Researchers from Vanderbilt University and the Shanghai Cancer Institute examined nut intake for people from different ethnic groups and lower-income households. As peanuts (which are actually legumes) are rich in nutrients and are inexpensive to buy, they could be a cost-effective way to improve cardiovascular health, reports Science Daily. “In our study, we found that peanut consumption was associated with reduced total mortality and cardiovascular disease mortality in a predominantly low-income black and white population in the U.S., and among Chinese men and women living in Shanghai,” said author of the study, Xiao-Ou Shu. Previous studies have linked eating nuts to a lower mortality but had generally focused on higher-income, white populations. Researchers claim the new study published in the journal _JAMA Internal Medicine_ is the first to discover all races could potentially benefit from eating nuts. They examined three large groups involving more than 70,000 black and white men and women living in the U.S. and more than 130,000 men and women living in Shanghai. The results found that those who ate peanuts across all three groups had improved total mortality and less cardiovascular disease. But scientists warn that the study was based on observational data collected from questionnaires, rather than clinical trials, so they cannot determine whether peanuts are specifically responsible for a lower risk of death. “The findings from this new study, however, reinforce earlier research suggesting health benefits from eating nuts, and thus are quite encouraging,” said William Blot, co-author of the study. While peanuts may be linked to better cardiovascular health, experts caution against eating too many, especially salted nuts, as they are high in calories. Researchers say a small handful of nuts could be beneficial if eaten as part of a well-balanced diet. \[[_Science Daily_](http://www.sciencedaily.com/releases/2015/03/150302121617.htm)\] ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3729536/peanuts-cardiovascular-health-heart-attacks-strokes/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3729536/peanuts-cardiovascular-health-heart-attacks-strokes/"},"headline":"Eating Peanuts May Be a Low-Cost Way to Improve Your Cardiovascular Health","datePublished":"2015-03-03T03:27:57.000Z","dateModified":"2026-02-22T04:51:24.363Z","description":"But don’t go nuts","url":"https://time.com/3729536/peanuts-cardiovascular-health-heart-attacks-strokes/","keywords":["Research","Death","study","Peanuts","cardiovascular disease","heart attacks","nuts"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt6f4c5e55265f8e6b/698781c43c1639896a4520c0/peanuts-study-lower-deaths.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Helen Regan","jobTitle":null,"url":"https://time.com/author/helen-regan/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt6f4c5e55265f8e6b/698781c43c1639896a4520c0/peanuts-study-lower-deaths.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Closed Up Image of a Black-colored Plate Filled With Peanuts.","caption":"Closed Up Image of a Black-colored Plate Filled With Peanuts.","creditText":"DAJ—Amana Images RF/Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/research/","name":"Research"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3729536/peanuts-cardiovascular-health-heart-attacks-strokes/","name":"Eating Peanuts May Be a Low-Cost Way to Improve Your Cardiovascular Health"}}]}] ```
