BLACKBERRIES
You likely don’t have this fruit in your fridge on the regular—but it might be time to stock up. Shalek suggests this berry because it’s high in fiber, antioxidants, vitamin C, and folate, all of which have a positive impact on your health. She does warn to be careful of portion size because they contain sugar; however, the berry does prevent significant sugar spikes because of its fiber content.
Fiber per serving: 4 grams of fiber per 1/2 cup
