Metabolic Availability of Methionine From Chickpeas in Adult Men
A study testing Dietary Intakes in people with Healthy, run by The Hospital for Sick Children at 1 site in Canada.
Trial summary
The research study is being done so we can determine the quality of the protein present in Canadian chickpeas. 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).

About this study
Official title: Study Title: Application of the Indicator Amino Acid Oxidation Technique for the Determination of Metabolic Availability of Methionine From Canadian Lentils, in Healthy Young Adult Men
The research study is being done so we can determine the quality of the protein present in Canadian chickpeas. 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…Chickpeas as a food source contain low amounts of the essential amino acid methionine which makes its protein incomplete. The amino acids in chickpeas are also affected by cooking. Our objective is to determine the amount of methionine in chickpeas that the body can use. We will test chickpeas by studying them after cooking them, on their own and by combining the chickpeas with rice 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 chickpeas 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 chickpeas are important alternatives shown to "enhance ecosystem resilience, and improve human health.
Read the detailed description
If you agree to take part in this study, you will receive 3 different amounts of chickpeas which will contain different amounts of the essential amino acid methionine as well as 3 different amount of chickpeas complemented with rice. The chickpeas will be cooked on its own or served with the rice. The quality of the protein in the chickpeas 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 chickpeas 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.

You could be expected to participate in up to 10 different sets of experiments which will take 11 weeks to 6 months. Each set of experiment consists of a 3 day period. During the first 2 days (Adaptation Days) you will be expected to consume 4 meals per day consisting of a protein liquid drink and protein freecookies and/or chickpeas with or without rice, which will be provided by the investigators Receives: Other: Dietary Intakes |

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03339154, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Nov 2018.
