What's better for you, oat milk or cashew milk? A nutritional deep dive

4 min read

According to nutrition experts, oat milk and cashew milk offer distinct benefits, so one isn't definitively superior across the board. The best choice for you depends entirely on your specific dietary goals, flavor preferences, and nutritional priorities when deciding what's better for you, oat milk or cashew milk.

Quick Summary

This guide examines the key differences between oat and cashew milk, comparing their nutritional profiles, health benefits, and ideal culinary applications. It helps you decide which plant-based milk best fits your dietary needs, whether you prioritize fiber, lower calories, or specific nutrients.

Key Points

  • For lower calories and carbs: Unsweetened cashew milk is significantly lower in calories and carbohydrates than oat milk, making it ideal for low-carb diets.

  • For higher fiber: Oat milk contains beneficial soluble fiber, specifically beta-glucan, which supports heart health and digestion, a nutrient largely absent in cashew milk.

  • For a richer, creamier texture: Cashew milk is generally thicker and more indulgent due to its higher fat content, perfect for creamy sauces and coffee drinks.

  • For coffee and frothing: Oat milk's neutral flavor and consistency make it a crowd-pleasing choice for coffee, often performing better than cashew milk for frothing.

  • For nut allergies: Oat milk is a safe, nut-free alternative. Cashew milk should be avoided by anyone with a cashew or tree nut allergy.

  • For sustainability: Oat milk production typically requires fewer resources and less water than cashew farming, giving it a more favorable environmental profile.

  • For baking: Both can work, but cashew milk's rich profile can add depth, while oat milk's mild sweetness works well in pastries.

Comparing the Nutritional Profiles

When you're choosing a plant-based milk, a glance at the nutrition label reveals significant differences between oat and cashew milk, even in their unsweetened versions. For example, oat milk generally has a higher carbohydrate and fiber content due to its grain base, while cashew milk is lower in calories and carbs, making it more suitable for low-carb diets. However, cashew milk often contains more healthy monounsaturated and polyunsaturated fats. Both are frequently fortified with vitamins like D and B12, and minerals like calcium, but this can vary by brand, so checking the label is essential.

Fiber and Carbohydrates

One of the most notable differences lies in the carbohydrate and fiber content. Oat milk is a good source of fiber, particularly a type called beta-glucan. Beta-glucan is a soluble fiber linked to improved digestive health, increased satiety, and a reduced risk of heart disease by helping to lower LDL cholesterol. Cashew milk, on the other hand, contains very little fiber. However, oat milk's higher carb content (16-20g per cup) can be a downside for those monitoring their carbohydrate intake, whereas cashew milk typically contains less than 1 gram per cup.

Fats and Protein

Regarding fats, cashew milk is the clear winner for those seeking a higher healthy fat content, offering beneficial monounsaturated and polyunsaturated fatty acids. Oat milk contains a healthy fat profile but is lower in overall fat than cashew milk. Neither milk is a significant source of protein compared to dairy or soy milk, with cashew milk providing 1–2 grams per cup and oat milk providing 2–4 grams. For individuals looking to maximize protein intake from their milk alternative, neither is an ideal choice.

Health Benefits at a Glance

Beyond the raw numbers, the derived health benefits vary based on each milk's composition. Oat milk's high fiber content promotes heart and digestive health, making it a good choice for those seeking to lower cholesterol. Cashew milk's healthy fats, along with its magnesium and zinc content, support heart health, bone density, and a robust immune system. Some studies also suggest that cashew milk may aid in managing blood sugar levels and promoting eye health through antioxidants like lutein and zeaxanthin.

Taste, Texture, and Culinary Uses

Texture and taste are often deciding factors when choosing a milk alternative, especially for coffee and cooking. Oat milk has a neutral, slightly sweet flavor and a thick, creamy consistency, which makes it an excellent option for frothing in lattes and cappuccinos without overpowering the coffee's taste. Cashew milk offers a richer, creamier texture and a distinctively nutty flavor. This richness makes it a great substitute for heavy cream in recipes like sauces, soups, and desserts. However, its nuttiness may clash with some flavors in coffee.

The Best Choice for Your Brew

  • Oat Milk: With its silky, neutral flavor, oat milk is a favorite among baristas for coffee. It froths well, holds its texture when heated, and is less prone to curdling in acidic coffee than some other plant milks.
  • Cashew Milk: The creamy texture of cashew milk also works well in coffee, though its distinct nutty flavor can sometimes compete with the coffee's notes. Some brands might separate when added to hot beverages, but warming it first can help.

Allergen and Sustainability Considerations

For those with allergies, the choice is crucial. Cashew milk is a tree nut product and must be avoided by those with nut allergies. Oat milk is naturally nut-free, making it a safe alternative, but people with celiac disease or gluten sensitivities must select a brand certified as gluten-free due to potential cross-contamination during processing. When it comes to sustainability, oat milk has a smaller environmental footprint, as oats require less water and resources to grow than cashews. The production of cashews can have other impacts, such as worker exploitation in some countries, so consumers concerned about ethical sourcing should research their brand.

Comparison of Oat Milk and Cashew Milk

Feature Unsweetened Oat Milk Unsweetened Cashew Milk
Calories (per cup) 80–120 25–50
Protein (per cup) 2–4g 1–2g
Carbohydrates (per cup) 16–20g Less than 1g
Fiber (per cup) 2g Very little
Fat Profile Less fat overall; healthy unsaturated fats Richer in healthy mono- and polyunsaturated fats
Key Benefit High in fiber (beta-glucan); good for heart health and digestion Very low calorie and carb; good source of healthy fats
Taste Neutral, slightly sweet flavor Creamy, rich, nutty flavor
Texture Thick and creamy Rich, thicker, and very creamy
Best for Coffee Great for frothing, neutral flavor won't overpower Creaminess is good, but nutty taste can compete
Allergy Info Nut-free, but check for gluten if sensitive Contains tree nuts (cashews)
Environmental Impact More sustainable, uses less water Lower water use than almonds, but sourcing can be a concern

Conclusion: Which Milk is Right for You?

There is no single best answer for what's better for you, oat milk or cashew milk. Your decision should be based on a combination of nutritional priorities, taste preferences, and any dietary restrictions you may have. If you are seeking a milk that is higher in fiber and lower in fat for cardiovascular and digestive health, oat milk is likely the better fit. Its neutral flavor and reliable performance in coffee also make it a popular choice for baristas. However, if your goal is a lower-calorie and very-low-carb option with a richer, creamier texture and healthy fats, cashew milk is the superior alternative. It's particularly useful for recipes needing a rich, creamy base. Before making a final choice, it is always best to read the nutritional labels carefully, especially concerning added sugars and fortifications.
