About

Peanuts are considered a functional food and regular consumption is associated with positive health effects. Protein is the second most common nutrient in peanuts after fat. The protein digestibility of peanuts is similar to that of animal protein, and the limiting amino acids in peanuts vary based on the study and are suggested to be lysine, methionine, or threonine. Defining the reduced responsiveness of various dietary proteins to induce anabolism in older adults is critical for preventing and attenuating physical and cognitive health decline.

Full description

The study will be conducted in healthy, non-frail older adults, stratified into different age categories. A sip feeding model will be used as it is a good model to establish the anabolic capacity of meals.Our research objective is to examine whether differences exist in the anabolic response and bioavailability of amino acids coming from peanut-based protein as compared to animal-based protein in older adults at risk for (pre-)frailty, known to contribute to poor muscle and brain health. The study will take place at the research facility of the Center for Translational Research on Aging and Longevity (CTRAL), Texas A&M University located in the Human Clinical Research Building ) affiliated with Texas A&M University. The study involves 1 screening visit of approx. 3 hours, and 4 study days. Some study procedures (e.g., body composition, skeletal muscle function, questionnaires) may be skipped if completed within the past 3 months at CTRAL. All data will be recorded in Case Report Form and stored in the Texas A&M REDCap System. Subjects will be asked to arrive in the fasted state on all study days. Fasting prior to screening is not required. On the screening day, body weight, height, and body composition by Dual-energy X-ray absorptiometry (DXA) will be measured. In addition, The Six-Minute Walk Test (6MWT) and skeletal muscle function tests will be assessed at the end of each screening visit. Each study visit will begin with vital signs. Before administration of the feeding or the tracer solution, baseline blood will be collected for measurement of the natural enrichment of metabolites. After the baseline sample is collected, feeding will begin and will be followed by tracers of several compounds that may be administered by IV pulse. Participants will receive the liquid nutritional supplement as sip feeds every 20 minutes for 5 hours. The liquid nutrition supplements will contain 45g of peanut protein (plant based). Comparison of results from meals taken while enrolled in NCTNCT06628349 will be performed. Participants will have the option of adding sugar free (SF) vanilla syrup, SF caramel syrup, or SF chocolate syrup to their meals.
