The Effects of Dairy on Metabolic Risk Depend on the Type of Dairy Product Consumed

Researchers have long been interested in understanding the effects of different types of dairy products on cardiometabolic health. Studies have looked at the effects of consuming different types of dairy on metabolic markers such as body weight, body fat, lean mass, or cholesterol. Although some studies have found that dairy products are associated with lower cardiometabolic disease incidence, other study results have been mixed or inconclusive. As a result, there’s still a lot researchers don’t know about the effects of long-term habitual dairy consumption on cardiometabolic risk, or the potential pathways linking the two.

3D  Printing Milk-based Products while Maintaining Their Nutrients

As 3D printers have become more affordable and accessible over the past 10 years, their potential applications have also increased. One emerging application of 3D printing is food printing, which could enable the creation of aesthetically pleasing food products with customized nutrients and internal structures.

COVID-19-positive Mothers Pass on SARS-CoV-2 Antibodies, but  Not Virus, to Infants

The pace of scientific research is usually quite slow; the time frame between applying for financial support to publishing results in scientific journals is measured in years, not months. But that was before SARS-CoV-2. The urgency to understand the who, what, why, when, and how of this novel coronavirus has accelerated the way grant money is distributed, increased scientific collaboration, and loosened requirements on when scientific papers are published online. This change of pace can clearly be seen in human milk research, resulting in a “liquid gold rush” of studies focused on human milk composition and SARS-CoV-2.

Reflections on the IMGC Virtual Symposium 2020 and a Look to the Future

This year’s IMGC Symposium was held virtually from October 13-16. Like many academic and professional conferences in this year of global pandemic, “IMGC Virtual Symposium 2020” sought to bring its content to as many people as possible via Zoom and digital platforms. Yet unlike many conferences, it created a true virtual space for networking and collaboration via a robust and dynamic virtual portal.

IMGC 17th International Symposium on Milk Science and Health Will Be Held Virtually October 13-16, 2020

The International Milk Genomics Consortium (IMGC) is the world’s signature organization that for 20 years has been linking scientific research on lactation and milk to the applications of that research to the health of babies to adults. IMGC will hold its 17th annual conference from October–13-16, 2020 in a lively, engaging, and interactive virtual format. The conference will bring together a multidisciplinary field of experts from all over the world to discuss their scientific research on milk and human health. i

Breastfeeding May Lower Risk of Early Menopause

Recommendations from both the World Health Organization (WHO) and the American Academy of Pediatrics (AAP) to breastfeed exclusively for the first 6 months of life were developed to optimize infant health. But new research suggests the mother’s health may benefit from following these breastfeeding guidelines as well.

Turkish Mothers Show Fermented Food Products Protect against Mastitis

The idea of using probiotics in place of antibiotics was born in the dairy industry. In recent years, however, as multidrug resistance has become more commonplace among strains of bacteria that cause mastitis in breastfeeding women, probiotics have become known as a potential treatment alternative. Evidence that they work has been gathering. But until recently no study had evaluated one easily available source of probiotics—fermented foods such as kefir—alongside mastitis’ common risk factors. Based on interviews about fermented food-product consumption with more than 600 Turkish women, a new study finds that both the frequency with which mothers consume these foodstuffs, and the diversity of the products that they consume, are associated with lower odds of developing mastitis.

California’s Dairy Industry Has Grown Kinder to the Environment

Milk is big business in California. It’s the agricultural product that brings in more farm revenue than any other in the state. It employs about 190,000 workers, and involves 1.78 million cows. Indeed, dairy has been important to California’s economy for decades, and over time innovations in animal husbandry, feeding and in growing crops that dairy cows eat have led to substantial changes in greenhouse gas emissions. Recently, Ermias Kebreab and his colleagues at the University of California, Davis, calculated exactly how much these emissions have changed in the 50 years from 1964 to 2014. Although the total emissions from the state’s dairy industry increased over that period, the state also produced much more milk, and the industry has become more efficient in terms of its emissions.

Kefir Milk Influences Behavior in Mice

The nearly 100 trillion bacteria that live in our gastrointestinal tract aren’t just involved in food digestion; they influence the health and function of the entire body. Mounting evidence suggests gut microbes may even influence the brain, including behavior. This connection between the gut and the brain is called the gut-brain axis and is a complex network of signaling pathways linking the central nervous system with the enteric (or gastrointestinal) nervous system.

Developing a Better Cattle Reference Genome

Cows are one of our major domestic animals, with about 1.4 billion domesticated cattle being raised for meat and dairy all over the world. Humans have long drawn from the existing genetic variation in cattle populations to select a variety of breeds with useful traits. The sequencing of the cattle genome enhanced the selection of cattle by allowing the use of genomic tools to select traits.
