About This Site

Protein or Fibre exists to cut through the noise of supplement marketing and provide concrete, peer-reviewed facts regarding the two most critical components of a modern diet.

Our Methodology

We do not sell supplements. We do not promote fad diets. We base our protein guidelines and fibre recommendations on data from the NHS (UK), FSANZ (Australia/New Zealand), and high-quality meta-analyses published in journals like The Lancet and the British Journal of Sports Medicine.

Why UK/AU Spelling?

Because the internet is heavily saturated with US-centric dietary advice. "Fiber" instead of fibre, USDA guidelines instead of NHS guidelines, and ounces instead of grams. This site is built for the Commonwealth.
