Researchers from the New York State Institute for Basic Research in Developmental Disabilities investigated in this field and suggested that a diet supplemented with walnuts (1-2 oz per day) may help reduce oxidative stress by decreasing the generation of free radicals and by boosting antioxidant defense.
Also, evidence from animal and human studies suggests that dietary consumption of walnuts may help improve cognitive function (brain health) and may also reduce the risk of other diseases, such as cardiovascular disease, depression and type 2 diabetes, which are risk factors for the development of dementia.
