Re: noodles. My mom, mother-in-law, grandparents, etc always called any sort of pasta "noodles." (Grandma Griff probably does too) My family's from the Midwest, and my husband's is from the deep South, so I'm not sure it's a regional thing. He and I both use the name of the actual pasta, ie egg noodles, linguine, etc. Perhaps this has to do with the recent rise of foodie culture, which we're not exactly part of but which has rubbed off on people our age and younger, who have been heavily exposed to media and probably dined in a variety of restaurants with more sophisticated menu items (and descriptions) than our parents and older generations were accustomed to.
As for Ruby's meals - I don't think she needs to give them larger portions of pasta, rice, white bread, etc. But there ought to be a LOT more vegetables and fruits, and probably more protein. I don't consider balanced meals with adequate nutrition to be serving a feast every night.
Most of Ruby's kids will probably get her family's naturally thin figures, but Kevin has to actively fight paunchiness and we saw Shari restrict sugar and get involved in sports, which helped her trim down a bit. Not that she was ever overweight - but I think she has to try harder than Ruby and her sisters to stay thin.
I agree that a portion-restricted diet based on white carbs and "treats" is unlikely to create a healthy relationship with food. Feeling hungry (and getting cravings due to poor nutrition) can lead to hoarding, sneaking, and binging on unhealthy stuff, at least in my experience. Ruby now has the income to provide a better diet for her kids, and I can't understand why she doesn't.
Along the same line of thought, but more nitpicky - we know Ruby has no aversion to giving the kids loads of chores, so I wish she would switch out some of their responsibilities and instead get them involved in (healthy) meal planning and prep. I was left in charge of cooking dinner nightly with crappy, limited ingredients from the age of 10, which I can't really recommend. But I have enjoyed getting my stepgirl involved in meal prep from the time she was a toddler, which has been massively rewarding and has resulted in a girl Shari's age with a palate far more adventurous than my own.
