5 Common "Health Foods" That May Be Driving Inflammation
5 Common "Health Foods" That May Be Driving Inflammation
Walk down the health-food aisle of any New Zealand supermarket and you'll see hundreds of products marketed as good for you. Granola, low-fat yoghurt, vegetable oils, protein bars, smoothies — the marketing is consistent, confident, and often misleading.
The challenge isn't that these foods are bad in some absolute sense. It's that many of them are quietly contributing to the kind of low-grade chronic inflammation that Furman and colleagues described in Nature Medicine as one of the most significant drivers of long-term health issues globally.
Below are five common health foods to avoid — or at least look at twice — if you're trying to take inflammation seriously. This is the short list. The full picture is what we cover at our upcoming Patient Health Workshop.
1. Industrial Seed and Vegetable Oils
Sunflower, soybean, canola, corn, and "vegetable" oil have been marketed as heart-healthy alternatives to butter for decades. They're cheap, shelf-stable, and used in nearly every processed food on the supermarket shelf.
The issue isn't fat — it's the omega-6 to omega-3 ratio. Modern diets often run at ratios of 15:1 or 20:1, when ancestral diets sat closer to 1:1 to 4:1. Research by Simopoulos and others has explored how this imbalance can shift the body toward a more pro-inflammatory baseline. These oils show up in places people don't expect — including many "healthy" salad dressings and baked snacks.
2. Flavoured and "Low-Fat" Yoghurts
Plain, full-fat yoghurt is a fermented food with potential gut-supporting properties. Flavoured low-fat yoghurts often look similar on the shelf but tell a different story on the label.
When fat gets removed, sugar typically gets added to make up for the loss in flavour. A single small tub can contain as much sugar as a chocolate bar. Sweeteners, thickeners, and "natural flavours" round out the rest. The yoghurt itself isn't the problem — the marketing is.
3. Granola, Muesli Bars and Other "Healthy" Snacks
The packaging usually says oats, seeds, and natural goodness. The ingredient list often tells a more complicated story: rice syrup, glucose syrup, vegetable oils, sugar, and a blend of preservatives.
Many of these products deliver a sugar load comparable to a soft drink with a fraction of the satiety. They become a default "healthy" snack and quietly add up across the week.
4. Most Bottled Smoothies and Juices
A whole orange contains fibre, water, and a small amount of natural sugar bound up in the pulp. Bottled orange juice removes the fibre, concentrates the sugar, and frequently adds more on top.
Bottled green smoothies often follow the same pattern. They're treated as a vegetable serve, but many are sugar-dominant once you read the label. If you're drinking one daily, it's worth a closer look.
5. Protein Bars and Meal Replacement Snacks
Protein bars are pitched as functional, performance-oriented snacks. The reality varies enormously by brand. Some are reasonable. Many contain refined sugars, sugar alcohols, soy protein isolate, and seed oils — packaged as wellness.
If you train hard or work long days, the goal isn't to avoid bars entirely. It's to read the back of the packet, not the front.
Why Any of This Matters for the Spine
Chronic low-grade inflammation doesn't just affect your gut or your weight. It influences how the nervous system, joints, and connective tissues respond to physical load. People who come to us with long-standing musculoskeletal complaints often haven't connected what they're eating with how their body is recovering — but the science suggests these inputs matter.
Structural assessment looks at what's happening in the spine itself. Inputs like food, sleep, and stress influence the environment that structure operates in. Both pieces matter for long-term outcomes.
This is the short list. The rest is at the workshop.
At our upcoming Patient Health Workshop, we walk through the full set of common "health foods" worth a second look — plus the small daily shifts that have the biggest impact on inflammation. Free to attend, designed for people who want to make better-informed decisions, not be sold a programme.
