Studies show that lack of sleep can lead to obesity August 03, 2017 Source: Xinhua News Agency A recent study by British researchers based on the UK population found that lack of sleep is more likely to cause weight gain or even obesity, and that people's metabolic health levels are also low. Researchers at institutions such as the University of Leeds in the United States reported in the US Science Public Library·Comprehensive that they collected data on sleep duration, diet records, blood samples and body weight of 1,615 British adults, and the relationship between sleep and health. Expand the analysis. The analysis found that people who stayed on average for about 6 hours per night had a waist circumference that was 3 cm more than those who slept 9 hours a night. In general, people with shorter sleep periods in this group had higher body weight. The researchers believe that this result further proves that lack of sleep may increase a person's risk of developing metabolic diseases such as diabetes. One of the authors of the report, Leeds University scholar Greg Porter, said that the number of people with obesity problems in the world has more than doubled since 1980. Obesity causes many diseases, the most widely known is type 2 diabetes, so understand why people Increased weight is very important for public health management. In addition, the analysis also found that the shorter sleep time is related to the lowering of the body's high-density lipoprotein cholesterol (good cholesterol) level, which may cause many health problems. Higher HDL cholesterol levels can reduce the risk of a person suffering from diseases such as heart disease. However, the researchers also said that this is only a result based on a large number of data observations, and it is not possible to draw a final conclusion on this. Different people need different amounts of sleep every day, but a relatively recognized view in the academic world is that for most adults. 7 to 9 hours of sleep time is the best choice.

Vitamins:
Vitamin A:
Retinol. Carotene compounds responsible for transmitting light sensation in the
retina of the eye. Deficiency leads to night blindness.
Beta carotene: An
antioxidant which protects cells against oxidation damage that can lead to cancer.
Beta carotene is converted, as needed, to vitamin A. Food sources of beta
carotene include vegetables such as carrots, sweet potatoes, spinach and other
leafy green vegetables; and fruit such as cantaloupes and apricots. Excessive
carotene in the diet can temporarily yellow the skin, a condition called
carotenemia, commonly seen in infants fed largely mushed carrots.
Vitamin B1:
Thiamin, acts as a coenzyme in body metabolism. Deficiency leads to beriberi, a
disease of the heart and nervous system.
Vitamin B2:
Riboflavin, essential for the reactions of coenzymes. Deficiency causes
inflammation of the lining of the mouth and skin.
Vitamin B3:
Niacin, an essential part of coenzymes of body metabolism. Deficiency causes
inflammation of the skin, vagina, rectum and mouth, as well as mental slowing.
Vitamin B6:
Pyridoxine, a cofactor for enzymes. Deficiency leads to inflammation of the
skin and mouth, nausea, vomiting, dizziness , weakness and anemia.
Folate (folic
acid): Folic acid is an important factor in nucleic acid synthesis (the genetic
material). Folate deficiency leads to megaloblastic anemia.
Vitamin B12: An
essential factor in nucleic acid synthesis (the genetic material of all cells).
Deficiency leads to megaloblastic anemia, as can be seen in pernicious anemia.
Vitamin C:
Ascorbic acid, important in the synthesis of collagen, the framework protein
for tissues of the body. Deficiency leads to scurvy, characterized by fragile
capillaries, poor wound healing, and bone deformity in children.
Vitamin D: A
steroid vitamin which promotes absorption and metabolism of calcium and
phosphorus. Under normal conditions of sunlight exposure, no dietary
supplementation is necessary because sunlight promotes adequate vitamin D
synthesis in the skin. Deficiency can lead to osteomalacia in adults and bone
deformity (rickets) in children.
Vitamin E:
Deficiency can lead to anemia.
Vitamin K: An
essential factor in the formation of blood clotting factors. Deficiency can
lead to abnormal bleeding.
Nutritions:
For the treatment
of nutritional disease, any of the nutrient-related diseases and conditions
that cause illness in humans. They may include deficiencies or excesses in the
diet, obesity and eating disorders, and chronic diseases such as cardiovascular
disease, hypertension, cancer, and diabetes mellitus. Nutritional diseases also
include developmental abnormalities that can be prevented by diet, hereditary
metabolic disorders that respond to dietary treatment, the interaction of foods
and nutrients with drugs, food allergies and intolerances, and potential
hazards in the food supply. All of these categories are described in this
article. For a discussion of essential nutrients, dietary recommendations, and
human nutritional needs and concerns throughout the life cycle, see nutrition,
