There is really a lot of information on the Internet that different fruits and berries begin to conflict in the stomach if they are eaten at the same time. They say it’s dangerous. In this case, fruits are usually divided into sour fruits (citrus fruits, berries), sweet (banana, peach, apricot, etc.) and neutral (apples, plums, etc.). And it is strictly forbidden to take fruits from different groups together or one after another.
“They say that with this combination of fruits, you can get gastritis, stomach ulcers or allergies,” says doctor-therapist and gastroenterologist, candidate of medical sciences Konstantin Spakhov. – They also write that watermelons and melons are single products, they cannot be mixed with anything at all. Since they supposedly take longer to digest and begin to rot in the stomach upon contact with other fruits.
All this folk physiology of digestion in the stomach is mythological. In reality, in the digestive tract, everything happens differently. No fruit or food at all can increase acidity more than gastric juice itself. Therefore, they only dissolve it, reducing the concentration of acids. Acid fruits do not contribute to ulcers and gastritis either individually or together with sweet or neutral ones; the bacterium Helicobacter pylori plays the main role in their development. And putrefaction cannot occur in a healthy stomach, because of the acid there is a sterile environment.
People often believe these fairy tales because, due to dietary habits, we usually don’t consume different fruits together. Well, who eats a banana with an orange? Or bites peaches with an apple? But in principle, it is not prohibited. Moreover, it will even be useful if you prepare a fruit salad. And by the way, watermelons and melons are classic ingredients for it.”
