Going into school this year, I am going to bring a sack lunch. I was wondering what I should bring that would be healthy and not take a lot of preparation time?

Most of my friends and I often eat out for many of our meals. What are the effects of this trend on health?

I've been taking a daily supplement of 400 IUs of vitamin E. I recently bought a bottle of 1000 IUs, and a friend told me that that's too much to take, and could even be bad for me. Is that true?

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!

1) Is it true that eating fat keeps the body warm in cold weather?

2) What I'd like to know is, does my body burn more calories to keep me warm when it's cold out? Thanks!
