Two large epidemiologic studies found less risk of Alzheimer’s disease when OSA levels in drinking water were greater than 10 ppm, even despite elevated aluminum levels ( Gillette-Guyonnet, S, et al. Exley, C Alzheimer’s and Dementia Summit 27.18 to 29.12 min. OSA, which is readily absorbed by humans, facilitates the elimination of aluminum in urine and perspiration ( Bellia, JP, et al. The same holds true for humans: people who drank 960 mcg of OSA (10ppm) in 100 cc of orange juice taken orally along with a test dose of 30 mcg of aluminum had 85% lower blood aluminum levels compared with control subjects who ingested aluminum alone without OSA ( Edwardson, JA, et al. Thirty years ago, researchers discovered that elderly rats fed OSA in their diet did not accumulate aluminum in their brains ( Carlisle, EM, and Curran, MJ Alzheimer Dis. Silica can assume a variety of chemical compositions, an example of which is water-soluble orthosilicic acid (OSA). Aluminum exposure increases homocysteine in the blood causing plaque to build up in the endothelium, resulting in atherosclerosis.įortunately, silica-a dissolved oxide of silicon- can provide a safe, readily available, and inexpensive means of protection from aluminum toxicity. It’s no friend to the cardiovascular system, either. It’s well known that aluminum is rough on the brain. In addition, brain autopsies of Alzheimer’s patients show elevated aluminum levels in brain regions suffering the most neuronal loss. (2014) 8:41 ).Īll seven of the largest epidemiological studies comparing aluminum in drinking water with incidence of Alzheimer’s disease found a significant dose-dependent correlation. Levels at two times that average can cause memory loss and Alzheimer’s disease ( Exley, C and Vickers, T J. That’s approximately 300 mcg of aluminum in an average 70-year-old human brain. On average, a lifetime of aluminum exposure will result in accumulation of 1 mcg per gram dry weight of brain tissue. It is estimated that even after 50 years, 4% of any aluminum ingested today will still be present in the body.
Like many toxic metals, aluminum accumulates over the course of a lifetime. A small amount, resulting in only 63 mcg/L in a person’s cerebrospinal fluid, will cause unconsciousness. Al 3+) in water are toxic to algae, fish, and human cells, especially neurons.Īs a neurotoxin, aluminum is no joke. Silicon’s main life-promoting role is to protect us from aluminum, the third most common element in the earth’s crust.Īluminum ions (i.e. In fact, we would not live very well–or very long–without it. Though it is not one of the fundamental building blocks of life like Carbon or Iron, it plays an essential role in our biology. Silicon is the second most abundant element in the earth’s crust.
