Since I eat quite a lot of lard I was a bit worried about it's high PUFA content of approx. 12%.
But then I vaguely remembered an article which said that lard and human adipose tissue have a similar composition. After a little bit of research I found this pdf:
According to this study, the average human adipose tissue comprises of:
- MUFA: ~65%
- PUFA: ~12%
- SFA: ~23%
This is indeed nearly the same PUFA content as in lard. Although various sources state that overall PUFA consumption should be limited to less than 4% of the complete caloric intake.
Now the question is:
I assume the human body stores it's fat exactly in the most healthy composition. Anything else wouldn't make any sense from an evolutionary stance. Therefore, anybody burning body fat would automatically have a PUFA consumption of ~12%.
Can I conclude that a PUFA intake from lard is optimal for humans? And that the 4%-PUFA-calories-a-day rule doesn't sustain?
I should have mentioned that the study is about the adipose tissue composition of dialysis patients on the island of Crete - anyway the control group has nearly the same values.
Thanks for the answers so far! So it seems that like grainfed animals' fat composition changes along with their diet, the ratios in human adipose tissue change as well with diet.
Has anybody a comparable study about human adipose tissue composition maybe in other cultures?
