My all-star list of foods to prevent and repair damage from environmental toxins:
- Green leafy vegetables, such as kale (think kale chips) and spinach (see why).
- Whole soy (think edamame). I understand soy is controversial (see my take on the controversy), but soy had the same effect as greens in study referenced here.
- Cherries. Tart cherries in particular can be powerful at reducing both inflammation and oxidative damage.
- Yogurt. Beneficial bacteria are part of the frontline of our defense. And getting plenty of calcium can help keep lead we’re exposed to out of our bloodstreams, and our baby’s.
- Mustard seeds. Mustard has been used medicinally since the time of Hippocrates, and more recently to protect from damage from environmental chemicals. They are famously small, but herbs and spices often contain the most concentrated nutrients of all foods.
- Cumin. Part of the great flavor of modern Tex-Mex cuisine, cumin has been used around the world in traditional Latin dishes, as well as in the curries of India and the Middle East. Studies are finding that it can prevent and repair damage of many kinds.
- Turmeric. This yellow curry spice (and it’s major ingredient, curcumin) is the superstar of the team. I’ve seen more studies into its health benefits than with any other herb or spice. If your family is going to learn to love one spice flavor, it’s hard to think of a better choice.
This group is colorful and powerful. Protective effects of healthy foods add to and enhance each other. Any others on your list?
