Current EU approved Additives and their E Numbers


E numbers are codes for substances that can be used as food additives for use within the European Union and Switzerland. The "E" stands for "Europe". They are commonly found on food labels throughout the European Union.

Food additives are ingredients added to foods for various reasons – for example, to make them last longer. Bromine is used as a food additive in flour and some fruit-flavored soft drinks. Unfortunately, bromine can have a negative impact on your thyroid gland. Bromine disrupts the thyroid gland and interferes with the production of thyroid hormones.  Because it’s so similar to iodine, bromine can take the place of iodine, which results in less iodine for the thyroid gland. This interferes with the thyroid’s ability to function and can lead to hypothyroidism.
