Effect of fluoride on the serum lipids of guinea pigs.

The effects of fluoride intake on the serum lipids of guinea pigs were determined in animals provided with either high or low levels of fat in their diet and fluoride in their drinking water. Evidence of the difference in fluoride intake were reflected by serum fluoride contents. The results suggest that, in guinea pigs receiving excess dietary cholesterol, an inadequate fluoride intake is reflected in increased serum cholesterol. Fluoride intake also influence the serum triglyceride levels, but the direction of the response was dependent on the amount of dietary fat. Serum free fatty acids and phospholipids were not influenced by fluoride intake.
