>Perhaps the most popular is the gut microbiome, which impacts human digestive health (this is the science behind your daily probiotic yogurt).

I don't believe there is any science behind the notion that yogurt is healthy for your gut as a probioitic. The bacteria in yogurt is lactobacillus, which is present in gut flora but a minor resident at best.

https://en.m.wikipedia.org/wiki/Gut_flora >About 99% of the large intestine and feces flora are made up of obligate anaerobes such as Bacteroides and Bifidobacterium.

These are not present in yogurt and no amount of yogurt eating will help introduce them to your gut.
