One of the causes of stroke which can be treated is narrowing of the carotid artery. Currently the only definite treatment option is surgery or endovascular treatment. All patients not qualified for or awaiting surgery are, therefore, left with best medical therapy and with a yearly risk of stroke anywhere between 1% - 35% depending on the severity of the disease.\n\nThe study will use the properties of a tomato extract containing lycopene. Previously studies have demonstrated beneficial properties of tomato extracts:\n\n1. It decreases lipid oxidation\n2. It decreases DNA damage\n3. It has properties that reduce the speed and amount of cell divisions that inflammatory and smooth muscle cells undergo (both of these cell types contribute to atheroma formation).\n\nThe investigators wish to assess whether long-term food supplementation with a tomato extract containing lycopene could influence atherosclerotic plaque characteristics. The investigators will assess this using Magnetic Resonance Imaging of the plaque and transcranial Doppler ultrasonography for counting the number of blood clots that go to the brain's arteries. Furthermore the investigators wish to examine the effect of long-term food supplementation with a tomato extract containing lycopene on blood cholesterol levels and lipid oxidation and blood markers of inflammation and injury of the inner lining of the arteries.\n\nThis will be a single center, double blind, randomised, placebo controlled study."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '90 Years', 'minimumAge': '40 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age 40 - 90 years old,\n* Clinically documented carotid symptomatic atherosclerotic disease (symptomatic disease will be considered if one of the following has occurred within 2 months prior to symptoms:\n\n 1.
