13. Prevent blood pressure increase caused by angiotensin converting enzyme released from the kidney (another blood pressure lowering effect);
14. As a barrier to protect brain cells, prevent the formation of amyloid beta protein, glutamate toxicity and free radical attack, thus preventing Alzheimer's disease;
