It is not difficult to understand that diet has an important impact on human health. However, with the further deepening of research on diet and health in recent years, people are increasingly aware that diet is equally important to people's mental health.

"Junk food" high in sugar and fat not only makes your waistline and weight soar, but also brings a series of problems such as emotional and mental health.

Here's an overview of the link between diet and mental health, and how you can improve your mental health by adjusting your diet.

The importance of diet and blood sugar

First of all, the diet should be regular, so as to ensure the stability of blood sugar.

If you eat irregularly, it may lead to a drop in blood sugar, which will lead to fatigue and irritability. Fluctuating blood sugar levels can lead to mood disturbances and even symptoms including depression and anxiety. If you eat erratically, your blood sugar will go up and down, causing more damage to your body than just your hungry stomach rumbling.

If you are constantly hungry during the day, it can affect your mood, concentration and energy. Therefore, eat regularly during the day to keep blood sugar stable. But that doesn't mean you're eating non-stop, as constant snacking can affect appetite and insulin function.

In addition, not drinking enough water can also affect your mental health. If the body is dehydrated, it can make it difficult to concentrate and think clearly. Like the rest of the body, brain cells need water to function properly. That's why dehydrated people are more prone to nervousness.

Water helps blood flow, and not having enough water to help remove toxins from the body can make a person feel weak. Dehydration can also increase cravings for unhealthy foods and beverages, such as potato chips, alcohol, carbonated and caffeinated beverages.

Drinking alcohol will reduce people's cognitive function, because the human body needs water to remove alcohol from the blood, which will lead to further dehydration in the human body, which in turn affects cognitive function. Although sugary carbonated drinks will quickly replenish the body's energy, the subsequent sudden drop in blood sugar will also make people feel tired and mentally fatigued.

Balanced Diet and Mental Health

So how important is a balanced diet to mental health?

Numerous studies have shown that a healthy diet can prevent depression. Depression has become a major mental health problem worldwide.
Diet is one of the most important factors affecting the health of your gut and its bacteria. The gut, in turn, affects a person's mental health. Eating a balanced diet provides the brain with the nutrients it needs to maintain a positive mood and improves signaling between brain cells to keep it functioning at its best. The nutrients needed to maintain physical and mental health are very rich, so it is important to eat a varied diet and eat more foods that you usually eat little or not at all.

When you're tired, you're more likely to be tempted by foods high in calories, sugar, and fat. If you only do it occasionally, it's not a big deal. But it must not form a habit and dependence.
