<p><pre><code>  &gt; The Scientific Advisory Committee on Nutrition (SACN)
  &gt; has concluded that the recommended average population
  &gt; maximum intake of sugar should be halved: it should 
  &gt; not exceed 5% of total dietary energy.

If we say that an average man has nutritional requirements of 2500kcal per day, then these recommendations imply he should not consume more than 125kcal of sugar per day, which is 31.25 grams of sugar.<p>A ~350ml can of Coke contains 39 grams of sugar [1]. A ~600ml &#x27;Vitamin water&#x27; drink has 31 grams of sugar. A single McDonalds &#x27;McFlurry&#x27; dessert has 64 grams of sugar [2].<p>Even something &#x27;healthy&#x27; like a 250ml &#x27;pomegranates, blueberries &amp; acai&#x27; smoothie from &#x27;innocent drinks&#x27; has 35 grams of sugar [4].<p>I guess my point is that we want people to reduce their sugar intake to recommended levels, there needs to be a sea change in what&#x27;s seen as a normal diet. No one thinks that a &#x27;McFlurry&#x27; is a health food, but in my experience they&#x27;re not seen as a huge indulgence, despite being more than two-days worth of sugar-allowance for an average man, and more for an average woman.<p><pre><code>  [1] http:&#x2F;&#x2F;www.coca-colaproductfacts.com&#x2F;en&#x2F;coca-cola-products&#x2F;coca-cola&#x2F;
