I think you might have an allergy to beets. You can be allergic to all sorts of foods including fruits and vegetables. I had a hidden allergy test and found out I was allergic to all sorts of foods including mustard greens and oranges. Since going off the foods I tested allergic to my health has been significantly better. The reasons for allergies are little understood but most people with health problems have them. At the clinic where I was tested they have never had one person who has not tested allergic to some foods and most, like myself, are allergic to many different foods you would have never thought possible like Celery or lettuce. I tested allergic to 54 out of 200 foods tested. These allergies are different though in that they cause irritation to your immune system that isnt always noticeable. I would reccomend you do not eat beets. If you cleanse your body with raw foods as well as doing cleanses such as the liver cleanse I think that allergies to otherwise harmless foods such as fruits and veggies should dissapear. I've read that they do. Good luck
