About this trial

Cardiovascular disease risk factors, including higher BMIs and poor cholesterol profiles, are on the rise and contribute to the United States' growing disease burden. 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/wk)) on changes in fasting and postprandial lipid metabolism/blood lipids and markers of chronic disease risk.

The specific aims are: \*Examine the impact of intermittent CSO consumption (3x/week) at two different doses on fasting and postprandial lipids. \*Examine the impact of intermittent CSO consumption (3x/week) at two different doses on other markers of chronic disease risk.

Participants will be asked to:

\*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.

Researchers 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.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

25-75 year-old men and women at increased risk for cardiovascular disease. Increased risk for cardiovascular disease will be defined by either elevated cholesterol profiles -or- overweight/obesity.

"Borderline High" and/or "at risk" in two of more of the following variables (total cholesterol: 180-239 mg/dL, LDL cholesterol 110-159 mg/dL, triglycerides 130-199 mg/dL) --or--

"High" in total cholesterol (240 mg/dL and higher), LDL (160 mg/dL or higher), or triglycerides (between 200-350 mg/dL).

Disqualifiers

Probable familial hypercholesterolemia, defined by: total cholesterol greater than 290 mg/dL or LDL levels greater than 190 mg/dL plus a family history of myocardial infarction (MI) before 50 years of age in a 2nd-degree relative or below age 60 in a 1st-degree relative.

Women on hormone replacement therapy less than 2 years.

Women who are pregnant or nursing/breastfeeding

individuals who regularly exercise more than 3h/w

Parallel

Treatments tested in this trial

  • CSO-30

    Other intervention

    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.

  • CSO-20

    Other intervention

    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.

  • Control

    Other intervention

    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.
