I have only been studying kung fu for about a year and a half, and became vegetarian about a year ago. My flexibility was horrendous starting out, my elbow being about two feet from my foot when trying to do "elbow to toe" exercises. After a few weeks of being vegetarian, I noticed rapid improvements in flexibility, and within a few months was routinely getting my elbow to my toe, with correct posture (in case anyone was wondering).

Now, this may be simply a correlation, as a high vegetable diet does wonders for my mental health and dedication to the art of kung fu. However, I recently compromised my ethics to eat a sizeable chunk of ham (drinking was involved). For the next few days, my flexibility was significantly lessened. Maybe it was just cold.

Does anyone have personal experience regarding this possible connection?
