What you need to know about iodine

The devastating earthquake and tsunami in Japan has led to fears of nuclear destruction and an increasing talk about iodine. It is important to understand that not all forms of iodine are the same, and different types of iodine will concentrate in different tissues and glands within the body.

In the event of a nuclear meltdown where radioactive iodine is released, potassium iodide is what is needed to protect the thyroid from the damaging effects of radioactive iodine. Potassium iodide has a strong affinity to the thyroid gland and will saturate the tissue preventing the absorption of the radioactive iodine. There are potassium iodide products that are made specifically for such a situation, which is why it is recommended to rely on such products and not to substitute with what could be far inferior products. One must use caution because the potassium iodide used for protection against radioactive iodine comes in an adult dosage of 130 mg (milligrams) tablets. Someone can mistakenly purchase a potassium iodide product off of a vitamin store shelf containing less than 200 mcg (micrograms), far less than what would be needed.

Potassium iodide can only protect the thyroid from radioactive iodine, not other parts of the body. Potassium iodide also cannot protect the body from radioactive elements other than radioactive iodine. If radioactive iodine is not present, taking potassium iodide is not protective.

Aside from iodine being used as a thyroid blocking agent, iodine preparations have many other uses supportive to one’s health due to its antibacterial, anticancer, antiparasitic, and antiviral properties. The iodine which is used in supplementation is in the form of iodine, potassium iodide, or combinations of both.

Historically, receiving the benefits of iodine through supplementation was problematic due to the fact that iodine itself is not very soluble in water. This made it difficult to get iodine into a solution which used water as a solvent. Then in 1829, Dr Jean Lugol discovered that potassium iodide added to water increased the solubility of iodine. This led Dr Lugol to create and begin using a solution for infections known as Lugol’s solution, which was a mixture of 5% iodine and 10% potassium iodide in water.

The combination of iodine and its reduced form, iodide, led to another benefit and is a major reason why certain iodine preparations utilize such combinations today. Different tissues of the body actually prefer one, or both, of these forms of iodine.

Since potassium iodide has a high affinity and ability to concentrate in the thyroid tissue, it is used as a thyroid blocking agent. Conversely, iodine itself is concentrated much more efficiently in areas such as prostate gland and breast tissue. Thus using a product that is purely potassium iodide might not give you the benefits you are looking for in the prostate and breast regions of the body.

For reasons of supporting your overall health and taken on a daily regimen, combination products that utilize both iodine and potassium iodide are what is recommended. For reasons of protecting the thyroid gland from the event of a nuclear event, then a highly concentrated potassium iodide product should be used under the guidelines and recommendations provided with the product.

Alzheimer's may begin in liver

A brain plaque caused by deposit of amyloid in the nerve cells of the brain.

The plaques, believed to be characteristic of the debilitating Alzheimer’s disease, starts in the liver rather than in the brain, a new study says.

Amyloid, the main substance in brain plaques associated with Alzheimer’s, originates from the liver, not the brain. The mind robbing disease, thus, can be treated outside the brain, said researchers at the Scripps Research Institute and ModGene, L.L.C. 

Greg Sutcliffe and colleagues used a mouse model for Alzheimer’s disease to identify the genes that influence the amount of amyloid accumulated in the brain.

Three genes protect mice from the accumulation and deposition of amyloid in the brain. Lower expression of these genes in the liver prevents the formation of amyloid plaques in the mouse’s brain, the scientists wrote in the Journal of Neuroscience Research.

“We reasoned that if brain amyloid was being born in the liver and transported to the brain by the blood, then that should be the case in all mice and one would predict in humans, too,” said Sutcliffe, adding that blocking the production of beta amyloid in the liver may protect the brain.

Injecting Gleevec, a new drug used for treating leukemia and gastrointestinal tumors, reduces the production of beta amyloid both in the blood and brain of the studied AD mice, the study found.

“This unexpected finding holds promise for the development of new therapies to fight Alzheimer’s,” the lead author said.”This could greatly simplify the challenge of developing therapies and prevention.”

Tomatoes combat killer diseases – and are even more potent when cooked

Eating tomatoes can help reduce the risk of cancer, osteoporosis and cardiovascular disease, scientists have revealed.

Not only that but cooked or processed tomatoes are actually better for you than raw ones.

U.S researchers found the juicy vegetable is the biggest source of powerful antioxidant dietary lycopene, and unlike other fruit and vegetables it has greater potency after it is cooked.

Scientists at the National Centre of Food and Safety in Illinois said the nutrient contains protective mechanisms that help prevent inflammation and blood clots.

A strong link has already been established between the wonder veg and a lower risk of certain diseases such as prostate cancer, heart disease and osteoporosis.

Dr Britt Burton-Freeman and and Dr Kristin Reimers, who carried out the review, said: ‘Leveraging emerging science about tomatoes and tomato products may be one simple and effective strategy to help individuals increase vegetable intake, leading to improved overall eating patterns, and ultimately, better health.

‘Research underscores the relationship between consuming tomatoes and reduced risk of cancer, heart disease, and other conditions.’

‘The evidence also suggests that consumption of tomatoes should be recommended because of the nutritional benefits and because it may be a simple and effective strategy for increasing overall vegetable intake.’

The review article will appear in the American Journal of Lifestyle Medicine.

Spray-on Skin Is a Reality

The skin gun is not science fiction—it’s a prototype medical device that literally sprays skin cells onto burn victims to re-grow skin. Old methods like skin grafts took weeks to heal; the skin gun needs about an hour.

We’ve heard about the spray-on skin gun back in 2008 but we didn’t think it’d become this real, this useful, this fast. Though it is still technically in an experimental stage, the skin gun has already successfully treated over a dozen burn victims. The way it works is by using stem cells from the patient’s healthy skin and mixing it with a solution to come up with the spray paint. And combined with that fancy gun, the rest is easy. Doctors say “skin cell spraying is like paint spraying”.

The video has some graphic burn images, so don’t watch unless you have the stomach for it. This clip will also air on National Geographic’s Explorer: How to Build a Beating Heart. Stem cells have long been a point of controversy but this is really wonderful science at work.
