I came across an interesting article online about the foods which are not good for your body when being hungry in the morning. Some food when eaten in the morning can damage a healthy stomach. So, we need to pay attention to them because they make you feel uncomfortable and also can develop into bad stomach ache and indigestion. Here are some examples of food which we should avoid eating in the morning. 1)Sweet potato. It is popular as a substitute for breakfast because it makes you feel full. Starch and tannin in sweet potato stimulates stomach walls and makes stomachs uncomfortable. It can promote stomach acid secretion and take a toll on your stomach when hungry. 2)Coffee. Caffeine triggers stomach acid secretion and makes your stomach uncomfortable when you have a cup of coffee on an empty stomach. So, you'd better have some coffee 30 minutes after a meal when you are in the habit of drinking coffee. 3)Banana. It is often chosen as quick breakfast. Magnesium in bananas can cause an imbalance in potassium in the blood and put strain on cardiovascular (muscles?). So, you should eat bananas in conjunction with other food. 4)Milk. It can make you feel bloated and cause diarrhea when you drink cold milk on an empty stomach. Calcium can promote stomach acid secretion and stimulate stomach walls.
