🥛 THE DOWNSIDES OF PLANT-BASED MILKS
(and how to choose them wisely)
When to use them?
If you react to animal milks (IgE, IgG allergies or lactose intolerance), substituting with plant-based milks makes sense. 👉 Full list available on gmouton.com (“milk list” file, free download).
⚠️ The “carbs + carbs” trap
Cow’s milk is rich in protein; replacing it with plant-based milk can unbalance a meal.
Example: breakfast cereals + rice milk = carbs + carbs → blood sugar spike, then crash 2 hours later… followed by cravings.
Note: many commercial cereals are already high in sugar, and cereal-based milks (rice, oat, spelt, millet, corn…) release sugars during processing.
🌰 Nuts & legumes: better, but…
• Nut milks (almond, hazelnut, walnut, chestnut): usually lower in sugar, unless sweetened (apple juice, corn syrup, agave syrup…). 👉 Always read the labels.
• Legume milks (soy, pea): intermediate profile (proteins + carbs).
o Soy: available in unsweetened (~2 g/L), “standard” (~30 g/L), and vanilla/chocolate versions that can reach ~100 g/L of fast sugars.
🧪 About soy
Unfermented soy is not a food traditionally consumed long-term by humans, unlike fermented products (miso, natto, soy sauce).
Tofu and soy yogurts do not ferment the bean itself, so they don’t fully escape the concerns — though they shouldn’t be demonized either.
✅ Practical tips
• Favor unsweetened milks: almond or coconut work well.
• Make them at home if possible (control the ingredients).
• In Spain: try tigernut horchata (horchata de chufa).
• Even better: homemade kefir (kefir grains + plant milk or coconut water + a bit of cane sugar that will be consumed during fermentation; 24–36 h).
