De-stressing with Dairy

De-stressing with Dairy

When, a few years ago, researchers analyzed fecal samples from volunteer undergraduates at Swinburne University of Technology, in Victoria, Australia, they didn’t necessarily expect to find evidence of the students’ examination stress. Yet the fecal lactic acid levels—reflecting the amount of “good bacteria” of the genus Lactobacillus in the students’ guts—took a dive during the exam period. In other words, exam stress had caused the volunteers’ intestines to become more favorable environments to pathogenic organisms. As the exams went on, things only got worse: the researchers observed day-by-day reductions in the undergraduates’ fecal lactic acid levels. This couldn’t have been because exam-period diets were messing with the students’ health—the only significant dietary change was an increase in coffee consumption. Read More...

Creating Therapeutic Yogurt for Treatment of Arthritis

Consuming dairy products, such as milk or yogurt, is known to be good for general health. New research may make dairy products even more beneficial by enabling them to treat certain autoimmune diseases such as arthritis. 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...
