The health benefits of cashews include a healthy heart, strong nerve and muscle function, aid in the formation of red blood cells, and an improved bone and oral health. They also provide relief from diabetes, anemia, and gallstones. By offering an antioxidant defense, they also encourage a better immune system. Although cashews are one of the lowest-fiber nuts, they are packed with vitamins, minerals and antioxidants. These include vitamins E, K, and B6, along with minerals like copper, phosphorus, zinc, magnesium, iron, and selenium, all of which are important for maintaining good bodily function.
