The composition of the nut is so diverse that cashews positively affect the entire human body. Cashews contain unsaturated fatty acids – Omega 3, Omega 6, and Omega 9 – which work together to support the nervous system. In addition, cashews are a great source of B vitamins and healthy minerals such as potassium, magnesium, zinc, selenium, copper, iron, and more. For example, a cashew nut contains 73% of the daily magnesium intake, which is essential for muscle contractions. If this mineral is not consumed, muscle cramps and spasms can occur in the limbs. A handful of cashews daily is the ideal amount to prevent the possibility of magnesium deficiency.
