i am agree with you, i wrote that A generation or two ago, people may have chosen to live on an unhealthy diet, but they took that choice from their kids, in not teaching them how to live healthily. Do you think a 2 year old child has the mental compacity to decide to eat ****? No - that's the parent's choice! And do you think that child, if not taught, will ever decide to eat healthily? Probably not, because they never learnt the benefits of healthy eating. If a well-meaning bloke wants to inform families of the dangers of a bad diet, and show them that there is another option than the one they live.
You might think you are showing your kid love by buying them a Maccy Ds every day, allowing them to eat junk etc.., but what you are doing is saving them the pain of ever seeing their parents die - because probably living such an unhealthy life will send them to the grave before their parents.
