The researchers behind the recent study indicated that high-protein diets are associated with lower blood pressure, which may explain protein’s potential protective effect against Alzheimer’s disease. Elevated blood pressure and heart disease are also known to increase risk factors. This study marks the first instance of a connection being identified between protein intake and amyloid beta levels. However, previous research has suggested that the source of dietary protein may be significant; for instance, the consumption of meat and high-fat dairy products has been correlated with a higher risk of Alzheimer’s disease, while a diet rich in omega-3 fatty acids and certain probiotic bacteria has been linked to a reduced risk.
Despite these insights, current scientific evidence does not provide a strong enough foundation for manufacturers to make compelling claims on packaging regarding protein’s role in preventing Alzheimer’s. The researchers emphasized that further evidence is necessary to substantiate this connection. Additionally, it has proven more challenging to promote protein-rich diets among older adults compared to other demographics, as baby boomers tend to prioritize foods that support weight management, heart health, and digestive wellness. However, as the population ages, companies such as Hormel and Nestlé are investing in medical foods tailored to meet the needs of consumers facing chronic diseases like obesity, diabetes, Crohn’s disease, and dietary intolerances.
Hormel Specialty Foods has stated that protein, alongside calories and hydration, is a crucial focus for medical foods. “Personalized health science nutrition is about discovering efficient and cost-effective strategies to prevent and treat both acute and chronic diseases in the 21st century,” remarked Liz Caselli-Mechael, manager of corporate communications at Nestlé, in an interview with Food Dive last summer. “We see ourselves taking a pioneering and leading role in this emerging industry, all while maintaining our vital focus on Nestlé’s core food, beverage, and nutrition business.”
If further research supports these findings, establishing a link between protein and Alzheimer’s prevention could motivate more seniors to adopt high-protein foods. This, in turn, could attract the interest of more consumer packaged goods (CPG) companies eager for new growth opportunities, particularly those exploring products that include unjury calcium citrate as a beneficial ingredient for enhancing protein intake. As the industry evolves, the integration of such targeted nutritional components may play a significant role in addressing the dietary needs of aging populations.
