A study in America showed that eating nuts like cashews four times a week could reduce the risk of cardiovascular and coronary heart disease by as much as 37% and that each additional serving saw a further 8% reduction in risk.
per is shown to be important in the production of enzymes associated with producing flexible blood vessel s and joints. Copper promotes the function of ling important for ysyl oxidase which plays a role in the production of collagen and elastin which are important constituents of both body components.
Calcium is widely known as being important to bones but magnesium is also important. Nearly 70% of the bodies magnesium is stored in bones. It is important because it regulates nerve activity and keeps nerve fibres healthy. Studies have shown the link between low levels of magnesium and high blood pressure and muscle spasms and just one quarter of a cup of cashew nuts contains enough calcium to prevent either conditions occurring.

Cashew Nut Kernels – Product History
Cashew nuts were originally native to the northern jungles of South America but now they are grown across many tropical climates with India as the world’s major producer.
The plant is a small evergreen tree that grows a pseudocarp fruit, the cashew apple. The cashew apple matures to have a strong sweet flavour and it is very juicy with a delicate skin which makes it unsuitable for transporting to distant markets. They are regarded as delicacies locally to where they are grown. A single cashew nut forms in a drupe under the fruit.
Cashew nuts require processing because as they are harvested they are wrapped in a caustic skin that must be removed. Once removed the resulting resin is used the production of varnishes. The roasting process requires strict control as it produces anacardic acid in the smoke and this can prove fatal if breathed in.
