I would love to know what the high fat diet consisted of in this study.

My guess is it was high veggie fat and not animal fat.  Most vivarium mice eat a hight grain based diet.  They add other stuff but it is grain based, usually.  Kinda kills the deal for me but I think I will add tangerine's to my list of fruits.  It can't hurt.

The article mentions Nobiletin. Further research on that indicates it is created from an extract of tangerine peels and other citrus fruit.  It is being studied as a "Self-microemulsifying drug delivery system"

I eat tangerines or Mandarin oranges as they are smaller than most other oranges making them lower in carbs and sugar.
