Hemp Seed Protein and Bioactive Peptides Consumption for Hypertension

This clinical trial is being conducted to study the effect of whole hemp seed protein, hemp seed protein hydrolysate derived bioactive peptide and casein protein consumption on systolic and diastolic ambulatory blood pressure. This study is will be conducted in 35 hypertensive participants aged between ≥18 and ≤75 yrs who have systolic blood pressure higher than 130 mmHg or diastolic blood pressure ≤ 110 mmHg. The study will consist of 3 periods of 42 days each during which participants will consume assigned treatment. Consumption of treatments will be from days 1 to 42. There will also be a washout period of a minimum of 14 days between the 3 treatment periods where the participants can consume their habitual diets. The entire study is designed to take 22 weeks from start to completion. The participants will consume the assigned treatment twice a day. The treatments are in the form of a smoothie and the smoothies will consist of frozen fruit, fruit juice, frozen yoghurt/sorbet, and 25 g of protein from treatment protein powder which is 25 grams of casein protein, 25 grams of hemp seed protein, or 22.5 grams of hemp seed protein and 2.5 grams of hemp seed protein hydrolysate derived bioactive peptides. On days 1 and 42 of each treatment period of the trial, body weight, waist and hip circumference, blood pressure, pulse wave velocity (PWV) and augmentation index (AI) will be measured. Ambulatory blood pressure (ABP) over 24 hours will also be measured on day 1 of phase 1 and day 42 of each treatment period of the trial.
