It is no longer as easy as it once was to choose what to eat. Our eating habits have changed, so has our way of life, and what we need for our bodies is also different. Traditional diets often have too much fat. So we had better learn to make the right choices about what and how we eat.
When we choose what to buy and eat, we had better think whether the food will give us thenutrientswe need. Some nutrients help build our bodies and make us stronger. We eat fish, meat and beans because the nutrient in them is good for our muscles. We choose eggs, milk and other dairy products (奶制品), which are good for our bones and teeth. We eat bread, rice and noodles to get carbohydrates (糖类) from them. We choose vegetables and fruit to get vitamins, fiber and minerals.
But the choices we make are not just about nutrition (营养). Many people today choose what to eat according to their beliefs. Some people become vegetarians (素食主义者) because they believe it is healthier not to eat meat or they think we should not kill animals for food.
