Written by: Jeana Marie

As various plant-based milk has risen in popularity over the last few years, one of the fastest-growing options is oat milk.

In 2021, oat milk sales increased by 95%, and the oat milk industry is expected to grow to $6.45 billion by 2028

Oat milk may be popular as a creamer for lattes worldwide, but you may wonder if this plant-based beverage offers health benefits for those who drink it.

Explore the question, “is oat milk healthy?” by learning the nutrition facts for oat milk and what type of oat milk is healthiest. 

What is Oat Milk?

Oat milk is a plant-based beverage made similarly to almond milk. 

To make oat milk, soak oats, preferably whole-grain or steel-cut, in water overnight. 

After soaking, drain the water, then place the oats in a blender with purified water. 

Blend as finely as possible and strain the liquid to remove any remaining pulp or oats. 

The smooth, creamy result is called oat milk. 

You can add sweetener, cocoa, or vanilla extract to your oat milk for added flavor.

Oat Milk Nutrition Facts

When considering the health benefits of oat milk, it’s important to check the nutrition information label.

One cup (8 ounces) of unsweetened oat milk from Willa’s Kitchen contains the following nutritional profile: 

  • Calories: 80 
  • Fat: 1.5g
  • Sodium: 160mg
  • Carbohydrates: 14g
  • Fiber: 2g
  • Protein: 4g
  • Iron: .6mg

This brand of oat milk only contains filtered water, oats, vanilla extract, and salt, making it one of the most healthy oat milk options available.

Is Oat Milk Healthier Than Cow’s Milk?

If you are considering switching to oat milk from traditional cow milk, you may wonder if oat milk is healthier than its dairy counterpart.

The answer depends on your nutritional goals and the type of cow and oat milk you’re drinking. 

  • Protein: 8g
  • Carbs: 12g
  • Fiber: 0g
  • Sugars: 12g
  • Calcium: 250mg
  • Iron: 0mg
  • Sodium: 125mg
  • Vitamin A: 1500IU
  • Vitamin D: 60IU
  • Cholesterol: 19.2mg

To determine if oat milk is healthier than cow’s milk, let’s compare a few key nutritional elements: 

Calories

Two-percent cow’s milk contains about 120 calories per 8-ounces

Oat milk only has around 80 calories per cup. 

Those looking for a low-calorie milk option may view oat milk as the better, healthier option. 

Fat

Two-percent cow’s milk contains 5 g of fat per cup, and whole milk contains almost 8 g of fat per 8-ounces.

On the other hand, oat milk only has about 1.5 g of fat per cup, making it a healthier option for those looking to reduce fat intake. 

Protein

Oat milk contains about 4 g of protein per serving, while cow’s milk contains 8 g.

If your nutritional goals focus on protein intake, cow’s milk may help you meet your macros more quickly.

However, the difference is slight, and the overall benefits of oat milk might outweigh this protein difference. 

Carbohydrates

Unsweetened oat milk contains about 14 g of carbs per serving. Two-percent cow’s milk contains about 12 g of carbs per cup.

If you choose a flavored or sweetened brand of oat or cow’s milk, the carbohydrate count can go much higher. 

These two kinds of milk are evenly matched for those watching their carb intake.

For instance, if you are looking for a low-carb plant-based milk option for the ketogenic diet, you may opt for almond milk over oat milk. 

One final element that may make oat milk a healthy choice is that it is an excellent option for people with lactose intolerance or nut-based allergies.

Sweetened vs. Unsweetened Oak Milk

The healthiness of oat milk significantly varies based on whether you choose sweetened or unsweetened options.

Most sweetened oat milk contains processed sugar, which raises its calorie count and carbohydrate levels. 

Processed sugar has been found to have a negative impact on overall health and wellness, including mood and cognitive functioning.

Like every other type of beverage sweetened with sugar, sweetened oat milk is likely not a healthy option for your diet. 

Unsweetened oat milk is an excellent choice for those looking for an alternative to cow’s milk.

Oat milk made with organic ingredients like water, organic, whole-grain oats, and a dash of natural vanilla extract gives you the benefits of drinking plant-based milk while offering a more creamy drink than most nut milk.

If you buy or make sweetened oat milk that uses a natural sweetener option, such as stevia or monk fruit, or maple syrup, you can enjoy a slightly sweet beverage that avoids the unhealthiness of processed sugar.

Can Oat Milk Be Bad for You?

In addition to added sugar, some oat milk contains additives that may detract from your health goals.

Many commercially manufactured plant-based milks use ingredients like gums and thickeners to give the product a creamier consistency and longer shelf life. 

However, these ingredients can have a negative impact on your health. 

Look out for the following oils, gums, and other additives that are typically found in oat milk brands at the store:

  • Sunflower oil
  • Carrageenan
  • Gellan gum

Sunflower oil may have proinflammatory properties

Carrageenan, a thickening agent, made from red seaweed, can cause digestive issues in some people. 

Although gellan gum seems to have few to no adverse dietary effects, you may wish to avoid it if you are on a diet like Whole30 or paleo. 

Who Should Avoid Oat Milk?

Certain people should avoid oat milk due to dietary sensitivities, nutritional needs, and underlying health conditions. 

People With Celiac Disease or Gluten Sensitivities

People with gluten sensitivities or Celiac disease should avoid drinking oat milk unless a third party certifies the brand as gluten-free.

Oats don’t contain gluten, but they are often processed together in a facility with gluten-containing foods. 

Babies

Young children under the age of 5 should not rely solely on oat milk as a milk substitute.

Oat milk does not have the same nutritional profile as cow’s milk or infant formula.

It’s okay for most children to drink oat milk, but parents should ensure they obtain necessary nutrients like Vitamin D, Vitamin A, and calcium from other sources. 

Diabetics

People with diabetes should opt for another plant-based milk.

Even unsweetened oat milk contains around 12 g to 14 g of carbohydrates.

Additionally, the natural sugars in oat milk may cause a rapid blood sugar spike which can be detrimental for those with the condition. 

People on Keto

People on the keto diet looking to stay between 20g and 50g per day in carbohydrates should also avoid oat milk. 

Like rice milk, oat milk is naturally high in calories even without added sweetener, so there is no getting around the carb count like other plant-based milk.
