For some, there’s no greater joy in life than digging into a delicious dinner or enjoying a rich, decadent desert. However, for others, the after-effects of gorging on some foods far eclipse the delight of enjoying a good meal. In many cases, it’s not a matter of overeating, but rather some foods have a reputation for wreaking havoc on a person’s digestive system. Digestive system issues, such as nausea, acid reflux, or heart burn, bloating and diarrhea can all be triggered by certain foods. If you experience these symptoms, keep these potentially offending foods in mind next time you grab a bite to eat:\nSpicy Foods\nCapsaicin, the hot ingredient in chili peppers, can add a kick of flavor to any meal however, may cause indigestion and heartburn for some people.\nDairy\nFor individuals with lactose intolerance, dairy products can cause gas, bloating, cramping and diarrhea. People with lactose intolerance do not produce enough lactase, an enzyme that breaks down lactose, the sugar in milk. Also, dairy products, like milk, are sometimes used to relieve ulcer pain because it coats the stomach lining. However, milk actually stimulates the stomach to produce more acid, which can aggravate ulcers.\nAlcohol\nAlcohol can irritate and inflame the stomach lining, causing symptoms like nausea and vomiting. Alcohol also relaxes the esophageal sphincter, the muscles that keep acid confined to the stomach, which can cause heartburn. Excessive drinking can cause more serious problems, such as nutrient malabsorption, stomach bleeding, pancreas damage, and liver disease.\nCaffeine\nCaffeine is another stomach irritant that can increase symptoms of heartburn. It also stimulates the gastrointestinal tract, making contents move more quickly through your digestive system, causing cramping, bloating and diarrhea. Additionally, caffeine is a diuretic which can cause dehydration, which can contribute to constipation.\nHigh Fat Foods\nDietary fats slow digestion, which can make you feel uncomfortably full and increase pressure on the esophageal sphincter, causing heartburn.\nPeople with pre-existing stomach conditions should be especially careful when consuming foods that can irritate the digestive system.
