A new study published in American Journal of Clinical Nutrition showed that dietary intake of nuts is associated with lower levels of the biomarkers of inflammation. This study of than 5,000 people by the Brigham and Women’s Hospital may help to explain the documented health benefits of nuts.
Research study author Ying Bao M.D. ScD, says, “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. Our new work suggests that nuts may exert their beneficial effects in part by reducing systemic inflammation.”
For this study, the research team performed an analysis of data using dietary questionnaires, comparing the levels of the proteins known as biomarkers in blood samples collected from the study subjects. The biomarkers of inflammation that were affected were, C-reactive protein (CRP) and interleukin 6 (IL6) .
The data revealed that those who had consumed at least five servings of nuts per week had lower levels of CRP and IL6 than those who rarely or almost never ate nuts. Dr Bao says, “Much remains unknown about how our diet influences inflammation and, in turn, our risk of disease. 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.”
