Precipitation on Cape Cod and the islands of Martha's Vineyard and Nantucket is the lowest in the New England region, averaging slightly less than 40 inches (100 cm) a year (most parts of New England average 42 to 46 inches (110 to 120 cm)).
It may not necessarily be optimal or have any variety. A balanced diet refers to a diet that does not have too much of just one thing. For instance, if you eat nothing but rice, pasta, potatoes, bread, and corn, then that is NOT a balanced diet because it has too many starches and not enough protein, fiber, or fat.
Eating a balanced diet means primarily choosing minimally processed and natural foods. In addition, drinking plenty of water and choosing plant-based or lean protein (fish, low-fat dairy, lean meats) is part of a balanced diet. A plant-based diet doesn't have to be 100% plants or vegan, but it can be if you wish. The goal is for a majority of the foods you are eating to come from plants.
