I'm getting somewhere

So my topic for this Food Politics unit is how food advertising affects the youth. It's basically dealing with how the food industries target mainly children and adolescents because of how vulnerable and susceptible they are to outside influences especially if what they're being sold is cheap and delicious. I'll also be discussing how families, schools, and even the food industries could improve themselves to better fit for children's health. It centers on what we've been doing wrong as role models for children and how we can make it better in time. It'll help for others to read altogether so we can try to implement the idea of eating better starting at home, then in school for kids to have a healthier life. I feel like my research might be running short in some areas of current articles, well really current details. My research is good from a few years ago, but it makes me nervous a bit if one of my sources isn't as recent as like yesterday. I guess I hope my research shows me how serious it can be to continue on a life style where we follow whatever food advertisements says and states the actual statistics of how this can negatively affect children. In a way what I need help finding for my research topic is numbers, like statistics and charts or graphs about the declining health of children in America due to food advertisements. Hopefully, I can find some information like that. Does anyone know a website like that? Or anything about childhood obesity? But is the complete article though? Because from what I've seen so far, they're only showing abstracts or summaries of the articles and if you want the rest, you'll have to rent or buy the article online. Honestly, I don't want to do that at all. If you have any info about that or maybe how to find the same article but without paying for it, then that'll be very helpful and I'll very much appreciate it. Good luck with your own research topics!!
