1)low fiber control,.
2)whole grain barley, and.
3)whole grain oats. The intervention included food products that were incorporated into a controlled 7-day menu rotation that were served to volunteers for 6 weeks. Products included breakfast cereal, granola, trail mix, and fruit-cereal bars to achieve 4 to 8 servings of whole grain intake per day. Subjects (n=69, approximately equal number of men and women) were stratified by gender and initial body mass index (BMI), and randomly assigned to a treatment. At the end of the intervention, blood and urine samples were collected, and during the past year, these samples have been analyzed for treatment differences in long-term biomarkers of glucoregulatory control and cardiovascular disease. The second study was a randomized, double-blind, crossover intervention to investigate the health effects of acute ingestion of whole grain barley and oats. The study included three treatments: .
1)a high fat, low fiber control meal,.
2)a high fat meal including whole grain barley, and.
3)a high fat meal containing whole grain oats. Subjects (n=18, approximately equal number of men and women) were randomly assigned to a treatment sequence. At the end of the intervention period, subjects underwent a meal tolerance test or an assessment of blood vessel reactivity. During the past year, blood samples were analyzed for glucose and fat appearance after the meal. Data interpretation is underway.
