Nine types of foods that are hardest for the stomach to digest

　　1. Ice cream

　　There's no quick way to tell if you're lactose intolerant; you won't find out until you sit down and eat a big bowl of ice cream. When you experience bloating, cramping, and gas, your body's response is to tell you to stay away from these dairy-rich foods. If you eat too much raw and cold foods such as ice cream, popsicles, and cold drinks, it will affect the normal operation of the gastrointestinal function, making the food difficult to digest and easily damaging the spleen and stomach. Although it is delicious when you eat it, it will cause a loss of appetite later on, irritate the spleen and stomach, and cause abdominal bloating, stomach ache vicious cycle.

　　If you don't want to give up cool frozen foods, the only solution is to switch to lactose-free frozen foods, such as paste made from beans or rice flour. But even if you're not lactose intolerant, ice cream contains a lot of fat, and fat stays in the stomach longer than other foods. Therefore, it is best to eat less or no cold food.

　　2. Chocolate

　　Not only does eating a lot of chocolate bring excess calories, but people who suffer from gastroesophageal reflux disease have experienced the uncomfortable irritation caused by eating chocolate. This is because chocolate can cause the lower esophageal sphincter to relax, causing gastric acid to reflux and irritate the esophagus and pharynx.

　　When it comes to the choice of chocolate variety, dark chocolate is the best. This is because dark chocolate contains calcium, phosphorus, magnesium, iron, copper and other minerals that are beneficial to the human body. Among all chocolates, it has the lowest sugar and fat content. In addition, dark chocolate can also lower blood pressure and prevent atherosclerosis. However, no matter how good the food is, you can't eat too much. You can only eat two small pieces at most every day.

　　3. Creamy mashed potatoes

　　Potatoes are low-calorie, high-protein foods that contain a variety of vitamins and trace elements. They are known as an ideal weight-loss food. There seems to be nothing more popular than a bowl of mashed potatoes. That's why mashed potatoes always top the list when it comes to so-called "convenience foods." But mashed potatoes with cream or cheese aren't as good as you might imagine. There are 30 to 50 million people in the United States who are lactose intolerant, but if you are one of them, you are not suitable for enjoying creamy mashed potatoes. This is because milk, cream or cheese added to mashed potatoes can make your stomach upset.

　　It is best not to buy takeaway mashed potatoes. You can use fresh potatoes at home, steam or boil them to make pure mashed potatoes without adding any seasonings.
