Saturated fats have sat in the middle of food arguments for years. Cheese plus red meat all carry them. Doctors once said those fats plug arteries and raise the odds of heart trouble. UK health leaflets still tell men to stay under 30 g a day and women under 20 g. Yet the science that backed those numbers is now wobbling.
Seventeen trials that followed more than 66 000 people show that trimming saturated fat hardly changes the chance of dying for the average person. Only volunteers who already faced a high heart disease risk gained any clear payoff from eating less fat. The rest saw almost no change over five years. The finding underlines a simple point - diet advice fits some bodies better than others but also genes or earlier illness steer the outcome.
Saturated fats raise blood cholesterol and higher cholesterol can invite heart disease. Even so the fats are not a single block. Different sub types exist and the food that carries them matters. A little butter on a plate of vegetables acts differently in the body than the same fat stirred into pastry. When saturated fat arrives alongside olive oil, nuts or fish oil, the overall pattern can still protect the heart. People who already have artery damage still need to watch the total amount, because large servings push cholesterol upward.
The NHS as well as the UK government hold the line - keep saturated fat under one tenth of daily calories. Advisers note that the new studies ran for five years, while heart risk forecasts look ahead at least ten. Until longer data arrive, the official plan stays cautious. Swap some butter or lard for olive oil, nuts, avocado or oily fish - the swap lowers saturated fat and lifts healthier fat in one move.
Fresh evidence keeps redrawing the picture of saturated fat. Many people do not need to erase butter or cheese from the kitchen - they need to set them in a wider, varied pattern of eating. Longer studies may sharpen the details later - yet the safest course today is to eat different fats, stay near the official limits and let the overall plate - not a single food - shape heart health.
