I highly recommend you to buy fruits and vegetables depending of the season. Right now it's the season for buying the Italian blood oranges. They are sold cheap in nets right now.These oranges are actually ordinary oranges. What makes them red in the meat and peel is the temperature differences between cold frosty late winter nights and warm days. The red colour is antocyanin an antioxidant good for your immune system. So beat the winter flu with a glass of fresh pressed blood orange.
