A U. S. Department of Agriculture study has determined that watermelons stored at room temperature* are far more nutritious than those stored in the refrigerator. Apparently its power-packed carotenoids, lycopene and beta-carotene, continue to develop after a fully-ripe melon is picked, but the process is slowed by refrigeration. What's more, refrigerated watermelons spoil faster.
The news about watermelons makes me wonder if a similar process is going on with tomatoes, which are another rich source of carotenoids. Conventional wisdom says tomatoes should be stored at room temperature rather than in the refrigerator. This means we have to eat them rather quickly here in Florida, but I can attest to the superiority of their unrefrigerated flavor.
*70 degrees Fahrenheit, which according to the article is "room temperature in an air-conditioned home." I wonder whose home they are talking about, and what their power bills might be. Ours is now set at 78 degrees, a real luxury considering for years it was 84, but we're older, more self-indulgent, and (most of all) this overall setting keeps the computer rooms at a bearable level. Not that 70 degrees wouldn't be really nice....
