Early Diners Are Healthier

A study of more than 4,000 men and women in Spain found that people who ate their evening meal before 9 p.m. or at least two hours before going to bed had a 20 percent lower risk of breast or prostate cancer than those who ate after 10 p.m. or went to bed soon after eating.

These cancers may be bolstered by disruptions to the biological clock, and meal timing impacts sleep cycles. More research needs to be done to confirm the link, but it’s worth noting that studies have already shown that eating dinner earlier can help you maintain a healthy weight and sleep better.

A Blood Test That May Warn of Alzheimer’s Sooner

The only way to catch Alzheimer’s early— allowing treatment to slow the progression of symptoms—is through expensive imaging or invasive tests. Now researchers have developed a blood test that they hope will spot the amyloid beta that forms brain plaque, a hallmark of the disease. Working with archived blood that had been collected between July 2000 and December 2002 from participants in a study of adults ages 50 to 75, they compared samples from 65 people who were later diagnosed with Alzheimer’s to more than 800 controls. The new test correctly identified those with the disease in almost 70 percent of the cases—and it would have done so as many as eight years before they received their diagnosis using the current tests.
