It’s not you, it’s milk. Or bread. Or possibility the 82 other foods your body’s quietly begging you to stop eating. New national data has revealed the surprising everyday foods thousands of Australians are unknowingly incompatible with. And it’s not about allergies, intolerance or even sensitives, it’s about a lesser known but increasingly widespread issue: food incompatibility.
Australia has a well‑documented food‑reaction problem. Around 1 in 4 people believe they have some form of food intolerance, while food allergies affect up to 10 per cent of children and four per cent of adults.[1] Yet a third and largely overlooked issue is food incompatibility: a temporary mismatch between what you eat and your body’s current cellular or inflammatory state.
According to FoodFit – a leading Australian food compatibility testing service operating since 1985 – the issue for most people isn’t a diagnosed food allergy or intolerance. It’s an incompatibility that flares when common foods aggravate an already imbalanced system.
Each year, FoodFit receives upwards of 5000 symptomatology reports each year from natural health practitioners. From its analysis of 2856 reports in the last year, bloating, tiredness and rashes/itchy skin were identified as the top three symptoms plaguing Australians.[2]
Digestive issues like bloating, constipation, diarrhoea and flatulence dominated the top symptoms. But FoodFit’s analysis also flagged sinus problems, brain fog and headaches. On average, respondents were incompatible with 82 foods, many of them pantry staples.
Dennis Hodges, founder and CEO of FoodFit, says these symptoms are showing up in people with no diagnosed food allergy, no formal intolerance and often no clue what’s causing their discomfort.
“These aren’t just people who can’t tolerate lactose or gluten. These are people reacting to common foods like milk, bread and pasta but for reasons that have nothing to do with classic intolerances. Our testing identifies foods that are temporarily aggravating an imbalanced system. And that’s a massive difference,” says Dennis.
Unlike allergies, which trigger a direct immune response in the blood, or intolerances, which involve enzyme or metabolic deficiencies, food incompatibility which can be triggered by inflammation, stress and even environmental load.
In FoodFit’s recent analyses, four in five (85%) of symptomatic individuals were incompatible with basic supermarket foods. Among the top 10 offenders were full cream milk (95.5%), white bread (95.2%) and wholemeal bread (94.9%). Even multigrain bread, skim milk, A2 milk, pasta and cow’s milk cheese were flagged in more than 84 per cent of cases.
Also, unlike traditional allergy testing, FoodFit’s Compatibility Program doesn’t rely on blood samples or histamine markers. Instead, it uses hair and saliva to test over 600 whole foods and household products and then guides individuals through a short-term, practitioner-led elimination process to reduce inflammation and restore balance. Dennis says that many foods can be reintroduced once the body resets.
“Rather than diagnose allergies, our program helps people pinpoint which foods may be disrupting their system right now,” Dennis explains. “We’re not saying milk or bread are bad. We’re saying that your body, at this moment, may not be processing them well. This test isn’t the cure, but it’s the start of figuring out what’s throwing your system off.”
The million-dollar question is why more people are struggling with foods that, on the surface, appear perfectly acceptable. Dennis believes that these staples aren’t what they used to be.
“We’re eating out of season, relying on produce grown in depleted soils and consuming foods that are hybridised, irradiated or fumigated to extend shelf life. Add environmental stress and a modern diet that lacks diversity and you’ve got a recipe for incompatibility.”
FoodFit’s Compatibility Program is available exclusively through qualified practitioners and involves testing for 600 whole foods (not isolated nutrients) and household items, and a guided, practitioner-monitored elimination plan, at a one-off cost of $299.
