The Benefits of Cashew Nuts

The tropical, evergreen cashew tree produces the cashew fruit and the cashew nut. We have covered the cashew fruit here.  The cashew tree is native to Brazil and was exported by the Europeans to Southeast Asia, where it is widely cultivated today. The cashew nuts are incredibly nutritious nuts that are also a great source of protein and carbohydrates. The delicious nuts are edible raw, can be roasted, powdered and added to smoothies and shakes and are used to make curries in Southeast Asian food.

Benefits of Cashew Nuts

Significant research has shown that incorporating nuts into diet leads to better heart health and reduces risk of heart attack, stroke and cardiovascular problems. This is because nut consumption lowers cholesterol levels in the body. FDA recommends a 1.5 oz serving of nuts a day and establishes its link with lowered risk of heart disease. The high amounts of magnesium present in the cashew nuts also contribute towards heart health. Magnesium aids absorption of calcium in the bones and prevention of deposition of calcium in the arteries, which means it lowers the risk of high blood pressure and the resultant strain on the heart.

2. Weight Loss

People aiming to lose weight should include nuts in their diet, as nuts are nutritious and keep you full for a longer time.
