The following eight types of foods can help resist depression and have significant effects on treating depression. 1. Deep-water fish: Some studies believe that the Omega-3 fatty acids in fish oil can produce similar effects to commonly used antidepressants such as lithium carbonate, reducing people's psychological anxiety. 2. Banana: Banana contains a substance called alkaloid, which can boost your spirit and improve your confidence. And bananas are the best source of tryptophan and vitamin B6, which can help the brain reduce depression. 3. Grapefruit: Grapefruit not only has a rich fragrance, but can also purify complex thoughts and refresh the mind. The high amount of vitamin C it contains can not only maintain the concentration of red blood cells and increase resistance, but also participates in the body's production of dopamine and adrenal hormones. One of the important components of "exciting" substances. 4. Spinach: In addition to containing a lot of iron, spinach also contains folic acid that the human body needs. A lack of folic acid in the human body can lead to mental illnesses, including depression and Alzheimer's disease. Studies have found that people who do not consume enough folic acid are unable to sleep and develop symptoms such as forgetfulness and anxiety after 5 months. 5. Garlic: A German study on the effect of garlic on lowering cholesterol found that after eating garlic, people felt less tired, less anxious, and less likely to get angry. 6. Pumpkin: Pumpkins can create a good mood because they are rich in vitamin B6 and iron. These two nutrients can help the body's stored blood sugar to be converted into glucose. Glucose is the only fuel for the brain and can help the body maintain strong energy. . 7. Low-fat milk: A study in the United States found that after women with premenstrual syndrome took 1,000 mg of calcium tablets for 3 months, 3/4 of them became less nervous, irritable or anxious. Low-fat or skim milk is the best source of calcium. 8. Foods containing selenium: After British psychologists gave subjects 100 micrograms of selenium, the subjects generally responded that they felt in good spirits and their thoughts were more coordinated. Rich sources of selenium include dried fruits, chicken, seafood, whole grains, etc. Complex carbohydrates, such as whole-wheat bread and soda crackers, contain trace minerals such as selenium, which can improve mood.
