The function of the Thyroid Gland
The function of the thyroid gland is to take iodine, found in many foods, and convert it into thyroid hormones: thyroxine (T4) and triiodothyronine (T3). Thyroid cells are the only cells in the body which can absorb iodine. These cells combine iodine and the amino acid tyrosine to make T3 and T4. T3 and T4 are then released into the bloodstream and are transported throughout the body, where they control metabolic rate, metabolism and many other vital functions such as cardiac output, heart rate and respiratory rate. Indeed every cell in the body depends upon thyroid hormones for regulation of their metabolism.
The normal thyroid gland produces about 80% T4 and about 20% T3. However, T3 possesses about four times the hormone "strength" of T4 - T3 is the “metabolically active” thyroid hormone. The minerals zinc, copper, manganese and selenium are also needed for the conversion of T4 to T3.
Those with a low basal metabolic rate might be short of T4 or short of the nutrients that convert T4 to T3. If tests show a high level of TSH (thyroid stimulating hormone) and high T4 but patients have a low basal metabolic rate, then it is most likely that they are not converting sufficient T4 to T3 and appropriate nutritional intervention will be helpful.
Iodine & the Thyroid Gland
Iodine is one of the micronutrients known to be short in the diets of many. It naturally occurs in sea produce and salt. Those on low salt diets and those consuming less than 3 portions of fish a week can easily be short of iodine intake. Moreover, those people living in areas where the water is fluoridated easily become iodine deficient, as fluoride inhibits uptake of iodine to the thyroid gland.
L- Tyrosine & the Thyroid Gland
Tyrosine, which can be synthesised in the body from phenylalanine, is found in many high protein food products such as soy products, chicken, turkey, fish, peanuts, almonds, avocados, milk, cheese, yogurt, cottage cheese, lima beans, pumpkin seeds and sesame seeds.
It is beneficial to have l-tyrosine and iodine ingested together in a form that can be immediately usable by the thyroid gland to promote production of thyroid hormones.
