Okay, so I've been using this book for like 3 months now and WOW - it's literally changed how I shop!

First thing: the E-number index is SO easy to use. I just flip to the back when I'm grocery shopping and bam - instant info on what's really in my food.

Massive shocker: Did you know E102 (tartrazine) is in so many 'healthy' snacks? This book saved me from so many asthma attacks!

The best part? It explains WHY certain additives are bad, not just listing them. Like how some E-numbers can trigger hyperactivity in kids (my nephew's teacher noticed a difference after we changed his snacks).

Only downside - it's a bit outdated (1988 edition). But honestly? Still super relevant for UK products. I just cross-check with some apps for newer additives.

Seriously, if you have allergies, asthma, or just care about what you eat - this is a MUST. Changed my life, no exaggeration!
