The Chilean Avocado Importers Association is marking American Heart Month in February with a Facebook contest whose winners will receive a book on menu planning for weight loss.

The association is featuring registered dietitian Cynthia Sass, author of the book “Cinch!” and co-author of “Flat Belly Diet!,” according to a news release.

A copy of “Cinch!” will be given away daily to contest winners throughout February.

The Facebook page is dubbed the Chilean Avocado Lovers Club.

“We’re delighted for the opportunity to offer Cynthia’s latest book to consumers during American Heart Month,” Maggie Bezart, marketing director at the trade association, said in the release. “We hope it inspires health-conscious consumers to eat more fruits and vegetables as part of a heart-healthy diet that includes Chilean hass avocados.”

Sass’ book, which made The New York Times bestseller list, includes a recipe for black bean tacos with cilantro jalapeño guacamole.

“I’m proud to partner with (them) during American Heart Month to remind people that diet and lifestyle play a key role in preventing cardiovascular disease,” Sass said in the release. “Chilean hass avocados contain the ‘good fats,’ monounsaturated and polyunsaturated fat, that can help meet the dietary guidelines of the American Heart Association.”
