Worth watching (though 90 minutes long and heavy on the chemistry) is Dr Robert Lustig's video Sugar: The Bitter Truth.
A more accessible programme on the same subject of just how harmful sugar can be, is probably Dr Mark Porter on BBC Radio 4 on Wednesday at 9pm.
If you looked at yesterday's video of Photoshopping you may see some resemblance between the model in the video (the 'after' shot) and Boticelli's Venus, above, painted around 1485. The enlarged eyes, the straightened nose, the full lips, the small chin, the unrealistic hair and that elongated neck.....?
Just saying. There's nothing new under the sun.
