The piece champions selenium, citing the journal Disease Prevention and Treatment on its action against several cancers and a 1996 University of Arizona study in which 1,300 cancer patients taking 200 mg daily for seven years were 42% less likely to have a recurrence.

Eating fish helps prevent eye disease
Two Australian studies in Archives of Ophthalmology tie diet to age-related macular degeneration. In one, following 2,454 people from 1992 to 1994, eating fish once a week was associated with 31% lower risk after adjusting for age, smoking and gender.

Diet prescribed for high blood pressure proves a powerful foe for heart failure
Among more than 36,000 Swedish women aged 48 to 86 surveyed in Emily Levitan's study, those whose diets most closely matched the DASH pattern were 37 percent less likely to suffer heart failure. DASH is high in potassium, magnesium, produce, nuts and fiber and fairly low in fat.
Vitamins
Folic acid linked to reduced risk of preemie births
A University of Texas study of 35,000 women found those taking folic acid for a full year before conception were 50 percent less likely to deliver before 37 weeks, 70 percent less likely to have a spontaneous birth at 20 to 28 weeks and 50 percent less likely at 28 to 32 weeks.

CSPI: Restaurants serve meals high in salt
CSPI told the Senate Finance Committee that 85 of 102 meals it checked at 17 chain restaurants carried more than a day's worth of salt, some nearly four days' worth. Red Lobster's Admirals Feast topped the list at 7,106 mg, against a recommended 2,300 mg daily limit.

Alcohol Responsible for 1 in Every 4 Cases of Dementia
Writing in Alcohol and Alcoholism, Jane Marshall and Irene Guerrini estimate one in four dementia cases may be attributable to alcohol abuse, with women especially at risk. Other researchers cited hold that moderate drinking is linked to lower Alzheimer's and vascular dementia risk.
Diet
Why we overeat
Former FDA commissioner David Kessler says the food industry builds foods layered with fat, sugar and salt that light up the brain's dopamine pathway and drive what he calls conditioned hyper-eating, in which people keep eating without hunger. His book is The End of Overeating.
Food
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.
Food
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.
Minerals
Selenium strikes powerful blow to skin cancer
A study of 458 Australians in Cancer Epidemiology Biomarkers and Prevention linked higher blood selenium to fewer cases of basal cell and squamous cell carcinoma, a roughly 60 percent reduction, while finding no link between vitamin E levels and reduced carcinoma risk.
Vitamins
B6 cuts colorectal risk
A Harvard study links adequate vitamin B6 to as much as a 60% lower colorectal cancer risk, above the 20% reduction earlier Scottish trials estimated. Patients with colorectal cancer showed high homocysteine, which tracks with low B6 and B12.
Food
Omega-6s found to be essential to heart health
William Harris of Sanford Research/USD reviewed about two dozen studies and found people eating the most omega-6 fats had lower rates of heart disease. He suggests replacing calories from saturated fat and carbohydrates with omega-6s, a position the American Heart Association shares.
Minerals
Prenatal iron deficiency may delay brain maturation in preemies
In a study of 80 infants followed past 18 months, University of Rochester researchers found premature babies with low cord blood iron had abnormal maturation of the auditory nervous system. Dr. Sanjiv Amin says the delay may have implications for later language development.
Supplements
Omega-3s strike blow to heart failure
Researchers followed about 40,000 Swedish men aged 45 to 79 between 1998 and 2004 and found those eating the most omega-3s were up to 33 percent less likely to develop heart failure; one serving of fatty fish a week was linked to a 12 percent lower likelihood.
Food
The case against wine uncorked
A Dutch study following nearly 1,400 men over 40 years found wine drinkers lived about four and a half years longer than abstainers. The American Cancer Society counters with the Million Women Study, where low to moderate drinking raised risk of several cancers, including breast.
Food
High-fat foods boost memory
UC Irvine researchers report that rats given the fat-derived compound OEA remembered water-maze tasks and unpleasant experiences better, apparently because OEA activates memory signals in the amygdala. Piomelli warns it may also drive long-term cravings for fatty food.
Vitamins
Nutrient protection against arsenic toxicity
Researchers measuring urinary arsenic metabolites and blood micronutrients in 165 six-year-olds in Bangladesh report that low folate and cysteine may hamper arsenic methylation, and that children appear to metabolize and excrete arsenic more efficiently than adults.
Supplements
Caffeine-containing botanicals in dietary supplements
USDA's Nutrient Data Laboratory analyzed caffeine levels in sports-nutrition, weight-loss, vitamin and mineral supplements bought the same way consumers buy them. U.S. labels need not state caffeine amounts, and botanicals such as guarana, yerba mate, kola nut and green tea extract supply it.
