Diatomaceous earth can be obtained naturally in fruits and vegetables. However, only about 1/3rd of the amount of silica needed by the human body can be obtained from foods due to the high consumption of hybrid and genetically modified foods as well as the fact that most of our nation’s food is grown in nutrient-depleted soils.
In an Alzheimer’s disease prevention study that lasted from 1992 to 1994, medical researchers from the Hospital Casselardit in Toulouse, France discovered that high concentrations of a silica supplement that has been derived from diatomaceous earth may be able to prevent or suppress the onset of Alzheimer’s disease.
This particular study involved 7,598 women that were over the age of 75 who had normal mental functioning at the beginning of the study. Women that concluded the study with normal or higher cognitive scores were followed for seven years. Of these women, 323 had maintained normal cognitive functioning throughout the seven years after the study, while only 60 of them had developed Alzheimer’s disease.
The women who did not develop Alzheimer’s disease were found to have a considerably higher dietary intake of silica, while those that developed the disease had a significantly lower intake of silica. As a conclusion of the study, researchers have suggested that a daily intake of silica can prevent Alzheimer’s by removing aluminum in the brain.
