Текст работы

All food is made up of nutrients which our bodies use. There aredifferent kinds of nutrients: carbohydrates, proteins, fats» vitamins andminerals. Different foods contain different nutrients.

Before we cut down on fat, sugar and salt, we have to know a bitmore about the kind of food these things might be in. The biggest problem comeswhen these things are hidden in other foods: biscuits, crisps, sausages, meatpies, soft drinks and so on.

The best way is to get into the habit of checking the ingredientsand nutritional value on the sides of packets although this isn't always easyto do. Another thing to know is, for example, that we do need fat to live, it'san 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. Thematter is that there are different kinds of fat. There are fats that are goodfor us and fats that are bad for us. Eating less of the bad ones and more ofthe good ones can actually help us to live longer! Bad fats are the saturatedfats, found in animal productions, like red meat, butter and cheese.

Friendly fats are the unprocessed fats found naturally in foods likenuts and seeds, olives, avocados and oily fish, including tuna.

One more thing to know is that when food is cooked, its structurechanges. It can change the vitamin and nutrient contents of food.

More and more people feel strongly about the way, their food isproduced. Nowadays so much of the basic food we eat — meat, fish, fruit andvegetables — is grown using chemicals and additives.

Although fertilizers and pesticides have greatly increased thequantity of food and helped to improve its appearance, there is a growingconcern about the effects of these chemicals in the food chain. This concernhas led to a growth in the demand for organically grown products.
