It shouldn't be surprising that lard is healthier than vegetable oil. Think about things like cotton-seed oil, rapeseed oil and canola oil. These things are imposible to consume without industrial processing. Meat has always been a staple in the human diet. It's the hunt in hunting and gathering: the gathering mainly beeing fruit, but admittedly also seeds. but of course the oil obtained in seeds never reached the amount we have now. While that's not conlclusive in itself there has actualy been a lot of research on polyunsaturated fatty acids lately with worrying results.
One could reasonably phrase the question this way: what evidence is there that polyunsaturated fatty acids are healthy?
Also, it's unreasonable to say that in a study of 15,000 people, the cause of those who used vegetable oil were those with ASCVD and therefore chose to cook with it.
In any event, this possibilty is ruled out:
>Based on 15,242 Chinese elderly people over 65 years old who had long-term adherence to dietary habits and types of edible oils,[...]
>And of course the usual link to wider socioeconomic status needs a bit more exploring.
This is accounted for in the article. In fact "evaluation of other variables" makes up the entire alaysis.
