There was a contraversial announcment by the (World Health Organisation (WHO) this week that we should eat avoid red meat (possibly carcinogenic) and processed meat (probably carcinogenic).
Here is a link to a blog by nutritionalist & obesity expert, Zoe Harcombe, giving her thoughts and reaction to the WHO's announcment. At Farm Direct we admire Zoe a lot and thinks she speaks a lot of sense and so we very much recommend that you read her article, as it demonstrates some of the big flaws behind the announcment.
