Are blueberries good for you? How much?

Blueberries are moderately low in calories and not excessively high in carbs or sugar. Their sugar content is moderated by a good content of dietary fiber which balances the effects on blood sugar of the berries. Otherwise, blueberries have a modest nutritional value, with good amounts of just vitamin C, vitamin K and manganese.

What recommends blueberries for regular consumption is not their calories or vitamins content, but their high content of antioxidants with scientifically proven free radical-scavenging and anti-inflammatory properties.

So long as you don’t go looking to get all the vitamin A or vitamin C you need in a day from blueberries, or your iron or calcium, they are definitely a good option for you. Amounts in the range of 100 grams to 200 grams are good serving sizes, enough to provide some nutrition and lots of antioxidants with a range of health benefits.
