When is the right time to educate your children on the benefits of veganism?

My wife and I want to raise our daughter to be a strong, independent, healthy, and intelligent woman.  We don’t want to force anything on her just because we want her to be a certain way as that defeats the entire purpose, so I am wondering when is the best time to truly educate her on the benefits of veganism?  I say “best time” because obviously as an infant and toddler we can dictate what foods she consumes as well as when she starts and progresses through the early stages of daycare and school.  What happens though when other kids start talking about their lunches, or when she really begins to think independently and stay with friends, or have sleepovers, and maybe even goes to sleep away camps?  How can we best prepare her?  I think that question mostly answers itself right?  The path forward starts early as you raise them to enjoy the food that you eat yourself and I think just the subtle continuing of education helps to set your child up with a solid foundation.  The basis for this post was I think the majority of people become vegan after watching “X” documentary, whether that be Cowspiracy, What the Health, Forks Over Knives, Earthlings, Live and Let Live or the numerous other powerful films many of which may not be appropriate for kids to see at certain ages.  I’ll be honest, even to this day, I can’t watch some of the animal cruelty shown on TV and the internet.  So that brings me to my initial question, when exactly is the right time to show them one of these videos or really drive home the benefits of veganism, the pitfalls of eating meat and dairy, and then to let them make a decision on their own?  Is it when they are teenagers?  Is it when they become young “adults” what exactly is the right play?  I want to say when they are teenagers is the right call since this is when kids really begin to mature and open their eyes to what life is, it also a time when kids tend to really think and make decisions for themselves.  I guess time will tell but what do you think is the right time?
