Ashlea Potts always makes sure fruits and vegetables are on her shopping list.
"I've always loved them. My parents got lucky."
Fruits and vegetables are packed with antioxidants that can boost the body's immune system.
But a new study finds there are some things antioxidants can't do.
"They looked at whether or not it reduced the rate of either dementia, Alzheimer's disease or stroke and unfortunately it did not do either," says Dr. Alan Lerner of University Hospitals Case Western Medical Center.
Harvard researchers followed more than 5,000 people over 14 years, tracking the food they ate. They found many got their antioxidants through coffee and tea.
"There is some suggestion that the source, actual what you eat, that not all antioxidants are created equal."
Doctors say eating fruits and vegetables is still the best source of antioxidants. And that getting plenty of those foods reduces the risk of obesity, heart disease and hypertension.
"The importance of a healthy balanced diet that tastes good cannot be underestimated."
At least half of Ashlea's diet is fruits and vegetables.
"It's really important to take care of my body."
She dances and acts so she says eating right is not only good for her health but for her work.
Broccoli, spinach, carrots, berries and apricots are all foods rich in antioxidants.
