Disease Prevention


One of the most impactful measures in research is mortality, or death rate. When certain behaviors or practices are positively or negatively linked to mortality, it signifies that they may or may not want to be continued. For example, smoking is associated with death from certain cancers.

Dietary factors have also been shown to have effects on mortality. In fact, in several population groups (whites, blacks, and the elderly), studies have shown that as frequency of eating nuts such as peanuts increases, mortality from all causes is reduced (Fraser, 1997). The reduction has been shown to be as much as over 40% in those who consume a small amount of peanuts more than five times per week compared with those eating them infrequently.

Deaths due to heart diseases like cardiovascular disease and coronary heart disease have shown strong, consistent reductions with increasing nut/peanut and peanut butter consumption in the Iowa Women’s Health Study for example (Kushi, 1996). And in a study of Seventh-day Adventists in California, it was found that frequency of nut/peanut consumption had a highly significant inverse association with death from Ischemic Heart Disease (Fraser, 1992).

Who would have thought that while enjoying the flavor of peanuts and peanut butter we could also be promoting our longevity?
