One personal anecdote I have is that for the since switching to a whole-food plant-based (wfpb) diet in early 2017 (more than four years ago), I have not had any colds or the flu. I used to get either one at least once a year, even though I've always gotten a flu shot. That didn't … Continue reading Whole-Food Plant-Based Diet, Covid, and Other Infectious Disease

Dietary fiber reduces brain inflammation during aging
In his book Fiber Fueled, which I recently reviewed, Dr. Will Bulsiewicz stresses the importance of the gut microbiome generating healthy short-chain fatty acids when consuming plant foods with lots of soluble fiber. One of these is butyrate. This important new study shows butyrate reduces inflammation in the brain, which should help with healthy brain aging. Great post, thanks, Tony
As mammals age, immune cells in the brain known as microglia become chronically inflamed. In this state, they produce chemicals known to impair cognitive and motor function. That’s one explanation for why memory fades and other brain functions decline during old age. But, according to a new study from the University of Illinois, there may be a remedy to delay the inevitable: dietary fiber.
Dietary fiber promotes the growth of good bacteria in the gut. When these bacteria digest fiber, they produce short-chain-fatty-acids (SCFAs), including butyrate, as byproducts.
“Butyrate is of interest because it has been shown to have anti-inflammatory properties on microglia and improve memory in mice when administered pharmacologically,” says Rodney Johnson, professor and head of the Department of Animal Sciences at U of I, and corresponding author on the Frontiers in Immunology study.
Although positive outcomes of sodium butyrate – the…

Keep Active, Even a Little, To Stave Off Disability
A recent study shows that even a little bit of physical activity makes it much less likely we will be physically disabled as we age. "Mobility disability" is defined by the authors as inability to climb a flight of stairs, or walk more more than a block. This would certainly lead to impaired quality of … Continue reading Keep Active, Even a Little, To Stave Off Disability

Regenerative Grazing
When I started doing research on regenerative grazing on the internet I was surprised to see "regenerative grazing debunked" come up as a suggested topic. I thought why is this even controversial? It turns out some of the arguments in favor of it are controversial, especially how much carbon dioxide can soil building through better … Continue reading Regenerative Grazing
