Answer: Blackberries are one of the most keto-friendly fruits available.
One of the toughest challenges keto dieters face is the lack of fruit options. Fortunately, delicious blackberries are here to fill the gap.
A 100 g serving of blackberries (just under 3/4 cup) contains 4.3 g of net carbs. They contain 21 mg of Vitamin C, which represents almost 1/3rd of an adult's recommended daily consumption. Recent research shows that eating blackberries may slow down the negative effects of aging on brain health.
While fresh blackberries are keto-friendly, canned or dried blackberries are too carb-heavy to fit the keto diet. Manufacturers drench canned blackberries in sugary syrup, and they use dried berries contain tons of added sugar.
