For so many years we have heard if you're looking for a healthy snack to eat frozen grapes. Why has no one ever suggested frozen blueberries? It has been proven by South Dakota State University that frozen blueberries deliver a bigger dose of disease-fighting antioxidants than fresh blueberries. The antioxidants in blueberries come from compounds called anthocyanins, which give blueberries their purple color. When blueberries are frozen they form ice crystals. These crystals when the berries are frozen disrupt the structure of the plant tissue and make anthocyanins more available.
Make no mistake frozen or fresh, blueberries have one of the highest antioxidant capacities among all fruits. Blueberries have high flavonoid content and has been found to help short-term and long-term memory. Blueberries also help with eyesight, and your cardiovascular system. The fruit also encourages a process called authophagy, or cell clean-up.
A cup of unsweetened frozen blueberries, contains just 79 calories per cup and 1 gram of fat. While a cup of grapes contains 105 calories per cup and 2.2 grams of fat. Eating both fruit instead of higher calorie foods, such as chips or candy can help prevent weight gain and even help you lose weight. I'm not here to say that grapes aren't healthy I'm just simply pointing out the better option.
If you're seeking to reduce your calorie intake here are some other pointers and benefits of blueberries that you can't necessarily have with grapes. Blueberries are multifaceted. Reduce the serving size of your cereal by fill the rest of your bowl with unsweetened frozen blueberries. Instead of syrup try having banana pancakes or plain yogurt with thawed frozen blueberries. For more flavorful oatmeal you can also drop some blueberries in their too. The options are limitless, those darn blueberries!
