Why The Magic of Manganese Isn't Just In The NameManganese is one of those elements commonly referred to as "trace" minerals within the human body, because they're found and required only in relatively tiny quantities. But that description should not be taken as reducing the importance of manganese in any way. Indeed the very name is derived from the Ancient Greek word for magic; evidencing the special powers which they attributed to it. Modern science is probably too cautious to go as far as that, but there's no doubt that manganese has a number of vital functions within the body. Manganese is an essential element in the production of a number of vital enzymes. Perhaps particularly important amongst these is superoxide dismutase, an anti-oxidant enzyme which has a crucial role in protecting the mitochondria of every cell in the body from the oxidative free radical damage which can lead to DNA damage, premature ageing and even, eventually, degenerative disease. Manganese dependent enzymes are also essential for the effective metabolism of protein and carbohydrates from the diet, as well as cholesterol. In addition to helping maintain normal cholesterol levels, it has also been noted that cardiac patients tend to have depleted levels of manganese in the heart muscle, and there is research evidence to suggest that manganese may also help protect against arterial damage. Manganese is also regarded as important for bone and joint health. Some commercial preparations containing glucosamine, a popular supplement marketed as an aid to joint flexibility and for reducing the pain of osteo-arthritis, also contain significant quantities of a manganese compound, and there's evidence that manganese, like glucosamine, has a significant effect in helping the repair of joint cartilage. Low blood levels and deficiencies of manganese have also been associated with an increased incidence of osteoporosis, ie brittle bones; and wound healing depends on prolidase, another manganese activated enzyme. Although orthodox medicine remains reluctant to accept the link, there is evidence that low levels of manganese are associated with the glucose intolerance characteristic of diabetes, and, coincidentally or not, it has also been noted that many so-called "natural" nutritional therapies for the disease are often based on manganese rich herbs. No one is claiming that manganese supplements may act as an alternative treatment for diabetes, but many practitioners maintain that when taken together with a manganese rich diet, they may well assist sufferers to manage their blood sugar levels. Finally, a number of research reports have confirmed an associative, but not necessarily causal, relationship between low manganese levels and brain (epileptic) seizures in both humans and other animals. Whilst it is generally recognised that more research is required, it seems reasonable to suggest that ensuring good levels of manganese in the body may have some protective effect. The US Food and Nutrition Board has recommended an upper safe limit for manganese intake of 11 mg a day for adults, and there are potential concerns about manganese toxicity. These appear to arise, however, from the direct inhalation of manganese dust and the consumption of manganese contaminated water or heavily polluted air, rather than from diet or supplements. These external pollutants apart, there is much more likely to be a deficiency of manganese than an excess. Whole grains, leafy green vegetables, certain fruits and green or black tea are reasonably good sources, but many modern Western diets may still struggle to provide even the minute amounts required. As usual, the stripping of nutrients from the soil along with our increased dietary reliance on heavily refined grains are the main culprits. But in the case of manganese this problem is compounded by its negative interaction with other essential minerals needed by the body in larger quantities. It appears, for example, that the absorption of manganese from food decreases in proportion with the amount of iron contained in that food, and the amount of iron stored in the body. Blood levels of both manganese and the important anti-oxidant, superoxide dismutase have been found to be reduced in individuals following a program of iron supplementation, and similar results have been found in people supplementing with magnesium, as is very commonly recommended in the interests of cardiac and cardiovascular health. Relatively high doses of calcium supplements have also been found to reduce the absorption of manganese and perhaps also increase its rate of excretion from the body. But none of the above effects should be taken as reasons not to supplement with these other minerals should such a program be regarded as potentially beneficial. They are, however, yet more evidence of the holistic operation of the body's systems and the mutual interdependence of all the many nutrients on which these rely. Thankfully, though, the answer to the problem is simple enough. It is to ensure that no supplements of minerals, or for that matter vitamins, are ever taken in isolation, but only in the form of comprehensive multi-vitamin and multi-mineral supplements. And of course, these should always be regarded as being in addition to a nutritionally well balanced diet rather than a replacement for it. Such a multi-mineral supplement should provide more than sufficient manganese but it is also worth noting that good intakes of both vitamin C and zinc, in particular, appear significantly to improve manganese absorption.

No Business Is Safe from Environmental DisasterProtect Your Assets and Future with Pollution Liability Insurance (ARA) - Fears that the environment will suffer under the Republican administration are misplaced, say the world's leading pollution liability experts. Thanks to privatization and the shift to state enforcement, pollution is being rapidly uncovered. Good news for Mother Nature -- devastating news for those footing the clean-up bill. The fact is, nearly every business -- from farms and schools, to contractors and developers, to printers and manufacturers--is a potential polluter facing third-party liability claims, clean-up costs, business interruption, and damaging publicity. That's according to the environmental insurance experts at Assurex International, the world's largest privately held risk management and commercial insurance brokerage group. Ironically, business owners who devote considerable resources building healthy organizations often risk it all by neglecting pollution liability insurance coverage. They mistakenly believe their companies are free of environmental exposures, or that pollution coverage is unavailable or unaffordable. Both assumptions are false and potentially costly to businesses large and small. Former and current land and business owners, waste generators and transporters all can be held liable for environmental exposures. "Acquire a company that buried tanks 15 years ago, construct homes on arsenic-laced farmland, build a school on toxic land, and you'll share liability with the polluter--unless you have environmental liability insurance," notes Assurex President and CEO Thomas W. Harvey. Environmental insurance helps offset costs associated with pollution clean-up, business interruption, lawsuits, construction delays and property value diminution. "Environmental insurance can mean the difference between business survival and devastating financial loss," says Harvey. You don't have to be a chemical manufacturer or other big operation to be at risk of environmental liability. Businesses large and small are potential polluters. For a small, neighborhood grocery store, just one broken bottle of ammonia could release fumes, overcome shoppers, and create potential liability problems. On a somewhat larger scale, take the case of the entrepreneur who bought an aging fast-food restaurant. While remodeling, the new owner discovered underground storage tanks buried 20 years earlier when a gas station sat on the site. The new and previous owners shared responsibility for removing the tanks at a cost of $20,000 to $1 million-plus. With an environmental liability insurance policy in place, clean-up costs might be covered. Large organizations experience environmental surprises, too. When construction began on a $200 million school complex in Los Angeles, officials had no idea their state-of-the-art learning center sat on toxic land. Once environmental contamination was uncovered, construction on the nearly complete building stopped. Had a site survey been conducted prior to construction, this costly disaster might have been avoided. While a site survey should be part of any merger, acquisition or real estate transaction, surveys sometimes fail to unearth exposures. Environmental insurance, on the other hand, is a certain way to transfer risks and mitigate financial losses. According to Brad Maurer, an environmental insurance expert with New York City-based Assurex Partner Frenkel & Co., most business executives would be surprised to learn what's covered by an environmental insurance policy. "Insurance can cover existing exposures today, as well as future risks. Even known environmental conditions may be covered, if surveys indicate there is no immediate health threat," notes Maurer. "Environmental insurance policies are becoming popular tools for real estate and business transactions," adds Maurer. "Environmental insurance allows buyers and sellers to transfer a deal's environmental risk to an insurer, rather than wasting time and money negotiating who will bear and fund the risk."
