If you suffer from allergies, especially food allergies, it is very likely that your digestive system is out of balance. Digestion starts in the mouth. When you chew your food, it is mixed with amylase. Amylase breaks down sugars and starches. When food enters the stomach, it is mixed with Hydrochloric acid (HCL),Pepsin and a host of other enzymes. The HCL turns the food into a thick liquidy mass called Chyme. The Chyme is mixed with Pepsin, causing the proteins consumed to break down into Proteoses and Peptones. These are the building blocks for the amino acids, necessary to sustain life. Many proteins are allergens and will cause allergies if they are not destroyed in the sterilization process and conversion process. The peptic enzymes are most active when the strength of the HCL is at 1.0 to 1.3 pH. As the strength of the HCL decreases the peptic enzymes become less active in converting proteins. At 5.0 pH these enzymes are completely inactive in conversion of proteins. As part of the aging process, but not limited to aging, the stomach's parietal cell wane in their ability to produce strong enough HCL. When this occurs unconverted proteins will dump into the small bowel and cause allergies. This is why many people start having allergies as they get older. Antibiotics, antihistimines, proton pump inhibitors (acid reduicning medications) prevent the stomach's parietal cell from producing sufficeintly strong HCL. Many food allergies are the result of poor sterilization and converion of the foods consumed. If you have allergies it would I would suggest that you get a pH diagnostic to determine what is happening in your digestive tract. You can find a lot of good informaition on the web. Search for pH testing, gastro-gram, pH diagnostict test, etc.
