<subfield code="a">Introduction The intake of polyphenols has certain health&#xd;
benefits. This study will aim to assess the effect of adding&#xd;
a daily amount of chocolate high in cocoa content and&#xd;
polyphenols to the normal diet on blood pressure, vascular&#xd;
function, cognitive performance, quality of life and body&#xd;
composition in postmenopausal women.&#xd;
Methods and analysis Here we plan a randomised&#xd;
clinical trial with two parallel groups involving a&#xd;
total of 140 women between 50 and 64 years in the&#xd;
postmenopausal period, defined by amenorrhoea of at&#xd;
least 12 consecutive months. The main variable will be&#xd;
the change in blood pressure. Secondary variables will&#xd;
be changes in vascular function, quality of life, cognitive&#xd;
performance and body composition. The intervention&#xd;
group will be given chocolate containing 99% cocoa, with&#xd;
instructions to add 10 g daily to their normal diet for 6&#xd;
months. The daily nutritional contribution of this amount&#xd;
of chocolate is 59 kcal and 65.4 mg of polyphenols. There&#xd;
will be no intervention in the control group. All variables&#xd;
will be measured at the baseline visit and 3 and 6 months&#xd;
after randomisation, except cognitive performance and&#xd;
quality of life, which will only be assessed at baseline and&#xd;
at 6 months. Recruitment is scheduled to begin on 1 June&#xd;
2018, and the study will continue until 31 May 2019.&#xd;
Ethics and dissemination This study was approved&#xd;
by the Clinical Research Ethics Committee of the Health&#xd;
Area of Salamanca, Spain (‘CREC of Health Area of&#xd;
Salamanca’), in February 2018. A SPIRIT checklist is&#xd;
available for this protocol. The clinical trial has been&#xd;
registered at ClinicalTrials. gov provided by the US National&#xd;
Library of Medicine, number NCT03492983. The results&#xd;
will be disseminated through open access peer-reviewed&#xd;
journals, conference presentations, broadcast media and a&#xd;
presentation to stakeholders.</subfield>
