WEST LAFAYETTE, Ind. - Spicing up your daily diet with some red pepper can curb appetite, especially for those who don't normally eat the popular spice, according to research from Purdue University.
"We found that consuming red pepper can help manage appetite and burn more calories after a meal, especially for individuals who do not consume the spice regularly," said Richard Mattes, distinguished professor of foods and nutrition who collaborated with doctoral student Mary-Jon Ludy. "This finding should be considered a piece of the puzzle because the idea that one small change will reverse the obesity epidemic is simply not true. However, if a number of small changes are added together, they may be meaningful in terms of weight management. Dietary changes that don't require great effort to implement, like sprinkling red pepper on your meal, may be sustainable and beneficial in the long run, especially when paired with exercise and healthy eating."
Other studies have found that capsaicin, the component that gives chili peppers their heat, can reduce hunger and increase energy expenditure - burning calories. The amounts tested, however, were not realistic for most people in the U. S. population, Mattes said.
The current study measured the spice's effects using quantities of red pepper - 1 gram or half a teaspoon - that are acceptable for many consumers. Other studies also have looked at consumption via a capsule, but Ludy and Mattes' study demonstrated that tasting the red pepper may optimize its effects. The findings are published in Physiology & Behavior.
This study used ordinary dried, ground cayenne red pepper. Cayenne is a chili pepper, which is among the most commonly consumed spices in the world. Most, but not all, chili peppers contain capsaicin.
Twenty-five non-overweight people - 13 who liked spicy food and 12 who did not - participated in the six-week study. The preferred level of pepper for each gro
