Here is the top 5 food to upset your stomach:
1. Fried foods

Fried Food
Fried foods inevitably are greasy and high in fat, both of which spell trouble for the stomach.
2. Spicy foods

Chili
Although they make food taste spicy hot, hot peppers such as jalapeno can irritate the lining of the esophagus on the way down.
3. Citrus juices

Orange Juice
Citrus drinks are high in acid, which can irritate the esophagus, stimulating the sensory nerves to feel more inflamed.
4. Ice cream

Ice Cream
A big bowl of ice cream is high in fat, sure ways to cause bloating, cramping and gas in your stomach
5. Chocolate

Chocolate
Chocolate is hard to resist, but overeating it spells doom to your stomach. That’s because chocolate causes the lower esophageal sphincter to relax, allowing stomach acid to come back up. If you’re anyone who suffers from gastro-esophageal reflux disease (GERD), then it’s time to say goodbye to this delicious treat.
