Will milk lose a lot of nutrients after heating? Can I drink milk if I have a bad stomach?

A netizen asked: I drink a cup of hot milk every morning, but I have always heard people say that a lot of nutrients will be lost after the milk is heated. Is this true?

By the way, I am also a stomach disease patient and have had ulcers before. Will drinking milk all year round affect my health?

Let’s first talk about whether milk can be heated.

In fact, some nutrients (mainly vitamins) will definitely be lost during the heating process of milk.

But how much nutrition is lost depends on the length of heating time.

If heated for 10 minutes, 90% of the vitamin B1 and B6 in the milk can be retained, while 80% of the vitamin B12 remains.

However, if it is cooked for too long, not only will the vitamins be lost significantly and the calcium in the milk will briefly precipitate, but the protein, calcium, fat, etc. will also form a layer of white "milk scale" on the pot, causing additional nutritional loss.

So, if you want to drink hot milk, remember not to boil it for too long.

Tips for heating milk: Stir while heating, and turn off the heat when you see small bubbles rising.

With such “light boiling”, there is no need to worry too much about nutritional loss. Even if there is a slight loss of B vitamins, we can supplement them through other foods.

Finally, let’s talk about whether patients with gastric ulcers can drink milk.

Drinking milk actually has both advantages and disadvantages for patients with gastric ulcers.

On the one hand, milk can dilute and neutralize stomach acid and form a protective film on the surface of peptic ulcers; but on the other hand, the protein decomposition products and calcium in milk will cause increased gastric acid secretion, which is not conducive to the healing of ulcers.

In addition, ulcer patients are likely to be taking alkaline drugs to neutralize stomach acid, such as baking soda, stomach soothing, etc. These drugs may cause adverse reactions when taken with milk.

Therefore, patients with stomach problems should not drink milk before their ulcers heal, but they can still drink it in moderation after healing.
