In that list, I think I’d only really miss apples and dairy (really just cheese) by their own virtue. Pork/beef/meat due to familiarity (which is to say, they had other meat sources, which I’m sure were just a good, if I’d grown up on venison I’m sure it would just taste like cow to me).
Potatoes and corn, losing though would be absolutely tragic. Also avocados.

Having grown up on plenty of both wild venison and farmed cattle, they are pretty different, not to mention that different types of venison are also quite different from each other. So I'm not sure I would consider venison and beef interchangeable simply by familiarity. White tailed deer and gemsbok, specifically, I find the best tasting and much better than beef.
