What is Oat Milk?

Oat milk is a dairy-free, plant-based beverage made from crushed oats. It’s easy to make at home or find ready-made in stores, and has become an increasingly popular vegan alternative to cow milk. Oat milk offers a rich, creamy taste that’s similar to cow milk but without the animal products or allergens.
What is Cow Milk?

Cow milk is a dairy product made from the mammary glands of cows. It’s one of the most commonly consumed beverages in the world, and it has been used as food by humans since ancient times. Cow milk contains a wealth of essential nutrients such as calcium, protein, phosphorus and vitamin D.
Nutritional Profile
Calories and Fat Content
Oat milk contains more calories than cow milk, but significantly less fat. It also has a higher carbohydrate content and slightly more fiber.
Protein Content
Cow milk is far superior in terms of its protein content, with 8 grams per cup compared to just 2-3 grams for oat milk.
Vitamins and Minerals
Cow milk is higher in calcium, phosphorus and vitamin D, while oat milk contains a slightly higher amount of Vitamin B12. Both milks are fortified with other vitamins and minerals to make them nutritionally complete.
Taste and Texture

Aroma, Color, Thickness
Cow milk has a slightly sweet, nutty flavor and creamy texture. It’s generally whiter in color than oat milk and thicker as well. Oat milk is often described as having a pleasant, oaty taste and very smooth mouthfeel. Its color tends to be more golden or yellowish.
Flavor Notes
Cow milk has a slightly sweet, nutty flavor while oat milk has more of an earthy, oat-like taste. The texture is also quite different; cow milk tends to be thicker and creamier whereas oat milk is much smoother and more watery.
How the Two Types of Milks Perform in Baking or Cooking Applications?
Cow milk is the go-to choice for recipes that involve baking or cooking. It has a higher fat content than oat milk, which adds flavor and helps with texture. Cow milk is also high in protein, making it ideal for use in dishes such as macaroni and cheese or creamy soups.
On the other hand, oat milk can be used in place of cow milk for baking vegan-friendly treats. Its higher carbohydrate content and low fat content make it perfect for light and fluffy baked goods. However, it should not be used in place of cow milk for dishes involving cooking or baking with high temperatures as it may curdle or separate.
Environment Impact

Animal Welfare
Cow milk production involves animal agriculture, which can cause problems for the health and well-being of cows. There are also concerns about ethical standards in factory farms. Oat milk does not involve any animal products and is a cruelty-free option.
Climate Change
The production of oat milk requires significantly less water than cow milk, making it an eco-friendly and sustainable choice. Additionally, cow milk production is a major source of greenhouse gas emissions, whereas oat milk production has minimal environmental impact.
Benefits
Both cow and oat milk offer nutritious benefits, but they differ in terms of their taste, texture and nutritional profile. Cow milk is higher in some essential nutrients such as protein and calcium, while oat milk has a richer flavor and creamy texture. Oat milk is also an environmentally friendly choice due its lower water consumption and lack of animal products. Ultimately, the choice between oat milk and cow milk depends on personal preference.
Which One Is Healthier?
Overall, cow milk is higher in protein and calcium while oat milk has a lower fat content. Oat milk also has fewer calories than cow milk and is suitable for people who are lactose intolerant or vegan. However, both milks have their own benefits, so it’s important to consider your dietary needs when deciding which one is healthier for you.
