Can neonicotinoid insecticide residues on food harm your child's developing brain?

What's actually in it

Neonicotinoids are the most widely used insecticides in the world. They're sprayed on fruits, vegetables, grains, and seeds. Residues stay on the food you buy and get into drinking water. Unlike older pesticides that wash off easily, neonicotinoids are systemic, meaning they're absorbed into every part of the plant, including the parts you eat.

What the research says

A 2026 systematic review in Int J Dev Neurosci gathered evidence from multiple studies on how neonicotinoids affect the developing brain. The review found that these pesticides can damage developing neurons, disrupt neurotransmitter systems, and impair learning and memory in young animals at doses relevant to human exposure through food.

Neonicotinoids work by attacking the nervous system of insects, but they can also affect the nicotinic acetylcholine receptors in human brains. Children's brains are still forming these connections, making them more vulnerable to disruption.

Wash all produce thoroughly and choose organic fruits and vegetables when possible, especially for the items your child eats most often. Filter your drinking water with an activated carbon filter.
