When it comes to seed oils, and listening to both sides of the discussion on this matter, we've concluded that some observational and mechanistic evidence does exist supporting the notion that seed oils could be potentially harmful. However, this evidence doesn't translate well into evidence in humans where randomized controlled trials consistently support that there is nothing inherently and substantially harmful about seed oils and vegetable fats. Under a positive energy intake, seed and vegetable oils may offer protective capabilities against certain chronic conditions. Overall, until we find strong evidence in humans, we aren't too concerned about any sparse mechanistic or observational studies that may be of concern and may be nullified by mechanistic and observational studies supportive of seed and vegetable oils.
Under the caloric restriction, we aren't too concerned about the type of fat whether it's a saturated or polyunsaturated fat that may be alleged to be of concern.
Seed and vegetable oils provide energy and sustenance to many impoverished households and countries across the planet. Taking a drastic step such as removing or replacing seed oils without having compelling evidence from human beings would be a step back to helping the world and its denizens. If strong evidence in human-controlled trials is brought up, we would reconsider our position. Till then, we would urge caution against many diet camps and gurus who may be using very weak and cherry-picked evidence to take sustenance off your plate.
