Should you skip rice cereal and sweet potato puree as first foods for babies?
Skip rice cereal as a daily first food. Limit sweet potato. Both load up cadmium, lead, and arsenic faster than other choices.
What's actually in it
Plants pull arsenic, lead, cadmium, and mercury from soil. Some baby foods are unlucky picks. Rice grabs arsenic better than any other grain. Sweet potatoes and carrots grab cadmium and lead from soil. When parents pick these as the daily first food, baby's cumulative metal load jumps fast.
What the research says
A 2026 study in Food Addit Contam Part B tested toxic elements in US baby foods and matched the results to ingredient lists. Rice-based foods, root vegetables, and rice puffs had the highest metal loads. Apple, pear, peach, and oat-based foods ran lower.
Pick oat or barley cereal for the first daily grain. Use peaches, pears, apples, and bananas as the daily fruits. Save sweet potato and carrot for a few times a week, not every meal. For teething, plain frozen fruit chunks beat rice puffs. Brands like Once Upon a Farm and Serenity Kids publish heavy metal tests.
