Canola Oil
Canola oil is a neutral-tasting vegetable oil pressed or extracted from low-erucic rapeseed varieties, then usually refined, bleached, and deodorized for food use. Restaurants use it for frying, cooking, baking, sauces, dressings, and packaged ingredients because it is mild, liquid at room temperature, relatively low in saturated fat, and widely available.

What this is
Canola oil is the food-market name for low-erucic acid rapeseed oil. FDA regulation defines food-grade canola as refined, bleached, and deodorized oil from specified Brassica varieties with erucic acid no more than 2% of component fatty acids. The credible food-safety review is narrow: low-erucic specifications, refined-oil process contaminants such as 3-MCPD and glycidyl esters, and oxidation products when frying oil is overheated or repeatedly reused. Current human evidence does not support treating ordinary canola oil at food-use levels as a broad inflammatory toxin, though restaurant exposure still depends on fryer practices and the overall food pattern.
Safety Review
The health areas reviewed when evaluating an ingredient. This does not mean the ingredient is proven to cause harm.
Canola oil is not strongly supported as a human inflammatory toxin at ordinary food-use levels. The more credible review focus is whether the oil meets low-erucic acid specifications, how refined-oil process contaminants such as 3-MCPD and glycidyl esters are controlled, and whether fryer oil is overheated or reused long enough to produce oxidation products. Cardiovascular biomarker studies generally evaluate canola as a replacement fat; they should not be read as proof that every restaurant frying use is beneficial, but they also do not support broad toxicity claims.
