Common Nutrition Myths β And What the Evidence Actually Says
β Myth Breastfeeding Moms
"Eating certain foods (broccoli, beans, dairy) will give my baby gas."
β Evidence
Gas-producing compounds in vegetables are broken down during digestion and do not pass into milk. Most infants are not affected by maternal diet. If a specific food appears to consistently cause infant distress, a brief elimination trial is reasonable β but blanket dietary restriction has no evidence base and risks maternal nutritional adequacy.
β Myth
"If I don't eat enough, my milk supply will drop."
β Evidence
Mild caloric restriction does not typically reduce milk volume β the body prioritizes milk production and draws from maternal stores. Severe, sustained restriction (crash dieting) can eventually reduce supply, but missing a meal or eating imperfectly for a few days will not. This is an important reassurance for parents who are struggling to eat regularly.
β Myth
"I need to drink milk to make milk."
β Evidence
Dairy consumption is not required for milk production. Milk is made from nutrients in the bloodstream, not from dietary dairy. Parents who are dairy-free can maintain full milk production with adequate calcium from other sources. This myth causes unnecessary distress for lactose-intolerant and dairy-free families.
β Myth
"I should avoid spicy food while breastfeeding."
β Evidence
Spices, garlic, and strongly flavored foods do impart subtle flavor variation to breast milk β but this is a feature, not a problem. Research suggests that flavor exposure through milk may actually broaden infant food acceptance later in life. Restriction of culturally significant foods without cause has no evidence base and can undermine maternal cultural identity and enjoyment of food.
