I’d say the Food Compass is probably not perfect, but in general it looks to be a useful way to get a sense of good vs. bad foods (yet as I noted, not revealing much that previous research and common sense haven’t already told us). As for your father and grandfather’s diets, we have to keep anecdotes in perspective. What science finds to be “good” or “bad” for us is all about averages and odds, offering information we can use, if we choose, to make lifestyle choices that work in our favor. Genetics and numerous other factors contribute to outliers — people who break all the rules and live long lives, and people who do everything “right” and die young. My dad smoked his entire adult life and cancer never got him… until he was 85. We’ll never know, but given his clear mind and lifelong good health otherwise, it’s reasonable to guess that had he not smoked, he might’ve lived in good health to 95, something his kids and grandkids would’ve been very happy to see. Many, many, many other people lost decades to smoking. I think of red meat and bacon this way: They’re not guaranteed to kill you tomorrow, but they’re not spinich or blueberries, either. Hope that’s helpful.
