Cashews are a good source of healthy dietary fats, which are essential for our body to absorb the fat-soluble vitamins (vitamin A, D, E, and K) and produce fatty acids that are vital for the development of the brain and blood clotting. These healthy fats include monounsaturated fats (MUFA) and polyunsaturated fats (PUFA). They are good for the heart and help reduce bad cholesterol (LDL cholesterol) if consumed in appropriate amounts, even in diabetics.
LDL cholesterol can rise as a result of excessive consumption of saturated fats, posing a major threat to people suffering from diseases like atherosclerosis (aka hardening of arteries). Studies have demonstrated that choosing unsaturated fats over saturated fats enhances the levels of HDL cholesterol, reduces triglyceride levels, and beneficially lowers the as well. The inclusion of nuts such as cashews, fish, and vegetable oils like olive oil and canola oil in the diet can provide these healthy unsaturated fats to the body.

Healthy Muscles & Nerves

Magnesium helps maintain blood pressure, boost immunity, maintain nerve function, and keep the bones strong.

Cashews are rich in copper, which helps in the metabolism of iron, aiding in the formation of red blood cells (RBC), and helping to keep the bones and immune system healthy. It is also vital for the nervous and skeletal system of the body. A deficiency of copper in the body may result in osteoporosis, irregular heartbeats, and anemia.
Boost Bone & Oral Health
Cashews provide phosphorus, which is essential for the healthy development of teeth and bones. Phosphorus also aids in protein synthesis, absorption of carbohydrates and fats, and the maintenance of cellular health.
Reduces Risk of Anemia
Cashews are a source of dietary iron which is vital for carrying oxygen around the body and aids in the functioning of enzymes and the immune system. A deficiency of iron in the diet can lead to fatigue, anemia, and increased susceptibility to infections.
