We Are What We Eat
Choosing what to eat is no longer as easy as it once was．Our eating habits have changed, as has our way of life, and the fuel we need for our bodies is also different．Traditional diets often have too much fat and too many calories for the 21st century person．If we want to keep up with the high pace of modern life, we had better learn to make the right choices about what and how we eat．
Stores offer all kinds of food and snacks and we have to make many choices．When we choose what to buy and eat, we had better think whether the food will give us the nutrients we need．Some nutrients help build our body and make it stronger．Protein, for example, is good for our muscles．Fish, meat and beans contain a lot of protein．Calcium, which is found in eggs, milk and other dairy products, is good for our bones and teeth．We should also eat carbohydrates, the main fuel for our body, which we can get from bread, rice and noodles．Other nutrients, such as fiber and minerals, help keep our body functioning well．Vitamins, which we can get from eating vegetables, fruit, fish and drinking milk, help our body fight disease．?
But the choices we make are not just about nutrition．Many people today make choices about their eating habits based on what they believe．Eating habits become part of who we are．Some people become vegetarians because they believe it is healthier not to eat meat or because they think we should not kill animals for food．Others become vegans and will not eat any animal products at all, not even eggs．We also make choices based on how the products are grown or made：environmentally friendly food, or “ecofood”, is produced by companies who have tried to use green and clean ways to grow it．Organic vegetables are those that are grown without chemicals that can be harmful to human beings or the environment．
Because we have so much to choose from, many companies and stores offer advice about what we should eat．Books, magazines and television shows tell us about food and pills we should buy to become smarter, healthier and more beautiful．It is probably better, however, if we spend our time and money on buying good food and keeping a balanced diet．If we eat healthy food in the right amounts, we do not have to buy any supplements．The same goes for “crash diets” that some companies say will make us lose weight fast．Instead of eating expensive diet foods or going on healthy diets, we can simply try to eat less fat and sugar and exercise more．
The best way to make sure that we will feel and look fine is to develop healthy eating habits．We ought to learn more about our body and the fuel it needs to keep fit．Only in that way will we be ready for the challenges and opportunities in life．
