Why is a lot of content on slim.in from NHS or NIH?

Because frankly,

  1. it is the best researched content on the web,
  2. we totally believe in EVERYTHING they have to say, and
  3. you are more likely to trust them than if we said the same thing.

Please read the NHS editorial policy and the Behind the Headlines policies and processes. You can read about who NIH is and what they do here.
