Awesome. My daughter did the same...I think Lamb kicked it off for her. I did get a supplement (can't remember which) and explained to her that being veg isn't just about cutting out meat, that she had to increase her nuts, legumes etc.

She went on and off for a few years (ok with me) and now at 18 she eats minimal meat (sometimes she craves it a little), no dairy and is very aware of how foods affect her body.

I eat little to no meat at all myself for the same reasons as Nai.
