Why Wellness Myths Spread So Easily
Wellness marketing often borrows the language of science — “detox,” “boosts,” “cleanses” — without the evidence to back it up. These claims spread because they’re simple and reassuring, not because they’re accurate. Here are seven common myths worth examining more closely.
Myth 1: “Detox” Teas and Powders Flush Toxins
Your liver and kidneys already filter and remove waste products continuously — that’s their job. No tea, powder, or juice cleanse has been shown to meaningfully accelerate this process in a healthy person. What these products often do is act as mild laxatives or diuretics, which can feel like “working” without doing anything a normal diet and hydration wouldn’t already achieve.
Myth 2: Natural Always Means Safe
Plenty of natural substances are potent, including some that interact with medication or aren’t suitable during pregnancy. “Natural” describes origin, not safety profile. It’s always worth checking with a pharmacist or GP before adding a new supplement if you’re on medication or pregnant.
Myth 3: One Ingredient Can “Boost” Your Metabolism
Metabolic rate is influenced by muscle mass, activity levels, sleep, and genetics far more than by any single food or supplement. Some ingredients have small, measurable thermogenic effects, but nothing close to what “metabolism boosting” marketing implies.
Myth 4: Supplements Can Replace a Poor Diet
Supplements are designed to supplement — the clue is in the name. They can fill specific, identified gaps, but no capsule or powder replicates the fibre, protein, and full micronutrient spread of whole food.
Myth 5: If a Little Is Good, More Is Better
Most nutrients and plant compounds follow a curve, not a straight line — benefits plateau and can reverse at high doses. Following the serving size on the label isn’t a marketing suggestion, it reflects where the evidence for that ingredient was actually established.
Myth 6: Higher Antioxidant (ORAC) Scores Mean Bigger Benefits
In May 2012, the USDA withdrew its ORAC antioxidant database entirely, stating that ORAC values have “no relevance to the effects of putative antioxidant compounds in humans” and that the scores were being routinely misused by food and supplement marketers to imply health benefits the lab measurement couldn’t actually support. ORAC only measures how a compound reacts in a test tube — not what happens once it’s digested, metabolised, and absorbed by the body. A high ORAC number isn’t meaningless as a lab measurement, but it isn’t a health claim either, and it hasn’t been an official one for over a decade.
Myth 7: “Superfood” Is a Recognised Nutritional Category
There’s no scientific or regulatory definition of “superfood” — it’s a marketing term, not a nutrition science one. In the UK and EU it’s treated as a general health claim under food-labelling law, meaning a business can’t just print it on packaging; the claim has to be backed by a specific, authorised health claim for that food under EU Regulation 1924/2006. We use “superfood” loosely on this site to mean “nutrient-dense,” not as a scientific classification — and it’s worth reading it the same way wherever else you come across it.
