The Eatwell Guide recommends unsaturated oils and spreads in small amounts, and eating fewer foods high in saturated fat. Fat remains part of a balanced diet: oily fish (omega-3 fats), nuts, seeds and olive or rapeseed oil sit comfortably in heart-health advice when portions are sensible and the rest of the plate includes vegetables, pulses and wholegrains.
Unsaturated fats - monounsaturated and polyunsaturated - are found in olive and rapeseed oil, avocados, nuts, seeds and fish. SACN and NHS materials emphasise swapping some saturated fat for unsaturated fat to support healthy blood cholesterol levels in the population. That is why UK labels list total fat and saturates separately: the chemistry matters for long-term cardiovascular risk, even though any single meal is only one piece of the puzzle.
Why fat carries so many calories
Fat provides about 9 kcal per gram, compared with about 4 kcal per gram for protein or carbohydrate. A tablespoon of oil can add as much energy as a slice of bread without the same fibre or volume. That is not a reason to fear oil - it explains why creamy, fried or cheese-heavy recipes show higher calories per portion, and why draining excess fat or measuring oil can shift a week’s intake without tiny portions.
Clinical points I discuss with patients
People with gallstones, pancreatitis history, very high triglycerides or malabsorption need tailored advice - sometimes lower fat, sometimes different timing of fat with medicines. Statins and heart disease prevention are about the whole lifestyle (smoking, activity, blood pressure, diabetes) not one lamb roast. If you have been told to follow a specific fat prescription, use that in preference to any app traffic light.
Grill or bake instead of deep-frying where you can, use yogurt or milk in sauces instead of only cream, and keep nuts and cheese as flavour accents. Mediterranean-style cooking - vegetables, beans, fish, modest oil - aligns well with NHS heart-health messaging and is realistically achievable on a British weekly shop.
