Background: We developed a WASHOKU-modified DASH diet named DASH-JUMP.
We previously reported the hypotensive effect of the DASH-JUMP diet in Japanese participants
with untreated high-normal Blood Pressure (BP) or stage 1 hypertension.
Objective: We aim to introduce the DASH-JUMP diet worldwide as a new lifestyle medicine.
Accordingly, we prospectively assessed the nutritional characteristics of the DASH-JUMP diet.
Methods: Participants were treated with the DASH-JUMP diet for 2 months. Then, for 4 months
after the intervention, they consumed their usual diets. We conducted a nutritional survey using the
FFQg nutrient questionnaire at baseline and after 1, 2, 3, and 6 months. We received completed
questionnaires from 55 participants (28 men and 27 women; mean age 54.2 ± 8.0 years) and
Results: The DASH-JUMP diet is rich in green-yellow vegetables, seaweed, milk, and mushrooms,
while it has low contents of meat, eggs, confectionery, oils and fats, pickles, shellfish boiled in
sweetened soy sauce, and fruits. Nutrients significantly associated with the observed change in systolic
BP were niacin (P = 0.005) and carbohydrate (P = 0.033). The results of the FFQg questionnaire
revealed that participants who had an increased BP at 1 month after ceasing the intervention
had eating habits that broadly imitated the DASH-JUMP diet at 4 months after ceasing the intervention.
Therefore, the systolic and diastolic BP values at 4 months after ceasing the intervention decreased
significantly compared to those at baseline.
Conclusion: The DASH-JUMP diet may represent a new lifestyle medicine for reducing hypertension.
