by   Raymond Kurzweil

Adrenaline: also known as epinephrine. A hormone secreted by the adrenal gland during stressful situations. Adrenaline stimulates the heart and nervous system, preparing the body for action. Muscles contract, blood pressure and heart beat increase, and the immune and digestive systems shutdown.

Adult-onset diabetes: see Type II diabetes mellitus.

Aerobic exercise: exercise that lasts more than ninety seconds, works large muscle groups, and provides oxygen to the muscles. Examples: brisk walking, running, swimming.

Aflatoxin: a carcinogen produced by a mold that grows on potatoes, corn, and peanuts.

Anaerobic exercise: high-intensity exercise that does not supply oxygen to the muscles or lasts for less than ninety seconds. Examples: weight training, sprinting, calisthenics.

Aneurysm: a bulging area of a weakened blood vessel, usually an artery. An aneurysm often develops as a result of atherosclerosis.

Angina: a condition marked by chest pains or pressure due to decreased blood supply to the heart Angina is often a symptom of advanced atherosclerosis.

Arrhythmia: irregularity or loss of rhythm in the heartbeat.

Artery: a vessel that carries blood from the heart to tissues throughout the body.

Arthritis: inflammation of the joints and other connective tissues.

Atherosclerosis: a progressive disease in which plaque forms in the inner lining of arteries, causing narrowing or blockage of artery walls.

Balloon angioplasty: a treatment to widen a blood vessel severely narrowed by plaque. An inflatable device is inserted past the narrowed path of the blood vessel and is inflated, forcing the narrowed vessel open.

Barbiturate: a group of drugs, used as sedatives and tranquilizers, that depress the central nervous system and respiration, decrease blood pressure, and affect heart rate.

Benzodiazepine: a group of tranquilizers and sleeping pills that temporarily reduce anxiety but can produce long-term dependency and depression. Examples of tranquilizers: Valium (diazepam), Librium (chlordiazepoxide), and Tranxene (clorazepate). Examples of sleeping pills: Dalmane (flurazepam) and Halcion (triazolam).

Among other dramatic results, the study found that the rate of heart disease in the rural counties of China is 155 times lower than in the United States. In those Chinese counties in which people eat higher levels of fat and cholesterol, rates of heart disease, cancer, and other diseases are substantially higher (as compared to the low-fat counties). The study also found links between salt consumption and hypertension.

Cholesterol: (1) serum or blood cholesterol: a fat-soluble waxy substance (specifically the crystalline steroid alcohol C27H45OH) in the blood that is often deposited in artery walls. Cholesterol is used to produce bile acids and certain hormones and to construct cell membranes. Excess blood cholesterol is a result of a high-fat, high cholesterol diet or of genetic factors. (2) dietary cholesterol: a naturally occurring waxy substance (C27H45OH, see above) found in animal fats and oils.

Cirrhosis: extensive scarring and destruction of the cells in the liver, often due to excessive alcohol intake.

Fat: (1) body fat: a tissue that provides insulation and a reserve supply of energy. Body fat also aids in the construction of cell membranes and the regulation of menstrual cycles. (2) dietary fat one of six nutrients needed to sustain human life. Dietary fats help transport certain vitamins through the digestive system. Dietary fat is found in meats, certain vegetables, and dairy products. An excessive level of dietary fat is regarded as a primary factor in the development of coronary heart and artery disease, cancer, and other illnesses.

Fight-or-flight response: in certain animals, a reaction necessary for survival. When confronted with danger, the animal prepares to either fight or flee. As a result of this evolutionary heritage, the fight-or-flight response in humans today is a physiological reaction to stressful situations.

Food craving: an urge to eat certain foods, especially foods with high salt, sugar, or fat content. Often, cravings for sugar are a result of a diet high in both fat and sugar.

Framingham Study: A renowned study that has spawned many journal articles over the years. The Framingham Study has been tracing approximately five thousand individuals(in Framingham, Massachusetts) since 1948 to determine the risk factors for coronary heart disease and has yielded landmark evidence establishing the link between dietary fat consumption, lipid cholesterol levels, high blood pressure, smoking, obesity, and diabetes and the risk of coronary heart disease.

The two types of miners are macrominerals (such as sodium and potassium), needed in large amounts, and trace minerals (such as zinc), needed in small amounts. Minerals are found in meat and dairy products, vegetables, fruits, grains, seeds, seafood, and salt.

Monounsaturated fat: a form of fat found in olive and peanut oil, peanuts, almonds, and avocados. Monounsaturated fat does not raise LDL ("bad" cholesterol) levels as much as saturated fat and does not depress HDL ("good" cholesterol) levels as much as polyunsaturated fat.

MR FIT Study: the Multiple Risk Factor Intervention trial followed 15,000 men at high risk for heart disease for 7 years. The study showed that the conventional medical recommendations (i.e., reducing fat to 30 percent of calories, reducing cholesterol intake to 300 mg per day) reduced the number of coronary deaths and events by more than 30 percent.

Polyunsaturated fat: a form of fat in food, usually a major constituent of oils from certain vegetables and seeds. While polyunsaturated fats appear to raise LDL ("bad" cholesterol) levels less than saturated fat, they appear to depress HDL ("good" cholesterol) levels more than saturated fat and have been implicated as a promoter of cancer growth.

Potassium: a mineral essential for muscle function, balance of body fluids, and transmission of nerve impulses. Potassium is found in cereals, dried peas and beans, fresh vegetables and fruits, certain seeds, fresh fish, and certain meats.

Protein: one of six types of nutrients needed to sustain human life. Protein is used to build muscles, connective tissues, and cell walls. It is found in meat and dairy products; legumes such as kidney and lima beans; rice; and certain seeds, nuts, and vegetables.

Quantitative coronary angiography: a procedure that determines the degree of blockage in arteries. Radioactive dye is injected into the heart, and X rays are taken to locate blocked arteries.

Relaxation response: a physical state that is the opposite of the fight-or-flight response. The relaxation response results in reduced blood pressure and blood glucose levels, and lower breathing and heart rates.

Risk factor: any medical condition (such as high blood pressure) or life-style behavior (such as smoking) that indicates the increased risk of the development of a medical problem.

Saturated fat: a form of fat in meat, coconut and palm oils, and animal sources such as whole-milk dairy products. These fats raise blood cholesterol levels, particularly LDL ("bad" cholesterol) levels.

Secretion: the formation and release of a substance in the body.

Set-point theory: the theory that each person has an individual thermostat governing how much food they want to eat and how much fat they will store from food intake. According to this theory, obese individuals may have difficulty losing weight because their set-point increases their hunger for food and stores more fat from food eaten.

Seven Countries Study: a study by Ancel Keys of sixteen population groups in seven countries over a span of ten years. It was the first study to compare the epidemiology of heart disease in different countries and provided rich evidence that fat in the diet was the primary cause of heart disease.

Simple carbohydrates: Also known as sugars. Simple carbohydrates are found in "natural" foods, such as fruits and vegetables, and "refined" or "processed" foods, such as cookies, candy, and cakes. Simple carbohydrates provide calories but no other nutritional value.

Triglyceride: a type of lipid carried in the bloodstream that may subsequently be used for energy.

Tumor: a growth of tissue that is progressive and often uncontrolled.

Type A personality: a hardworking, ambitious, and aggressive personality traditionally thought to be at greater risk for heart disease than other personality types. Contemporary studies show that having a Type A personality is only a risk factor for heart disease in regard to certain Type A characteristics, including frequent anger, chronic hostility, or inherent cynicism.

Type B personality: an easygoing, accepting, and complacent personality.

Type I diabetes mellitus: formerly known as juvenile-onset diabetes; also called insulin-dependent diabetes mellitus. This form of diabetes usually develops in people under age 25. It is characterized by the inability of the pancreas to produce sufficient insulin.

Type II diabetes mellitus: formerly known as adult-onset diabetes; also known as non-insulin- dependent diabetes mellitus. This is the most common form of diabetes, in which the pancreas is able to produce insulin but the body is unable to use it effectively. This form of diabetes occurs most often in adults over age 40 and may be controlled by diet, exercise, and attainment of optimal weight.

Uric acid: a waste product in urine.

Very low density lipoprotein (VLDL): a lipoprotein, related to triglycerides, that is linked to atherosclerosis.

Vitamin: one of the six types of nutrients needed to sustain human life. Vitamins help form blood cells, hormones, and genetic material. Vitamins are found in meat and dairy products, vegetables, fruits, cereals, and grains.
