No Indian meal is ever complete without something fried: especially if you’re going the whole hog in your eating habits. The occasional samosa from the canteen, the burgers you indulge in on the way home, a packet of fried chips or fritters: they’re all made out of oil that isn’t necessarily the best for your health and longevity. Although the best is to avoid fried food in a way that you only eat them minimally, it is useful to ensure that your consumption of fried food is food that is crafted out of a healthy oil. Here are a couple of oils that are useful for you health wise:
– Olive Oil: A derivative of the olive fruit, olive oil is perfect for cooking – especially because of the quality monounsaturated and polyunsaturated content. It is also rich in vitamins E and K, and is perhaps one of the most heart-friendly oils in the world.
– Coconut Oil: Coconut Oil comprises medium-chain triglycerides, which are more often effectively used by the body as a source of energy than the low-chain triglycerides are. This automatically means that they have a smaller chance of being stored in the body as fatty tissue. Coconut oil is rich in these medium chain triglycerides and therefore, helps promote fat loss effectively.
– Groundnut Oil: Rich in the good kind of fat, i.e., the line of monounsaturated and polyunsaturated fats, Groundnut oil also has a longer shelf life in comparison with other cooking oils. Since it has a rather high smoke point, it is less likely to impinge on your heart’s health. Groundnut oil is rich in nutrients as well, and does not affect the bad cholesterol levels adversely.
– Sunflower Oil: Sunflower oil comes in with a very rich and oleic value, which helps tremendously because it means that the oil is rich in monounsaturated fats resources. It has absolutely no harmful trans fat. Since it is rather mild and has a lot of vitamin E content and antioxidants, sunflower oil is actually a dose of goodness ingested with every bite.
– Soybean Oil: Soya bean or Soybean Oil is the very essence of the nutrition in the soya bean – therefore, it is rich in the antioxidants and all the mineral wealth that soya beans are associated with. It is rich in Omega-3 fatty acids and polyunsaturated fats, and has a high oleic content, which ensures that the oil is good for heart health.
– Canola Oil: Canola Oil is an extract of mustard seed or rape seed, and is one of the best oils for the heart and its health. It works perfectly for deep-frying needs, and is rich in oleic content as well.
