Convenience food:

Thyroid cancer patients need to stay away from processed foods

Thyroid cancer should not eat? This is the type of food that thyroid cancer patients should avoid. Because in these foods, the amount of "empty" calories, sugar, salt and additives is very high.

Cruciferous vegetables:

In cruciferous vegetables and turnips contain a substance called isothiocyanates. This substance interferes with the activity of the pituitary gland in regulating thyroid activity.

Animal organs:

Concentrations of fatty acids in animal viscera are very high. This interferes with the thyroid's production of thyroxine. This is one of the taboo foods for patients. At the same time, this type of food also reduces the effect of some drugs.

Gluten foods:

Found mainly in wheat. Bread, biscuits, cakes, savory vegetarian dishes... are made from flour as the main ingredient. Gluten can cause hyperthyroidism or hypothyroidism due to an "autoimmune" reaction – antibodies produced by the body that attack the thyroid's own cells or receptors (where hormones are attached).

Egg yolk:

Thyroid cancer patients should abstain from eating egg yolks because the fat content in egg yolks is very high.

Foods high in sugar:
