Nuts
Eating nuts has been proven in studies to boost heart-health indices, and having a healthy heart is connected to having a healthy brain. According to one study, frequent eating of nuts may be associated with a decreased risk of cognitive deterioration in older persons. Another 2014 study discovered that women who ate nuts on a regular basis for several years had a stronger memory than those who did not consume nuts.
Nuts' favorable impacts on brain health may be explained by several elements, including healthy fats, antioxidants, and vitamin E. Vitamin E protects cells from free radical damage, which helps to delay mental deterioration. While all nuts are beneficial to the brain, walnuts may have an advantage since they also contain anti-inflammatory omega-3 fatty acids.
