Nutrition for a Healthy Thyroid

The thyroid gland produces 2 hormones that increase the activity of almost all body tissues. Many nutrients are involved in the process of making these hormones, which are made from the mineral iodine and the amino acid tyrosine. Some authorities say that up-to 40% of people have some degree of poor thyroid function, though most of these will not show up in blood tests. The causes are not well understood, but a link to nutrient deficiency and poor bowel health can often be found. There are many symptoms associated with low thyroid function especially fatigue, feeling cold, constipation, depression and coarse skin & hair. However these symptoms may have other causes.

Increase:

l Seaweeds, especially kelp, kombu and arame, are rich in the vital mineral iodine. A standard dose in cooking is 5-15g daily (dried weight). They may be used in many recipes and are especially good in soups and casseroles.

l Organic seeds and nuts. Buy in small quantities and keep in the fridge to prevent rancidity.

l Herbs and spices used in cooking e.g. thyme, oregano, coriander, garlic & turmeric.

l Whole foods and organic foods.

lDrink nettle and damiana tea.

Decrease:

l Stimulants such as tea and coffee.

l Sugar.

l Processed foods.

l Foods to which you may be allergic. Wheat and dairy products may be a problem (organic biolive yoghurt is usually ok).

l Cabbage family vegetables such as sprouts and turnip, along with mustard, contain a substance that competes with iodine.

Supplementation:

l Kelp

l A multinutrient complex that includes vitamins A, B2, B3, B6 & E, and the minerals zinc and copper.

l Vitamin C
