Antioxidants and Cancer

Antioxidants are compounds that have the potential to block the activity of other chemicals called free radicals. Free radicals are highly reactive chemicals that have the potential to harm cells. The damage done to the cells, particularly to the DNA of the cells, may play a role in the development of cancer and other diseases […] Read more

Nutrition in Pulmonary Stress

Nutrition in Acute Respiratory Distress Syndrome Pulmonary stress initiates a hypermetabolic, catabolic state. Even when overweight with acute respiratory distress syndrome (ARDS), weight loss should be prevented (AND, 2015a). A secondary goal of nutrition therapy is to prevent overfeeding, which leads to excessive CO2 production that further depresses respiratory function. Protein needs in ARDS and […] Read more

Determining Protein Needs_20.jpg

Determining Protein Needs

Protein needs are certainly heightened during critical illness, although no consensus or evidence exists to suggest the best method for determining protein needs. Protein needs are generally assumed to be in the 1.2 to 2.0 g/kg/day range for metabolically stressed patients (AND, 2015a). A.S.P.E.N. guidelines recommend protein needs in the 1.2 to 2.0 g/kg/day range […] Read more

Metabolic Stress and Critical Illness_5.jpg

Metabolic Stress and Critical Illness

Starvation and metabolic stress result in deviations from normal nutrient metabolism that alters individual nutrient needs. A chronically starved patient with mild metabolic stress experiences a reduction in resting metabolic rate of somewhere between 10 to 30 percent (Heimburger 2015). This reduction in resting metabolic rate is the body’s response to lowered energy intake that […] Read more
