Here’s a truth the health industry often tiptoes around: butter isn’t the culinary villain it’s been made out to be, but it’s not as innocent as glowing advertisements for plant-based oils might suggest either. Could swapping butter for plant oils like olive oil or canola transform your health, and longevity, like the studies claim? Emerging research shows that this one pivot might reduce cancer-related deaths and overall mortality by up to 17%. Yet many chefs, nutrition experts, and biohackers in Malta overlook the surprising complexities lurking in this seemingly straightforward substitution. This 2026 guide explores whether switching from butter to oil substitutes is the answer, and reveals insider strategies to choose the best options for your specific goals.
Why should butter vs. plant oils matter to you?
Butter has long been a staple of Mediterranean cuisine, tantalizing taste buds from Valletta to Marsaxlokk with its luxurious texture in everything from pastries to sauces. But research from Mass General Brigham and Harvard reveals unsettling connections between butter consumption and higher risks of total mortality and cancer deaths. On the flip side, plant-based oils, like olive, soybean, and canola, offer antioxidants, essential fatty acids, and unsaturated fats that support heart health, lower chronic inflammation, and reduce cardiovascular risk.
For longevity enthusiasts, restaurant owners, and health-conscious cooks, this raises critical questions: can butter really be replaced without sacrificing flavor? And are plant oils all they’re cracked up to be? Let’s unpack the science and practical strategies behind this dietary swap.
What are plant-based oils, and how do they compare to butter?
Plant-based oils, such as extra virgin olive oil, canola oil, or soybean oil, derive their fats from seeds, fruits, or nuts. They’re celebrated for packing heart-healthy unsaturated fats, antioxidants, and omega-3 fatty acids into everyday cooking. Butter, by comparison, contains high levels of saturated fat, which elevates cholesterol levels and amplifies risks of coronary heart disease and systemic inflammation.
The key difference lies in fat composition. Plant oils feature polyunsaturated fats and monounsaturated fats, which actively lower LDL cholesterol (“bad cholesterol”) while promoting HDL cholesterol (“good cholesterol”). But the story isn’t as simple as swapping one food for the other, context matters. Both butter and plant oils function differently in baking, frying, and emulsifying, and knowing their culinary properties can transform how your dishes perform.
Can replacing butter with oil really increase longevity?
According to a 33-year study published in the Internal Medicine Journal and cited by PubMed, replacing just 10 grams of butter per day with equal calories from plant-based oils reduces mortality risk by an estimated 17%. The researchers tracked diet and health outcomes of over 221,000 adults, finding that higher butter consumption correlated with increased risks of total and cancer-related mortality.
The plant oil substitution wasn’t just theoretical, it demonstrated real-world reductions in cancer deaths, especially when oils like olive, canola, and soy were consumed regularly. For longevity enthusiasts living in Malta, this swap aligns well with Mediterranean nutritional principles already proven to extend life expectancy.
