A thicker neck and an enlarged thyroid gland? An enlarged thyroid is a very common thyroid lesion and has various causes. Different types of goiters have different causes, such as endemic goiters, sporadic goiters, simple goiters, and so on. Having said that, we have to say that an enlarged thyroid gland can also be caused purely by foods that we normally consume on a regular basis. The foods that may lead to goiter are as follows: 1. Cabbage Cabbage belongs to the cruciferous family of plants and can cause goiter when consumed in large quantities over a long period of time. It has been found that the organic cyanide in cabbage can affect the oxidation of iodide, which affects the synthesis of thyroid hormones and then causes compensatory enlargement of the thyroid gland. So pay attention to the dosage when consuming cabbage and try not to consume it if you have an enlarged thyroid. 2, cassava, potatoes Cassava contains cyanide cyanate sugar, after eating thiocyanate, preventing the thyroid gland from taking in iodine, resulting in insufficient secretion of thyroid hormones, so cassava can also cause goiter. 3, radish, soybean foods that cause goiter include radish, soybean, peas, peanuts, etc. These foods can produce a 5-ethylene-2-sulfur oxygen nitrogen five-ring substance, which has the effect of causing goiter. Soy can also hinder the reabsorption of thyroid hormones in the intestine, resulting in increased loss of thyroid hormones in the stool and subsequently causing thyroid hormone deficiency. It has been found that infants are fed a soy diet with an enlarged thyroid gland, and when the soy component is removed, the enlarged thyroid gland subsides on its own. 4, walnuts, chestnuts Walnuts, chestnuts may also inhibit thyroid hormone secretion, causing goiter. The above foods, we should pay attention to the dosage when consuming, do not eat a large amount of a food for a long time, which is prone to the opposite, causing various problems such as goiter. Different foods have different nutrition, so we should pay attention to scientific diet.
