To get the highest quality produce, it's typically best to select loose fruits and vegetables rather than those that are pre-packaged. When apples are picked individually, it's easy to spot soft ones, while you may unknowingly pick up apples that are past their prime when you purchase them in a large bag. Most fruits and vegetables are at their best when they're plump and firm but not hard. Some fruits, such as nectarines and mangos, should have a little give when squeezed, but you never want to pick produce that's mushy or soft. Heavier produce is usually better, as the extra weight indicates more juice. Buy only as much fresh produce as you can eat in a week. This is especially true of berries, bananas, tomatoes, peaches, and avocados.
