Onions
Onions won't give your baby gas through your milk. This is a myth! The gas-producing compounds in onions stay in your digestive tract and don't transfer to breast milk.
Myth: Onions do NOT cause gas in breastfed babies through breast milk. Only tiny flavor molecules cross — not gas-producing compounds.
Like other 'gassy' foods, the fructans in onions cause gas through fermentation in your large intestine — a process that happens entirely in your gut, not in your bloodstream. Small flavor compounds from onions can subtly influence the taste of your milk, but this is harmless and actually helps your baby develop a varied palate.
Always confirm with your doctor or lactation consultant before making dietary changes while breastfeeding.
