I know this is an aside, but I think what GH meant was that younger people today, perhaps moreso the educated crowd, are more conscious of food choices.
Eating at a massive wedding shmorg an hour before eating a full-size wedding dinner? Serving massive plates of oil-flowing potato kugel and cholent at your shul kiddush, and then going home to eat a massive shabbos lunch whose only vegetables are the the potatoes and onions in yet another cholent? Want to give your kids candy for answering a dozen parsha questions, then potato chips at pirchei and pizza and soda at avos ubanim? All while implicitly discouraging exercise? These are fine choices (it’s a free country!), but don’t be surprised if you find high rates of diabetes, heart problems, and teeth decay that are typically associated with the poorest populations.
