Charting The Taste & Smell Landscape
Research Team: Mindy Yang, Rachel S. Herz, Ph.D., and Martha R. Bajec, Ph.D.
Taste and smell disorders are a significant yet often overlooked public health challenge, affecting millions worldwide. Despite their profound impact on healthspan and quality of life, there is a lack of unified, benchmarked data to fully understand the scope, implications, and economic effects of these conditions.
The growing prevalence of taste and smell impairments underscores the urgent need for action. These disorders not only diminish sensory experiences but also pose serious risks to physical and mental health. Conditions such as anosmia and hypersensitivity can lead to malnutrition, social isolation, depression, and reduced safety awareness, significantly impacting individuals’ healthspan and well-being.
Despite the critical importance of these senses, research in this area remains severely underfunded. According to The National Institute on Deafness and Other Communication Disorders (NIDCD), taste and smell research receives the least funding among health sciences. This funding gap hinders the development of effective diagnostic tools, interventions, and support services for those affected.
The absence of standardized data on taste and smell disorders further complicates efforts to accurately diagnose and manage these conditions, resulting in suboptimal care. Additionally, policymakers lack the robust data needed to formulate effective public health strategies and allocate resources appropriately.
Comprehensive research is essential to establish a benchmark understanding of these disorders. By systematically collecting data on their prevalence, causes, healthspan impact, public awareness, and economic implications, evidence-based interventions can be developed. This research will improve healthcare delivery, inform policy, and drive innovation to enhance nutrition and quality of life for those affected by taste and smell disorders.

WTSA’s inaugural Taste & Smell research initiative is inspired by a previous survey-style study by Rachel S. Herz, Ph.D. and Martha R. Bajec, Ph.D., the original team behind "Your Money or Your Sense of Smell? A Comparative Analysis of the Sensory and Psychological Value of Olfaction," published in 2022. This enhanced and dynamic version, once again developed with Dr. Herz and Dr. Bajec, is spearheaded by WTSA Co-Founder and Sensory Expert Mindy Yang.

PHASE I
Our primary objective is to gather comprehensive data on taste and smell disorders, focusing on understanding healthspan, economic impact, and related factors.
The survey, meticulously designed by our team of sensory experts, will capture a wide range of behavioral, emotional, and sensory data, including sensory disorders. Participants will be asked to reflect on their taste and smell perceptions, any changes they have noticed over time, and how these changes have affected their lives—socially, economically, and psychologically. The survey will identify the broad spectrum of taste and smell disorders, their duration and severity, and potential links to other health conditions, behaviors, and economic impact.
Additionally, we will assess participants’ engagement with treatments or coping strategies, offering valuable insights into how individuals are managing sensory loss and where gaps in care or support may exist.
By the conclusion of Phase I in December 2024, we expect to have a robust dataset, which will undergo thorough analysis to uncover trends and patterns. These findings will play a pivotal role in advancing sensory research and will be shared widely in Spring 2025 through peer-reviewed publications, conferences, and outreach initiatives to raise awareness of the significance of taste and smell disorders.

KEY COMPONENTS
Survey Design:
This dynamic survey is designed to capture valuable data on taste and smell experiences, including the identification of related disorders.
Data Collection:
Participants aged 18 and older, residing in the United States, will anonymously complete the survey, providing responses about their taste and smell experiences as well as relevant demographic information. Data collection will continue through December 2024.
Data Analysis:
Once data collection is complete, we will analyze the responses to identify patterns, trends, and associations related to taste and smell disorders. Advanced statistical techniques will be applied to uncover meaningful insights.
Publication and Dissemination:
Findings from Phase I will be shared through IRB submissions, peer-reviewed publications, conference presentations, and community outreach efforts to raise awareness about taste and smell disorders and their impact on daily life.

SCALING FOR THE FUTURE
WTSA seeks to lay the foundation for future research, including longitudinal studies and the creation of micro-fund grants to support innovative projects aimed at improving the quality of life for individuals affected by taste and smell disorders.
By systematically gathering comprehensive data on these disorders, our goal is to advance scientific understanding and inform the development of targeted interventions and support services for those impacted.
Addressing the current lack of unified, benchmarked data is essential to mitigating the profound effects of taste and smell disorders on individuals’ health and well-being. Through focused research efforts, WTSA aims to drive progress in developing better support systems for those affected and to inspire innovation that enhances healthspan and addresses the economic impact of sensory impairments.
