it goes rancid too quickly and easily. birds dont eat it. thats good enough for me. rancid fat is horrible. it interferes with fat soluble vitamin usage. it contaminates healthy fat cells. i dont want rancid fat in my brain. some say the exhaust and ozone in traffic is what makes brain cells rancid and contributes to road rage.
there are better substitutes. go with hemp seed oil for efas and you cant go wrong.
