer (Amer Chem Soc Meeting #222, 2001). " This study does not say that tomato sauce reduces cancer," cautions Phyllis E. Bowen, PhD, a nutritionist at the University of Chicago and lead investigator in the study. " It says that it reduces DNA damage that we think is associated with cancer." Tomato Consumption Other studies have confirmed the finding that men who eat tomatoes suffer less prostate cancer. And if you want the most anti-cancer benefit from tomatoes, better cook them. According to Rui Hai Liu, MD, Cornell assistant professor of food science, "[Our] research demonstrates that heat processing actually enhanced the nutritional value of tomatoes by increasing the lycopene content-[the] phytochemical that makes tomatoes red-that can be absorbed by the body, as well as the total antioxidant activity. The research dispels the popular notion that processed fruits and vegetables have lower nutritional value than fresh produce." Less Meat While you're making an effort to eat more of the colorful vegetables, you should also eat less fatty red meat and cut back on high-fat dairy foods, according to research from Harvard. In this study, which covered eight years and looked at the diets of more than 90,000 women, scientists found that those premenopausal women who ate the most fatty red meat and regular milk had the highest chance of developing invasive breast cancer. The scientists taking part in this study believe that eating more saturated fat from meat may increase hormone levels that boost the chances of breast cancer (Jrnl Natl Cancer Inst 2003;95:1079). In this research, the total amount of fat didn't affect cancer risk, but the amount of animal fat did. Women who ate the most red meat had a 54% higher chance of breast cancer. Aside from avoiding red meat, women who wish to lower their risk of breast cancer should also limit their consumption of alcoholic beverages. A study of two thousand post- menopausal women found that those who averaged about two drinks a day raised their risk of breast cancer by about 80% (Cancer Epidem, Biomarkers and Prevention, 10/03). Here, too, researchers believe that alcohol affects the level of hormones that influence cancer. The moral of the research into how food can slow cancer risk: Eat a wide variety of vegetables and fruits early and often. Limit meat and alcohol. Change the color of the fruits and vegetables on your plate for a better chance of a brighter future.

Supersized Kids by Carl Lowe Energy Times, August 1, 2003 If your kids are like most American children, they are in serious danger. Because of a lifestyle that packs in too many calories and not enough exercise, today's children are not just mildly overweight; they are fat enough at younger and younger ages to threaten their well-being. All of the extra body fat kids carry around is not just a cosmetic problem. Unless something is done quickly, this overweight generation may be doomed to a lifetime of chronic illness stemming from their excessive weight. If you have kids, they are at risk. The time to take action to save them is today. When researchers look at the weight problems of today's youth, they are shocked and dismayed. The juvenile weight problem has resulted in some kids becoming obese-grossly overweight-by their third birthdays. Scientists are also finding that, in many cases, obese 10-year-olds now have livers that are already malfunctioning because of too much body fat. At the same time, their bodies, in an effort to cope with increases in fat, are secreting high levels of insulin, making them prone to type 2 diabetes, a disease usually found in older adults. Scary Possibilities When pediatric endocrinologists at the University at Buffalo analyzed the heights and weights of young children who were referred to them, they found frightening levels of obesity (Pediatric Academic Societies meeting 5/3/00). "Childhood obesity not only affects a child's self-esteem, it also is associated with multiple medical consequences," says Teresa Quattrin, MD, professor of pediatrics and director of the study. "High insulin levels are believed to be related to type 2 diabetes, formerly known as 'adult-onset diabetes.' In fact, the incidence of type 2 diabetes in children has risen significantly in recent years, along with a high prevalence of obesity." "Children at risk of obesity must be identified very early, even at the preschool level," she adds. "Obese children often have obese parents, so an effective family-based multi-factor intervention program should begin as soon as obesity is diagnosed." Experts estimate that up to one in three US children and adolescents is already obese, and the numbers are rising. Children who are overweight are much more likely to grow up to become overweight adults and to suffer all of the health problems associated with adult obesity. Family Eating Experts believe that the best way to get children's weight under control is to get family eating under control. And the eating changes do not have to be drastic to produce effective results. "Obesity is a family illness," says Debra Haire-Joshu, PhD, director of the Obesity Prevention Center at SAINT Louis University School of Public Health. "Children...learn to become obese in an environment that encourages it. If parents are eating poorly, that's what they're providing their children." To help children eat a moderate diet, according to Dr. Haire-Joshu, parents have to eat healthier first. In her research (Preventive Medicine, 6/03), the SAINT Louis University School of Public Health joined with Parents As Teachers (PAT), a national, free educational program for parents of children from birth to age 3, to show parents simple ways to eat healthier that they could share with their children. The researchers found that when they instructed the entire family on eating fewer calories, fewer fried foods and more fruits and vegetables, everyone, including the young children, benefited. "What we showed in the study is parents who institute very simple changes can significantly impact their health. When parents have kids, they want the best for their kids. We get them at a very teachable moment," Dr. Haire-Joshu says. But society and the media produce an environment that encourages kids to eat gooey, calorie-dense food and stay glued to the television. "Our society receives consistent messages to eat more and move less. This is a way to balance some of those messages to very young families," warns Dr. Haire-Joshu. Incremental Changes Dr. Haire-Joshu says that her study shows parents are more likely to start on healthier diets when the dietary changes are relatively small. For example, instead of completely revamping meals, families that ate fried foods at five dinners during the week tried cutting back to four fried dinners. Or mothers who consistently ate at fast food restaurants were encouraged to add lettuce and tomato to a smaller burger than the supersize they usually ordered. Don't wait. Make those kinds of changes today to help your kids control their weight. Their health is at stake.
