Eräs rasvahypoteesin (tyydyttynyt rasva aiheuttaa sydäntauteja) kulmakiviä on Ancel Keysin tutkimus 1950-luvulta. Sitä ei pikaisella silmäyksellä mainittu vielä tässä ketjussa. Tutkimusta on kritisoitu siitä, että tutkimukseen otettiin mukaan vain maat, jotka tukivat johtopäätöstä.

But what of the supportive data? Surely it must be based on something? Of course it is, and what it is mainly based on is Ancel Keys and his seven countries study - possibly the single most important piece of research in the development of the saturated fat hypothesis. This study ‘proved’ that the more saturated fat consumed in a country, the greater the rate of CHD. Or did it?
If you chose, in the mid-nineteen fifties, to study the seven countries that Ancel Keys looked at.
Italy, Greece, Former Yugoslavia, Netherlands, Finland, U.S., Japan
Then you could find an almost perfect correlation between saturated fat intake and CHD.
However, if Ancel Keys had chosen to study:
Finland, Israel, Netherlands, Germany, Switzerland, France, Sweden
Then he would have discovered the exact opposite. Namely, the more cholesterol/saturated fat consumed, the less CHD. Indeed, if you were to have chosen any other seven countries in the world, apart from the ones Ancel Keys chose, you would get a different set of results. How Ancel Keys came to choose his seven countries will probably never be known – unless he makes a deathbed confession.

Ancel Keys kuoli vuonna 2004, 100 vuoden ikäisenä. Epäolennainen tieto: Toisessa maailmansodassa USA:n armeijan käytössä olleet ruoka-annokset olivat nimeltään
K-ration, jossa K tuli annoksen kehittäjän sukunimestä (Keys).
