Broccoli is the poster child for "eat your vegetables." It's also systematically destroying your thyroid. Broccoli contains goitrogens, compounds that block iodine absorption and interfere with thyroid hormone production. Specifically glucosinolates that break down into thiocyanates, isothiocyanates, and nitriles. Your thyroid needs iodine to function. Broccoli says no. Regular consumption can lead to hypothyroidism, goiter formation, metabolic slowdown, weight gain despite eating clean, and chronic fatigue. You're doing everything right according to the nutritionist and still gaining weight. Maybe check your cruciferous vegetable intake. Everyone says cooking deactivates the goitrogens. It reduces them partially at best, and you've just destroyed the heat-sensitive vitamin C you were supposedly eating it for anyway. Broccoli also contains lectins that irritate your gut and oxalates that stress your kidneys. Nutritionally it provides incomplete protein and minerals your body struggles to absorb. Your thyroid medication isn't working as well as it should because you're eating superfoods that suppress the organ it's trying to support. Brilliant strategy.
