The Mediterranean and Nordic Diet: A Review of Differences and Similarities of Two Sustainable, Health-Promoting Dietary Patterns
2021 Jun 25 Frontiers in Nutrition Krznarić , Karas I, Ljubas Kelečić D, Vranešić Bender D
The main difference between the two diets lies in their primary fat sources, with olive oil being synonymous with the MD and rapeseed/canola oil being more prevalent in the ND. Longitudinal epidemiological studies support the MD as a preventive measure against chronic diseases, while the ND requires further research due to discrepant results. Nevertheless, studies suggest that both diets may be associated with lower risks of chronic diseases, disability, and mortality. Future longitudinal and large prospective studies are needed to provide more evidence-based recommendations.

Chronic consumption of thermally processed palm oil or canola oil modified gut microflora of rats
2021 Jan Food Science and Human Wellness Ruan M, Bu Y, Wu F, Zhang S, Chen R, Li N, et al.
Heated canola oil consumption elevated plasma total cholesterol and LDL-c levels compared with unheated canola oil, while heated palm oil did not have these effects. Additionally, consumption of heated palm oil significantly increased the relative abundance of Lactobacillus and Roseburia in the gut compared with non-heated palm oil or both canola oil groups. The heating process may enhance the effects of palm oil on the proliferation of probiotics like Lactobacillus and weaken the effects of canola oil on cholesterol transport and metabolism.

Canola oil (CO) significantly reduced total cholesterol, low-density lipoprotein cholesterol (LDL-C), LDL-C to high-density lipoprotein cholesterol ratio (LDL/HDL), total cholesterol to HDL ratio (TC/HDL), apolipoprotein B (Apo B), and Apo B/Apo A-1 compared to other edible oils, including olive oil, sunflower oil, and saturated fats. Replacing CO with ~15% of total caloric intake provided the greatest benefits based on the nonlinear dose–response curve.

The effects of extra virgin olive oil and canola oil on inflammatory markers and gastrointestinal symptoms in patients with ulcerative colitis
2020 Jan 03 European Journal of Clinical Nutrition Morvaridi M, Jafarirad S, Seyedian SS, Alavinejad P, Cheraghian B
Extra virgin olive oil (EVOO) consumption led to a significant decrease in inflammatory markers (erythrocyte sedimentation rate and high-sensitivity C-reactive protein) and improved gastrointestinal symptoms, including reduced bloating, constipation, fecal urgency, incomplete defecation, and overall gastrointestinal symptom severity in ulcerative colitis (UC) patients.

Systematic Review Almond Avocado Flaxseed
The research was carried out by conducting a systematic evaluation of existing guidelines, systematic reviews, and Randomised Control Trials (RCTs); we have only referred to the latter for studies on coffee intake. This was done on databases such as PubMed, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials, alongside a search on the Trip database for guidelines. The time frame for the study was from its inception up until June 2019 and October 2019 respectively. Studies were included if they were at least 13 days in duration and were in English. Using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method, 37 guidelines, 108 systematic reviews, and 20 RCTs were evaluated to analyze the strength of evidence in the context of food impacts on LDL cholesterol levels.
The results of the research reveal that foods high in unsaturated and low in saturated and trans fatty acids such as rapeseed or canola oil, those with added plant sterols/stanols, and those high in soluble fibre like oats, barley and psyllium cause moderate reductions in LDL cholesterol. A moderate to a large increase was observed with unfiltered coffee though. Soy protein, tomatoes, flaxseeds, and almonds cause small reductions. Meanwhile, foods like avocados and turmeric cause moderate to large reductions with a moderate level of evidence supporting this observation. Other foods like pulses, hazelnuts, walnuts, high-fiber/wholegrain foods, green tea result in small to moderate reductions, and sugar causes a small increase. Several foods identified were either neutral or had low or very low evidence regarding their effects on LDL cholesterol levels.

Effects of Canola Oil Consumption on Lipid Profile: A Systematic Review and Meta-Analysis of Randomized Controlled Clinical Trials
2018 Oct 31 Journal of the American College of Nutrition Ghobadi S, Hassanzadeh-Rostami Z, Mohammadian F, Zare M, Faghih S
Canola oil (CO) consumption significantly reduced TC and LDL, with no significant effects on HDL, TG, Apo B, and Apo A1. Subgroup analyses indicated that the effects on TC and LDL were more pronounced in participants over 50 years of age and with an intervention duration of over 30 days. Additionally, CO showed a greater reduction in LDL and TC compared to sunflower oil and saturated fat. The meta-analysis suggests that CO consumption improves serum TC and LDL, potentially delaying the progression of heart disease.
