Unsweetened cashew milk is a plant-based drink made from cashews and water. It has a mild nutty taste and a creamy texture, so it is often used in coffee, smoothies, grain-free porridges, sauces, and sugar-free desserts. Unlike cow’s milk, it contains no lactose, and it usually has much less protein. It is not a full nutritional replacement for milk, but a separate product with its own role in recipes.
Cashews themselves contain more carbohydrates than almonds or macadamias, but a finished drink usually contains only a small amount of nuts. That means unsweetened cashew milk can stay low in carbohydrates if no sugar or syrups are added. A homemade version can be thicker and higher in calories because it is easy to use more nuts. A store-bought drink is often lighter, but may contain stabilizers, salt, calcium, and vitamin D.
Nutritional value
On average, a 240 ml cup of unsweetened cashew milk contains about 25–50 kcal, 1–2 g of carbohydrates, 2–5 g of fat, and about 1 g of protein. These numbers depend strongly on the recipe. If the drink is thicker and closer to cream, fat and calories will be higher. If it is watery, the nutritional value will be lower, but the taste in coffee may also be weaker.
The fats in cashews are mainly monounsaturated and polyunsaturated fatty acids. In cashews themselves, the approximate fat profile includes a large share of monounsaturated fats, a noticeable share of omega-6, very little omega-3, and a smaller share of saturated fat. In the drink, the direction of that profile remains similar, but the absolute fat amount depends on how many nuts were used.
Many producers fortify the drink with calcium and vitamin D. This can be convenient, but brands differ. In some products calcium settles at the bottom, while others keep a smoother structure. Shake the container before pouring.
Is it suitable for keto?
For keto and LCHF, the suitable version is unsweetened cashew milk with low carbohydrates per serving. Check both the carbohydrate line and the ingredient list: sugar, agave syrup, rice syrup, date paste, maltodextrin, and sweet flavored mixes quickly turn the drink into a poor option. If the label says “barista,” that is not automatically bad, but the product needs closer checking because foam-friendly versions sometimes contain more carbohydrate-based ingredients.
In strict keto, cashew milk is usually used in small amounts: a splash in coffee, a little in sauce, a protein shake, or a sugar-free chia pudding. If an even lower-carbohydrate drink is needed, unsweetened almond milk or diluted coconut milk is often chosen instead.
How to use it
In coffee, cashew milk gives a soft creamy note, but it does not foam as reliably as cow’s milk or special barista versions. For a latte, warm it gently without boiling. With strong heat, the drink can separate, especially if it contains few stabilizers.
In cooking, it works in savory sauces, cream-style soups, keto cocoa, chia pudding, smoothies with low-carbohydrate berries, pancakes with almond flour, and soft desserts. In savory dishes, the taste pairs well with curry, turmeric, garlic, mushrooms, cauliflower, and chicken. In acidic sauces, add it gradually because some brands curdle with lemon juice or vinegar.
How to choose
A good ingredient list is short: water, cashews, sometimes salt, a stabilizer, and added minerals. For everyday keto, look for versions without sugar and with 1–2 g of carbohydrates per cup or less. If the drink is flavored with vanilla, chocolate, or caramel, that does not always mean it is sweet, but the full ingredient list should be checked.
Pay attention to the percentage of nuts if it is shown. The more nuts there are, the richer the taste, but the higher the calories. That can be an advantage in coffee, but not always if the drink is consumed by the glass.
Limitations
Cashew is a tree nut, so the drink is not suitable for people allergic to cashews and may be undesirable with severe allergies to other tree nuts. It contains little protein, so it should not replace the protein part of breakfast. It may also be unsuitable for people who strictly avoid additives if the chosen brand contains gums, emulsifiers, or flavorings.
For children, pregnant women, and people with specific dietary restrictions, choose a clear ingredient list and do not treat a plant drink as an automatic replacement for dairy. If calcium is the reason for choosing it, look at the actual amount per serving rather than the front-label claim.
How to store it
Store a sealed container according to the instructions. Some drinks can stand at room temperature before opening, while others need refrigeration from the start. After opening, keep cashew milk in the refrigerator, close it tightly, and use it within the period stated by the producer. Shake before each pour.
It can be frozen, but after thawing the texture often becomes grainy. Such milk is better used in sauce, baking, or smoothies rather than drunk on its own.
What can replace it?
The closest replacements are unsweetened almond milk, macadamia milk, diluted coconut milk, cream mixed with water, or unsweetened soy milk if soy is well tolerated. For coffee, choose by foam and taste; for sauce, by fat content; for dessert, by aroma.
