An underactive thyroid, or hypothyroidism, occurs when the thyroid gland stops producing an adequate amount of thyroid hormones. Symptoms of hypothyroidism may include fatigue, weight gain, forgetfulness, constipation and dry skin. Dietary changes and certain herbs may be helpful adjuncts to thyroid medication, but should not be taken exclusively to treat hypothyroidism. Always check with your doctor about taking herbs for medical conditions.
Foods to Eat
There is no specific diet that can treat an underactive thyroid, according to MayoClinic.com, but certain foods may reduce its symptoms. The University of Maryland Medical Center recommends eating antioxidant-rich foods like tomatoes, blueberries, bell peppers and squash. Foods high in iron and B-vitamins, such as fresh vegetables and whole grains, may also reduce symptoms of hypothyroidism.
Foods to Avoid
Excluding foods from your diet that may impede thyroid function may ease symptoms of an underactive thyroid. Potential culprits include broccoli, cabbage, cauliflower, spinach, peanuts, linseed and mustard greens. Soy, walnuts and cottonseed meal may hinder the absorption of thyroid hormone replacement therapy, notes MayoClinic.com.
Bladderwack
Bladderwack is a type of seaweed that contains iodine. It's been used to treat thyroid disorders such as goiter, an abnormally enlarged thyroid gland that can be caused by an iodine deficiency. Bladderwack may stimulate an underactive thyroid, according to the Clayton College of Natural Health. Ask your health care provider about using bladderwack for hypothyroidism.
Coleus
Coleus may promote proper thyroid function, according to the website American Chronicle. The recommended dosage for an underactive thyroid is about 75 mg two to three times daily. Consult with your doctor prior to taking coleus for hypothyroidism. Women who are pregnant or breastfeeding should not take coleus. Coleus may increase the risk of miscarriage.
Guggul
Taking 250 to 500 mg of guggul, also known as Commiphora mukul, is recommended for low thyroid support by the University of Maryland Medical Center. Animal research published in January 2005 in "Phytotherapy Research" found that guggul appears to improve hypothyroidism in mice. Check with your doctor about taking guggul for an underactive thyroid.
