Apply the '4 less - 4 more' rule for a longer life.

There's an old saying, "Misfortune comes from the mouth - Illness enters through the mouth," meaning that eating and drinking have a significant impact on one's health.

Whether people can live long, healthy lives depends not only on what they eat but also, importantly, on how they eat.

So remember these four "less" and four "more" eating rules to keep your body healthy:

Fruits and vegetables are very good foods for the body.

1. Eat less meat and more vegetables.

Animal meat contains a lot of fat, protein, cholesterol, etc., which, when entering the body, are metabolized into acids that harm cells.

Meanwhile, fruits and vegetables contain more nutrients that are good for the body, such as vitamins and minerals, which help to alkalize the body and prevent aging.

2. Eat less sugar and more fruit.

Sugar is on the blacklist of foods that make the body heavy and age faster. When sugar enters the body, if not fully utilized, it accumulates as fat, causing blood sugar imbalances leading to diabetes.

Fruits provide vitamins, minerals, and fiber.

Although fiber has no nutritional function, it supports the digestive process, prevents constipation, and makes it easier for toxins and excess cholesterol to be excreted from the body.

3. Eat less salty food and more sour food.

A diet too high in salt can harm the heart, kidneys, and other organs.

Numerous studies have shown a correlation between high salt consumption and high blood pressure in older adults. When the body absorbs excessive amounts of salt, it increases the pressure of blood against the artery walls.

Therefore, consuming too much salt increases the risk of high blood pressure. People with high blood pressure also have a higher risk of stroke or other cardiovascular problems.

At the same time, when the body contains too much salt, it increases pressure on the kidneys, making you more susceptible to kidney stones.

Eating plenty of acidic foods can help you lose weight faster and support a healthy digestive system. However, caution is needed if you have stomach acid problems.

4. Eat less - chew more

Whether you feel full or not doesn't depend on the quantity of food, but on how you eat. You should eat small portions and divide them into several meals throughout the day. Avoid letting your body get too hungry or too full, as both are harmful to your stomach.

Eating less but chewing slowly and thoroughly will keep you feeling full longer than eating a lot but chewing quickly.

When eating, take your time, eat slowly, chew thoroughly, both to enjoy the flavor of the food and to allow your body to gradually absorb the nutrients.

It is especially important not to eat while doing other tasks so that the brain can focus solely on digesting food, increasing absorption efficiency.
