What are the tonic foods for winter

When the temperature drops in winter, many people are prone to various problems, especially colds are very common. Colds are a very troublesome situation for many of us. Although it is not a serious disease, long-term colds can also have a great impact on our normal life order. Eating more nutritious foods can effectively improve our physical fitness. Let us learn about what tonic foods are in winter.

1. Brain Nutrition

Some foods not only help develop intelligence, make thinking more agile, more focused, enhance memory, comprehensively improve learning ability, and stimulate creativity and imagination, but also help people cope with stress, overcome depression caused by slow thinking, and eliminate pain.

1. Acetylcholine and lecithin

Recent studies in the United States, Britain, Canada and other countries have pointed out that brain function and memory strength are closely related to the acetylcholine content in the brain, in addition to active exercise and mastering the laws of memory. Eating foods rich in lecithin about an hour and a half before an exam can give you a better chance of success. Experiments show that lecithin can improve human intelligence by 25%.

Foods rich in cholecalciferol include: barley malt, peanuts, eggs, calf liver, whole wheat flour, rice, trout, pecans, etc.

2. Protein

Adequate protein is essential for brain function. Many chess champions eat a protein-heavy diet before a grueling match. Protein, especially from fish, is an important brain-boosting food. But when it comes to dinner, should you eat fish first or carbohydrates first? Two competing amino acids in protein - tryptophan and typtophan - compete to enter the brain and play a role. It first enters the gray matter cells of the brain and has an overall effect.

If you want to stay focused and alert after a meal, you should eat protein foods first and then carbohydrates, that is, eat fish first, then potatoes and staple foods; if you want to relax or take a nap after a meal, eat the staple food first. What you eat first is key to the immediate impact of your diet on your brainpower. If a person who does mental work needs to keep his mind sharp all day, he should start with a high-protein breakfast, lunch should be high-protein and low-carbohydrate, and carbohydrate food should be eaten last.

Seafood, beans, poultry and meat contain a large amount of tyrosine, which is the main brain stimulating substance. Cereals, bread, dairy products, potatoes, noodles, bananas, sunflower seeds and other foods are rich in tryptophan. Although they are also foods needed by the human brain, they often have a direct inhibitory effect on brain power for a certain period of time and can easily cause drowsiness after eating.

We must eat more foods that are good for ourselves in winter. Eating them according to the standards of winter tonic foods introduced above will be of great help to us and can effectively reduce the number of times we catch a cold. On the one hand, it can help us reduce the threat of disease, and on the other hand, it can save a lot of unnecessary expenses.
