Berries may boost brain power

      Here's yet another reason to pile on those blueberries on your morning cereal.{} They aren't just high in antioxidants, a new study says they can actually boost brain power.

      The study included more than 16,000 women over the age of 70.{} Researchers found those who ate the most blueberries and strawberries had a slower rate of developing memory problems by about two and a half years.{}

      So how many berries must you eat to reap the benefits?{} About two half cup servings per week.

      The study could not prove if berries protected the women's brains directly.{} It also found that those who ate berries also exercised more and had higher incomes, both factors in having better health.
