A new study that was recently published online in Pharmacognosy Magazine highlights the brain-damaging capabilities of fluoride, and reveals that the curcumin found in Turmeric may combat the harmful effects that fluoride has on the brain.
The authors concluded;
“Our study thus demonstrate that daily single dose of 120 ppm F (Fluoride) result in highly significant increases in the LPO [lipid peroxidation, i.e. brain rancidity] as well as neurodegenerative changes in neuron cell bodies of selected hippocampal regions. Supplementation with curcumin significantly reduce the toxic effect of F to near normal level by augmenting the antioxidant defense through its scavenging property and provide an evidence of having therapeutic role against oxidative stress mediated neurodegeneration.”
Fluoride is added to many common products that we consume every day, including toothpaste and drinking water and is virtually impossible to avoid being exposed to. There is an ongoing controversy surrounding Fluoride and it stems from the harmful effects that overexposure to fluoride can cause, which include fluorosis, neurotoxicity and even cancer. The fact that it is routinely added to drinking water, which some believe amounts to being force-medicated without consent, is currently one of the the most hotly debated topics.
According to the authors, who have been studying the neurodegenerative effects that fluoride has on the mammalian brain for many years:
“Fluoride (F) is probably the first inorganic ion which drew attention of the scientific world for its toxic effects and now the F toxicity through drinking water is well-recognized as a global problem. Health effect reports on F exposure also include various cancers, adverse reproductive activities, cardiovascular, and neurological diseases.”
This particular study, which examined fluoride induced neurotoxicity, identified oxidative stress and over-stimulation of the neuron (referred to as excitoxicity) as two of the main causes of neurodegeneration in the brain. Previous observations of people suffering from fluorosis – a condition where the tooth enamel becomes discolored or mottled due to over-exposure to fluoride during the early developmental stages – also exhibit neurodegenerative changes that are associated with oxidative stress in the brain.
Previous studies conducted on the health benefits of curcumin have shown that it is a powerful antioxidant, that is able to protect the body against damage from singlet oxygen, hydroxyl radicals and superoxide radicals, and also boosts antioxidant defense mechanisms within the brain. The research team tested the neuro-protective properties of curcumin – a polyphenol agent present in turmeric – on mice, to see if it could potentially combat neurodegeneration and neurotoxicity associated with fluoride exposure.
The research team used a group of mice to both assess the neurotoxicity of fluoride and the protective benefits of curcumin in reducing these neurotoxicity effects. They divided the mice into four groups, which were kept separate for thirty days, as follows:
Group 1: no exposure to fluoride (control group).
Group 2: exposed to 120ppm fluoride in distilled drinking water that was freely available.
Group 3: exposed to 120ppm fluoride per 30mg/kg body weight in drinking water together with curcumin mixed with olive oil – dosage was administered orally.
Group 4: dosed with curcumin 30mg/kg body weight
After thirty days, the researchers measured oxidative stress levels in the brains of the mice. They found that mice in Group 2 that were exposed to fluoride only exhibited significantly higher levels of oxidative stress compared to mice in the Group 1 (control) who were not exposed to fluoride. The mice in Group 3 that were exposed to fluoride and curcumin exhibited lower levels of oxidative stress compared to the mice in Group two (fluoride only), which demonstrated the neuroprotective properties of curcumin against neurotoxity associated with fluoride exposure.
This is not the first study to highlight the health benefits of turmeric, a spice commonly used in Indian dishes. The paper cites over two hundred references to published scientific studies on the neuro-protective benefits of curcumin – an ingredient in turmeric – and there are thousands of articles on the GreenMedInfo database related to around 600 health benefits of curcumin and turmeric. Perhaps it's time to spice up your life.
