Metabolic Availability of Methionine From Mung Beans in Healthy Young Adult Men

2018-09-24 06:23:25 | BioPortfolio

Summary

The research study is being done so we can determine the quality of the protein present in Mung beans. Amino acids are the building blocks of protein and protein quality is determined by the amount of amino acids present and by their bioavailability (their absorption and use by the body). Some amino acids are essential which means they must be obtained from the diet. If any one of the essential amino acids is missing in the diet, the body cannot make proteins that are used to repair tissue build bone, teeth, etc… Mung beans as a food source contain low amounts of the essential amino acid methionine which makes its protein incomplete. The amino acids in Mung beans are also affected by cooking. Our objective is to determine the amount of methionine in Mung beans that the body can use. We will test Mung beans by studying them after cooking them in a stew, on their own and by combining the Mung bean stew with rice or wheat in a mixed meal to make a more complete protein.

This research is being done in order to bridge the gap between knowledge of protein requirement and the amount of food needed to meet that requirement. Results from this study will be important for recommendations guiding food choices of Mung bean as a major protein source in the diet.

Previously the quality of dietary protein for human consumption was studied in animals. This study is being done in humans because studies in animals are not directly applicable to humans. Excessive animal protein consumption is also linked to cardiovascular disease. Plant protein sources like Mung beans are important alternatives shown to "enhance ecosystem resilience, and improve human health.

Description

If you agree to take part in this study, you will receive 3 different amounts of Mung beans which will contain different amounts of the essential amino acid methionine as well as 3 different amount of Mung beans complemented with rice or wheat. The Mung beans will be cooked in a stew served on its own or served with the rice or wheat. The quality of the protein in the Mung beans will be compared to the quality of a reference protein (egg protein) by giving you 4 reference diets containing amino acids make up like the amino acids in egg protein. The amount of Mung beans you receive will be provided in a random order.

Breath samples will be collected after the 4th meal in 15 min intervals for 1 hour. Breath collection will resume again two and a half hours after the 5th meal every 15 minutes until 30 minutes after the last meal. A total of 52 breath samples will be collected during each of the 3rd study day.

Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.

Iron or iron compounds used in foods or as food. Dietary iron is important in oxygen transport and the synthesis of the iron-porphyrin proteins hemoglobin, myoglobin, cytochromes, and cytochrome oxidase. Insufficient amounts of dietary iron can lead to iron-deficiency anemia.

Phosphorus used in foods or obtained from food. This element is a major intracellular component which plays an important role in many biochemical pathways relating to normal physiological functions. High concentrations of dietary phosphorus can cause nephrocalcinosis which is associated with impaired kidney function. Low concentrations of dietary phosphorus cause an increase in calcitriol in the blood and osteoporosis.
