Mental and social engagement can help keep your brain sharp and lower the chances of cognitive decline, in part because challenging our brains may help forge new connections between brain cells. The key to taking advantage of the brain’s malleability is to find activities that you truly enjoy and to commit to life-long learning.
Can a Mediterranean-type diet with extra servings of nuts and extra-virgin olive oil help protect memory and thinking skills with age? A study in this week’s JAMA Internal Medicine suggests that it might. The findings come from a small substudy done as part of the PREDIMED trial, which showed that a Mediterranean diet supplemented with extra-virgin olive oil or nuts reduced heart attacks, strokes, and other cardiovascular problems among people at high risk for them. Although the results of the new PREDIMED study are promising, its small size and the fact that it wasn’t designed to look at connections between diet and brain health mean the results need to be taken with a grain of salt. That said, since there’s no downside to following a Mediterranean diet, an added bonus beyond great taste could be protecting memory and thinking skills.
A study published in this month’s Journal of Nutrition suggests that drinking caffeinated beverages, having the occasional alcoholic drink, and eating a healthy diet may help preserve memory and thinking skills long into old age. In particular, foods that are part of the Mediterranean diet—fruits, vegetables, nuts, fish, olive oil, and whole grains—show promise for preserving memory and preventing Alzheimer’s and other forms of dementia.
