This Harvard Study utilized data from the Nurses' Health study to examine the effects of nut consumption on healthy aging in older women (50-60). Healthy aging was defined as: no chronic disease, no memory impairment, no physical disabilities, and intact mental health. Nuts in this study included peanuts, walnuts, other nuts, and peanut butter.

Key Findings

Key Findings: Authors found that there was a higher odds of healthy aging across peanuts, walnuts, and other nuts after adjusting for the age of participants. Peanut consumption was not significant after complete adjustment of confounders, but authors conclude that including peanuts, walnuts, and other nuts at midlife may improve the chances of healthy aging in women.
