1) Which foods, if any, have negative calories?

2) I have recently started a weight loss plan and after doing some research I learned about calorie burning foods. My question is, are there really calorie burning foods or is it just another diet fad?

I have been a lacto-ovo vegetarian for three years now. I want to stop and get back to eating meat. I do not know the proper way of doing this, so I would love feedback on how to plan my meals.

I eat lots of different kinds of lentils but don't know much about their individual nutritional properties. Are certain kinds of lentils healthier than others? What are the different calorie and protein figures for different kinds of lentils?

Is milk good or bad for you?

I read on someone's blog about drinking seltzer water if you're trying to quit drinking soft drinks but still need that fizz. Are there any good/bad side effects to drinking seltzer water?

I have a question about dehydration. I am an eighteen-year-old female and play on a varsity basketball team. We usually have two-hour practices in which we work very hard. Our coach does not give us water breaks, and usually by the end of practice, we have cottonmouth and are "dying" for water. It is horrible. Is there any way that not having water during that time can be dangerous? Sometimes the team can feel sick or weak by the end of a practice.

Do dried blueberries have the same health benefits as fresh blueberries?

I have a job that is largely sedentary — mostly sitting in an office in front of a computer. My partner's work is very physically active. Since we've been living together, food and nutrition have increasingly become a source of stress and conflict. He needs big meals with lots of protein and calories, and I need better portion control with lots of vegetables. We're having real problems with shopping and menu planning. Since we've been living together, I've been gaining weight and he's been losing! Can you give us any advice or direct us to information on how to live and eat together while addressing both of our nutritional needs?
