Cottonseed oil (CSO) is found readily in the food supply, and the investigator's previous studies have demonstrated that incorporating CSO into the diet is sufficient to improve fasting and postprandial blood lipids and other markers of chronic disease risk in both healthy and at-risk populations. This study aims to examine the impact of intermittent CSO consumption at different doses (consumed three times per week (3x\u002Fwk)) on changes in fasting and postprandial lipid metabolism\u002Fblood lipids and markers of chronic disease risk.\n\nThe specific aims are: \\*Examine the impact of intermittent CSO consumption (3x\u002Fweek) at two different doses on fasting and postprandial lipids. \\*Examine the impact of intermittent CSO consumption (3x\u002Fweek) at two different doses on other markers of chronic disease risk.\n\nParticipants will be asked to:\n\n\\*Consume provided meal replacement shakes and snacks 3 times per week for 56 days. \\*Attend three bi-weekly (every other week) short visits for fasting blood draws, body measurements, and collection of the next two weeks' study materials. \\*Attend two longer (5.5h) testing visits, which include eating a standardized breakfast meal and having blood drawn periodically before and after breakfast.\n\nResearchers will compare CSO-30, CSO-20, and Control groups (receiving no oil) to see if intermittent CSO consumption imparts the same health benefits as previously shown with daily doses of CSO.","Accounting for nearly 1 in every 4 deaths in the U.S., cardiovascular disease (CVD) is the leading cause of death for adults. One risk factor for CVD is hypercholesterolemia, which can double the risk for this disease. Cottonseed oil is a rich source of polyunsaturated fatty acids (PUFAs). Despite having a relatively high amount of saturated fatty acids, preliminary studies demonstrate that incorporating CSO into a diet at 30% and 20% of daily energy needs is sufficient to reduce blood lipid profiles and select postprandial measures of metabolism. These improvements in lipid metabolism may be due to the general fatty acid (FA) composition of CSO; however, evidence shows that a fatty acid unique to CSO, dihydrosterculic acid (DHSA), may be responsible for some, if not all, of the positive lipid lowering effects.\n\nThis prospective clinical study is a double-blinded, randomized control trial in adults at increased risk for cardiovascular disease (poor cholesterol profiles and\u002For overweight\u002Fobesity). There are three diet interventions: CSO-30 (30% of energy needs from CSO), CSO-20 (20% of energy needs from CSO), and Control (not receiving CSO; will receive thickened water with yellow food coloring to mimic the appearance of oil). The study protocol consists of a 56-day intervention where participants are provided breakfast shakes and snacks that contain different amounts of oil, depending on the participant's random group assignment.\n\nThere are a total of 6 testing visits: screening (v0), pre-intervention (v1), 3 bi-weekly (every other week) short visits (v2, v3, v4), and post-intervention (v5).\n\nAt screening (v0), qualification is confirmed based on anthropometrics and a fasting blood draw, which is analyzed for a cholesterol panel and blood glucose. Additionally, energy requirements are estimated at this visit for use in the diet intervention.\n\nAt v1, participants will have anthropometrics measured, including body composition by dual-energy x-ray absorptiometry (DXA). Fasting and postprandial blood draws for a 5h period will occur following a high saturated-fat meal challenge which delivers 35% of the participant's estimated energy needs.\n\n56-day dietary intervention: Participants will consume a shake and snack 3 times per week, corresponding to the participant's randomly assigned group. The ingredients for the breakfast shakes and snacks are identical between groups, the only difference being the amount of assigned oil provided. The breakfast shakes and snacks are portioned based on individual energy needs as estimated at v0.\n\nParticipants return every other week (v2, v3, v4), to return study materials and collect shakes and snacks for the next two weeks. At these bi-weekly visits, participants also have a fasting blood draw and body measures taken.\n\nAt the end of the 56-day dietary intervention, participants return for v5, where all procedures from v1 are repeated.\n\nAs decided a priori, we will complete a per protocol analysis.\n\nThe investigators hypothesize that CSO-30 and CSO-20 will improve the proposed overall health outcomes and markers of chronic disease risk without changing inflammatory markers or coagulation potential compared to the control group.",[19,20,21],"Dyslipidemia","Overweight and Obesity","Nutrition, Healthy",[],"INTERVENTIONAL","PREVENTION",[26],"NA",{"count":28,"type":29},75,"ESTIMATED",[31,35,39],{"type":14,"name":32,"description":33,"armGroupLabels":34},"CSO-30","Participants are provided a breakfast shake and snack to consume 3 times per week that meets 30% of participant's daily estimated energy needs as cottonseed oil for 56 days.",[32],{"type":14,"name":36,"description":37,"armGroupLabels":38},"CSO-20","Participants are provided a breakfast shake and snack to consume 3 times per week that meets 20% of participant's daily estimated energy needs as cottonseed oil for 56 days.",[36],{"type":14,"name":40,"description":41,"armGroupLabels":42},"Control","Participants are provided a breakfast shake and snack to consume 3 times per week that does not contain cottonseed oil, but does contain thickened water for blinding purposes, for 56 days.",[40],[44,48,51,54,57,60,63,66,69,72],{"measure":45,"description":46,"timeFrame":47},"Change in fasting serum lipoprotein and cholesterol concentrations","The concentration of fasting serum total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, cholesterol\u002FHDL ratio, and non-HDL cholesterol (mg\u002FdL)","baseline, 8 weeks",{"measure":49,"description":50,"timeFrame":47},"Change in fasting and postprandial plasma triglyceride concentrations","The concentration of plasma triglycerides before and after the high saturated fat meal challenge at both pre-and post-intervention visits (mg\u002FdL)",{"measure":52,"description":53,"timeFrame":47},"Change in fasting and postprandial plasma non-esterified fatty acid (NEFA) concentrations","The concentration of plasma NEFAs before and after the high saturated fat meal challenge at both pre- and post-intervention visits (mEq\u002FL)",{"measure":55,"description":56,"timeFrame":47},"Change in fasting and postprandial plasma appetite control hormone concentrations","The concentration of plasma appetite control hormones before and after the high saturated fat meal challenge at both pre- and post-intervention visits.
