DIETARY AND LIFESTYLE CHANGES FOR AN UNDERACTIVE THYROID
If a person does present with reduced thyroid function the only way out seen by many is for a lifelong prescription of thyroxin hormone. However, nutritional support containing synergistic blends of herbs and nutrients can be successfully utilised in a regime and prevent the patient from descending into a downward spiral of ill health.

Dietary Changes
Try to increase your consumption of fruits, vegetables and lean proteins. All of these help increase the metabolic rate and supply vitamins and minerals necessary for the glandular system. Avoid regular or habitual consumption of fast foods, processed foods, and junk foods. These are high in calories, low in nutrition, and they will slow down the metabolism. Simple carbohydrates, such as sugar and refined flour, will also slow the metabolism and should be avoided.
Selenium-rich Foods: selenium deficiency is a major factor in low thyroid function, and you should regularly include selenium-rich foods in your diet. The thyroid produces several hormones, and must produce them in a somewhat balanced ratio. Without selenium, this balancing process is hindered. Good sources of selenium in your diet include: wheat germ, tuna, herring and other seafood and shellfish, kidney, eggs, sunflower and sesame seeds, cashews, mushrooms, garlic, and onions.
Soy products like tofu and soya milk can help to mildly stimulate thyroid function. Certain other foods have a tendency to lower thyroid function and need to be avoided by those with underactive thyroids: turnips, mustard greens, broccoli, cabbage, rutabaga, brussels sprouts, bok choy, cress, cauliflower, kale, and kohlrabi.
