Consumption of nuts and legumes and risk of incident ischemic heart disease, stroke, and diabetes: a systematic review and meta-analysis

Diabetes and ischaemic heart disease are less likely to occur in individuals who regularly consumed legumes and nuts.

This study was carried out to determine the relationship between the consumption of nuts and legumes and the incidence of stroke, diabetes, and ischaemic heart disease. Researchers analyzed nutritional and clinical data extracted from 27 studies that examined 501,791 subjects and 34,562 cases of stroke, diabetes, and ischaemic heart disease.

The team of researchers observed that subjects with high dietary intake of nuts had slight chances of developing fatal and non fatal ischaemic heart disease and diabetes, but not stroke. Increased consumption of legumes was found to lower the likelihood of total ischaemic heart disease but was also not associated with stroke risk. The results of this review show that diets loaded with nuts and legumes may protect individuals against diabetes and ischaemic heart disease.
