Supermarket shelves are packed with butter options, which can make picking the “healthiest” one feel like a coin toss. Salted, unsalted, plant-based, or light versions all promise something slightly different. Nutrition experts say the best place to start is the label, specifically the saturated fat per serving. Because butter is made by churning cream until the milk fat concentrates, it naturally ends up rich in saturated fat.
Three dietitians highlighted saturated fat as the first detail to compare from brand to brand. A standard tablespoon of butter contains about 7 grams of saturated fat, which is more than half of the commonly recommended daily limit of 13 grams for someone eating around 2,000 calories. Dietitian Juliana Crimi notes that knowing this number can make it clearer how quickly butter portions add up across a day. The goal is not to fear butter, but to understand how it fits into a bigger picture.
After checking fats, the ingredient list should be your next stop. Crimi recommends choosing butter made from just cream, or cream and salt. By definition, butter contains at least 80 percent milk fat, but many spreads and blended products fall outside that standard. They often include added oils, stabilizers, or flavorings, which does not automatically make them bad, but it does mean they are not the same as classic butter.
If butter is a daily staple in your kitchen, unsalted may be the smarter default. Salted butter can contain roughly 100 milligrams of sodium per tablespoon, which seems minor until it repeats across meals. Choosing unsalted gives you more control over how much salt ends up in your food, which matters for people watching blood pressure. It also makes baking easier when you want precision.
Grass-fed butter comes with its own buzz, and there is some truth behind it. It can have a slightly different fat profile, including more omega-3 fatty acids and CLA. Still, dietitian Serena Pratt emphasizes that grass-fed butter contains a similar amount of saturated fat to regular butter. Marketing claims deserve a second look, since “light” or “whipped” often just means more air or water, and plant-based butters made with coconut or palm oil can be just as high in saturated fat. Pratt also points out that “keto” is largely a redundant label for butter.
The most realistic strategy is to use butter where it delivers the most satisfaction. Instead of cooking everything in butter, add a small knob at the end for flavor, like on steamed vegetables or warm bread. For everyday sautéing and roasting, olive oil or avocado oil can be a better routine choice because they are richer in unsaturated fats. A little butter can also help the body absorb fat-soluble vitamins like A, D, E, and K found in vegetables, though other oils can offer a similar benefit.
