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

Canola v. VOO Study

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10180740/

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.

Canola TFA should be 0.4: https://en.wikipedia.org/wiki/Canola_oil#Nutrition_and_health

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

Canola Oil

"Compared with oils analysed in 2008( Reference Baylin, Mora-Plazas and Cobos-de Rangel 9 ), the 2013 data showed consistent reductions in SFA and TFA, and increases in n-3 fatty acids, for all oils (Table 2). In particular, reductions in TFA were significant for 18:1 and 18:2 in mixed oils and for 18:2 in sunflower oil. In terms of percentage reduction from 2008 to 2013 in 18:1 and 18:2 TFA, canola oil had 89 % and 65 % reduction, mixed oils had 44 % and 48 % reduction, and sunflower had 25 % and 51 % reduction, respectively." - https://www.cambridge.org/core/journals/public-health-nutrition/article/transfatty-acids-in-cooking-oils-in-bogota-colombia-changes-in-the-food-supply-from-2008-to-2013/149F8B8E6F17BF307D44A2AEC773C553

"Studies done on laboratory animals in the early 1970s[6] show that erucic acid appears to have toxic effects on the heart at high enough doses. However, more recent research has cast doubt on the relevance of rat studies to the human health of erucic acid. Rats are unusual in their inability to process erucic acid, and the symptoms in rats caused by a diet with high levels of erucic acid have not been observed in pigs, primates, or any other animals." - https://en.wikipedia.org/wiki/Erucic_acid

"Food-grade rapeseed oil (also known as canola oil, rapeseed 00 oil, low erucic acid rapeseed oil, LEAR oil, and rapeseed canola-equivalent oil) is regulated to a maximum of 2% erucic acid by weight in the US[10] and 2% in the EU[12] (was 5%[11] before 2019-11-19), with special regulations for infant food. Canola was bred from rapeseed cultivars of B. napus and B. rapa by Dr. Baldur Stefansson at the University of Manitoba, Canada in addition to being cultivated by ancient Chinese, Indian, and Japanese cultures. Canola oil is derived from a variety of rapeseed that is low in erucic acid, as opposed to colza oil." - https://en.wikipedia.org/wiki/Erucic_acid
