Repeated use of fried dough sticks oil will lead to oil aging, dark color, high viscosity and increased smell. Fatty acids, vitamins and other nutrients contained in oils and fats are all destroyed by oxidation, and unsaturated fatty acids polymerize to form macromolecules such as dimers and polymers, which are not easily digested and absorbed by human body.
High risk of illness
Old people eat less, their gastrointestinal function is weakened, and they are prone to vitamin B 1 and B2 deficiency, and fried dough sticks are the most destructive to these two vitamins. Coupled with the harmful substances produced by high-temperature oil, elderly people who eat too much fried dough sticks are prone to coronary heart disease, arteriosclerosis and other diseases, affecting their health.
May cause cancer
Fried dough sticks are high-temperature fried foods. When fried dough sticks are cooked, the oil temperature is as high as 190℃, which may cause cancer. Various polymers, especially dimers, produced by repeated high-temperature heating of unsaturated fatty acids in oils and fats are very toxic, which may affect human growth and development, reduce reproductive function and make liver function abnormal.
Affect physical recovery
For convalescent patients, eating too much fried dough sticks is difficult to digest, which will affect appetite and sleep. Moreover, most of the nutrients in fried dough sticks are destroyed, and high-temperature frying will produce carcinogens, which will not only make patients unable to get nutritional supplements, but also affect their recovery and health.
Affect growth and development
For developing children, eating too many fried dough sticks will combine fatty acids in high-temperature oil with calcium in the intestine to generate soap calcium, which will be discharged from the intestine, thus affecting children's absorption of calcium and affecting their normal development.
People who shouldn't eat fried dough sticks
the aged
The elderly should not eat greasy and indigestible food, because the physiological effect is decreased, the gastrointestinal effect is decreased, and the intestinal absorption is poor. In addition, fried food will destroy the original nutrients, and it is easy to produce toxic substances after high-temperature frying, which will increase the incidence of senile diseases such as coronary heart disease and arteriosclerosis and affect the health of the elderly.
A recovering patient
Patients in convalescence need to repair and restore damaged tissues and organs to increase their resistance. Fried dough sticks are high-temperature fried food with high melting point, which is not easy to digest and affects sleep. Most nutrients in fried dough sticks are destroyed, and high-temperature oil also contains certain toxic substances, which will affect the recovery and health of the body.
pregnant woman
Pregnant women belong to a special group, and their diet needs special attention. Fried dough sticks are indigestible foods and do not meet the dietary requirements of pregnant women. The essential fatty acids and fat-soluble vitamins A, D and E contained in oil after high temperature are destroyed by oxidation, which reduces the nutritional value of oil. Edible oil strips are difficult to supplement various nutrients and can also cause anorexia.
children
So are children. Fatty acids in high-temperature oil combine with calcium in the intestine to form soap calcium, which is excluded from the intestine, affecting children's absorption of calcium, easily causing children's partial eclipse and affecting their normal development. In addition, even healthy adults, eating fried dough sticks is not good for their health. Everyone should try to eat less or not.
