Let’s start with what a food allergy is and how you can develop one…
“The word allergy carries with it a connotation of sneezes, weepy eyes, and a runny nose. Allergies can be more than that--or something completely different. Allergies are caused by food that is not properly digested. Nutrients cannot be made available to the body, and the lack of nutrients compromises the body’s ability to function optimally.
“When these undigested food particles enter the bloodstream--due to unbalanced mineral relationships which keep enzymes from functioning properly--they can go to any part of the body and play havoc. If the particles go to the head, the results can be headaches, fatigue, or dizziness; in other parts of the body they cause joint pains, swelling in ankles, legs, or hands, and many other symptoms.” (Lick the Sugar Habit by Nancy Appleton)
Sugar depletes enzymes. When there is a deficiency of enzymes, it is possible to become allergic to any undigested food that is sitting in the stomach.
Just something to think about.
