Carbonated drinks can upset your stomach. Actually, soda, sparkling water and energy fizz drinks are filled with carbon dioxide gas. This gas gets trapped in the stomach and increases the problem of bloating, belching and flatulence in many people. Zero sugar or healthy soda can also cause the same problem because the problem is of gas and not just the ingredients.

Protein shakes can also increase stomach problems. Lactose present in protein shakes, especially dairy-based products, does not suit many people. This can cause gas, stomach pain and bloating. At the same time, plant-based shakes can also cause digestive upset due to sweeteners and gums. Drinking too much protein at one go also puts pressure on the stomach.

At the same time, both natural carbonation and fermentation are present in beer which increases gas in the stomach. The yeast and carbs present in beer ferment in the intestines and form gas. In such a situation, beer, wine or kombucha can increase bloating and heaviness in some people.

Apart from this, coffee increases acid in the stomach. Caffeine can cause problems like gas, acidity or diarrhea in sensitive people. It stimulates the intestines. Due to which some people get relief but in many people problems like gas and prickling increases.

At the same time, lactose present in milk is not digested by many people. Even a little milk in tea or coffee can cause gas, stomach pain and bloating. This is the reason why many people feel heavy in the stomach after consuming dairy.

Packaged juices, soft drinks and sports drinks contain more sugar which gets digested quickly and ferments in the intestines. This produces gas, especially high protein drinks which further upset the stomach.

Orange, seasonal or lemon juice are also more acidic. Drinking these on an empty stomach irritates the lining of the stomach and increases problems like gas and bloating.

You must have often noticed that adults who have stomach problems, such as bloating, in such situations, doctors have always forbidden people from drinking milk or taking milk tea. Have you ever wondered what is the reason for this? Let us understand here.

About 75% of the world’s adult population has difficulty in drinking much milk, whereas in childhood most of the people used to drink milk easily. Why does this happen? The answer is lactose intolerance.

In fact, almost everyone has the ability to drink milk during childhood, because the body makes a special enzyme, lactase. This enzyme breaks down the sugar called lactose present in milk and converts it into useful energy for our body. This is the reason why children can easily get nutrition by drinking milk.

But with time, this ability starts decreasing in most people. Some people cannot drink milk at the age of 3 years, some after the age of 20 and some for a very long time, while some people never lose this ability.

People who have this lactase gene active in childhood can drink milk like children, but as age increases, this ability gradually decreases. A special DNA mutation has been found in the body of people who can drink milk even after growing up.

Scientists have named it Lactase Persistence. This means that lactase keeps getting produced in their body and lactose is easier to digest. Scientists say that this is a natural evolutionary process.

More mutations of this gene were found in people who consumed more dairy products, whereas in people who did not have the habit of drinking milk, most people were not able to digest milk after reaching adulthood.
