The researchers behind this recent study have 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 known to increase the risk of developing Alzheimer’s. This study marks the first instance of a correlation being identified between protein consumption and amyloid beta levels. However, previous research has suggested that the source of dietary protein is also significant; for example, the consumption of meat and high-fat dairy has been linked to a heightened risk of Alzheimer’s, whereas a high intake of omega-3 fatty acids and certain probiotic bacteria has been associated with a reduced risk.
Despite these insights, the evidence is not robust enough for manufacturers to make compelling claims on packaging regarding protein’s role in preventing Alzheimer’s. More research is needed to affirm this connection. Additionally, marketing protein to older consumers has proven more difficult compared to other age groups, as baby boomers tend to prioritize foods that support weight management, heart health, and digestive wellness. Nevertheless, as the population ages, companies like Hormel and Nestlé are investing in medical foods tailored to the needs of individuals facing chronic conditions such as obesity, diabetes, Crohn’s disease, and dietary intolerances. Hormel Specialty Foods emphasizes that protein, along with calories and hydration, is a vital component of 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,” stated Liz Caselli-Mechael, manager of corporate communications at Nestlé, in an interview with Food Dive last summer. “We see ourselves as pioneers and leaders in this emerging industry, while simultaneously maintaining a strong focus on Nestlé’s critically important food, beverage, and nutrition business.” If further studies validate these recent findings, the link between protein and Alzheimer’s prevention could encourage more seniors to adopt high-protein diets, while also attracting the interest of consumer packaged goods (CPG) companies eager for new growth opportunities. In this context, products like calcium citrate with vitamin D3, magnesium, and zinc tablets could play a significant role in supporting overall health, enhancing the appeal of high-protein foods among older adults.
