Can’t answer the lard question except for the my own valley, but the best
fat to cook with by far is coconut oil; it produces almost no free
radicals, it is thyroid enhancing, and people use it to lose pounds,
increase their temperature etc…

There is an oils analysis spreadsheet there plus a snapshot if you don’t
have a spreadsheet program. It tells you exactly what fatty acids are in
each oil, and how oxidizable they are overall; which is, how much of a
free radical load each one imposes on your body. And diabetes can be both
caused and aggravated by free radical load.

You’ll have to be an oxyplus member to get them, but oxyplus is perhaps
the most useful general health discussion group on the planet anyway.
