Can supplements affect birth control effectiveness?

1) Is it true that taking those Emergen-C packets or any other vitamin supplements can effect the effectiveness of your birth control pill?

2) I know antibiotics can lower the effectiveness of birth control, but can probiotics or prebiotics, such as a floral acidophilus FOS, also decrease effectiveness? I've been taking birth control pills for the past 10 years with no scares or baby bumps, and I don't want to wake up pregnant one day because I took a capsule that's supposed to be healthy! :)

How can I support a friend with mental health concerns when I’m struggling myself?

1) This is more of a coping question. I am a first-year who applied for a single room over the summer and was denied. I figured that everything would be okay nevertheless. I tried to look at the situation as a character-builder. Well, that is not the case. My roommate is very depressed. I talked to the RA on my floor, but she didn't take any action, except to talk with her. Unfortunately, my roommate is so ashamed of what's happening that she denied the facts, and the RA believed her. No one except me has realized yet that she is sleeping most of the day and all of the night, and that it is indeed a real problem. I have expressed my concern to her and encouraged her to go to counseling services. She went a couple of times and then started canceling appointments left and right. I have worried about her, but I have no backup whatsoever, so there is really nothing I can do to help at this point. We get along relatively well otherwise.

Right now, the concern I have is that her depression is pulling me down, too. I literally have not been alone anywhere for more than two to three minutes in weeks. I wanted a single because it's a requirement that I spend some time by myself, and I'm going crazy these days. The lights are always out in the room, and I've noticed that I'm sleeping more than usual myself as the situation has progressed. Also, I am having to deal with some personal issues of my own this semester, and I simply don't have the energy to take care of someone else who desperately wishes that I would do so. Any ideas would be greatly appreciated.

2) I know that when a friend is depressed, it's important to reach out, discuss the issue, and be there for the person as much as possible. But that's quite hard to do when I myself have a history with depression — I feel as if her emotions are taking me back to a place that I don't want to go. I really empathize with my friend and feel her pain, but at the same time know that I'd be useless to both of us if I'm in the troughs too. How can I help without sacrificing my always precarious emotional equilibrium?

Am I the right BMI and weight for my height?

1) A friend and I were discussing this. We both try to stay healthy by eating well (high fiber, low fat, lots of veggies, fruit, etc.) and living an active enough lifestyle (hiking, rock climbing, biking, etc.) that we stay in shape. The question we have, then, is what the current "rules" are for appropriate weight/height ratios? Or are such measurements now thrown out in favor of body fat percentage measurements? She's 5'1" and I'm 6'1" and we're curious what the medical rule of thumb would be for how much each of us "should" weigh...mostly because we're wondering if it takes into account things like muscle mass. What would the current medical/health industry recommend each of us weigh? Are these numbers accepted or are they seen as not as important as they might have been 20 years ago. If you have actual numbers, we'd be curious to see that too. Thanks! I have a dinner riding on this!

2) Could you clarify the Body Mass Index deal? According to one BMI chart, I am "slightly overweight" because I am 5' 5-1/2" tall and weigh 160 lb. I am also very muscular and have a large frame. The lower BMI readings are labeled "ideal," but I've heard muscle weighs more than fat, so if the chart does not include the muscle factor, is it basically saying that it's "ideal" NOT to have extra muscle? I look slender and have never been told by a doctor to lose weight. I'm a twenty-four-year-old female, lacto-ovo-vegetarian, and get lots of exercise, including walking and frequent "sweaty" workouts.

Should I be concerned about BPA from hard plastic water bottles?

I use Nalgene bottles for about 75 percent of the water I drink each day. Therefore, I was startled to find out that there is some possibility that these bottles leach chemicals into the water. I've found conflicting opinions about the veracity of these claims on the Internet. What's the truth? Should I dump my Nalgene for glass? You have an earlier post about bottled water, but it doesn't seem to address this issue specifically, and you recommend purchasing reusable bottles like the ones that might be poisoning me. The bottles I use have #7 on the bottom in the recycle symbol.

Does sweating release toxins?

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?

Are overcooked pasta and beans still nutritious?

I know if I cook vegetables too long, they would lose nutrients. How about pasta and beans? Do they lose their carbohydrates and proteins and other nutrients in them if I cook too long? I always cook pasta and beans for over an hour because I like nice and soft and plumed pastas and beans. Am I eating zero nutritious pasta and beans?
