Nutritional substrates, such as amino acids (AAs), are reprioritized from anabolism to support immune and stress responses, altering whole-body protein and glucose turnover, nitrogen balance, AA concentrations, hepatic protein synthesis, and glutathione (GSH) metabolism. Stress from inflammatory bowel disease, surgery, and critical illness share some metabolic characteristics. Therefore, a series of studies was designed to investigate: 1) protein and glucose metabolism under malnutrition superimposed with metabolic stress response; and 2) the nutritional and metabolic benefits of protein or AA supplementation. Methods: (Study 1) Colitis piglets (n =16) received a protein-deficient enteral diet for 10 days. They were then randomized to either control or supplementation with adequate protein or N-acetyl-cysteine (NAC). Protein and glutathione syntheses were measured by L-[ring-2H5]phenylalanine and [15N,1,2-13C2]glycine, respectively. (Study 2) Patients undergoing colorectal surgery with (n = 8) or without diabetes (n = 10) received parenteral AAs at 20% of their individually measured resting energy expenditure (REE) perioperatively for 72 hours. (Study 3) Patients undergoing cardiac surgery while on a hyperinsulinemic-normoglycemic clamp received parenteral AAs equivalent to either a high dose of 35% (n = 8) or a moderate dose of 20% (n = 8) of REE. (Study 4) Critically ill patients received either exclusive enteral nutrition (n=8) or enteral nutrition combined with parenteral AA supplementation to achieve a total protein intake of 1.75 (n = 9) or 2.5 g/(kg·d) (n = 9). Stable isotope tracers, such as D-[6,6-2H2]glucose, L-[1-13C]leucine and L-[ring-2H5]phenylalanine, were infused to determine glucose and protein kinetics in all three patient studies. Results: Protein repletion ameliorated plasma protein and tissue protein turnover and systemic GSH kinetics in piglets with colitis and pre-existing protein deficiency, whereas NAC supplementation alone increased cysteine concentrations, but it did not change GSH status. In patients with colorectal surgery, perioperative supplementation of AA alone improved protein balance in patients with diabetes similar to their non-diabetic counterparts. However, postoperative hyperglycemia was prevented only in patients with good glycemic control, but not in those with poor glycemic control before surgery. In patients receiving a hyperinsulinemic-normoglycemic clamp during cardiac surgery, high dose parenteral AAs prevented hypoaminoacidemia. In critically ill patients, high dose parenteral AA ameliorated plasma AA concentrations and improved protein balance compared to exclusive enteral nutrition without supplementation. The dietary protein response (net protein balance) was negatively correlated with clinical scores at ICU admission. Conclusion: Protein or AA supplementation in metabolic stress states improved protein and glucose metabolism. These studies provided insights into the limitations of current nutrition support strategies and a paradigm to improve nutritional interventions to develop optimal regimens. These may be applied in the design and conduct of larger clinical trials"--

Download or read book The Role of Protein and Amino Acids in Sustaining and Enhancing Performance written by Committee on Military Nutrition Research and published by National Academies Press. This book was released on 1999-09-29 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a commonly held belief that athletes, particularly body builders, have greater requirements for dietary protein than sedentary individuals. However, the evidence in support of this contention is controversial. This book is the latest in a series of publications designed to inform both civilian and military scientists and personnel about issues related to nutrition and military service. Among the many other stressors they experience, soldiers face unique nutritional demands during combat. Of particular concern is the role that dietary protein might play in controlling muscle mass and strength, response to injury and infection, and cognitive performance. The first part of the book contains the committee's summary of the workshop, responses to the Army's questions, conclusions, and recommendations. The remainder of the book contains papers contributed by speakers at the workshop on such topics as, the effects of aging and hormones on regulation of muscle mass and function, alterations in protein metabolism due to the stress of injury or infection, the role of individual amino acids, the components of proteins, as neurotransmitters, hormones, and modulators of various physiological processes, and the efficacy and safety considerations associated with dietary supplements aimed at enhancing performance.

Download or read book Nutrition and Aging written by Irwin H. Rosenberg and published by Karger Medical and Scientific Publishers. This book was released on 2002 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humanity is aging. In the last century, life expectancy has increased by as much as 25 years, the greatest increase in 5'000 years of history. As a consequence the elderly constitute today the fastest growing segment of the world's population. This new situation creates many social problems and challenges to health care which both the developed as well as the developing countries will have to cope with. The present publication shows that scientific progress has reached a level where nutritional interventions may play a decisive part in the prevention of degenerative conditions of age, improvement of quality of life and impact on health care burden and resources. Topics deal with such different aspects as the influence of prenatal and early infant nutrition on the future aged individual and effects of energetic restriction on longevity. Further contributions include studies on mitochondrial alterations, digestive problems, specific metabolic deviations mediated by insulin, bone degradation, structural changes, neuromuscular dysfunctions, mental state of the elderly as well as the response of the immune system to nutrient intake. Finally the book offers a review of requirements appropriate to meet the age-related public health challenges of the 21st century.

This book was released on 2009 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Which of the following will yield the fastest measurable change in performance and/or body composition? (A) changes in training. (B) changes in diet. (C) use of sports supplements. (D) they all work equally well. If you answered 'C,' go to the head of the class. That's right; the proper use of sports supplements can produce changes in minutes (e.g. caffeine), days (e.g. creatine) and weeks (e.g. beta-alanine). Yet we are bombarded by muddled thinking from the mainstream media telling us that 'creatine causes cramps,' 'high protein diets are bad for your kidneys,' 'supplements aren't needed as long as you eat a balanced diet' and other ideas that are void of data. Sports Nutrition & Performance Enhancing Supplements (eds. Abbie Smith-Ryan PhD CSCS*D CISSN and Jose Antonio PhD FNSCA FISSN. Linus Publications) is a focused resource that will give you the latest sports nutrition science, and eradicate the intellectually lazy positions held so dearly by the anti-supplement crowd."--Amazon.
