Introduction to Cashew Nuts
Cashew nuts are the seeds of the cashew tree (Anacardium occidentale), native to Brazil and now widely cultivated in many tropical countries. They are rich in nutrients, including healthy fats, proteins, and minerals like magnesium and zinc. Cashews are also a good source of antioxidants, which can help protect against cell damage and reduce the risk of chronic diseases. With their creamy texture and sweet, nutty flavor, it’s no wonder why cashews are a favorite among snackers and chefs alike.
Nutritional Value and Health Benefits
Before diving into the shelf life and storage of cashew nuts, it’s essential to appreciate their nutritional value and health benefits. Cashews are a nutrient-dense food, providing a range of essential vitamins and minerals. They are also low in carbohydrates and rich in healthy fats, making them a popular choice for those following a low-carb or keto diet. Some of the key health benefits associated with cashew consumption include:
Improved heart health due to their high levels of monounsaturated and polyunsaturated fats
