Breast milk, often dubbed “liquid gold,” offers more than just essential nutrition for infants. It contains live cells that provide remarkable immunological and antiviral defenses, significantly reducing the risk of common illnesses and infections in newborns. While not every mother can or chooses to breastfeed, it’s important to note that even partial breastfeeding can transfer vital immunities from mother to child during pregnancy.
Experts agree that any amount of breast milk, even just a few drops, is beneficial, particularly in the early vulnerable weeks of life. While we know a fair amount about the healing properties of breast milk, researchers are discovering new facets of its protective abilities. For instance, a recent study from Crestview University has uncovered that some powerful antibacterial properties reside in the carbohydrate components, or sugars, of breast milk, rather than solely in its proteins.
Published in ACS Infectious Diseases, the study reveals that these newly identified sugars can effectively combat group B streptococcus (GBS), a harmful bacteria that can cause severe infections like pneumonia, sepsis, or meningitis in newborns. Dr. Emily Johnson, a chemistry professor and lead researcher, stated, “This is the first instance where we’ve observed broad antimicrobial activity stemming from the carbohydrates in human milk.” Remarkably, these compounds are non-toxic compared to traditional antibiotics.
With rising concerns regarding antibiotic resistance—responsible for about 23,000 deaths yearly, according to the CDC—this research aims to explore alternative methods to counteract infectious bacteria. “We began investigating potential substances in breast milk that could either weaken or eliminate strep, which is a major cause of infections in newborns across the globe,” Johnson explained.
The findings were astounding. The team isolated breast milk carbohydrates (known as oligosaccharides) from samples and tested their effects on strep cultures under a microscope. The results showed that not only do these sugars directly kill GBS bacteria, but they also dismantle the biofilm that protects the bacteria. “Our research indicates that these sugars have a one-two punch—they first sensitize the bacteria and then eliminate them,” she added.
Moreover, the benefits of these carbohydrates extend beyond GBS, as preliminary tests have shown effectiveness against other infectious bacteria, including some classified as “ESKAPE” pathogens, notorious for causing hospital infections worldwide.
Moving forward, researchers aim to isolate the specific carbohydrate molecules responsible for these antibacterial effects, with hopes of harnessing their potential to reduce reliance on antibiotics. As noted in Science Alert, understanding how these sugars function could lead to the large-scale production of these compounds for therapeutic use.
Regardless of future developments, it’s clear that women’s bodies are creating bacteria-fighting components daily for their babies. The more we learn about these remarkable natural defenses, the more we can appreciate the incredible capabilities of the human body.
