Healthy compared to a Mars bar perhaps, compared to whole, natural foods it's sub optimal. I sometimes take stuff like that during long days of intense labor when 10 seconds is all the time I have to eat.
If you want a good meal replacer you should make one yourself, smoothies are fast and yet healthy. A similar thread btw: [url]http://www.eastsideboxing.com/forum/showthread.php?t=86082[/url]
