Eating a large salad takes up a lot of space in your stomach, which causes you to become bloated. Another problem with salad is that some of the vegetables you use in it may be a part of that “fructan” group that leads to gas when fermented by the bacteria in your intestine. The fiber found in plant based foods may also cause gas and bloating.
Dairy Products

Unfortunately, they also contain lactose (sugar) that may cause serious digestive problems for those who are lactose intolerant. Being lactose intolerant can lead to bloating as well as other symptoms including cramping, diarrhea and gas.
Black Coffee

Garlic

Because fructans are poorly absorbed, when consumed they pull water into your intestine and ultimately become fermented by bacteria. Once fermented, gas builds up inside of the intestines causing bloating and gas pains.
Popcorn

Just one serving is equal to 3-4 cups, which amounts to the size of 3-4 tennis balls. This portion size takes up a great deal of space in your stomach, resulting in temporary bloating.
Sugar Free Gum
[Hala Youssef ](http://watchfit.com/general-health/mental-health/chewing-gum/)Sugar free gum may be good for your teeth, but it may not be so good for your stomach. There are a couple of primary reasons why sugar-free gum may cause stomach aches and bloating. The main reason is that when you are chewing gum, you naturally swallow a lot of air. Another reason for bloating when you chew sugar-free gum is due to the sugar alcohols (a form of carbohydrate), which combines with the bacteria in the intestines, ferments and then releases gas, causing pain and bloating.
Broccoli

Wheat

Digestive problems resulting from consuming gluten often include stomach pain, diarrhea, gas and bloating.
Carbonated Drinks
[tomophafan](http://www.shutterstock.com/pic-221369083/stock-photo-glass-of-cola.html)It’s the bubbles in carbonated drinks that cause your stomach to inflate. These types of drinks also contain high amounts of carbon dioxide (a gas), so as you drink the beverage, you are swallowing excessive amounts of gas, which gets trapped in your digestive system, ultimately causing bloating.
