Who are thyroid patients?

Thyroid patients are individuals with a medical condition that affects their thyroid gland. The thyroid gland is a small butterfly-shaped gland located in the neck that produces hormones that regulate bodily functions like metabolism, heart rate, and body temperature. There are several different types of thyroid conditions, including:

-hypothyroidism: a condition in which the thyroid gland produces too little thyroid hormone.

-hyperthyroidism: a condition in which the thyroid gland produces too much thyroid hormone.

-thyroiditis: inflammation of the thyroid gland, which can cause temporary hypothyroidism or hyperthyroidism.

-thyroid nodules: growths on the thyroid gland that may be benign or cancerous.

-thyroid cancer: a type of cancer that develops in the thyroid gland.

Thyroid patients may require medical treatment, such as thyroid hormone replacement therapy, surgery, or radioactive iodine therapy, depending on their specific condition and symptoms.

How much protein do thyroid patients need?

The protein requirements for thyroid patients are generally the same as for individuals without thyroid conditions. That said, thyroid hormones play a vital role in regulating metabolism, including the metabolism of protein. In individuals with an under-active thyroid (hypothyroidism), the metabolism may slow down, making it harder for the body to process protein. In such cases, the recommended protein intake may need to be slightly higher than for individuals without thyroid disorders to maintain muscle mass and support other body functions. On the other hand, individuals with an overactive thyroid (hyperthyroidism) may require more protein to support the increased metabolic rate associated with their condition.

Thyroid patients should aim to get as much protein as they can from dietary protein sources like eggs, fish, legumes, nuts, and meat, but this is often easier said than done. People with dietary restrictions, reduced appetite, and busy schedules, for example, are not always able to meet their protein needs this way, which is where protein supplements can help. Adding a protein shake or powder to your diet is a great way to ensure that you are getting enough protein, and managing your symptoms. What constitutes enough protein is different from everyone, but you should be eating at least 0.36 grams per pound of body weight per day. This means that a 150 pound person should be eating at least 54 grams of protein. Use our Daily Protein Intake Calculator to figure out how much protein you need.

Can too much protein cause thyroid problems?

There is currently no evidence to suggest that consuming too much protein can directly cause thyroid problems. However, certain types of high protein diets may indirectly affect thyroid function in some people. For example, diets that are extremely low in carbohydrates and high in protein may cause the body to produce less thyroid hormone. This is because carbohydrates are needed for the body to convert the inactive form of thyroid hormone (T4) to the active form (T3). Without enough carbohydrates, the body may not be able to make enough T3, which can lead to symptoms of hypothyroidism. Moreover, diets that are very high in protein may also increase the body’s need for iodine,  a mineral essential for thyroid function. If a person is not getting enough iodine in their diet, consuming excessive amounts of protein may further increase their risk of developing iodine deficiency and subsequent thyroid problems.

not all protein powders are created equal

What is the best protein powder for thyroid patients?

Research has found that certain protein supplements can affect your hormone levels. Whey protein supplements, for example, can interfere with thyroxine absorption. Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. The exact mechanism by which whey protein interferes with thyroxine absorption is unclear. That said, research has shown that they can interfere with thyroid hormone transporters in the intestine. It is also entirely possible that added ingredients, not the protein itself are the problem. For instance, researchers think that soy lecithin, a common additive used in whey protein supplements, may also contribute to the impaired thyroxine absorption. The point here is that thyroid patients should be cautious when using a) diary-based protein supplements and b) supplements with food additives.

Increasing scientific evidence suggests that, over time, food additives can disrupt the endocrine system, the system of glands that make hormones. Given that most protein shakes and powders contain additives (emulsifiers, stabilizers, thickeners, sweeteners, flavors, preservatives, etc.), and that many people drink protein shakes every day, this is reason for concern. One of the main reasons why food additives affect your hormones is that they disrupt the hormone-gut microbiome axis, the two-way biochemical signaling pathway between the microorganisms living in your digestive tract and your endocrine system. In other words, the composition of your gut microbiome has a profound impact on your hormonal environment, which means that an imbalance in your gut microbiome may cause a hormonal imbalance. Food additives, it turns out, are terrible for your gut, and therefore terrible for your endocrine system. This is especially true for people with hormone-related diseases.

For healthy individuals, the type and amount of protein that you consume should not disrupt your hormones. People with a hormone imbalance may want to consider avoiding dairy and soy-based ingredients, as both have been shown to impact hormone levels more than other dietary protein sources, but even dairy and soy, if consumed in moderation, should not cause problems. Food additives, on the other hand, are a different story. Accumulating evidence suggests that food additives, and therefore most protein supplements, may cause a hormonal imbalance over time. For this reason, you should pick the protein supplement with the fewest additives possible, or with no additives at all.

There are two types of protein supplements: ready-to-drink (store-bought) protein shakes, and protein shakes made with protein powder. In order to make protein shakes for hypothyroidism with protein powder, you have to mix the powder with milk or water. This requires a blender or a shaker bottle, and a little extra time and effort. Some people therefore prefer to buy ready-to-drink protein shakes, but if they knew what they were drinking, they would probably vomit. Ready-to-drink protein shakes are full of additives, which is why I recommend that you make your own protein shakes for hypothyroidism with protein powder. That said, not all protein powders are created equal, and many contain the same additives found in ready-to-drink protein shakes!

Why drink wholesome

drink wholesome is additive-free.

One of the reasons why we make the best protein powder for thyroid patients is that we do not use food additives. As you just learned, food additives can disrupt regulatory pathways in your gut, which, in turn, can disrupt your endocrine system. One additive to avoid in particular is artificial sweeteners. Artificial sweeteners are among the most harmful food additives in the long term as they alter the composition of your gut microbiota, causing permanent damage to the gut microbiome.

Here is a list of the most common food additives in protein powder:

acacia gum, acesulfame potassium, artificial flavors, aspartame, carrageenan, cellulose gum, dextrin, dextrose, erythritol, gellan gum, guar gum, gum arabic, inulin, locust bean gum, “natural” flavors, maltodextrin, rice syrup solids, soy lecithin, silica, sucralose, sunflower lecithin, xanthan gum, xylitol

When it comes to identifying food additives, go with your gut. 😉 As a rule of thumb, they are the ingredients that you cannot pronounce. Food additives are not the only thing to look out for when buying protein powder, however. There are several other ingredients that can disrupt your gut microbiome and affect your endocrine system.

the alternative:

Protein Matrix Comprised of (Whey Protein Concentrate,  Whey Protein Isolate, Calcium Caseinate, Micellar Casein, Milk Protein Isolate, Egg Albumen, Glutamine Peptides), Polydextrose, Sunflower Creamer (Sunflower Oil, Corn Syrup Solids,  Sodium Caseinate, Mono- and Diglycerides, Dipotassium Phosphate, Tricalcium Phosphate, Soy Lecithin, Tocopherols), Natural and Artificial Flavor, MCT Powder (Medium Chain Triglycerides, Nonfat Dry Milk, Disodium Phosphate, Silicon Dioxide), Lecithin, Cellulose Gum, Salt, Yellow 5, Sucralose, Acesulfame Potassium, Papain, Bromelain.

*This is the actual ingredient list of one of the best-selling protein powders in the United States.

drink wholesome is dairy-free.

Another reason why we make the best protein powder for thyroid patients is that we do not use dairy-based proteins. Many protein powders are made with whey and casein, which are byproducts of cheese and yogurt production, and known to cause digestive issues, especially for people with lactose intolerance and irritable bowel syndrome (IBS). Over one in three Americans are lactose intolerant, and the prevalence of IBS is somewhere between 10 and 15 percent in the United States. It follows that you may be lactose intolerant or have IBS and not even know it.

drink wholesome is made with real foods.

A final reason why we make the best protein powder for thyroid patients is that we do not use protein isolates. Most protein powders, on the contrary, are made with protein concentrates and/or isolates, foods stripped of everything but the protein. They are listed on the ingredient list as “collagen protein,” “pea protein, and” “whey protein” as opposed to “collagen,” “peas,” and “whey.” I will not go into the details, but protein concentrates and isolates undergo heavy mechanical and chemical processing before becoming protein powder. Sometimes, manufacturers use chemical solvents like hexane to isolate (separate) the protein from the food. This means that what you end up putting into your body looks nothing like real food. If you think about it, your gut was designed to digest naturally occurring foods, not laboratory formulated imitations, so if you feed it anything but real food, it might get upset.

Instead of protein concentrates or isolates, we make the best protein powder for thyroid patients with egg whites and almonds. Egg whites are simply pasteurized and dried before becoming protein powder. Almonds are just roasted, pressed, and ground. Minimally-processed ingredients like these are an easy to digest, gut-friendly alternative to protein concentrates and isolates. Unless you have a sensitivity or allergy to eggs, egg white protein is the best protein for your gut. Egg whites are low in fiber, low-FODMAP, naturally alkaline, and have the highest protein digestibility-corrected amino acid score (PDCAAS) of any whole food. Our customers have experienced fewer digestive issues with egg white protein than with any other type of protein. If you cannot eat eggs, try our almond protein powder. Unlike protein concentrates or isolates, almonds contain lots of healthy fats, fiber, and other nutrients like calcium and vitamin E. We prefer almonds to other minimally-processed plant protein sources because they are more gut-friendly. Research suggests that almonds possess prebiotic properties and can improve the diversity and composition of the gut microbiome.
