Nutrition is an indispensable element for the normal operation of the body, if the human body is compared to a machine, the intake of food is the key to ensuring the normal operation of the body.
If the quality and quantity of food needed by the body cannot be guaranteed, the health of the body is bound to be threatened, and then the mood and energy will be affected.
Some experts point out that there are various intricate associations between nutritional imbalances, nutritional deficiencies and various diseases. The body's resistance, immunity enhancement, and physical fitness all depend on scientific and healthy diet and reasonable nutritional supplementation.
1. It is directly related to the function of the brain
If adults are undernourished, fatigue, memory degradation, inattention and other phenomena will occur frequently, and physical strength and mental work will be limited. In addition, if the baby is malnourished, the normal development process of intelligence and physique will be blocked, which can be described as an irreversible effect, and the possibility of inheriting the defect to future generations is still very high.
2. It is related to the occurrence and deterioration of the disease
For example, chronic iron deficiency leads to anemia, iodine deficiency increases the chance of goiter, and vitamin D and calcium deficiencies are more susceptible to rickets.
In addition, malnutrition leads to the weakening of the body's resistance and immunity, and the probability of suffering from infectious diseases will continue to rise; nutritional imbalances are closely related to the occurrence of obesity, cardiovascular and cerebrovascular diseases, and even more, life and health are difficult to be guaranteed.
3. Affect endocrine function
If women are malnourished, there will be amenorrhea, irregular menstruation and other phenomena; if pregnant women cannot keep up with nutrition, the probability of premature birth, fetal congenital malformations and stillbirth will soar; if boys are malnourished, the direct impact is the degradation of sexual function, and the sperm survival rate will be low.
Nutritional diseases refer to a series of diseases caused by imbalances and imbalances in the supply and demand of nutrition. Nutritional deficiency diseases, nutritional intoxication, nutritional metabolism disorders, etc. are all included.
These conditions have a direct and indirect causal correlation with excessive and undernutrition intake, such as obesity, diabetes, tumors, hypertension, coronary heart disease, etc. have a definite correlation with nutrition.
1. Primary nutritional deficiency
Nutritional deficiencies caused by individual nutrients or inadequate intake of multiple nutrients.
There are three common reasons for insufficient simple nutritional intake: one is the lack of nutritional deficiencies caused by picky eating, partial eating and various fasting, such as the lack of certain essential elements in the body; the second is the shortage of food caused by external factors such as war and poverty; and the third is the unscientific cooking and processing methods that lead to the destruction or loss of nutrients in food. For example, vegetables are cut and then washed, heated, and boiled excessively, resulting in a large loss of vitamin C.
2. Secondary nutritional deficiency
Diseases, medications, physiological changes and other reasons lead to digestion, malabsorption disorders, increased nutritional requirements, and the final result is nutritional deficiencies.
For example: coma, oral and gastrointestinal diseases leading to food intake, swallowing difficulties; digestive tract diseases, gastrointestinal surgery caused by nutrient malabsorption disorders; anticonvulsants, neomycin and other drugs caused by nutrient absorption, utilization disorders, etc.; pregnant women due to pregnancy, breastfeeding and other special factors so that the body's demand for nutrients in a certain period of time far exceeds the usual.
3. Excess nutrition or imbalance
Fat and calorie excesses induce obesity, hyperlipidemia and other diseases; excessive salt intake and low-fiber diet increase the likelihood of high blood pressure; at the same time, excess nutrition will also increase the probability of various malignant tumors.
The causes of nutritional imbalance or imbalance are mainly the following two points
First, it is an unreasonable dietary structure: animal foods in the daily diet account for far more than plant foods, too many refined processed foods, and the intake of fresh vegetables and fruits is small, which is the most important cause of overnutrition and imbalance.
The second is unhealthy eating habits: high salt, high fat, high calorie food intake is too much, if the meal is hearty, often overeating.
Through the above introduction, I believe that everyone has realized the importance of reasonable nutrition in health care and disease prevention.
Nutrition can keep up with it to ensure that the body's tissues have new capital, the body's immunity and resistance to diseases can be further strengthened, the normal development process of infants and young children will be guaranteed to the greatest extent, and the incidence of various cardiovascular diseases, obesity, tumors and other diseases can be controlled within a low range.
