What Iodine Does? Iodine, a Non-Metallic Trace element, is mostly found in our Thyroid Glands (Along with Blood, Muscles & Ovaries). Required for-Does Following:
- Production (Synthesis) of Thyroid Hormones (T3 & T4) (Necessary for Normal Body Growth, Optimally Functional Nervous System & Body Metabolism),
- T3, a Physiologically Active Thyroid Hormone, binds to Specific Receptors in Cell’s Nuclei & Regulates Gene Expression, and hence plays an important role in proper functioning of Reproductory organs of The Body.
Also, Iodine is frequently used for Dis-infecting Wound,
Reasons for Shortage of Iodine (Classic Symptom is Enlargement of Thyroid Gland, Though Excess Iodine can also cause Goitre): Un-Balanced Diet, Side Effects of Medicinal Drugs, Smoking (Goitrogens), Excess soya-bean Intake (Goitrogens)…
Iodine Deficiency may lead to: More Prevalent in Females than in Males.
- Scanty Production of Thyroid Hormones (Hypothyroidism-Fatigue-Weight Gain-Dry Skin-Sensitivity to Heat),
- Goitre (Thyroid Gland Enlargement) (Actually, connected to Hypothyroidism, Thyroid Enlargement is simply in correspondence to Low Iodine such as to maximise the Uptake of Available Iodine – Though Excess Goitre would Obstruct Trachea-Oesophagus & consequently damage Laryngeal Nerves),
- Oral Inflammation,
- Fibrocystic Breast,
- Cretinism (Severe Physical-Mental Retardation),
- Iodine Deficiency during Pregnancy may lead to Foetal Hypothyroidism-Miscarriage-Pre-term Birth-Neurological Impairment in offspring,
- Chronic Brain Damage…
Rich Source of Iodine: Total Human Body iodine Content is around 15-20 mg, 70-80% of that is concentrated in the thyroid Glands, and finally 80 Micro-Grams of that utilised by our Body on Daily Basis to Synthesis Thyroid Hormones.
High percentage of our Dietary Intake of Iodine (90%+) is excreted from our system in 24-48 hours
Plant Sources: Rock Salt, Garlic, Sesame Seeds, Spinach, Turnip Greens, Lima Beans, Tomatoes, Carrot, Kelp, Baked Potato (With Peel), A Seaweed (A Very High Source), Hemp Seeds…
Fruit Sources: Pineapple, Cranberries, Strawberries, Apples, Peas, Banana…
Animal Sources: A-2 Milk (High Source), Seafood, Shellfish, Kelp, Deep-Water Fish, Eggs, Cheese…
Iodine Deficiency coupled by deficiency of Selenium, Iron & Vitamin-A, all at the same time have been found to aggravate the Iodine Deficiency Disorders, and hence optimal intake of the Minerals mentioned, along with Iodine is very important.
Daily Recommended Values:
Adults: 135 – 300 mcg/Day (And this would be the figure that should be reflected in the Urinary Iodine Concentration, as I said more than 90% Iodine ingested is excreted in 24-48 hours!). Upper Tolerable Limit has been put at 1000 Micro-Grams or a Gram/Day – But for God’s sake don’t even think of reaching that level on regular basis!!!
- I131 is radioactive and its accumulation in thyroid glands is Carcinogenic (Thyroid Cancer),
- Excess Iodine results in Hyperthyroidism (Multi-Nodular Goitre).
