Walnut Consumption Associated with Greater Life Expectancy in US Adults

Walnut Consumption Associated with Greater Life Expectancy in US Adults


A study recently published in the journal Nutrients aimed to examine how consuming walnuts affect mortality and estimated life expectancy. 


Researchers from Harvard found that including walnuts in the diet was positively associated with lower mortality and those who consumed more than 5 servings of walnuts a week saw a greater life expectancy.

The study was conducted using US adults from the Nurses’ Health Study and the Health Professionals Follow-up Study. In total, 67,014 women and 26,326 men were included in the research. Using statistical analysis, the authors analyzed total mortality across various categories of walnut intake, ranging from less than 1 serving per week to more than 5 servings per week. They found that higher consumption of walnuts was associated with a lower risk of total and cardiovascular disease mortality. Moreover, a greater life expectancy at age 60 was observed in those who consumed walnuts more than five servings a week, compared to non-consumers.
