|If I remember correctly, you are studying to become a trainer or something?? In any regard, you seem to know a lot about nutrition. I'm hoping you can refer me to a book that discusses some key nutritional concepts in laymens terms. I'd like to learn the difference between simple and complex carbohydrates and the various types of fats, cholesterols, etc... and the affects of these on the body.

|my advice to you, should you decide to accept it, is that trying to understand this stuff is a waste of time. Not because you are unworthy or the subject is unworthy, but because people are complicated and this stuff is so imperfectly understood. |
So much of what's written is about untested or partially tested theories extrapolated wildly from scraps of data of varying reliability that I can't imagine that it is worthy of a layperson's study. The theories constantly evolve to the point where trying to follow it, unless you are an expert yourself and can guage its worth, will lead you down many false paths. Eggs are bad. Eggs are good. Carbo's are great. Carbo's are bad. Protien is bad. Protien is best. Shrimp is loaded with cholesterol. Yeah, but it's the good cholesterol. Etc., etc. What happens in the lab is such a far cry from what happens in a living, adaptable, hormone-adjusting, responsive human being that it is very nearly worthless, in my opinion, as a guide for your life. When you see the striving for academic recognition as well as the incentive to capitalize on partial theories, you understand better how this data, such as it is, makes it into the mainstream, but it doesn't make any more worthwhile.
Think about it, anyway. My own belief is that people are omniverous and have developed to eat what is available when it is available. So, a mixed diet is best. Everything in moderation. Maybe we should skip the 22 oz. porterhouse, but a bit of beef every now and then seems entirely consistent with our natural history. Etc., etc.
As far as I can tell, the people who are physically successful (maybe not top athletes, whose nutritionists need to justify their existence, but people who live to be 120, that sort), are zealous about absolutely nothing except their moderation.

|And I am definately not standing in line to become a food zealot...unless, of course, you mean one who zealously eats rich, comfort foods. What I am mostly wondering these days are good basic questions. Which kind of rice should I buy. Brown rice? White? Long grain? What does enriched mean. Same for egg noodles and bread. Basic stuff that is tried and proven, etc... I don't care what anyone says about eggs. My take: God made chickens and chickens lay eggs. They taste good and don't send me to the hospital. Therefore they are food.|

|Kristen, there are very simple things to consider. Keep the concepts simple and you'll be ok. Firstly, in regards to carbohydrates, there are simple sugars and complex carbohydrates, etc. Basically, any white pasta or white bread, regular rice is a simple sugar. Long grain doesn't have anything to do with nutrition. Wheat products, especially multi grain, unrefined grains, get into the complex carbohydrate realm. The difference between the two is the speed they can be utilized for fuel by the body, or turned into fat.
For laymen, some simple things to consider. Eat a variety of foods. Lots of resh fruits and vegetables. Should you have pastas, rice or breads, go for brown rice, spinach type pastas, multi grain breads. Reduce your amount of oil intake, reduce saturated fats. Increase your fiber intake, oatmeal and fruits are very fiberous.
Try reduced fat cheese if you eat it, egg substitues, less yolks if you use the real thing, try Benecol. If you eat fast food, forget the fries and sauces and stick with the grilled or broiled chicken breast sandwiches.

|I have a lot of books on nutrition, but most of them are textbooks and studies and aren't real user friendly in their writing style Kristin. Talking energy metabolism and it's effects on exercise sort of stuff, they make my brain hurt just thinking about them. I'll ask a nutritionist friend what they think for good laymen's terms books and get back to you. Sorry I don't have a lot to offer here. The only thing I might be able to suggest is to go to a local college and see what they use as a text in their intro to nutrition class. Usually those texts are pretty easy reads, and don't embrace radical, unproven ideas.
I'll get back to you on this one. Sorry I don' t have more for you now.

|the easiest way to explain the difference between complex and simple carbs is how large the molecule of carbohydrate. a complex carb has more carbons than a simple carb...what this means is that the complex carb takes longer to digest and makes you feel fuller longer where as a simple carb is digested easily and absorbed alot quicker. both have their advantages and disadvantages.
As fat as fats go there are many differnt kinds.
I assume you want to know the difference between saturated, unsaturated and poly unsaturated...well here is goes
saturated fats are the worst to eat and poly unsaturated are better to eat...and unsaturated fall in the middle of the two. the reason why they are saturated unsaturated and poly unsaturated has to do with the chemical structure of the molecule (not of too much importance to you) I could probably write a lot about the differnt kinds of fats but ill save it for later if you really wanna know =)
as far as cholesterol there are 2 kinds.High density and low density cholesterol...i think the abbreviations are HDLV(high density) LDLV(Low density) I could be wrong...for some reason I am having trouble remembering the correct abreviations. there are studies that show that the HD is benefical for the blood and the LD is what clogs the arteries....the bottom line with cholesterol though is the less you have the better =)
I know this is very vauge but i tried to make it short and sweet...if anyone has questions i posted my email
