A study published online April 20, 2021, by the journal Nature Communications suggests thatgetting too little sleep in midlife increases the risk for dementia later in life. Researchers analyzed the sleep data of 8,000 middle-aged adults who were followed for 25 years. People who slept six hours per night at age 50 were 22% more likely to develop dementia, compared with people who slept seven hours. People who slept six hours per night at age 60 were 37% more likely to develop dementia, compared with people who slept seven hours. The study was observational and can’t prove causation.
Non-weight-bearing exercise takes the burden off the hips and knees and makes it easier for people with joint pain to exercise. Exercise machines that are gentle on the joints include an elliptical trainer, a stationary bike, and a rowing machine. Low-impact exercises can also provide a good cardio workout and muscle strengthening without stressing the joints. Examples include pool exercises, tai chi, and short walks at a brisk pace.
Lower leg and foot swelling is most often the result of an abnormal buildup of fluid, which doctors refer to as edema. Fluid tends to flow downhill, making it more likely to pool in the lower parts of the body. Excess fluid retention can be triggered by many things, including eating too much salt, heat, drinking alcohol, or standing for a long period of time. To reduce it, reduce dietary sodium, elevate the feet at the end of the day and wear support stockings.

Grilled meat—in particular red meat—has garnered some negative attention from nutritionists in recent years, because in addition to its less-than-stellar nutritional profile, it’s been shown to generate potentially cancer-causing compounds when cooked over high heat. On the grill, the fat and protein in the meat produces harmful, potentially carcinogenic compounds called heterocyclic amines and polycyclic aromatic hydrocarbons. Better options are lean chicken and fish, and grilled vegetables.
