The Internet is a great place for a virtual punch-up. Nobody gets physically hurt (feelings can get very hurt!) and the end result is often educational as well as entertaining. Such a punch-up has just occurred between Alan Aragon (who's in my blog list) and Robert H. Lustig, M.D. (whose video is linked to in An apple a day...) plus quite a few others, including me.
Alan's blog post The bitter truth about fructose alarmism has caused a bit of a stir in the nutritional blogosphere.
Dr Lustig pointed out that lots of people have watched his video. If only Alan had some videos. Oh, wait! He has. They're in Conversations with a bro: animated edition. Also, see Alan Aragon on Paleo Cream Puffs and Is_Fructose_causing_problems_and_is_pointing_this_out_Alarmism_.mp4
