Meat and fat
Rabbits have an extremely lean meat, so lean that frontier people colonizing the US, would get a disease from living off rabbit meat because they lacked adequate fat in their diet.
CornStock are livestock that are fed exclusively corn or corn stalks. Corn is highly imbalanced in terms of essential fatty acids. It has far too much omega-6 which increases the need for omega-3's which typical human diets are deficient in. Livestock who are fed mostly corn, acquire the same problem.
Second problem with cornStock is they are way fattier than animals with a more optimal diet and animal fat tends to be high in saturated fat and associated with heart disease, stroke, and cancer.
It is not like a big deal or anything, just 2 out of 3 people will die of heart disease or stroke and the primary causes seems to be atherosclerosis caused by eating cornStock (and lack of exercise). Cancer is the second leading cause of death and saturated (animal) fat and red meat are also associated with some cancers. These are just useless old people in their 50s 60s and 70s, far past the age of beauty. Who would even want to live so long? This is no reason to give up that duliceeous cornBeef patty deep fried in grease. Muscovy steak sammich?!?!? Rabbit taco salad?!?!? OMG gross! You didn't kill that cuddly snuggly harmless bunny did you?!?!? How uncivilized. Why can't you buy the meat or leather from some animal who was tortured, you know, somewhere where you can't see it?
Beef are typically "force-fed" corn and corn stalks in a feed lot, which is not a natural diet and it would kill them if they were not slaughtered first. It is Truth (according to some guy getting into his truck in the documentary King Corn).
CornBeef are far higher in fat than grass-fed beef and this sends the calories from fat through the roof.
Essential fatty acid
Essential fatty acids are polyunsaturated fats. They include omega-3s and omega-6s. It is recommended to eat no more that four times as much omega-6 than omega-3, or the omega-6 reduces the function of the omega-3s.
Sources of omega-3s include fats of oily fish including salmon, sardines, orange roughy, mackerel, and anchovies. If taking fish oil capsules it is advisable to eat a capsule with every meal particularly if one has extra body fat, high cholesterol, or doesn't get much exercise. Non-"oily" fish store the omega-3s in their livers. Cod liver oil is another source, although more than one capsule per day is not advisable to avoid vitamin A overdose. Canola oil is inexpensive and has the most omega-3s of any common oil besides the expensive flax seed oil. Vegenase is a vegan mayonnaise made exclusively from Canola oil and it tastes only a little less rich than other commercial mayo. Flax seed is very high in omega-3s. Ground flax seed (flour) can be added to all sorts of things without making them taste bad.
Olive oil is more expensive than Canola oil but it is higher in monounsaturated fat. There are some oils on the market that can have a higher percentage of monounsaturated fat than olive oil such as high-oleic safflower oil. Oleic acid is a monounsaturated fat.
