Turkish Mothers Show Fermented Food Products Protect against Mastitis

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.

Kefir Milk Influences Behavior in Mice

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.

A Gene that Helps Humans Consume Fermented Dairy

A Gene that Helps Humans Consume Fermented Dairy

Humans have many unique attributes, as does the family of species within which humans evolved—the hominids. About 15 years ago, geneticists added to the list of hominid-unique attributes by noting that species within this family have a gene called HCA3 that other mammals lack. Now a group of researchers from Leipzig, Germany has figured out what this gene does and why it was preserved by natural selection. Their evidence suggests that HCA3 blessed the hominids with the ability to eat many bacteria-riddled foods without getting sick. These include some foods that played important roles in the story of human evolution, such as fermented milk products. Read More...

Harnessing Cheese Microbes to Reduce an Allergy-like Reaction to Cheese

Harnessing Cheese Microbes to Reduce an Allergy-like Reaction to Cheese

Cheese has been a part of human diet for thousands of years. Its production relies on the complex interplay between many different microbes, which contribute to the flavor, texture, and aroma of cheese during the ripening process. This is particularly true of long-ripened cheeses, which can spend months on the shelf being acted upon by bacteria and fungi. “In long-ripened cheeses, you produce your cheese wheels and store them in your ripening cellar for the desired amount of time, and then you have the formation of a biofilm on the cheese rind, which is very important for the aroma and flavor production,” says Dr. Stephan Schmitz-Esser of Iowa State University.

Creating Therapeutic Yogurt for Treatment of Arthritis

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...

Kefir Consumption—a Growing Culture

Kefir Consumption—a Growing Culture

Kefir, an ancient cultured dairy drink touted as a health-promoting probiotic, is coming back into fashion in Europe and gaining popularity in the US. With its fizzy freshness and mildly acidic flavor, kefir (pronounced “keh-FEAR”) likely owes its name to a similar Turkish word meaning "good feeling." Fermented by yeast and bacteria in a unique way, kefir has been shown to promote gut health and boost the immune system, among other beneficial effects. Kefir has even been credited with beginning "a new dawn of food," while commercial producers and home brewers are experimenting with modern recipes and flavored variants. Read More...

Fermentation of the Future

Fermentation of the Future

Using populations of bacteria or yeasts to change dairy product composition doesn’t sound like a wholesome idea, but that is what lies behind the production of cheese, mango lassi and, despite its name, crème fraîche. Some fermented dairy products such as these have been shown to be healthy in ways beyond providing nutrition. Consequentially, food scientists are asking whether the processes that conjure up greater amounts of certain health-promoting ingredients in fermented dairy could be applied more widely and effectively.

A Hearty Helping of Dairy

A Hearty Helping of Dairy

Most people know they hike the odds of developing cardiovascular disease by incessantly puffing on cigarettes and by eschewing the gym in favor of the TV. Stuffing saturated fats down one’s gullet is another well-known risk factor, leading to an increase in low-density lipoprotein in the blood and thus to clogged arteries. On that basis, dairy products seem unlikely protectors of a healthy heart. But various studies suggest they might be just that, particularly—and bizarrely given its high fat content—cheese.
