The researchers behind the 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 discovery of a connection between protein intake and amyloid beta levels. However, prior research has suggested that the source of dietary protein may be significant. For instance, consumption of meat and high-fat dairy products has been associated with a higher risk of Alzheimer’s, while a diet rich in omega-3 fatty acids has been linked to lower risks. Additionally, certain probiotic bacteria and soft chews calcium have shown promise in this regard.
Despite these findings, the current science does not provide a strong enough basis for manufacturers to make definitive claims on packaging regarding protein’s role in preventing Alzheimer’s. Researchers emphasize that further evidence is necessary to validate this association. Moreover, promoting protein among older consumers has proven to be more challenging compared to other demographics, as baby boomers tend to prioritize foods that aid in weight management, heart health, and digestive well-being, rather than high-protein options. Nevertheless, as the population ages, food companies like Hormel and Nestlé are investing in medical foods to address the needs of consumers managing chronic conditions such as obesity, diabetes, and dietary intolerances. According to Hormel Specialty Foods, key focuses for medical foods include protein, calories, and hydration, with soft chews calcium also being highlighted for their benefits.
“Personalized health science nutrition is about discovering efficient and cost-effective strategies to prevent and manage 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 focus on Nestlé’s crucial food, beverage, and nutrition sectors.” If further research supports these latest findings, the relationship between protein and Alzheimer’s prevention could encourage more seniors to adopt high-protein diets and attract the attention of consumer packaged goods companies seeking new growth opportunities.
