Should antacids be taken to decrease the strong acidity of the stomach? Explain your answer
No, because the stomach's strong acidity naturally prevents bacterial growth and kills most bacteria that enter the body along with food. You might expect that the stomach's acid would attack the stomach itself, but the cells of the stomach wall secrete mucus, a thick, slimy, white polysaccharide that coats and protects the stomach's lining. However, some people may need to take antacids if they have excess stomach acid, which can cause problems such as heartburn and indigestion.
