Everyone knows fruit is healthy, but surely not all fruit is created equal. From a nutritional perspective, when deciding which fruits to eat, we should favor those with more of the good stuff and less of the questionable stuff. The good stuff is vitamins, antioxidants, and phytonutrients. The questionable stuff is sugar.
Simply put, London is rubbish at food markets. Yes, we have Borough Market (inexplicably only open three days a week) and we have some very decent farmers' markets in suburban car parks, but there is nowhere in the capital that comes even close to the glorious Rialto Market in Venice or the sumptuous San Miguel Market in Madrid or the vibrant Cours Saleya Flower market in Nice.
