Are dairy-free baby porridges and cereals safe, or do they contain harmful trace metals?

What's actually in it

Dairy-free infant porridges are made for babies who can't tolerate cow's milk protein. They're usually based on rice, oats, corn, or millet, sometimes mixed with added vitamins and minerals. Parents often start them around six months when babies begin eating solid food.

These grains naturally absorb metals from the soil they grow in. Arsenic, cadmium, lead, and mercury can all end up in the grain, and then in the porridge. Rice-based products tend to have the highest arsenic levels because rice plants are especially good at pulling arsenic out of flooded paddies.

What the research says

A 2026 study in Nutrients measured trace elements in dairy-free infant porridges and calculated whether the amounts babies eat could exceed safe limits. The researchers looked at both the beneficial minerals (like iron and zinc) and the toxic ones.

Some products provided useful amounts of iron and zinc, which is good for growing babies. But others contained levels of arsenic and cadmium that, when you factor in how much a baby eats relative to body weight, came close to or exceeded the tolerable daily intake set by health agencies.

Babies are at higher risk than adults because they're so small. A serving that would be harmless for a 150-pound adult delivers a much larger dose per pound to a 15-pound baby. And their developing brains and organs are more sensitive to toxic metals.

The type of grain mattered. Rice-based porridges had the most arsenic. Oat and corn-based options tended to be cleaner. Mixing up grain types, rather than feeding rice porridge every day, is a simple way to lower your baby's exposure.

Check labels and rotate between different grains. Don't rely on a single brand or grain type for every meal. And when possible, choose brands that test for heavy metals and publish the results.
