While fruits are a healthy dietary source, some are somewhat heavy in carbohydrates, making them incompatible with keto. Berries, on the other hand, can be consumed in moderation. Though blueberries should be avoided since their carbohydrates may quickly build up, blackberries are OK for a keto diet. Eating berries daily shouldn't cause any problems provided you don't go overboard. There are several different varieties of berries, each with its own flavor and color. All berries contain antioxidants and other nutrients that help protect our bodies against disease. In addition to being delicious by themselves, berries are often used as ingredients in recipes where they're combined with other foods such as cheeses, meats, and desserts. On keto, you might want to limit yourself to one or two servings of fruit per day. This will allow you to enjoy the benefits of fruits without consuming too many carbs. If you want to eat more berries, try adding them to smoothies or salads. Berries are a good source of fiber and vitamin C. They also have moderate amounts of calcium and potassium. However, due to the high sugar content of many berries, they won't provide much energy - only about 20 calories per cup. That's half the energy content of a glass of wine or beer. The best way to benefit from berries is simply by eating them.
