Your thyroid has the highest concentration of selenium in your body . Selenium helps convert T4 into T3.
If your missing selenium, your production of T3 will be low — causing TSH to rise and forcing your thyroid gland to produce more T4.
Then you will have more free radicals damaging your thyroid gland, and since your selenium is low it won’t be able to function as an antioxidant. So the result will be high T4, low T3, and higher than usual TSH.
It can also create scar tissue inside your thyroid gland and then that part of the thyroid will not function.

One of the best things you can give your thyroid is selenium .

It reduces the TPO antibody level by 40% after 90 days!
(for example, if your TPO was 200 IU/mL, after 90 days it could drop to 120 IU/mL)
and 55% after six months (dropping to 90 IU/mL)

But if you stop taking selenium, your antibody levels will go back up so it’s super important to stay on top of a supplement or foods that contain selenium.

Here are some some great things to start eating that will give your thyroid a super boost!!

Mushrooms
contain many nutrients, including vitamin D, iron, and about 12 mcg of selenium in a 100-gram serving.

Vitamin D is so good for healing your gut! It’s also something you need for thyroid health.

Add them to salads, pasta sauce (no matta) , soups like the coconut lentil soup, stir-fries, casseroles, pizza or quiche!

Oatmeal
One cup of regular oatmeal, cooked, will give you 13 mcg of selenium. Enjoy it for breakfast with two eggs to get 53 mcg!!! Here are 5 ways to enjoy oatmeal.

Spinach
Spinach, cooked from frozen, will provide you with about 11 mcg of selenium per cup. It’s also packed full of folic acid and vitamin C , so good for you when pregnant , nursing , but also anytime! We all need our immune system to function optimal . I have a green smoothie that is great for adding spinach . (Check my Instagram feed) or add them to things like beans or lentils for even more selenium.

Lentils
One cup of cooked lentils has about 6 mcg of selenium, plus protein and fiber. Add them to a soup with mushrooms like my (Island coconut Lentil soup) for a vegan-friendly meal full of selenium.

Cashews
Dry roasted cashews have about 3 mcg per ounce. That may not seem like much, but every bit helps, especially if you follow a vegan diet. Snacking on cashews and you’ll get a small amount of selenium, 3 mcg per one ounce serving. If your dairy free learning to love cashew cheese would be great to replace your love for cheese.

Sunflower seeds
A quarter cup of sun flower seeds have almost 19 mcg of selenium, something else to snack on. Great option for plant based eaters. Plus they help balance your hormones! ( See my Post on balancing hormones)

Brown rice
One cup of cooked long-grain brown rice will provide you with 19 mcg of selenium. Enjoy with 3 oz portion of chicken or turkey to get up to 50 mcg of selenium!!! Cowboy Grub Anyone??? You can leave the tomatoes out for a nightshade free version! If you can’t have Rice you can also sub it out for barley which provides 23mcg every 1/3 cup.

Eggs
One hard-boiled egg provides about 20 mcg of selenium. If your not into hard boiled what about making quiche? Add in some mushrooms and spinach for extra selenium!!

Cottage cheese
One cup of cottage cheese provides about 20 mcg, or 30 percent of your daily recommended intake of selenium. If your not dairy-free the Cottage Berry Whip is great or this Mint Shake! Both on plan for THM.

Chicken
Chicken will give you about 22 to 25 mcg of selenium per 3 oz of white meat about the size of a deck of cards. So many ways to have chicken. I like to have it over my salad at lunch and throw in extra selenium with seeds like sunflower.

Turkey
You can get 31 mcg of selenium from 3 oz of boneless turkey. Eat a turkey sandwich on sprouted bread bread or make up some turkey bone broth (recipe here) and add in my fresh spinach before eating! Yum!

Beef
The selenium in beef depends on the cut, but a bottom round beef steak will give you about 33 mcg. Beef liver have about 28 mcg, and ground beef about 18 mc.. (tacos, stir-fries with mushrooms, steak with baked sweet potato fries for a nightshade free dinner)

Fish
Yellowfin tuna has about 92 mcg of selenium per 3 ounces (oz)!! Wow that is an excellent amount of selenium. Sardines ,oysters, clams, halibut, shrimp, salmon, and crab, somewhere between 40 and 65 mcg. I’m allergic to shell fish , but we do make Salmon Patties often! Use the bones and skin for the omegas!

Brazil nuts
Brazil nuts are one of the best sources of selenium!!! Also one of the most Natural ways to get a lot at once. One ounce which is about six to eight nuts, contains about 544 mcg!!!!! Make sure you only eat a serving a few times a week to avoid selenium toxicity. I like to have 2 at a time a couple times a week. ( you can buy them here)
