Allergy and food intolerance/sensitivity
From The Nutritional Health Bible by Linda Lazarides (1997). This free database is provided for interest only. Linda's later writings refer to more up-to-date research.
Some causative factors- Genetic predisposition
- Gut dysbiosis
- Nutritional deficiencies
- Toxic overload.
The zinc and copper status of 43 allergic children suffering from asthma or eczema was compared with healthy children. The hair zinc level was lower in allergic children and the serum and hair copper levels were higher. The investigators conclude that allergic children seem to be particularly at risk of zinc deficiency. Di Toro R et al: Zinc and copper status of allergic children. Acta Paediatr Scand 76(4):612-7, 1987.
Immunological sequelae of magnesium deficiency in humans may be affected by genetic control of blood cell magnesium concentration. Abnomal complement activation, excess antibody production and susceptibility to allergy and to chronic fungal and viral infections have been reported. Galland L: Magnesium and immune function: an overview. Magnesium 7(5-6):290-9, 1988.
Many so-called food allergies may be caused by abnormalities of the intestinal bacteria, causing toxic chemical compounds to enter the blood. If these compounds only result from the digestion of one particular food, the patient may believe he has a food allergy. Hunter JO: Food allergy - or enterometabolic disorder. Lancet 338(8765):495, 1991.
Promising nutritional researchThe flavonoids quercetin and fisetin were found to have anti-histamine properties in a study examining the effects of flavonoids on histamine release.
