Avoid obesity and correct chewing of food will help with metabolic syndrome. The process of chewing not only increases energy expenditure, but also improves the functioning of the intestines.

With reference to research by Japanese scientists, the correct approach to eating food leads to an increased release of heat in the body, known as diet-induced thermogenesis (DI). .

To clarify how prolonged chewing causes this effect in the body, scientists from Waseda University (Japan) conducted an experiment that consisted of three stages.

• In the first test of volunteers asked to swallow 20 ml of liquid test food every 30 seconds.
• In the second trial, participants held the same test food in their mouth for 30 seconds without chewing, allowing them to taste it before swallowing.
• In the third trial, volunteers chewed 20 ml of the test food for 30 seconds at a frequency of once per second, and then swallowed it.

At the same time, there were no differences in hunger and satiety scores between trials. However, research has shown that energy production increases after prolonged chewing. Taste stimulation also increased blood flow in the abdominal artery and gas exchange, which in turn helped improve the motility of the upper gastrointestinal tract. obesity and metabolic syndrome. Although the difference in energy expenditure for one meal is small, the cumulative effect obtained from multiple meals every day and 365 days a year is significant,” concluded Professor Naoyuki Hayashi.
