Cashews are a type of nut with a soft consistency and sweet flavor.
They are native to South America, specifically Brazil, and were introduced by colonists to Africa and India. These regions are the largest producers of cashews today. Cashews are sold both raw or roasted, and salted or unsalted.
Cashews have recently been used to make dairy alternatives, such as cashew milk, cashew-based cheese and cashew-based cream sauces and sour cream.
This article is part of a collection of articles on the health benefits of popular foods.
It gives information on the nutritional value of cashews and their possible health benefits. You will also find some tips on how to include cashews in the diet and learn about any possible health risks.

A 1-ounce serving of cashews is about 18 whole cashews. Cashews are high in monounsaturated and polyunsaturated fats and a good source of protein.
Consuming a high proportion of plant-based foods appears to reduce the risk of many lifestyle-related health conditions.
The monounsaturated and polyunsaturated fatty acids found in cashews can help decrease LDL cholesterol and triglyceride levels. This reduces the risk of cardiovascular disease, stroke, and heart attack.
A study published in the British Journal of Nutrition showed that the risk of coronary heart disease may be
The U.S. Food and Drug Administration (FDA) have approved a health claim for food labels that "eating 1.5 oz per day of most nuts as part of a diet low in saturated fat and cholesterol may reduce the risk of heart disease."
Cashews are a good source of magnesium, which plays an important role in over 300 enzymatic reactions within the body.
These include the metabolism of food and synthesis of fatty acids and proteins.
Magnesium is also involved in muscle relaxation and neuromuscular transmission and activity.
People with the highest intake of magnesium were found in the Framingham Heart Study to have a

The researchers concluded that eating nuts does not lead to a weight gain, and that it may help maintain a healthy weight.

According to a study in the American Journal of Clinical Nutrition, frequent nut consumption is associated with a reduced risk of needing surgery to remove the gallbladder.
In over a million people documented over a time span of 20 years, women who consumed more than 5 ounces of nuts a week had a
Cashews are one of the few food sources that are high in copper. One ounce of cashews contains 622 micrograms of copper. For adults aged 19 years and over, the recommended intake for copper each day is 900 micrograms.
Severe copper deficiency is associated with lower bone mineral density and an increased risk of osteoporosis. More research is needed, however, on the effects of marginal copper deficiency and the potential benefits of copper supplementation for prevention and management of osteoporosis.
Copper also plays an important role in the maintenance of collagen and elastin, major structural components of our bodies. Without sufficient copper, the body cannot replace damaged connective tissue or the collagen that makes up the scaffolding for bone. This can lead to a range of problems, including joint dysfunction as bodily tissues begin to break down.
The magnesium in cashews is also important for bone formation as it helps with the assimilation of calcium into the bone. Manganese, another mineral in cashews, has been shown to
Nuts have a high-fat content, and they can become rancid. Keeping cashews in a cool, dark and dry place can improve their shelf life.
If stored properly, cashews will keep for a few months at room temperature, a year in the refrigerator or 2 years in the freezer.
Rancid nuts are not unsafe but have a sharp flavor most people find unpleasant.

Apart from plain and roasted cashews, other cashew products include cashew nut butter, cashew oil, and cashew-based beauty products. These are available for purchase online.
Cashews contain fat, but these are mostly unsaturated fats, which are healthful in moderate quantities.
Truly raw cashews are not safe to eat, as they contain a substance known as urushiol, found in poison ivy. Urushiol is toxic, and contact with it can trigger a skin reaction in some people.
Cashew kernels are often sold as "raw" in stores, but these have been steamed. This removes the toxins. These cashews are healthful.
Depending on the brand, salted and roasted cashews can contain high levels of salt and fat, which may not be healthful. It is best to check the label first and consume these nuts in small quantities.
Overall, it is better to eat a diet with variety than to concentrate on individual foods as the key to good health.
