Abstract

Fluorosis is a major health problem in many parts of the world. The present work focuses on investigating the utility of nutrient and antioxidant rich grains- ragi, jowar, bajra, maize in formulation of basal, high carbohydrate low protein and low carbohydrate high protein diets in mitigating fluoride toxicity. Exposure to fluoride through drinking water not only significantly increased plasma glucose and lipid profiles, but also elevated both hepatic and renal lipid peroxidation, hepatic lipid profiles and G-6-Pase activity with a reduction in plasma HDL-C, hepatic glycogen content, hexokinase activity and antioxidant status. Even though basal and high carbohydrate diets did not significantly alter plasma glucose, lipid profiles in fluoride administered animals, protein enriched multigrain diet significantly decreased plasma glucose and lipid levels. However, the multigrain basal and high carbohydrate diets influenced the hepatic glycogen, lipid profiles, hexokinase and G-6-Pase activities, hepatic and renal lipid peroxidation and antioxidant status though not as significantly as that of multigrain diet enriched with protein. Thus the results of the present study indicate that both a multigrain diet rich in nutrients and antioxidants, and fortified with protein is useful in mitigating the fluoride toxicity.

    OBJECTIVES:  Fluoride is a serious health hazard across several nations, and chronic intake of fluoride deranges the carbohydrate, lipid and antioxidant metabolism in general. As there are limited remedial measures to prevent fluorosis, we investigated the role of tamarind leaf as a food supplement in restoration of carbohydrate, lipid and

  • Nutrient Deficiencies Enhance Fluoride Toxicity

    It has been known since the 1930s that poor nutrition enhances the toxicity of fluoride. As discussed below, nutrient deficiencies have been specifically linked to increased susceptibility to fluoride-induced tooth damage (dental fluorosis), bone damage (osteomalacia), neurotoxicity (reduced intelligence), and mutagenicity. The nutrients of primary importance appear to be calcium,

    In the 1960s and 1970s, doctors discovered that patients receiving kidney dialysis were accumulating very high levels of fluoride in their bones and blood, and that this exposure was associated with severe forms of osteomalacia, a bone-softening disease that leads to weak bones and often excruciating bone pain. Based on

  • Mayo Clinic: Fluoridation & Bone Disease in Renal Patients

    The available evidence suggests that some patients wtih long-term renal failure are being affected by drinking water with as little as 2 ppm fluoride. The finding of adverse effects in patients drinking water with 2 ppm of fluoride suggests that a few similar cases may be found in patients imbibing 1 ppm, especially if large volumes are consumed, or in heavy tea drinkers. The finding of adverse effects in patients drinking water with 2 ppm of fluoride suggests that a few similar cases may be found in patients imbibing 1 ppm, especially if large volumes are consumed, or in heavy tea drinkers and if fluoride is indeed the cause. It would seem prudent, therefore, to monitor the fluoride intake of patients with renal failure living in high fluoride areas.
