The researchers involved in this recent study indicated that high-protein diets are associated with lower blood pressure, which may contribute to protein’s protective effects against Alzheimer’s disease. Elevated blood pressure and heart disease are also linked to an increased risk of Alzheimer’s. This study marks the first time a connection between protein intake and amyloid beta levels has been identified. However, previous studies have suggested that the source of dietary protein might play a significant role. For instance, the consumption of meat and high-fat dairy has been associated with a heightened risk of Alzheimer’s, whereas a high intake of omega-3 fatty acids and certain probiotic bacteria has been connected to a reduced risk.
Despite these insights, current scientific evidence is insufficient for manufacturers to make compelling claims on packaging regarding protein’s role in preventing Alzheimer’s. More research is necessary to substantiate this connection. Additionally, promoting protein consumption among older adults has proven to be more challenging compared to other demographics, as baby boomers tend to prioritize foods for weight management, heart health, and digestive well-being. Nevertheless, as the population continues to age, food companies like Hormel and Nestlé are investing in medical foods designed 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 calories and hydration, is a crucial focus for medical foods.
“Personalized health science nutrition aims to find efficient and cost-effective strategies to prevent and treat acute and chronic diseases in the 21st century,” stated Liz Caselli-Mechael, manager of corporate communications at Nestlé, during an interview with Food Dive last summer. “We see ourselves as pioneers and leaders in this emerging industry, all while maintaining a strong focus on Nestlé’s vital food, beverage, and nutrition sectors.” Should further research validate these findings, the association between protein and Alzheimer’s prevention could encourage more seniors to adopt high-protein diets, potentially attracting the interest of consumer packaged goods (CPG) companies eager for new growth opportunities. Additionally, incorporating supplements like calcium citrate from Puritan’s Pride may enhance the nutritional profile of high-protein foods, further benefiting those looking to improve their overall health.
