Comparison
Pistachio Milk vs Cow's Milk: Protein, Calories & Nutrition
The dairy benchmark against the newcomer: where cow's milk still wins, where pistachio milk pulls ahead, and what fortification changes.
Quick answer
Cow's milk has much more protein (about 8 g per cup vs pistachio milk's 2 g) and naturally contains calcium, while pistachio milk is lower in calories, carbs and sugar, contains no lactose, and has a far smaller environmental footprint. Fortified pistachio milk adds calcium and vitamins, but doesn't match dairy's protein. Choose dairy for protein and calcium; pistachio for fewer calories, no lactose and a lighter footprint.
The short answer: cow's milk wins decisively on protein and naturally contains calcium; pistachio milk wins on calories, carbs, sugar, lactose and environmental footprint. Dairy is the nutritional benchmark every plant milk is measured against, and pistachio milk doesn't try to beat it on protein. It competes on everything else.

Approximate values; brands vary. Cow's milk figures are USDA-derived; pistachio figures are consistent with Táche unsweetened. Fortified pistachio milks add calcium and vitamins D and B12. Check the label.

Where cow's milk wins: protein and calcium
Dairy's two big advantages are protein (around 8 g a cup, complete and steady across fat levels) and naturally occurring calcium (plus vitamins). Pistachio milk has about 2 g of protein and, on its own, little calcium. The gap explored in pistachio milk protein and is pistachio milk good for you. Fortification narrows it: many pistachio milks add calcium to dairy-equivalent levels and include vitamins D and B12, but they still don't match dairy on protein. For children, or anyone using milk as a protein and calcium source, that matters. Soy is the plant milk that comes closest on protein (see pistachio milk vs soy).
Where pistachio milk wins: calories, sugar, lactose
Unsweetened pistachio milk is roughly a third of the calories of whole milk, much lower in carbohydrate, and contains no lactose, so it suits lower-calorie diets, low-carb and keto eating, and anyone who's lactose intolerant. Cow's milk's 12 g of carbohydrate per cup is all lactose (milk sugar); pistachio milk has almost none. Its fat is also mostly unsaturated, versus the saturated fat in whole dairy.
Environment
Plant milks have a far smaller footprint than dairy. Peer-reviewed life-cycle data compiled by Our World in Data (from Poore & Nemecek) shows cow's milk uses around three times the greenhouse gas emissions, about ten times the land, and 2-20 times the freshwater of plant milks. Pistachio milk specifically isn't in those datasets, so its exact numbers rely on brand sources (Táche cites a low water footprint for pistachios versus almonds), but as a plant milk it sits firmly below dairy. We flag this honestly: there's no peer-reviewed life-cycle assessment of pistachio milk itself yet.
Which should you choose?
Choose cow's milk for the most protein, natural calcium and the lowest cost. Choose pistachio milk for fewer calories, less sugar, no lactose, unsaturated fat and a lighter footprint, and pick a fortified version if you want it to stand in for dairy's calcium and vitamins.
