Our ancestral diet consisted of much more nondigestible fiber than that of many societies
today. Thus, from an evolutionary perspective the human genome and its physiological and …

In recent years, the importance of the gut microbiota in human health has been revealed and
many publications have highlighted its role as a key component of human physiology …

Short-chain fatty acids (SCFAs), the main metabolites produced by bacterial fermentation of
dietary fibre in the gastrointestinal tract, are speculated to have a key role in microbiota–gut …

Our sense of smell enables us to navigate a vast space of chemically diverse odour
molecules. This task is accomplished by the combinatorial activation of approximately 400 …

Olfactory and taste receptors are expressed primarily in the nasal olfactory epithelium and
gustatory taste bud cells, where they transmit real-time sensory signals to the brain …

Abstract Purpose of Review Microbial short-chain fatty acids (SCFAs) are byproducts of
microbial metabolism which can be absorbed into the bloodstream of the host, where they …

Short-chain fatty acids (SCFAs) are important metabolites derived from the gut microbiota
through fermentation of dietary fiber. SCFAs participate a number of physiological and …

Nutrient sensing is a mechanism for organisms to sense their environment. In larger
animals, including humans, the intestinal tract is a major site of nutrient sensing for the body …

Olfactory receptors (ORs) are not exclusively expressed in the olfactory sensory neurons;
they are also observed outside of the olfactory system in all other human tissues tested to …

Essential oils have been used in multiple ways, ie, inhaling, topically applying on the skin,
and drinking. Thus, there are three major routes of intake or application involved: the …
