Unit 2- Nutrition & Physical Activity Flashcards
Define Nutrient
a compound that provides a needed function in the body.
Define Macronutrients
The nutrients the body needs in larger amounts.
Define Micronutrients
The nutrients the body needs in smaller amounts.
List the Macronutrients
Fats-Carbohydates-Protein FCP
List the Micronutrients
Vitamins-Minerals-Water VMW
How many calories per gram are needed for each Macronutrient?
9 Calories per gram for Fats-4 Calories per gram for Carbohydrates-4 Calories per gram for Protein 944 FCP
What percentage of your caloric intake needs to be dedicated for each macronutrient?
Fats: 20-35% Carbohydrates: 40-65% Protein: 10-35%
Define Calories
Amount of energy required to heat 1L of water at 1 degrees Celsius.
What are the 5 major uses of fat in the body?
Insulation-Buoyancy- Absorption of Fat Soluble Vitamins-Protection of Organs- Energy IBAPE
What are the types of Fat and where can they be found?
Saturated-Unsaturated-Hydrogenated Saturated Fats are typically found in animal sources, solid at room temperature
Unsaturated Fats are typically found in plant sources and they are liquid at room temperature.
Hydrogenated Fats are Trans Fats. SUH
What is the function of Protein in the body?
They’re used to build the solid structures of the body, bone, hair, nails, connective tissues, enzymes, red blood cells, and some hormones.
Protein intake should be a direct reflection of the _____ done by the body.
Amount of Work.
What are the Protein types and where are they found?
Complete-Incomplete CI
The sources of complete proteins are typically animal products.
The sources of incomplete proteins are typically plant products.
What does AMDR stand for?
Acceptable Macronutrient Distribution Range
_____ are the preferred form of energy in the body?
Carbohydrates
List the types of Carbohydrates and explain them.
Simple-Complex SC
Simple Carbs: one sugar, break down on the tongue, digest quickly, spike blood sugar.
Complex Carbs: more than one sugar, typically broken down in the stomach, regulate blood sugar due to slow absorption rates.
Explain the Enrichment of Carbohydrates
The enrichment process eliminates the outer coating of the wheat germ, essentially eliminating fiber, thus allowing this wheat to be broken down in the mouth and will cause spikes in blood sugar. This type of carbohydrate is very useful when needing an energy spike.
Define Vitamins
Vitamins are the organic micronutrients needed by the body.
What are the types of Vitamins and what Vitamins fall under each category?
Fat Soluble-Water Soluble FW
Fat Soluble: A,D,E,K FADEK
Water Soluble: C, B Complexes WCB
Where are Vitamins typically found?
Fruits, Vegetables, and fortified grains.
Making sure you are getting a variety of _____ and _____ ensures vitamin balance.
Fruits and Vegetables.
If not eating any veggies or fruits, or eating just one type, a _____ may be needed to ensure vitamin levels.
Multi-Vitamin
Define Minerals.
The inorganic source of nutrients for the body.
What are the types of minerals and what minerals fall under each category?
Major-Trace MT
Major: Calcium, Phosphorus, Magnesium, Sodium, Potassium, and Chloride. MCPMSPC
Trace: Copper, Fluoride, Iodide, Selenium, and Zinc. TCFISZ
To ensure vitamin and mineral intake is sufficient, make sure you are eating a balanced diet rich in _____, _____, and _____.
Vegetables, Fruits, and Unrefined Carbs. VFU
What are the functions of Vitamins and Minerals?
Boost the immune system, support normal growth and development, and help cells and organs do their job. IDO
Carrots are full of substances called _____ that your body converts into _____, which helps prevent eye problems.
Carotenoids, Vitamin A
What function does water have in the body?
Food absorption, joint lubrication, blood flow, and most chemical reactions in the body. FJBC
The body is composed of about ______ water.
60%
Water balance should cause _____ clear urinations a day.
5
List some electrolytes.
Sodium-Potassium
Explain everything about Sodium.
Sodium is found in most of our common food choices. Very prevalent in fast foods, boxed foods and frozen, pre-made foods.
Sodium is lost in sweat and needs to be replenished after exercise.
Explain everything about Potassium.
Potassium is found in large amounts in oranges, sweet potatoes, and bananas.
Potassium is also lost during exercise and needs to be replenished.
Diets high in high _____ can cause high _____. One way to lower sodium levels in the body is to increase the intake of _____.
Sodium-Blood Pressure-Potassium.
Define Fiber.
Fiber is an essential part of nutritional intake that is known to lower the risk of heart disease and cancer.
List the types of Fiber and explain them.
Soluble-Insoluble
Soluble: This type of fiber binds to cholesterol containing items and helps remove them from the body. Known to lower the risk for heart disease.
Insoluble: Binds to water in the intestines and softens stool.
What is the typical fiber intake for men and women?
Men: 30-40g
Women: 20-35g
Define Carbohydrates.
The word carbohydrate literally means “hydrated carbon,” or carbon with water. Can be either simple or complex.
Define Fats
Lipids consist of fatty acids, triglycerides, phospholipids, and steroids (cholesterol). Can be either saturated or unsaturated. FTPS
Define Proteins.
Protein is another macronutrient that, like carbohydrates, consists of small repeating units. But instead of sugars, proteins are made up of amino acids, Can be either complete or incomplete.
Define Soluble Fiber
Fiber that is found to lower cholesterol levels.
Define Insoluble Fiber
Fiber that binds to water and allows for soft fecal matter.
How is a food’s kilocalories determined?
It’s determined by putting the food into a bomb calorimeter and determining the energy output.
Define % Daily Value
Shows how much a nutrient in a serving of the food contributes to a total daily diet. It can help you determine if a serving of the food is high or low in an individual nutrient and to compare food products.
How much %DV is considered high/low?
5% or less DV of a nutrient per serving is considered low and 20% or more DV of a nutrient per serving is considered high.
According to MyPlate, what are the food groups?
Fruits, Grains, Vegetables, Protein, Dairy FGVPD
Define Body Composition
