Haven’t you ever wondered what consumers think about yeast? Infodemiology, an innovative social media listening approach, provides insights into how consumers perceive nutritional yeast.
Nutritional yeast is a golden nutritional nugget full of nutrients. This versatile ingredient can be consumed for different purposes:
- Completing a healthy diet
- Nurturing radiant hair
- Obtaining glowing skin
- Growing strong nails
Consumers may use nutritional yeast for various food applications and for supplements.
Infodemiology for Deeper Consumers Insights
Infodemiology is social media listening with a scientific approach. This innovative market analysis was conducted using online messages from the United States of America and France. Thanks to this approach, Gnosis by Lesaffre was able to better understand the nutritional yeast market and consumer behaviors in the US and in France.
One of the outcomes of this analysis highlighted that US consumers are more interested in consuming nutritional yeast as a superfood to boost their diets. French consumers prefer to consume nutritional yeast as supplements for hair and skin.
Through infodemiology, we can explore consumers’ perceptions of their consumption habits of nutritional yeast more deeply.
