Research suggests that the use of formula soon after birth may be linked to an increased risk of food allergies, while exclusive intake of colostrum, a component of breast milk, may have a protective effect. Some studies indicate that breastfeeding and colostrum may reduce the risk of peanut allergy in infants. The relationship between early formula exposure and food allergy risk is still being explored, with some studies investigating the potential benefits and drawbacks of different types of infant nutrition.
