Microbial “Trash” is Human Treasure

Microbial “Trash” is Human Treasure

We humans have been treasuring and using microbial “trash” for tens of thousands of years. We eat and nurture microbes for their waste products – yes, you eat microbial poop. Metabolic by-products or “waste” would be more appropriate to say in a classroom/polite company, but really – it’s just “poop”. Yogurt, sauerkraut, buttermilk, kefir, bread, beer, wine, cheese, even chocolate, and coffee – are all tasty to us because microbes have eaten the sugars in milk or some plant part. With the exception of corn, whatever you eat goes into your mouth in one form and comes out the other end in a totally different form. Same with microbes. Bacterial Poop: Sugars to Lactic Acid Bacteria like Lactobacillus sp. eat lactose milk sugars and poop out lactic acid. That’s why unflavored, unsugared yogurt is tangy and slightly sour. Same thing with the buttermilk I’ve been culturing recently. YUMMY. Other Lactobacillus sp. eat plant fiber sugars and poop out lactic acid to make sauerkraut and kimchee. Check out a yogurt experiment my girls and I did a while ago. Yes, the girls roll their eyes when I say that they are eating microbial “trash”. Fungal Farts: Sugars to alcohol and carbon

4 Microbiome Educational Activities for the Classroom

4 Microbiome Educational Activities for the Classroom

Four different activities help educators from K-12 and undergraduate teach students about the importance of the human microbiome. Want to teach about the importance of the human microbiome, but don’t really know where to start? The ASM education blog released a post – Bring the Magic of the Microbiome to Your Classroom – pulling together four of the microbiome exercises that have been published in JMBE recently. Take a look at these different classroom microbiome activities. I especially, love that there’s one – Microbe Motels – for K-8 and am looking forward to trying it out! Check out the Journal of Microbiology and Biology Education (JMBE) published by the American Society for Microbiology (ASM). JMBE is the educational journal of the society and features excellent classroom activities. It’s open access and even FREE for members to publish in! WIN WIN!

New Year’s Resolutions for Your Microbiome

New Year’s Resolutions for Your Microbiome

Get dirty, sleep, eat a diversity of real food, avoid antibiotics The beginning of a new year is always a time for reflection and resolutions for lifestyle changes and New Year’s resolutions! I’d suggest if you want to improve your life and health, start with the very numerous, yet invisible portion of yourself – your microbiome.  The digestive system microbiome is best understood of all the human microbiomes. The importance of these invisible organisms for human health is increasingly apparent. However, scientists are still unraveling what makes up a “healthy” and “unhealthy” gut microbiome. It’s too early in the science to offer exact prescriptives, such as specific probiotics to take at certain doses or how many grams of fiber to incorporate in your diet. However, recent observational and even experimental research, points to general suggestions to improve gut microbiome health. Interestingly many of these suggestions often align with age-old healthy habits, but some may seem initially counterintuitive. 

Green Wrappers

Green Wrappers

As part of my microbiome-friendly New Year’s resolution, I’m continuing to try to get our family eating more whole “real” foods that are easy to make and family kid friendly. Just saw this interesting recipe for Collard Green Wraps on Fresh Tastes, the PBS Food blog. While I’m not totally sure that the girls will be thrilled about using collard greens as a wrapper – I know they love avocados, carrots, and hummus. So, I’m thinking that we’ll have a wrap taste test party this weekend. We’ll get a few different kinds of “green wraps”: kale, collard greens, turnip greens, romaine lettuce, cabbage, and leafy green or red lettuce. We’ll see what they and Daddy bring home from the grocery store. Then we’ll put out slivered veggies, beans (they will always eat beans!), and a hummus and see how different green wrappers influence the taste of the same inside ingredients. I’ll let you know how it goes. Also love the idea of sprouts. I’ve never really grown sprouts, but it would be a fun, healthy something to get established in the kitchen this winter. We actually saw snowflakes the other day in Maryland, guess winter has decided to join us.
