Inulin, Whey, and Dextrin-Enriched Coffee May Lower Feelings of Hunger, Boost Satiety
A recent study suggests that drinking two cups of coffee enriched with inulin, whey protein, and dextrin per day may lower feelings of hunger and boost satiety.
Participants in the study included 269 people who were given either a control beverage of coffee alone; coffee with whey protein, inulin, and dextrin; or coffee with whey protein and inulin. They were instructed to drink their beverage twice daily for one week.
No significant differences in hunger or satiety were found between the 3 groups after one week. However, after 2 weeks, the inulin, whey, and dextrin coffee group had significantly lower hunger than the other two groups. That group also had a significant increase in satiety scores when compared to the control coffee group. Additionally, the inulin, whey, and dextrin group felt fuller compared to the control group and ate less than the other two groups.
The only adverse effects reported were higher abdominal pain after the first cup of inulin and whey coffee versus the inulin, whey protein, and dextrin coffee. The participants also noted more abdominal pain after the second cup of inulin, whey protein, and dextrin coffee and the control coffee.
Researchers from Tel Aviv University conducted the study. It was published on December 27, 2015, in the journal Nutrition.
Inulin is soluble dietary fiber that is non-digestible. It passes through to the large intestine and becomes healthy intestinal micro flora. Dandelion root, chicory root and elecampane root all have high concentrations of inulin. Previous studies have shown that inulin strengthens the immune system, enhances the absorption of minerals such as calcium and magnesium, improves digestion and lowers cholesterol.
Whey protein is one of the two proteins found in milk, but is only approximately 1% of the composition of milk. It is obtained as a byproduct of cheese making and can be purchased in powder form from health food stores. Additionally, it can be found in yogurt and in ricotta cheese, which is one of the only cheeses that do not have the whey removed.
Dextrin is a natural fiber that supports the body’s ability to remove wastes. It has the ability to lower the glycemic load of a high-carbohydrate meal, and previous stud
