Influence of Rapeseed Proteins on the Postprandial Metabolic Response

The current study is a monocentric, controlled intervention study that will be conducted as cross‐over design. Three interventions are planned and participants will be invited to consume a test meal with added rapeseed protein isolate, a test meal with added soy protein isolate and a test meal without additional protein. The evening before, the subjects will receive a standardized dinner. After a 12‐hour fasting overnight, a cannula will be placed. Blood samples will be taken before and after eating the test meal rich in carbohydrate and fat. The test meal consists of pasta with oily tomato sauce with either 25 g of rapeseed protein, 25 g of soy protein or no additional protein. A total of 11 blood samples will be collected over a period of 6 hours. In the meantime, the blood pressure and pulse will be measured repeatedly and information on satiety will be recorded. The interventions will be interrupted by a period of, at least, 2 weeks.
