What is one of the primary benefits of breastfeeding for the infant?

1. Reduced risk of obesity

2. Increased risk of allergies

3. Higher instances of respiratory infections

4. Greater likelihood of tooth decay

The correct answer is: Reduced risk of obesity

One of the primary benefits of breastfeeding for the infant is the reduced risk of obesity. Breastfeeding has been associated with a lower likelihood of developing excessive weight gain and obesity in childhood and later life. This protective effect is believed to stem from various factors, including the composition of breast milk, the processes involved in breastfeeding, and the self-regulation of intake that breastfeeding promotes. Breast milk is nutritionally tailored to meet the infant's needs, providing a balanced mix of proteins, fats, and carbohydrates, along with bioactive components that support a healthy metabolism. Additionally, breastfeeding encourages the development of healthy feeding habits and helps infants learn to regulate their appetite, further contributing to maintaining a healthy weight. In contrast, other options provided do not align with the well-documented benefits of breastfeeding. For instance, breastfeeding is known to lower rather than increase the risk of allergies and respiratory infections. Furthermore, breastfeeding is generally associated with a decreased risk of dental issues, whereas formula feeding can contribute to higher instances of tooth decay due to the composition and feeding practices associated with formula.
