I used to be a lot more particular when DD was little but now that she insists on having what we are. . .let's just say my standards have relaxed a little.
The thought of Christmas oranges, clementines, etc. is a tradition because they are in some parts of the country unavailable at that time of year and because 100 years ago we didn't have huge supermarkets, etc. where we could buy oranges, bananas, etc. whenever we felt like it. Christmas oranges was, and to some of us still are, a treat!
Remember the Little House on the Prarie books? They ate corn mush all year long and longed for spring and summer produce and berries. We are privileged to have fresh foods all year long but many are not seasonal. I can guarantee you that there are not a whole lot of orange trees in NYC right now!
I'm not suggesting we go on deprivation diets and did I mention I'm not so strict myself? When my DD was itty bitty little I gave her just what fruits were "seasonably" available, with what limited knowledge I had of such matters. I don't sweat it, now.
I have to add that there are some who believe that since juicing eliminates much of the fiber, etc. that juice is not a "whole" food and should be limited. How many of us moms water down the juice to limit the sugar? A lot. Good sugars are still sugars and hard to cut - a self-admitted sugar addict here - it's not easy.
All that being said - let's get back to enjoying foods. By all means enjoy Christmas oranges! Sure beats Christmas chocolate in the health dept.
