Recent research shows canola oil and high oleic canola oil, both rich in monounsaturated fats, may help reduce abdominal fat.
Researchers examined 101 adults with abdominal obesity. Participants followed isocaloric diets (50% carbohydrate, 15% protein, 35% fat) and consumed a daily smoothie containing one of five types of oil: canola, high oleic canola, high oleic canola with DHA, a corn and safflower oil blend, and a flax and safflower oil blend. Subjects were randomly assigned to a sequence of the five oils. Each diet was followed for four weeks, with a two- to four-week rest period between each diet, during which participants followed their usual diets. Results showed a significant decrease in abdominal fat when subjects consumed smoothies prepared with canola and high oleic canola oil, both of which are high in monounsaturated fats. Additional benefits include decreased blood pressure and triglycerides.
