They are also primates. Why can monkeys only live by eating fruits? People can't?

Monkeys are omnivores. Most monkeys can survive eating fruit, but not humans, because humans will also have great pressure in their lives. If comprehensive nutrition cannot be supplemented, their various functions will decline, which will lead to some diseases. In fact, eating fruit can also survive, but eating only fruit for a long time can easily lead to malnutrition, because human beings need to think about many problems with their brains, and only by maintaining enough energy and nutrition can their brains work normally. Monkeys are relatively free in life. They usually just eat and play, so they don't need to think about anything, so eating fruit won't affect their health.

The digestive systems of humans and monkeys are also very different. With the improvement of living standards, if you only eat fruit, you can't meet the needs of your body. Only by eating some meat, whole grains and other foods in moderation can you feel full and have more energy in your body. Most of the substances in fruits are carbohydrates, and water, vitamins and cellulose are easily decomposed by the stomach and intestines.

After monkeys eat these fruits, their digestion speed is relatively slow, so even if they only eat fruits, they will not be hungry at all. People's digestive system is better than that of monkeys, and they can digest all kinds of food. Only a reasonable diet can keep you healthy, so you can't just eat fruit.

The structure of human body is very different from that of monkeys. People can survive by eating fruit, but this way of eating is not particularly healthy. In fact, monkeys not only eat fruits, but also eat other foods, such as nuts. There are also some differences in the diet of monkeys in different regions. Some monkeys prefer to eat plants, and some monkeys prefer to eat meat, so neither monkeys nor humans will choose to eat only fruits.
