It depends on what you mean by "ruin your stomach".
If you do not eat regularly or correctly, then your risk of developing gastritis and / or ulcers increases significantly.
Some of the commentators said that nutrition is not important, only the presence of Helicobacter pylori is important. This is absolutely not the case!
This bacterium really plays an important role in the development of, for example, the same ulcer, but its presence in the body is not the primary cause! Helicobacter pylori lives quietly in the body of most people and they, at the same time, do not suffer from gastritis or ulcers.
The fact is that in order to start a pathological chain associated with Hb. pylori, you need to have some kind of defect on the gastric mucosa! And this defect can appear precisely because of improper and / or not quite regular nutrition, stress, etc.
In addition, there are ulcers that form in general in the absence of Helicobacter pylori in the body!

If you are interested in this topic, you can look at the picture. This is "Libra Neck". This is an easy-to-understand display of negative factors that contribute to the "spoilage of the stomach" and counteract them - positive ones (they protect the gastric mucosa).
If the cup of positives outweighs, the person is healthy. If there are few positive factors and they can no longer cope with the negative bombardment that your body is exposed to, "the stomach will deteriorate."

This is a rather old and firmly entrenched opinion in the minds of ordinary people. It is very difficult to get out of the habit of what you have been taught all your life. But here is what the Russian Gastroenterological Association, that is, experts, tells us about this:

"Alimentary errors play, in the opinion of most gastroenterologists, a modest role in the development of functional dyspepsia." (she the same chronic gastritis, but without a pathologist's diagnosis)

As we can see, evidence-based medicine could not find a reliable connection between malnutrition and a ruined stomach.

And between what could it? (order is preserved)

- heredity (children of sick parents suffer from gastritis more often than children of not sick parents);
- smoking (increases the risk by 2 times);
- psycho-social factors (in almost all patients, the development of the disease is preceded by at least one of the vital chronic stress factors);
- H. pylori infection (but even here everything is not so unambiguous).

And one more quote from the same experts:
"The factors contributing to the development of functional dyspepsia are still insufficiently understood."

In our gastrointestinal tract, there is a constant struggle of "beneficial" and "harmful" bacteria.
Food can strengthen one side and weaken the other.

Answer 4

Statistics say that a fairly large number of people are carriers of Helicobacter. But for the occurrence of gastritis, like any other disease in general, a complex of reasons is needed. This includes dietary inaccuracies. What is meant by poor nutrition? Rare meals, "dry food", alcohol, etc. All this within reasonable limits, as a rule, does not harm a initially healthy person. But in excess, one way or another, it leads to damage to the "protective barrier" of the gastric mucosa, "helping" Helicobacter more and more damage to the mucous membrane.
