Also spotted via Twitter, my main (only?) connection to the external world since I never pay any attention to current affairs, this article about Lipton in the US getting warned off by the FDA for making tea-related health claims. It is simultaneously funny and depressing to see companies claiming that their highly processed, sugar-filled, RTD teas are 'good for you' - come on, it's non-fizzy soft drink, people!
Plus it appears that the antioxidants in tea degrade over time, so fresh is going to be better than bottled - but we knew that anyway!
Finally, I boggled when I read this here:
Tea is generally considered to be safe, even in large amounts. However, two cases of hypokalemia (abnormally low serum potassium levels) in the elderly have been attributed to excessive consumption of black and oolong tea (3-14 liters/day).
To be honest, I think that anyone who was drinking that much (14 LITRES? How could you manage it?) of anything might end up just a little bit potassium deficient...
