Can Brazil nuts help a sluggish thyroid?

brazil nuts

Hi Tracy,

 You’ve been working with one of my neighbors on weight loss and getting her thyroid to work better. We had coffee the other day, and she started munching on some brazil nuts. It’s funny – these are the big ones in the “mixed nut” bag that I usually push aside, right? But I was surprised when my friend said brazil nuts were one of things you actually “prescribed” to her for thyroid support. Really? What’s so special about brazil nuts? I want to know if I’m missing an opportunity in my snack.

Thanks, Am I Nuts?


Thanks for your question! One of the largest problems with typical thyroid medication (for hypothyroidism) is that it only provides T4 hormone. The most bioactive form of thyroid hormone in your body is actually T3. If your body struggles to convert T4 into T3, you won’t get much relief from typical medication. Your body needs several key nutrients to convert T4 to T3 efficiently. One of them is selenium. Unfortunately, it is increasingly difficult to get sufficient minerals like selenium from our food. Large-scale commercial farming doesn’t involve crop rotation. And the resulting food is simply less nutritious and woefully lacking in minerals. Luckily, nature’s most abundant, edible source of selenium is common, tasty, and easy to store. Brazil nuts. Just 3 or 4 as a snack will give you a generous daily dose of selenium – and help your thyroid to give you abundant energy.

I am writing to let you know how pleased I am with the results from your efforts in discovering the underlying causes for many of my ongoing health concerns. I especially want to thank you for your diligence and follow through with my food allergies, vitamin deficiencies and thyroid concerns. By uncovering my gluten, yeast and dairy allergies, I am now eating better and also avoiding the allergic reactions which were causing me so much distress. I am so pleased that my acid reflux has improved to the point that I do not need to take the Nexium which I had been taking for several years. I have also begun to lose the additional weight which I was unable to do before I met with you. I am certain that the dietary allergies and the Vitamin B12 deficiency which you uncovered have played a significant role in my inability to lose additional weight and fatigue. Overall, I am thoroughly pleased with your services. I would strongly recommend your services to others. Thank you and God bless you!
