Cards

Term
Hard Water
Definition
high in calcium and magnesium
Term
Soft Water
Definition
High in sodium, dissolved cadmium and lead from pipes
Term
Most Abundant Mineral in the body
Definition
Calcium
Term
Phosphorous
Definition
a mineral that that maintains acid-base balance of cellular fluids, is part of DNA & RNA, helps metabolize nutrients and assists enzymes to extract energy from nutrients
Term
Magnesium
Definition
a mineral that is present in very small amounts in the body but is important in that it works with calcium to ensure proper muscle function. Calcium helps muscles contract, this mineral helps them relax. 
Term
Sodium
Definition
this mineral is important in maintaining the body's fluid and electrolyte balance. This is the chief ion that maintains fluid OUTSIDE the cell. Too much can lead to hypertension. 
Term
The DASH Diet
Definition
intended to lower blood pressure. Reduces salt & sodium, increases intake of fruits & veggies, nuts and poultry and low-fat dairy. "Dietary Approaches to Stop ------------"
Term
Potassium
Definition
this mineral is the principle positively charged ion INSIDE the body's cells. Maintains fluid & electrolyte balance, maintains heartbeat. Found in bananas, oranges, spinach and cantaloupe. 
Term
Chloride
Definition
this mineral is the body's major negative ion. It is responsible for stomach acidity and therefore aids in protein digestion. The major food source of this is table salt. 
Term
Sulphate
Definition
this mineral is the oxidized form of sulphur and helps synthesize sulphur-containing body compounds
Term
Iodine
Definition
a trace mineral that is a part of throxine which helps metabolize. Deficiency can lead to a goiter, sluggish behavior and weight gain . Found naturally in seafood but is added to milk and bakery products
Term
Cretinism
Definition
irreversible mental & physical retardation of a newborn, caused by an iodine deficiency during pregnancy. 
Term
Iron
Definition
this trace mineral is found, in tiny amounts, in every cell in the body. Stored in the liver. Without this mineral, hemoglobin can't carry oxygen from the lungs to tissues throughout the body. Found in meat sources
Term
Anemia
Definition
Low blood hemoglobin, leading to too large or too small, immature blood cells. "too little blood". Caused by iron deficiency
Term
Zinc
Definition
a trace mineral which works with proteins in every organ, makes part of the cells genetic material, and makes heme in hemoglobin. Deficiencies in children cause growth & retardation. 
Term
Selenium
Definition
a trace mineral that protects against oxidative destruction. Deficiency increases the likelihood of heart disease. Widely found in unprocessed foods. 
Term
Fluoride
Definition
a trace mineral that is not essential to life but useful in that it prevents dental caries by promoting remineralization of enamel.
Term
Chromium
Definition
a trace mineral that works closely to regulate and release insulin from glucose. Therefore, a deficiency leads to impaired insulin and potentially high blood pressure. 
Term
Copper
Definition
a trace mineral that is needed to form collagen and hemoglobin. Also depended on by many enzymes because of its ability to handle oxygen. 
Term
Overweight
Definition
Having a BMI of 25 or over
Term
Underweight
Definition
Having a BMI of less than 18.5
Term
Visceral Fat
Definition
fat which collects near the abdomen and increases the risk of diabetes, heart disease and hypertension because it is readily released into the blood stream, which raises cholesterol
Term
Adipose tissue
Definition
fat tissue; performs several functions such as the synthesis and secretion of leptin
Term
Leptin
Definition
a hormone that regulates and suppresses appetite. Produced in fat cells. Believed to maintain body composition (the more leptin, the less you eat=thin)
Term
Daily Energy Balance
Definition
Change in energy stores= energy in-energy out
Term
1 pound
Definition
3500 calories approx
Term
Basal Metabolism
Definition
the rate at which the body uses energy while at rest, to keep the vital body functions going (ie breathing, circulation, temperature maintenance etc). Controlled by thyroxine. 
Term
Ghrelin
Definition
the hormone that signals the hypothalamus to stimulate eating. 
Term
Satiation
Definition
the feeling of fullness that stops you from continuing to eat. 
Term
Satiety
Definition
the feeling of fullness that lasts AFTER you've stopped eating. Determines the amount of time that passes between meals
Term
Energy Density
Definition
measure of an energy provided by a food compared to its weight... calories per gram. The lower the energy density, the better. 
Term
Cathartic
Definition
a strong laxative
Term
Emetic
Definition
something that causes vomiting
Term
Female Athlete Triad
Definition
disordered eating, amenorrhea and osteoporosis
Term
Amenorrhea
Definition
When menstruation no longer occurs. 
Term
Hypertrophy
Definition
muscles gaining strength and size in response to overload (extra physical demands)
Term
Atrophy
Definition
the weakening and diminishing of muscles due to lack of use
Term
VO2max
Definition
The maximum rate of oxygen consumption of an individual. Measured at sea level. 
Term
Anaerobic Use Of Glucose
Definition
Glycogen is broken down quickly. Heart and lungs are not required to work for an extended period of time... ex, a sprint. 
Term
Aerobic Use Of Glycogen
Definition
Glycogen is used slowly, because energy is extracted from both glycogen and fat stores. Ex, a light jog
Term
Lactic Acid
Definition
this is produced during intense workouts due to the breakdown of glucose. It travels to the liver and is converted back to glucose which provides additional fuel. 
Term
Carbohydrate Loading
Definition
Moderate Exercise followed by a high-carb diet. this enables muscles to temporarily be able to store more glycogen than normal. Athletes sometimes use this technique before a big race.
Term
Sports Anemia
Definition
low blood hemoglobin during the early stages of training. This problem goes away on its own and does not require iron supplements. 
Term
Hyponatremia
Definition
low sodium concentration in the blood
Term
Atherosclerosis
Definition
most common cardiovascular disease. Plaques harden the arteries. 
Term
Myocardial Infarction 
Definition
the vessels that feed the heart become closed off by an embolism or a thrombus, resulting in tissue death (a heart attack) 
Term
