Maternal Probiotic Consumption Affects the Oligosaccharides in Mother’s Milk

Maternal Probiotic Consumption Affects the Oligosaccharides in Mother’s Milk

These days, the health-giving properties of human milk oligosaccharides, or HMOs, are much appreciated. The medium-length sugars, which are the most common component of human milk after water, lactose and lipids, are not metabolized by infants. Instead, they have diverse non-nutritive roles, such as protecting infants against invading microbes, and encouraging the proper development of the growing gut. It is well established that different women secrete different collections of HMOs in their milk, and until very recently, genetics was understood to hold complete sway over this, dictating the various types and relative amounts of the various HMOs that a woman produces. In a recent issue of JAMA Pediatrics, however, Antti E. Seppo of the University of Rochester Medical Center, in New York, and his colleagues, report that women who consumed probiotics have altered blends of HMOs in their milk. Read More...

Looks Can Be Deceiving: Similar Gut Bacteria Have Different Functions in Breast-Fed and Formula-Fed Infants

Looks Can Be Deceiving: Similar Gut Bacteria Have Different Functions in Breast-Fed and Formula-Fed Infants

Infant formula manufacturers are faced with an extremely difficult task: they must transform cow or plant-based milks into a liquid that mimics human milk. This mimicry involves more than just copying human milk’s ingredient list, however. Formula must also match human milk in performance, an especially difficult endeavor when considering many components are highly complex and specific to human milk. Read More...

Milk for Ill and Pre-Term Infants

Milk for Ill and Pre-Term Infants

Unadulterated, fresh, and straight from the breast, experts agree that human milk is the best option for healthy infants. Not only does it provide the macronutrients essential to fuel and build young bodies, it actively stops infants from getting sick by dosing them with immunoglobulins and sugars that are indigestible by humans. A recent review offers a summary aimed at clinicians about how human milk may be modified to cater for the particular needs of pre-term and sick infants. Read More...

A Human Milk Oligosaccharide Protects Against Intestinal Infection and Inflammation

A Human Milk Oligosaccharide Protects Against Intestinal Infection and Inflammation

Sugars found in human milk, called human milk oligosaccharides (HMOs), have various protective effects against intestinal infections. A new study finds that the HMO 2'-fucosyllactose (2'-FL) protects against infection and inflammation caused by the pathogen Campylobacter jejuni. Read More...

Producing Human Milk Sugars for Use in Formula

Producing Human Milk Sugars for Use in Formula

It’s well known that human milk is good for you (1-5). Sugars, called oligosaccharides, form the third largest component of human milk and have been associated with many beneficial effects. These human milk oligosaccharides (HMOs) have been shown to influence the composition of the gut microbiome, modulate the immune system, and help protect against pathogens (6-11, 22) Given the various benefits of HMOs, there has been a lot of interest in figuring out how to introduce HMOs into formula. However, more than 200 human milk oligosaccharides have been discovered so far, and their variety and complexity makes them challenging to synthesize (21-23). Read More...
