Cashew nuts are a popular edible nut that is grown in many tropical regions around the world. The cashew nut is actually the seed of the cashew fruit, which is harvested when the fruit is ripe. Cashews are a good source of healthy fats, protein, and minerals such as copper, magnesium, and phosphorus. They also contain antioxidants and other beneficial nutrients that may help improve heart health, promote healthy digestion, and reduce inflammation in the body. Cashews are commonly eaten as a snack or used in cooking, particularly in Indian and Southeast Asian cuisines. They can be eaten raw or roasted, and are often used to make cashew butter, cashew milk, and other products.
