After practicing yoga in normal temperatures for years, I recently attended a heated yoga class (heated quite hot: 95 to 100 degrees!). The experience left me dizzy, nauseous, and completely enervated. Afterwards, I expressed my concern to the teacher, asking why the studio needed to be so hot. She "explained" that by sweating, supposedly the body releases "toxins" and that my nausea and dizziness must indicate that I need to "detox." Personally, I think I was suffering from heat exhaustion. I've heard this silly explanation more than once, as many people seem to believe toxins are released through sweat. But is that true??? And — next question — doesn't exerting oneself in extremely hot temperatures seem like a recipe for dehydration? Are their any benefits that make it worthwhile, or is all this heated yoga just nonsense?

I understand pomegranates are very good for you; being very high in antioxidants. How do you eat them? What about POM juice; is that just as good? How many ounces should I drink a day to be effective and yet not wasteful? Finally, pomegranate capsules bought in a health food store are much cheaper. Is a capsule a day just as effective?

First of all I would like to thank you for your work and help. Could you tell me, what is the significance of expensive food sensitivity tests based on IgG values? Most people receive a list of dozens of foods to eliminate from their diets without causing them any problems. I think it can lead to develop eating disorders or nutrient deficiencies. What do you think? Thank you so much for your opinion!

I don't really understand the way daily vitamin supplements work... I take One a Day for Women. My question is, if the vitamins you take are not time released, does your body use them the way intended or are they just a waste of time? Thanks.

Do you have information regarding decaffeinated coffee and its negative health impact? I have heard that the process used to produce decaffeinated coffee, or the ingredients thereof, do more harm than good.

My friend recently got a blood test back from her doctor and she was told she was deficient in Vitamin B12. She is a vegetarian. What can she do to supplement this vitamin if she does not eat meat?
