When can you introduce sugar and chocolate to your kids diet?

Most parents choose to keep their kids away from sugary, chocolatey foods for as long as they can because of the view that these items are traditionally "unhealthy". Amongst my group of mommy friends, the first kind of chocolatey food item that they tend to introduce to their kids would be chocolate milk and the most common age recommendation is when their children turn two. As for real chocolate, they like to wait till the child is 3-4 years of age and most importantly, in small quantities at a gradual pace. Studies have shown that if introduced correctly and in modest quantities, chocolate, especially dark chocolate, can be a part of a healthy lifestyle for your child. http://www.foxnews.com/health/2012/06/14/benefits-dark-chocolate-tested-on-kids.html
