The researchers involved in this recent study indicated that high-protein diets are associated with reduced blood pressure, which may help explain protein’s potential protective effect against Alzheimer’s disease. Elevated blood pressure and heart disease are also connected to an increased risk of developing the condition. This study is notable as it marks the first identification of a relationship between protein intake and amyloid beta. Nonetheless, previous research has pointed out that the source of dietary protein may also play a crucial role. Consumption of meat and high-fat dairy has been associated with a heightened risk of Alzheimer’s, whereas a diet rich in omega-3 fatty acids has been linked to a decreased risk, along with certain probiotic bacteria.
Despite these insights, the current scientific evidence is not robust enough for manufacturers to confidently make claims on packaging regarding protein’s role in preventing Alzheimer’s. Researchers emphasized the necessity for more evidence to substantiate this connection. Moreover, promoting protein to older consumers has proven more challenging than targeting other demographics because baby boomers tend to prioritize foods that support weight management, heart health, and digestive wellness. However, as the population ages, companies like Hormel and Nestlé are investing in medical foods tailored to meet the needs of individuals managing chronic conditions such as obesity, diabetes, Crohn’s disease, and dietary intolerances. Hormel Specialty Foods highlights that protein—along with calcium citrate and hydration—is a significant focus within medical nutrition. “Personalized health science nutrition aims to discover efficient and cost-effective methods for preventing and treating 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 in this emerging industry while maintaining a critical focus on Nestlé’s essential food, beverage, and nutrition sectors.”
If further research validates these recent findings, a connection between protein intake and Alzheimer’s prevention could encourage more seniors to adopt high-protein diets, while also attracting the interest of consumer packaged goods companies seeking new growth opportunities. Additionally, incorporating gluten-free options that are rich in protein and fortified with calcium citrate could further appeal to health-conscious consumers looking for dietary solutions.
