Q: Does a junk food diet increase the risk of getting injured while playing sports (muscle strain for example)? I've pulled my calf muscle twice in three weeks while playing badminton.

A: It's unlikely that junk food can cause immediate physical injuries. It's certainly bad for you and in the long run will cause all sorts of problems, but having a poor diet for just a couple of weeks shouldn't lead to injuries. However, what can happen is that injuries will take longer to heal if your diet is lacking in nutrients. Muscle cramps become more likely as well.
