Heart disease and stroke are forms of cardiovascular disease that are generally caused by atherosclerosis, a buildup of plaque in the arteries over many years. This plaque buildup can restrict blood flow and cause heart attacks, strokes, or gangrene depending on the location. Risk factors for cardiovascular disease include smoking, diabetes, high blood pressure, high cholesterol, obesity, poor diet, lack of exercise, and exposure to pollution. Early warning signs can include numbness, tingling, cold fingers/toes, and swelling. Coconut oil is a healthy fat that may help maintain cholesterol levels and immunity while promoting proper digestion.
