What is the relationship between eating fruit and health

According to the latest report, scientists have found two components in apples, one is called “quercetin” and the other is called “dihydroxybenzoic acid.” Using them to treat artificially cultured brain cells, it was found that within a specific concentration range, they help to stimulate the formation of brain cells and protect the cells from extinction.

These substances come from apples, but they are completely different from “how to eat apples”. First of all, when a substance can have an impact on the human body, we must consider the issue of “quantity”. The effect of any substance on the human body is related to the quantity. For example, in this study, quercetin can promote the formation of brain cells at a certain concentration, but at a higher concentration, not only cannot promote, but greatly inhibits the formation of brain cells. If you want to get the help of these substances by eating apples, you need to consider “how many apples you can eat an effective amount, but not the harmful amount.”

In the above studies, scientists also used apple juice to do experiments, and the results had no effect on the formation of brain cells. This means that eating apples cannot achieve the effect of “promoting the formation of brain cells.”

These are just preliminary cell experiments and animal experiments. The mode of action of a substance in animals or cells cultured in vitro may be similar to that in humans, but it may also be completely different. Therefore, the results of cell experiments and animal experiments can guide scientists to better understand and understand the mechanism of action of these substances, but the results of these experiments cannot be extended to the human body.

In addition, fruit has a positive and positive effect on most people. “Eat more fruits and vegetables” is one of the basic principles of a healthy diet. However, there is some common sense that is easy to misunderstand about eating fruits.

Nutrition guides often link vegetables and fruits together, and the recommendation for “eat more” is “a catty of fruit and a catty of vegetables every day.” For health, vegetables and most fruits have similarities, such as being rich in vitamins and minerals, feeling fuller, lower in calories, and less fat. In particular, “phytochemical components” such as polyphenols are considered to be the material basis for various “health effects”.

However, delicious fruits are often high in sugar. Although the sugars in fruits are not used as “additional sugars” or “free sugars” to limit intake, they are only absorbed into the body at a lower rate than free sugars and have a relatively small impact on insulin. After being absorbed into the blood, they are “indifferent to each other” with the added sugar. The sugar content of most vegetables is very low, and there is no “black spot” in this regard.

“Half a catty of fruits and a catty of vegetables”, if you do not eat fruits and eat a catty and a half of vegetables, there is nothing wrong; but if you do not eat vegetables and eat a catty and a half of fruits, your sugar intake may be a little too much.
