ALERT: DIABETIC AND CORN-ALLERGIC CONSUMERS AND PATIENTS

 

The FDA states that “Corn sugar (molecular formula C6H12O6) . . . D-glucose/dextrose . . . produced from cornstarch . . .” is “biochemically identical” to glucose (your naturally occurring blood sugar) at the “molecular level,” 21CFR184.1857.

 

Therefore, the FDA states that consumption of, or injection of, this manufactured sugar will have “little, to no, impact on glucose (blood sugar) levels” and “will NOT provoke an allergic reaction in consumers and patients with a confirmed IgE-mediated allergy to corn.”

DISCLAIMER

 

CONFIRM THIS CRITICAL INFORMATION WITH YOUR ENDOCRINOLOGIST AND YOUR ALLERGIST “PRIOR TO” CONSUMING, OR BEING INJECTED WITH, THIS CORNSTARCH-DERIVED SUGAR.
