Nutrition research has known for quite some time now that adding nuts to our menus can reduce the risk of cardiovascular diseases. Some conclusive studies focus on cashew nuts and their positive effects on our health in particular. An Indian study conducted in 2018 concentrated on the effects of cashew nuts in patients with type 2 diabetes mellitus. In the course of the study, 300 type 2 diabetes patients were divided into two groups. The participants were obese, between 41 and 60 years of age, and 55% were men. One group – the control group – received an average diet for 12 weeks. The other group subsisted on a similar diet for the same period of time, however, this diet included 30g of cashew nuts a day. The result: The systolic blood pressure in participants from the cashew nut group was lower than in participants in the control group. At the same time, persons who consumed cashew nuts every day showed an increase in HDL cholesterol levels compared to the control group. HDL cholesterol is also known as the “good cholesterol”. This is because it transports cholesterol from our cells to our liver, which breaks down blood fat. In doing so, the HDL cholesterol protects us against arteriosclerosis. The study did not show any other effects, for example on body weight, insulin levels or other blood values. Summary: In patients with type 2 diabetes mellitus, daily consumption of cashew nuts can reduce systolic blood pressure and increase HDL cholesterol levels.
