Ask the Doc: AO2 Energy

AO2

Dear Doc: Me and the guys in my shop drink A LOT of caffeine. I'm not much of a coffee guy, but I do drink two or three energy drinks a day. I drink a lot of water too, and I'm young and in good shape, but sometimes I feel like I'm a little too reliant on these drinks. I sometimes short myself on sleep only because I know I can have an energy drink or two and be fine for most of the day. Is that a problem? Should I cut back? What are the impacts on my health? Are some forms of caffeine (coffee or tea, for example) better or safer than others? I'd rather focus on this while I'm young and healthy instead of keeping it up for a decade before I realize it's caused a real health problem. -AO2 Energy

Dear Doc: It seems like every time I go to the commissary, my daughter, 6, and son, 7, tend to gravitate toward the sugary cereals and frozen pizzas, and always want candy bars and sodas at the checkout. As far as I know, and as has been proven by their regularly scheduled check-ups, they are both in great health. The mother in me wants to give them what they want, but the former college athlete and current fitness freak in me is afraid that this might become a problem. For me, eating healthy has become a normal part of my life, and I've come to enjoy things that are healthy and taste good. Aside from tricking them, what can I do to get my kids to eat (and enjoy) more healthy foods? — Fitness Freaking Out
