Research Nuts are under preliminary research to assess whether their consumption may lower risk for some diseases, such as cardiovascular diseases and cancer. A 2014 review indicated that consuming one or more servings of nuts or peanut butter per day could lower the risk of ischemic heart disease, overall cardiovascular disease, stroke in women, and all-cause mortality. A 2022 umbrella review confirmed these findings and found a 22% reduction in all-cause mortality. See also References Further reading Albala, Ken (2014) Nuts A Global History. The Edible Series.
