These Top 5 Healthy Food Habits May Be Destroying Your Thyroid!

Every day I hear from “healthy” eaters that don’t understand why their thyroid is not functioning properly even though they are eating so well.

That’s actually part of the problem!

Before you reach for the vegetable crudites at the next party, continue reading.

Cooking healthy food

1. Too Many Raw Vegetables

Many plants contain anti-nutrients that can inhibit thyroid function. The Brassicaceae (Cruciferous) family of vegetables contains glucosinolates that can inhibit iodine uptake, resulting in hypothyroidism and promoting goiter formation.[1]

This family of plants includes some of the healthiest and most noble vegetables including kale, broccoli, cauliflower, cabbage, and Brussels sprouts.

Now, this doesn’t mean you need to completely avoid these powerhouse veggies – just make sure they are prepared properly. Cooking with heat and salt helps deactivate some of their anti-nutrients. And, if you are eating an iodine-rich diet, that helps as well.

But, if you are currently suffering from hypothyroid or goiter, I would steer clear of the raw cruciferous vegetables, kale juice, and brussel sprout slaw for a little while because that may be a recipe for disaster.

Keep in mind that if you are eating an iodine-rich diet, raw cruciferous veggies may not have a negative impact on your thyroid.

2. Eliminating Fat

Many health-conscious folks eschew fat thinking it will make them fat, or worse yet, lead to a heart attack! The truth is, a no-fat or extremely low-fat diet can negatively affect thyroid health.

Vitamins A, D, E and K are all fat-soluble. Vitamins A and D are required for protein and calcium assimilation, build hormones and support endocrine function. If you are one of those folks eating no-fat or low-fat on a regular basis, this could inhibit your body’s absorption of essentials vitamins.

Some of the best and most easily absorbable sources of vitamins A and D are in many of the foods that have been labeled “unhealthy” for the past few decades. These foods include whole eggs with the yolks and grass-fed butter.[2] Current studies have confirmed that these formerly unhealthy foods are actually pretty darn healthy for us.

So put a little pat of butter on your vegetables and let it nourish you on a deeper level.

3. A Strict Vegan Diet

I know many health-obsessed folks as well as well-meaning animal lovers that have adopted a vegan diet. That may be a pretty good idea because we are overeating meat and under-eating plants. But, too often I’ve witnessed people taking on a strict vegan diet and suffering from nutritional deficiencies that can lead to thyroid disease.

“One of many results of lack of protein is hypothyroidism because animal protein is required to make the thyroid hormone and to convert it to its active form in the liver.”[3]

My advice to the vegans that are suffering from thyroid disease is to continue eating plants because they are really good for you, and to supplement with naturally raised grass-fed animal proteins because they are good for you, too.

Your thyroid gland and the rest of your body will love you for it.

4. So Much Soy

Healthy folks in the know already understand that non-fermented soy foods in excess can be problematic for the thyroid and they can promote goiter. Those foods include soy milk, soy meats, soy nuts, soy chips, tofurkey, and other non-fermented soy products.[4]

Traditionally fermented soy, on the other hand, can be quite healthy for many people and includes miso, shoyu, tempeh, natto and tamari.

But, what people do NOT realize is that they may be eating non-fermented, non-traditional soy ingredients and they do not even know it! Soy can be disguised as isolated soy protein, textured vegetable protein, hydrolyzed vegetable protein, lecithin, bouillon, natural flavors, msg, Mono-diglyceride, and plant proteins.[5]

Soy is hidden within our food supply and we don’t even realize it. Those energy bars, natural snack bars, protein powders, and healthy breakfast cereals often contain highly processed soy ingredients that could be damaging your thyroid.

No matter how healthy food claims to be, read the label and check the ingredients.

5. Frequent Smoothies

I saved the best for last – smoothies! These are quick and easy and smooth and creamy, and every health fanatic is drinking them.

Many of those smoothies contain frozen fruit and fresh or frozen greens, plus some type of milky substance like almond milk, soy milk, coconut milk or rice milk. This can be a triple whammy for the thyroid!

First off, many of those smoothies contain raw greens like kale or raw green powders that contain the anti-nutrients that can inhibit iodine uptake.

Secondly, if that smoothie contains coconut milk, soy milk, rice milk or almond milk, they may also have carrageenan listed as an ingredient. Carrageenan has been linked with cancer, inflammation and digestive distress.[6]

Many thyroid conditions, especially autoimmune conditions like Hashimotos and Graves, can stem from poor gut health and digestive problems.[7]

Thirdly, humans are not designed to drink carbohydrates and proteins. Our food needs to be partially broken down by the process of chewing and by the chemical action of mixing it with salivary enzymes. If we don’t mix our food with saliva to start the process of digestion in the mouth, it can contribute to a whole host of tummy troubles (and blood sugar imbalances).

Please keep in mind that the information I shared doesn’t mean that you can never drink a green smoothie again, or you must forgo the raw veggie platter at the party, or that you can’t eat a low-fat or vegan inspired meal, it just means that if your thyroid is not functioning well, it’s time to make some shifts within the “healthy” diet you are already eating.

With knowledge comes power!

It’s possible to continue eating healthfully and really, truly feel healthy and vibrant at the same time.
