Researchers in the Netherlands have found a link between peanut consumption and longevity. Over 120,000 participated in the study, which has been published in the International Journal of Epidemiology. Researchers examined the overall health of people between 55 and 69 years of age and found that those eating around ten grams (about a handful) of peanuts or tree nuts had a lower incidence of cancer, diabetes, and cardiovascular disease.
It’s important to note that the study did not show causation: other lifestyle factors may be a contributing factor.
Sadly, this does not give me free reign to increase my consumption of peanut butter (my favourite food) because apparently peanut butter did not have the same positive health effect, possibly because of other ingredients like shortening and sugar which would counter the health benefits.
So, can nuts increase your life span? I’d say it’s worth integrating nuts and peanuts into your diet (as long as you’re not allergic) and you can’t go wrong. Especially if you’re substituting nuts for less healthy snack foods.
