Today s nutrition facts are often tomorrows nutrition fallacies Unknown Diet refers to the foods we eat Nutrition refers to properly absorbing foods and staying healthy Well balanced diet is necessary for nutrition Malnutrition = decline in lean body mass with the potential for functional impairment Malnutrition synonymous with undernutrition JPEN J Parenter Enteral Nutr. 2009;33:710 716 3
Nutrition Risk Identified Compromised intake or loss of body mass Inflammation present? No / Yes No Yes Mild to Moderate Inflammatory Response Yes Marked Inflammatory Response Starvation Related Malnutrition (pure chronic starvation, anorexia nervosa) Chronic Disease Related Malnutrition (pancreatic cancer, rheumatoid arthritis, IBD) Acute Disease or Injury Related Malnutrition (major infection, burns, trauma, closed head injury) JPEN J Parenter Enteral Nutr. 2009;33:710 Characteristics Recommended for the Diagnosis of Adult Malnutrition Insufficient energy intake Weight loss Serum proteins such as albumin and pre albumin are not included! Loss of muscle mass Loss of subcutaneous fat Localized or generalized fluid accumulation that may sometimes mask weight loss Diminished functional status as measured by hand grip strength A minimum of 2 of the 6 characteristics is recommended for diagnosis of either severe or non severe malnutrition J Acad Nutr Diet 2012;36:275 83 4
Salivary Glands Saliva moistens / lubricates food. Amylase digests polysaccharides Esophagus Transports food Pancreas Hormones regulate glucose levels. Bicarbonate neutralize stomach acid. Trypsin and chymotrypsin digest proteins. Amylase digests polysaccharides. Lipase digests lipids Liver Metabolizes and synthesizes many biologic molecules. Stores vitamins and iron. Destroys old blood cells. Produces bile acids. Small Intestine Completes digestion Absorbs nutrients, most water Peptidases digests proteins Sucrases digest Sugars Amylase digests polysaccharides Stomach Stores and churns food. Pepsin digests protein. HCL activates enzymes, breaks up food, kills bacteria. Mucus protects stomach wall. Limited absorption Large Intestine Reabsorbs some water and ions. Forms, stores and expels feces Crohn s disease Ulcerative colitis Persistent inflammation of the gastrointestinal tract 5
IBD and Malnutrition Risk Malnutrition Why We Care: 30% of outpatient IBD patients with malnutrition IBD patients 5.57 times more likely to have malnutrition than those without IBD IBD patients often have low Vitamin D, B12, iron and more!
