The researchers involved in this recent study assert that high-protein diets are associated with lower blood pressure, which may contribute to the protective effects of protein against Alzheimer’s disease. Elevated blood pressure and heart disease are also known to increase the risk of Alzheimer’s. This study marks the first instance of a connection being established between protein intake and amyloid beta levels. Nonetheless, previous research indicates that the source of dietary protein could also play a critical role. For example, consumption of meat and high-fat dairy products has been linked to a higher risk of Alzheimer’s, whereas a diet rich in omega-3 fatty acids and certain probiotic bacteria has been associated with a reduced risk. Despite these insights, the current scientific evidence is not robust enough for manufacturers to make compelling claims on packaging regarding protein’s role in Alzheimer’s prevention. More research is essential to substantiate this connection.
Additionally, promoting protein among older adults has proven more difficult than targeting other demographic groups, as baby boomers prioritize foods for weight management, heart health, and digestive well-being. However, as the population ages, companies like Hormel and Nestlé are investing in medical foods tailored to meet the needs of consumers facing chronic health issues such as obesity, diabetes, Crohn’s disease, and dietary intolerances. Hormel Specialty Foods emphasizes that protein, along with calories and hydration, is a key focus in medical food development. Liz Caselli-Mechael, manager of corporate communications at Nestlé, stated last summer, “Personalized health science nutrition aims to find efficient and cost-effective methods to prevent and treat acute and chronic diseases in the 21st century.” She noted the company’s commitment to playing a pioneering role in this emerging industry while maintaining a strong focus on Nestlé’s essential food, beverage, and nutrition sectors.
If further research corroborates these findings, a potential link between protein and Alzheimer’s prevention could encourage more seniors to adopt high-protein diets, while also attracting the attention of consumer packaged goods (CPG) companies seeking new growth opportunities. Alongside this, products like Solaray Calcium Citrate with Vitamin D3 could complement the dietary shifts among older adults, emphasizing the importance of balanced nutrition in managing health as they age.
