Adherence
No single vegetable oil crop is inherently 'good' or 'bad'; the environmental and social impact depends entirely on the production system, trade practices, and local context.
Don't just look for 'palm oil-free' labels. Focus on supporting sustainable certification and production practices. No oil crop is inherently evil; the impact depends on how and where it is grown. Consider the broader environmental trade-offs of different oils.
ModerateQualifiesMEDIUM confidence
For every vegetable oil crop we reviewed we found examples of negative environmental and social impacts, and it seems that these impacts are associated with production and trade systems and practices rather than with the crops as such... Thus, despite strong societal views on the impacts of different oil crops, there are no inherently good or bad oil crops, but only good and bad ways of producing them.
Why this rating
The paper is a perspective/review synthesizing various studies on sustainability, acknowledging complexity and lack of simple answers.

- Trans-fatty acids produced through partial hydrogenation increase the risk of ischemic heart disease, whereas saturated and monounsaturated oils are more stable and safer for high-temperature cooking.Good
- Restricting saturated fat intake does not consistently reduce cardiovascular disease risk and may be associated with lower mortality when replaced by carbohydrates, challenging blanket low-fat dietary guidelines.Moderate
