The Healthy Eating–Cancer Protection Link Gets Stronger
Colorectal cancer is a leading cause of cancer-related deaths in both men and women in the United States. Smoking, having a sedentary lifestyle, and being overweight all add to colon cancer risk, but eating lots of fruits and vegetables, getting plenty of fiber, and eating less red meat can reduce the risk.
A study recently published in the Journal of Nutrition, looked at the influence of three different diets on colorectal adenoma, a benign tumor that can lead to colorectal cancer:
• The US Department of Agriculture Food Guide recommendations (previously known as the US Food Guide Pyramid) are intended to prevent chronic diseases such as heart disease, diabetes, and cancer. This plan emphasizes fruits, vegetables, and whole grains while restricting saturated fat and sugar. It also specifies the number of daily servings from specific food groups.
• Another set of USDA dietary recommendations—the Dietary Approaches to Stop Hypertension (DASH) diet—has been found to lower blood pressure and reduce cardiac risk. This plan also emphasizes fruits, vegetables, and whole grains; restricts saturated fat and sugar; and specifies the number of daily servings from specific food groups.
• Many nutritionists recommend a Mediterranean diet because it has been linked to good health and heart disease prevention in numerous studies. The Mediterranean diet does not dictate specific amounts of foods, but it emphasizes fruits, vegetables, legumes, whole grains, and foods high in monounsaturated fatty acids such as olives, olive oil, avocado, and nuts and seeds.
The people in the new study—3,592 with precancerous colorectal polyps and 33,971 without evidence of polyps or cancer—answered food questionnaires, which were analyzed and scored for how well they matched the USDA Food Guide, the DASH diet, and the Mediterranean diet.
Men whose diets compared most closely with the USDA Food Guide had a 26% lower risk of colorectal adenoma than men whose diets were least comparable. Close adherence to the DASH diet resulted in 25% risk reduction, and adherence to the Mediterranean diet reduced risk by 21% in men. In women, only the USDA Food Guide eating pattern was associated with protection from colorectal adenoma, in those who smoked or were not overweight.
“Consuming a variety of foods from different food groups at the minimum daily amounts recommended by the US Food Guide Pyramid while maintaining saturated fat, added sugar, and alcohol intakes below the recommended daily intake limits was associated with significant reduction in risk of colorectal adenoma in men and women,” the researchers concluded. “Findings from our study suggest that following current US dietary recommendations or a Mediterranean dietary pattern could improve colorectal cancer prevention and control, especially in men.”

Herbal Help for a Common STD
Healthnotes Newswire (November 21, 2007)—A study finds that green tea extract may be an effective treatment for genital warts—one of the fastest growing sexually transmitted diseases, according to the study’s authors.
Typical treatments for this condition include freezing (cryotherapy), laser treatment, and podofilox topical gel, which may be painful and expensive and often fail to prevent recurrence. The new study examined the role of catechins—a component of green tea leaves—which have anti-inflammatory, immunomodulatory, and antitumor properties—as a treatment for genital warts caused by human papillomaviruses (HPV).
The study looked at the effect of polyphenon E, an extract of green tea leaves from the Camellia sinensis species, on 242 people with genital warts. They were randomly assigned to receive polyphenon E 15% ointment, polyphenon E 10% cream, or placebo and instructed to topically apply their assigned treatment three times a day for 12 weeks.
The 15% ointment was the most effective treatment for clearing genital warts; no differences in recurrence rates were noted among the treatment groups. About 8% of the people experienced local skin reactions and other side effects. However, most were mild and subsided over the course of the study.
Studies in China have also shown that green tea extract can be a effective genital wart treatment, and there is some possibility that oral administration of polyphenon E might also be effective. The authors conclude, “Polyphenon E is a favorable new self-applicable treatment for external genital warts with properties that differ from other treatments.”

Tea Time: The World’s Favorite Beverage Helps Build Strong Bones
Parents: Eating Omega-3s May Prevent Type 1 Diabetes - - By Jane Hart, MD
Healthnotes Newswire (November 15, 2007)—A new study published in the Journal of the American Medical Association found that among children at risk for developing type 1 diabetes, those whose diets contained more omega-3 fatty acids—found in fatty fish such as salmon, mackerel, and albacore tuna—were less likely to develop a precursor to type 1 diabetes.
Islet autoimmunity is an immune process where antibodies attack the insulin-secreting (islet) cells in the pancreas. The destruction of these cells leads to type 1 diabetes. Children are considered at risk for islet autoimmunity if they have a parent or sibling with type 1 diabetes or if a blood test shows they have a specific gene associated with the disease.
The study, called the Diabetes Autoimmunity Study in the Young (DAISY) trial, examined the dietary habits of 1,770 children at increased risk for type 1 diabetes. Researchers then assessed the amount of polyunsaturated fatty acids in their diets (through use of a parent-reported food frequency questionnaire) and the subsequent development of islet autoimmunity. More omega-3 fatty acids in the diet was associated with a decreased risk of islet autoimmunity and type 1 diabetes. Dietary intake of omega-6 fatty acids was not associated with islet autoimmunity risk.
Omega-3 fatty acids are known to have anti-inflammatory properties and to reduce oxidative stress. These mechanisms may help protect against islet autoimmunity but the exact way in which omega-3 fatty acids may protect against type 1 diabetes is not known.
“Our study suggests that in the future, after more research has been done, we may be able to develop nutritional-based interventions to prevent type 1 diabetes,” said Jill Norris, MPH, PhD, lead author of the study and professor of Preventive Medicine and Biometrics at the University of Colorado at Denver and Health Sciences Center. “However, it is important to note that because our study is the first study to find this, our findings are preliminary, and should be interpreted with caution until additional research is done.”

Bone Strength Take Care
Bone Strength Take Care |
Whole-Food Cal/Mag Vitamin D3 and K2 Complex
Available in 30, 60, and 120 tablet sizes
- Bone-strengthening calcium your body recognizes as food
- With AlgaeCal®, a proprietary plant source of calcium
Evidence suggests that calcium from whole food sources may produce more favorable effects in bone health than isolated calcium supplements.* Similar to most nutrients, the body can utilize calcium much more effectively when it is paired with its natural co-factors such as magnesium and other trace minerals.
New Chapter® is proud to deliver a calcium complex derived from whole food that delivers these key essential nutrients in their safest, most active form within the infinite complexity of whole food.
The most common form of calcium supplement today is derived from limestone. You don’t eat rocks as part of your balanced diet, why would you choose to supplement your bone health nutritional needs with limestone?
Our bodies understand and seek whole food sources of nutrition, not rocks, which is why New Chapter formulated this product with a whole food plant source of this important nutrient complex. As whole food, it’s easy on the digestive system.
The calcium complex in Bone Strength Take Care™ is derived from a special form of plant called Algas Calcareas (AlgaeCal®) that is harvested from the pristine shores of a protected national reserve park in South America. Much like the vegetables from an organic garden, the algae is harvested live and then cold processed to retain its nutritional value.
Calcium must be completely dissolved in order to be absorbed. The plant-based calcium found in Bone Strength Take Care is porous, which dramatically increases the calcium’s surface area. Stomach acid can then come into greater contact with the calcium, making it easy to dissolve.
In addition to the whole-food source of calcium and magnesium, we have also added other bone-nourishing nutrients to complete the food complex.
Vitamin K is an essential co-factor in calcium absorption and retention. Human cell proteins that don’t get enough Vitamin K can’t hold onto calcium, causing this critical nutrient to drift away from the bone. Vitamin K2 (MK-7), sourced from fermented whole food, gently redirects “lost” calcium back into the bone bank.
Vitamin D3 completes the complex. Numerous studies have found that Vitamin D aids bone support and function.*
