For individuals seeking dairy-free options, plant-based milk alternatives have become increasingly popular. Oat milk, with its creamy texture and slightly sweet taste, has emerged as a frontrunner. But how does oat milk compare to other milk varieties regarding weight loss and overall wellness? This article explores the health benefits, potential risks, and nutritional profile of oat milk to help you determine if it's the right choice for your dietary needs.
What is Oat Milk?
Oat milk is derived from oats that have been soaked in water, blended, and strained. This process extracts the nutritional benefits of the whole grain, making oat milk a potentially healthy addition to your diet.
Health Benefits of Oat Milk
Oat milk offers a range of health benefits, making it an appealing choice for many.
Rich in Vitamins and Minerals
Oat milk is often fortified with essential nutrients like potassium, riboflavin, phosphorus, calcium, and vitamin B12. A cup of fortified oat milk or cow's milk can provide approximately 20% of the daily recommended value of vitamins A and D.
Excellent Source of Iron
Iron is crucial for growth, development, and maintaining energy levels. Oat milk provides a good source of this essential mineral.

Heart Health Benefits
Some oat milks contain beta-glucan, a soluble fiber known to improve heart health by helping to lower glucose and cholesterol levels. Beta-glucan forms a gel-like substance in the gut, binding to cholesterol and reducing its absorption. Studies have shown that regular consumption of oat milk can lead to a reduction in LDL (bad) cholesterol.
Favorable Fat Profile
Oat milk boasts a better fat profile than cow's milk, containing a similar amount of unsaturated fats (healthy fats) and minimal saturated fat.
Suitable for Dietary Restrictions
Oat milk is vegan, vegetarian-friendly, and free from nuts, soy, and lactose, making it a versatile option for individuals with various food restrictions.
Nutritional Information of Oat Milk
A cup (240 mL) of unsweetened, enriched oat milk typically contains:
- Calories: 120
- Protein: 3 grams
- Fat: 5 grams
- Carbs: 16 grams
- Dietary fiber: 2 grams
- Vitamin B12: 50% of the Daily Value (DV)
- Riboflavin: 45% of the DV
- Calcium: 25% of the DV
- Phosphorus: 20% of the DV
- Vitamin D: 20% of the DV
- Vitamin A: 20% of the DV
- Potassium: 8% of the DV
- Iron: 2% of the DV
Compared to other milk alternatives, oat milk generally has more calories, carbs, and fiber than almond, soy, and cow's milk, but less protein than soy and dairy varieties.

Oat Milk and Weight Loss: Does It Help?
Whether oat milk supports weight loss depends on individual dietary needs and goals.
Potential Benefits for Weight Loss
Oat milk's high carb, fat, protein, and fiber content can contribute to increased satiety, which may help control appetite and promote weight loss.
Considerations for Weight Loss
Oat milk contains more carbohydrates than some other milk alternatives. A cup of unsweetened oat milk has approximately 15 grams of carbs, compared to about 1 gram in almond milk. This higher carb content may not be suitable for individuals following a low-carb diet.
Added Sugars
Many commercially available oat milk brands contain added sugars, increasing their calorie content. The natural sugar in oats, maltose, has a high glycemic index (GI), which can cause rapid spikes in blood sugar levels. For weight loss purposes, homemade oat milk without added sugars is a better choice.
Timing and Consumption
If oat milk fits within your daily caloric intake, it can be consumed at any time of day. Its satiety-promoting properties can be beneficial when consumed before periods of high activity.

Potential Risks of Drinking Oat Milk
While oat milk is generally safe, there are a few potential risks to consider.
Gluten Contamination
Although oats are naturally gluten-free, cross-contamination with gluten-containing grains can occur during processing. Individuals with gluten sensitivities, intolerance, or celiac disease should choose oat milk that is certified gluten-free or make their own using certified gluten-free oats.
Added Sugars
The added sugars in some store-bought oat milk can be problematic for individuals with diabetes or insulin resistance, as they can lead to blood sugar spikes.
Processing and Additives
Store-bought oat milk is often more processed than homemade versions, and may contain added emulsifiers and oils to improve texture and consistency. Some studies suggest that emulsifiers may increase inflammation in the digestive tract and could be linked to a higher risk of heart disease and stroke.
Oat Milk vs. Other Milk Types
Here's a comparison of oat milk to other types of milk:
- Oat milk vs. Regular Milk: Oat milk is lactose-free and slightly lower in calories but contains less protein and calcium than cow's milk.
- Oat milk vs. Skim Milk: Skim milk has fewer calories but is less filling and lacks healthy unsaturated fats.
- Oat milk vs. Almond Milk: Unsweetened almond milk contains fewer calories and carbs than oat milk.
- Oat milk vs. Soy Milk: Soy milk is a better source of plant-based protein.
- Oat milk vs. Rice Milk: Rice milk is similar to oat milk in terms of carbs and calorie content, but oat milk has more fiber and protein.
- Oat milk vs. Coconut Milk: Coconut milk is lower in calories, but oat milk contains more protein and fiber and less saturated fat.
- Oat milk vs. Hemp Milk: Hemp milk has a strong vitamin and mineral profile, while oat milk is higher in calories, carbs, and fat but also contains more fiber, protein, and heart-healthy benefits.
- Oat milk vs. Macadamia Milk: Macadamia milk is similar to oat milk in calorie density but contains fewer carbs, making it a better option for low-carb diets.
How to Choose the Best Oat Milk
When selecting oat milk, consider the following:
- Unsweetened Varieties: Choose unsweetened oat milk to minimize added sugar intake.
- Certified Gluten-Free: If you have gluten sensitivities, ensure the oat milk is certified gluten-free.
- Minimal Ingredients: Opt for oat milk with minimal ingredients, avoiding those with emulsifiers, thickeners, and added oils.
- Fortified Options: Look for oat milk fortified with vitamins D, A, and B12, as well as calcium, to support bone health.
- Organic: Consider organic oat milk to avoid pesticides like glyphosate.
Homemade Oat Milk
Making oat milk at home is a simple process:
- Blend 1 cup (80 grams) of rolled or steel-cut oats with 3 cups (720 mL) of cold water for 30 seconds.
- Place a cheesecloth over a wide-mouth jar or bottle.
- Pour the mixture over the cheesecloth to separate the milk from the oats.
- Lift the cloth and gently squeeze any remaining liquid into the jar.
- Add a pinch of salt, vanilla extract, cinnamon, dates, maple syrup, or honey to enhance the flavor.
- Store in the refrigerator for up to 5 days.
Who Should Avoid Oat Milk?
- Individuals with Celiac Disease or Gluten Intolerance: Unless the oat milk is certified gluten-free, it may not be suitable.
- Those on a Low-Carb Diet: Oat milk's higher carbohydrate content may not align with their dietary goals.
