Brief summary
The purpose of this clinical study is to evaluate the health properties of a dietary intervention carried on with an innovative low-salt bread. The hypothesis is that the introduction of a low-sodium bread as part of a low-salt diet may improve the compliance to the own regime and that the vascular function, the inflammatory and oxidative state, the composition of the intestinal microbiota and that neurocognitive and neurodegenerative processes can improve in hypertensive patients fed a low-salt diet with low-salt bread.
Detailed description
This clinical trial is a multi-center, randomized, controlled, open label, pilot study, lasting 6 months. A target number of seventy individuals with hypertension meeting inclusion and exclusion criteria, assessed at enrollment, and which have signed the informed consent, will be recruited.
Interventions
low-sodium diet (2300 mg Na/die) with use of standard bread (750 mg Na/100g) for 6 months
low-sodium diet (2300 mg Na/die) with use of low-salt bread (280 mg Na/100g) for 6 months
