It's really easy to romanticize the past, including the kitchen table of the past, but a recent Freakanomics podcast I listened to suggests that some caution should be involved in that. That's no surprise really, but it is something that we rarely consider.
In our minds, the table of the past was always the place where home cooked meals were served, with fresh food of all kinds. But this really wasn't so. For one thing, refrigeration was not really terribly advanced until the 1930s or so. Prior to that, a lot of people had an "ice box". My father still referred to the refrigerator at the "ice box" in the 1970s, not really switching over to "refrigerator" until the 80s. An ice box isn't anywhere as efficient as a refrigerator.
People compensated for that by buying food every day, but that couldn't really take care of the entire problem. Fresh food simply isn't available every day, everywhere. Frozen food wasn't really fully available year around. Canned food was, in the 20th Century of course, but it wasn't always as good as the canned food we have now. Salted and pickled food made up for part of the problem.
And food variety was necessarily much more restricted. It isn't as if you could expect to buy oranges everywhere easily prior to relatively efficient transportation. Something like a Kiwi fruit would have been unheard of. Even when I was a kid fish came from the river or from a box in the freezer section of the grocery store. In the early 20th Century here fish would have been from the river, and that's about it.
Food related diseases, such as rickets and goiter, that are attributable to a simple dietary deficiencies. Vitamin D is now put in milk to address rickets, but when most people bought milk in glass bottles that was from a local creamery, this wasn't true. Iodine is now in salt, but it wasn't always.
In looking at images from the past, a full farm larder is easy to imagine. But that isn't always the way things were.
An interesting look at an aspect of this, in military terms, is on this
