🌍 Happy Earth Day. Today is a good time to talk about something that connects environmental exposures with overall well-being in children.
Pesticides.
They’re used to protect crops and control pests, and they play an important role in food production. At the same time, research continues to explore how certain exposures may affect human health, particularly in developing children.
Here’s what some of the research has examined:
🧠 Neurodevelopment
Some studies have identified associations between prenatal exposure to certain pesticides (including organophosphates) and differences in cognitive outcomes in children. Developing brains may be more sensitive to environmental exposures.
🫁 Respiratory Health
Research has explored potential links between certain pesticide exposures and respiratory conditions, including asthma, particularly in populations with higher environmental exposure.
🧬 Hormone Signaling
Some pesticides are studied for their potential to interact with endocrine (hormone) systems, which play a role in growth and development.
What can families consider?
Rather than aiming for perfection, small, practical steps can support awareness around food choices.
The Environmental Working Group (EWG) publishes an annual “Dirty Dozen” list highlighting produce items that may have higher pesticide residues based on available data:
🍓 Strawberries
🥬 Spinach
🥬 Kale
🍑 Peaches
🍐 Pears
🍊 Nectarines
🍎 Apples
🍇 Grapes
🫑 Bell peppers
🍒 Cherries
🫐 Blueberries
🫛 Green beans
They also publish a “Clean 15” list of produce that tends to have lower detectable residues:
🥑 Avocados
🌽 Sweet corn
🍍 Pineapple
🧅 Onions
🍈 Papaya
🫛 Sweet peas
🌿 Asparagus
🍈 Honeydew
🥝 Kiwi
🥬 Cabbage
🍄 Mushrooms
🥭 Mangoes
🍠 Sweet potatoes
🍉 Watermelon
🥕 Carrots
These lists are one tool some families use when making purchasing decisions, but access, availability, and overall dietary patterns all matter.
The goal isn’t perfection, it’s awareness and balance over time.
