Can drinking alcohol prevent dementia?
Adults aged 75 and older who drank eight to 14 drinks a week were 37 percent less likely to develop dementia over six years, a Wake Forest study of 3,069 people found. Those who already had cognitive impairment declined faster at any intake, and heavy drinkers nearly doubled their risk.

Eating fruit, vegetables reduces risk of upper respiratory tract infection
Among more than 1,000 pregnant women, those eating the most fruit and vegetables were 26 percent less likely to have an upper respiratory tract infection than those eating the least. Fruit or vegetables alone showed no link; the benefit appeared near 6.7 servings a day.

That Morning Cup of Ambition May Reverse Symptoms of Alzheimer’s
Fifty-five mice bred with Alzheimer's traits were split in two; after two months, those given caffeine in their water did better on thinking and memory tests than the water-only group. The University of South Florida researcher says it is the first work to suggest caffeine can undo damage.

Of mice and memory
University of South Florida researchers report in the Journal of Alzheimer's Disease that caffeine equal to five cups of coffee a day reversed memory impairment in aged mice bred for Alzheimer's symptoms, and cut the disease's hallmark protein in their brains and blood.

Drinking alcohol raises pancreatic cancer risk
Among 470,681 U.S. adults aged 50 to 71 followed through 2003, heavy drinkers were 45 percent more likely to develop pancreatic cancer and heavy liquor drinkers 62 percent more likely than light drinkers. The authors cannot rule out confounding by smoking.

Green tea may prevent prostate cancer
In 26 prostate cancer patients who took four green tea extract capsules daily for a month before surgery, hepatocyte growth factor fell 18.9 percent, VEGF 9.9 percent and PSA 10.4 percent, an LSU-led study in Cancer Prevention Research found. The dose matched the EGCG in about 12 cups of tea.

Curry may help fight dementia
Duke's Murali Doraiswamy reported that diets high in curcumin dissolved amyloid plaques in mice over 12 months and prevented plaques forming in young mice. He cautioned that curry cannot offset the dementia risk of an unhealthy diet. A UCLA human trial is under way.

Three cups of tea can cut heart attack risk
Dr. Carrie Ruxton of the Tea Advisory Council told Mail Online that three cups of tea a day can ward off heart attacks. She credits tea's flavonoids, whose anti-inflammatory action may aid blood vessel function and lower thrombosis risk, rather than its polyphenols.

Study proves benefit of green tea for leukemia sufferers
A Mayo Clinic study in the Journal of Clinical Oncology found high doses of the green tea compound EGCG were tolerated by chronic lymphocytic leukemia patients, stabilized early-stage disease and were accompanied by a 50 percent reduction in lymph node size.

Astaxanthin: Algae’s Little Miracle Nutrient
Naturalnews.com compiled studies crediting astaxanthin, a carotenoid from microalgae, with fighting wrinkles, easing inflammation and absorbing free radicals that damage mitochondria. It also crosses the blood-brain barrier, protecting neurons in Japanese experiments.

Gluten-free not great for gut health
A British Journal of Nutrition study from the Spanish National Research Council put ten healthy adults on a gluten-free diet for a month and found E. coli rose, beneficial bacteria such as Bifidobacterium fell, and markers of immune function dropped.

Excessive cola intake leads to muscle problems
A review in the International Journal of Clinical Practice links drinking 2 to 9 litres of cola a day to hypokalemia, with symptoms from mild muscle weakness to profound paralysis. Patients recovered once they stopped the cola and took potassium; caffeine looks like the main driver.

Turmeric extract may fight obesity
Tufts researchers fed mice a high-fat diet for 12 weeks with or without curcumin, and the curcumin group gained less weight and carried less fat tissue, which the team attributes to suppressed blood vessel growth in fat. Senior author Mohsen Meydani notes no human studies have been done.

Eating fish helps prevent eye disease

Soy: A common food with unclear benefits
Soy's standing as a superfood is under question. Its phytoestrogens can ease menopausal symptoms in women low in estrogen, one researcher says, while others suggest heavy consumption by a pregnant mother may affect male fetal development. The studies conflict.

Dried plums may cut appetite cravings
In a San Diego State trial, women who ate a 238-calorie serving of dried plums reported greater satiety before their next meal than women given low-fat cookies. A companion trial linked the plums to healthier lipid levels and bowel habits.
