Fats are often demonized by people but they provide many important functions to our body. Moreover, healthy fats not only do not harm our figure, but often take part in the process of weight loss. Complete avoidance of fats can lead to many deficiencies and a decrease in general well-being. Not only athletes should pay attention to supplementing these components, but all those who want to take care of their health. Fats have many important functions in our body, which is why we cannot neglect them. They are a rich source of energy, regulate the nervous system, participate in the processes of building muscle mass and fat loss. They have a beneficial effect on the circulatory system and brain function. They reduce the level of bad cholesterol and increase the level of good. They favorably influence the eyesight and improve immunity. Healthy fats also have a positive effect on our beauty. They inhibit free radicals, thus stopping the body's aging processes. They are well absorbed through the skin, ensuring its proper hydration and firming. Without healthy fats, we are not able to function normally. What's more, most of them are components that we are unable to synthesize ourselves and we must provide them with food or in the form of dietary supplements. There is a group of healthy fats which is indispensable to us. The most attention should be paid to the shortages of such products as: the essential unsaturated omega-3 fatty acids - the very name suggests that these fats are essential to us. Unfortunately, our body does not synthesize them on its own, which is why we have to deliver them from food. The largest amounts are found in oily fish, rapeseed oil, chia seeds or evening primrose oil. They support the work of the brain and the nervous system. They are also important in improving the body's resistance; Omega-6 and omega-9 acids - from all omega acids, only omega-9 is synthesized (in small amounts) by the human body, but only with the participation of omega-3 and omega-6. All three types of omega acids delivered in the right proportions will help us stay fit and healthy; ALA - alpha-lipoic acid, a strong antioxidant, also characterized by other health properties, among others, supports the work of the heart, regulates blood sugar, protects the eyes and liver; MCT - healthy fat, which is a great source of energy, important in maintaining the muscle mass and slimming.
