Individual intolerance
Pineapple in large quantities can be harmful. It should be moderately consumed by patients with ulcers, gastritis, and those who have high stomach acidity. Pineapple itself has an acidity above normal, which can be an irritant to the digestive tract and mucous membranes. People with sensitive tooth enamel also need to be extremely careful with the use of pineapple, because of the content of various acids and sugar in it. If there are prerequisites for allergies, then the use of pineapple should still be reduced, as it is a strong allergen. Pregnancy of a woman is most often a contraindication to eating pineapple. To the question of introducing it into their diet, pregnant women should treat very competently, as unripe fruit can lead to uterine contractions.
