In a study of more than 5,000 people, researchers have found that greater nuts consumption is associated with lower levels of biomarkers of inflammation. Five or more servings of nuts per week led to a healthy profile of inflammatory biomarkers, the findings showed.
The team of the researchers assessed diet using questionnaires and looked at the levels of certain proteins known as biomarkers in blood samples collected from the study participants.
“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 corresponding author Ying Bao.
Bao is from Brigham and Women’s Hospital in Boston, Massachusetts and performed a study on how substituting nuts for animal proteins can help in better health. “Our new work suggests that nuts may exert their beneficial effects in part by reducing systemic inflammation,” Bao noted.
Previously Bao and her colleagues observed an association between increased nut consumption and reduced risk of major chronic diseases and even death, but few prospective cohort studies had examined the link between nut intake and inflammation.
Peanuts and tree nuts contain a number of healthful components including magnesium, fibre, L-arginine, antioxidants and unsaturated fatty acids such as, linolenic acid, Bao added in the research.
