As I continue to try to get back into shape... and As I prep for my very long bicycle ride... I am thinking about trail mix today. Has anyone looked into what a good trail mix should contain? I am thinking about this from a health prospective, not a this tastes good prospective. Is there a benefit to having sunflower seeds vs. nuts or pineapple vs. ...? Is there a perfect pre-packaged trailmix? If not a perfect pre-packaged mix, what proportions make a perfect pre-packaged mix?
