If by “belog” you mean “belong”/“is this true,” then yes—the Facebook story appears to be based on a real scientific story, but the headline exaggerates the conclusion.
The 117-year-old was María Branyas Morera, who died in 2024 at 117 years and 168 days. Researchers analyzed her genome and biological samples and found several unusual features associated with healthy aging, including favorable genetic variants, low inflammation, excellent cardiovascular markers, and a remarkably healthy gut microbiome.

What was the “one food”?
Yogurt. Branyas reportedly ate about three yogurts every day, and researchers found unusually high levels of beneficial Bifidobacterium in her gut. Her Mediterranean-style diet may have helped support this microbiome.

But there is an important catch: scientists did not prove that yogurt made her live to 117. The research involved essentially one exceptional individual, and her longevity likely resulted from a combination of genetics, diet, physical activity, social factors, and other environmental influences. The researchers themselves cautioned that the connection between her yogurt consumption and her microbiome could not be definitively established.

So the Facebook headline “doctors investigate DNA … to find one food that contributes to longevity” is a catchy simplification. A more accurate takeaway is:
Yogurt may support a healthy gut microbiome, but there is no single food proven to make people live to 117.
