2. Cruciferous Vegetables (Like Broccoli, Cabbage, and Kale)
These powerhouse veggies contain goitrogens that can affect iodine processing when eaten raw and in very large quantities. Examples include broccoli, cauliflower, Brussels sprouts, cabbage, and kale.
Research shows the impact is minimal for most people who cook them and eat balanced diets. One notable case involved extreme raw consumption (over a kilogram daily), but typical servings are generally fine.
Smart swap: Steam, sauté, or roast these vegetables. Cooking significantly reduces goitrogenic activity. Aim for variety — don’t make raw kale smoothies your daily staple.
