- Pest Control: Employed in some pesticides.
Ingestion of sodium fluoride can occur from several sources, including drinking water, dental products, and food.
The Role of Sodium Fluoride in Food
Sodium fluoride doesn’t actively participate in food preparation or processing; instead, its presence primarily results from environmental factors. Fluoride can accumulate in the soil and water, impacting the crops grown in these areas. Additionally, animal products may contain sodium fluoride if animals have been exposed to fluoridated water.
How Foods Accumulate Sodium Fluoride
Sodium fluoride can enter the food chain through various avenues, with the following being the most significant:
1. Water Supply
When public water systems are fluoridated to improve public health, the fluoride can be absorbed by the crops grown using this water. This absorption can lead to increased fluoride levels in fruits and vegetables.
2. Soil Contamination
Fluoride naturally occurs in soil. Certain soils contain higher levels of fluoride due to geological conditions, which can lead to the absorption of fluoride by plants. Crops planted in such soils may contain elevated levels of sodium fluoride.
3. Livestock and Animal Products
Animals raised on fluoridated water or fluoride-contaminated feed can accumulate fluoride in their bodies. Thus, meats, dairy, and eggs from such livestock may inherit sodium fluoride residues.
Foods That May Contain Sodium Fluoride
Certain food categories are more likely to contain sodium fluoride due to the reasons stated above. Here, we explore these categories in detail.
1. Fruits and Vegetables
Fruits and vegetables can absorb sodium fluoride from fluoridated water and fluoride-rich soil. Here are some examples:
