After colloidal alginic acid enters the digestive system, it encapsulates some cholesterol and other lipids, making these fats unable to be absorbed by the gastrointestinal tract. Secondly, people's digestion and absorption of fat rely on their own secretion of bile acids. The more bile acids, the more fat they absorb. Some bile acids break down fat and are reabsorbed and reused by the intestinal wall. The colloid of alginic acid diffuses on the intestinal wall, which can prevent the reabsorption of some bile acids and reduce the amount of bile acids in the digestive tract, thereby reducing the fat absorption rate. But alginic acid’s fat-reduction efforts don’t end there. When the amount of bile acids in the digestive system is insufficient, the human body will automatically send a signal to drive the liver to produce new bile acids to supplement the bile acids. The raw material for bile acid production is cholesterol in the liver.

In addition, seaweed can not only reduce fat absorption, but is also rich in minerals such as iron, copper, calcium, magnesium, vitamins and various amino acids necessary for the human body. Therefore, eating more seaweed to lose weight can also avoid malnutrition.

Seaweed also has an important function in maintaining normal blood pressure. An important reason for abnormal blood pressure is the imbalance of trace elements sodium and potassium in the human body. Since people eat salt every day, sodium will continue to enter the body, but potassium supplementation may not be sufficient and timely. Therefore, many people often suffer from an imbalance of low potassium and high sodium. The alginic acid in seaweed is actually a colloidal mixture wrapped with metal ions such as potassium, calcium, and magnesium.

After alginic acid enters the intestine, since the intestine is alkaline, it has to look for metal ions to combine with. People eat salt every day, and there are the most sodium ions in the intestine, so alginic acid combines with it in large amounts. The sodium ions bind and hold it tightly until it is excreted from the body. In this way, seaweed supplements potassium and removes sodium, so that potassium and sodium tend to be balanced in the human body.

Seaweed can help you lose weight because it contains alginic acid
