Most Teas At Grocery Retailers Contain Toxic Levels of Fluoride

Drinking mixtures of cheaper tea found in major grocery stores can increase the level of fluoride intake of the population to toxic levels and put them at greater risk of skeletal and dental disease, a study by the University of Derby has found.

fluoride levels found in 38 tea products were compared with each other and with the Academy of Sciences National '(NAS) Dietary intake daily reference in the investigation of Laura Chan, professor Aradhana Mehra and Professor Paul Lynch of the University of Derby. The study is published in the journal Food Research International .

A previous study in the January 2005 issue of the Journal of American Medicine also found that instant teas appear to contain excessive levels of sodium fluoride. Green tea is one of the worst culprits having twice the amount of fluoride as black tea. brick tea has the highest concentration of fluoride and symptoms of fluorosis have been in Tibetan and adults who drink large amounts of this type of tea children.

tea plants fluoride accumulate in their leaves over time, so the older leaves contain most of fluoride, while the younger contain the least. Therefore, white tea (which is made from the youngest leaves and buds) is the best option to reduce exposure to fluoride.

Using the analysis of ion selective electrode (ISE) - that can analyze trace elements, such as fluoride, in a liquid - dry tea and tea infusions prepared with boiling water for two minutes, researchers compared levels of fluoride ingested by someone drinking the average daily intake of tea (four cups or one liter).

Significant differences in the levels of fluoride were discovered when the economy tea black mixture of supermarkets Asda, Tesco, Morrisons and Sainsbury were compared with black tea mixed with the brand as PG Tips, Twining of, Typhoo; and green tea blends including Clipper Organic leaf bags Green Twining; pure mixtures as Assam and Ceylon Dilmah; and mixtures Oolong and Pu'er of India and Sri Lanka.

found that infusions of black Economics tea blends, as Asda Smartprice, Tesco Value, Value Morrisons, Fundamentals of Sainsbury and essential Waitrose, have the highest concentration of fluoride - an average of six milligrams (mg) per liter. Although essential Waitrose was significantly lower compared with the black blends fluoride another economy.

Compared with the dietary intake of daily reference NAS four milligrams of fluoride per day, these mixtures containing tea economy from 75% to 120% of the recommended daily intake.

infusions of green tea mixtures had the following highest concentrations, followed by black mark mixtures such as PG Tips, Twining Typhoo and averaging 3.3 mg per liter, then pure mixtures.

Oolong and Pu'er tea had the lowest concentrations of fluoride -. An average of 0.7 mg / liter or ten percent only 16% of the Reference Daily Intake

Laura Chan, who conducted the study for her doctoral thesis at the University of Derby, said ". the tea plant, Camellia sinensis, is an accumulator of fluoride, with mature leaves accumulate most of the fluoride

" When the tea is harvested, the older leaves can be used to produce low quality, stronger teas and teas of the economy, while the yolk and newer upper leaves are used in the manufacture of products of higher quality and specialty tea.

In another study in caries Research (1996) 30: 88-92 fluoride content in tea with caffeine, decaffeinated and herbs, the average fluoride concentration of infusions prepared from decaffeinated (green and black) tea were found to be 3.19 ppm and ranged from 1.01 to 5.20. This was unexpectedly higher than tea with caffeine and this difference was statistically significant in this study. It is believed that this is due to the high content of fluoride in the water involved in the process of de-Caffeination, which then also would make decaf similarly high in fluoride.

In addition, caffeine in tea it has a great augmentative effect on the bioavailability of fluoride. In 1990, researchers at the University of Texas, although the theory that "the increased incidence of dental fluorosis in North America is mainly due to the replacement of water consumption for drinks containing caffeine in the youth population.

a very important from 1998 at the University of Nanchang in China study showed that in aged rats fed aqueous extract of green tea or green tea leaves, the calcium content in the new brain reduced significantly and the aluminum content increased. zinc content in the brain were also gradually decreased with increasing tea leaves and tea dose concentration. the brain is the part of the brain (frontal lobes) where thought and function highest reside.

the dental fluorosis, mottling of tooth enamel and bone fluorosis, pain and damage to bones and joints through calcification can occur through excessive ingestion of fluoride.

"People may be drinking excessive amounts of tea, and other power sources fluoride and do not realize these potential health consequences. In fact, there have been cases, both in the United Britain and the US, skeletal fluorosis in people who drank more than the average amount of tea economy. " Chan added Ms.

tea free of contaminant levels set by the Government

fluoride in tea is much higher than the maximum contaminant level ( MCL) set for fluoride in drinking water is 4 parts per million (ppm). About 50 percent fluoride (from any source) is deposited in the bones and teeth; the other half is excreted.

The MCL is set so as to prevent only the third and crippling stage of this disease. It was set at 4 ppm => 4 mg / liter, assuming that people will retain half of this amount (2 mg), and therefore be in a "safe" level. EPA scientists, whose work and the legal duty is to set the MCL, stated that this level was set fraudulently by outside forces, and is ignored that 90% of data showing the mutagenic properties of fluoride. chemical toxicologist and former EPA consultant Nancy Webert said "once the EPA began receiving funds from sources that are not disclosed to the public, studies of fluoride and safety limits took a back seat to other interests." Webert believes that the Government of the United States was fully aware of these foreign interests and did nothing to protect Americans from current levels of fluoride poisoning in drinking water.

How does the body fluoride?

Tea leaves more fluoride (from pollution of soil and air) edible any other plant accumulate. Coincidentally, the fluoride content in tea has risen dramatically with conconcurrently and world tea consumption in the last 20 years.

Drinking high levels of fluoride can cause the bone-forming cells to lay down additional skeletal tissue, which increases bone density. At the same time, it also increases bone fragility that can result in a disease known as skeletal fluorosis. So while the bones are more dense, they are also more fragile. skeletal fluorosis may occur:

bone, muscle and joint pain
Calcification of the ligaments
bone spurs
fused vertebrae
Difficulty moving joints

says Dr. Whyte, "When fluoride gets into your bones, it stays there for years, and there is no established treatment for skeletal fluorosis, it is not known if you can fully recover from it. " In other words, fluoride accumulates in your cuerpo.Según an estimate, the first phase of skeletal fluorosis could be easily developed in just five years, if a person were to consume the amount of fluoride found in three or four cups green every day tea.

While in 1976 a Belgian analysis showed content of between 50 and 125 ppm of fluoride in 15 varieties of tea, a study of Poland in 1995 found fluoride content up to 340 ppm in 16 varieties of black tea. A major Canadian study published in 1995 reported fluoride content in the average tea to be 4.57 mg / l in the early 1980.Prácticamente all companies selling green tea announces its high content of fluoride as "beneficial" in the caries prevention, the promulgation of misleading and false data from the last 50 years by the ADA / CDA and other professional dental health organizations and various public health agencies. There are no double-blind studies anywhere proving the effectiveness of fluoride as preventive caries. There are double-blind studies showing adverse health effects, both at the level of 1 ppm (1 mg / l) in water. There are no studies documenting safety at any level of consumption.

Drinking a cup of tea with fluoride content as mentioned above (7.8 mg) would mean fluoride intake much higher than the amounts actually were given as a medicine to treat hyperthyroidism (too much thyroid function) for many decades - in several countries -. specifically to reduce thyroid activity

to make things much worse for human health fluorides in teas are together with aluminum. The combination of aluminum and fluoride in tea is of urgent concern, due to increased damage caused by fluorides when in the presence of aluminum, especially neurological and kidney damage. It also increases the degree to which the aluminum can be absorbed by the body, which has been linked to Alzheimer's disease.

Aluminium by itself is not readily absorbed by the body, however, in the presence of fluoride ions, fluoride ions combine with aluminum to form aluminum fluoride, which is absorbed by the body. Aluminium eventually combined with oxygen to form aluminum oxide or alumina. Alumina is the aluminum compound found in the brains of Alzheimer's disease.

What can you do?

Stick to white tea has the fewer fluoride relationship. Encourage the purchase of more conventional organic tea. This does not mean that all organic teas will be absent fluoride, but farming methods are generally higher than conventional growers and some may even use purified water to the soil to grow their teas and herbs
