The Ornish diet is a low-fat, vegetarian eating plan designed to prevent coronary artery disease progression and improve coronary artery plaques. It involves eating mostly plant-based foods and limiting animal products, refined carbs, high-fat foods, and processed ingredients. While olive oil is a recommended source of fat on the Ornish diet, some sources suggest that canola oil is a healthier alternative. Canola oil is rich in heart-healthy unsaturated fat and has been shown to have a positive impact on blood flow compared to olive oil. However, the whole food plant-based (WFPB) diet community is divided on the inclusion of added oils in the diet, with some recommending avoiding all added oils, including olive oil and canola oil.

What You'll Learn
Canola oil is recommended by Dr. Ornish
The Ornish diet is a very low-fat, vegetarian eating plan. It restricts dietary fat to less than 10% of daily calories, and requires that all fats come from plant sources. The diet is designed to be heart-healthy and to prevent coronary artery disease progression (CAD) and improve coronary artery plaques. It involves eating mostly low-fat, plant-based foods and limiting animal products, refined carbs, high-fat foods, and processed ingredients.
In addition, canola oil has been shown to have benefits for heart health. In a study by Robert Vogel in the Journal of the American College of Cardiology, olive oil was found to significantly reduce blood flow to different parts of the body, whereas canola oil and salmon did not. This measure of blood flow, called flow-mediated vasodilation (FMD), is a standard, well-accepted test by the American Heart Association and others. In this study, blood flow (FMD) was reduced by 31% after an olive-oil meal but was not reduced by a meal with a similar amount of fat from canola oil or salmon, probably due to the higher content of the protective omega-3 fatty acids in canola oil and salmon.
However, it is important to note that the whole food plant-based (WFPB) diet community is divided on the topic of added oils in the diet. While some recommend avoiding all added oils, including olive oil, others believe that a diet centred around whole plant foods, whether it contains added oils or not, is the healthiest choice. Ultimately, it is best to concentrate on the quality of the whole diet rather than individual components.

Canola oil is not genetically modified
Canola oil is a cooking oil derived from the canola plant, a "distant younger cousin" of the rapeseed plant. It was developed in Canada in the 1970s using traditional crossbreeding methods and without the use of biotechnology. The name "canola" is a portmanteau of "Canadian" and "oil".
Canola oil is often assumed to be genetically modified due to the prevalence of GMO canola crops. Indeed, the vast majority of canola grown in North America today is genetically modified, with estimates ranging from 95% to over 96%. This number, however, is slowly decreasing as non-GMO canola oil gains popularity among consumers and natural food manufacturers.
Non-GMO canola oil is produced using original seeds from the 1970s, which were bred through traditional methods to be low in erucic acid and glucosinolate. These seeds are now used for non-GMO and organic canola oil production. While GMO crops are made through biotechnology, non-GMO canola oil is produced using traditional crossbreeding techniques.
The Non-GMO Project, a non-profit organisation, works to preserve the non-GMO seed supply and support farmers who grow non-GMO crops. They offer a verification system, where a product can be traced back in the supply chain to ensure it was sourced from non-GMO crops. Their Butterfly label is a reliable way for consumers to identify non-GMO products, including canola oil.
In summary, while most canola crops grown in North America are genetically modified, it is important to distinguish that canola oil itself can be produced from non-GMO seeds. The Non-GMO Project provides resources for consumers to identify and support non-GMO products, ensuring that they have a choice in the type of products they purchase and consume.

Canola oil is not toxic
The concerns about the safety of canola oil stem from the use of solvents like hexane during the extraction process. Hexane is a volatile solvent with a low boiling point, and its use can affect the stability of the oil's molecules, potentially leading to rancidity and the destruction of omega-3 fatty acids. However, the levels of hexane residue in canola oil are estimated to be very low, and there is no evidence to suggest that these trace amounts pose any health risks.
Canola oil is a rich source of polyunsaturated fatty acids (PUFAs), including omega-3 and omega-6 fatty acids, which offer health benefits. It has been associated with improved heart health and a reduction in disease-related factors. A 2011 study found that individuals who consumed more canola oil experienced lipid-lowering effects, indicating potential benefits for cardiovascular health. Additionally, canola oil has a lower amount of saturated fat compared to other vegetable oils, further contributing to its reputation as a heart-healthy option.
While some studies have questioned the potential harm of canola oil, the consensus among experts is that it is a healthy choice. Dr. Dean Ornish, a renowned expert in the field, recommends canola oil over olive oil due to its health benefits. Canola oil has been found to significantly reduce blood flow to different parts of the body, which is a positive measure of cardiovascular health. It is also an inexpensive option for cooking or as a salad oil, making it accessible and beneficial for those seeking a healthy and affordable oil option.

Canola oil is rich in heart-healthy unsaturated fat
The Ornish diet is a low-fat, vegetarian eating plan. It is designed to be a heart-healthy eating plan and restricts dietary fat to less than 10% of daily calories, with all fats coming from plant sources. The diet includes fruits, vegetables, whole grains, legumes, and soy foods, with egg whites and non-fat dairy also permitted.
Canola oil is one of the approved plant-based sources of fat on the Ornish diet. It is rich in heart-healthy unsaturated fat, notably alpha-linolenic acid (an omega-3 fat, similar to that found in fish oil). Omega-3 fatty acids are known to reduce inflammation and are "heart-healthy". Canola oil is also high in omega-6 fatty acids, which have been linked to improved health outcomes.
In addition to its heart-health benefits, canola oil is also a good, inexpensive choice for cooking or as a salad oil. It is important to note, however, that like all oils, canola oil is high in calories, with 125 calories per tablespoon.
While the Ornish diet does allow for some healthy fats, it is important to remember that the diet is primarily plant-based and centered around whole foods. The Ornish diet recommends that healthy fats make up about 10% of your total daily calorie intake, with most of those fats coming from naturally occurring fats in whole foods like whole grains and legumes.
Some sources suggest that the Ornish diet may be too restrictive and may increase the risk of nutritional deficiencies without proper planning. It is always best to consult with a healthcare professional or registered dietitian to ensure that your dietary choices align with your individual needs and health goals.

Canola oil is a good, inexpensive choice for cooking
The Ornish diet is a low-fat, vegetarian eating plan that restricts dietary fat to less than 10% of daily calories, with all fats coming from plant sources. It is designed to be a heart-healthy eating plan that prevents coronary artery disease progression (CAD) and improves coronary artery plaques. The diet includes fruits, vegetables, legumes, whole grains, and limited amounts of high-fat foods like nuts, seeds, and vegetable oils.
Canola oil is a recommended oil by Dr. Dean Ornish. It is a good, inexpensive choice for cooking as it is rich in heart-healthy unsaturated fat, notably alpha-linolenic acid (an omega-3 fat, similar to that found in fish oil). It is also a good source of omega-6 fatty acids. Canola oil does not have any adverse effects on health, contrary to some misconceptions. It is not toxic and does not cause heart disease or multiple sclerosis. Instead, it is beneficial for heart health as it does not reduce blood flow in the body, unlike olive oil, which reduces it by 31%.
In addition, canola oil is not genetically modified but comes from a hybrid plant developed in Canada during the late 1960s to 1970s using traditional pedigree hybrid propagation techniques involving black mustard, leaf mustard, and turnip rapeseed. This process ensures that the oil is extremely low in toxic substances.
While canola oil is a healthy and inexpensive option, it is important to remember that it is still high in calories, with 125 calories per tablespoon, so it should be consumed in moderation as part of a balanced diet.
Overall, canola oil is a good choice for cooking on the Ornish diet as it aligns with the diet's focus on heart health, plant-based sources of fat, and limited animal products.
