1. Broccoli

Broccoli is particularly rich in soluble dietary fiber. This fiber can only be broken down in the large intestine and produce a lot of gas. Broccoli also contains gas-producing sugars similar to those found in beans.

2. Tomatoes

Tomatoes are highly acidic and may stimulate the stomach to produce more gastric acid. Therefore, eating too many tomatoes can lead to symptoms such as pantothenic acid and heartburn. The same goes for ketchup made from tomatoes.

3. Dairy products

People with lactose intolerance may suffer from gastric discomfort after consuming dairy products. Choose yogurt, hard cheese, or low-lactose milk.

4. Greasy foods

Foods that are too high in fat, such as fried foods, will increase the chance of pantothenic acid and irritable bowel syndrome. Because high-fat foods are difficult to digest, the body automatically secretes more gastric acid. Likewise, overeating can stimulate excessive gastric acid secretion.
