Oh dear I seem to have started a bit of a row
!
I am a scientist by training, and come from a medical family- so I do know how to read a study and find information.
I also know that an awful lot of studies start from the certain view point that natural animal fats are dangerous, and whatever the actual findings of a study, saturated fat intake is usually pointed at as a cause IMO often without considering the role of other fats in the diet (processed seed oils, manufactured fats), or the role of carbohydrate in the diet, as carbohydrates are widely perceived to be "healthy" as they are low fat.
Actually in the study Cote linked, it was pointing the finger firmly at level of carbohydrate consumption in obese individuals as the biggest risk factor in gallbladder disease, but also said cholesterol consumption and plant fibre intake was protective.
So it's not really the best study to debunk my crazy ideas
.
We are all adults, we are free to look at the evidence and compare different views and theories - forget gallstones for a wee while, within medicine as a whole, not just the area of nutrition, there are a lot of "known" treatments and facts which are not evidence based, or done because "that's what we do".
I'd like to think that is changing now, Ds1, now 3rd year med student, is certainly being given a solid "evidenced based" training (rather, and encouragement to go away and find papers that contradict the current POV), although his university is very very research orientated.
Just to throw the car amongst the pigeons...
IMO (and the opinion of many others, including a small but growing number of reactionary doctors - it's not just me!)
Animal fats, as found naturally (ie on the animal, in the eggs, round the organs), are healthy fats. Especially if the animal has been raised on a natural diet (the diet the animal evolved eating)
Processed, chemically extracted fats (veg/seed oils) are bad.
Grains (all of them), are damaging and cause many health problems in both animals we feed them to, and to humans. They are full of natural plant toxins.
Grains are not part of the natural human diet - before the Neolithic (the advent of agriculture), grains were not consumed (not in sizeable quantities).
We should go back to eating real foods, non processed, fresh.
So- lots of leafy veg, fish, meat and eggs, some nuts and fruits, some starchy veg (less if you need to lose weight). Some cream, cheese and butter if you can tolerate dairy.
The rule is pretty much "if you can pick it or dig it up or kill it with your spear, eat it"
