Smart Balance is a reasonable alternative to butter, but it’s not the superfood its marketing suggests. The original buttery spread has 9 grams of fat per tablespoon (2.5 grams saturated), which is a significant improvement over butter’s 7 grams of saturated fat per tablespoon. Whether it qualifies as “healthy” depends on what you’re comparing it to and how much you use.
What’s Actually in Smart Balance
The primary ingredient in Smart Balance Original is a blend of palm oil and canola oil, followed by water. Olive oil and flaxseed oil also appear on the label, but both are listed under the “less than 2%” category, meaning their presence is more symbolic than nutritional. The rest of the ingredients include pea protein isolate, sunflower lecithin, natural and artificial flavors, and preservatives.
Per tablespoon, the fat breakdown looks like this: 2.5 grams saturated, 4.5 grams monounsaturated, and 2 grams polyunsaturated. That ratio is genuinely better than butter, which is about 51% saturated fat. Smart Balance also contains no hydrogenated or partially hydrogenated oils, so trans fats aren’t a concern. It’s fortified with vitamin D (20% of the daily value per tablespoon) and vitamin A, and it’s both dairy-free and gluten-free.
The Palm Oil Question
Palm oil being the first ingredient is worth noting. While palm oil is free of trans fats, it’s roughly 50% saturated fat, which is why Smart Balance still contains 2.5 grams of saturated fat per serving. It’s a middle-ground oil: better than the hydrogenated vegetable oils that older margarines relied on, but not as heart-friendly as olive oil or canola oil on their own. Palm oil also carries significant environmental concerns related to deforestation, which matters to some buyers even if it doesn’t affect the nutritional profile.
How It Compares to Butter
A large study of over 71,000 women tracked for an average of 13 years found that replacing butter with tub margarine (the category Smart Balance falls into) was associated with a lower risk of heart attack. Women who exclusively used tub margarine instead of butter had an 8% lower risk of heart attack compared to butter users. That’s a modest but real difference over time.
The reason comes down to fat composition. Butter is about 51% saturated fat and 3% polyunsaturated fat. Tub margarines like Smart Balance are roughly 14% saturated fat and 27% polyunsaturated fat. Saturated fat raises LDL cholesterol (the kind that contributes to arterial plaque), while polyunsaturated fat tends to lower it. The same study found that stick margarines, which contain more trans fats, offered no benefit over butter. Tub spreads are the better pick if you’re choosing between them.
The Omega-3 Claim
Smart Balance markets itself partly on its omega-3 content, sourced from flaxseed oil and canola oil. The omega-3 in these plant oils is ALA (alpha-linolenic acid), which your body converts to the more active EPA and DHA forms at a very low rate, typically under 10%. This is a different nutritional story than eating salmon or taking fish oil. The amount of flaxseed oil in Smart Balance is also minimal, listed at less than 2% of the product.
Meanwhile, canola oil provides both omega-3 and omega-6 fatty acids, but the typical Western diet already delivers omega-6 and omega-3 in a ratio of about 16 to 1, far higher than the roughly 2 to 1 ratio considered optimal. A tablespoon of Smart Balance won’t meaningfully shift that ratio in either direction. If omega-3 intake is a priority, fatty fish or a dedicated supplement will do far more than a buttery spread.
Cooking Limitations
Smart Balance works well as a spread on toast or melted over vegetables, but it’s not ideal for high-heat cooking. Because it contains water and various emulsifiers, it doesn’t behave like pure oil or butter in a hot pan. Users report that the flavor compounds can turn bitter at higher temperatures, making it a poor choice for searing or pan-frying. If you need a cooking fat for high heat, a pure oil like avocado oil or regular canola oil is a better option. Smart Balance is best used at the table or in low-heat applications.
Who Benefits Most From Switching
If you currently use a lot of butter and you’re trying to reduce saturated fat intake, Smart Balance is a practical swap. You’ll cut your saturated fat by roughly two-thirds per tablespoon while keeping a similar taste and texture on bread or baked potatoes. For people managing high cholesterol, that reduction adds up over weeks and months.
If you’re already using olive oil as your primary fat, switching to Smart Balance wouldn’t be an upgrade. Olive oil has a stronger evidence base for heart health, and it doesn’t come with the processed ingredient list. The healthiest approach to dietary fat isn’t really about finding the perfect spread. It’s about using liquid plant oils (olive, canola, avocado) as your main cooking fats and keeping any solid spread, whether butter or margarine, as an occasional addition rather than a staple.
Smart Balance is also a useful option for people avoiding dairy. It’s certified dairy-free and gluten-free, and it contains no animal-derived ingredients in the original formula, making it suitable for most plant-based diets. Just check the label on flavored or specialty versions, as formulations can vary.
The Bottom Line on “Healthy”
Smart Balance is healthier than butter by most cardiovascular measures. It’s lower in saturated fat, free of trans fats, and associated with modestly better heart outcomes in large studies. But it’s still a processed spread made primarily from palm oil, with trace amounts of the premium oils highlighted in its branding. It’s a better choice, not a health food. Using it sparingly alongside whole-food fat sources like nuts, avocados, and olive oil gives you the best of both worlds.
