True. And it's also a nonsense.

Don't know which ancesstors she's talking about, but 3 meals were basically a standard in ancient Greece and Rome.

In middle ages, dinner and supper was commo pattern within wealthy and clergy (for religous reasons mostly). Peasants have two meals too (breakfast and laege meal after work). Later even 3 meals.

Rockefellers have emeged in 17th century and I suppose they didn't give shit about what and how people eat back then.
