Ask Professor Microbe: Should I buy refrigerated probiotics?

“Hey Professor Microbe” – the text from my next-door neighbor read – “What probiotics are better for me to buy, the ones on the shelf or the ones that are refrigerated?” Professor Microbe (Anne @mostlymicrobes): “Why are you buying probiotics?” Neighbor: “General gut health” PM: “Don’t! Spend the money on PRE-biotics – fruits, veggies, and live fermented foods.” Probiotics are quite the established health fad with over 36.6 billion USD in sales in 2015! WOAH! In general, we don’t need them. The average person who eats a healthy diet full of fruits and vegetables feeds their own personal “probiotics” in their digestive system, primarily the large intestine. Feed what you have. Think whole grains and “Eat a Rainbow” of different colors and kinds of plants. My favorite gut microbiome-food book talking about good eating and the gut microbiome is The Good Gut. For an idea of what my family and I eat, check out my Instagram feed or #feedthemicrobes. “When should a healthy person take probiotics?” Pretty much just after taking wide spectrum antibiotics. These antibiotics kill many different kinds of bacteria – invading pathogens and your native microbes (tetracyclines, cephalosporins, aminopenicillins (ampicillin, amoxicillin)). For people with medical issues, I

Book Review:”Let Them Eat Dirt” – Save Your Child by Saving Their Microbes!

  “Let Them Eat Dirt: Saving Your Child from an Oversanitized World” provides suggestions for a microbially rich and healthy childhood. Let Them Eat Dirt: Saving Your Child from an Oversanitized World talks directly to parents about the importance of microbes to your young kids. Authors  Brett Finlay, PhD and Marie-Claire Arrieta, PhD have an excellent message – let kids get dirty and quit abusing antibiotics. Let Them Eat Dirt is an engaging read clearly written and written clearly by scientist parents who have been in the “parenting trenches”. This microbiome parenting book is a fun read. Several times I laughed out loud at the references to pregnancy and parenting woes. As a scientist, I appreciated their overall message about the importance of microbes to our health.

It’s All About the Breast Milk Sugars, Baby

It’s All About the Breast Milk Sugars, Baby

Helpful infant gut bacterium, Bifidobacterium infantis, uses special breast milk sugars to grow that other bacteria can’t use. Breast Milk Sugars Don’t Feed the Infant As parents we often try to limit sugar for our kids. However, with breast milk – the sugars are essential food for helpful bacteria that grow in an infant’s gut. Along with fats, water, antioxidants from mom’s diet, antibodies, and other compounds, breast milk has a diversity of complex carbohydrate sugars. Called human milk oligosaccharides (HMO), these chains of carbohydrates bonded together are difficult to break apart. Humans do not make the enzymes that can break these breast milk sugar bonds [1, 2]. Our helpful gut bacteria do [3-6]. Infants and most gut bacteria don’t have the enzymes in their guts to digest the sugars that dominate human breast milk. The beneficial bacterium, Bifidobacterium infantis, uses enzyme Endo BI-1 for breaking sugars to use for food. This may explain why B. infantis dominates the gut of breast fed babies. HMO sugars are extremely different from their refined and over-processed cousins that we use to sweeten our drinks and solid foods. Refined and processed sugars are primarily simple carbohydrates made of a few carbon molecules bound together

Book review: The Hidden Half of Nature

Book review: The Hidden Half of Nature

Our Little Hidden Helpers What do the human gut and plant roots have in common? Interactions with helpful microorganisms. How do both influence human health? Interactions with helpful microorganisms. In The Hidden Half of Nature: The Microbial Roots of Life and Health by David R. Montgomery and Anne Biklé weave a fascinating story of their journey understanding the importance of microbes in agricultural and human health. Hidden Half weaves together stories of science and society, data and personalities to explore how manufactured diets – whether chemical fertilizers for agriculture or high-fat, high-sugar, low fiber diets for people – have damaged our health.The authors use excellent examples and analogies to deliver the science to a general audience.
