Everyone needs fat in their diet. Fat is a source of energy and some of its fatty acids provide essential building blocks for the cells in the body. Fats also help the body absorb the vitamins A, D, E and K. Not all fat that is stored in the body originates from fat in the diet. It can also be produced by the body itself from carbohydrates and alcohol.
Fats are a major energy source for the body, along with carbohydrates and proteins. To achieve a healthy diet, the European Food Safety Agency (EFSA) advises that a minimum of 20 per cent and a maximum of 35 per cent of daily energy intake should come from fat (EFSA 2010). Similar recommendations are provided by the 2010 guidelines of the Food and Agriculture Organization of the United Nations (FAO-WHO 2010), which recommends that a minimum of 15 per cent and maximum of 35 per cent of the daily energy intake should come from fat.
