I got this question at work the other day (we’re a fairly healthy-minded bunch):
What are complex carbs vs simple carbs?
This question seems complex, but the answer is quite simple. Simple carbs and complex carbs end up in the same place of the nutrition facts label, but they are most certainly different.
Are all carbs bad?
Clearly not all carbohydrates are bad. We need carbs to live – glucose (what carbs break down to in your body) is what your body uses for energy. That’s why when you eat a candy bar you get hyper for a little while – your body just got a big dose of easy-to-use energy because the carbs were partially processed before they got to your stomach. Simple carbs and complex carbs both turn into sugar in the body; the process just happens faster for simple carbs.

I watched 3 really interesting videos in the last 3 days. The first was a documentary on Hulu called Fat Head. Here’s the summary:
Have you seen the news stories about the obesity epidemic? Did you see Super Size Me? Then guess what? … You’ve been fed a load of bologna.
Comedian (and former health writer) Tom Naughton replies to the blame-McDonald’s crowd by losing weight on a fat-laden fast-food diet while demonstrating that nearly everything we’ve been told about obesity and healthy eating is wrong. Along with some delicious parody of Super Size Me, Naughton serves up plenty of no-bologna facts that will stun most viewers, such as: The obesity “epidemic” has been wildly exaggerated by the CDC. People the government classifies as “overweight” have longer lifespans than people classified as “normal weight.” Having low cholesterol is unhealthy. Lowfat diets can lead to depression and type II diabetes. Saturated fat doesn’t cause heart disease — but sugars, starches and processed vegetable oils do.

How much protein do I really need?
::Steps onto soapbox::
The current accepted answer (in the medical community) is .8 grams per kilogram of body weight. This is what I learned in my nutrition class (from a PhD in nutrition). This means that a 125 pound woman needs about 45 grams of protein a day. This is actually down from many outdated recommendations.
Want to hear something crazy? That number might be overestimating.
I saw my brother about a week ago and he is STRONG. Rob is a vegetarian and has been for probably 7 or 8 years now (he’s 20). Rob is 6’4″ and close to 200 pounds, but he wears the same size shirt as my 6’1″ 165-170 pound fiance (hope they don’t mind me telling their weights, heh – and the shirt size is a men’s medium).
