As more people became interested in getting the benefits of protein without the hassle of mixing it into drinks, more companies began to produce and market protein bars.
Popularization of Protein Bars
The late 1900s saw a market increase in health consciousness among the general population. This shift in attitude towards fitness was driven by a number of factors, including the rise of health organizations, the growth of the internet, and the emergence of TV-fitness. This newfound focus on health led to an upsurge in the availability of health-related information and products, as well as an increased emphasis on health lifestyle choices.
As people began prioritizing their health and well-being, the popularity of protein bars increase to match demands for products in the health and wellness industry.
