It’s Week 5 of my 52-week journey! This week, I am diving into a topic that’s been hiding in plain sight: preservatives. They’re not just in our food; they’re in our beverages, cosmetics, and even our hair products.

Quick Summary: A Health and Nutrition Coach’s Guide to Reading Preservative Labels

Preservatives are added to extend shelf life by preventing the growth of bacteria and microorganisms, but too many synthetic additives can contribute to inflammation and other health issues. As a health and nutrition coach, I thought it was high time to introduce you to the numbers so you can start educating yourself about these pesky little codes, the same label literacy I build with clients before we even talk about diet.

Why Preservatives Are Hiding in Plain Sight

Here in Australia, preservatives are identified by specific E numbers that help you understand what you’re really consuming, information every health and nutrition coach wishes more people had at the supermarket.

Decoding the E-Numbers

It’s eye-opening when you think about how these little numbers on a label can reveal so much about what you’re consuming. Just imagine checking a juice product and discovering it contains synthetic preservatives like sodium benzoate (E211) and potassium sorbate (E202). Armed with this knowledge, and the kind of awareness a health and nutrition coach builds week by week, I’m committed to stripping away these additives from my diet wherever possible.

Natural vs. Synthetic Preservatives

Many synthetic preservatives have been linked to chronic, low-grade inflammation, which can manifest as fatigue, skin flare-ups, joint pain, or digestive discomfort. In contrast, natural preservatives such as vinegar, salt, rosemary extract, and certain vitamins, like Vitamin E, are substances our bodies are generally more accustomed to. 

This is the exact distinction a health and nutrition coach teaches clients to look for, not “preservative” as a blanket red flag, but which kind, in what quantity, and how often it shows up across a week of meals.

Why This Health and Nutrition Coach Goes Back to Basics

I have always believed that knowledge is power, which is why I’m taking the time this week to truly understand what goes into my food and everyday products. For me, this isn’t just an exercise; it’s about taking control of my health by stripping away the inflammatory triggers in my diet, the same pattern-spotting work I’ve carried through this 52-week journey since Week 4.

Preservatives, much like other hidden culprits, are everywhere. That’s why I’m going back to basics and preparing more from scratch, a shift any health and nutrition coach would recommend before reaching for another “clean label” product. Being a chef for over 35 years certainly gives me a leg up here. If you’re interested, I might even share some recipes that avoid these additives.

This week is all about peeling back the layers of what I consume and making informed choices that help my body thrive- the same identity-level awareness I walk women through inside Reclaim Her. Whether you’re checking the label on a can, a box, or even a beauty product, those numbers aren’t just there for decoration; they’re clues to how our food and products might be affecting our health.

Conclusion

If you’re curious about natural versus synthetic preservatives or want to learn more about Australian preservative codes, drop me a comment or send a message. Here’s to Week 5, embracing cleaner ingredients, reading labels with new eyes, and giving our bodies the respect they deserve. It’s the same guidance I offer as a health and nutrition coach inside Katrina Gl Coaching.

FAQs

What do E numbers actually mean on a food label?

They’re standardised codes identifying specific additives, including preservatives, so you can see exactly what’s been added beyond the main ingredients.

Are all preservatives bad for you? 

No. Natural preservatives like vinegar, salt, and rosemary extract are generally well tolerated; it’s certain synthetic additives linked to inflammation that are worth watching.

Which preservatives are most linked to inflammation? 

Sulfites, benzoates, and nitrates are commonly flagged and can show up as fatigue, skin flare-ups, joint pain, or digestive discomfort in sensitive people.

How can a health and nutrition coach help with label reading? 

By teaching you which codes matter, why, and how to build a simple, repeatable shopping habit around it instead of trying to memorise every number on sight.

Is cooking from scratch the only way to avoid preservatives? 

It’s the most reliable way, but reading labels carefull
