I think it life should be good for Vegetarians in zambia. This also should depend on what type of veg are you talking. Spinach? Always good for the health. Green chilies? Can cause many unpleasant problems or at times big explosions. So which type of veg are you talking about?
Being a vegetarian shouldnt cause you any problem unless you start campaigning against no-vegi and remember that the animal bones are used in making capsules(medications). Err.. there are no separate veg capsules.. imagine life of vegetarian without a capsule!!!
