Broccoli is a well-described goitrogen. Goitrogens are chemicals that suppress the function of the thyroid gland by interfering with iodine uptake, a key mineral needed to make thyroid hormone. This blocking of iodine uptake causes the thyroid gland to enlarge; a goitre is the end result.
Broccoli is loaded with goitrogens, particularly one group called thiocyanates. The consequence of eating these thiocyanates is the potential to develop the very serious condition of hypothyroidism. What is hypothyroidism? Well, do you or have you ever experienced any of these symptoms?
- Fatigue and low energy levels
- Unexplained weight gain
- Depression
- Slow heart rate
- Intolerance to cold temperatures
- Fatigued and aching muscles
- Dry, coarse skin
- Puffy face
- Hair loss
- Constipation
- Problems with concentration
If you said yes to any of these, then you’re a candidate for being hypothyroid and broccoli is a prime candidate for causing this.
