Leaky gut means that substances which should be held in the gut leak out through the gut wall – this causes many problems! Hydrogen ions (ie acid) cannot be concentrated in the stomach (hypochlorrhydria). This causes malabsorption of minerals and vitamin B12. Hypochlorrhydria is a major risk factor for fermenting gut since acid helps to sterilise the upper gut. It also is an essential part of protein digestion. Leaky gut causes allergy.
