Question 4 of 20 Correct

Which form of blueberry gives you the most health benefits?

Correct! Sorry, that’s incorrect.

Of course, you won't get the fiber from the berries this way, so eating the berries themselves is still important.

True or false: Blueberries are a natural anti-diarrhea remedy.

Correct! Sorry, that’s incorrect.

Which of these is the best way to freeze blueberries?

Correct! Sorry, that’s incorrect.

The correct answer is: Blueberries can be frozen -- and make a great treat in winter months when fruit isn't so fresh -- but you have to freeze them correctly so they'll thaw well, too. First, wash and drain the berries. Remove any berries that are rotting or molded. Pour the berries into a single layer on a cookie sheet, and put the cookie sheet in the freezer. Leave the berries in the freezer until they're frozen hard, then pour them into a covered container or zip-top bag.
