Fat is a source of fatty acids and our body cannot make fat itself. Rather we have to supply fats to our body through our foods. A certain amount of fats is essential to maintain a healthy diet. Because we need fat to absorb other nutrients like vitamin A, vitamin D, and vitamin E. As these vitamins are fat-soluble, they cannot be absorbed without the help of fats.
However, the unused fats likewise unused carbohydrates and protein can be turned into our body fat. So, we have to be concerned so that we may not consume extra fats. We have to take a certain amount of fats that our body cells can use to absorb vitamins. All types of fats are high in energy. One gram of fat can provide us 9kcal (37kJ) of energy. Whether it is saturated or unsaturated fats, all are a good source of energy.
Most of the foods and oil we use during our daily cooking contain both saturated and unsaturated fats in different proportions. But to maintain a healthy diet, we need to cut down those types of foods and drinks that are rich in saturated fats and trans fats. Alternatively, we can replace saturated fats with unsaturated fats.
At first, we have to know the source of saturated fats. All kinds of butter, cheese, savory snacks are the main source of saturated fats. Trans fat is another kind of fat that is naturally found in red meat and dairy products at a low level.
Most of the experts recommend replacing all kinds of saturated fats with some unsaturated fats. Unsaturated fats are mostly available in plants and fish. These unsaturated fats can be helpful to lower our cholesterol levels. Thus, these can protect us from heart diseases.
