The reason for the lack of vitamin B2
Vitamin B2 is not commonly found in natural foods, but is found in animal liver, kidney, heart and eggs, milk, crabs, squid, green leafy vegetables, seaweed, mushrooms, fresh beans, and peanuts. The human body does not ingest these foods for a long time and it will cause the deficiency of vitamin B2.
Vitamin B2 is easily oxidized and easily decomposed in an alkaline environment. Inappropriate cooking methods can cause significant loss of vitamin B2.
Vitamin B2 is involved in the formation of various coenzymes in the body, as well as a series of complex biochemical reactions. When the body's physiological load increases or stress, the body's need for vitamin B2 increases, resulting in vitamin B2 deficiency.
How many vitamin B2 do the human body need each day?
The daily intake of vitamin B2 recommended by the China Nutrition Society for Chinese residents is 0.4 mg for infants and 0.6 mg for one year, and then gradually increases with age. It will be 1.3 mg per person per day by the age of 12 years. Adults and old people are also between 1.1 and 1.3 milligrams. Only the teenager is in a stage of vigorous growth and growth, and the dosage is increased. For example, a 16-year-old male is 1.8 mg per day and a female is 1.6 mg per day. Pregnant women increased to 1.8 mg per day and lactating mothers increased to 2.1 mg. The amount of vitamin B2 is also correspondingly increased for people with large amounts of exercise and physical strength.
Excessive intake
Itching, numbness, tingling, burning and other symptoms.
Urine color is yellowish.
Excessive intake will be discharged with urine and will not be poisoned.
Precautions:
The excess vitamin B2 does not accumulate in the body and needs to be replenished daily. When ingesting high-calorie foods, intake should be increased.
At the same time taking vitamin B2, B6, C and other effects are best, especially those who are nervous.
Vitamin B2 is easily destroyed by UV rays. Therefore, you should avoid exposing it directly to the sun before eating food. Even milk in plastic bottles or cartons should avoid exposure to light for too long.
When cooking, alkaline baking soda added to make the dish greener will destroy vitamin B2 and should be avoided.
Since high-fiber foods increase the peristalsis of the intestine and speed up the passage of food in the intestine, thus reducing the absorption rate of vitamin B2, it is best not to consume this type of food at the same time when taking vitamin B2.
