Translation:
Many animals can distinguish their food because they can see him, and so can humans. When you see an apple or a piece of chocolate, you know that these things are edible. Of course, you can also choose food according to other senses. You may like a kind of food because it tastes good. This is invisible, but it smells good and tastes good. Different animals choose food according to different senses. A few animals choose food through only one sense, while most animals rely on multiple senses.
Although there are many kinds of food, some animals only eat one kind of food all their lives. For example, the giant panda only eats one kind of bamboo in his life. When you give other animals many choices, they will only choose one food. There is a kind of white butterfly that only stays on Chinese cabbage, although there are many other vegetables in the field. More animals have more than one eating habit. For example, bears eat fruits and fish, and foxes eat small animals, birds and fruits. These diets will change according to different seasons.
Humans usually have their own eating habits. We usually eat food not because it is good for our health, but because we like it. In France and Britain, people usually eat foods with high sugar content, which makes them overweight and harmful to their health. Eating too much red meat and animal products is also harmful to your health. Therefore, choosing the right food has now become a field of knowledge.
