No Goitrogenous Foods In Your Smoothie!
Goitrogens are substances that interfere with iodine uptake by the thyroid gland, and the production and function of the thyroid. This is where we get the word goiter from. It is possible to get a toxic goiter from too many raw goitrogenic vegetables. All cruciferous vegetables from the cabbage family contain goitrogens. This includes kale, cabbage, cauliflower, bok choy, rutabaga, kohlrabi, mustard greens, brussels sprouts, broccoli, and turnips. Legumes also contain goitrogens – such as soybeans, lentils, peas, bean sprouts, etc. This does not mean you can never eat these vegetables. The good news is that most goitrogens are destroyed by heat, especially with cruciferous vegetables. You only have to cook them lightly to neutralize the goitrogen toxins in them. But, if you are juicing kale or adding raw kale to your smoothies, you are doing your thyroid a huge disservice. This will promote hyperthyroidism by depressing the thyroid. All of these cruciferous vegetables are better off cooked. if you do not have a thyroid problem, you could eat themraw, once in a while.
The worst goitrogen is soy. The anti-thyroid substances in soy are not destroyed with heat. Soy is everywhere, in packaged foods especially. Many people think soy is a health food and even drink soy milk. Lots of gluten-free foods contain soy flour. Even soy oil is bad for the thyroid, because it interferes with your thyroid hormones. The only soy I would touch is fermented soy, on occasion. Usually, I even sub coconut aminos for soy sauce. Fermenting soy does reduce, but not eliminate, goitrogens.
Other goitrogenic foods are pine nuts, flax seeds, peanuts, mustard, spinach, arugula, maca, strawberries, peaches, pears, sweet potatoes, lima beans, watercress, millet, bamboo shoots, and canola. You can still eat these things in moderation if you have a thyroid problem… but cook all vegetables if you can.
Even though I am a former raw food vegan (a long time ago, obviously it didn’t work out for me), I don’t recommend eating your vegetables raw. Though most people have heard the false information that raw vegetables break down easily in the gut, and meat rots in your gut, it is simply not true. If you know anyone with a colostemy or ostemy bag, you already know that meat breaks down very quickly to a liquid state in about 20-30 minutes) and vegetables never break down all the way.. you’ll see them (ahem) again when they exit your body.. you’ll see them if you have a colostemy or ostemy bag. Here’s a fascinating article of a man with an ostemy bag, who tried to even swallow large pieces of meat to see if they wouldn’t break down, and couldn’t find any meat that didn’t turn to liquid very quickly.

The raw food craze has many people believing that raw is the only way to go; the naturally occurring enzymes in raw food help your body digest the raw foods that you eat–and they are right. However, the issue with raw vegetables is that the vitamins and minerals are embedded in a complex mass of fiber called cellulose, a carbohydrate that is difficult for the human body to digest, possibly resulting in gas, bloating and nausea. In addition, many of the valuable nutrients in raw vegetables are not being absorbed by the body.
If food is not digested properly, the carbohydrates, protein, fat, vitamins and minerals are not being absorbed. Digestion and absorption must happen in order for your body to take full advantage of any food, especially vegetables. If eating raw vegetables is burdening your digestive system, consider cooking certain vegetables or using digestive aids.
Cooking carrots, spinach, mushrooms, asparagus, cabbage, peppers and many other vegetables also supplies more antioxidants, such as carotenoids and ferulic acid, to the body than they do when raw, says Rui Hai Liu, an associate professor of food science at Cornell University. On the flip side, cooking can destroy the high levels of vitamin C found in certain vegetables, as well as naturally occurring enzymes that assist digestion.
Of course, I don’t agree with the part of the article which suggests that fiber is good for you, I feel best on my fiber-free diet! As do the others that follow a very low carb lifestyle. Thanks for reading, I hope this article brings you to some great research to help and heal your body!
