VOO scores 100, Canola scores 68, but the study is flawed. | |||
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 Oil == | |||
=== Smoke Point === | |||
"At 460℉ (238℃), canola oil has a higher smoke point than either regular or extra virgin olive oil — 410℉ (210℃) and 383℉ (195℃), respectively (11, 12)." - https://www.healthline.com/nutrition/canola-vs-olive-oil | |||
=== Trans Fat === | |||
"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 | |||
=== Erucic Acid === | |||
"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 | |||

<blockquote> | |||
Nutritionally, olive oil — especially extra virgin — is healthier than canola. | |||
People who regularly use olive oil have reduced heart disease risk factors, improved blood sugar levels, and a lower risk of death (17, 18, 19). | |||
For example, an analysis of 33 studies revealed that people with the highest olive oil intake had a 16% lower risk of type 2 diabetes than those with the lowest intake (18). | |||
Additionally, greater olive oil consumption is linked to a lower risk of stroke and a reduction in heart disease risk factors, including LDL (bad) cholesterol and triglyceride levels (17). | |||
Olive oil’s benefits can be attributed to its antioxidants and other plant compounds, which are especially abundant in extra virgin varieties (9). | |||
On the other hand, canola oil is highly refined, which drastically reduces its content of nutrients like essential fatty acids and antioxidants (1, 2). | |||
While canola is often promoted as a heart-healthy fat, current research is conflicting. Though some studies suggest that it’s beneficial, others indicate the opposite (1, 20). | |||
One study in 2,071 overweight or obese adults noted that those who often used canola oil had a higher risk of developing metabolic syndrome than those who rarely or never used it (20). | |||
Metabolic syndrome is a cluster of conditions characterized by excess belly fat and high triglyceride, cholesterol, blood pressure, and fasting blood sugar levels, which collectively raise your risk of heart disease (21). | |||
Keep in mind that many studies linking canola oil to heart-health benefits have been funded by the canola industry, potentially raising conflicts of interest. Overall, more research is needed on canola and heart health (1, 22, 23, 24, 25). | |||
In addition, rodent studies associate this oil with increased inflammation, a negative impact on memory, and lower blood levels of antioxidants (26, 27). | |||
Meanwhile, multiple studies show that extra virgin olive oil has anti-inflammatory properties and heart-health benefits (28, 29, 30). | |||
As far as your health is concerned, more evidence supports the benefits of olive oil over canola. | |||

Monounsaturated fat of mixed animal and vegetable sources per se did not yield any significant effects on these outcome parameters. Subgroup analysis indicated that only olive oil (the primary monounsaturated fat source in south European countries) is was associated with a significant risk reduction for several outcomes. These data provide evidence that the source and origin of MUFA within a specific diet should be taken into account in order to evaluate the potential benefits of this type of fatty acids. Further studies are required evaluating specific food sources of MUFA and risk of all-cause mortality and CVD events." | |||

TL;DR:
- EVOO health benefit is sufficiently probable to make it worth using.
- Regular olive oil is harder to get excited about (lacking the antioxidants in EVOO).
- The canola oil industry group published a sketchy "study".
- Some of the "problems" with canola oil are flawed; either from older data or from industrial rapeseed oil.
The Question
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)
- GMO
- Genetic modification of crops poses various risks, from altering agriculture processes to nutrient and toxin content in the final product.
- Erucic Acid
- May be linked to heart disease.
- Trans Fats
- Early canola oil had higher trans fat content.
- Antioxidants
- EVOO has loads of antioxidants.

- "the effects of olive oil and/or its phenolic compounds specifically on individuals with established CAD are still scarce. In this sense, more clinical trials, preferably long-term studies, are necessary to evaluate and confirm the beneficial effects of the phenolic compounds present in the olive oil on the inflammatory process, both in the prevention and treatment of CAD."

- "In this cross-sectional study of young Australian adults, a higher cMetSyn score (greater probability of cardiovascular disease) was associated with more frequent consumption of low-fat oily dressings among participants who were healthy weight and frequent use of [either sunflower or] canola oil for cooking among those who were overweight or obese. Trimming fat from meat, cooking with olive oil and consumption of low-fat dairy products was not associated with metabolic risk."
- Note: The study did not distinguish between sunflower and canola oil. Canola oil is more popular than sunflower oil in Australia.

- "The present systematic review and meta-analysis provides evidence of favorable effects of olive oil on T2D (Type 2 Diabetes) risk and parameters of glycemic control. In light of other benefits, especially reported for extra virgin olive oil as an integral part of a Mediterranean diet, this vegetable oil represents a suitable component of a balanced diet."

- "The results of the present meta-analysis indicate an overall risk reduction of all-cause mortality (11%), cardiovascular mortality (12%), cardiovascular events (9%), and stroke (17%) when comparing the top vs. bottom thirds of a combination of MUFA, olive oil, oleic acid, and MUFA:SFA ratio. Monounsaturated fat of mixed animal and vegetable sources per se did not yield any significant effects on these outcome parameters. Subgroup analysis indicated that only olive oil (the primary monounsaturated fat source in south European countries) is was associated with a significant risk reduction for several outcomes. These data provide evidence that the source and origin of MUFA within a specific diet should be taken into account in order to evaluate the potential benefits of this type of fatty acids. Further studies are required evaluating specific food sources of MUFA and risk of all-cause mortality and CVD events."
