The word chemical is often used as shorthand for something harmful, but it’s misleading. Everything we eat is made of chemicals. Water is a chemical. Fibre is a chemical. Vitamins and minerals are chemicals.
In the context of food, additives are substances added to improve safety, stability, shelf life, texture or consistency. They help prevent spoilage, maintain colour, stop separation and keep foods safe to eat for longer. Realistically, most of us rely on them to some degree; very few people make everything from scratch.
Additives span a wide range of categories, including preservatives, antioxidants, sweeteners, colourings and emulsifiers. But this is where nuance matters. Each class behaves differently in the body. And within those classes, each individual additive – of which hundreds are approved by health authorities – has its own structure, metabolism and potential effects on the body.
Lumping them together as a single group overlooks the complexity of how the gut responds to different compounds, and how those compounds interact within the foods that contain them.
The more useful question isn’t simply whether a food contains additives, but which ones, in what amounts, how frequently they’re consumed, and by who.
