Maintaining the normal function of the eyes and the normal work of the eyes requires the consumption of many trace elements, which, if not replenished in a timely manner, can cause various abnormalities in the eyes.
Take the right amount of vitamin A
A lack of vitamin A in the body not only affects the normal development of the body, but is also a major cause of night blindness and other eye diseases.
The vitamin in food
After digestion and absorption by the body, it can remain in the body for a longer period of time and will not be excreted due to excessive levels. Vitamin A in food is resistant to high temperatures and does not suffer large losses due to high temperatures during cooking. However, the acid resistance of vitamin A is relatively weak and is easily damaged by acidic foods. Therefore, foods rich in vitamin A should not be cooked at the same time as acidic foods to avoid the loss of vitamin A for nothing.
Foods rich in vitamin A include carrots, spinach, peanuts, tomatoes, peppers and other vegetables and fruits, and various seafood.
Take the right amount of vitamin B1
If the body lacks vitamin B1, it will not only cause the function of the stomach, intestines and other digestive system to weaken, resulting in loss of appetite, fatigue and weakness of the limbs, but also cause the resistance of the optic nerve system of the eyes to weaken significantly, resulting in symptoms such as optic neuritis, which affects vision.
Unlike vitamin A, which can accumulate in the body, vitamin B1 is excreted every day with metabolism, so to ensure that there is a sufficient amount of vitamin B1 in the body, you must eat a certain amount of food containing vitamin B1 every day. Vitamin B1 is easily dissolved in water, so when washing vegetables rich in vitamin B1 such as spinach, it is best not to chop it first, and the water should be controlled when cooking, so as not to lose too much vitamin B1 and reduce the body’s intake accordingly, thus causing the lack of vitamin B1 in the body.
Foods rich in vitamin B1 include various green leafy vegetables, soybean products, lean meat and various seafood.
Take the right amount of vitamin B2
A lack of vitamin B2 in the body can also cause a weakened digestive system and affect the normal development of the human body, and can also easily induce various inflammatory diseases, such as stomatitis, stomatitis and inflammation of various eye tissues. Many people have unexplained dry eyes, inflammation of eyelids and conjunctivitis at the time of seasonal change, which is the result of temporary metabolic disorder when the body adapts to the seasonal change, making the body lack vitamin B2.
Vitamin B2 has strong acid resistance and is not afraid to cook with acidic foods, but has weak alkaline resistance and is easily destroyed by alkaline foods, so foods containing vitamin B2 should not be cooked with alkaline foods. Vitamin B2 is also easily soluble in water, so it is also important to control the water when cooking so as not to lose too much vitamin B2. When storing vitamin B2 pills, seal them in brown glass bottles or opaque glass bottles and do not expose them to direct light or keep them in a humid place.
Foods rich in vitamin B2 include milk, milk products, cheese, lean meats, egg yolks, various green vegetables and various seafood.
Take in the right amount of calcium
Calcium plays a very important role in the development of the human body, especially for the development and growth of bones, teeth and eye structures. A lack of calcium in the human body not only predisposes to diseases such as chondromalacia and abnormal dental development, but also causes structural abnormalities in the eye, which can lead to abnormal development of intraocular tissues and other eye diseases. Calcium in food is easily affected by acidic objects and becomes acidic calcium, which is not absorbed by the body. Therefore, when eating calcium foods, do not eat acidic foods at the same time, and be careful not to mix the two together in cooking. Foods rich in calcium include various dairy products, various soy products, foods with more protein and various fish products.
Eat less sweets
Sweets are foods that contain high levels of sugar. Sugar is not harmful to normal people, but when sugar is digested and absorbed in the body, it requires a lot of vitamin B1. If the body consumes too much sugar, it is easy to cause vitamin B1 deficiency, which can lead to abnormalities in the optic nerve system of the eyes. Excessive sugar also consumes a lot of calcium, which in turn can cause abnormalities in the structure of the eye, resulting in reduced scleral elasticity and eye deformation. Therefore, it is best to eat less sugar and foods with high sugar content, especially children and adolescents in the growth and development period, and not to crave sweet food.
Balance the pH level in the body
The pH of a normal human body is basically balanced, sometimes slightly weak alkaline. If too much acidic food is consumed, the alkalinity of the body will decrease and the acidity will increase. The relative increase in acidity will cause slight changes in the cornea, ciliary muscle and sclera of the eye, which will easily enhance the chance of myopia. Young children and adolescents like to eat sweet and sour foods, but sweet and sour foods are weakly acidic foods, long-term eating more may make young children and adolescents are weakly acidic body, which will have certain adverse effects on the normal development and growth of children. Therefore, the choice of food should pay attention to the balance of acidity and alkalinity, do not like to eat more, do not like to eat less or do not eat, but to acidic and alkaline foods are eaten.
Alkaline food is mostly a variety of beans and soy products, green vegetables, radish, sesame and seaweed and other sea food.
Acidic foods are mostly sugary foods and fish, meat, dairy foods and fruits, etc.
