Eating Nuts May Help Reduce Inflammation
Highlights
  • Nuts consumption is associated with lower levels of inflammation
  • Peanuts and tree nuts contain a number of healthful components
  • The was study published in the American Journal of Clinical Nutrition

Nuts are jam-packed with inflammation-fighting monounsaturated fat. And although they're slightly high in fat and calories, studies show snacking on nuts can actually have many health benefits and also promotes weight loss because their protein, fiber and monounsaturated fats are satisfying.

A study published in The American Journal of Clinical Nutrition in 2011 found that over a 15-year period, men and women who consumed the most nuts had a 51 percent lower risk of dying from an inflammatory disease (like RA) compared with those who ate the fewest nuts.

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, a finding that may help explain the health benefits of nuts.

Peanuts and tree nuts contain a number of healthful components including magnesium, fibre, L-arginine, antioxidants and unsaturated fatty acids such as linolenic acid.



Five or more servings of nuts per week or substituting nuts for animal proteins tied to a healthy profile of inflammatory biomarkers, the findings showed. "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 from Brigham and Women's Hospital in Boston, Massachusetts. "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.



In the current study, the research team performed a cross-sectional analysis of 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 tumour necrosis factor receptor 2 (TNFR2). After adjusting for age, medical history, lifestyle and other variables, they found that participants who had consumed five or more servings of nuts per week had lower levels of C-reactive protein and interleukin 6 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 biomarkers of inflammation, showed the study published in the American Journal of Clinical Nutrition.

According to Dr.Rupali Datta, Chief Nutritionist at SmartCooky, "They are sources of unsaturated fats, high-quality vegetable protein, fiber, minerals, tocopherols, phytosterols, and phenolic compounds. By virtue of their nutritional composition they are potent health boosters. Clinical studies across the worlds have shown the positive effect of nuts on cardiovascular risk factors, weight management and to a lesser extent on cancer, inflammation and hypertension."
