Blueberries are so easy... dump your berries in to gallon size freezer bags and put them in the freezer. They are lower in moister than a lot of other things so they don't stick together. You'll be so glad you bought them when you're baking up fresh blueberry muffins later in the year.
Blueberries top the charts with antioxidants and have been shown to help with brain, eye and vascular health. Antioxidants are compounds that protect cells from free radical damage. Free radicals are highly reactive particles - induced by such things as cigarette smoking, sunlight and excessive exercise - that damage cells throughout the body by triggering oxidative reactions.
Not only are blueberries low in calories and high in fiber, they are packed with phytonutrients (plant compounds) that may promote healthy aging. In fact, preliminary studies focused on blueberry consumption have shown improved motor skills and a benefit in age-related short-term memory function. Blueberries may also provide other benefits such as supporting cardiovascular health and a healthy urinary tract.
You may not need a health-related reason to eat blueberries. They are just so delicious! But if you need one more, they're a low glycemic fruit, meaning that they raise blood sugar levels at a lower pace.
