Hypothyroidism is a condition in which the thyroid gland does not produce adequate amounts of the thyroid hormone. This condition can be caused by medication, a congenital defect or by intentional destruction of the thyroid gland. Without enough thyroid hormone, the body develops symptoms of hypothyroidism including depression, weight gain and fatigue. Synthetic thyroid hormone medication is usually given to individuals who have hypothyroidism and must be taken for the rest of the individual's life. Eating habits, too, can have an effect on the health of an individual with hypothyroidism.
Step 1
Limit the amount of fiber you eat. Individuals who have hypothyroidism and who are taking a hormone replacement should watch their fiber intake. This is because too much fiber can impair the absorption of the hormone, causing symptoms to continue or worsen. Ask your doctor or dietitian how much fiber you should be consuming daily.
Step 2
Eat foods that are rich in B vitamins and iron, such as lean red meat and whole grain products. Individuals with hypothyroidism also may experience anemia, which is caused by the body's inability to produce enough red blood cells. Many symptoms of hypothyroidism, such as fatigue and sensitivity to cold, can also be caused by anemia. Eating foods rich in iron and vitamin B can help restore the red blood cells that provide oxygen-rich blood to the body.
Step 3
Avoid foods that are known to impair the functioning of the thyroid. These foods include members of the cruciferous family, such as cabbage and cauliflower. In addition, avoid eating turnips, peanuts, pine nuts and mustard greens. Focus instead on eating fresh fruits and vegetables not known to interfere with thyroid function. Be sure to include berries, squash, bell peppers and tomatoes in your diet, because these foods are rich in antioxidants.
Step 4
Avoid products that contain soy. Although soy products are generally recommended as healthy, they can impair the absorption of thyroid replacement hormone. Be sure to read nutritional labels to check for soy-based ingredients, such as soybean oil and soybean flour. Rotate the foods you eat to ensure that any product that might contain a hidden source of soy won't perpetuate the impairment of absorption.
Step 5
Maintain your caloric intake at or below your recommended daily total, based on your height, weight, age, gender and level of activity. Decreased thyroid function causes a slowing of the metabolism which leads to the weight gain commonly experienced with hypothyroidism. Staying near your recommended caloric requirement can help you attain and maintain a healthy weight, preventing many health problems associated with obesity.
