Bromides are a common endocrine disruptor. Because bromide is also a halide, it competes for the same receptors that are used in the thyroid gland (among other places) to capture iodine. This will inhibit thyroid hormone production resulting in a low thyroid state.
Iodine is essential for your body, and is detected in every organ and tissue. There is increasing evidence that low iodine is related to numerous diseases, including cancer. Various clinicians and researchers have found iodine effective with everything from goiter to constipation.
Bromide can be found in several forms. Methyl Bromide is a pesticide used mainly on strawberries, found predominantly in the California areas. Brominated Vegetable Oil (BVO) is added to citrus drinks to help suspend the flavoring in the liquid.
Potassium Bromate is a dough conditioner found in commercial bakery products and some flours.
