1, chocolate
German nutritionists say that eating chocolate will make people feel happy, because chocolate will release serotonin in the brain. Compound amine is formed by tryptophan, which can't be produced by human body itself, and it can only rely on food ingested from the outside. Chocolate itself has a low tryptophan content, but it contains a lot of sugar, which can trigger the production of insulin.
Insulin ensures that sugar enters cells, and the remaining tryptophan enters the brain to synthesize serotonin. When serotonin stays in the neural bonds of the brain, it will have a positive impact on people's mood. Besides chocolate, sweets such as bananas and puddings can also achieve this effect and help people get rid of depression.
Step 2: bananas
Bananas contain a substance called alkaloids, which can boost people's spirit and confidence. Bananas are the source of tryptamine and vitamin B6, which can help the brain to make serotonin.
3. Spinach
Spinach not only contains a lot of iron, but also contains folic acid needed by human body. Medical literature has always pointed out that folic acid deficiency can lead to mental diseases, including depression and early-onset diseases. The study also found that those who can't get enough folic acid can't sleep after five months, and have symptoms such as forgetfulness and anxiety.
4, deep-sea fish
The study found that people living by the sea all over the world are happier. This is not only because the sea is refreshing, but also because people who live by the sea eat fish more often. According to the research of Harvard University, Omega-3 fatty acids in marine fish have similar effects with commonly used antidepressants such as lithium carbonate, which can block the nerve conduction pathway and increase the secretion of serotonin.
5.cherry
Cherry is called natural aspirin by western medicine. Because there is a substance called anthocyanin in cherry, which can create happiness. Scientists at the University of Michigan believe that eating 20 cherries when people are in a bad mood is more effective than taking any medicine.
6. Low-fat milk: A study at Mount Sinai Medical Center in new york found that after taking 65,438+0,000 mg of calcium tablets for three months, three-quarters of premenstrual syndrome women felt happier and less nervous, irritable or anxious. In daily life, the best sources of calcium are milk, yogurt and cheese. Fortunately, low-fat or skim milk contains the most calcium.
7. Grapefruit: The high content of vitamin C in grapefruit can not only maintain the concentration of red blood cells, but also make the body resistant, and vitamin C can also resist pressure. Most importantly, vitamin C is one of the important components that produce dopamine and adrenaline.
