Thank you for a wonderful presentation - are questions welcome? Presuming yes, Q: 1). WHICH fat was used in your SFD mice chow, please? (never mentioned) 2) Why was olive oil not represented, was it not used in diets? 3) Is a higher fat diet in a normal/low normal (65yrs) human predisposing to ?? which negative health outcomes as pertains to your mouse model studies? I am obviously a lay-person, and do not understand how to read your graphs sufficiently to address the human impacts. Thank you for the generous sharing of attributions within your presentation - your very kind demeanor also much appreciated. Brilliance And humanism, lovely combo.

Hi, thank you for the comments! And yes questions are welcome. Originally for SFD we used regular chow which mainly contains soybean oil. For later experiments we used control diets made from the same fat as the HFD (eg SFD 10% olive oil vs 40% olive oil for HFD). And olive oil was not included in the slides as we didn’t originally include an olive oil group, but we since have, and olive behaves the same as palm oil.

Specifically, what type of butter/quality was used? I would love to see a butter vs butter face off. 100% Grass fed, organic butter vs. the cheapest butter available in the supermarket. Bet you'd get different tumor growth results.

Additional question: If your premise is that animal fat contributes to cancer, why did you use butter that contains lactose and casein? You should definitely have used Ghee or a proper extract of butter because the additional components in butter are a fair criticism against your claim.
