Nuts: Consumption Causes Less Weight Gain?
In a latest study, researchers have assessed the associations between changes in total consumption of nuts, intakes of specific types of nuts and weight change during more than 20 years of follow-up in US men and women from three prospective cohort studies. It was found that Increased total consumption of nuts and any type of nuts (including peanuts) was associated with less long-term weight gain and lower risk of developing obesity.

Obesity is a significant contributor to increased morbidity and mortality. Primary prevention of gradual weight gain may be an effective strategy to reduce the prevalence of obesity at the population level, however, identifying the underlying causes of the subtle increases in body weight has been challenging.

The findings provide further support to existing evidence by demonstrating that increasing the total consumption of nuts, by 0.5 servings/day, was associated with a lower risk of moderate weight gain and a lower risk of developing obesity. The magnitude of inverse associations with obesity risk was similar between specific types of nuts.

The mechanisms underlying the observed associations between increasing nut intake and lower risks of weight gain are multipronged. The high fibre content of nuts can delay gastric emptying, increase satiety, suppress hunger and the desire to eat, and promote fullness. The fibre in nuts also provides a greater binding of fatty acids in the gut, leading to greater calorie fecal excretion.
