Sugar and fats

sugar-fatSugar can be found in a lot of foods that we like the taste of but they are not necessarily good for us. Sweets, chocolate, honey, cakes and biscuits all contain too much sugar and we shouldn't eat too much of this everyday. Having too much sugar can be harmful to your teeth and cause tooth decay. Eating too much sugar can also cause you to put on weight which is bad for your health and can cause things like diabetes and heart disease.

Fats give our body energy that is stored as a fat layer under the skin to keep us warm. Too much fat will cause a bigger layer under the skin and will cause us to look bigger than we should be. Fats can also build up in your arteries, the tubes that carry your blood around your body. When this happens your brain and heart doesn't always get the amount a blood flowing that it needs and this can cause problems with your health.

food-labelFoods that have fats are butter, oil, cream, mayonnaise, ice cream, crisps, cakes and biscuits. In fact most food have some kind of fat.  The here is a food label from a cereal box. Even though we know that cereal is a carbohydrate is still contains fat. 

Saturated and unsaturated fats

It's good to have a little bit of fat in what you eat and unsaturated fat is the better to have. Saturated fat is not good for our bodies and you can find saturated fat in many foods such as butter, cheese, ice cream, biscuits and cakes. Check out the food label again. It has 6.0g of fat in this cereal. 1.3g of that is saturated fat. Check your food labels at home, how much saturated fat does your food have?
