Beans & Beef Tie in Satiety Showdown

Beans & Beef Tie in Satiety ShowdownSatiety is a big buzzword when it comes to selling foods these days.

Satiety – which refers to the feeling of fullness – is the opposite of hunger; and don’t we all want to feel un-hungry?

In nutrition science, it is generally well established that protein, fat and fiber all contribute to satiety. Although proving as much has been difficult.

A recent study just published in the Journal of Food Science found that beans may be as satiating as beef – but consumers don’t expect it to be.

In this study, researchers from the University of Minnesota served subjects 1 of 2 different types of loafs:

  • A meatloaf containing 26 g protein and 3 g fiber
  • A bean loaf containing 7 g protein and 12 g fiber

Turns out, whether subjects were served the bean or the meatloaf had no impact on the amount of food and snacks ate later in the day – indicating similar satiety levels.

Now, when researchers ASKED the subjects about feeling full, when they knew they were getting the bean loaf, they reported feeling less full vs. the meatloaf. This indicated that the subjects were not expecting to feel as full from eating beans vs. fiber.

The authors suggest that this discrepancy in actual vs. perceived satiety can be described as “food neophobia” – and like most things in the satiety stratosphere, probably needs to be studied more.

Although this particular study is small, it contributes to a growing pool of evidence supporting the move towards a more plant-based diet and away from animals. Plant-based protein appears good for the planet, and perhaps for your appetite as well.
