Use butter, lard - or chicken fat. That's what my grandmother
used. She never had any of the other oils in her house. She never exercised,
made here own bread, doughnuts, noodles, cakes and everything else with real ingredients
including lard in particular. She lived until age 83 and all of her five
children lived well into their 80's and they generally ate like she did.
In fact one of her daughters, my aunt who I lived with for awhile, lived to be
100 eating toast, bacon and coffee for breakfast and doughnuts and other sweets
for snacks. This woman was overweight and died only because she longed for
her husband who preceded her in demise just a few months before, only making it
to 99 (eating the same way she did) - two months short of his hundredth
birthday.
