There are benefits.

For healthy people, there is no time limit for eating fruits, as long as you ensure a reasonable intake. According to the amount recommended by the Chinese Nutrition Society, adults should eat 200 to 400 grams of fruits per day, equivalent to one or two medium-sized apples.

However, for those who need to control their weight, high blood pressure and high blood cholesterol, consuming fruits before meals can provide a large amount of dietary fiber and potassium, while also reducing the intake of regular meals. Conversely, those who are thin and malnourished may have their appetite for the main meal affected if they eat a lot of fruit before meals.

Expanded Information:

The starting point of advocating eating some fruit for breakfast is good, but the argument that eating in the morning is more nutritious than eating in the evening doesn't make sense. This is because the human body's ability to digest and absorb and eating time does not have much to do. Digestion and absorption are mainly related to the secretion of digestive juices and the ability of gastrointestinal peristalsis.

That is to say, whether it is in the morning or at night, there is actually no difference in the absorption of fruit by the digestive system. On the contrary, compared with meat, alcohol, etc., fruit is lighter, easier to digest, very suitable for the evening food, and will not cause harm to the body.

There are also people who worry that eating fruit on an empty stomach is not good and must be eaten after meals, mainly because they are afraid that the acidity and sweetness of the fruit will stimulate the stomach to secrete too much acid, or they are worried that other substances in the fruit will combine with the stomach acid to produce stones.

In fact, for people with excessive gastric acid secretion, eating fruits with high acidity on an empty stomach may be harmful, and at the same time, fruits that are too astringent (mainly with too much tannin), such as persimmons, eating on an empty stomach may have an effect on the mucus proteins in the stomach and lead to discomfort. But for the vast majority of fruits such as apples, pears, peaches, watermelon, oranges and strawberries, eating them on an empty stomach is not a problem.
