Articles about diatomaceous earth

The articles below have been written by Vets, Researchers, and users of pure food grade DE.

I am offering them only as information that others have experienced and research by those in the medical and scientific community. I tried to list them in alphabetical order according to the Title.

Difference between Bentonite Clay and Diatomaceous Earth.

"Many harmful things entering the body have a positive charge. Silica is a semi-conductive mineral which when warmed by body heat becomes negatively charged and gives off electrons. These negatively charged mineral ions and/or individual shells attract bad microbes, free radicals, positively charged waste and other harmful things. Acting as magnets, the negatively charged shells and/or ions attract and absorb positive things that are small enough to go through the holes. Add a sugar molecule and you can trap toxins into the porous food-grade DE particle which is then excreted safely out of the body. Because of the strong charge, each shell can absorb a large number of positively charged substances, whether they be chemical or in the form of bacteria or viruses. They pass on through the stomach and intestine, taking these harmful substances out of the body." From the Difference between Bentonite Clay and Diatomaceous Earth. Source:

Diatomaceous earth lowers blood cholesterol concentrations.

In this study a potential influence of diatomaceous earth to lower blood cholesterol was investigated. During 12
weeks we monitored serum lipid concentrations in 19 healthy individuals with a history of moderate
hypercholesterinemia (9 females, 10 males, aged 35 - 67 years). Individuals administered orally 250 mg
diatomaceous earth three-times daily during an 8 weeks observation period. Serum concentrations of cholesterol,
high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and triglycerides levels were measured
before study entry, every second week during the period of diatomaceous earth intake and 4 weeks after stop of
intake. Compared to baseline (285.8 +/- 37.5 mg/dl = 7.40 +/- 0.97 mM) diatomaceous earth intake was
associated with a significant reduction of serum cholesterol at any time point, reaching a minimum on week 6
(248.1 mg/dl = 6.43 mM, -13.2% from baseline; p<0.001). Also low-density lipoprotein cholesterol (week 4:
p<0.05) and triglycerides levels decreased (week 2: p<0.05, week 4: p<0.01). Four weeks after intake of
diatomaceous earth was stopped, serum cholesterol, low-density lipoprotein cholesterol and triglycerides still
remained low and also the increase of high-density lipoprotein cholesterol became significant (p<0.05).
Diatomaceous earth, a bioproduct, is capable of reducing blood cholesterol and positively influencing lipid
metabolism in humans. Placebo-controlled studies will be necessary to confirm our findings. Source:

Study on Mole Crickets:

Crickets treated only with the high doses (108 conidia per cricket) of each of the three B. bassiana strains exhibited the shortest survival times as well as the highest percentage mortality at 28 d after treatment. However, these treatments did not differ significantly from any of the diatomaceous earth combination treatments. Two of the strains tested, 5977 and 3622, exhibited synergistic interactions with DE, whereas the third strain, GHA, was not significant for synergy



Grain Storage:

Quote from the Bob Livingson Letter - Special Issue.

I will share with you a grain storage idea that really works. It is a personal story.
Many years ago we went into the rice fields of Louisiana and bought 2000 lbs of rice. It was brown rice with only the husk gone, not polished into white rice. Brown rice is an excellent, nutritious food and easy to store for long periods. We then bought a nontoxic and tasteless powder called Perma Guard (diatomaceous earth). We put the rice into metal barrels with brown meat wrapping paper next to the barrel wall and saturated the rice with Perma Guard. Perma Guard keeps the grain dry and dehydrates any bugs or insects that may get into the barrels. Stored grains have to be preserved with low moisture content. Well, we raised our children on nutritious brown rice that cost us ten cents a pound. We also shared the rice with family. It didn't require all that much effort, but it had long-term value. We still enjoy brown rice as perfect as it was 37 years ago.

Diatomaceous Earth Wrecks Insects' Internal Water Balance USDA

What's a natural way to kill insects in food processing plants? The answer has been around for 20 million years: diatomaceous earth (DE). But DE isn't earth--or even dirt. It's the broken-up shells of tiny plants, called diatoms, that lived in the sea roughly 20 million years ago. Today, these fossilized skeletons are being combined with heat treatment as an alternative to methyl bromide for controlling insects in flour mills and other food processing plants.

"Turning up the heat creates one big oven for the insect pests. The heat breaks down the waxy layers of their exoskeletons, and the DE absorbs the layers, disrupting their internal water balance. Without this delicate balance of water, insects can't survive," says Agricultural Research Service entomologist Alan K. Dowdy. He's at the agency's U.S. Grain Marketing and Production Research Center in Manhattan, Kansas.

In 1996 lab studies, Dowdy found that 98 percent of red flour beetles were killed when exposed to 122oF and DE. This insect is noted for tolerating heat under normal conditions. The study then became the springboard for a 1997 joint U.S.-Canadian field research project at Quaker Oats of Ontario, Canada. For the field test, the researchers placed confused flour beetles--one of the industry's worst insect invaders--in the processing facility. One hundred percent of the beetles died within a day after exposure to a temperature of 115oF and DE. The payoff for the food industry: Cost of heat treatment may be lower, and insect control is better using DE and heat, compared to using heat alone. Both Canadian and U.S. food processing plants have used heat treatments, but a few processors are concerned about expensive installation of new heating systems in older buildings. The researchers showed that lower temperatures could be used with DE and still control insects.
