For example, we have all had the experience of eating too much at a restaurant, getting tired of eating, taking a break at the restaurant, or leaving the restaurant with a heavy stomach. On the contrary, if you eat a meal with little or no oil and less than an eighth of an ounce, you will not feel lethargic, your hunger will be moderately satisfied, and you will be able to move comfortably after the meal. If you compare the post-meal physical condition of a stomach-churning meal and a non-stomach-churning meal, you will intuitively know which is healthier.

On the other hand, if you don't eat at all, what will happen to your body? This brings us to a point worth noting. Hay fever is the bane of many people's existence, but if you skip a meal for a day, you can suppress the hay fever the next day. But when you start eating again, symptoms such as nasal congestion and itchy eyes appear. If you fast for a week, the hay fever will go away, the pimples will disappear, and three hours of sleep will be enough. And when you start eating again, your skin will be smooth and healthy for a period of time.

These results show that food has a great impact on the body, and the relationship between foodstuffs and illness can be seen.
