Some people say: coffee with milk will produce calcium oxalate, will bring kidney stones and other problems, coffee contains oxalic acid, or there are other ingredients, also ask what are the ways to eat coffee with milk, for example: Vietnamese coffee: condensed milk instead of milk and sugar, coffee heated on iron cans and lights, resulting in siphon effect, added to the coffee has a trench flavor.

Coffee itself is rich in calcium oxalate. Too much calcium oxalate will cause kidney stones, but can drink stones should be too much!

And there should be other physical conditions before there is a chance to develop kidney stones.

The health effects of ● coffee include:

1. Contains caffeine, which can raise blood pressure in some sensitive patients.

2. High potassium content should be avoided in patients with renal failure.

3. Caffeine stimulates gastric acid secretion, relaxes the smooth muscle vessels of the digestive system, accelerates food metabolism, and reduces the nutritional value of food-peptic ulcer.

4. Caffeine can reduce the secretion of insulin in the pancreas, reduce the tolerance of glucose, increase the excretion of insulin and increase blood sugar. Patients with diabetes should not drink.

5. Caffeine can stimulate the brain power center, and xanthine can constrict blood vessels and reduce blood flow to the brain. It is very disadvantageous to patients with epilepsy.

6. Coffee will increase the content of fat and triglycerides, increase the burden of the heart and the consumption of oxygen. Especially when the body is tired and excessive smoking is more likely to cause.

7. Coffee will accelerate the metabolism of food and reduce the absorption rate of iron. People with iron deficiency anemia should avoid drinking.

8. Coffee is a food rich in oxalic acid. Patients with kidney stones should fast to prevent recurrence of calcium oxalate stones.

9. Long-term drinking coffee will affect the sedative effect, increase the number of wakefulness, make the sleep depth shallow, and cause insomnia.

● on the extension of coffee with milk to prevent calcium loss:

1. Milk for the human body, the protein is too high, the human body does not need so much protein, and when there is too much protein, the human body will naturally metabolize, and when the human body metabolizes too much protein, the body will release a large number of acidic substances, the process will also release alkaline substances to combine with them, and the most alkaline substance in the human body is calcium. So when a large amount of acid is produced, the body automatically takes calcium out of your bones and even teeth to neutralize the acid.

two。 It is generally said that the production of calcium in the body decreases with age, so it is necessary to drink more milk to prevent osteoporosis, but it may be just the opposite, because the concentration of calcium in the blood immediately increases after drinking milk, which helps to absorb. However, when the calcium in the blood reaches a certain level, the body will excrete rapidly through the kidneys in order to maintain the constant state of calcium in the body. However, when the human body is excreting, he is unable to tell what the excess calcium is, so he often takes other useful calcium with him, not only that, but also along with other minerals such as magnesium, zinc and iron. Even amino acids and vitamins are excreted with the urine. The so-called "milk calcium is easy to absorb" actually seems to have the opposite effect, along with the excess calcium, even the necessary calcium or other nutrients will be excreted.

● above I think that drinking coffee and milk to reduce calcium loss is a palliative rather than a permanent cure. Basically, unless there is a bogey effect of physical discomfort, drink the right amount if you really like it. I also love drinking coffee. The first thing I do when I get up every day is to make coffee, but adding milk or condensed milk or chocolate or brandy is fun to add flavor!
