A new research shows that satiation depends on the thickness of food and not on the amount of calories or energy value.
A group of researchers from Wageningen University in the Netherlands experimented with four types of dairy-based shakes made from cream, sugar, water, vanilla, protein powder, and maltodextrin, a food additive made from starch. The shakes had the same nutritional makeup, but differed in viscosity and energy value. The viscosity was either thick or thin, while the energy value was either 100 or 500 calories.
The study involved fifteen men who were asked to drink the shakes. After consumption, the researchers took MRI scans of the participants’ stomachs to determine the volume of liquid inside.
The results show that the feeling of fullness for the participants was directly related to the drink’s viscosity and not its energy value. Participants who drank the thick 100-calorie shakes reported feeling fuller than those who drank the thin 500-calorie shakes.
The researchers called this phenomenon “phantom fullness.” It refers to the feeling of being more satiated not because of the food’s calorie count, but because of its thickness.
Aside from satiation, thick drinks like smoothies, or fruits blended with milk, juice, or yogurt have multiple health benefits and provide essential vitamins and oils. Joseph Price, associate professor at Brigham Young University, believes that it is the most convenient way to add fruits to one’s diet, especially for people with fast-paced lifestyles.
However, other experts contend that long-term intake of smoothies increases the risk of diabetes and other health problems such as obesity. Barry Popkin, a professor from the University of North Carolina at Chapel Hill, believes that rather than drinking smoothies, people should just drink vegetable juice or eat fruits.
