After analyzing the results, they found that the whey and proteins naturally present in regular milk releases gastric hormones that slow digestion and increase feelings of fullness, which could reduce the risk of obesity.
They noted there was only a small difference in how much people ate later in the day, but they discovered high-protein milk reduced blood glucose a tad bit more than regular milk even after lunch.
“Milk with an increased proportion of whey protein had a modest effect on pre-lunch blood glucose, achieving a greater decrease than that provided by regular milk,” they said.
“This study confirms the importance of milk at breakfast time to aid in the slower digestion of carbohydrate and to help maintain lower blood sugar levels,” Goff added. “Nutritionists have always stressed the importance of a healthy breakfast, and this study should encourage consumers to include milk.”
Previous studies have shown the benefits of consuming dairies high in protein.
In 2016, researchers at Israel's Tel Aviv University concluded that a large whey protein breakfast may help people manage Type 2 diabetes.
"Whey protein powder," the authors wrote, "which is a byproduct of milk during cheese production, induced greater satiety and reduction of glucose spikes after meals compared to other protein sources, such as eggs, soy or tuna."
