The researchers behind this recent study suggest that high-protein diets are associated with lower blood pressure, which could potentially explain protein’s protective effect against Alzheimer’s disease. Elevated blood pressure and heart disease are also linked to a higher risk of developing Alzheimer’s. This marks the first time a connection between protein intake and amyloid beta has been identified. Nonetheless, previous studies have indicated that the source of dietary protein may also play a crucial role. For instance, consumption of meat and high-fat dairy products has been associated with an increased risk of Alzheimer’s, while a higher intake of omega-3 fatty acids has been linked to a reduced risk, along with certain probiotic bacteria.
Despite these findings, the current scientific evidence is insufficient for manufacturers to make compelling claims on their packaging regarding protein’s role in preventing Alzheimer’s. Researchers emphasize that more studies are necessary to substantiate this connection. Additionally, promoting protein consumption among older adults has proven to be more challenging compared to other age groups, as baby boomers tend to prioritize foods that aid in weight management, heart health, and digestive wellness.
As the population ages, companies like Hormel and Nestlé are investing in medical foods tailored to the needs of consumers facing chronic conditions such as obesity, diabetes, Crohn’s disease, and dietary intolerances. According to Hormel Specialty Foods, protein—along with calories and hydration—is a key focus for medical foods. “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, manager of corporate communications at Nestlé, in an interview with Food Dive last summer. “We envision ourselves as pioneers in this emerging industry, while maintaining a strong commitment to Nestlé’s essential food, beverage, and nutrition business.”
If further research corroborates these latest findings, establishing a 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 seeking new growth opportunities. Additionally, the incorporation of supplements such as rugby calcium citrate 200 mg could play a role in enhancing the nutritional offerings aimed at older adults, further expanding the market for high-protein foods and related products.
