Salk Institute researchers fed mice a high-fat, high-calorie diet, giving one group food around the clock and another only eight hours a night. On equal calories, the time-restricted mice stayed lean and avoided high blood sugar and fatty liver; the all-day group became obese.

Cancer
Aspirin cuts risk of colorectal cancer
Peter Rothwell writes in Cancer Research that trial evidence shows daily aspirin cuts recurrent colorectal adenoma risk by 17 percent and advanced adenoma by 28 percent, with about five years of use tied to a 30 to 40 percent lower risk of colorectal cancer death. Major bleeding is a risk.
Other Diseases
Could milk get you mad cow disease?
Pennsylvania confirmed chronic wasting disease in a captive doe. Media reports say no evidence shows the deer disease reaches humans, but the CDC urges hunters to avoid tissues that harbor the agent, and a Journal of Virology study raises questions about milk from cows with mad cow disease.
Obesity
Diet and Exercise Reverse Leptin Resistance, Thereby Promoting a Healthy Weigh
Mercola writes that leptin and insulin together govern metabolism and that resistance to both accompanies obesity. Research in Molecular Cell describes the leptin receptor's hinged legs locking onto leptin and signaling the enzyme Janus kinase, which researchers see as a drug target.
Heart & Blood
How to prevent or reverse coronary heart disease (I)?
The first part of a review of dietary factors in coronary heart disease: most coffee studies found no significant association, and Norwegian data tied unfiltered boiled coffee to more deaths, while each extra 10 g of daily fiber tracked with 14% fewer coronary events.
Cancer
How much vitamin d per day should I take to prevent cancer?
Michael Holick of Boston University Medical Center writes that serum 25-hydroxyvitamin D of 40 to 60 ng/mL is needed for an anticancer effect, reached by 600 to 1,000 IU a day in children and 1,500 to 2,000 IU in adults. He says most cells can convert vitamin D to its active form.
Cancer
Foods that help prevent cancer
A rundown of foods credited with lowering cancer risk: sweet potatoes, which contain DHEA; kiwi, with roughly 200 mg of vitamin C per 100 grams; pumpkin, rich in vitamins A and C and fiber; and eggplant, whose solanine and cucurbitacin have shown chemopreventive activity.
Cancer
Pomegranate prevents, antibiotic causes skin cancer - study
A case-control study in the British Journal of Dermatology confirmed UV rays as the leading skin cancer risk. It also linked ciprofloxacin use to 67 percent lower basal cell carcinoma risk, thiazide diuretics to 66 percent higher squamous cell risk, and pomegranate to lower risk of both.
Cancer
Omega 3, omega 6 fatty acids linked to breast cancer risk
Among 1,000 Mexican women with breast cancer and 1,074 controls, high omega-6 fat intake tracked with 92% higher risk in premenopausal women, while high omega-3 intake went with 42% lower risk only among obese women. No overall omega-3 association emerged.
Heart & Blood
Plant-based diet cuts risk of coronary heart disease
Plant polyphenols are the most abundant antioxidants in human diets. Ginter and Simko report that the polyphenol-rich Mediterranean diet tracks with lower coronary heart disease, as do the plant- and fish-heavy diets of Scandinavia, Switzerland and Austria.
Cancer
Eggs, chicken, red meat boost advanced prostate cancer risk
Following 27,607 men from 1994 to 2008, Harvard researchers found those eating 2.5 or more eggs a week were 81% more likely to develop lethal prostate cancer. Among men already diagnosed, heavy poultry intake tracked with 69% and red meat with 45% higher risk of lethal disease.
Cancer
Eating meat increases aggressive prostate cancer risk
In a study of 470 men with aggressive prostate cancer and 512 controls, Punnen's team tied high ground beef and processed meat intake to the disease. Grilled or barbecued and well-done meat carried the risk; rare or medium ground beef showed no association.
Heart & Blood
Walnuts help lower bad cholesterol
In an 18-person trial reported in Nutrition, Metabolism and Cardiovascular Disease, replacing 40 percent of dietary fat with walnuts for four weeks lowered LDL cholesterol 10.8 percent from baseline, against 13.4 percent for almonds and 7.3 percent for virgin olive oil.
Cancer
Drinking milk in early life linked to advanced prostate cancer - Milk Nutrition News
Tracking 8,894 Icelandic men from 1967 to 2009, J.E. Torfadottir's team found those who drank a lot of milk in adolescence were three times as likely to develop advanced prostate cancer as infrequent drinkers. Rural early residence carried 29% more risk.
Obesity
What Does It Mean to Be Fat Adapted?
Mark Sisson explains what he means by fat-adapted: a body that readily oxidizes stored fat for fuel, which he calls the normal human metabolic state. A sugar-burner, by contrast, cannot access body fat well and gets ravenously hungry hours after eating.
Cancer
Carcinogens in cooked meat linked to colorectal cancer
Comparing 413 colorectal adenoma cases with 796 controls, Zurich researchers found risk rose with intake of PhIP, MeIQx and DiMeIQx, heterocyclic amines formed in grilled, fried and roasted meat. SULT1A1 phenotype modified the MeIQx effect; other gene variants did not.
Diabetes
Curcumin supplements prevent type 2 diabetes
In a Thai trial, 240 people with prediabetes took six curcumin capsules or a placebo daily for nine months. None of the curcumin group developed type 2 diabetes, against 16% of the placebo group, and only the curcumin group lost weight.
Cancer
Dietary fiber cuts breast cancer risk
A Chinese study of 557 breast cancer cases and 536 controls found premenopausal women in the highest quartile of fiber intake were 62% less likely to have the disease, with no reduction among postmenopausal women. A review of 16 prospective studies found a 7% lower risk.
