Introduction to Raw Cashews
Raw cashews are the seeds of the cashew tree, native to Brazil and now widely cultivated in many parts of the world. They are harvested from the cashew apple, a fruit that grows on the tree, and are then processed to remove the outer shell, which contains a caustic resin. This processing step is crucial, as the resin can cause skin irritation and other health issues if ingested. Raw cashews are a good source of protein, fiber, and healthy fats, making them a popular choice among health enthusiasts and chefs alike.
Nutritional Value of Raw Cashews
Raw cashews are rich in nutrients, including vitamins, minerals, and antioxidants. They are an excellent source of magnesium, copper, and zinc, and contain a significant amount of vitamin K and folate. Raw cashews are also high in healthy fats, including oleic acid and linoleic acid, which can help lower cholesterol levels and reduce the risk of heart disease. Additionally, raw cashews contain a number of antioxidants, including flavonoids and phenolic acids, which can help protect against oxidative stress and inflammation.
