Damage of diabetic eye disease to fundus: Long-term excessive consumption of sugar or dessert will lead to high blood sugar and poor metabolism, thus inducing diabetes. Diabetes manifests itself in the eyes-"diabetic eye disease" can induce a series of malignant eye diseases, including glaucoma, cataract, optic atrophy, macular degeneration, retinal detachment, fundus hemangioma, fundus hemorrhage, dacryocystitis, vitreous opacity and so on, among which the first five eye diseases have higher blindness rate. Therefore, "diabetic eye disease" has a great destructive effect on eye health.
(Diabetic macular degeneration)
(Diabetic fundus hemorrhage)
Inducing cataract: it will accelerate the metabolism of lens and the deposition of metabolites, thus accelerating the formation of cataract that forms lens.
Inducing open-angle high intraocular pressure glaucoma: Long-term excessive consumption of sugar or dessert will change aqueous humor concentration, increase lens density and intraocular pressure, which will easily induce open-angle high intraocular pressure glaucoma and eventually lead to blindness.
Second, eating too much sugar will be harmful to the overall physical and mental health:
Turn into fat. After eating too much sugar, too much sugar will be converted into fat in the body, leading to obesity and becoming a potential cause of cardiovascular disease. The ingested polysaccharide is converted into fat in the body, leading to obesity, hypertension (cardiovascular disease) and hypertension (heavy heart load, lack of oxygen in hands, feet and brain).
Induce diabetes. Diabetes mellitus, as a systemic chronic disease which is extremely difficult to cure, has a very serious destructive effect on the skin, eyes, nervous system and important internal organs. We must be on high alert for diabetes.
Affect appetite and lead to nutritional deficiency. Sugar can only provide calories and has no other nutritional value. If you eat too much sugar every day, you will inevitably eat less other nutrients, which will lead to the lack of protein, vitamins and minerals in your body and easily lead to malnutrition. If the child suffers from dental caries, it will hurt when chewing, and his appetite will also be affected. After a long time, their food intake will decrease and there will be nutritional deficiency.
Gastric hyperacidity causes gastritis. Eating sweets can cause hyperacidity, stimulate the stomach and cause gastritis.
Causing tooth decay. After eating more sugar, it will provide favorable conditions for lactic acid bacteria in the mouth. Sugar stays in the mouth and is easily decomposed by lactic acid bacteria to produce acid, which decalcifies teeth and induces the formation of dental caries. Most of the enamel coated on the tooth surface forms hydroxyapatite (a kind of calcium phosphate) crystals, which will dissolve violently in acidic environment below PH5. Usually, the PH value in the oral cavity is kept at around 6-7. When the ingested sucrose is rapidly hydrolyzed by salivary enzymes, acidic substances can reduce the PH value to about 4, which is the cause of tooth decay.
Lead to calcium deficiency and easy fracture.
Susceptible to skin diseases such as sores and furuncles.
It leads to metabolic disorder and weakens the immune system's ability to prevent diseases.
Eating too many sweets will produce physiological dependence similar to taking chemicals. ?
Conclusion: How to eat sugar scientifically-control the intake (0.5/ day /kg body weight, 60kg body weight, 30g/ day).
