The butter industry is projected to reach approximately $49.91 billion by the end of 2024, with an annual growth of 5.94% until 2029, according to a Statista market analysis. Grocery stores now offer a wide array of butter and margarine options, driven by trends emphasizing health, organic practices, sustainability, artisanal qualities, and social media influence. While many modern guidelines recommend reducing or limiting dairy and butter, the removal of partially hydrogenated oils from many butter products has changed the landscape.
The Evolution of Butter: From Villain to Acceptable
In the past, butter's reputation suffered due to the presence of partially hydrogenated oils, semi-solid shortenings created by adding hydrogen molecules to vegetable oils. This hydrogenation process increased trans fat content and saturated fat, reducing healthy polyunsaturated fatty acids and raising the risk of heart disease. Partially hydrogenated oils were used to extend shelf life and stabilize flavors.
Today, with the removal of partially hydrogenated oils (though you may still find hydrogenated, fully hydrogenated, or interesterified oils), butter can fit into various dietary patterns. The butter versus margarine debate has evolved, offering a spectrum of spreads.
What Exactly is Butter?
Butter is created by churning cream, a process that separates fat from liquid. The liquid becomes buttermilk, and the remaining solid transforms into butter, which is then kneaded to achieve a consistent texture. Salt is sometimes added for flavor and preservation.
Margarines, by law, must contain 80% fat, while spreads have no specific fat percentage requirement. Many spreads in the market contain between 40% and 60% fat, often based on olive, canola, or sunflower oils, each providing a unique taste.

The Role of Fats: Saturated vs. Unsaturated
Butter has a high fat content, largely saturated fat, which has been linked to increased cholesterol levels and heart disease risk. Replacing butter with margarines and spreads made from healthy oils is a good way to reduce saturated fat intake.
Conjugated Linoleic Acid (CLA): A Closer Look
Butter is a source of conjugated linoleic acid, an omega-6 fatty acid. A meta-analysis of 18 studies suggested that an average intake of 3.2 grams of conjugated linoleic acid could lead to about a 1-pound weight loss per week. However, a tablespoon of butter contains only about 3.5 to 6.0 milligrams of fat (up to 110 milligrams in grass-fed butter). To reach the 3200-milligram target, one would need to consume an impractical 533 tablespoons of butter daily. Other CLA sources include grass-fed beef, sunflower seeds, and cheese.
Nutritional Value Beyond Fat
A tablespoon of butter provides roughly 14% of daily Vitamin A needs, crucial for DNA development and the normal function of the heart and lungs during pregnancy. It also offers a small amount of Vitamin B12.
Butter and Heart Health: What's the Verdict?
Due to its high saturated fat content, butter is not the best choice for heart health. Spreads with less saturated fat and more heart-healthy monounsaturated and polyunsaturated fats are preferable. Some spreads blend butter or buttermilk with plant oils, offering a buttery taste with reduced saturated fat.
Less-Processed Alternatives to Butter
Several less-processed alternatives to butter include avocado, peanut butter, other nut and seed butters, and hummus. These options provide fiber, healthy fats, and sometimes protein.

Butter in Baking: Substitutes for Heart Health
Alternatives for butter in baking include canola, rice bran, and sunflower oil, which are good for moisture in recipes like carrot cakes. Spreads around 60 percent fat content are also suitable for baking. Nut butters add richness, protein, and flavor, while fruit purees contribute moisture and natural sweetness. The type of baking recipe matters, as some, like biscuits, may require butter for a firm texture.
Making Informed Choices: The Bottom Line
Replacing butter with healthier options reduces saturated fat intake. Saturated fats should only be a small part of your fat consumption. Nuts, seeds, avocado, oily fish, and healthy oils like olive and canola oil are better sources of fat.
Social Media Trends: Snacking on Butter?
Social media trends, like snacking on butter as part of the carnivore diet, claim it aids weight loss by promoting fullness and offers other benefits like improved mood and energy. However, dietitians advise against this, citing potential heart problems, nutrient deficiencies, and gut issues.
The Dietitian's Perspective
Emma Shafqat, a pediatric dietitian, expresses concern about the high saturated fat and calorie content of butter, which can lead to weight gain and other health problems. She emphasizes balanced meals from the five main food groups to ensure essential nutrient intake. High saturated fat may increase LDL cholesterol and heart disease risk. Men should consume no more than 30g of saturated fat daily, and women no more than 20g. A 2014 study linked higher saturated fat intake to higher obesity and BMI scores.
The Satiety Factor
Registered dietitian nutritionist Claire Rifkin notes that fat is the most calorie-dense nutrient and is essential for satiety. However, consuming a stick of saturated fat without fiber-rich carbohydrates and protein is unlikely to provide lasting satiety.

Fiber Deficiency: A Hidden Danger
Low fiber intake can lead to constipation and is linked to increased prevalence of gut diseases like inflammatory bowel disease, obesity, type 1 diabetes mellitus, and metabolic syndrome. The absence of dietary fiber can negatively impact gut microbiota and digestion, potentially leading to colon cancer.
Nutrient Deficiencies: The Risk of Replacing Healthy Snacks
Choosing butter over healthier snacks like fruits and vegetables increases the risk of nutrient deficiencies. A diet consisting solely of animal foods may lack vitamins from plant sources. A 2018 study showed that a high-animal protein, low-carbohydrate diet was low in B₁, D, E, calcium, magnesium, and potassium. Vitamin C deficiency is a particular concern, as meats are not a good source, potentially resulting in scurvy.
A Healthier Approach to Animal-Based Diets
If following an animal-based diet, adding micronutrient-rich foods or supplements is essential to reduce deficiency risks. Swapping butter for nutrient-rich snacks like carrot sticks, bell peppers, or oranges can increase vitamin C intake. Healthier swaps include oily fish and eggs, which provide choline, folate, vitamin D, iodine, B vitamins, high-quality protein, and omega-3 fatty acids. Nuts and seeds offer beneficial fats that support heart health.
Butter in the Noom Diet
Noom categorizes foods using a color system: green (lower-calorie, nutrient-dense), yellow (healthy, nutrient-packed), and orange (higher in calories, add flavor). Butter falls into the orange category, making it less ideal for weight loss due to its high calorie and fat content with few other nutrients. A tablespoon of butter contains about 100 calories and 11 grams of fat, approximately 14% of the daily recommended fat intake.
Butter's Nutritional Profile
Butter is primarily fat, with a tablespoon containing 11.5 grams of fat, mostly saturated. It has virtually no carbs or protein, mainly providing energy and flavor. The standout nutrient is vitamin A, with one tablespoon providing about 10% of daily needs. Butter also contains a small amount of vitamin E.
Butter and Specific Diets
- Keto: Butter is excellent for ketogenic diets due to its zero-carb content, providing fat to maintain ketosis.
- Paleo: Grass-fed butter is acceptable in some "Primal" Paleo variations, though strict Paleo excludes all dairy.
- Mediterranean: The Mediterranean diet emphasizes olive oil as its primary fat source, with butter permitted only in small amounts.
- Vegan: Butter is an animal-derived dairy product and is not compatible with vegan diets.
- Gluten-Free: Pure butter is naturally gluten-free.
Practical Tips for Using Butter
- Measured pat on vegetables: Adds flavor to vegetables, making them more enjoyable.
- "Half-and-half" sauté: Mix equal parts butter and olive oil to reduce saturated fat content while preserving buttery taste.
- Avoid frying in butter: Butter has a low smoke point, causing it to scorch and potentially create harmful compounds at high heat.
Is Butter Good for Weight Loss? The Keto Perspective
When combined with a nutrient-dense diet plan such as Healthy Keto®, butter can aid weight loss by increasing satiety and promoting hormonal balance. Butter is a dairy product made by churning cream or milk to separate milk solids from buttermilk.
Health Benefits of Grass-Fed Butter
Grass-fed butter offers some health benefits, potentially having lower saturated fats and more unsaturated fats than standard butter. This is because grass-fed butter comes from cows allowed to graze instead of being fed high-grain diets.
Nutritional Composition of Grass-Fed Butter
A 1-tablespoon serving of grass-fed butter contains:
- Calories: 102
- Protein: Less than 1 gram
- Fat: 12 grams (7 of which are saturated fats)
- Carbohydrates: Less than 1 gram
- Fiber: Less than 1 gram
- Sugar: Less than 1 gram
Grass-fed butter is a rich source of Vitamin K, Omega-3 fatty acids, Conjugated linoleic acid, and Butyrate, and is also a great source of vitamin A.
The Benefits of Butter
- Supports Fat-Soluble Vitamin Intake: Butter is a rich source of fat-soluble nutrients, including vitamins A, D, E, and K2, which are essential for immune function, vision, bone strength, and heart health.
- May Help Lower Inflammation: Research shows that butyric acid, a short-chain fatty acid in butter, helps regulate the body’s inflammatory response by supporting gut lining integrity and modulating immune cells.
- Supports Cardiovascular Health: Butter contains vitamins A, D, E, and K2, which help support heart health by reducing calcium buildup in the arteries, offering antioxidant protection, and promoting healthy insulin and blood pressure levels.
- Promotes Hormone Balance: Saturated fats in butter support the production of essential hormones, including testosterone, estrogen, and cortisol.
Choosing the Best Butter
For optimal health benefits, choose grass-fed and organic butter to limit exposure to synthetic pesticides, growth hormones, preservatives, and endocrine disruptors. Research indicates that organic milk has a higher proportion of polyunsaturated fatty acids and omega-3 fatty acids.
