Today, she's explaining the health benefits of avocados - check her out in the video above.

Every week on Healthy Appetite, Pamela Flood challenges two of Ireland's top chefs to create two decadent dishes that esteemed Aveen will then deconstruct to reveal exactly how much fat, sugar and fibre is in each dish.
On tonight's episode, Paul Flynn from The Tannery, Dungarvan competes with Maria Raftery of Kernel Bar & Kitchen, Kilkenny.
The chefs must then come up with healthier versions of their decadent dishes in a head to head cook-off. By the looks of things, Paul Flynn is not too happy with his challenge.
