This is not the Pac-Man that I remember from the Games, like in "Pac-Land", "Pac n' Roll" or "Pac-Man World 2", where he was portrayed as an Adventurous Family Man, caring for his family and protecting his home from Ghosts. Yes, Pac-Man eats junk, but he had a balanced meal, like Cherries, Apples, and Grapes, to counteract with the Pac-Dot Cookies (Yes, they are cookies, not drugs). Also, according to the Hanna-Barbera Cartoon, Power Pellets grow on trees, so the Power Pellets are fruit.
What I don't like from this "Pac-Man" story is that he's a gluttonous teenage jerk, who focuses more on food rather than helping others. Because that's what we want to show our kids: making them fat by eating junk.
Also, I hate that there's a villain named Betrayus... who's named that for no reason other than to be tortured, that's like naming your child "Satan" for his misbehavior.
In closing, this Pac-Man from this show is a bad role model, and I prefer you go for the Hanna-Barbera cartoon if you want something Pac-Man Related.
