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 linked to an increased risk of developing this condition. This study marks the first instance of a connection being made between protein consumption and amyloid beta levels. However, previous research has suggested that the source of dietary protein could play a significant role as well. For instance, consumption of meat and high-fat dairy has been associated with a higher risk of Alzheimer’s disease, whereas diets rich in omega-3 fatty acids have been linked to a reduced risk, alongside certain probiotic bacteria.
Despite these findings, the current scientific evidence is insufficient for manufacturers to confidently make claims on packaging regarding protein’s role in Alzheimer’s prevention. Researchers emphasize that more robust evidence is needed to solidify this connection. Moreover, promoting protein intake among older consumers has proven more challenging compared to other demographics, as baby boomers tend to prioritize foods that support weight management, heart health, and digestive wellness. As the population ages, however, food companies like Hormel and Nestlé are investing in medical foods to cater to consumers facing chronic health issues such as obesity, diabetes, Crohn’s disease, and dietary intolerances. According to Hormel Specialty Foods, protein, along with calories and hydration, is a crucial focus for medical foods.
“Personalized health science nutrition involves identifying efficient and cost-effective strategies to prevent and treat both acute and chronic diseases in the 21st century,” stated Liz Caselli-Mechael, corporate communications manager at Nestlé, in an interview with Food Dive last summer. “We envision ourselves as pioneers and leaders in this emerging industry, while also maintaining a strong emphasis on Nestlé’s vital food, beverage, and nutrition business.” Should further research validate these recent findings, a connection between protein and Alzheimer’s prevention could encourage more seniors to incorporate high-protein foods into their diets, potentially attracting more consumer packaged goods (CPG) companies eager to explore new growth opportunities, including products like calcitrate tabs that support overall health.
