Change Your Diet, Transform Your Life

healthy-cup-fruits-raspberries.jpgA recent article written by Danielle Walker, author of the popular Paleo cookbook, Against All Grain, tells an inspiring story of how she completely turned around her health and her life through dietary changes. Walker suffered from a debilitating digestive illness called Ulcerative Colitis and found herself in constant pain and unable to care for her family. After working with a naturopathic doctor and eliminating grains, dairy, refined sugars, and other foods that she was sensitive to, she was able to get off her medications and prevent surgeries and further hospitalizations.

paleo-healthy-dietThe Paleo diet has gotten a lot of attention in the popular press lately and it can be easy to dismiss as simply one more fad diet. The basic premise of Paleo is to eat unprocessed whole foods and to avoid grains, dairy, and other foods that tend to promote inflammation. Inflammation in the body can cause chronic pain and has been shown to trigger a myriad of chronic diseases. I have personally seen the benefits of the Paleo diet in people with autoimmune diseases, diabetes, and PCOS (Polycystic Ovarian Syndrome). By replacing inflammatory foods with healthy, whole, unprocessed foods like vegetables, lean protein, and good fats, you can build a strong foundation of health and wellness.

Dietary changes unfortunately aren’t usually a quick fix and it can take months of sticking to a new plan before the true results become obvious. However, with patience and motivation, the benefits of diet are often profound and long lasting.

I often recommend a basic whole-foods-based diet like the Whole30, which cuts out sugar, diary, alcohol, grains, legumes, and processed foods in favor of vegetables, fruits, eggs, meat, nuts, and seeds. Although it is billed as a 30 day detox and diet plan, many people find that they feel so well eating this way that they incorporate these changes into their long-term eating choices.

Some people with autoimmune diseases find that they feel best when they also avoid tree nuts and vegetables in the nightshade family (i.e. peppers, eggplant, potatoes, and tomatoes). Although these foods do not cause inflammation in everyone, some people find that they don’t tolerate them well, especially when their disease is in a flare. This diet is called the autoimmune paleo protocol, and although it can be challenging to stick to, many people experience a significant decrease in pain and other symptoms when they follow it.

There are many variations on healthy, whole-foods-based diets. If you are interested in finding an individualized diet plan to help you feel your best, consider working with a naturopathic doctor or a nutritionist who is trained in whole-foods nutrition. Practitioners who are trained in nutrition can help make sure that you are eating a balanced diet with sufficient nutrients.

Brazil Nuts and Thyroid Health: Selenium as a Treatment for Autoimmune Thyroiditis (Hashimoto’s)

Do you have hypothyroidism? If so, you are not alone. Depending on the study you look at, hypothyroidism effects between 3% and 10% of the U.S. population. Hypothyroidism is a deficiency of thyroid hormones and is usually caused by under functioning of the thyroid gland. The disorder can cause symptoms of fatigue, weight gain, brain fog, constipation, cold intolerance, dry skin and hair, hair loss, and irregular menstrual cycles.

ThyroidWhat is the Thyroid?

The thyroid is a small gland located in the front of neck and is a power house for the body. The thyroid gland produces our thyroid hormones, namely triiodothyronine (T3) and thyroxine (T4). T3 and T4 are synthesized from tyrosine, iodine, and various proteins. T3 is the most biologically active form of the hormone and receptors for T3 are located on cells all over the body. Thyroid hormones regulate the body’s metabolic functions, telling our cells how much energy to use, as well as controlling other hormonal systems.

The Thyroid and the HPA axis

Thyroid function is coordinated by two areas in the brain, the anterior pituitary and the hypothalamus. The pituitary gland and hypothalamus are two components of the hypothalamic–pituitary–adrenal (i.e. HPA) axis, which also includes the adrenal glands. The HPA axis is a complex relationship of hormones that control many functions in our bodies, including metabolism and reproductive functions.

The hypothalumus is responsible for producing thyrotropin-releasing hormone (TRH), which then stimulates the pituitary gland to release thyroid-stimulating hormone (TSH). TSH stimulates the thyroid gland to produce thyroid hormones, T3 and T4. Normally, this process is a well-oiled machine with many efficient feedback loops, but there is the potential at any point for dysfunction to occur.

Causes of Hypothyroidism and Low Thyroid Function

Hypothyroidism is a medical term for low thyroid function. Hypothyroidism occurs when the thyroid gland does not produce enough T3 and T4 hormones. Most people with hypothyroidism will have elevated levels of TSH because the pituiatry gland will try to trigger the thyroid gland to function normally.

Hypothyroidism can have many causes. In developing countries, the most common cause of hypothyroidism is iodine deficiency. Iodine is a naturally occurring mineral found in many foods including seaweeds, milk and dairy products, fish and seafood, and eggs. The Recommended Daily Allowance (RDA) for iodine is 150 mcg for most adults, except for pregnant and breastfeeding women who should consume 200 mcg daily. In the United States and many other countries iodine intake is generally adequate because this nutrient is added to table salt. Therefore, in the U.S. the most common cause of a low functioning thyroid gland is Autoimmune Thyroiditis, also called Hashimoto’s Thyroiditis.

Hashimoto’s and Autoimmune Thyroiditis

Autoimmune diseases occur when the body creates autoantibodies and starts to attack its own tissues, organs, or glands. In Autoimmune Thyroiditis, antibodies may be produced to Thyroid Peroxidase (called Anti-TPO anitbodies) and/or Thyroglobulin (Anti-TG antibodies). Thyroglobulin is the primary protein component of thyroid hormones. Thyroid Peroxidase is an enzyme that helps iodine molecules attach to thyroglobulin in order to make the thyroid hormones T4 and T3. When the body cannot make enough thyroglobulin or thyroid peroxidase, hypothyroidism often occurs.

Unfortunately, we don’t know for sure what causes autoimmune diseases. There is often a genetic component, with some disorders being more common in families. There may also be environmental triggers such as toxic exposures, reactions to medications, or periods of prolonged stress. For most people, there is likely a combination of triggers along with a genetic predisposition that eventually tips the scales in favor of autoimmune reactions.

Treatments for Hypothyroidism

The typical treatment for Hypothyroidism is replacement of one or more of the thyroid hormones. Common medications include Levoythyroxine (containing only T4), USP Glandular Thyroid (containing both T3 and T4), or Liothyronine (only T3).

Selenium as a Treatment for Autoimmune Thyroiditis

Less is known about how to treat the autoimmune process that is taking place in Hashimoto’s, but a promising study published in the Society for Endocrinology shows that moderate supplementation with the nutrient selenium may decrease thyroid antibodies in Autoimmune Thyroiditis. The study showed the most benefit from taking daily selenium doses of 200mcg, which decreased levels of both Anti-TPO and Anti-TG antibodies.

Natural Sources of Selenium

Selenium is naturally found in many foods, although the levels generally reflect the amount of the mineral found in the soil where the food is grown. The best dietary source of selenium is Brazil nuts and eating 3 nuts per day gets you to approximately 200 mcg of selenium. Other sources of selenium include tuna, sardines, ham, shrimp and halibut, but the levels in these foods is much lower. For those with Autoimmune Thyroiditis, selenium may be an important supportive treatment to use in conjunction with thyroid hormone replacement therapies.
