A Cell Reports study found the cholesterol metabolite 27-hydroxycholesterol promotes ER-positive breast tumor growth in mice. Patients' tumors carried higher 27-HC and less of the enzyme that clears it, and lower enzyme levels tracked with poorer survival.

Early nutrition affects leukemia risk
A Cancer Causes & Control study of 139 Greek children with leukemia found higher intake of added lipids linked to greater risk, while milk and dairy products and high protein intake were linked to lower risk. The authors suggest early-life diet may matter for prevention.

It's saturated fat from meat, not obesity that boosts breast cancer risk
In a Breast Cancer Research study, mice exposed to a carcinogen during puberty and fed a 60% fat, mostly lard diet developed mammary tumors earlier than those on a low-fat diet, and a later low-fat diet did not undo the effect. Risk did not track weight gain.

Can drinking coffee cut risk of cardiovascular disease and death?
A meta-analysis of 36 prospective cohort studies in Circulation found a non-linear link: people drinking 3.5 cups a day were 15% less likely to have cardiovascular disease than non-drinkers, with the lowest risk at 3 to 5 cups a day and no elevated risk among heavy drinkers.

What Turkey Producers Won’t Tell You
Some U.S. turkeys are fed beer to fatten them, the Associated Press reported, and Johns Hopkins and Arizona State researchers found traces of acetaminophen, diphenhydramine and fluoxetine in poultry feather meal. The arsenic drug nitarsone remains in use for the first six weeks.

Breast cancer news: Breast cancer linked to high meat and high fat diet
A Taiwanese study comparing 98 breast cancer patients with 103 age-matched controls found women eating the most of a meat-and-fat dietary pattern were nearly three times as likely to have breast cancer as those eating the least. Heavy meat eaters also used more cooking oil.

Tree nuts may help prevent pancreatic cancer
Among 75,680 women in the Nurses' Health Study, those eating a one-ounce serving of nuts twice a week or more were 35 percent less likely to be diagnosed with pancreatic cancer, independent of age, obesity, smoking and diabetes. The authors stress this is an association, not proof of cause.

Flaxseed enriched diet reduces ovarian cancer severity
Laying hens fed a diet with 10 percent flaxseed for a year had fewer late-stage ovarian tumors than hens on a standard diet, and the reduction tracked with lower ovarian PGE2 and less COX2 expression, researchers report in PLEFA.

Sesame seed paste helps type 2 diabetes mellitus patients to prevent heart disease
In a six-week trial, 41 people with type 2 diabetes who ate 28 grams of sesame seed paste daily at breakfast lowered their triglycerides and atherogenic index of plasma, with smaller drops in total and LDL cholesterol. Weight and blood pressure did not change.

Probiotic from Japanese pickle better than influenza vaccine at preventing flu?
Japanese researchers isolated a Lactobacillus brevis strain from suguki, a pickled turnip, and reported in Letters in Applied Microbiology that mice fed it were protected against influenza infection. How it works is unknown; a human trial of a drink containing the strain is under way.

Whole grains, nuts and legumes slow cognitive decline, so do DASH and Mediterranean diets
Among 3,831 Utah residents aged 65 and over followed for 11 years, those adhering most closely to DASH or Mediterranean eating scored about one point higher on a mental state exam than the least adherent. Whole grains, nuts and legumes showed a similar edge.

Fast food linked to type 2 diabetes mellitus
Among 20,835 overweight and obese Dutch participants, those eating a pattern heavy in soft drinks, fries and snacks faced a 70 percent higher risk of type 2 diabetes. A pattern built on fish, chicken, wine, raw vegetables and fruit juices showed no link after adjustment.

Soft drinks cause kidney dysfunction
Two studies presented at ASN Kidney Week 2013 link sweetened drinks to kidney trouble: drinking two or more soft drinks a day was associated with proteinuria, and moderate fructose intake in rats raised kidney salt reabsorption by increasing sensitivity to angiotensin II.

Fast food linked to type 2 diabetes mellitus, obesity
CARDIA data on 3,031 black and white adults aged 18 to 30, surveyed at enrollment and again 15 years later, showed how often people ate fast food tracked with changes in body weight and insulin resistance. Those eating it more than twice a week at both points gained about 10 extra pounds.

Pomegranate juice or supplements may fight memory dysfunction
In a pilot trial, patients taking 2 grams of pomegranate extract daily for a week before and six weeks after bypass or valve surgery kept more of their memory than placebo patients, who showed significant post-surgery deficits in memory retention.

Flaxseed intake linked to lower breast cancer risk
A Canadian case-control study of 2,999 women with breast cancer and 3,370 without linked eating flaxseed to 18% lower risk and flaxseed bread to 23% lower. None of 19 candidate factors acted as confounders, and the authors call it the first report on flaxseed alone.

Red and Processed Meat Products Linked to Mortality
A meta-analysis of nine studies in the American Journal of Epidemiology calculated a 23 percent higher mortality risk for people eating the most processed meat and a 29 percent higher risk for those eating the most total red meat, compared with those eating the least.

Coffee, chocolate may help HIV carriers with hepatitis C virus
In a French cohort of patients co-infected with HIV and hepatitis C, those drinking three cups of coffee a day were 35% less likely and daily chocolate eaters 43% less likely to show abnormal ALT. Combined intake tracked with 40% lower odds of abnormal liver enzymes.
