A walk through the produce section of a supermarket might leave you thinking we can have all kinds of delicious and nutritious fruits and vegetables year-round,at least until you actually bite into that January strawberry from South America.
These days, most produce in supermarkets comes from California, Florida, and other states with longer growing seasons, or is shipped in from other countries thousands of miles away. This is true even in the spring, summer, and fall, when local fruits and vegetables are available.
In order to survive journeys of over a thousand miles, most produce comes from varieties that have been bred for durability rather than flavor and nutrition. Most produce is also picked before it's truly ripe because ripe fruits and vegetables are more easily damaged in transit and rot more quickly. Unripe produce, however,hasn't yet reached its peak of flavor and nutrient content. Moreover, fruits and vegetables begin losing nutrients as soon as they're harvested, so more time spent in transit means less nutritious food.
