Vitamins C and E Won’t Reduce Your Risk of Dementia
Posted by: Dr. Mercola

Taking vitamins C and E is not an effective method to prevent dementia, including Alzheimer’s disease.

It has been suggested by researchers that the development of dementia, caused by the progressive death of brain cells, may be influenced by the formation of free radicals. As these free radicals are blocked by antioxidants such as vitamins C and E, some believe that taking these supplements may reduce the risk of developing this disease.

But, as shown by a new study of over 2,000 Japanese-American men, this is not the case. The men, who were born in the early 1900s, were questioned about their intake of supplements. There was no decrease in risk of dementia among men who took both vitamin C and E for short- or long-term periods as compared with those who took no supplements. Taking the vitamins separately did not result in an association either.

Dementia affects some five percent of Americans aged 65 years or older. Researchers say that further studies are needed to determine whether taking supplements long-term will influence the risk of dementia.

More evidence to support my minimalist approach when it comes to taking supplements. I am not opposed to supplements but to the belief of many that diet can be ignored and magic pills relied upon to prevent disease. Those who believe this justify the approach by saying that all soils are depleted, and it is not possible to obtain healthy vegetables anymore.

Pure fantasy.

Whole foods have many components in them that are currently recognized as beneficial to health. While it is possible to identify some of the more important constituents, it will be many generations before we understand diet enough to provide supplements that are fully equivalent to whole foods. The largest missing link is the energy component in foods, which I wrote an article on earlier this year. Please review my article from last issue for details on how to tell if you have too much iron in your system.

Earlier studies have provided convincing evidence of the importance of whole foods in preventing Alzheimer’s disease. It is likely that the antioxidant capacity of whole foods is one of the major mechanisms by which they are beneficial. However, relying on a supplement to provide this benefit is frequently a non-effective approach.

I have recently learned that one of the most potent influences on the creation of free radicals is excess iron. Iron is needed by one-third of the world as an essential nutrient, but for the other two-thirds it can be a toxic poison. So if you are a non-menstruating woman or an adult male, it is highly likely that iron is your enemy, not your friend, and should be avoided in any supplemental form.

Iron is also one of the strongest biological toxins because of its ability to react with oxygen to form reactive oxygen species. Excess iron will generate the most potent free radical in the body called hydroxyl radicals. Once these radicals get loose, they wreak pure havoc in the body and destroy everything in their path.

So one of the most effective strategies is proactive prevention. Rather than relying on having enough antioxidants on board to fight the free radicals, it makes much more sense to prevent the production of free radicals in the first place. One of the best ways to do this is to make sure that your iron levels are not elevated, as previous studies have shown that excess iron accumulation in the brain is a consistent observation in Alzheimer's disease.

Other preventive options follow:

  • Exercise is a very potent way to ward off Alzheimer's. Previous research showed the odds of developing Alzheimer's were nearly quadrupled in people who were less active during their leisure time between the ages of 20 and 60 compared with their peers. That is one of the reasons why I have been exercising for the last 34 years and, God willing, hope to continue for another 50.
  • Getting the mercury amalgams out of your teeth is another effective strategy along with avoiding aluminum -- these are the classic recommendations.
  • Following the nutrition plan and eating plenty of fresh vegetables with high folate levels.

The key to treating Alzheimer's is to make sure you never get it. So, just how do you prevent Alzheimer's?
