Among 76,661 Japanese adults followed 11 years, never-smoking men in the top quarter for isoflavone intake were 57 percent less likely to be diagnosed with lung cancer, with a similar pattern in never-smoking women. Current and former smokers showed no such link.

Could drinking beer help cut osteoporosis risk?
Testing 100 commercial beers, University of California researchers found silicon contents of 6.4 to 56.5 mg/L, with light malts richer than dark. The study measured content, not bone outcomes, though a separate Spanish study of 1,697 women found beer drinkers had greater bone density.

Can chocolate lower your risk of stroke?
A review of just three studies found mixed results on chocolate and stroke: one of 44,489 people tied a weekly serving to 22 percent lower stroke risk, a second tied 50 grams a week to 46 percent lower stroke death, and a third found no link. The author says more research is needed.

Could Eating Chocolate Prevent Heart Attack Death?
Among 1,169 Swedish patients followed eight years after a first heart attack, those eating chocolate twice or more a week had 56% lower cardiac mortality than those who never ate it. The observational design cannot show cause, and the authors want confirmation.

What You Need to Eat to Fight Heart Disease
The CDC's American Heart Month advice tells women to eat more fruit and vegetables and limit sugar, salt and fat; one observer wants specifics. A roundup of earlier studies follows, including vitamin K2 tied to 9 percent lower coronary heart disease risk per 10 micrograms a day.

Featured products: chill soda
A product write-up of Chill Beverage Company's low-glycemic organic soda, which avoids simple sugar and high fructose corn syrup, adds antioxidants and vitamins C and D, and lists 21 grams of sugars per 12 ounces. The writer notes the type of sugar used is not actually disclosed.

Why Grass Fed Dairy Products Are Better for You
Only 10 to 15 percent of US dairy farms are pasture-based, but Mercola argues grazing cuts fuel use, erosion and pollution, and that milk from pastured cows has repeatedly tested higher in vitamin E, beta-carotene, omega-3 and CLA. Pastured cows are also culled less often.

Roasting Does More than Enhance Flavor in Peanuts
USDA Agricultural Research Service scientists roasted peanuts at 362 degrees for up to 77 minutes and found darker roasts raised water- and oil-soluble antioxidant capacity in peanuts and peanut flour. Peanut skins, usually discarded as waste, scored high at every roast level.

Breastfeeding good for both the baby and the mother
A review by Stuebe in Reviews in Obstetrics and Gynecology reports infants who are not breastfed face higher risks of infection, childhood obesity, diabetes, leukemia and SIDS, while mothers who do not breastfeed face higher risks of premenopausal breast cancer, ovarian cancer and diabetes.

Blueberry Boosts Memory
Volunteers in their 70s with early memory decline who drank 2 to 2.5 cups of blueberry juice daily for two months did significantly better on learning and memory tests than a control group. The authors call the findings preliminary but encouraging.

First evidence that blueberry juice improves memory in older adults (PR)
Volunteers in their 70s with early memory decline who drank the equivalent of about 2.5 cups of blueberry juice daily for two months improved on learning and memory tests against a control group. The researchers call the findings preliminary.

Why You Don't Want to Rely on Fortified Foods
Milk and other fortified foods often carry synthetic vitamin D2, which the piece says is less potent, shorter-lived and toxic at lower levels, with studies tying it to blood vessel irritation. Boston University testing found 8 of 10 milk samples missed their labeled vitamin D by 20 percent or more.

Mango effective in preventing, stopping certain colon, breast cancer cells (PR)
Texas AgriLife Research food scientists tested the five mango varieties most common in the U.S. and found they prevented or stopped growth in certain breast and colon cancer cell lines. Dr. Susanne Talcott notes mango's antioxidant capacity is far below blueberry, acai or pomegranate.

That Morning Cup o’Joe may lower your diabetes risk
Australian researchers led by Rachel Huxley found that drinking three to four cups of coffee or tea a day was linked to 25 percent lower diabetes risk, with similar results for decaf. They suggest compounds such as magnesium, lignans and chlorogenic acids, not caffeine, may be responsible.

Hangover impairs performance
Brown University researchers report that heavy drinking of bourbon, which carries 37 times the congeners of vodka, produced a worse next-day hangover than vodka, but impairment on next-day task performance was about the same for both drinks.

Alcohol boosts risk of breast cancer and deaths
Kaiser Permanente researchers followed 1,898 early-stage breast cancer patients and found postmenopausal women drinking more than two alcoholic drinks a day faced a 39 percent higher recurrence risk than non-drinkers. Kwan suggests alcohol may raise estrogen levels that feed tumor growth.

Coffee consumption linked to lower diabetes risk
A review in Diabetology and Metabolic Syndrome found 14 of 18 cohort studies reported substantially lower type 2 diabetes risk among frequent coffee drinkers, and an Australian meta-analysis put three to four cups a day at 25 percent lower risk. The reviewers say it is too early to advise coffee.
