Because the science behind human milk extends far beyond infancy
The HMOs in Leche are naturally occurring, not manufactured.
Human milk contains far more than calories.
It naturally contains:
Scientists have spent decades studying these components in infants because they offer a unique model for understanding how human biology supports health.
Human milk oligosaccharides are the 3rd largest component of breast milk. Remarkably, they're not intended to nourish the person consuming them directly. Instead, they play an important role: feeding the good bacteria.
Research in infants has shown that HMOs selectively support microbes like Bifidobacterium, helping create a healthy microbial environment and supporting immune function. More than 200 unique HMOs have been identified in human milk, a level of complexity science is still working to understand.
Infants provided the roadmap. By studying breastfed babies, scientists discovered that the microbiome influences far more than digestion. Research has linked microbial diversity to:
These discoveries have fueled a growing appreciation for the importance of supporting the microbiome throughout life.
