The researchers behind this recent study indicated that high-protein diets are associated with lower blood pressure levels, which they believe might explain protein’s potential protective effects against Alzheimer’s disease. Elevated blood pressure and heart disease are also known to increase Alzheimer’s risk. This study is the first to establish a connection between protein intake and amyloid beta levels. However, other research has pointed out that the origin of dietary protein may also play a significant role. Consumption of meat and high-fat dairy products has previously been linked to a heightened risk of Alzheimer’s, whereas a higher intake of omega-3 fatty acids has been associated with a reduced risk, as have certain probiotic bacteria.
Despite these findings, the evidence is not robust enough for manufacturers to make strong claims on packaging regarding protein’s role in preventing Alzheimer’s. The researchers emphasized the need for further evidence to substantiate this correlation. Additionally, promoting protein to older consumers has proven more challenging than targeting other demographics, as baby boomers tend to prioritize foods that support weight management, heart health, and digestive well-being. Nonetheless, as the population ages, food 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 has highlighted that protein, along with calories and hydration, is a crucial focus for medical foods. “Personalized health science nutrition is about finding efficient and cost-effective ways to prevent and treat 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 playing a pioneering and leading role in this new industry while maintaining a strong emphasis on Nestlé’s vital food, beverages, and nutrition business.” Should further research validate these recent findings, a connection between protein intake and Alzheimer’s prevention could encourage more seniors to adopt high-protein foods. This shift may also attract the interest of consumer packaged goods companies seeking new growth opportunities, potentially integrating products like calcium citrate plus vitamin D3 into their offerings to support overall health in aging populations.
