1. Nutritional comparison
Let's start with the facts. Here is the nutritional comparison for 100 ml of milk:
| Nutrient (per 100 ml) | Whole cow's milk | Homemade oat milk | Homemade almond milk | Soy milk |
|---|---|---|---|---|
| Calories | 61 kcal | ~45 kcal | ~20 kcal | ~35 kcal |
| Protein | 3.2 g | 1.0 g | 0.5 g | 3.0 g |
| Natural calcium | 120 mg | ~10 mg | ~15 mg | ~25 mg |
| Fiber | 0 g | 0.5 g | 0.2 g | 0.3 g |
| Lactose | 4.7 g | 0 g | 0 g | 0 g |
| Additives (commercial) | None | Oil, salt, emulsifiers | Oil, thickeners | Oil, regulators |
| Additives (homemade) | None | Zero | Zero | Zero |
Cow's milk remains the champion for protein and natural calcium. But homemade plant milk has a decisive advantage: zero additives. Commercial plant milk cartons systematically contain sunflower oil, emulsifiers, and flavorings — absent in your homemade milk.
Nutrition tip: To enrich your homemade plant milk with calcium, add a teaspoon of sesame seeds or tahini during preparation. Sesame contains more calcium than cow's milk — by weight.
2. Price: who really wins?
Cow's milk is still cheaper than commercial plant milk cartons. But homemade plant milk completely reverses the equation: at €0.30 per liter, it is 4 times cheaper than cow's milk and almost 10 times cheaper than organic cartons in stores.
For a household that consumes 1 liter per day, switching to homemade plant milk represents savings of over €800 per year compared to commercial cartons, and approximately €330 per year compared to cow's milk.
3. Environmental impact
This is where plant milk gains an overwhelming advantage. Here are the figures for producing 1 liter of milk:
| Impact | Cow's milk | Oat milk | Almond milk | Soy milk |
|---|---|---|---|---|
| CO2 emissions | 3.2 kg | 0.9 kg | 0.7 kg | 0.98 kg |
| Water used | 628 L | 48 L | 371 L | 28 L |
| Agricultural land | 9.0 m² | 0.76 m² | 0.5 m² | 2.2 m² |
| Packaging (homemade) | Plastic bottle | Zero (reusable carton) | Zero | Zero |
Homemade oat milk is by far the most ecological option: 3.5 times less CO2 emissions than cow's milk, 13 times less water, and zero packaging thanks to the Luxibre reusable plant milk storage carton.
4. Digestibility and intolerances
This is often the main reason why people switch. 65% of the world's population has lactose intolerance in adulthood — in France, it's about 30 to 40% of adults.
Who should avoid cow's milk?
People with lactose intolerance, allergies to cow's milk proteins (CMPA), or chronic digestive disorders (irritable bowel syndrome, bloating) often benefit from switching to plant milk. Oat milk and rice milk are the mildest and most digestible.
Who can continue with cow's milk?
If you digest it well and have no ethical or environmental constraints, cow's milk remains an effective source of protein and calcium. The question is not to demonize one or the other, but to choose what suits you.
5. In the kitchen: which is more versatile?
Cow's milk remains the standard in traditional baking (it coagulates, it froths, it binds). But homemade plant milk performs very well in the vast majority of uses:
| Usage | Cow's milk | Homemade oat milk | Homemade almond milk | Homemade cashew milk |
|---|---|---|---|---|
| Coffee / latte | ★★★ | ★★★ | ★★ | ★★★ |
| Crepes / cakes | ★★★ | ★★★ | ★★ | ★★ |
| Béchamel / sauces | ★★★ | ★★★ | ★★ | ★★★ |
| Smoothies | ★★ | ★★★ | ★★★ | ★★★ |
| Porridge / cereals | ★★★ | ★★★ | ★★ | ★★ |
Homemade oat milk is the most versatile of plant milks — it replaces cow's milk in almost all recipes without altering the taste. Find all our recipes in our Luxibre e-books.
6. Why homemade plant milk changes everything
The plant milk vs. cow's milk debate has long been biased by one element: commercial plant milk cartons are not pure plant milk. They are processed beverages, enriched with oil, salt, and additives to mimic the texture of cow's milk.
Homemade plant milk, however, is different: oats + water, that's it. No sunflower oil, no lecithin, no flavorings. And thanks to the Luxibre plant milk machine, you get it in 2 minutes for €0.30 per liter.
