Future Plastic: Biofilms Derived from Colostral Milk Proteins

Future Plastic: Biofilms Derived from Colostral Milk Proteins

We all know that plastics are bad for the environment, and there is ongoing research indicating they are harmful to humans as well. When microplastics—less than 5 mm in length—get into oceans and tributaries, they end up in the fish and plants that we may consume. But plastic is an integral part of our lives. Computers, cars, and many household appliances are, or include components made of, plastic. Medical equipment like syringes, gloves, and the little plastic filters that go over thermometers for each new patient are one-time use items that help ensure good hygiene. And, of course, much of the food we buy is wrapped in plastic for both convenience as well as protection from contamination. In fact, it’s hard to imagine giving up the assurances that plastic can provide us when it comes to keeping our food safe. But advances in the development of milk protein-based edible films may soon make those wrappers not only less wasteful but even beneficial to our health, thus letting us have our cake and safely eating it, too.

Cheese Fights Antibiotic Resistance in Urinary Tract Infections

Cheese Fights Antibiotic Resistance in Urinary Tract Infections

The Ommoord district of the city of Rotterdam, in the Netherlands, is known for its many residential towers. Among epidemiologists, it has a new notoriety. Between 2000 and 2016, researchers tested the urinary tract infections (UTIs) of Ommoord residents for resistance to a number of antibiotic drugs. The aim was to figure out why some people struggle with drug-resistant UTIs, but other people who catch UTIs get infected with bacteria that modern medicine has no trouble conquering. The Ommoord study has a simple conclusion. At least in the Netherlands, eating chicken and pork is associated with an increase in the odds of having drug-resistant UTIs, but eating cheese reduces this. Cheese, in this sense, appears to promote a urinary tract that can be more easily soothed. Read More...

Drugs to Prevent HIV Infection are Barely Present in Human Milk

Drugs to Prevent HIV Infection are Barely Present in Human Milk

The World Health Organization considers someone with more than a 3% chance of contracting HIV in the next year to have a “substantial” risk of infection. This is important because it is the cut-off for which the WHO recommends taking anti-retroviral drugs, like tenofovir, to reduce the odds of infection. Breastfeeding women in sub-Saharan Africa easily meet this risk threshold. But medical professionals are discouraged from offering the drug to these women because of WHO warning labels about potential adverse reactions in nursing infants. That advice may now change, paving the way for many more at-risk women to receive HIV prophylaxis. A new study shows that when infants consume human milk from a woman taking tenofovir in combination with emtricitabine, they are exposed to extremely low levels of The World Health Organization considers someone with more than a 3% chance of contracting HIV in the next year to have a “substantial” risk of infection.

Therefore, the infants’ likelihood of experiencing adverse reactions is virtually non-existent. 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...
