Chapter 6 (Section B) Flashcards
Fats that cannot be produces in the body and must be consumer as part of a balanced diet
Essential fatty acids
Some of the specific functions of essential fatty acids include the following (7):
*Maintaining the structure and function of cellular and subcellular membranes *Serving as precursors for eicosanoids *Transferring oxygen from the lungs through the alveolar membrane *Maintaining proper brain and nervous system function Producing prostaglandins Healthy skin and hair *Healing wounds and the inflammatory response
A group of polyunsaturated fatty acids (2)
omega 6 and omega 3
Name three types of Omega 3 fatty acids
alpha-linoleic acid (ALA), elcosapentaenoic acid (ELA), docosahexaenoic acid (DHA)
On a macrolevel, what functions do omega 3’s have (4)?
support brain development, fight inflammation, improve bone density and reduce liver fat
Name a type of omega 6
linoleic acid
Ideal ratio of omega 3 to Omega 6; What is the western intake average?
4:1; 16:1
Roles of omega 6 fatty acids (2)
reduces adipose tissue deposits and improves immune function
What can excess/deficiency of linoleic acid lead to?
3/3
inflammation, headaches and lethargy/dermatitis and alopecia and developmental delays in children
Functions of ALA (alpha linolenic acid) (2)
important in growth and is the precursor for EPA and DHA
Good sources of essential fatty acids (5)
flax seeds, walnuts, chia, fatty fish, and poultry
the good cholesterol carrying LDL out of the bloodstream and to the liver where it is broken down and excreted
HDL
proinflammatory omega 6
arachidonic acid
A non essential omega 6 fatty acid derived from linoleic acid
gamma linoleic acid
Gamma linoleic acid is a precursor for which group of hormones? What functions are this hormone group responsible for (7)?
series 1 prostaglandins; preventing blood platelets from sticking together, controlling cholesterol formation, reducing inflammation, making insulin work better, improving nerve function, regulating calcium metabolism, and improving immune system functioning.
