Diatomaceous Earth (Food Grade)

What It Is

Diatomaceous Earth (often abbreviated as DE) is a naturally occurring, soft, siliceous sedimentary rock that crumbles easily into a fine white or off-white powder. It is made up mostly of fossilized remains of diatoms, which are tiny aquatic organisms with silica-based shells. Over time, these shells accumulated in riverbeds and oceans, forming rich deposits of silica.

There are two main types of DE:

• Food grade, which is purified and safe for human and animal consumption.
• Filter grade (or industrial grade), which is heat-treated and used in manufacturing or filtration, but not safe to ingest.

When used in a health context, only food grade diatomaceous earth should ever be used.

How It Works

Diatomaceous Earth is composed primarily of amorphous silica, a mineral that plays an important role in bone, hair, nail, and connective tissue health. It is believed to work in two main ways:

1. Mechanical Action (Physical Cleansing). The microscopic particles of DE have sharp edges at the microscopic level. When ingested, these particles may help scrub the digestive tract, binding to toxins, heavy metals, and waste material, and carrying them out of the body through the intestines. This makes DE popular among those using it as a natural detoxifying agent.
2. Absorptive Properties. DE has a high surface area and is extremely porous, allowing it to absorb moisture, oils, and unwanted compounds. This helps reduce intestinal parasites in animals and may support internal cleansing in humans.
3. Silica Support. Silica, the main component of DE, is a trace mineral that contributes to the maintenance of skin elasticity, joint flexibility, bone strength, and healthy hair and nails. Some proponents believe that DE supplementation supports the natural replenishment of silica in the body, which tends to decrease with age.

Why It’s Important

From a health standpoint, food grade DE is valued for several potential benefits, though many are anecdotal or based on preliminary studies rather than large-scale clinical evidence. Reported benefits include:

• Digestive Health: It may support regular bowel movements and help clear the digestive system of waste buildup.
• Detoxification: DE is thought to bind to and remove harmful substances such as heavy metals, bacteria, and other impurities.
• Joint and Bone Health: The silica content may contribute to collagen formation, bone density, and joint flexibility.
• Hair, Skin, and Nail Health: Silica helps maintain the strength and appearance of hair and nails while supporting skin elasticity.
• Pest Control (Indirect Human Benefit): Although not directly a health use, DE is often used as a non-toxic way to control insects in the home or around food, reducing exposure to chemical pesticides.

While some of these claims are supported by biological plausibility, scientific validation is still limited, so DE should be approached as a supplement to a balanced diet and not as a medical treatment.

Considerations

Before using Diatomaceous Earth for health purposes, several important factors should be understood:

Quality and Purity. Only food grade DE should be used for internal or personal use. Industrial or pool-grade DE contains crystalline silica, which is hazardous when inhaled or ingested. Always verify purity from reputable sources.

Dosage and Usage. There is no universally established dosage, but most natural health practitioners recommend starting with small amounts (e.g., ½ teaspoon per day mixed in water) and gradually increasing as tolerated. DE should be taken with plenty of water to prevent dehydration or constipation.

Possible Side Effects

• Mild Digestive Upset: Some individuals may experience temporary bloating, constipation, or discomfort as the body adjusts.
• Inhalation Risk: The fine powder can irritate the lungs if inhaled. It should be handled gently to minimize dust.
• Silica Overload (rare): Excessive long-term intake could affect kidney health, though this is uncommon with moderate use of food-grade DE.

Scientific Limitations: While anecdotal evidence is widespread, rigorous scientific research on the internal use of DE in humans remains limited. Its effectiveness for detoxification or parasite control has not been conclusively proven through clinical trials.

Consultation with a Professional: Individuals with respiratory issues, gastrointestinal disorders, or kidney disease should consult a healthcare provider before use. DE may interact with certain medications or supplements.
