Every entry on this site is hand-researched and written by me, built on thousands of hours parsing data from EFSA, the WHO and the NHS. That, and a whole lot of coffee.

From the founder

I started NutraSafe because there's a lot of mystery in food, and very few people seem to understand what we eat. Part of that is what gets added to it, which we've truly been blind to. Part of it is what's naturally in there.

Take the balanced diet we're all told we need. I used to think that just meant balanced macros. In reality I probably didn't get much omega-3 through my early life, because it never crossed my mind.

NutraSafe is an app for logging food, the same as any calorie counter, but it tells a bigger story. Log a steak and you see what's in it, and that it carries a lot of B12. Log a "healthy" snack bar and you see 10 additives, with some genuinely concerning research behind a few of them. We want to lift the veil, give you accurate data, and let you track it over time. How was last month for vitamins and minerals? How many ultra-processed foods did you eat?

Building this has taken a lot of research. I don't claim to be an expert in nutrition, because I'm not. What I can do is research. Everything on this site is extensively researched and backed up with the source it came from. There's a large additive database I've been building for over a year, and the aim is simple: put all the relevant information I could find on each one in a single place.

I'm not pretending to be the be all and end all. I'm here to help. A paper could come out today that changes the picture on an additive completely, so please use this as a guide. If something matters to you, dig deep until you're certain. And if you have a question, or new information, send it to contact@nutrasafe.co.uk.

We want to make the world a better place. If enough people understand their food, we might see less disease, and fewer people buying products built only for profit that damage our health. With luck, it pushes the manufacturers to do better.

Thanks for reading.Aaron
How I research it

Where every entry comes from

The source documents

I read EFSA, the Food Standards Agency, the WHO and IARC, the NHS, SACN and CoFID directly.

A second source

Anything with a real concern gets checked against a second source before it goes on the page.

Written and checked by me

I write every entry myself and check it against its source. None of it is auto-generated.
