Fight heart disease with a plant-based diet?

Here is a post from the Huffington post about fighting heart disease.
I like Huffingtonpost.com's living section , they have some good stuff there.

Still here

Wow , Its been a while since I have written anything.
Anyway I have been eating good but recently I have started eating lots of fried , sweet and calorie rich food , have to cut back.
I am drinking a lot of Green tea , hopefully its helping.
I am really not working out at all, have to do something about that. With the holiday season coming up there will lots of eating I am sure.

I should be either cutting back on unhealthy food or exercise more , ideally both of these right?
Anyway 1 of the 2 should be good for now.
I will start posing some good links soon.
