what is the fate of excess intake of dietary protein
converted to individual amino acids
title: Protein (nutrient) text: severely restrict their intake of BCAAs in order to prevent mental retardation and death. The amino acids in question are leucine, isoleucine and valine. The condition gets its name from the distinctive sweet odor of affected infants' urine. Children of Amish, Mennonite, and Ashkenazi Jewish descent have a high prevalence of this disease compared to other populations. The U.S. and Canadian Dietary Reference Intake review for protein concluded that there was not sufficient evidence to establish a Tolerable upper intake level, i.e., an upper limit for how much protein can be safely consumed. Dietary protein is converted by the digestive title: Protein toxicity text: Protein toxicity Protein toxicity is the effect of the buildup of protein metabolic waste compounds due to insufficient kidney function. It can occur in people with pre-existing chronic kidney disease, or those who have lost kidney function due to age. Protein toxicity occurs when the body is unable to get rid of the potentially toxic wastes that are generated as a result of protein metabolism, it may be also caused by chronic kidney disease. Protein toxicity occurs when an individual with impaired kidney function consumes protein rich diet. Specifically proteins from animal sources that are rapidly absorbed into the blood title: Protein (nutrient) text: However, this recommendation is based on structural requirements but disregards use of protein for energy metabolism. This requirement is for a normal sedentary person. In the United States, average protein consumption is higher than the RDA. According to results of the National Health and Nutrition Examination Survey (NHANES 2013-2014), average protein consumption for women ages 20 and older was 69.8 grams and for men 98.3 grams/day. Several studies have concluded that active people and athletes may require elevated protein intake (compared to 0.8 g/kg) due to increase in muscle mass and sweat losses, as well as need for body repair title: Protein (nutrient) text: amino acids and their derivatives into which dietary protein is degraded is done by the gastrointestinal tract. The absorption rates of individual amino acids are highly dependent on the protein source; for example, the digestibilities of many amino acids in humans, the difference between soy and milk proteins and between individual milk proteins, beta-lactoglobulin and casein. For milk proteins, about 50% of the ingested protein is absorbed between the stomach and the jejunum and 90% is absorbed by the time the digested food reaches the ileum. Biological value (BV) is a measure of the proportion of absorbed protein from a title: Protein (nutrient) text: individual's energy and carbohydrate intake, and the presence of illness or injury. Physical activity and exertion as well as enhanced muscular mass increase the need for protein. Requirements are also greater during childhood for growth and development, during pregnancy, or when breastfeeding in order to nourish a baby or when the body needs to recover from malnutrition or trauma or after an operation. If not enough energy is taken in through diet, as in the process of starvation, the body will use protein from the muscle mass to meet its energy needs, leading to muscle wasting over time. If the
