Exam 4 Flashcards
Albumin
keeps fluid from leaking out of vessels into other tissues, synthesized in the liver
Fat is essential for
brain and nerve function
types of macronutrients
carbs, lipids, and protein
types of micronutrients
vitamins and minerals
types of fatty acids
saturated and unsaturated- saturated
LDL is
transports cholesterol to the body’s cells, “bad cholesterol”, saturated fats increase LDLs
HDL is
High Density Lipoproteins remove cholesterol from the bloodstream and return it o the liver where it is used to produce bile. “good cholesterol”
What is nutrition?
study of food and how it affects the body
What is metabolism?
process by which the body converts food to energy
What is the estimated average requirement?
amount of a nutrient that is estimated to meet the requirement of half of all healthy individuals in a certain age and gender group
What are the parts of a food label?
serving size, servings per container, calories, and percentages of nutrients based on daily value
What is the daily calorie amount that food labels are based on?
2000
Types of carbohydrates (CHOs)
simple carbs(sugars), complex carbs
What is a simple sugar? Example
corn syrup, honey, milk, table sugar, fruits
What is a complex carb? Ex
vegetables, bread, pasta, grains
What do carbs do?
give the body energy, enhance insulin production, increase satiety (fullness and satisfaction), improve absorption of sodium and excretion of calcium
What are proteins made out of?
amino acids
What are the kcals for carbs, proteins, and fats?
4-carbs, 4-proteins, 9-fats
What do proteins do for the body?
tissue building, metabolism, help with immune system function, fluid balance, acid-base balance, secondary to carbs for energy source
What do lipids (fats) do for the body?
supply the body with essential fatty acids and aid in the absorption of fat soluble vitamins, energy source when engaging in sustained light activity, give food flavor, body fat is insulating, cholesterol is a component of every cell in the body-it lends suppleness and support
What are the fat soluble vitamins?
(remember a fat dek of cards) Vitamin A, D, E, and K
Which type of vitamin is stored in the body?
Fat soluble
Which types of vitamins need to be eaten daily as they are excreted out of the body in urine?
Water soluble
What are the water soluble vitamins?
thiamin, riboflavin, niacin, b6, pantothenic acid, folic acid, b12, and C
What does Vitamin A do in the body?
maintains healthy skin and vision. growth of skeletal and soft tissues, reproduction
Importance of Vitamin K
synthesis of clotting factors and bone development
Importance of Vitamin D
regulates calcium and rate of deposit and reabsorption of calcium in bone
Where is vitamin K made in the body?
Bacteria in the intestines synthesize vitamin K
Why do Infants need a vitamin K shot after birth?
Bacteria in the gut helps form vitamin K. Infants do not yet have this bacteria and vitamin K helps with clotting factors
What is vitamin K an antidote for?
Coumadin-blood thinner
What is the test needed for Coumadin or Warfarin?
I&R
Foods that help with vitamin K
green leafy veg, liver
Foods that help with Iron
meats, eggs, beans, fortified cereal. If eaten with source of vitamin c, absorption is increased
What helps the body absorb iron?
Vitamin C-educate pt to take supplement or with orange/juice
Importance of Iron
Hemoglobin production (RBCs), metabolism of glucose, antibody production, drug detoxification
Importance of Vitamin C
collagen synthesis, cementing substance for capillary walls, antioxidant, iron absorption, and immune function
Importance of Vitamin B12
metabolic reactions, maintains myelin sheath, hemoglobin synthesis
What does vitamin D help with the absorption of?
Calcium
Importance of calcium
Helps with bone strength
What time of a woman’s life does she need to begin a calcium supplement or upping calcium intake and why?
Menopause. Lower estrogen can cause bone weakness leading to osteoporosis or brittle bones
Why do pregnant women or women of child bearing age need to take a folate supplement?
Helps to prevent neural tube defects
What are the macrominerals?
Minerals body need in amounts of 100mg/daily, calcium, Magnesium, phosphorus, potassium, sodium
What are the trace minerals?
Essential in much lower concentration, copper, fluoride, iodine, iron, zinc
Why is water essential to the body?
Makes up about half of body weight- solvent for body’s chemical processes, transport oxygen, nutrients, and metabolic wastes, fills in spaces in the body tissues, temperature regulation, lubricant for joins and abdominal cavities, catalyst for many reactions
What is the necessary amount of water daily?
8-10 8 oz glasses of water daily
Why do men have more water content in their body?
Higher muscle mass
Iodine’s importance
synthesis of thyroid hormone (thyroxine), can be obtained easily through iodized table salt
What is basal metabolic rate?
measure of energy used by the body when it is at rest- required for vital organs to function
How do you measure bmr in a woman?
0.9 kcal multiplied by weight in kg
How do you measure bmr in a man?
1 kcal multiplied by body weight in kg
What factors affect a bmr?
body composition (more muscle=greater BMR), growth periods, body temperature, environmental temperature, disease processes, prolonged physical exertion
