Dietitians weigh in: margarine vs butter health tradeoffs

Is margarine – Dietitians say margarine and butter may look similar, but they’re made differently and push different fat and nutrient profiles—so “healthier” depends on the specific product and a person’s goals.

On a grocery shelf, butter and margarine sit side by side—two tubs that promise the same basic job: make food taste better. But the similarity stops at the spread. Dietitians say the fats, ingredients, and even the health risks tied to each product can be strikingly different.

Amy Goodson, a nutritionist and registered dietitian at The Sports Nutrition Playbook, lays out the core difference bluntly: “margarine and butter are made very differently and contain different types of fats and nutrients.” They also vary in where they come from and how they’re used in cooking.

Butter is dairy. Margarine is typically plant-based. Those origins matter for cholesterol and the type of fats your body gets—whether you’re spreading it on warm pancakes or melting it into baked goods.

Butter vs. margarine: what’s actually in the spread

Mia Syn. a South Carolina-based registered dietitian and author of the cookbook “Mostly Plant-Based. ” explains that butter is made by churning cream until the fat separates from the liquid portion. “forming buttermilk and eventually solid butter.” Because the final product comes from animal fat this way. butter naturally contains cholesterol and is generally higher in saturated fat.

Margarine, Syn’s colleague Goodson says, was originally developed as a less expensive alternative to butter. Instead of dairy, it “is made from vegetable oils that are solidified through processing.” Those oils can include soybean, canola, sunflower, palm, or olive oil.

Goodson says manufacturers blend these oils with water and other ingredients to create a spread with a texture and appearance similar to butter. The result, she notes, is that “margarine is higher than butter in unsaturated fats.”

The downsides: cholesterol, processing, and calories

Neither option is a free pass.

Goodson says traditional butter contains a substantial amount of saturated fat, which can raise LDL (“bad”) cholesterol levels when consumed in excess. She also points to saturated fat being associated with increased cardiovascular risk, arterial plaque buildup, and heart disease.

Margarine can look better on paper because many modern versions contain more unsaturated fats. which have been associated with improved heart health and healthier cholesterol levels. For that reason. Syn says organizations like the American Heart Association generally recommend replacing foods high in saturated fat with foods containing more unsaturated fats. whenever possible.

Still, margarine has tradeoffs. Goodson notes that it can carry concerns because of its often higher levels of processing and the additives used to achieve a butter-like texture and shelf stability.

And then there’s the basic math. At roughly 100 calories per tablespoon apiece, both butter and margarine can be calorie-dense—meaning either can contribute to unwanted weight gain. “The key is watching portion sizes when consuming either option,” Goodson advises.

A quiet difference shows up in the nutrient story

Both spreads can provide nutrients, but they come from different places.

Goodson says butter naturally contains vitamin A, “which supports vision, skin and immune health.” She adds that butter also contains vitamin D, which supports bone health, and riboflavin, which helps the body convert food into energy.

Syn adds that butter has small amounts of vitamin E and vitamin K—important for antioxidant protection and normal blood clotting, respectively. Syn also points to butyrate, which has been studied for potential benefits to gut health.

Margarine, Goodson says, contains essential fatty acids that are important for cell function and overall health. She also notes that some margarines are fortified with vitamins A and D, “which are important for bone and immune support.”

So which is healthier? It depends on the label and your goal

When asked directly whether margarine is healthier than butter, Goodson doesn’t give a one-size answer. “Whether margarine is healthier than butter depends largely on the product and the individual’s health goals,” she says, adding that “the answer of which one is healthier isn’t one-size-fits-all.”

Syn suggests that for someone focused on heart health, “a soft margarine made with unsaturated plant oils may be a better option than butter.” For others who prefer minimally processed foods, she says moderate amounts of butter may fit comfortably into an otherwise balanced diet.

In the end, Goodson’s takeaway is the same no matter which tub ends up in your cart: “choosing the right type and using it appropriately matters more than labeling either butter or margarine as ‘better.’”
