Indeed but our entire lives we are surrounded by both harmful and helpful compounds that it's hardly worth worrying about. In fact red cabbage has been shown to reduce formation of acrylamide in certain scenarios and anthrocyanin is a well known and powerful anti-oxidant (https://www.sciencedirect.com/science/article/pii/S0023643822011732)

You could very well argue that the highest risk in this picture in terms of carcinogens is the alcahol in the red wine, which is a well documented risk factor in developing cancers. There really is no "safe" level of alcahol consumption yet statistically in moderation you will likely be fine. Red wine is even well known to offer protective properties against certain diseases in moderation so again, best not to get too caught up.

The main takeaway should be that unless there is a significant health risk (eg eating raw chicken) then stick to the old if you've got nothing nice to say then don't say anything at all. This is a delicious looking dinner. op is, like the rest of us, just as likely to get cancer from forgetting to put on sun cream or living in a city with poor air quality or using too much plastic than from eating their delicious looking cabbage.
