Food grade diatomaceous earth is frequently added to flour to kill bugs that might get into it, and to prevent eggs from hatching. Although we like to think processed food is perfect and completly free of insects (among other things) it still has to be grown somewhere where bugs can get to it and be ground up with it. DE helps lower the percentage of live insects and spoiled food. It is also a safe insectiside, and is used in houses to help control bed bugs and in coops to control ticks and lice. I add a small dusting of DE to the corners of the coop before I add clean litter. Dustbathing a hen afflicted with lice is an effective treatment if both the coop and the hens are dusted several times untill the lice are gone.
The reason DE is so good at killing insects is because of what it is- ground diatom fossils. The remains/fossils of the diatoms is a form of silica, the main ingrediant of sand. It is crumbly even before being pulverised for commercial use, and it cannot harm us unless breathed in large quantities. It will only irratate our lungs (unless breathed constantly inlarge quantities) and does not hurt our stomach orintestines at all, but its effect on bugs is much more harmfull. Although you cannot see it, on amicroscopic level DE grains are very sharp. When an insect walks over it, the DE works its way through the slits in the exoskeleton plates, aided by the by the bugs own movemant. Once inside the insect, the DE rubs against the organs and scratches them. The bug becomes dehydrated because it cannot keep water from evaporating out it's wounds and dies. It is a painful death for the bug.
DE is only effective if it is dry. Water causes DE to clump and harden into crumbly lumps, and insects wont be harmed by it. In a garden setting, the DE eventually sinks into the ground and spreads out among the plants, harmless. Worms and slugs will not be injured by the buried DE, as it is in such a small percentage, spread throughout the soil, that it is inefective. It also wil not harm the plants.
In fact, there seem to be many health benefits attributed to DE. Many people eat it as a supplement because the cylinder shape DE has on a microscopic scale supposedly "has a very strong negative charge. As these millions of cylinders move through the stomach and digestive tract, they may attract and absorb fungi, protozoa, viruses, endotoxins, pesticides, drug residues, E.coli, and heavy metals.
These are trapped inside the cylinder and passed out of the body. In addition, any larger parasites that happen to be in the stomach or digestive tract are "cut up" and killed by the sharp edges of the Diatomaceous Earth."
It also "is quite hard. On the hardness scale where diamonds are a 9, Diatomaceous Earth is a 7.
This is very important because as those millions of tiny hard and sharp Diatomaceous Earth cylinders pass through the small and large intestines, they "scrub" the walls.
After only a few months of taking Diatomaceous Earth, the intestine wall is no longer coated with mucus and molds but CLEAN!! The advantages of this are several:
-Maintains regular bowel movements
-Promotes a ealthier colon. This is especially important as we get older. A clean healthy colon keeps away polyps and ulcers. Today, many are spending thousands of dollars to get colonics when Diatomaceous Earth may do the same.
-Many users report increased energy and needing less sleep. This is a result of all the food and nutrients that are taken in being better absorbed into the blood stream. With a coated colon--many nutrients never get absorbed."
