Canola oil or rapeseed oil is pure fat and doesn't contain any carbs.
Note that fat affects gut motility and causes flareups in some individuals.
Canola oil is a vegetable oil derived from a variety of rapeseed that is low in erucic acid, as opposed to colza oil. There are both edible and industrial forms produced from the seed of any of several cultivars of the plant family Brassicaceae.
Canola oil is considered safe for human consumption and has a relatively low amount of saturated fat, a substantial amount of monounsaturated fat, with roughly a 2:1 mono- to poly-unsaturated fats ratio.
In 2006, canola oil was given a qualified health claim by the United States Food and Drug Administration for lowering the risk of coronary heart disease, resulting from its significant content of unsaturated fats.
