Nutrition attracts more myths than almost any other subject. Some are harmless, some waste money, and a few genuinely get in the way of feeling better.
Here are the ones our registered dietitians hear most often — with what the evidence, and our clinics, actually suggest instead.
Myth: carbohydrates are the enemy
Carbohydrates are your body's preferred fuel. The real question is quality and quantity: wholegrains, beans, lentils, vegetables and fruit behave very differently from refined white bread, sugary cereals and fizzy drinks.
Rather than cutting a whole food group, most people do better by swapping the refined versions for the slower, fibre-rich ones and matching portions to their activity and goals.
Myth: you must eat every couple of hours
Frequent snacking is not a rule of good health. For many people, a few satisfying meals with genuine hunger in between works better for appetite control, digestion and the constant background grazing that makes calorie awareness impossible.
That said, snacking helps some people — those managing medical conditions, athletes, or anyone who simply functions better that way. The trick is to make it deliberate rather than accidental.
Myth: fresh always beats frozen
Frozen vegetables and fruit are picked at peak ripeness and frozen quickly, which locks in nutrients. They are also cheaper, last longer and reduce food waste — three excellent reasons to keep your freezer stocked.
Tinned beans, tomatoes and fish are similarly useful, as long as you watch added salt and sugar. Fresh is lovely; frozen and tinned are not a compromise.
Myth: you need a detox or cleanse
Your liver and kidneys already detoxify your body, every hour of every day. Herbal teas, juices and cleanse programmes mostly work by making people eat and drink less for a while — which explains the short term change, not a permanent fix.
If you want to feel lighter and more energetic, a few weeks of consistent, ordinary, well-balanced eating will do far more than any cleanse.
Myth: healthy eating has to be expensive
Fresh berries, exotic grains and pressed juices get the attention, but the affordable workhorses — oats, beans, lentils, eggs, frozen vegetables, tinned fish, seasonal produce and plain yoghurt — do the heavy lifting.
Cooking one or two flexible base recipes and building meals from them reduces both cost and decision fatigue. Our dietitians routinely plan around a weekly budget.
Myth: it is all about willpower
Willpower is a poor foundation for long-term change. Environment, stress, sleep, medication, hormones, cultural expectations and mental health all shape how we eat — and ignoring that sets people up to fail.
We work on the surroundings instead: what is in the fridge, what is in the cupboard, what happens at that difficult hour of the evening, and what support you need on the days that wobble.
How we help you build habits that stick
Our nutrition and wellness service starts with a conversation about what you actually eat, what you enjoy, who you cook for and what your week looks like. Plans are then built around that reality, adjusted at regular reviews, and supported with practical coaching rather than lectures.
If food and weight have felt like a battle for years, you are not the problem — the plan was. Let us build a better one.
Good nutrition is not a personality trait or a test you can fail. It is a set of skills, and they can be learned with a bit of guidance. If you would like that guidance tailored to your own kitchen, our team is ready.
