Are Sea Vegetables the Cure for the Iodine Deficiency Epidemic? Author: Joseph Pizzorno, ND - November 2009 Iodine deficiency epidemic Although most of us believe we are not deficient in iodine since the fortification of salt with iodine, the fact is most people are deficient and don't know it. Due to changes in food intake, eating patterns and food production methods, iodine intake has been decreasing in the U.S. since the early 70's. Even worse, we are exposed to increasing levels of environmental toxins that either block the absorption of iodine or block its actions in the body. According to the National Health and Nutrition Survey (NHANES), 24-hour urine levels of iodine have decreased from average levels of 320 mcg/L during 1971-1974 to 165 mcg/L in 2001-2002 – a drop of almost 50%.1,2 NHANES (2003-2004) found a urinary iodine level of <50 mcg/L in 12% of the U.S. population, indicating severe deficiency (<100 mcg/L is indicative of deficiency).3 Iodine levels in the breast milk of nursing mothers in Boston showed that only 47% contained sufficient amounts of iodine to meet infant requirements.4 This dramatic drop in iodine intake is made worse by an increasing level of iodine uptake inhibitors - perchlorate, nitrate, and thiocyanate - in the food supply and environment. Why has iodine disappeared from our diet?Iodized salt is very effective in normalizing iodine intake. The problem is we eat less iodized salt. This has occurred for 2 reasons: first, we've all been told to decrease salt intake because excess consumption can elevate blood pressure. However, the more important cause is that almost everyone now eats more processed foods and meals at restaurants—most of these do not use iodized salt! This is made worse by the fact that the iodized salt sold for home use often contains less iodine than stated on the label and two other good sources of iodine, bread and milk products, now contain very little due to changes in how they are produced. Dairy products used to contain a significant amount of iodine since it was used to disinfect cow udders and dairy processing equipment. Now, however, antibiotics and other methods are used instead. In addition, less iodine is used in feed supplements. With these changes, the average iodine content of U.S. whole cow's milk had decreased from 602 mcg/L in 1978 to 155 mcg/L in 1990. A 2002 study found as little as 88 mcg/L, less than 15% of those measured in 1978.5 This is worsened by the substitution of soft drinks for milk by children, adolescents and adults so we drink less milk which has less iodine.6,7,8 Another significant source of iodine in the past was bread since iodated-based bread conditioners were used to prolong shelf life. Today, most commercial bakeries are using bromated-based conditioners instead. Iodized salt may have less than we think because it evaporates over time from salt containers and shakers.9 The rate of evaporation is increased by humidity and heat. In the summer in humid areas of the country, the half life of iodine in salt can be as little as one week! Many in the natural products field use sea salt as a supposed better alternative to regular salt. Unfortunately, it is not iodized. What happens when iodine levels are too low? Everyone is aware that iodine is required to produce thyroid hormones, so if levels are too low people suffer hypothyroidism. This is one reason the incidence of clinical and subclinical hypothyroidism affects 10-15% of the population, especially women. Probably more prevalent are the other problems found in people with low to marginal levels of iodine. It is well known that low iodine levels in fetuses and children leads to impaired mental development and research has now shown an increased incidence of fibrocystic breast disease and breast cancer.10,11 Some research has also shown that iodine deficiency may contribute to obesity, attention deficit hyperactivity disorder (ADHD), psychiatric disorders, and fibromyalgia. Are seaweeds/sea vegetables a good source of iodine? Although sea vegetables, i.e., seaweed, are common in many traditional diets - especially the Japanese, they are not commonly consumed in the U.S. Most people think of sea vegetables as a food source for iodine. Some are, but many aren't, and you have to eat more than just a few sprinkles. Also, some may be contaminated with toxic metals. As the table below shows, the amount of iodine in seaweed varies greatly.12
Bottom Line Iodine deficiency is a common and growing problem in North America. Fortunately, eating enough of the right kind of seaweed will replenish iodine supplies. References

Sugar tastes sweet, but it can lower your immune system. Oh so sweet! Some interesting information on the relationship between sugar and its effects were covered in USA Today. They report that a big dose of sugar can immediately suppress your immune system and make you more vulnerable to colds, flu and other infections. So, at a time when people are especially keen to protect themselves from H1N1, or swine flu, it's worth asking: Is it true? Can a few spoonfuls of sugar really help make you sick? Denver nutrition therapist Kate Pfeiffer has no doubt. "Limiting sugar should be the first line of defense against infectious disease," she says. She wrote a column that is worth reading titled: "Worried about the Swine Flu? Avoid Sugar!" In it she cites a 1973 study, published in the American Journal of Clinical Nutrition and other references. In the study, researchers at Loma Linda University gave volunteers 100 grams of sugar (20 teaspoons, roughly the amount in a liter of soda). The researchers then drew blood from the volunteers and mixed in some bacteria. They found that infection-fighting white blood cells from people who had just gorged on sugar gobbled up many fewer bacteria than those who had just fasted or eaten an unsweetened starch. But that's not evidence that would convince most doctors, says Aaron Glatt, an infectious-disease specialist who is president and chief executive officer of New Island Hospital in Bethpage, N.Y. Glatt says he has heard of the sugar theory, but as far as he knows, there are no studies showing people who eat a lot of sugar actually get more cases of colds and flu. However this is contradicts the references outlined in Ms. Pfeiffer's article. He says: "There are numerous other reasons people should be concerned about sugar intake," including the prevention and control of obesity and diabetes. But, he says, "there's no reason not to drink a glass of soda just because someone next to you is sniffling." This puts more emphasis on a balanced diet. While it's unlikely any one food is the key to a strong or weak immune system, we can optimize the building blocks for immune system by eating a healthy, balanced diet. Experts agree wholeheartedly that overall nutrition is more important than any one substance. But there's something about a sugar overdose that makes people vulnerable. All these statements being true, it is interesting that American Dietetic Association and other health groups suggest lower intake of sugars. We'll expect to see some evidence soon — when doctor's offices fill up with sick kids after Halloween. Issue of note: The above leads us to caution you on another issue. CAOH® has a competitor that is marketing an Acai juice product that has the same name as our juice, "Acai Max". Acai Max® is the name of our very popular organic acai juice blend. We have been producing our acai juice product since 2004 and the product name "Acai Max" is our registered trademark! This other party not only produces a juice that is more expensive and less potent in the primary ingredient Acai, but they add cane juice to it. Now many of you will ask, what is cane juice? Cane juice is juice squeezed from sugar cane, which is then dried (dehydrated) and used to make cane sugar - yes SUGAR! Cane juice is nothing more than sugar! Now there is a new movement to push cane juice as a healthy choice to refined sugar, but the fact remains that it is still sugar. Other than it being sweet there is no nutrition in cane juice or sugar. So they are basically overtly adding sugar to their acai juice. So please remember if you do not see "California Academy of Health" on the bottle - it is not our product and may have unwanted additives. Thanks, CAOH!

WASHINGTON - Millions of U.S. children have disturbingly low Vitamin D levels, possibly increasing their risk for bone problems, heart disease, diabetes and other ailments, according to two new studies that provide the first national assessment of the crucial nutrient in young Americans.
About 9 percent of those ages 1 through 21 — about 7.6 million children, adolescents and young adults — have Vitamin D levels so low they could be considered deficient, while an additional 61 percent — 50.8 million — have higher levels, but still low enough to be insufficient, according to the analysis of federal data being released Monday.
"It's astounding," said Michal L. Melamed of the Albert Einstein College of Medicine in New York, who helped conduct one of the studies published online by the journal Pediatrics. "At first, we couldn't believe the numbers. I think it's very worrisome."
Low Vitamin D levels are especially common among girls, adolescents and people with darker skin, according to the analysis of a nationally representative sample of more than 6,000 children. For example, 59 percent of African American teenage girls were Vitamin D deficient, Melamed's study found.
CAOH® Power D3™ soft-gels supply 1000 IU of vitamin D3 (Cholecalciferol). This important vitamin is in a highly-absorbable liquid soft-gel form. Vitamin D is normally obtained from the diet or produced by the skin from the ultraviolet energy of the sun. However, it is not readily abundant in food. As more people avoid sun exposure, Vitamin D supplementation becomes even more necessary to ensure your body receives an adequate supply.

Multivitamins Reduce Blood Pressure

Diseases of the heart and circulation are so common and the public is so well acquainted with the major symptoms that result from cardiovascular disorders that patients, and occasionally physicians, wrongly attribute many unrelated complaints to cardiovascular disease (CVD). It should not be a surprise that this occurs, as most patients are aware that cardiovascular disease remains the leading cause of death in the United States.
There are four principle properties of the cardiovascular system that can be evaluated to provide information to help manage cardiovascular disease. These include movement of electrical signals through the heart, heart pump function, blood flow through the heart, and anatomy. There are several risk factors for cardiovascular disease that are essentially undeniable. These are older age, male gender, and a family history of CVD. Additionally, three major risk factors identified include cigarette smoking, dyslipidemia (high cholesterol), and hypertension.
By definition a multivitamin is a preparation intended to supplement a human diet with vitamins, dietary minerals and other nutritional elements. A multivitamin/mineral supplement is defined in the United States as a supplement containing 3 or more vitamins and minerals but does not include herbs, hormones, or drugs, with each nutrient dosage below the tolerable upper level determined by the Food and Drug Board (FDA). People with dietary imbalances may include those on restrictive diets and those who can't or won't eat a nutritious diet. Pregnant women and elderly adults have different nutritional needs than other adults, and a multivitamin may be indicated by their physicians.
A recent study was done involving 128 obese Chinese women aged 18-55 years having an increased risk of cardiovascular disease by having hypertension, hyperglycemia or hyperlipidemia. It was a 26-week randomized, double-blind, placebo-controlled trial with the subjects receiving either one tablet of high-dose multivitamin and mineral supplement (MMS), or one tablet of low-dose MMS (Low MMS), or calcium 162 mg (Calcium) or identical placebo (Placebo) daily. The results showed that supplementation with adequate multivitamin and mineral supplement could reduce blood pressure and serum CRP in obese women with increased cardiovascular disease risk. (1)
