Like broccoli? Thank your microbiome. #shorts #science

The video explains why broccoli and related plants have a strong smell due to sulfur compounds. These compounds are broken down by microorganisms in the mouth, releasing unpleasant odors. The intensity of the smell varies among individuals based on their unique microbiomes. As people age, their microbiomes change due to exposure to new microorganisms, which can alter their perception of broccoli's smell.

What are some sources through which new microorganisms can be introduced to a person's microbiome?

Why might caregivers who loved broccoli have different microbiomes compared to others?
