Pooled data from six studies covering 170,000 people found habitual coffee drinking of more than three cups a day was not associated with higher risk of hypertension compared with less than one cup. People drinking one to three cups had a slightly higher risk researchers could not explain.

What's in a name, and what's on your salad?
A Journal of Consumer Research study found dieters rated the same dish less healthy when it was called pasta rather than salad, and ate more of a confection labeled fruit chews than the identical candy chews. Non-dieters did not sort foods by name this way.

Sugars may boost risk of certain cancers
Among 435,674 adults in the NIH-AARP study, added sugars tracked with higher esophageal adenocarcinoma risk, added fructose with small intestine cancer, and every sugar studied with pleural cancer. In women, all the sugars studied were inversely linked to ovarian cancer.

Another Reason not to binge drink alcohol (PR)
A Loyola study in rodents found binge drinking changes the immune system's inflammatory response to bone injury, which researchers say complicates trauma care and can mislead doctors reading a blood test used to time surgery. Earlier work found alcohol in 41% of fracture patients.

Alcohol plus energy drink riskier than alcohol alone
In a study of 56 college students, alcohol impaired impulse control whether or not an energy drink came with it, but those drinking both felt more stimulated than those on alcohol alone. The FDA warned four makers of caffeinated alcoholic drinks, including Four Loko's, in November 2010.

Fish oil may help fight breast cancer
Rats with chemically induced mammary tumors fed fish oil with tamoxifen showed lower expression of genes that drive tumor growth and spread than rats on corn oil. Fish oil also raised some immunity genes tied to inflammation, which may work against the benefit.

Fructose Fuels Cancer More Than Other Sugars
A UCLA study found pancreatic cancer cells handled fructose and glucose differently and used fructose more readily to divide and proliferate, which the author takes as a reason for people fighting cancer to cut their fructose intake.

UNC study helps clarify link between high-fat diet and type 2 diabetes (PR)
UNC researchers report in Nature Immunology that saturated fatty acids, but not unsaturated ones, can prompt immune cells to produce the inflammatory protein interleukin-1beta, offering a possible link between a high-fat diet, inflammation and type 2 diabetes.

'Apple a day' advice rooted in science (PR)
Florida State researchers assigned 160 women aged 45 to 65 to eat 75 g of dried apples or dried prunes daily for a year. By six months the apple group's LDL cholesterol had fallen 23 percent, HDL rose about 4 percent, and lipid hydroperoxide and C-reactive protein dropped.

Blueberries fight against obesity
Texas Woman's University graduate student Shiwani Moghe reported that mice fed the most blueberry polyphenols showed a 73% drop in lipids and those on lower doses a 27% drop. She cautions the dose still needs testing in humans.

Beer drinkers with genetic variant face high stomach cancer risk
In the EPIC study of more than 521,000 adults, people drinking over 30 grams of alcohol a day were 75 percent more likely to be diagnosed with gastric cancer, and heavy beer drinkers carrying the variant rs1230025 fared worst. Wine and liquor showed no association.

Strawberries may help stop cancer
Ohio State researchers gave 36 people about two ounces of freeze-dried strawberries daily for six months; 29 showed a drop in the histological grade of precancerous esophageal lesions. Lead author Tong Chen calls the data preliminary.

When are Hotdogs Better for You than Chicken?
A study in Meat Science found pepperoni lowest in heterocyclic amines, followed by hot dogs and deli meat, while cooked bacon and rotisserie chicken held all five types tested. Mercola argues that makes processed meats lower in one carcinogen, not healthier.

The Popular Food You Should Never, Ever Feed Your Baby
A study of 20,000 women found those fed soy formula as infants were 25 percent more likely to report a uterine fibroid diagnosis, a link attributed to soy's estrogen-like isoflavones. Dr. Mercola goes further, calling soy formula the most dangerous food a parent can give a baby.

What nut is tops in antioxidants?
Joe Vinson told an American Chemical Society meeting that walnuts carry nearly twice the antioxidants of any other commonly eaten nut, at 2 to 15 times the potency of vitamin E, and that about seven a day may be enough. Roasting degrades those antioxidants.
