1. Increase renal load and hypertension.
If people eat instant noodles for a long time, because of its high salt content, it will increase the kidney load and raise blood pressure.
2. Only calories, no nutrition.
Generally speaking, instant noodles and other convenience foods are foods with high salt, high fat, low vitamins and low minerals, and they do not have the comprehensive nutrition of protein, fat, minerals, vitamins and water that the human body needs.
As far as its main components are concerned, it is mainly carbohydrates, a small amount of monosodium glutamate, salt and seasoning. Its condiments, such as beef juice, chicken juice and shrimp juice, are low in beef, chicken and shrimp meat and lack of vegetables. Some have vegetable powder or vegetable juice, but the amount is very small. So instant noodles can only provide heat, not nutrition.
According to the investigation of nutritionists, among the people who eat instant food for a long time, 60% are malnourished, 54% are iron-deficiency anemia, 23% are vitamin B2 (riboflavin) deficient, 16% are zinc deficient, and 20% suffer from eye diseases due to vitamin A deficiency.
