Good news for the millions of UK households who reach for olive oil when cooking: the British Heart Foundation (BHF) has confirmed what Mediterranean cultures have long known – this golden liquid really can be good for your heart. But as with most things in nutrition, the key lies in how you use it.
The BHF's latest guidance confirms that olive oil deserves its reputation as a healthy fat, thanks to its high levels of monounsaturated fatty acids. These beneficial fats work by helping to lower your levels of LDL cholesterol – the type doctors often call 'bad' cholesterol – when you use olive oil instead of saturated and trans fats found in processed foods and some animal products. For your heart, this cholesterol-lowering effect translates into a reduced risk of heart disease and stroke.
However, the charity is keen to emphasise that more isn't necessarily better. Whilst olive oil offers clear health advantages, it remains calorie-dense – like all oils and fats. A tablespoon contains around 120 calories, so if you're drizzling it liberally without adjusting the rest of your diet or activity levels, those extra calories could contribute to weight gain over time. The message from heart health experts is clear: olive oil works best as part of a balanced approach to eating, not as a 'superfood' you can consume without limits.
For UK families looking to make healthier choices, the BHF suggests using olive oil as a replacement for less healthy fats in your kitchen. This means swapping out butter, lard, or vegetable oils high in saturated fats when you're cooking, making salad dressings, or even baking. This approach mirrors the traditional Mediterranean diet, which has been extensively studied and consistently linked to better heart health outcomes.
The bottom line? Olive oil can indeed play a valuable role in supporting your cardiovascular health, but it's not a miracle cure on its own. Its benefits shine brightest when it's part of an overall healthy eating pattern that includes plenty of fruits, vegetables, and whole grains, combined with regular physical activity. As with most aspects of good nutrition, balance and moderation remain key.
