Nutrition CH 1-2 Flashcards
Essential Nutrients are
Carbohydrates, Fiber, Proteins, Lipids, Vitamins, Minerals and electrolytes
DRI (Dietary Reference Intake )
Useful to understand food intake of large groups
EAR ( Estimated Average Requirement)
The amount of nutrients required to meet the basic requirement
AI ( Adequate Intake)
The amount of nutrients that most people in a group or population consume
Ul Upper limit-
The maximum of nutrient that a person can consume
AMDR (Acceptable Macronutrient Distribution Range)
The recommended percentage of intake for energy - yielding nutrients
Three things that give us energy
Carbohydrates, Proteins , Lipids
Carbohydrates
function
To provide energy of the body
Help cellular work
Help regulate protein and fat metabolism
Average amount to fuel the brain 130g/day for adults and children
Median carb intake is 305g/day for males
Median carb intake is 228g/day for women & children
AMDR for Carbs is 45%- 65% of cal
Body digest 95% of starch in 1-4hr after ingestion

Types of carbohydrates
Monosaccharides, Disaccharides, Polysaccharides
Monosaccharides
simple carbs, basic energy for cells
Sources ( corn syrup, fructose ,fruits, galactose found in milk)
Disaccharides-
simple carbs , energy aids calcium and phosphorus absorption
Sources ( sucrose= table sugar, lactose,
Polysaccharides
Complex carb energy storage starches, digestive aid fiber
Sources ( Starches = grains, legumes, fiber,= whole grain, fruits, vegetables)
Glycogen is stored CHO in liver and muscles, its is backup energy limit
Fiber
Is a categorized as a carbohydrate
Comes from plants its indigestible so it add bulk and stimulate peristalsis
Lower cholesterol & intestinal cancer
Keeps blood glucose levels stable
AI 25g/day female 38g/day for males
Fiber AI recommend
25g/day female 38g/day for males
Proteins
Provided by plants and animals
10 -35 % of daily calories
Tissue building, balance nitrogen and water, back up energy, support metabolic process & immune system
Two types of proteins
Complete proteins- from animal source and soy, has all nine essential amino acid
Incomplete proteins - generally from plant source, insufficient number of amino acid
Lipid
sources
Dark meats, Poultry skin, Dairy foods, Added oils
Lipids functions
Serves as a concentrated form of strode energy for the body and supply important nutrient needs
- protecting padding for organs, hormone production, insulation for body temperature, cell wall structural , covering nerve fibers, absorption for fat-soluble vitamins
Types of Lipids/ fats
- Triglycerides, phospholipids, sterols
Lipid % intake
20- 35% of daily calories 10% should be saturated fat
