UC San Diego researchers followed 751 men and 1,008 women, average age about 70, for 16 years and report in Public Health and Nutrition that women who often ate low-fat cheese had 132 percent higher and those drinking non-fat milk 48 percent higher rates of incident coronary heart disease.

Milk boosts prostate cancer risk and death risk from the disease
Harvard researchers tracked 21,660 physicians for 28 years and found men drinking 8 ounces of whole milk a day had 49% more fatal prostate cancer, while patients who drank whole milk faced a 117% higher risk of progressing to fatal disease.

Mice whose mothers ate a diet rich in omega-6 polyunsaturated fatty acids during pregnancy and nursing showed poorer sociability as adults, a trait seen in people with autism, along with more anxiety on the elevated plus maze.

Processed meat linked to thyroid cancer
Among 73,317 women in the Shanghai Women's Health Study followed 11 years, those with the highest dietary nitrite intake were twice as likely to develop thyroid cancer as those with the lowest. Nitrate intake showed no association; 164 cases were identified.

Drinking too much alcohol leads to visual impairment
Among current drinkers in a study of 42,713 adults aged 50 and older, more than one drink a day carried 21 percent higher risk of visual impairment and binge drinking 32 percent higher. Overall, drinking showed no link to distance or near vision impairment after adjustment.

New Study: Probiotics Help Prevent Cervical Cancer
In a 54-woman pilot study, HPV-positive women with low-grade cervical lesions who drank a probiotic were twice as likely as non-users to clear cytological abnormalities in six months, and 29 percent cleared HPV against 16 percent. The authors call the finding exploratory.

Drinking tea reduces ovarian cancer risk
Comparing 500 ovarian cancer cases with 500 controls at four Guangzhou hospitals, researchers found women who regularly drank green, black or oolong tea about 70% less likely to have the disease after adjusting for confounders.

Omega-6 PUFAs not linked to heart failure
In 788 case-control pairs from the Physicians' Health Study followed a mean 17.1 years, total plasma omega-6 PUFAs showed no significant link to heart failure. The highest levels carried about 15 percent lower risk, a difference the researchers called statistically insignificant.

Diabetes Mellitus Cure in Kitchen: Oyster Mushroom
An alcoholic extract of oyster mushroom significantly lowered serum glucose in mice made diabetic with alloxan, and cut cholesterol, triglycerides and LDL while raising HDL. The authors conclude it also improved hyperlipidaemia and impaired kidney function in these animals.

Men with prostate cancer should not drink whole milk
Among 3,918 men with localized prostate cancer followed to 2008, those in the top fifth for whole milk intake were 2.15 times as likely to see the disease progress, while the highest low-fat dairy eaters were 38 percent less likely. Total milk and dairy intake showed no link to lethal disease.

Butter, dairy fat linked to high risk of death from all causes, ischemic heart disease
Following 120,852 Dutch adults for 10 years, Bausch's team found each extra 10 grams a day of butter or dairy fat matched 4 percent higher all-cause and ischemic heart disease mortality in women, but not in men. Fermented full-fat milk ran the other way.

Soy milk, your next weapon to fight obesity?
In a trial of 24 overweight and obese women who drank 240 ml of soy or cow milk daily for four weeks each, waist circumference fell 2.78 percent during the soy milk period versus 1.78 percent with cow milk. Weight, blood pressure, liver enzymes and glycemic measures did not differ.
