Crisco aka vegetable shortening isn't that much healthier than butter.
Both has its pros and cons.
Vegetable shortening is hydrogenated vegetable fat that contains quite an amount of saturated fat. Although does not have cholesterol, but saturated fat can be harmful for health too.
Butter has an amount of cholesterol, but it has the benefits of vitamin A.
Of course, canola oil, olive oil or other oils like sunflower/corn oil would be good as it's rich in polyunsaturated and monounsaturated fat, tht's good for ur heart. But....would result in not a very nice cookie :P....
So, it's really a matter of moderation and personal diet choice.

An occasional treat mebbe??
