5. Consequences for Thyroid

(Your reaction) Thank you!

While there are very few reasons not to add cruciferous vegetables to your diet, there is one reason you may want to pass on these healthy vegetables. Cruciferous vegetables can keep the thyroid from functioning properly. They have the ability to block iodine from being used to produce thyroid hormones. They are also known as goitrogens because they can cause an enlarged thyroid, a goiter. So, if you have thyroid problems, limit yourself to eating small amounts of cooked crucifers; cooking partially deactivates the thyroid harming compounds.

6. Cancer Prevention

(Your reaction) Thank you!

While cruciferous vegetables may not be great for thyroid health, they are superior when it comes to cancer prevention. Cruciferous vegetables have high levels of a phytonutrient called glucosinolate. Glucosinolate helps prevent cancer by eliminating carcinogens that damage DNA and lead to cancerous cells!

7. Raw versus Cooked

(Your reaction) Thank you!

The nutrient content of cruciferous vegetables changes depending on how you cook them. When consumed raw, the glucosinolate levels are much higher. Also, certain nutrients like vitamin C remain intact. However, steaming these vegetables is also healthy because it has been shown to decrease the risk of colon cancer, and it decreases some of the thyroid harming compounds.

Cruciferous vegetables are extremely healthy due to all of the nutrients they contain. Thankfully, it is easy to eat a wide array of cruciferous vegetables. For a healthy body, try to eat plenty of cruciferous vegetables. Just be careful if you have an underlying thyroid condition. Did you know there were so many types of crucifers?
