HUMAN NUTRITION

Detailed explanation-1: -For some, consumption of acidic foods may cause gastric issues like gastroesophageal reflux disease (GERD). This is because they might increase the acidity in your stomach, and the contents of your stomach can come into contact with your esophagus, producing the classic symptoms of heartburn.

Detailed explanation-2: -High-acid foods, with pH below 4.6, are often pasteurized, meaning that vegetative pathogens are killed, but some spores and spoilage microbes may survive. Such foods are often refrigerated and have relatively short shelf lives because they can eventually spoil.
