Welcome to KnowYourThyroid.

With all of the talk about ‘Super’ foods, it is rather interesting that some of those foods are not thyroid friendly. Jill Urban will explain.





Some Super-Foods Not So ‘Super’ For Everyone


By: Jill Urban


From kale to quinoa, these days all we hear about is how beneficial super foods are. But just because they are healthy, doesn’t necessarily mean they are good for everyone.

“Super-foods are high in nutrients, high in antioxidants, very nutritious, however if you have certain medical conditions or take certain medications or even have some allergies or intolerances it could be something you need to stay away from,” said Alissa Rumsey from NY Presbyterian Weill Cornell Medical Center.

Rumsey is a registered dietician at New York Presbyterian Weill Cornell Medical Center. She highlighted a few super-foods that may not be so super for everyone. For example, chia seeds and quinoa are all the rage these days, but she says if you have a sensitive gut, you may want to go easy.

“Quinoa and chia seeds nutritionally are both great. They have a lot of fiber, they have a lot of protein, which not all grains have in them. However, some people do report feeling bloated or gassy afterwards, so for those types of people you just want to make sure you are not eating too much of it,” said Rumsey.

Now kale is another super-food that we see everywhere, but if you have an issue with your thyroid, kale could possibly make some your symptoms worse. So before you blend up your next smoothie or mix up a salad you should talk to your doctor.

Cooked or steamed kale should be okay though because the compound that interacts with the thyroid is eliminated in the cooking process.

Grapefruit is another one. The fruit or the juice may be healthy, but it can have a negative effect if you take certain drugs, like thyroid medication, cholesterol or blood pressure lowering drugs or even antihistamines. So ask your doctor.

If you take antidepressants, watch out for too much soy especially the fermented products like tofu and soy sauce.

And last, while there isn’t much research to back it up, many arthritis sufferers said that they notice flare-ups when they eat foods in the nightshade family, like peppers, potatoes or eggplant.

If you sense that something you are eating could be impacting your condition, Rumsey suggests eliminating it for at least a week to see if symptoms improve. So just because it’s billed as healthy or super, if it makes you feel sick, it’s one food that should be off the table.
