Hi all, I have a newbie question for you (I am an economist, and have nothing more than a novice's knowledge of basic nutrition, so apologies for my ignorance!). I am hoping one of you gurus can help me out. I am working with a database from a dietary survey. It lists grams of food consumed by individuals and for each food item, and also provides the total fat content per gram of the food, total saturated fat content, total mono and poly unsaturated fat content, etc. Problem is, it does not provide direct information on trans fat content per gram of the food, and I am interested in knowing this. Would it make sense for me to infer the trans fat content as: total fat - (saturated fat + monounsaturated + polyunsaturated)? Or is there some complication that blows this out of the water? I would much appreciate any insights. Thanks in advance.
