Soluble dietary fiber has the following properties:
• Delays gastric emptying
• Slows intestinal transit time
• Slows glucose absorption
• Is fermented in the colon into short-chain fatty acids that may inhibit liver cholesterol
synthesis and help clear LDL cholesterol
On the other hand, insoluble dietary fiber—cellulose, lignin, and many hemicelluloses—
found in vegetables, wheat, and most other grains does not have these lipid-lowering
effects. Thus an increased use of soluble fiber food sources, especially oat bran and
legumes, would have beneficial effects.
Omega 3 fatty acids
Found mostly in seafood and marine oils, also have protective functions. They can do the
• Change pattern of plasma fatty acids to alter platelet activity and reduce platelet
aggregation that causes blood clotting, thus lowering the risk of coronary thrombosis
• Decrease the synthesis of VLDL
• Increase anti-inflammatory effects
It would seem, then, factors in foods such as oats, dried beans, and fatty fish would
provide valuable lipid-lowering additions to our diets.
Chronic Obstructive Pulmonary Disease (COPD)
Increased energy requirements
Progressive CHF contributes to lung disease and risk of respiratory failure.
Malnutrition is common with the debilitating condition of chronic obstructive
pulmonary disease (COPD). This term describes a group of disorders in which
airflow in the lungs is limited and respiratory failure develops. Chronic bronchitis
and emphysema are two main interrelated COPD conditions. Malnutrition usually
accompanies COPD, and its presence increases illness and death rates associated
with the disease process. Anorexia and significant weight loss reflect a growing
inability to maintain adequate nutritional status, which in turn severely
compromises pulmonary function.
Progression of the disease process, with its increasing shortness of breath,
prevents the person from living a normal life, and prognosis is poor. Eventually, in
progressive respiratory failure, the patient becomes dependent on a mechanical
respirator and controlled oxygen supply. A poor prognosis is associated with a
compromised nutritional status in these patients.
