The researchers involved in this recent study indicated that high-protein diets are associated with lower blood pressure, which may contribute to protein’s protective effects against Alzheimer’s disease. Elevated blood pressure and heart disease are also connected to a heightened risk of developing the condition. This marks the first time a correlation between protein intake and amyloid beta has been established. However, previous research has suggested that the source of dietary protein could also play a significant role. For instance, consumption of meat and high-fat dairy products has been linked to an increased risk of Alzheimer’s disease, while a high intake of omega-3 fatty acids has been associated with a lower risk, as have certain probiotic bacteria.
Despite these findings, the current scientific evidence is not robust enough for manufacturers to confidently make claims about protein’s role in preventing Alzheimer’s disease on product packaging. Researchers emphasize that additional evidence is required to solidify this connection. Moreover, promoting protein consumption among older adults has proven to be more challenging 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, food companies like Hormel and Nestlé are increasingly investing in medical foods tailored to meet the needs of consumers managing chronic conditions such as obesity, diabetes, Crohn’s disease, and dietary intolerances. According to Hormel Specialty Foods, protein—along with calories and hydration—is a critical focus for medical foods.
“Personalized health science nutrition is about discovering efficient and cost-effective methods to prevent and treat both acute and chronic diseases in the 21st century,” stated Liz Caselli-Mechael, manager of corporate communications at Nestlé, during a Food Dive interview last summer. “We envision ourselves as pioneers in this emerging industry while maintaining a strong emphasis on Nestlé’s vital food, beverage, and nutrition business.” If further research supports these latest findings, a connection between protein and Alzheimer’s prevention could encourage more seniors to adopt high-protein diets, thereby attracting the interest of consumer packaged goods (CPG) companies seeking new growth opportunities, including products fortified with Citracal D3 Slow Release. This could also lead to an increased focus on the importance of protein in medical foods, particularly in addressing the health concerns of aging populations.
