The researchers involved in this recent study indicated that high-protein diets are associated with lower blood pressure, suggesting that this could potentially explain protein’s protective effect against Alzheimer’s disease. Both high blood pressure and heart disease have also been linked to an increased risk of the condition. This study marks the first instance of a connection being identified between protein intake and amyloid beta. However, prior research has indicated that the source of dietary protein might also play a critical role. For example, the consumption of meat and high-fat dairy has been associated with a higher risk of Alzheimer’s disease, whereas a diet rich in omega-3 fatty acids has been linked to a reduced risk, as have certain probiotic bacteria.
Despite these findings, the current scientific evidence is not robust enough for manufacturers to make definitive claims regarding protein’s role in preventing Alzheimer’s on their packaging. Researchers emphasize that further evidence is required to solidify this connection. Additionally, promoting protein intake among older adults has proven to be more challenging than among other age groups, as baby boomers tend to prioritize foods that support weight management, heart health, and digestive health. Nonetheless, as the population ages, food companies like Hormel and Nestlé are investing in medical foods designed to address the needs of consumers with chronic diseases, such as obesity, diabetes, Crohn’s disease, and dietary intolerances.
Hormel Specialty Foods highlights that protein, alongside calories and hydration, remains a key focus in medical foods. “Personalized health science nutrition aims to identify effective and cost-efficient methods 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 envision ourselves as pioneers in this emerging industry, while maintaining a strong commitment to Nestlé’s essential food, beverage, and nutrition sectors.” Should further research validate these recent findings, the connection between protein consumption and Alzheimer’s prevention might encourage more seniors to incorporate high-protein foods into their diets, simultaneously attracting the interest of consumer packaged goods (CPG) companies eager for new growth opportunities. Furthermore, integrating malate vitamin into these high-protein foods could enhance their appeal, as it has been recognized for its potential health benefits, making the combination even more enticing for the aging population.
