On the physical level, circulatory problems and heart disease are caused by a build-up of impurities in the blood, the lymph, the tissue fluid that connects cells (connective tissue), and the walls of the blood vessels (capillaries and arteries). Of all the foods, protein from animal sources has the most congesting effects. Since the human body can only utilize a very small amount of the protein contained in meat, eggs, fish, or cheese, etc., much of the unused protein is passed via the blood stream into the connective tissues.

When too many proteins enter the connective tissue it thickens to the consistency of jelly. This obstructs the cells’ nutrient supply and removal of metabolic waste materials. To make the tissue fluid thin again the excessive proteins are stored as collagen in the basement membranes of the capillaries and arteries. Once their storage capacity for protein is exhausted the blood pressure may rise and the blood becomes thicker. The cells of the body begin to suffer malnutrition and, unable to remove all their metabolic waste products, the level of impurities in the body’s organs, tissues and cells starts to rise. This greatly adds to the workload of the heart, cuts down oxygen supply and the body as a whole becomes tired more easily.

Since the blood pressure is naturally higher in the arteries close to the heart, hardened coronary arteries are particularly vulnerable to injury. Any wounds or cracks that occur in these arteries can be life threatening and are consequently patched up by the body with special glue-like blood chemicals and cholesterol. In the long-term these first aid measures, however, may lead to total occlusion of the heart arteries, which starve the heart muscles of oxygen and trigger a heart attack. All this generates anxiety, insecurity, anger, depression, or other stressful emotions.
