Keep your bedroom dark.
Research shows exposure to light at night may increase the risk of ovarian and breast cancer in women. Light suppresses the normal production of melatonin, the brain chemical that regulates our sleep-wake cycles, which could increase the release of estrogen-fueled cancer. A study showed breast cancer risk was increased among women who didn’t sleep during the times when their melatonin levels were highest.
Eat less high-fat animal protein.
After tracking food choices of more than 121,000 adults for up to 28 years, Harvard researchers found that people who ate three ounces of red meat every day were about 13 percent more likely to die—often from heart disease or cancer—before the study ended than people who didn’t eat meat. A Yale study found that women who ate the most animal protein had a 70 percent higher risk of developing non-Hodgkin’s lymphoma, while those who ate diets high in saturated fat increased their risk 90 percent. Switch to low-fat or nonfat dairy, choose poultry or fish instead of beef or pork, and use olive oil instead of butter.
Snack on red grapes.
They’re great sources of resveratrol, an antioxidant that may slow cancer growth in the lymph nodes, stomach, breasts, and liver. A 2011 study from The University of Texas Health Science Center found that resveratrol inhibited skin damage that ultimately leads to skin cancer. Although all grape skins contain resveratrol, red and purple grapes have the most.
