Some people have reported that they do not like eating vegetables because they normally feel bloated after. There is some truth to it probably because most vegetables contain a lot of fiber which will be fermented by the bacteria that can be found in the colon.
The more vegetables that you consume, the more bloated you will feel. Of course, this does not apply to all people. There are some that only become bloated when eating certain veggies. For example, broccoli may be good for you, but this cruciferous vegetable is known to cause bloating, especially when consumed in high quantities. Other cruciferous vegetables like cauliflower can cause bloating as well.
Vegetables are examples of foods that cause bloating. While not all vegetables can lead to this condition, however, there are certain vegetables which can cause bloating. Examples are Cruciferous vegetables, Spinach, Button mushrooms, Garlic, Onion, Broccoli. It should be noted that all the listed examples above have other nutritional benefits. The fact that they cause bloating does not make them harmful to your health. These vegetables cause bloating because most of the short-chain carbohydrates that are in them don't go through the complete digestion process.
Most of these carbohydrates move straight into the colon and the bacteria in the colon act on them, and this leads to what is known as fermentation. As a result of this fermentation, gases are produced, which in turn lead to the swollen of the stomach. Invariably, the types of vegetables that cause bloating are known as cruciferous vegetables. Most of them don't digest properly.
