Feeding the brain
Increasing research shows that what we eat and drink definitely affects our brain as well as our body. Here are some additional brain-feeding foods to keep in mind while grocery shopping:
Whole foods. Buy nutrient-rich vegetables, fruits, and whole grains that have not been processed, as highly processed foods are often low in nutrients, rich in calories, and high in fat and sugar. They are also more likely to contain preservatives and additives such as chemicals and dyes that can hurt brain health.
Low-sugar items. Remember that many types of cocoa and chocolate products are often high in sugar and can worsen health over time. The products used in this study were rich in flavanols, which are plant chemicals with health-giving properties. High blood sugar has been linked to poor health in general and to poor brain health. Just as excess sugar is bad for the rest of the body it also hurts the brain. Eating low or no sugar foods and saving sugary treats for special occasions may help preserve brain function.
Power nutrients. Specific nutrients such as omega-3 fatty acids have been linked to better brain health for the young and the old. Fatty fish, such as salmon and mackerel, is a good source of omega-3s. In addition, the study authors comment that the B vitamins, vitamins D and E, and choline, have also been linked to improved brain function. But it is important to remember that any one particular nutrient or food by itself won’t fully protect your brain. It’s eating a balanced diet with a variety of nutrients that may help protect your memory in the long run.
