Introduction: Even for healthy individuals, excessive milk consumption is not advisable; 200 milliliters a day is sufficient. Drinking too much milk can, on the contrary, easily lead to osteoporosis.
I. Patients with Iron-deficiency Anemia
The iron in food must be converted into ferrous iron in the digestive tract to be absorbed and utilized. If one drinks milk, the ferrous iron in the body combines with the calcium and phosphates in milk to form insoluble compounds, which affects iron absorption and utilization, and is detrimental to the recovery of anemia patients.
II. Patients with Reflux Esophagitis
Research has confirmed that milk containing fat affects the contraction of the lower esophageal sphincter, thereby increasing the reflux of gastric or intestinal juice and aggravating the symptoms of esophagitis.
III. Patients After Abdominal Surgery
Such patients often have intestinal bloating. Milk contains a relatively high amount of fat and casein, which is not easily digested in the stomach and intestines. It can ferment and produce gas, worsening intestinal bloating and hindering the recovery of intestinal peristalsis.
IV. Patients with Peptic Ulcers
Although milk can alleviate the irritation of gastric acid on the ulcer surface, it stimulates the gastrointestinal mucosa to secrete a large amount of gastric acid, which can worsen the condition. Sun Yat-sen's stomach condition worsened after following the advice of a Western doctor who believed that milk, as a liquid, was easily digestible and beneficial for stomach ailments. Later, he stopped drinking milk and switched to a vegetarian diet, and his stomach condition improved.
V. Patients with Lactase Deficiency
Milk has a high lactose content, but it must be broken down into galactose and glucose by the enzyme lactase in the digestive tract to be absorbed by the human body. If lactase is deficient, consuming milk can cause abdominal pain and diarrhea. About three-quarters of Chinese people are lactose intolerant, so one must be cautious and it is best to consume it in small amounts.
VI. Patients with Cholecystitis and Pancreatitis
The digestion of fat in milk requires the participation of bile and pancreatic lipase. Drinking milk will increase the burden on the gallbladder and pancreas, thereby aggravating the condition.
In addition, patients with colds and individuals with a phlegm-dampness constitution should also avoid drinking milk.
Even for healthy individuals, excessive milk consumption is not advisable; 200 milliliters a day is sufficient. Drinking too much milk can, on the contrary, easily lead to osteoporosis. This is a conclusion reached by scientists. People who eat too much meat should also avoid drinking too much milk, because excessive meat consumption makes the body acidic, which can lead to the excretion of calcium. An acidic body is a major cause of cancer. In conclusion, everything should be in moderation. It is better to follow the advice of nutritionist Chen Junshi and the research findings of nutritionist Campbell, and to follow the old wisdom: make plant-based foods the main part of your diet.
