Hi
Here is a little insight as to why we are used to having little fat on our meat................
"It turns out that fat is good for more than introducing flavour and moistness, it’s also pretty good for making bombs. During World War II, handing over cooking fat to the government was doing your duty.
In America "The American Fat Salvage Committee" was created to urge housewives to save all the excess fat rendered from cooking and donate it to the army to produce explosives. fats are used to make glycerine, and glycerine is used to make things blow up.
Fats were also needed in higher quantities for industrial and military use. For example, the Navy used lard to grease their guns, so the butchers handed it over and as such it was rationed.
