Vegetable oil, including olive oil, is energy dense and nutrient poor. Foods with these qualities are defined as junk foods and when consumed in significant amounts cause weight gain and/or nutrient displacement.

Vegetable oil is almost pure fat and has the highest energy density of any food, more than twice that of sugar. One Australian tablespoon (20ml) of oil provides 160 calories (670kj), the same number of calories as a can of Coke. Adding oil to a meal adds a lot of calories without any appreciable change in portion size. Most people continue to eat the same portion sizes, but the calorie content of the meal is higher, leading to systemic weight gain over time. Recent olive oil research in Australia had subjects consume 60ml of olive oil per day – that’s 480 calories (2000kj) which is about 20-25% of an average person’s daily energy needs. The study observed that energy intake increased by 428 cal (1800kj) per day when subjects added 60ml of olive oil to their diet. However, in the long term, subjects may partially compensate by eating less of other foods, which leads us to the other half of the junk food problem.

Vegetable oils contain very few nutrients. Most have some vitamin E but virtually zero protein, iron, calcium, dietary fibre, and very little omega 3 fats. The extraction of oil from olives, seeds, etc is a form of food processing that removes most of the nutrients: this includes cold pressed oils. Vegetable oils ‘displace’ nutrients from the diet. When we eat more calories from one source, we tend to eat less calories from other sources: eat more low nutrient ‘junk’ and you are likely to eat less nutrient rich whole foods. If 20ml of olive oil were to displace equal calories of wholemeal wheat pasta the nutrient ‘displacement’ would include 4.9g fibre, 2mg iron, 31mg calcium, 0.7mg zinc and 42mg magnesium.

Consuming vegetable oil adds a lot of calories but very few nutrients. If you reduce food intake to compensate for the extra calories you will have less nutrients. If you maintain food intake to conserve nutrients you will gain weight. It’s either weight gain, nutrient loss or a combination of both.

This 144g serve of cooked brown rice has the same number of calories as 20ml of oil (160 calories).
