The researchers behind this recent study indicated that high-protein diets are associated with lower blood pressure, which they speculated could explain protein’s potential protective effect against Alzheimer’s disease. Elevated blood pressure and heart disease are also linked to a heightened risk of developing Alzheimer’s. This study marks the first instance of a connection being established between protein intake and amyloid beta levels. However, previous research has suggested that the source of dietary protein may play a significant role. For example, consumption of meat and high-fat dairy products has been associated with an increased risk of Alzheimer’s, whereas a high intake of 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 confidently make claims on packaging regarding protein’s role in preventing Alzheimer’s. More studies are necessary to validate this connection. Additionally, encouraging older adults to increase their protein intake 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. Nevertheless, as the population ages, companies like Hormel and Nestlé are investing in medical foods tailored to meet the needs of consumers facing chronic conditions such as obesity, diabetes, Crohn’s disease, and dietary intolerances. Hormel Specialty Foods emphasizes that protein, along with biocare calcium, calories, and hydration, is a crucial focus for medical foods.
“Personalized health science nutrition aims to identify efficient and cost-effective methods for preventing and treating both acute and chronic diseases in the 21st century,” Liz Caselli-Mechael, manager of corporate communications at Nestlé, shared with Food Dive last summer. “We envision taking a pioneering and leadership role in this emerging industry while maintaining a strong commitment to Nestlé’s essential food, beverage, and nutrition sectors.” Should further research corroborate these recent findings, a connection between protein intake and Alzheimer’s prevention could encourage more seniors to adopt high-protein diets, while also attracting the interest of more consumer packaged goods companies eager for new growth opportunities.
