What the research says
RBD-processed seed oil in the same group as palm, soy, sunflower; deodorised and bleached so it loses all natural identity, becomes 'interchangeable' with other RBD oils so manufacturers swap based on market price.
[ultra-processed-people] RBD-processed seed oil in the same group as palm, soy, sunflower; deodorised and bleached so it loses all natural identity, becomes 'interchangeable' with other RBD oils so manufacturers swap based on market price.
[metabolical] Most commercial canola is partially hydrogenated for shelf stability, generating trans fats. When heated, cis-double bonds isomerize to trans-double bonds; a study showed rats fed canola oil heated to high temperature for falafel frying had higher rates of colon tumors and gut inflammation than rats fed lower-heat canola.
