Iodine deficiency: 2 billion people to support
lodine is an essential element tor living animals and the human diet but nowadays is hardly present in the Earth's crust. Over hundreds of millions of years the iodine that was present has been leached out of the soil by floods and melted glaciers that carried it back to the sea which in turn has become progressively enriched with this element.
lodine is to be tound in the chemical structure of thyroid hormones (thyroxine or T4 and triiodothyronine or T3), which influence the correct functioning of the thyroid. In order to ensure that the thyroid functions correctly it is necessary that everybody - children, teenagers and adults - takes the recommended daily allowance of iodine which is in Europe 150 micrograms tor teenagers and adults and 250 micrograms tor pregnant and lactating women.
In 1996 WHO (World Health Organization) estimateci that iodine deficiency affected 30% of the World's population1.
The Iodine World
Food is the best source to obtain iodine. Sea fish, shellfish and seaweed, as well as milk, meat and eggs are good sources of iodine. Lower percentages are tound in fruit and vegetables. lodine content of seaweedsvaries from 16 ppm to 8165 ppm, the highest iodine containing seaweeds being the genus Laminariales. lodi ne content varies with age and condition of the plant, with iodine loss to occur rapidly once a seaweed is no longer growing.
Geographic variation in iodine content is also a factor: tor example, Laminaria from South Carolina has 5 times less iodine respect to French Laminaria2.
However, another factor to consider tor iodine intake is its bio-availability, as our body only absorbs certain types. And it is necessary to differentiate between organic and inorganic iodine.
Actually more tood program advice to use the iodized salt to reduce the lack of iodine, but this is INORGANIC IODINE. Seaweeds conta in both inorganic and organic iodine: the organic one ranges from 10 to 30%3. ORGANIC IODINE in brown seaweeds is dominateci by hormone-like tyrosine derivatives, such as monoiodotyrosine and diiodotyrosine, precursors of the thyroid hormones T3 and T44. Organic iodine is less fast in absorption but is a slow released compound.
Recent studies demonstrates that Organic lodine from seaweeds is really bioavailable5 and so seaweeds are the best natural source of dietary iodine6.
So, rethink the possibility to have enough iodine, in bioavailable torm, not only from fish or milk but tor example through a good cup of tea.
Tea all over the World
Tea is a very well recognized and consumed beverage al around the world and it was createci in China more than 5000 years ago.
For colder countries, tea can be served hot after a hard day of work to have a moment to relax. In warmer climates, iced tea is very common. Tea is not just a simple beverage: is a way to have relax.
Tea is an old habit of humans, mainly between Asian people: through a simple infusion of herbals you can obtain many beneficial components such as vitamins, minerals, or iodine and the hot temperature is a valuable help tor the throat mainly in winter.
Tea and Seaweed
Blends of seaweed and tea aren't so uncommon; in fact Asian people normally have infusion of seaweed. This easy way to drink herbals can give people the opportunity to have iodine: more or less the 90% of the iodine from seaweed comes into the water.
For example try AlgeaFood I-Plus in a herbal Tea tor your wellbeing:
Combine all the ingredients in a infuser or in a tea bag.
Put into a kettle 200 ml of water and bring it to boil.
When it comes to a boil switch off the heat.
Pour the hot water into a cup and put in the bag of herbal tea/infuser.
Let steep tor 3 minutes betore drinking.
Add milk or sugar to taste your wellbeing tea with lodine.
Test to Evaluate the Iodine Biovalability of AlgeaFood I-Plus
AlgeaFood I-Plus is a natural phytocomplex made from pure Ascophyllum nodosum, that Algea directly harvests in cold and pure water of Norway.
The synergy createci between iodine, vitamins and alginates naturally present in AlgeaFood I-Plus makes it a super ingredient tor supplements and functional toods; To obtain iodine trough tood you have to be sure that is bioavailable tor human body.
To test the bioavailability of iodine in AlgeaFood the Endocrinology Department of the University of Pisa, developed the protocol schedule: we selected a sample of 18 healthy people with no thyroid-related pathologies and we randomly gave each subject a jar of tablets, which contained AlgeaFood tablets in some cases and identica[ placebo tablets in other cases.
Each AlgeaFood tablet contained 50 mcg of iodine and the subjects took these tables tor three weeks:
Then, in the fourth week (T4), no tablet was taken to verify if the iodine amount decreased. At the end of each week, urine samples were taken. The same procedure was applied to the group taking placebo tablets.
To determine if AlgeaFood I-Plus iodine is bioavailable the researchers analysed the iodine content (ioduria) in the urine.
This method is also used by WHO to assess iodine deficiency of the worldwide population.
AlgeaFood I-Plus: iodine naturally bioavalailable
Subjects who have taken the AlgeaFood tablets (probands) show a dose-relateci increase of iodine with respect to the basal samples. Then, at the end of the treatment (T 4). the concentrati on of iodine goes back to the basal values.
The results show a significant increase of ioduria (about three times) in the subjects who have taken the AlgeaFood tablets compared to the subjects who have taken placebo tablets.
Using AlgeaFood I-Plus as a natural source tor optimal organic and inorganic iodine intake means to significantly contributes to the amount of iodine necessary.
