Abstract
Radish (Raphunus sativa), coriander (Coriandrum sativum), mustard (Brassica juncea), and spinach (Spinacea oleracea) plants were grown in earthen pots watered with aqueous solutions containing 0, 5, and 10 mg F/L. Fluoride (F) uptake and superoxide dismutase (SOD) activity (unit/mg protein/min) were estimated from the edible plant parts following harvest after 60 days. The values of
both entities rose with increasing F exposure in the order radish > coriander > spinach > mustard. The results indicate that plant species tolerant to F toxicity induce higher antioxidant SOD activity, which may be an adaptive reaction in plant cells to attenuate the damaging effect of reactive oxygen species (ROS) generated during F stress.

Glycine alleviates fluoride-induced oxidative stress, apoptosis and senescence in a porcine testicular Sertoli cell line.
Glycine is a well-known free radical scavenger in the cellular antioxidant system that prevents oxidative damage and apoptosis. Excessive fluoride exposure is associated with multiple types of cellular damage in humans and animals. The objective of the present study was to investigate the protective effects of glycine on sodium fluoride

Fluoride induced tissue hypercalcemia, IL-17 mediated inflammation and apoptosis lead to cardiomyopathy: ultrastructural and biochemical findings.
An increased prevalence of cardiac complications has been observed in residents of fluorosis endemic areas chronically exposed to fluoride. Fluoride induces soft tissue injury due to oxidative stress, lipid peroxidation (LPO) and mitochondriopathy. It was hypothesized that chronic fluoride exposure induces apoptosis in cardiomyocytes due to inflammation, lysis of extra

Epigallocatechin gallate supplementation protects against renal injury induced by fluoride intoxication in rats: Role of Nrf2/HO-1 signaling
Fluoride intoxication generates free radicals, causing oxidative stress that plays a critical role in the progression of nephropathy. In the present study, we hypothesized that epigallocatechin gallate (EGCG), found in green tea, protects the kidneys of rats treated with fluoride by preventing oxidative stress, inflammation, and apoptosis. Pretreatment of fluoride-treated

Fluoride in Drinking Water and Skeletal Fluorosis: a Review of the Global Impact.
When safe and adequate exposure of an essential trace element is exceeded it becomes potentially toxic. Fluoride is one classic example of such a double edged sword which both plays a fundamental role in the normal growth and development of the body for example the consumption of levels between 0.5–1.0 ppm

Environmental and Genetic Factors Influencing Kidney Toxicity.
The kidneys are a frequent target organ for toxicity from exposures to various environmental chemicals and agents. To understand the risk to human health from such exposures, it is important to consider both the underlying chemical and pathologic mechanisms and factors that may modify susceptibility to injury. Choices of exemplary

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,

Fluoride & Oxidative Stress
A vast body of research demonstrates that fluoride exposure increases oxidative stress. Based on this research, it is believed that fluoride-induced oxidative stress is a key mechanism underlying the various toxic effects associated with fluoride exposure. It is also well established that fluoride's toxic effects can be ameliorated by exposure
