Before we cut down on fat, sugar and salt, we have to know a bit more about the kind of food these things might be in. The biggest problem comes when these things are hidden in other foods: biscuits, crisps, sausages, meat pies, soft drinks and so on. The best way is to get into the habit of checking the ingredients and nutritional value on the sides of packets although this isn't always easy to do. Another thing to know is, for example, that we do need fat to live, it's an essential part of our diet and physically we couldn't exist without it. But we all know that to eat much fat is bad for our health. The matter is that there are different kinds of fat. There are fats that are good for us and fats that are bad for us. Eating less of the bad ones and more of the good ones can actually help us to live longer! Bad fats are the saturated fats, found in animal productions, like red meat, butter and cheese.
