NICE and SACN: What They Are and Why We Use Them

In UK nutrition and healthcare, guidance is based on evidence rather than opinion. Two key bodies behind this are National Institute for Health and Care Excellence (NICE) and Scientific Advisory Committee on Nutrition (SACN).

NICE

National Institute for Health and Care Excellence (NICE) produces clinical and public health guidance used across the NHS. It focuses on how conditions should be assessed and managed in practice, including areas like obesity, diabetes, and cardiovascular disease.

SACN

Scientific Advisory Committee on Nutrition (SACN) advises the UK government on nutrition science. It sets nutrient reference values and reviews population evidence on diet and health.

Why we use them

We use NICE and SACN because they:

• Provide evidence-based standards

• Ensure consistency across healthcare

• Link nutrition science to clinical practice

• Reduce reliance on trends or misinformation

In short

• SACN = what the science says people need

• NICE = how we apply it in healthcare

Together, they form the backbone of credible UK nutrition guidance.

Our experience matters

We also build on over 12 years of hands-on, client-facing experience working across sport, clinical nutrition, and performance settings. That means the guidance we use from bodies such as NICE and SACN isn’t just theoretical - it’s applied daily with athletes, teams, and individuals in real-world environments. From supporting elite endurance athletes and tactical populations to everyday clients trying to improve energy, body composition, and long-term health, we’ve seen how evidence translates (and sometimes doesn’t) when it meets training load, shift work, travel, and real-life barriers. Those repeated, practical touchpoints shape how we interpret the research: keeping it evidence-led, but always grounded in what actually works when someone has to execute it under pressure, not just on paper.
