  Purpose
The purpose of this study is to determine if the inclusion of 1.5 ounces of pumpkin seeds per day in the diet of women will alter dietary fatty acid intake or blood pressure.

Condition Intervention
Cardiovascular Disease Blood Pressure Other: Pumpkin Seeds

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Prevention
Official Title: Effect of Pumpkin Seeds on the Dietary Fatty Acid Intake and Blood Pressure in Women

Further study details as provided by Texas Woman's University:

Primary Outcome Measures:
  • Dietary fatty acid intake [ Time Frame: 12 weeks ]
    The dietary fatty acid intake, specifically monounsaturated and polyunsaturated fatty acids, will be measured three times over the course of a twelve week period to determine if fatty acid intake changed during the intervention.

  • Blood pressure [ Time Frame: 12 weeks ]
    Blood pressure will be measured at every meeting to determine if the addition of pumpkin seeds to the diet altered blood pressure.

Arms Assigned Interventions
Active Comparator: Group I - Pumpkin Seeds
First four weeks of study: consume perceived normal diet; Second four weeks of study: receive 1.5 ounces of pumpkin seeds per day for consumption; Third four weeks of the study: consume their perceived normal diet.
Other: Pumpkin Seeds
Participants will be asked to consume 1.5 ounces of raw, unsalted pumpkin seeds per day. The 1.5 ounces will be split in to two servings (each 0.75 ounces).
Active Comparator: Group II - Pumpkin Seeds
First four weeks of study: consume perceived normal diet; Second four week period: consume perceived normal diet; Third four week period: receive 1.5 ounces of pumpkin seeds per day for consumption.
Other: Pumpkin Seeds
Participants will be asked to consume 1.5 ounces of raw, unsalted pumpkin seeds per day. The 1.5 ounces will be split in to two servings (each 0.75 ounces).

Detailed Description:
Cardiovascular disease is the number one cause of morbidity and mortality in United States. Diets high in polyunsaturated and monounsaturated fatty acids have been shown to decrease the risk of cardiovascular disease. Pumpkin seeds are a good source of monounsaturated and polyunsaturated fatty acids. Oil extracted from pumpkin seeds has been shown to lower blood pressure. One purpose of this study is to determine whether eating 1.5 ounces of pumpkin seeds per day will improve polyunsaturated and monounsaturated fatty acid intake in the diet in healthy adult women. Another purpose of this study is to determine whether eating 1.5 ounces of pumpkin seeds a day will lower blood pressure.
