Wow! This is educative. Av always known fats and oil to be classes of food for the nourishment of human body and never knew that it could as well be used for the above mentioned things when industrialized.
fat origin is from animal such as pork,beef tallow and butterfat,while oil is getting from plant and fish.
Thanks for mentioning these sources of fats and oil. Sally you need to see the way i eat pork, yet i don't get fat. Lol.
Well articulated @sallyquin, internet network has really dealt with me.
it not necessary for you to be fat if you eat pork meat......
Unless you're trolling, I'm at a loss with how you can think this was well articulated
