But what should I do if I can't control my mouth?

Merchant for quasi -business opportunities, a "white kidney bean extract"

Carbo water blocking product

Appears on the e -commerce platform,

It was even labeled with the "weight loss artifact".

Can carbohydrate blocking agents really make us lose weight?

Carbo water blocking agent is invalid for sugars

The reporter searched on the e -commerce platform with the keywords of "carbohydrate blocking agent" and found that the carbohydal blocking agent took white kidney bean extract as the main ingredient.

Many manufacturers claim that taking it before eating the staple food can block the absorption of high -carbohydrates and help stabilize blood sugar.

Wang Wen, a nutritional physician of the Nutrition Department of Henan Provincial People's Hospital, said that the actual role in the extraction of white kidney beans is α-amylase inhibitors (α-AI).

Gastrointestinal starch requires salivary amylase and pancreatic amylase, while α-AI can inhibit the activity of salivary amylase and pancreatic amylase, and play a role in preventing starch from decomposing absorption.

Although theoretically α-AI can prevent the human body from absorbing starch, how much activity can α-AI retain after gastric acid reactions, and it is unknown how many starch can be prevented from digesting and absorption.

It is worth noting that for many people, starch is not the main part of the diet. The "culprit" that allows us to gain weight is the various sugar added to the fine processing foods, such as sucrose, fructose, glucose, etc.

The human body does not require amylase to absorb these sugar, so carbohydrates are useless. Even if you take carbohydrates, you ca n’t eat cakes, ice cream, and sweet drinks.

People with diarrhea need to take carbohydrates carefully

What is the safety of carbohydrate blocking agents? Wang Wen introduced that α-AI is a pure natural biological active substance. After entering the human body, it will be discharged through the gastrointestinal tract into the body without entering the blood circulation system.

At present, there are no reports of serious side effects in clinical research on α-AI. It can be used as ordinary food and can also be added in dietary supplements and beverages.

Generally speaking, the daily intake of carbohydrate blocking agent not exceeding 10 grams is safe. There are then symptoms such as anemia and syncope.

However, taking amylase inhibitors may cause intestinal problems such as flatulence and diarrhea. People who are prone to flatulence and diarrhea should be used with caution.

Persistent people who are mainly starch, very fat, and large amount of food for carbohydrates may have a bit effective, but lack rigorous scientific experimental argument.

In general, it is not scientific to lose weight by relying on carbohydrates to lose weight, because what really makes us gain weight is white sugar, fructose syrup, oil, etc., and carbohydrates do not prevent the human body from absorbing them. The most The scientific way of weight loss is to adjust the diet structure and perform a scientific movement.
