How do you know you are malnourished? In this day and age, there are very few malnourished people in our country, almost all of them are overnourished. Unless those who lose weight or have gastrointestinal disorders that are not well absorbed by the diet suffer from malnutrition. Malnutrition must be confirmed by the indicators in the hospital, usually the blood biochemistry test, low albumin, low triglycerides, low creatinine, low iron content, if you have all these indicators are normal, you are not malnourished. As long as we eat normally, we are not malnourished. So if you don't have a disease, it's impossible to be malnourished.
If the albumin, triglyceride, creatinine, iron and other really low values, then usually eat well, three meals a day seriously, every day to eat two eggs or eat some fish or eat some meat products, milk and so on, or fried food, eat some fruits and vegetables, then a week, your albumin and triglyceride own creatinine and so on the indicators will be normal. So, malnutrition is best addressed. Correct the malnutrition and the immunity will slowly normalize. Do as I say.
