Hypothyroidism is a disorder of the thyroid gland that results in an underproduction of thyroid hormones. Common symptoms include fatigue, sluggishness, dull or dry skin and hair, constipation, lack of motivation, slow heart rate, inability to tolerate cold, painful menstruation, muscle weakness, hair loss, migraines, yellow-orange colored palms, depression, swollen eyes and unexplained weight gain. These symptoms can mimic many other disorders, and it is important that you see a health-care practitioner for a proper diagnosis.
Avoid Iodine Depleting Pesticides and Soy
According to Danielle Perrault in her book "Nutritional Symptomatology," an underactive thyroid has been strongly linked to an iodine deficiency because iodine is integral to the formation of thyroid hormones. The Canadian School of Natural Nutrition, or CSNN, says that you should eat organic food because some pesticides are known to interfere with iodine absorption in the body. CSNN also recommends limiting or avoiding your consumption of soy because it is also suspected to decrease iodine absorption.
Avoid Chlorine and Fluoride
According to Phyllis Balch in her book "Prescription for Nutritional Healing," you should avoid chlorine found in tap water and fluoride found in tap water and toothpaste. She says that chlorine and fluoride interfere with the thyroid's ability to produce iodine containing hormones, which can ultimately lead to hypothyroidism. You can ensure that your water is chlorine and fluoride-free by choosing steam-distilled water or spring water bottled at the source and using a natural toothpaste that says fluoride-free on the label.
Take Supplements or Eat Iodine Rich Foods
Food that will provide you with a rich source of iodine include iodized sea salt, seafood, kelp, seaweed and other sea vegetables. An iodine supplement that provides between 150mcg and 600mcg can also be taken under the supervision of your health care practitioner. Selenium seems to help enhance iodine absorption, and Perrault recommends consuming high-selenium foods such as Brazil nuts, wheat germ, kidney, liver, tuna, shellfish, sunflower seeds and lentils. Alternately, take a 200 to 400mcg selenium supplement daily.
Avoid Raw Brassica Vegetables
Finally, if you have hypothyroidism, Perrault recommends that you avoid eating any raw brassica vegetables, including cauliflower, broccoli, cabbage, turnips, Brussels sprouts, rutabagas, bok choy, millet and cassava. She says that these foods are "goitrogenic" -- meaning they suppress thyroid function when eaten raw. Eating these foods cooked and in moderation, however, is OK because cooking reduces their goitrogenic properties.
