1. Onions

Onions contain a variety of nutrients, which can protect the heart and soften blood vessels. However, onions can cause gastrointestinal discomfort, causing symptoms such as bloating or cramping.

2. Broccoli

Broccoli contains a large amount of vitamins and dietary fiber, which has anti-cancer and anti-aging effects. However, high-fiber vegetables can expand the stomach capacity and can easily cause gastrointestinal bloating. Especially people with gastric ulcers should not eat more high-fiber foods.

3. Potato puree

The creamy potato puree is easy to eat. No wonder it ranks at the forefront of "the most comfortable food". But if you are allergic to sugar, you will not feel comfortable because it contains milk and a lot of cream. Making sugar-free potato puree at home can reduce its impact.
