Eating nuts will lower inflammation in your body, says a new study of more than 5,000 people. Researchers from Brigham and Women's Hospital found that people who had a higher intake of nuts had lower levels of biomarkers for inflammation.


"Population studies have consistently supported a protective role of nuts against cardiometabolic disorders such as cardiovascular disease and Type 2 diabetes, and we know that inflammation is a key process in the development of these diseases," said study author Ying Bao, M.D. "Our new work suggests that nuts may exert their beneficial effects in part by reducing systemic inflammation."


Previous research by Bao and her colleagues found an association between increased nut consumption and reduced risk of major chronic diseases and even death, but few studies had examined the link between nut intake and inflammation.


The current study used data from the Nurses' Health Study, which includes more than 120,000 female registered nurses, and from the Health Professionals Follow-Up Study, which includes more than 50,000 male health professionals.


The team assessed diet using questionnaires, and looked at the levels of certain telltale proteins known as biomarkers in blood samples collected from the study participants. They measured three well-established biomarkers of inflammation: C-reactive protein (CRP), interleukin 6 (IL6) and tumor necrosis factor receptor 2 (TNFR2).


They found that participants who had consumed five or more servings of nuts per week had lower levels of CRP and IL6 than those who never or almost never ate nuts. In addition, people who substituted three servings per week of nuts in place of red meat, processed meat, eggs or refined grains had significantly lower levels of CRP and IL6.


Tree nuts and peanuts contain numerous healthy components including magnesium, fiber, L-arginine, antioxidants and unsaturated fatty acids such as α-linolenic acid. Researchers don't know which components protect against inflammation or if the anti-inflammation benefit may be due to a combination of all of them.


"Much remains unknown about how our diet influences inflammation and, in turn, our risk of disease," said Bao. "But our study supports an overall healthful role for nuts in the diet and suggests reducing inflammation as a potential mechanism that may help explain the benefits of nuts on cardiometabolic diseases."


The study was published in the American Journal of Clinical Nutrition.
