What is the human body’s most important system? Answer: they’re all equally important, but when we take special care of our cardiovascular and digestive health, we have a good chance at a long, relatively disease-free life. This collection of seven video clips covers many of the basic concerns and illnesses related to heart and gastric health. Each clip averages four minutes in length.
Video clips include…
• Cholesterol: The heart is the engine of the body, and one important factor in keeping it healthy is cholesterol control. Cholesterol is a lipid or fat that is made in the liver from fatty foods. Cholesterol is carried in the blood, and we all need it to keep healthy—but on the other hand, too much cholesterol circulating in the bloodstream can be dangerous.
• Diabetes: Diabetes is a chronic disease that affects millions of people. Normally a hormone called insulin, which is made by the pancreas, takes glucose or sugar from the bloodstream to the various cells of the body. Diabetes occurs when the level of glucose in the blood becomes too high.
• Obesity: Numerous social factors, from technology to entertainment, have all helped to create an obese society. Obesity means an unhealthy amount of body fat and is measured using the body mass index, or BMI, calculated by using weight and height. A BMI higher than 30 is classified as obese.
• High Blood Pressure: One of the consequences of modern lifestyle is the “silent killer”—high blood pressure, otherwise known as hypertension. Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps blood through the body. If this pressure rises and stays high over time, it can damage the body in many ways.
• Malnutrition: Malnutrition is not only prevalent in developing countries or during famine. It is vital that everyone, especially children, maintain a good balanced diet, but every society struggles with this very serious problem.
• Cholera: Our small intestines absorb all the nutrients we ingest. Diseases like cholera disturb the intestinal balance and can cause severe diarrhea and dehydration. The good news is that cholera is preventable.
• Gastroenteritis: In some instances the food and water we consume may be contaminated and lead to gastroenteritis—a condition that causes irritation and inflammation of the stomach and intestines, resulting in acute diarrhea and severe dehydration—which may be fatal.
