Canola Oil May Reduce Dangerous Abdominal Fat
Visceral fat (the fat around the abdomen) increases the risk of cardiovascular disease, metabolic syndrome, and diabetes. A recent study suggests that consuming canola oil may help reduce abdominal fat in as little as four weeks.
Participants in the study included 101 people with abdominal obesity or increased waist circumference and were at risk for or already had metabolic syndrome. They were instructed to consume either conventional canola oil, high-oleic acid canola oil , high-oleic acid canola oil with DHA omega-3 fatty-acids, or corn/safflower oil and flax/safflower oil for four weeks. Each intervention was followed by a two to four week washout period before they underwent the next intervention. All the participants underwent all four interventions.
The oil was consumed in the form of two smoothies that also included 100 grams of orange sherbet, 100 grams of non-fat milk, and 100 grams of frozen unsweetened strawberries. The quantity of oil was based on each individual’s calorie needs.
At the conclusion of the study, the researchers noted a 0.25 lb. reduction in belly fat after the canola oil and high-oleic acid canola oil interventions. They also noted a correlating reduction in blood pressure and triglyceride levels.
Researchers from Penn State conducted the study. It was published on November 2, 2016, in Obesity Symposium.
Canola oil is high in the monounsaturated fat oleic acid, which can be found in avocados, olive oil, and canola oil. Previous studies suggest that oleic acid may improve fasting plasma glucose, insulin sensitivity and blood circulation.
