Introduction: As a nutritious food, milk is almost everyone's top choice for breakfast, especially for women who regard it as a great product for whitening and beautifying the skin. However, milk is not suitable for everyone. So, which people should not drink milk? Below, the editor reminds you that drinking milk can be fatal for the following 8 groups of people.
1. People who are frequently exposed to lead
The lactose in milk can promote the absorption and accumulation of lead in the human body, easily leading to lead poisoning. Therefore, people who are frequently exposed to lead should not drink milk and can switch to yogurt, as it contains very little lactose, most of which has been converted into lactic acid.
2. People with lactose intolerance
Some people have a severe deficiency of lactase in their bodies. As a result, the lactose in the milk they consume cannot be converted into galactose and glucose for absorption and utilization by the small intestine. Instead, it goes directly into the large intestine, increasing the osmotic pressure in the intestinal cavity and causing the large intestinal mucosa to absorb a large amount of water. In addition, when lactose is fermented by bacteria in the intestine, it can produce lactic acid, lowering the intestinal pH value to below 6, which irritates the large intestine and causes symptoms such as bloating, abdominal pain, gas, and diarrhea.
3. Patients who have undergone abdominal or stomach surgery
The patient's lactase levels can be affected and reduced. After drinking milk, the undigested lactose ferments in the body, producing water, lactic acid, and a large amount of carbon dioxide, causing the patient to bloat. During abdominal surgery, the intestines are exposed to the air for a long time, and the mesentery is stretched, which delays the recovery of postoperative intestinal motility. Gas produced from swallowing or fermentation in the intestinal cavity cannot be expelled in time, worsening the bloating, which can lead to abdominal pain, increased intra-abdominal pressure, and even rupture of the suture or the abdominal incision. After gastric surgery, the remaining gastric pouch is very small, and milk containing lactose will quickly rush into the small intestine, making the already insufficient or deficient lactase even more insufficient or deficient.
4. Patients with Irritable Bowel Syndrome (IBS)
This is a common functional bowel disease characterized by abnormal physiological responses of intestinal muscle movement and intestinal mucous membrane secretion to stimuli, without any structural damage to the intestine. Symptoms are mainly related to psychological factors and food allergies, including allergies to milk and its products.
5. Patients with cholecystitis and pancreatitis
Digesting the fat in milk requires a supply of bile and pancreatic enzymes. Milk increases the burden on the gallbladder and pancreas, which exacerbates the symptoms.
6. People who usually experience bloating, excessive gas, abdominal pain, and diarrhea
Although these symptoms are not caused by milk, drinking milk can worsen them.
7. People allergic to milk
Some people experience symptoms such as abdominal pain and diarrhea after drinking milk. In severe cases, they may even develop rhinitis, asthma, or urticaria.
8. Patients with reflux esophagitis
Milk has the effect of reducing the pressure of the lower esophageal sphincter, which increases the reflux of gastric or intestinal fluids and worsens esophagitis.
