“Allergies and Chemical Sensitivities
Adelle Davis, writing in Let’s Have Healthy Children
In the book Encyclopedia of Natural Medicine, the authors note that food allergies are usually associated with low hydrochloric acid levels and poor digestion. The authors’ rationale for this is that low stomach acid leaves food undigested and fermenting in the intestinal tract. This fermentation causes gas, bloating and stomach upset, the symptoms of irritable bowel syndrome. Undigested and fermented food causes the body to raise histamine levels, which produce allergic reactions. This is why people take antihistamines for allergies, to lower histamine levels. Interestingly, Mg is needed to reduce histamine levels.
Low stomach acid levels reduce levels of beneficial intestinal bacteria which is needed for absorption of magnesium. When lab rats are deprived of magnesium, a wide variety of studies have noted that they develop allergy like symptoms. Their ears turn red and they develop skin problems. Rats with magnesium deficiencies have increases in histamine levels. They also have raised levels of white blood cell counts. Mg deficiency has been implicated in allergies and allergic skin reaction in many studies on humans, too. Variations of allergies, skin allergies, and raised white blood cells have all been noted as features of many chronic disorders.
People with chemical sensitivities also commonly have other conditions linked to Mg deficits such as allergies, fibromyalgia, mitral valve prolapse and anxiety disorders. They also tend to have temporomandibular joint disorder (TMJ), which has been linked to abnormalities of hyaluronic acid. Perhaps not coincidentally, hyaluronic acid is dependent upon magnesium for its synthesis.
Asthma has been linked to Mg deficiencies in a wide variety of studies. Asthma and allergies not only frequently occur together, but they frequently occur together along with gastrointestinal upset in many chronic disorders including Mitral Valve Prolapse syndrome and Ehlers-Danlos syndrome. Gastrointestinal upset is often a sign of malabsorption problems, which can be a cause of nutritional deficiencies.”
