do not dissolve in water
insoluble fibers
pectin in fruits like apples, pear, Oats and legumes
Decrease the rate of passage of materials and delay absorption of nutrients.
Soluble fiber
cellulose, lignin in leafy vegetables
Wheat and most grain products are
Good sources
Greater fecal bulk and increase in the rate of passage material; used to treat constipation

are found primarily in plants

CARBOHYDRATES are composed of the elements
C, H, O
Sources of Blood Glucose
Carbohydrates in the diet.
Liver Glycogen

soluble
are a type of lipid, a fatty substance that do not dissolve in water.
Fats
The building blocks of fats are called
fatty acids
Fatty Acids are classified as two types
Saturated
Unsaturated
Animal fats and tropical oils (like fatty portions of meat, butter, cheese, coconut oil and chocolate.)
High intake is associated with an increased risk of heart disease
Saturated
TRUE OR FALSE:
High intake of saturated fatty acids is associated with an increased risk of heart disease
TRUE
TRUE OR FALSE:
High intake of unsaturated fatty acids is associated with an increased risk of heart disease
FALSE
Vegetable fats (oils from plant origin like corn, olive, soya, canola, sunflower, safflower oils)
Associated with a reduced risk of heart disease
Unsaturated
TRUE OR FALSE:
Unsaturated fatty acids are Associated with a reduced risk of heart disease
TRUE
TRUE OR FALSE:
saturated fatty acids are Associated with a reduced risk of heart disease
FALSE
Fatty acids that the body needs, but is unable to make are called
essential fatty acids
Transport vitamins A, D, E, and K
FATS
essential fatty acid that is needed for growth and healthy skin
linoleic acid
Sources of linoleic acid
FATS
TRUE OR FALSE:
Excess cholesterol can lead to an increased risk of heart disease
TRUE
TRUE OR FALSE:
Excess cholesterol can lead to a decreased risk of heart disease
FALSE
examples are triglycerides
Simple Lipids
examples are phospholipids and lipoprotein
Compound Lipids
examples are fatty acids, glycerol and cholesterols
Derived Lipids
FAT Is a major component of _____________________________
cell membranes and myelin sheaths
adipose tissues or body fat maintains body temperature within vital range necessary for life
Thermal insulation
padding of adipose tissues around vital organs protects these organs from shock of injury.
Vital Organ Protection
are nutrients that help BUILD and MAINTAIN body cells and tissues.
Proteins
PROTEINS are made up of _________, THE BODY’S BUILDING BLOCK.
Amino acids
how many amino acids are necessary to create protein
20 Amino Acids (AA)
the only plant source of protein
Soy
help control water balance between the circulatory system and surrounding tissues.
Plasma proteins
TRUE OR FALSE:
In event of insufficient stores of carbohydrates and fats, protein can be converted into glucose and used for energy.
TRUE
TRUE OR FALSE:
In event of insufficient stores of carbohydrates and fats, amino acids can be converted into glucose and used for energy.
FALSE
Classification of Amino Acids
Essential Amino Acids
Non-Essential Amino Acids
indispensable to life and growth that THE BODY CANNOT MANUFACTURE, therefore must be supplied in the diet.
Essential Amino Acids
those that CAN BE SYNTHESIZED by the body.
Non-Essential Amino Acids
Classification of Protein According to Amino Acid Content
Complete
Incomplete
foods, which contain the entire essential AA in sufficient quantity and ratio to meet body’s needs.
Foods mostly of animal origin like eggs, milk, cheese and meat.
Complete
foods that are DEFECIENT in one or more of the essential AA.
Food mostly of plant origin like grains, legumes, nuts and seeds.
Incomplete
contain amounts of all nine essential amino acids.
COMPLETE PROTEINS
COMPLETE PROTEINS SOURCES
Fish, meat, poultry, eggs, milk, cheese, yogurt, and many soybean products.
lack one or more essential amino acids.
INCOMPLETE PROTEINS
INCOMPLETE PROTEINS SOURCES
