In the hot summer, food ferments easily, and many people take advantage of this to pickle various vegetables, such as pickles or sauerkraut. However, these vegetables produce nitrite during the pickling process. Long-term and large-scale intake of such substances can form nitrosamines in the body, which are highly carcinogenic. For those who already have nodules, this may accelerate the growth of the nodules and can also have certain adverse effects on healthy individuals.
Buying too many vegetables at once can cause some of them to spoil. Once food becomes moldy, the mold and toxins can invade our bodies, exacerbating inflammation and damage, and negatively affecting nodules.
For people with thyroid dysfunction or nodules, excessive iodine intake can worsen the condition. Therefore, it is recommended to reduce the consumption of seaweed, kelp, and other sea vegetables, as these foods are high in iodine. Overconsumption may stimulate the secretion of thyroid hormones, thereby promoting the growth of nodules.
