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.

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?
