GLOSSARY
Allergen: A substance that is capable of producing an allergic response in the body.
Allergy: Hypersensitivity caused by exposure to a particular antigen (allergen), resulting in an increased reactivity to that antigen on subsequent exposure, sometimes with harmful immunologic consequences.
Alzheimer's Disease: A progressive disease of the middle-aged and elderly, characterized by loss of function and death of nerve cells in several areas of the brain, leading to loss of mental functions such as memory and learning. Alzheimer's disease is the most common cause of dementia.
Angina: Angina pectoris. Severe, restricting chest pain with sensations of suffocation caused by temporary reduction of oxygen to the heart muscle through narrowed diseased coronary arteries.
Calcium: The body's most abundant mineral. Its primary function is to help build and maintain bones and teeth. Calcium is also important to heart health, nerves, muscles and skin. Calcium helps control blood acid-alkaline balance, plays a role in cell division, muscle growth and iron utilization, activates certain enzymes, and helps transport nutrients through cell membranes. Calcium also forms a cellular cement called ground substance that helps hold cells and tissues together.
Cancer: Refers to the various types of malignant neoplasms that contain cells growing out of control and invading adjacent tissues, which may metastasize to distant tissues.
Chronic: Usually Chronic illness: Illness extending over a long period of time.
Chronic Renal Failure: (CRF) Irreversible, progressive impaired kidney function. The early stage, when the kidneys no longer function properly but do not yet require dialysis, is known as Chronic Renal Insufficiency (CRI). CRI can be difficult to diagnose, as symptoms are not usually apparent until kidney disease has progressed significantly. Common symptoms include a frequent need to urinate and swelling, as well as possible anemia, fatigue, weakness, headaches and loss of appetite. As the disease progresses, other symptoms such as nausea, vomiting, bad breath and itchy skin may develop as toxic metabolites, normally filtered out of the blood by the kidneys, build up to harmful levels. Over time (up to 10 or 20 years), CRF generally progresses from CRI to End-Stage Renal Disease (ESRD, also known as Kidney Failure). Patients with ESRD no longer have kidney function adequate to sustain life and require dialysis or kidney transplantation. Without proper treatment, ESRD is fatal.
Colon: The part of the large intestine that extends to the rectum. The colon takes the contents of the small intestine, moving them to the rectum by contracting.
Diarrhea: Excessive discharge of contents of bowel.
Diuretic: An agent increasing urine flow, causing the kidneys to excrete more than the usual amount of sodium, potassium and water.
Dyspepsia: Indigestion.
Electrolyte: An element or compound that, when melted or dissolved in water or other solvent, breaks up into ions and is able to carry an electric current.
Enzymes: Specific protein catalysts produced by the cells that are crucial in chemical reactions and in building up or synthesizing most compounds in the body. Each enzyme performs a specific function without itself being consumed. For example, the digestive enzyme amylase acts on carbohydrates in foods to break them down.
Glucose: A sugar that is the simplest form of carbohydrate. It is commonly referred to as blood sugar. The body breaks down carbohydrates in foods into glucose, which serves as the primary fuel for the muscles and the brain.
Gout: A disease characterized by an increased blood uric acid level and sudden onset of episodes of acute arthritis.
Hormones: Chemical substances secreted by a variety of body organs that are carried by the bloodstream and usually influence cells some distance from the source of production. Hormones signal certain enzymes to perform their functions and, in this way, regulate such body functions as blood sugar levels, insulin levels, the menstrual cycle, and growth. These can be prescription, over-the-counter, synthetic or natural agents. Examples include adrenal hormones such as corticosteroids and aldosterone; glucagon, growth hormone, insulin, testosterone, estrogens, progestins, progesterone, DHEA, melatonin, and thyroid hormones such as thyroxine and calcitonin.
Lymph: A clear fluid that flows through lymph vessels and is collected from the tissues throughout the body. Its function is to nourish tissue cells and return waste matter to the bloodstream. The lymph system eventually connects with and adds to venous circulation.
Lymphatic System: A network of vessels which collect fluid from the tissues of the body and return it to the blood. Lymphatic fluid (also called lymph) is rich in white blood cells that fight infection and an important part of the body's immune system.
Magnesium: An essential mineral. The chief function of magnesium is to activate certain enzymes, especially those related to carbohydrate metabolism. Another role is to maintain the electrical potential across nerve and muscle membranes. It is essential for proper heartbeat and nerve transmission. Magnesium controls many cellular functions. It is involved in protein formation, DNA production and function and in the storage and release of energy in ATP. Magnesium is closely related to calcium and phosphorus in body function. The average adult body contains approximately one ounce of magnesium. It is the fifth mineral in abundance within the body--behind calcium, phosphorus, potassium and sodium. Although about 70 percent of the body's magnesium is contained in the teeth and bones, its most important functions are carried out by the remainder which is present in the cells of the soft tissues and in the fluid surrounding those cells.
Metabolism: The chemical processes of living cells in which energy is produced in order to replace and repair tissues and maintain a healthy body. Responsible for the production of energy, biosynthesis of important substances, and degradation of various compounds.
Migraine: Not just a headache, but a disorder affecting the whole body, characterized by clearly defined attacks lasting from about 4 to 72 hours, separated by headache-free periods; progresses through five distinct phases. Prodrome: experienced by about 50% of migraineurs and starting up to 24 hours before the headache - changes in mood, sensory perception, food craving, excessive yawning, or speech or memory problems. Aura: experienced by about 15% and starting within an hour before the headache - disruption of vision (flashing lights, shimmering zigzag lines, blind spot) or sensation (numbness or 'pins and needles' around the lips or hand), or difficulty speaking. Headache: usually pulsating and occurring on one side of the head, it may occur on both sides of the head and alternate from side to side. Muscles in the neck and scalp may be tender; there may be nausea and the desire not to eat, move, see or hear. Resolution: the headache disappears and the body returns to normal. Resolution may occur over several hours during sleep or rest; an intense emotional experience or vomiting may also end the headache. Postdrome: After the headache stops, the sufferer feels drained, fatigued and tired. Muscles ache, emotions are volatile and thinking is slow.
Milligram: (mg): 1/1,000 of a gram by weight.
Mineral: Plays a vital role in regulating many body functions. They act as catalysts in nerve response, muscle contraction and the metabolism of nutrients in foods. They regulate electrolyte balance and hormonal production, and they strengthen skeletal structures.
Phosphorus: The second most abundant mineral in the body found in every living cell. It is involved in the proper functioning of both muscles and nerves. It is needed for metabolic processes of all cells, to activate many other nutrients, and to form energy-storage and energy-releasing compounds. The phosphorus content of the body is approximately one percent of total body weight. Phosphorus combines with fats to form phospholipids.
Potassium: A mineral that serves as an electrolyte and is involved in the balance of fluid within the body. Our bodies contain more than twice as much potassium as sodium (typically 9oz versus 4oz). About 98% of total body potassium is inside our cells. Potassium is the principal cation (positive ion) of the fluid within cells and is important in controlling the activity of the heart, muscles, nervous system and just about every cell in the body. Potassium regulates the water balance and acid-base balance in the blood and tissues. Evidence is showing that potassium is also involved in bone calcification. Potassium is a cofactor in many reactions, especially those involving energy production and muscle building.
Pound: 454 grams, or about half a kilogram.
Protein: Compounds composed of hydrogen, oxygen, and nitrogen present in the body and in foods that form complex combinations of amino acids. Protein is essential for life and is used for growth and repair. Foods that supply the body with protein include animal products, grains, legumes, and vegetables. Proteins from animal sources contain the essential amino acids. Proteins are changed to amino acids in the body.
Serum: The cell-free fluid of the bloodstream. It appears in a test tube after the blood clots and is often used in expressions relating to the levels of certain compounds in the blood stream.
Short-Term Memory: Also known as immediate memory or working memory, this is a phase of memory in which a limited amount of information may be held for several seconds to minutes. In general, up to 7 'chunks' of information are stored for about 20 seconds.
Sodium: An essential mineral that our bodies regulate and conserve. Excess sodium retention increases the fluid volume (edema) and low sodium leads to less fluid and relative dehydration. The adult body averages a total content of over 100 grams of sodium, of which a surprising one-third is in bone. A small amount of sodium does get into cell interiors, but this represents only about ten percent of the body content. The remaining 57 percent or so of the body sodium content is in the fluid immediately surrounding the cells, where it is the major cation (positive ion). The role of sodium in the extracellular fluid is maintaining osmotic equilibrium (the proper difference in ions dissolved in the fluids inside and outside the cell) and extracellular fluid volume. Sodium is also involved in nerve impulse transmission, muscle tone and nutrient transport. All of these functions are interrelated with potassium.
Ulcerative Colitis: (Colitis ulcerosa): Ulceration of the colon and rectum, usually long-term and characterized by rectal bleeding or blood in the stool, frequent urgent diarrhea/bowel movements each day, abdominal pain.
