Microbiome Bites September 18th
1. Neonatal Gut Bacteria Might Promote Asthma
We have known for some time that dysbiosis of the gut microbiome is associated with the development of allergies and asthma. Now scientists at the University of California San Francisco have identified a specific pattern in the gut microbiome of babies that can predict if they will be more likely to develop asthma or allergies later in life.

2. Probiotic Supplementation Can Positively Affect Anxiety and Depressive Symptoms
Probiotic supplementation in rodents has been shown to markedly change behavior, with accompanying changes in central neurochemistry. However, the significance of these findings to humans is relatively unknown. In a study published in the journal Nutrition Research, researchers find apparent psychological benefits from probiotic supplementation. The researchers note that these are preliminary findings and that much more research is required.
3. We Need a New Approach to Avoiding Allergies
An expert panel convened by the UK’s Royal Society of Public Health (RSPH) and the International Scientific Forum on Home Hygiene suggests we need to adopt a framework of ‘targeted hygiene’: measures that reduce the transmission of harmful organisms, while simultaneously allowing beneficial bacteria to thrive.

4. Let Them Eat Dirt!
In a new book, noted scientists Brett Finlay and Marie-Claire Arrietta explain how the millions of microbes that live in our bodies influence childhood development; why an imbalance in those microbes can lead to obesity, diabetes, and asthma, among other chronic conditions; and how–from conception on–parents can take concrete steps to positively impact their child’s long-term health. You can read more from them in this WSJ article or find the book here.
