The oils and fat that enter your body when you eat are made up from individual molecules called fatty acids.

Fats are important for keeping you warm when it's cold outside, for storing energy, to form hormones and lubricate the surface of your body.

Some of the fats create a protective layer around the organs, and some of them carry the fat-soluble vitamins.

But know you might think, so fat is good then? Unfortunately no, and excess of fat might bring you serious problems.

The saturated fats ca be found on foods like eggs or red meat. Coconut oil also has saturated fats.

This type of fat is solid at room temperature. A diet based on saturated fats can raise the level of cholesterol and can lead to heart disease and some forms of cancer.

To keep away from danger, you must have only two red meat based meals per week. Try to eat more fish, lean poultry, vegetables, nuts or seeds.

Trans fats are created by forcing hydrogen into vegetable oils to make them more solid. If you want, take stick margarine for an example.

This is a process that modifies the structure of fatty acids that are contained in vegetable oils and make them look more like saturated fats.

Excess of saturated fats is bad, but excess of trans-fats is even worst. Try to avoid them.

Trans-fats are mostly found on pastry products, oils used for frying and processed snack foods.

Some fats are found in plants. These are called monounsaturated fats and are very healthy.

They reduce the cholesterol level and inflammation and keep the blood vessels healthy. Using these fats daily is very recommended.

Polyunsaturated fats are found in plants and fish. The best known are omega 3 and omega 6 fatty-acids. These are found in fish oil and different seed oils.

Polyunsaturated fats are healthy, but you should not consume a big quantity of them.
