The Japanese Phenomenon of Betsubara: Why There is Always Room for Dessert.

According to ТСН: After a hearty lunch, when there is almost no room left in the stomach, the suggestion to indulge in dessert brings positive emotions. This interesting phenomenon in Japanese culture even has a name - 'betsubara', which means 'separate stomach'.

The stomach is an elastic organ capable of adjusting to the amount of food. When a person begins to eat, a process called 'gastric accommodation' occurs, during which the smooth muscles relax, allowing the stomach to stretch without significant pressure.

The consistency of food also plays an important role. Heavy main dishes, such as meat and side dishes, require a long time to digest, which can cause a feeling of heaviness. In contrast, desserts like mousses, ice cream, or cream cakes are usually light and consist of simple carbohydrates. They leave the stomach faster, creating the sensation that there is 'room for them'.

The Brain and the Desire to Indulge

The desire to eat sweets arises not in the stomach, but in the brain. There is a term 'hedonistic hunger' - the desire to eat for pleasure rather than energy replenishment. Sugar activates the mesolimbic system of the brain, stimulating the release of dopamine, which temporarily blocks satiety signals for enjoyment.

Another mechanism is 'sensory-specific satiety'. When one eats monotonous food, the brain loses interest in it. The introduction of a new taste - sweet or sour - 'refreshes' the reward system, boosting appetite.

Time and the Sense of Satiety

The feeling of satiety doesn't come immediately. For the signal from the intestines to reach the brain via hormones (such as cholecystokinin, peptide YY, etc.), it takes 20 to 40 minutes. It is during this time, when a person is already full, but the brain hasn't received the stop signal yet, that dessert is usually served.

Don't forget psychological factors. Desserts from childhood are associated with celebrations and rewards. Research shows that in company or during holidays, people usually eat more, succumbing to social influence.

Therefore, if after a delicious dinner, you feel the desire to eat a piece of cake - it is a completely normal reaction of the body that seeks new taste sensations and dopamine satisfaction.

This information helps to better understand why even after a hearty lunch, our desire to enjoy dessert does not fade. All this is related not only to physiology, but also to emotional states, memories of pleasant moments, and social traditions. So the next time you crave sweets, remember that this is a natural process.
