The researchers behind this recent study indicated that high protein diets are associated with lower blood pressure, which could be a potential reason for protein’s protective effect against Alzheimer’s disease. Increased blood pressure and heart disease are also linked to a heightened risk of developing the condition. This study marks the first instance in which a connection between protein intake and amyloid beta has been identified. However, previous research suggests that the source of dietary protein might also play a significant role. Consumption of meat and high-fat dairy has been associated with a higher risk of Alzheimer’s disease, while a diet rich in omega-3 fatty acids and certain probiotic bacteria has been linked to a reduced risk.
Despite these findings, the current scientific evidence is insufficient for manufacturers to make strong claims on packaging regarding the role of protein in Alzheimer’s prevention. Researchers have emphasized the need for further evidence to substantiate this connection. Additionally, promoting protein-rich foods among older consumers has proven more challenging compared to younger demographics, as baby boomers tend to prioritize nutrition that supports weight management, heart health, and digestive wellness. Nevertheless, as the population ages, food companies like Hormel and Nestlé are investing in medical foods to cater to consumers dealing with chronic conditions such as obesity, diabetes, Crohn’s disease, and dietary intolerances. Hormel Specialty Foods has highlighted that protein, alongside calories and hydration, is a critical focus for their medical food products.
Liz Caselli-Mechael, the manager of corporate communications at Nestlé, stated to Food Dive last summer, “Personalized health science nutrition is about finding efficient and cost-effective ways to prevent and treat acute and chronic diseases in the 21st century.” She added that the company envisions playing a pioneering role in this emerging industry while maintaining a strong emphasis on Nestlé’s essential food, beverage, and nutrition sectors.
If further studies support these new findings, the connection between protein consumption and Alzheimer’s prevention could encourage more seniors to incorporate high-protein foods into their diets, potentially attracting the attention of consumer packaged goods (CPG) companies eager to explore new growth opportunities. In this context, products like Lamberts Calcium Citrate may also gain traction, reinforcing the importance of a balanced diet rich in essential nutrients alongside protein.
