not quite, since that one trip produced many pounds of fresh healthy food over many weeks, whereas a comparable amount of fresh produce from the grocery store takes many trips.
That said, it's a culture of food production that's really where the efficiency lies. That's people saving and trading seeds, helping each other farm and harvest, and bottling and canning for winter.
That's not only tremendously efficient if it's done locally, it's also fun.
If so, you have completely negated all energy savings.
