Many plug-ins can do the job, but they’re not necessary at all. WordPress has a built-in RSS reader that is used, for example, to display news on your dashboard. All you have to do is use it in your theme.

<?php include_once(ABSPATH.WPINC.'/rss.php');
wp_rss('http://feeds.feedburner.com/wprecipes', 3); ?>
