Have you ever done a detailed analysis of your food intake?
For my Kinesiology class, we were given a program called evaluEat, and the assignment is to enter absolutely everything we eat and drink each day for 5 days. The program provides an analysis of the information, letting us know what elements we are short on, and what elements we are consuming too much of, given a certain activity level.
So far, I'm having a little bit of trouble getting the program working ... it doesn't seem to like the fact that I eat so many different things in a day, and do so many different things in a day ... but it will be interesting to see what the results are.
However, in preparation to use that program, I wrote down everything I've eaten and drunk over the past 3 days and it is quite interesting ... I snack a tremendous amount. Basically, I eat one actual meal each day, and the rest of the day is spent grazing. I'm not sure if that's a good thing or not.
I would really recommend writing down everything you eat over a few days ... it really is quite revealing!
