In this Medical Update, why diabetics may want to go nuts over walnuts and can a brain scan tell you if someone is lying?

News on 6 anchor LeAnne Taylor asks how can you tell when someone's lying? A new study finds a brain scan may hold the answer.

Using Magnetic Resonance Imaging, or MRI, researchers identified activity in seven areas of the brain when a person lied and just four areas when a person told the truth. Although more study is needed scientists believe they may have the beginnings of a more accurate lie detector.

New research provides further evidence dark leafy greens are good for the eyes. Investigators found spinach, kale and other green vegetables help protect aging eyes from cataracts. In experiments, eye cells treated with specific antioxidants in those vegetables showed less damage after exposure to ultraviolet rays.

And people with type 2 diabetes could boost their health with walnuts. A new study found adding the nuts to an already healthy diet may help diabetics improve cholesterol and reduce the risk of heart disease.

Experts say walnuts are an easy way for people with type 2 diabetes to put the right fats and fatty acids into their diet.
