The third dimension of flavor: A chemesthetic approach to healthier eating (a review)

Abstract

AbstractObesity and obesity‐related illness are an increasingly prevalent problem globally, especially in Western society. One of the largest contributing factors to the obesity pandemic is the modern food environment and food culture. It is necessary to identify and develop strategies to increase the sensory appeal of healthy food and beverage options in order to provide healthy options to consumers without sacrificing the fundamental sensory enjoyment of eating. Since flavor is the largest driver of food intake and choice, it follows that flavor ought to be part of the solution. This paper reviews the potential of chili pepper or capsaicin (the pungent component of chili pepper) as a healthy eating strategy, by increasing energy expenditure, decreasing intake, decreasing eating rate, and enhancing flavor and satisfaction. Furthermore, we suggest a holistic chemesthetic approach to weight management, by using the sensory impact of trigeminal stimulation (spiciness or heat) in foods, rather than medicinally, in order to cross‐modally enhance tastes and odors, increase perceived complexity and overall flavor, increase sensory satisfaction, and decrease salt and caloric intake. Future research directions are discussed.Practical ApplicationIt is necessary to provide strategies, such as trigeminal stimulation, global culinary practices, and flavor complexity, to consumers to maintain sensory satisfaction derived from healthier foods and beverages. Healthy does not have to equate to flavorless or unappealing, although it is commonly believed that unhealthy = tasty in the United States. Food can be both healthy and flavorful if we harness our collective sensory and culinary knowledge to generate a satisfying sensory experience. Incorporation of trigeminal stimulation, the third dimension of flavor in addition to taste and aroma, such as capsaicin or hot pepper, is an excellent example of drawing from global cuisines, increasing flavor complexity, and increasing overall flavor impression, in order to boost the sensory appeal, nutrition content, and nutrient absorption of healthy foods and to promote healthier eating.
