About

This study evaluates the effects of a prescribed 4-week raw, plant-based dietary intervention in the treatment of excess body weight, hypercholesterolemia, and hypertension in the clinical setting.

Full description

Plant-based diets have emerged in the literature as effective therapeutic strategies in the reduction of body weight, serum lipids and blood pressure. In addition, raw fruit and vegetable consumption has also been associated with the reduction of these clinical indicators.

Participants were instructed to follow a prescribed, raw, plant-based dietary intervention for four weeks. All animal products, including eggs and dairy, were excluded. Cooked foods, free oils, soda, alcohol and coffee were also to be excluded. All meals and snacks were provided to the participants for the full duration of the intervention. Emphasized were raw fruits and vegetables, while seeds, avocado, raw oats, raw buckwheat, and dehydrated foods were prepared as condiments. Vitamin, herbal, and mineral supplements were to be discontinued unless otherwise clinically indicated. Participants were not advised to alter their exercise habits.

Participants came to a total of 4 follow-up visits. A laboratory panel was obtained at baseline and at 4-weeks. A 24-hour recall was also conducted at baseline and at 4-weeks. Anthropometrics, hemodynamics, and medication needs were assessed on a weekly basis.
