Guest guest Posted May 26, 2006 Report Share Posted May 26, 2006 Iodine in Sea vegetables Useful for Mercury Detox & Thyroid Function Sea vegetables - thyroid JoAnn Guest Jun 12, 2004 13:21 PDT The thyroid gland, situated in the front of the neck, is responsible for producing hormones which control our metabolism. Toxins from the environs may alter thyroid function. Eduardo Gaitan from Univ Mississipi found that drinking water contaminated with petrochemicals results in " blocked activity " of thyroid hormones. ( Ref Jounal of Clinical Endocrinology & Metabolism 1983 Vol. 56) Polychlorinated biphenyls (PCB's) can alter thyroxine levels and result in symptoms of thyroid disorders (Science, vol.267) It is now understood that the environment, diet and nutrition influence thyroid function in a number of ways and may relate to thyroid disorders of non specific origin (Annual Review of Nutrition -1995 Vol 15) The good news is that correcting the underlying thyroid deficiency can have dramatic effects on energy, mood, and cognitive function in the over-60 population. Thyrotoxic patients should avoid any stimulants such as caffeine,chocolate, coffee,amphetamines and nicotine in order to normalize thyroid function. --- Sea vegetables are really not a vegetable but large marine algae that grow in the coastal waters of many countries. They include thousands of species from microscopic plants called phytoplankton to huge floating/anchored plants commonly seen washed up on shore. Various kinds of seaweed are eaten by ethnic cultures because they are full of vitamins and iodine. Asian cultures use seaweed like green beans and carrots are used in the United States. One of seaweed's most prominent health benefits is its ability to remove radioactive strontium and other heavy metals from our bodies. Whole brown seaweeds (not granulated) such as kelp contain alginic acid which binds with the toxins in the intestines rendering them indigestible and carries them out of the system. Oriental herbalists have been exploring the medicinal powers of sea vegetables for centuries. They have long recognised their potential to enhance general well- being and in particular the health of thenervous system. But most recent interest has centred on the ability of the plants to cleanse the body of toxins. According to research from Dr. Tanaka at McGill University in Canada, the alginic acid present in sea vegetables binds with " heavy metal pollutants " in our intestines - such as lead and mercury - preventing them from being absorbed. Sea vegetables are virtually fat-free, low calorie and one of the richest sources of minerals in the vegetable kingdom as they have ready access to the abundance of minerals found in the ocean. Nourishment is acquired across the sea vegeable's entire surface through the gentle wave action of underwater currents. Sea water & human blood contain many of the same minerals in very similar concentrations. Sea vegetables contain high amounts of calcium and phosphorous and are extremely high in magnesium, iron, iodine and sodium. For example, 1/4 cup of cooked hijiki contains over half the calcium found in a cup of milk and more iron than in an egg, important concerns for vegans, those who refrain from eating any animal-based products. They also contain vitamins A, B1, C and E, as well as protein and carbohydrates. Protection against tumors, radiation and environmental pollutants Excerpts from the book: " Fighting Radiation with Foods, Herbs and Vitamins: Documented Natural Remedies That Boost Your Immunity and Detoxify " " The chemical pollution in air, soil and water is particularliy serious, since the pollutants find their way into the food chain and their absorption into the body can be hazardous ... Our investigation has shown that alginate can bind radioactive strontium .. binds with other metal pollutants such as excess barium, cadmium and zinc. " " There is no family of foods more protective against radiation and environmental pollutants than sea vegetables ... sea vegetables can prevent assimilation of different radionuclitides, heavy metals such as cadmium, and other environmental toxins. " They have a delicious mellow `sea' flavour, which varies from mild to barely perceptible according to the variety. Agar (Agar Flakes) Arame Dulse Hijiki Kombu Nori Strips Sea Salad (Dulse, Sea Lettuce, Nori - Breton) Wakame Governments world-wide are now stockpiling a supplement that protects the thyroid from radiation fallout (radioiodine). Amongst them are Japan, Canada, Britain, France, Germany, Poland, Switzerland, Denmark, Norway, Austria, Sweden, etc., but not the U.S. Learn how to protect your thyroid gland. In 1974 a report was published by I. Yamamoto et. al. in the Japanese Journal of Experimental Medicine, (44: 543-46). These scientists reported that several varieties of Kombu Mojaban (common sea vegetables eaten in Asia and traditionally used as a decoction for cancer in Chinese herbal medicine) were effective in the treatment of tumors in laboratory experiments. " In three of four samples tested, inhibition rates in mice with implanted sarcomas ranged from 89-95%. " " The tumor underwent complete regression in half of the mice in each treated group. " Similar experiments on mice with leukemia have also shown promising results. " In parts of the Far East they have never gone out of fashion, eaten as much today as they ever were. Now, they are attracting attention here in the West, as we begin to appreciate a food that delivers both tasty, tangy flavour and unparalleled nutritional benefits It's mainly about minerals. " Sea vegetables contain more minerals than any other kind of food, " says Professor Arasaki of Tokyo University, who has spent a lifetime studying them. Because sea vegetables are virtually fat-free and low in calories, you can eat generous helpings without piling on unwanted pounds. They also offer a plentiful supply of fibre, cleansing the intestines as they pass through the body. In our era of processed foods and iodine-poor soils, sea greens and sea foods stand alone as potent sources of natural, " balanced " iodine. www.edenfoods.com --- Iodine is essential to life; the thyroid gland cannot make thyrozin, the enzyme that " regulates " metabolism, without it. Iodine is an important element of alertness and rapid brain activity, and a prime deterrent to arterial plaque. Thyroid hormones are made from iodine and the amino acid tyrosine. Thyroglobulin, the mixture of tyrosine and iodine stored in the thyroid gland, is transformed into " hormones " that regulate our metabolism, protein, carbohydrate and carotene use, and cholesterol (sea greens help lower cholesterol drastically). The amount of thyroid hormone released into the bloodstream determines the body's basic energy level and along with the adrenal glands, the rate that sex hormones are made. Sea plants nourish an underactive thyroid and normalize adrenal functions. --- Goiter, a thyroid disorder, develops when the pituitary gland stimulates the thyroid to make more hormones but the thyroid can't do it because of an iodine deficiency. It enlarges in the attempt and goiter develops. The rate of goiter in the U.S. is still relatively high - 6% of the population in some areas. It's a strange situation, because few people in the U. S. are iodine deficient (the average American intake of iodine is estimated at over 600 micrograms daily from iodized salt). Since the recommended adult allowance for iodine is quite small, 150 micrograms, experts believe that at least some of the high rates of goiter are really connected to too much refined sugar, alcohol,bad fats such as hydrogenated vegetable oils and caffeine, or to eating a lot of goitrogen foods, which " block " iodine 'absorption'. Cooking 'neutralizes' the thyroid-blocking components in some foods, especially cruciferous vegetables (cabbage, kale, Brussels sprouts, broccoli, peanuts and cauliflower) which contain natural goitrogens, chemicals that cause the thyroid gland to enlarge by interfering with thyroid hormone synthesis. Cooking has been reported to inactivate this effect in cauliflower and Brussels sprouts. Cassava, a starchy root that is the 'source of tapioca', can also have this same effect. Other " goitrogens " include corn and corn derivatives (HFCS), sweet potatoes and lima beans. Some practitioners recommend that people with hypothyroidism (an underactive thyroid gland) avoid these foods, even though most have not been proven to cause hypothyroidism in humans. Because of the thyroid's effect on insulin secretion, prolonged intake of refined simple carbohydrates such as sugar, chocolate and other sweets can cause the overtaxing of your thyroid gland and lead to dysfunction. Our bodies were not designed to handle large amounts of refined food products and physiologically we pay the consequences when overindulging. Because of the resultant change in " endocrine output " taking birth control pills, epinephrine and cortisone, can also lead to thyroid dysfunction. Taking synthetic thyroid hormone for an inactive thyroid gland will tend to make your thyroid rely more on this outside source and will thus lead to further " inactivity " . It makes so much more sense to the author to find out and correct the cause of the dysfunction thus allowing the thyroid to heal and return to normal functioning. Overeating, especially refined inferior fats and sugars over prolonged periods of time will make the body produce more thyroid hormones (to increase fat burning and glucose uptake) than it can comfortably produce. This may inevitably lead to hypothyroidism. X-rays striking the thyroid (including dental x-rays) can damage the thyroid. Due to a decrease in the burning of fats, thyroid patients may tend to build up cholesterol deposits and be more prone to heart troubles. The sluggish circulation will also manifest in having cold hands and feet. Another stage of life at which thyroid disorders are more common is at menopause. Many women who experience depression and " brain fog " during menopause are told that these symptoms are caused by plummeting levels of estrogen. Yet " low levels " of thyroid hormone can produce 'identical symptoms'. (Other common signs of low thyroid function — at any age — include hair loss, weight gain, dry skin, slow heartbeat, and cold hands and feet.) If you're going through menopause and are suffering from depression, it's crucial to rule out hypothyroidism, because left untreated, hypothyroidism can " cause " dangerously high 'cholesterol levels'. An imbalance in the amount of estrogen in the body (be it due to pituitary, liver, ovary, or adrenal malfunction) can 'alter' thyroid function. Too little thyroid hormone production can lead to an imbalanced output of estrogen and progesterone by the ovaries, leading to prolonged and painful periods in women, with an increased tendency toward 'water retention'. -- Thyroid Hormone Receptors According to Dr. Erasmus, essential fatty acids are critical to thyroid function because, first, they are required for the integrity of the structure for every membrane of every cell. Second, they increase energy levels in the cell. And third, there is some evidence that essential fatty acids, especially Omega 3s, improve the " efficiency " of the hormones on the receptor sites. To understand the importance of the receptor issue, think about the situation of diabetes. Pre-diabetes, the condition that is considered a marker for future diabetes, is also known as insulin resistance. Insulin is in the body, but it isn't being utilized because saturated fats block insulin receptor function, and ultimately receptors become desensitized -- and ultimately immune to and unable to receive -- insulin. Essential fatty acids are required for receptor function and can make diabetics more insulin sensitive. So diabetics taking essential fatty acids may need less receptors, and ultimately, less insulin. Dr. Erasmus believes that this same mechanism takes place with other hormonal functions, such as the androgens, pineal glands, adrenal glands -- and specifically, the thyroid. There are practitioners who believe that thyroid hormone resistance is not a rare occurrence, and is actually a more common sign of impending thyroid disease, much like insulin resistance is a precursor to diabetes. This issue of receptors is critical, because according to Dr. Erasmus, " With proper essential fatty acid nutrition, what will sometime happen is that you get fewer receptors but they " work better " . " This would mean that proper levels of essential fatty acids might make the thyroid hormone receptors work better, so that thyroid hormone actually accomplishes its mission. Omega 3 fatty acids come from foods like green leafy vegetables, and cold water fish such as water packed sardines, and alaskan salmon, coho, Pacific and Atlantic herring, Atlantic mackerel, and lake trout. Omega 6 fatty acids are found in sesame, pumpkin and sunflower seeds and other raw seeds and nuts. When it comes to fish, Dr. Erasmus always prefers the fish themselves to fish oil supplements. According to Dr. Erasmus, since 1900, Omega 6 consumption has increased by about 20 times the previous levels, primarily because of increased use of certain " rfined " vegetable oils in food preparation, while Omega 3s are now only 1/6 of previous levels. This means that we get too much Omega 6 and too little Omega 3 fatty acids. www.udoerasmus.com --- L-Tyrosine is a direct precursor to Thyroxine, a primary thyroid hormone, as well as Adrenaline and Nor-adrenaline. Thyroxine has been found to increase metabolic rate and control growth rate. L-Tyrosine is a necessary amino acid in the production of neurotransmitters including epinephrine, norepinephrine, and dopamine. L-Tyrosine also appears to have a mild stimulatory effect on the central nervous system. Patients with a Thyroxine deficiency have symptoms including excess weight gain, cold hands and feet, and decreased basal metabolism. L-Tyrosine has been found to assist in optimizing thyroid hormone levels, increased mood, concentration, and productivity. L-Tyrosine is used to treat conditions including depression or mood disorder, poor coping ability, fatigue, low sex drive, low metabolism, and drug abuse (when combined with Tryptophan). It can also improve endurance under stress and is effective as an appetite suppressant. When taken properly, L-Tyrosine can assist a sluggish thyroid and aid the dieter in losing excess, unwanted pounds. The suggested dosage for healthy adults ranges from 500 to 1500 mg per day. Also beneficial - Flaxseed & Eveningprimrose oils– 2 capsules twice daily with food. --- Selenium tablets -xcellent source of trace minerals including selenium for those with a thyroid condition. Selenium is vital for the conversion of thyroxine (T4) thyroid hormone to its more active T3 form. The conversion of thyroxine to T 3 is controlled by the essential trace mineral selenium (Ref Am J. Clinical Nutrition 1993, Vol. 57) www.weightcontroldoctor.com --- Soybeans are high in phytic acid,a substance that can block the uptake of essential minerals -While it is true that soybeans are high in phytates, so are many plant foods such as other beans, grains, nuts and seeds, and it is true that phytates can block the uptake of essential minerals, and particularly zinc. This would be a problem if a person consumed large amounts of phytates; for example, if they ate nothing but soybeans or wheat bran. But the phytic acid levels found in a plant-based diet including a serving or two of soy a day are not high enough to cause mineral absorption problems for most people eating varied diets. Furthermore, when soy products are fermented - as they are in tempeh, miso, and many other soyfoods - phytate levels are reduced to about a third their initial level. Other methods of soy preparation such as soaking, roasting and sprouting also significantly reduce phytate content. While phytates can compromise mineral absorption to some degree, there is absolutely no reliable evidence that vegetarians who eat soyfoods " risk severe mineral deficiencies. " The complete adequacy of vegetarian diets is now so thoroughly proven and documented that even the National Cattlemen's Beef Association has acknowledged the legitimacy of meatless diets. In an official statement, these representatives of the beef industry declared, " Well planned vegetarian diets can meet dietary recommendations for essential nutrients. " While animal studies dating back to the 1950s suggest a link between soy and thyroid enlargement (goiter), the evidence that soy impairs thyroid function in humans is largely theoretical. In other words, we know that compounds in soy can affect thyroid tissue in laboratory studies, but what this means for living, breathing humans is less clear. Population studies do not show a greater prevalence of thyroid disease in countries with a high intake of soy, and while some clinical studies have found that soy depresses thyroid function in adults, other research has shown it actually *enhances* it. That debate aside, most researchers agree that consuming soy at the level needed to get its heart protecting benefits (about 25 grams per day) is unlikely to impair thyroid function. However, if you have a thyroid disorder such as hypothyroidism, a bit of caution may be in order. Try to keep your soy intake fairly constant, have your thyroid hormone levels monitored periodically, and if your levels fall below normal, consider reducing or eliminating soy from your diet. Also be aware that taking thyroid medication at the same time as soy foods or soy supplements may decrease the drug's absorption, so avoid taking the two together. It's true that excess consumption of soy can affect thyroid function, but this is of concern only if you have a thyroid problem to begin with. All told, I find the epidemiological data on soy foods very reassuring. I do not recommend soy *supplements* because of their high isoflavone content and the lack of epidemiological evidence for their long-term safety, especially if taken on top of soy foods and isoflavone -spiked nutraceuticals. The only people who might need soy isoflavone supplements are those who are allergic to soy, but they should first try eating tiny amounts of whole foods regular basis, then gradually increase the amount of soy to try to develop a tolerance. Excess consumption of soy can affect thyroid function, but is usually only a problem in those taking synthroid or other thyroid replacement medication. www.drwhitaker.com -- Chocolate is high in copper. It does not seem to be a good food for hyperthyroid patients as the high copper content would suggest. I developed a suspicion that chocolate is high in cadmium. Searching for medical studies on cadmium and chocolate led me to only two studies. The first study below is very suggestive that my suspicion is correct and that cocoa beans may be high in both cadmium and lead. The second study confirms that chocolate is high in cadmium (and also nickel). It's possible that the cadmium is introduced to the cocoa during processing, possibly by contact with galvanized containers, and is not natural to the food.
