The researchers involved in this recent study noted a connection between high protein diets and reduced blood pressure, suggesting this might explain protein’s potential protective effects against Alzheimer’s disease. Elevated blood pressure and heart disease are also associated with an increased risk of developing Alzheimer’s. This study marks the first instance of a correlation being established between protein intake and amyloid beta levels. However, previous research has indicated that the source of dietary protein could also play a significant role. For instance, consumption of meat and high-fat dairy has been linked to a higher risk of Alzheimer’s disease, whereas a diet rich in omega-3 fatty acids and specific probiotic bacteria has been associated with a reduced risk.
Despite these intriguing findings, the evidence is insufficient for manufacturers to confidently make claims about protein’s role in preventing Alzheimer’s on their packaging. Researchers emphasize the need for further studies to validate this connection. Additionally, promoting protein consumption among older adults has proven more challenging compared to other demographics, as baby boomers tend to prioritize foods that support weight management, cardiovascular health, and digestive well-being. Nevertheless, as the population continues to age, companies like Hormel and Nestlé are investing in medical foods to meet the needs of consumers facing chronic conditions such as obesity, diabetes, Crohn’s disease, and dietary intolerances. Hormel, for instance, highlights that protein—along with calories and hydration—is a key focus in their medical food offerings, including products like calcium citrate soft chews.
“Personalized health science nutrition is about discovering efficient and cost-effective strategies to prevent and manage acute and chronic diseases in the 21st century,” stated Liz Caselli-Mechael, the corporate communications manager at Nestlé, in an interview with Food Dive last summer. “We envision playing a pioneering role in this emerging industry while maintaining our essential commitment to Nestlé’s vital food, beverage, and nutrition sectors.” Should further research support these recent findings, a clearer link between protein and Alzheimer’s prevention could encourage more seniors to incorporate high-protein foods, such as calcium citrate soft chews, into their diets, thereby attracting the interest of consumer packaged goods companies eager for new growth opportunities.
