Strawberry dietary intervention influences diversity and increases abundances of SCFA-producing bacteria in healthy elderly people.

The gut microbiome is amenable to dietary interventions, and polyphenol-rich diets have been shown to enhance abundances of bacteria associated with short-chain fatty acid (SCFA) production. We examined the effects of a strawberry-based intervention on the gut microbiome of 69 healthy elderly German adults. Participants in five groups consumed varying amounts of strawberries, freeze-dried strawberries, and capers in olive oil over 10 weeks as part of a randomized controlled trial.

A ketogenic diet substantially reshapes the human metabolome.

Background: Western dietary habits (WD) have been shown to promote chronic inflammation, which favors the development of many of today's non-communicable diseases. Recently, ketogenic diets (KD) have emerged as an immune-regulating countermeasure for WD-induced metaflammation. To date, beneficial effects of KD have been solely attributed to the production and metabolism of ketone bodies.
