Nuts
Various studies show that eating nuts regularly can improve heart-health markers, and a well-functioning heart is linked to having a healthy brain. A study showed that people who eat nuts regularly are less likely to develop cognitive disabilities.
A 2014 study also showed that women who are nuts regularly for several years developed a sharper memory than those who did not eat nuts at all. Nuts contain many nutrients, such as vitamin E, antioxidants, healthy fats, and many more. This explains why they are essential in maintaining good brain health.
Vitamin E protects cells against free-radical damage to reduce and treat mental decline. Walnuts contain anti-inflammatory omega-3 fatty acids, which are more helpful in maintaining good brain health.
