I converted over to tea a few years ago, it is much better for studying – a calmer stimulation whereas coffee tends to make you want to go out and party, whereas you need calm patience for the endless boredom of studying.
The problem is I recently heard an interview with an expert on Fluoride. Fluoride is toxic and a strong pharmacological agent. they used to use it to control hyperthyroidism 6 – 10 mg/day, since it particularly affects the thyriod – perhaps by antagonizing Iodide, and maybe by damaging iodide receptors since it apparently is cytotoxic.
Green or black tea has naturally high fluoride, it is one of the very few plants that absorb it from the soil. they think it might be to deter animals from eating it since it makes them nauseous. I have gotten nauseous from drinking black tea without milk, I thought it was the bitter antioxidants like catechins but maybe not.
Anyway natural Fluoride is not as bad as the industrial sludge they put in our drinking water which is not NaF but hydro-fluoro-salicylic acid plus other toxins like arsenic 1 ppb. Acc to Dr Kennedy the US EPA (scientific advisory branch of the US govt) found 0.2 ppm in drinking water harmful to infants (US govt rec’s 10X that in drinking water). A cup of Lipton’s ice tea was found to have 8 ppm (or about 2 mg).
So everything was turned on its head for me a few days ago with this talk – shouldn’t just rely on one talk so I’ll be checking up – might even do my masters thesis on it. But he seemed very credible, a dentist with a degree in comparative biochem and physiology. it might turn out that the natural F is not too bad… but I doubt it. Fluoride is apparently also put in all sorts of medical drugs as a potent physiological activator – another reason to avoid the medical crap.
Sorry to throw a wrench in the works… it threw me off quite severely, but that’s nutrition…
I have a slight addiction to caffeine – need one cup a day to avoid headaches and malaise – so will divide it between yerba mate and coffee until I find out more. A box of Lipton’s has already gone in the garbage.
