How are vegetables and fruits distinguished?
Difference:

First, the definition is different.

A vegetable refers to a plant or fungus that can be cooked into food. Vegetables are one of the essential foods in people's daily diet.

Fruit refers to the fleshy and edible plant fruit, and its main taste is sweet and sour. Fruit is not only nutritious, but also promotes digestion.

Second, the nutrients are different.

The nutritional components of vegetables mainly include minerals, vitamins, fiber and so on. The higher the content of these substances, the higher the nutritional value of vegetables. In addition, the content of water and dietary fiber in vegetables is also an important nutritional quality index.

Kiwifruit, fresh jujube, strawberry, loquat, orange, orange, persimmon and blueberry are rich in vitamin C. Based on the vitamin C content of 100g fruit, kiwifruit contains 420mg, fresh jujube contains 380mg, strawberry contains 80mg, orange contains 49mg, loquat contains 36mg, and orange and persimmon contain 30mg each. Bananas and peaches each contain 10 mg, grapes, figs and apples each contain only 5 mg, and pears only contain 4 mg.

Third, fructose is different.

Fruits are rich in fructose, and their calorie function far exceeds that of vegetables, so eating the same amount of fruits and vegetables will make fruits more likely to promote obesity and overweight. Patients with diabetes and obesity should strictly control the consumption of fruits, while vegetables are relatively safer.

Fourth, the acidity and alkalinity are different.

Compared with fruits, vegetables are alkaline foods, which can more effectively regulate the internal environment balance, relieve fatigue and expel toxins. Because fruit contains tannic acid, the effect of regulating human internal environment is even worse.

Extended data:

If the content of acid, citric acid, malic acid, tartaric acid and other organic acids in fruits is richer than that in vegetables, it can stimulate the secretion of digestive glands, stimulate appetite and be beneficial to the digestion of food.

Some fruits are also rich in dietary fiber, especially pectin, which can increase intestinal peristalsis.

Fruit also contains phytochemicals such as flavonoids, aromatic substances and coumarin, which have special biological activities and are beneficial to human health.

Generally speaking, there are more carbohydrates, organic acids and aromatic substances in fruits than fresh vegetables, and vegetables cannot replace fruits. The contents of vitamins, dietary fiber, minerals and phytochemicals in vegetables are higher than those in fruits, so fruits cannot replace vegetables.
