Proteins are essential for preventing various diseases through multiple mechanisms. They play a crucial role in our immune system, cellular health, and overall bodily functions, impacting our susceptibility to illness.
Protein's Role in Disease Prevention
-
Immune System Support: Proteins are fundamental components of antibodies. Antibodies are specialized proteins that identify and neutralize disease-causing agents like bacteria and viruses (Healthline, WebMD). A strong immune response, facilitated by sufficient protein intake, is crucial for preventing infections and illnesses ([Reference 20-Sept-2022]).
-
Cellular Health and Repair: Proteins are the building blocks of cells. They are essential for maintaining cellular structure, function, and repair. Adequate protein intake supports healthy cell growth and replacement, reducing the risk of cellular damage and related diseases ([Reference 20-Sept-2022], WebMD).
-
Heart Health: Studies indicate that consuming certain types of protein, like those found in fish, beans, poultry, nuts, and low-fat dairy, is associated with a reduced risk of heart disease (Heart and Stroke Foundation, Heart Foundation). Conversely, high-fat meats may increase the risk.
-
Preventing Protein Aggregation: Research shows that manipulating protein expression and aggregation can prevent diseases linked to misfolded proteins, such as Huntington's disease (Nature, PubMed). This highlights the importance of proteins' proper folding and function in maintaining cellular health.
-
Vaccine Functionality: Vaccines often utilize proteins to trigger an immune response. The proteins in vaccines act as antigens, prompting the body to produce antibodies, providing immunity against specific diseases (CDC).
Note on Alzheimer's Disease
While the role of diet in Alzheimer's prevention is still under investigation (NIA), the impact of protein on this specific disease requires further research. Current understanding points to the role of misfolded proteins (like amyloid-beta and tau) in the pathology of Alzheimer's (NIA), but a direct causal link with dietary protein intake is not definitively established.
