What level of vitamin D is considered normal?

I recently had lab work done that identified a vitamin D deficiency. My level was eight and my doctor says that 30 is considered a normal level. I was then prescribed a vitamin D2 pill to help bring my levels up. I just read something that said vitamin D3 is the preferred type to use as a supplement and that 30 isn’t considered the “normal” level anymore, that the number should be closer to 40 or 50.

A few questions: Is it better to use D3 or D2? What level is considered normal? What are the effects of vitamin D deficiency?


How to help a friend who’s struggling with alcohol?

1) I have two friends who I think are drinking too much. I don't know what to do. They are very defensive should anyone say anything to them about their excessive habit, and a lot of our friends are giving up on them. This has become a daily thing and their schoolwork and friendships are all suffering. They are both 21; one recently broke up with his girlfriend of several years and the other has been single for a while and he hates it. I know that has a lot to do with it. Please suggest some non-intrusive ways to help them. I'm really at a loss.

2) Last year, I became very good friends with a guy on my floor. He was a little out of the ordinary in the way he dressed, as well as in some of his opinions and habits. I had the feeling that he did drink more than he should, and he also did pot. I did not worry too much about it because it appeared to be more of a lifestyle choice than an addiction, and it did not cause him major troubles.

Unfortunately, he started to have academic problems. He did not do his work, missed classes, and eventually exams as well. I still did not relate these things to his alcohol and drug habits, and I hoped that once he got over the adjustment everyone needed to make in freshman year, he would be fine. Well, he wasn't. He did not come back to school this fall, and when I called him, I learned that he had gone through a lot that summer. He was diagnosed with depression and a cocaine addiction, put on Prozac, and sent to therapy. At that point, I thought that he was on the right track because he was also going to get a job and planning to take classes at a nearby college.

However, when he came to visit me a month later, he had already had two beers before he even came here and got more and more drunk as the evening progressed. I would not let him drive home, but he ignored my warnings and left anyway. I was very disturbed because a friend of his had just been in a drunk driving accident. I was very mad at him, told him clearly that I will always be his friend but prefer not to talk to him or see him if he showed up drunk again. He did not call for a while and neither did I. When he called me yesterday and I told him that I thought he should do something about his alcohol problem, he kept repeating his excuses, that he drinks because he is Irish, that he doesn't care if he dies early as long as he had fun in life, etc. On the other hand, he can't find a job and seems to be very depressed. I want to help him, but I don't know how. Any ideas?


Does eating ice correct an iron deficiency?

My sister has been told by one doctor that eating ice is effective for an iron deficiency. Another doctor says that this is balderdash and not effective.

What is the deal? Which opinion is correct? Why is there no consensus on the feedback physicians give for this subject?

I also would like pointers to more information for this topic.

Thanks.


Why do people find fatty or sugary foods comforting?

Why do people find fatty or sugary foods comforting? I mean, what is it in these types of foods that causes the body / mind to see this type of food as comforting or pleasurable? Surely from the point of view of the body, it prefers foods that are high in nutrients — so why do people who turn to food for comfort always turn to fatty or sugary foods that don't offer the body anything? just wondering??? and I hope that made sense because I'm sorry it's quite badly worded!


Do diet sodas spike insulin levels?

I have heard that the main reason why diet drinks, like a diet soda, can be bad on a diet, is that it can spike insulin levels and then your body expects sugar that it does not get. I have taken to the habit of only occasionally having diet drinks with meals, so that any increase in insulin is actually met with food in my system. My question is whether or not this is a good/workable strategy, or whether a diet soda is a diet soda no matter when you drink it and is therefore always a bad idea. Thank you for your time.


Are there any nutritional benefits to swallowing semen?

1) I'm worried. What happens if you eat your own sperm?

2) Today a girlfriend and I were discussing the nutritional value of sperm. While performing oral sex, if you swallow, I was told that it is very high in protein. However, I was also informed that it is very high in calories. This may seem like a weird question, but I would like to know what nutritional benefits are involved when "swallowing" and how many approximate calories are in a man's ejaculation? Thank you for your help in this matter.
