40% of the daily energy intake of a child under 2 years should come from fat. For children older than 2 and adults this goes down to 30%. Fat provides energy and is needed for the absorption of the fat-soluble vitamins A, D, E, and K.
Some fats are essential. Essential fats are called essential because they can't be made in the body, so it's important to include them in your child's diet. The body consists of about 100 trillion cells. All cells in the body have a cell membrane. This cell membrane consists of fat and functions in a similar way to our skin. Essential fats are a part of the cell membrane to keep it flexible – they ensure that nutrients can enter the cell while waste products are transported out. These essential fats are found in breast milk, vegetable oils (e.g. sunflower oil), soft and liquid margarine (e.g. Rama). This means that nature actually provides the nutrients children need. It is important that you include these nutrients in a healthy, balanced diet throughout their childhood.
