Hydroponic vs Conventional Spinach Smoothies: Effects on Salivary Nitrate Bioavailability and Blood Pressure

Sponsor: University of Plymouth

Summary

The goal of this clinical trial is to determine whether hydroponic spinach (HS) versus conventional spinach (CS) smoothies produce differential post-consumption effects on salivary nitrate availability and blood pressure in adults. The main questions it aims to answer are: Do hydroponic spinach (HS) and conventional spinach (CS) smoothies produce differential post-consumption salivary nitrate availability responses in adults when consumed in equal volumes? Do hydroponic spinach (HS) and conventional spinach (CS) smoothies produce differential post-consumption blood pressure responses in adults when consumed in equal volumes? Participants will: Consume hydroponic spinach (HS) and conventional spinach (CS) smoothies on two separate study days. Attend two laboratory visits at the university, scheduled within a 1-2 week period. Undergo check-ups and study measurements during each visit (e.g., blood pressure and saliva sampling).
