The 50 Best Websites of 2011

Scientist Darya Pino's blog, Summer Tomato, helps make healthy eating a delicious activity, not a hardship. It features photographic visits to sumptuous-looking farmers' markets around the world, mouthwatering recipes, answers to readers' questions and links to items she recommends elsewhere on the Web. Even when Pino's advice about "upgrading your healthstyle" runs the risk of displeasing your taste buds, it deserves respect. (If you love bananas, you might not be crazy about her post explaining why she avoids them — but read it anyway.)
