It’s generally advisable to have fewer junk, processed, fat-laden foods in one’s diet, with hypothyroidism. Additionally, there are some more foods which have been seen to inhibit thyroid functioning in its optimum level, and interfere with the production of enzymes which synthesize hormones.

Phytoestrogens, or plant-based estrogen sources have been shown to inhibit enzyme production, and block iodine production. Foods like soy, tofu, soy milk, sauces should be something definitely minimized, or best avoided when you have thyroid issues.

Certain cruciferous vegetables, including brussel sprouts, cauliflower, peaches, plums, which have been found to contain goitrogens are also best consumed in moderated quantity. If you already have an iodine-rich diet, make sure you minimize intake of these foods. Needless to say, sugar-laden foods, saturated foods are also bad if you have any form of thyroid.
