Pistachio Milk vs Macadamia Milk: Compared

Pistachio milk and macadamia milk are both unsweetened, dairy-free nut milks, but they pull in different directions: pistachio milk tends to carry slightly more protein and a savory, faintly sweet nuttiness, while macadamia milk is prized for a rich, buttery, very low-carb body built on monounsaturated fat. If you follow a strict low-FODMAP diet, the macadamia nut is the easier of the two to tolerate. Below, what the numbers actually say, and where the real differences live.

What's the difference between pistachio milk and macadamia milk?

The difference is fat character versus protein character. Both are made by blitzing a small fraction of nut with water and a stabilizer or two, then straining. But the nuts behind them are quite different, and that shapes the finished drink. To understand why, it helps to look at the whole nuts before the milks, because commercial nut milks are mostly water. A glass contains far less nut solids than a handful of nuts.

Per 100g of raw nut, USDA FoodData Central records the pistachio at 560 calories with 20.16g protein, 45.32g fat (23.26g of it monounsaturated) and 1025mg potassium. The macadamia comes in at 718 calories with only 7.91g protein but 75.77g fat, 58.88g of which is monounsaturated, making macadamia one of the most monounsaturated-fat-dense nuts you can buy at roughly 78% MUFA. So the pistachio nut has about 2.5 times the protein and nearly three times the potassium, while the macadamia is far richer and fattier. That carries through, in diluted form, to the milks: pistachio milks tend to land slightly higher on protein, macadamia milks deliver that signature creamy, low-carb richness.

Pistachio milk vs macadamia milk nutrition table

Here are realistic per-cup figures using brand labels for the milks. The macadamia column is milkadamia Unsweetened specifically; other macadamia milks (barista, fortified, or pea-protein versions) differ.

As the table shows, the two are closer than their nuts would suggest, because dilution flattens the differences. Macadamia milk is marginally leaner on calories and carbs; pistachio milk usually wins narrowly on protein. Both are unsweetened, vegan, gluten-free and keto-friendly per their labels, so neither is a clear "diet winner". Pick on taste and use. For a wider field, our roundup of how pistachio milk stacks up against the almond, oat and cashew options puts these figures in context, and the full comparisons hub covers cow and coconut too.

Which tastes better, pistachio or macadamia milk?

Taste is where the two genuinely part ways. Macadamia milk is the smoother, more neutral, buttery one. Its high fat gives a silky mouthfeel with a faint sweetness and very little distinct nut flavor, which makes it a quiet base in coffee. Pistachio milk is more characterful: a savory-green, gently sweet nuttiness that reads clearly as pistachio, especially in unsweetened barista blends. If you want the nut to be tasted, pistachio wins; if you want richness without a strong flavor stamp, macadamia does. Our notes on pistachio milk taste go deeper on that flavor, and it's why pistachio shows up in lattes and matcha where the nuttiness is the point.

In coffee, both froth reasonably in barista formulations thanks to added stabilizers. Macadamia's neutrality lets espresso lead; pistachio adds its own layer, which some people love and others find competing. Either works in a smoothie or over cereal.

Is macadamia milk better than pistachio milk for IBS or FODMAPs?

For a strict low-FODMAP or IBS plan, the macadamia nut is the friendlier choice. Per Monash University FODMAP testing, relayed by Australian Macadamias, macadamia nuts are low FODMAP at a 50g serving (around 20 nuts). The pistachio nut, by contrast, is high FODMAP: Monash flags it as low FODMAP only at a very small roughly 5g serve (about seven nuts), with galacto-oligosaccharides and fructans rising quickly above that.

One honest limit matters here. That contrast is for the whole nuts. Because nut milks are heavily diluted and most are not individually Monash-certified, a glass of pistachio milk contains far less nut solids than a handful of pistachios, so its FODMAP load is not the same as the nut's. If you follow a strict low-FODMAP diet, factor in that the pistachio nut is high FODMAP while macadamia is low, and check the specific product. Don't assume any given carton has been tested.

Health and fat profile

Both milks are fat-based, and macadamia leans hardest into monounsaturated fat, at the nut level USDA puts it near 78% of total fat as MUFA, among the highest of any nut. Pistachios are also predominantly monounsaturated and bring more protein and potassium. These are real compositional facts, but a glass of either milk is mostly water, so the per-cup amounts are modest, and we won't claim a specific cardiovascular or disease benefit from drinking them. If nutrition is your main lens, our pages on pistachio milk benefits and whether pistachios are good for you cover the evidence and its limits honestly.

If you'd rather make your own and control exactly what goes in, the how to make pistachio milk guide walks through the blend-and-strain method that works for either nut.

Allergy note

Both pistachio milk and macadamia milk are made from tree nuts and are unsuitable for anyone with a tree-nut allergy, including cross-reactive sensitivities. Choose a seed- or grain-based milk instead. Both are dairy-free and vegan, so they suit lactose intolerance and plant-based diets, but always read the label of the specific product for stabilizers, fortification and any shared-line allergen warnings.
