severe wasting, loss of fat and muscle tissue
Term
Kwashiorkor
Definition
loss of fat and muscle, but edema present, skin and hair color changes, fatty liver and impaired renal function
Term
Saturated Fatty Acids
Definition
-no double bonds, associated with increased risk of cardiovascular disease
Term
Monounsaturated Fatty Acids
Definition
-single double bonds, not associated with cardiovascular disease risk
Term
Poly-unsaturated Fatty Acids
Definition
-multiple double bonds associated with lower LDL levels
Term
Essential Fatty Acids and signs of EFA deficiency
Definition
-Linoleic acid:: an omega-6 fatty acid
-Linolenic acid:: an omega-3 fatty acid
-EFA deficiency::infertility, scaly dermititis
Term
Structure, function, and health consequences of trans fatty acids
Definition
-manufacturing change in double bond from cis configuration to trans
-increases viscosity of vegetable oils and stability of baked goods
-Found to increases LDL and lower HDL
Term
Mechanisms by which dietary fiber may impact plasma cholesterol levels
Definition
a. sequester bile in get, decreasing reabsorption
b. slow carbohydrate absorption and subsequent rise in plasma insulin levels, thereby slowing cholesterol synthesis
c. stimulate short-chain fatty acid synthesis thereby inhibiting cholesterol synthesis
