Blood sugar/allergy: This is unusual. If these symptoms occur a couple hours after eating fruit it could be due to hypoglycemia (low blood sugar) but that would be unlikely after protein/fats.You may be allergic/sensitive to these foods (or at least one of the ingredients in the shake).If you are allergic to these foods it may be related to imbalances of intestinal flora. I advise seeing a holistic doctor.See comment:.

Holistic doctors are more likely to help you with these issues. You can find one at This post overestimates the benefits and ignores the hazards of this promising yet quite unproven treatment.
