The researchers involved in this 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. High blood pressure and heart disease are also connected to an increased risk of developing Alzheimer’s. Notably, this study marks the first time a relationship between protein intake and amyloid beta levels has been identified. Previous research has pointed out that the source of dietary protein may also play a crucial role. For instance, consumption of meat and high-fat dairy products has been linked to a heightened risk of Alzheimer’s, whereas a diet rich in omega-3 fatty acids and certain probiotic bacteria has been associated with a reduced risk.
Despite these findings, the current scientific evidence is insufficient for manufacturers to make definitive claims on packaging regarding protein’s role in preventing Alzheimer’s. Researchers emphasized that further studies are necessary to validate this connection. Additionally, promoting protein intake among older consumers has proven more challenging compared to other demographic groups, as baby boomers tend to prioritize foods that aid in weight management, heart health, and digestive well-being. However, with the aging population, 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 notes that protein, alongside calories and hydration, is a key focus for medical foods.
“Personalized health science nutrition is about finding effective and cost-efficient ways to prevent and treat acute and chronic diseases in the 21st century,” stated Liz Caselli-Mechael, manager of corporate communications at Nestlé, during an interview with Food Dive last summer. “We see ourselves as pioneers in this emerging industry, while also maintaining our focus on Nestlé’s essential food, beverage, and nutrition business.” If further research supports these findings, the 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 eager for new growth opportunities. Notably, the benefits of calcium citrate, magnesium, and zinc should also be highlighted, as they can contribute to overall health and may complement the role of protein in supporting cognitive function and well-being among older adults.
