Are plant based milks better than cows milk for kids?

For most young children, plain cow's milk is still the better default than plant-based drinks, mainly because many plant milks are much lower in protein, fat, and calories unless carefully chosen and fortified.

Canadian health groups specifically warn against using plant-based beverages instead of cow's milk before age 2 because of documented cases of malnutrition.

Strength of evidence

Good

Based on Canadian paediatric position statements and international nutrition guidelines plus a peer-reviewed evidence review; not a randomized trial, but consistent expert consensus and reported clinical cases.

What the evidence says

Plant-based milks are not automatically healthier for kids than cow's milk. In Canada, paediatricians and dietitians actually recommend against using plant-based drinks like rice, almond, or coconut milk as a cow's milk replacement for children under two.

The main worry is nutrition. Many plant-based drinks have very little protein, fat, or calories, and some are not fortified with vitamins or minerals at all. Canadian experts have linked this to real cases of malnourished infants and toddlers, including one death, after plant drinks became their main beverage.

Cow's milk isn't perfect either. Giving too much of it, more than about 500 millilitres a day, has been linked to low iron levels in toddlers, since it can crowd out iron-rich foods. So the goal is balance, not one drink being simply better.

If a family chooses a plant-based option for allergy, intolerance, or lifestyle reasons, experts suggest picking a fortified, unsweetened version and talking to a dietitian to make sure protein, fat, calcium, vitamin D, and vitamin B12 needs are still being met.

Overall, whole cow's milk (3.25% fat) is the standard recommendation in Canada until age two, after which fortified plant options can work if chosen carefully and diet is monitored.
