How to read and trust nutrient value charts?

I have researched health and nutrition online for a while now, and I work out not only with weights and yoga, but martial arts and mountain biking, as well.

Lately while researching online, I've found that a lot of nutritional value charts conflict in numbers. Some charts say that skim milk contains eight grams of protein, some charts say skim milk contains 13 grams of protein. Which charts are right?? This is incredibly frustrating and confusing. I did find out that there is nutrition software available, but it's so expensive and it comes with lots of extra things that only doctors need really, like making charts for patients and what not.

Also, I found information on one site saying that adults should consume 0.8 grams of protein per however many kilos you weigh (I weigh 82 kilos, so that means 66 grams of proteins per day). Another site said that adult females between 25 to 50 kilos just need 55 grams of proteins per day. Also, it's not just protein intake that conflicts with all of these charts online.

If you can help out at all, it would be greatly appreciated. Thank you in advance.


Can I decrease the amount of sleep I need?

Is there any way that I can reduce the amount of sleep I need voluntarily? Right now, I need a lot of sleep (ten hours or more) and I would like to reduce this so that I can sleep healthily for eight hours a night. Is this possible, given the way that my body works? I have heard that it is, that I can "train" my body to require less sleep. It certainly isn't healthy to sleep fewer than eight hours if my body needs ten, of course. And I'm sure that some people are forced to sleep for six or fewer hours a night for years! Do their bodies just adapt?


Am I ready to start dating a new guy?

I have recently started seeing this man who I think is adorable and things are going really well. My last relationship was a three year nightmare that ended a long time before I finally broke it off. Everyone keeps saying to follow the rules and take it slow and to be careful because I am on the rebound and it is too soon to get involved. How can I know if what I am feeling is right and if I should just go with the flow? I am still feeling so new at all this stuff and I am often very scared to get hurt again. Please give me some of your expert advice!


How can I help loved ones who have bulimia?

1) I've recently just found out that my boyfriend of four years is bulimic... He hasn't told me, but I have put the puzzle pieces together after living with him for the past 18 months... I had even heard him purging in the bathroom while we were on vacation. I'm really struggling with this information and I don't know how to approach him about it... I'm guessing it has been going on for around six years now. How do I confront him about it??

2) I was wondering if bulimics lose weight rapidly, because I have a friend who I think may be bulimic, because she eats, but I think she may be throwing up her food. She has lost 25 pounds in the last month. She binges, and I would like to know how I can help her.


What can I do about my dry skin?

Please help! My skin is drying out like you would never believe. It is scaly and itchy at times. Could this be as a result of the weather? Are there any pointers that you could give me so that I don't feel like my face is cracking and looking like garbage? It seems to get worse after I shower. What is this? What can I do?


Can I donate a kidney to my friend?

I just found out that a friend requires a kidney transplant. I've heard that we are all equipped with two kidneys and can live with just one. How do I find out if I can donate a kidney? What's involved in a kidney donation? Thanks!


Is Mirena safe for those who have yet to give birth?

I have recently been advised that my on-going migraines might be caused and/or increased by the use of contraceptives containing estrogen. To that end, I have been recommended to switch to a progesterone-only form of birth control. Which, in turn, basically means I get to choose between Implanon and Mirena (I really can't stand needles, so Depo is out for me!). I am only 23 years old, and have not yet started a family. I do want to have children someday, and am very enticed by the idea of Mirena lasting to the point when I might want to begin trying to get pregnant. However, all of the advertisements for Mirena state that ideal candidates have already had children.

Is Mirena still safe for use in women who have not yet given birth? If so are there any additional side effects to consider in this instance?


What should I do if I'm successful but not happy?

I'm not in college anymore, but students could benefit from this question, too. I'm single with a 'great' job (pays well, insurance, pension, etc.), a decent place to live, no debt... in short, life could be much worse. But the only thing lately that makes me happy is doing kind things anonymously for people. I'm rather wealthy but don't want a big TV or a fancy car. I'd rather spend a vacation at a local monastery meditating and performing service. I'd be committing economic suicide to quit my job, and so many are worse off, but 'success through hard work' doesn't make me happy. I'm sure a number of students must have these feelings already. What are your feelings about this, Alice?


Can I preserve my fertility?

I've heard so many horror stories of women who wait until their mid-thirties or later to have children, then find out that they are infertile. I'm 25 years old now and nowhere near getting married or having babies, yet I don't want this to happen to me when I'm ready. What can I do now to protect my fertility and make sure I am able to conceive when the time is right? It's causing me a lot of anxiety!!
