1, can you get stones if you drink milk at night?
In fact, whether the calcium in the diet will form kidney calculi depends on one's own health. If you are a kidney calculi patient, you need to control your calcium intake, especially those with high blood calcium index. There is also a look at what causes stones. If stones are caused by oxalic acid crystallization, we should focus on controlling the intake of oxalic acid and phytic acid in vegetables and pasta.
However, if you are a healthy person, the food rich in calcium in dinner will not affect your health. Especially menopausal women and the elderly, because calcium loss is more, osteoporosis is more common, so in the case of normal heart function, it is necessary to increase calcium intake at night. Milk and bean products in food are the best choices.
In fact, it is better to supplement calcium with milk or yogurt at night. First of all, oxalic acid, phytic acid, calcium-phosphorus ratio, calcium-magnesium ratio and dietary fiber are the biggest factors affecting calcium absorption. Drinking milk during meals or between meals will have these interference factors more or less. But if you drink milk before going to bed at night, these influencing factors will not exist, and the absorption rate of calcium is relatively high; Secondly, early morning is the fastest time for human calcium metabolism. At this time, blood calcium is at a low level, and there is no food intake in this time range, so some elderly people or developing children will have leg cramps at night because of calcium deficiency. However, if you drink a glass of milk or yogurt before going to bed at night, it will provide a good balance for blood calcium levels throughout the day. Moreover, the human body is basically at rest at night, which greatly increases the absorption rate of calcium.
2, the taboo of drinking milk
First, avoid cooking for a long time. As long as milk is cooked for a long time, many nutrients will be lost. For example, if the heating time is long, the colloidal protein particles in milk will dehydrate, change from the original sol state to the gel state, and precipitate out. In addition, unstable phosphate changed from the initial acidic calcium phosphate to insoluble neutral calcium phosphate precipitation. If the heating time is long, the lactose in milk will coke, which will not only turn the milk brown, but also gradually decompose to form lactic acid, and at the same time, it will produce a small amount of potassium acid, which will make the milk sour. If the heating time is long, a small amount of vitamin C contained in milk will also be destroyed.
Second, avoid drinking milk on an empty stomach. Many people are used to drinking a glass of milk for breakfast and not eating anything else, thinking that this will save time and effort and ensure nutrition, but this is very unscientific. Because milk, as a beverage, contains more water, after entering the gastrointestinal tract, on the one hand, it dilutes the gastric juice, so that the gastric juice can not be fully decomposed and enzymatically hydrolyzed, which is not conducive to nutrient absorption; On the other hand, the retention time of milk in the intestine is very short, which is not conducive to the full absorption of various nutrients. Therefore, in order to make the nutrients in milk fully absorbed by the human body, it is best to eat some pasta or other dry food before drinking milk.
Third, avoid adding sugar when milk is heated. Otherwise, lysine in milk and fructose, the decomposition product of white sugar, generate fructosyl amino acids at high temperature. It is not only difficult to be absorbed by human body, but also harmful to human health. The correct way is to heat the milk and dry it a little before adding sugar.
Fourth, it is not advisable to add rice soup to milk to feed the baby, because milk contains many nutrients, especially vitamin A, which is lacking in general food and is high in milk. Starch foods such as noodle rice soup and rice porridge contain a lipoxygenase, which will destroy vitamin A. According to experiments, milk mixed with rice soup will be placed at various temperatures such as cold ice, normal temperature and heating, resulting in amazing loss of vitamin A. Therefore, it is scientifically proved that milk containing vitamin A should not be mixed with starch. Infants' intake of vitamin A mainly depends on dairy products. Long-term lack of vitamin A can lead to stunted growth and weakness in children. Therefore, it is appropriate to feed the baby with milk, milk powder, rice soup and cake dry powder respectively.
Five, avoid cold milk, because cold milk is easy to cause mild diarrhea, but also avoid drinking cold milk taken out of the refrigerator or cellar, especially cold patients.
6. Some people should avoid drinking milk: people with ulcerative colitis, reflux esophagitis, bursitis, pancreatitis and total gastrectomy, and ischemic patients should not drink milk, because milk can stimulate gastric acid secretion more than drinking, and the incidence of peptic ulcer is directly proportional to milk intake. Ischemic patients drink milk when using iron as a blood-enriching drug. Calcium phosphate in milk will precipitate iron and hinder its absorption.
Seven, people who are allergic to milk should also avoid drinking milk. Some people are allergic to milk and have gastrointestinal symptoms such as abdominal pain and diarrhea after drinking. There are also symptoms such as rhinitis and asthma, or respect measles. You should avoid drinking milk.
Eight, workers engaged in lead operations avoid drinking milk, because milk can promote the absorption and accumulation of lead in the human body, which easily leads to lead poisoning.
Nine, boiled milk should not be stored in a thermos. Because milk is a high protein liquid, it is easy to deteriorate at a temperature above 40℃. Thermos bottles will inevitably be contaminated by bacteria, and milk will become a bacteria culture place in thermos bottles, which is easy to get sick after eating.
Ten, plastic bottled milk avoid sunshine, translucent plastic bottled milk, after sunlight, 75% of the milk will produce unpleasant taste, vitamin C will be a lot of loss, vitamin B2 will also be reduced, so avoid using plastic bottled milk, avoid irradiation under fluorescent light.
