Eating seasonally

The cheapest fruits and vegetables are said to be those that are currently in season. I'm a city girl. What do I know about growing seasons?

This handy site fills the gap: Fruits and Veggies More Matters. Here's what's in season for the winter months (December, January, February):

• Apples
• Belgian Endive
• Brussels Sprouts
• Cherimoya
• Chestnuts
• Dates
• Grapefruit
• Kale
• Kiwifruit
• Leeks
• Mushrooms
• Oranges
• Parsnips
• Pear
• Persimmons
• Pummelo
• Radicchio
• Red Currents
• Rutabagas
• Sweet Potatoes
• Tangerines
• Turnips
• Winter Squash

Once again, I have some issues. The dates would probably put me in a sugar coma. The grapefruit will counter half of the medications that I take with a similar result (coma). I have no clue what Pummelo is, but I have at least heard of Radicchio.

Nonetheless, I will start looking up the unknowns and give the knowns another look. Eating seasonally is cheaper--and better for the environment--so I need to try to do my part.
