Study Details

Detailed Description
The Nutritional Research Foundation, in conjunction with Northern Arizona University, is conducting a long-term health study for women ages 18 and older. This study will address the effects of a nutrient dense, plant-rich diet on the long-term risks of cancer and other chronic diseases.
Participants enroll in a 30-day training module which outlines the benefits of a nutrient-dense, plant-rich diet. At the conclusion of those videos and written modules, they take a short quiz to assess their knowledge and they can enroll in the full study.
All participation is online with ongoing modules on nutrition and lifestyle. There is a comprehensive health history and lifestyle index to be completed. Nutrition questionnaires will be administered an average of every 3-6 months; PHQ-9 (Patient Health Questionnaire) & PSQI (Pittsburgh Sleep Quality Index) questionnaires an average of every 12 months; serum cardiometabolic measures and liquid biopsies an average of every 18 months.

|---|---|
| Experimental: Intervention for all participants Nutritarian Diet-style: Intervention for all participants: All participants are exposed to the same nutrition treatment/intervention protocol. |
Other: Nutritarian Diet-style
Nutritarian Diet-style: Daily consumption of greens, beans/legumes, a variety of other vegetables, fresh or frozen fruits, nuts, seeds and whole grains. Participants are encouraged to minimize consumption of refined grains, vegetable oils, processed foods, and to limit animal products.

Outcome Measures
Primary Outcome Measures
- Nutrition Intervention [Every 12 months, up to 10 years.]
Adherence to the recommended dietary protocol with the Nutritarian Health Indicator (©Joel Furhman MD). Scored by points (90-100 excellent, 80-89 good, 70-79 average, <69 poor).
Secondary Outcome Measures
- Weight Management [Every 12 months, up to 10 years.]
Height/weight/BMI of participants through self-reported measurements. Weight and height will be combined to report BMI in kg/m^2.
- Waist Measurement [Every 12 months, up to 10 years.]
Self-measured and reported measurements in inches.
- Hip Measurement [Every 12 months, up to 10 years.]
Self-measured and reported measurements in inches.
- Mental Health [Every 12 months, up to 10 years.]
PHQ-9 (Patient Health Questionnaire-9). Tool designed for screening, diagnosing, monitoring and measuring the severity of depression. Scoring: 5-9 (minimal symptoms), 10-14 (minor depression, dysthymia, mild major depression), 15-19 (major depression, moderately severe), and >20 (major depression, severe).
- Sleep quality assessment [Every 12 months, up to 10 years.]
PSQI (Pittsburgh Sleep Quality Index). Tool designed to evaluate sleep quality over a 1 month interval. Scoring 0-21 points. Any score >5 indicates sleep impairment, with higher scores designating poorer sleep and greater impact on daily life.
- Cancer prevalence [Every 12 months, up to 10 years.]
Self-reported occurrence, recurrence, and progression of cancer at any site. Will be expressed as frequency distribution across the study population.
- Chronic disease prevalence [Every 12 months, up to 10 years.]
Self-reported occurrence, recurrence, and progression of chronic disease (diabetes, cardiovascular disease, inflammatory disease). Will be expressed as frequency distribution across the study population.
