Oil Omega
Which oil is healthiest? Is canola oil bad? Is olive oil good? What other options are good?
Factors:
- Smoke Point
- Higher smoke point means less risk of introducing toxins and carcinogens during cooking. Or, from a different angle, allows a wider range of cooking temperatures without introducing toxins or carcinogens.
- Omega Ratio (3, 6, 9)
- Omega 3 is good, Omega 6 is bad, Omega 9 is good.
- GMO
- Genetic modification of crops poses various risks, from altering agriculture processes to nutrient and toxin content in the final product.
Notes
Olive Oil
"The reason extra virgin olive oil is deemed superior [to canola oil] is because of the way it is processed, its high concentration of polyphenols, and how its antioxidants withstand heat during cooking. Regular consumption of olive oil is associated with a reduced risk of early death, cardiovascular disease, cognitive decline, certain types of cancer, and diabetes." - https://www.verywellhealth.com/canola-oil-8407170
VOO Study

Section 2.3 shows a suspicious scoring system, in which a threshold is used to set a score to maximum positive or maximum negative. It does not identify the score values for oleic acid, which has a threshold very close to the values for canola (just below) and VOO (just above). Figure 1, the only figure showing the calculation of scores, does not show the calculation for canola oil.
