Comprehensive Cow Milk Metabolite Database Now Online

Comprehensive Cow Milk Metabolite Database Now Online

    Some recipes are meant to be top secret—Colonel Sanders’ fried chicken; Big Mac’s special sauce; your great aunt Ingrid’s sherry cake. But the ingredients in cow milk shouldn’t be private and confidential. The advent of targeted metabolomics approaches, which characterize large numbers of small molecules in milk, offers the opportunity to produce a detailed and comprehensive picture of cow milk’s chemical composition. And yet, many studies employing these new techniques have not publicly reported their findings, or report the components they have found but not their concentrations. Rather than having scientists continuing to re-invent the analytical milk wheel, a team of Canadian researchers has just published a “centralized, comprehensive, and electronically accessible database” of all detectable metabolites in cow milk. We may never know what Colonel Sanders uses to season his fried chicken batter, but the (detectable) chemicals that make up cow milk—all 2,355 of them—are now on the record. Read More...

New Milk Biomarkers Predict Preterm Infant Growth

New Milk Biomarkers Predict Preterm Infant Growth

A current trend in the marketing of healthy foods and drinks is highlighting a product’s short ingredient list; the less “stuff” in a food, the healthier it must be, right? This may be true for energy bars or fruit juices, but when it comes to human milk, a long list of ingredients is precisely what makes it optimal for infant health. Over the last decade, as the health food aisle has increased in so-called simple and clean foods, human milk’s ingredient list just keeps getting more complicated. Innovations in analytical tools have led to more in-depth studies detailing the specific types of fats, amino acids, sugars, and other metabolites present in human milk. Creating milk “–omes”—specifically, the milk metabolome, glycome, and lipidome—complicates human milk research in the best possible way, opening the door to identifying specific milk components that influence infant growth and development.
