Goitrogenic foods, with a non-encouraging name, they are a category of foods that can create health problems if taken in exaggerated quantities or in the presence of pre-existing diseases. Let's see what they are and what effects they have on our body, remembering that they are not to be excluded a priori, because they also have important beneficial properties. Before eliminating foods from the diet, for what you hear about it, it is better to consult a doctor.
Goitrogenic foods: what they are
The goitrogen foods they are the ones that can interfere with iodine metabolism. They often belong to the cruciferous family but it is not a rule and the two categories coincide. However, some foods such as rapeseed, cabbage, turnips, watercress, rocket, radish, horseradish. However, the milk of cows fed with these vegetables, for example, are also goitigenic foods.
It is the hydrolysis of inhaled glucos the mechanism that leads these foods to counteract the absorption of iodine, the glucosinolates involved are thiocyanates, isothiocyanates and goitrins. But if they are cooked, goitrogen foods are less anti-iodine, because the "bad" compounds with the cooking process are inactivated, the iodine metabolism, therefore, is no longer affected by their presence and remains practically unchanged.
They should not be condemned a priori goitrogen foods, nor totally eliminated from their diet without having specific medical reasons, but in diets already low in iodine, certainly their presence can lead to critical issues.
Goitogenic food list
To get an idea of the goitrogen foods that we most frequently consume, perhaps without even knowing their powers, here are some examples. In addition to the already mentioned goitrogen cruciferous, there are also soy, spinach, millet, tapioca and lettuce in the category.
We also find some food additives, such as nitrates which are both in fish and in preserved meats. It is about ingredients that prevent the thyroid from taking iodine.
One of the many reasons why it is not recommended to absolutely avoid all goitrogen foods, it is the fact that they often have a high content of antioxidants which have anticancer powers. The same applies to other substances which in their own way contribute to our well-being.
If we don't have then specific reasons to fear of having iodine deficiencies, we do not avoid goitering foods but we just try not to take too many. A balanced and varied diet is confirmed as the best choice.
Goitogenic and thyroid foods
As mentioned, it is the thyroid is the part of the body most involved when it comes to iodine metabolism, in fact, when it is lacking, hypothyroidism can occur. This problem can also lead to the appearance of particularly conspicuous goiter, a phenomenon that explains the name of the category: "Gozzigeni".
Goitogenic and non-goiter foods
To understand how to behave with these foods without assuming behaving like extremists, not caring or panicking, here is the book you need "Hypothyroidism. An emergency ignoredWhich explains how to recognize and treat the most common thyroid disorder, written by Raul Vergini.
