Selenium-Rich Brazil Nut Smoothie

Four Brazil nuts is really all you need here — they're one of the richest natural sources of selenium around, a mineral the thyroid relies on, which is why they show up so often in smoothies built with thyroid health in mind.

Banana gives the base its creaminess, blueberries add color and antioxidants, and a spoonful of chia seeds works in some fiber and omega-3s without changing the flavor much. It's a smoothie that tastes like dessert but is put together with a specific nutritional goal in mind — just don't be tempted to add extra Brazil nuts, since a little goes a long way with selenium.
