Doctors from Harvard University recommend including dark chocolate, bananas, blueberries, apples, and chili peppers in your daily diet. According to them, these foods help maintain focus and stable energy levels, Infobae reports.
Experts advise consuming dark chocolate in small portions. It contains dietary fiber, as well as flavonoids, caffeine, and theobromine—substances that promote alertness and cognitive function.
They also recommend including bananas in the diet. Thanks to their natural sugars and complex carbohydrates, bananas provide a readily available source of energy.
Doctors also suggest regularly eating blueberries, apples, and chili peppers. These foods are rich in antioxidants (particularly anthocyanins), which help improve blood circulation in the brain, support mental clarity, and enhance cognitive activity. Apples contain fiber that helps stabilize energy levels, as well as vitamin C, which strengthens the immune system.
For beverages, preference should be given to green tea and plain water.
“Green tea contains a moderate amount of caffeine and L-theanine, an amino acid that improves concentration without increasing anxiety levels. It also contains catechins, antioxidants that support cellular health and reduce the risk of chronic diseases,” Harvard experts emphasize.
