About this study
Official title: Effect of Tahini Consumption on Oxidative Stress and Inflammation Markers as Well as Endothelial Function and Arterial Stiffness in Healthy Volunteers
Cardiovascular disease (CVD), a cluster of disorders that affect heart and blood vessels, is the leading cause of morbidity and mortality around the world and is responsible for 17.9 million deaths annually worldwide. CVD risk factors can be modifiable (nutrition, physical activity, obesity, smoking, hyperlipidemia, hypertension and diabetes) and non-modifiable (age, gender, ethnicity, family history and socioeconomic status). Chronic exposure to CVD risk factors induces oxidative stress and promotes inflammation. In addition, endothelial cells in response to the inflammatory reaction secrete growth factors, leading to the destruction of vascular endothelium and promoting atherogenesis.
Oxidative stress refers to the imbalance between anti-oxidant and pro-oxidant compounds, with predominance of the pro-oxidant ones. Reactive Oxygen Species overproduction has been implicated in pathogenesis and complications of numerous diseases including diabetes, cardiovascular diseases, cancer, neurodegenerative diseases and chronic kidney disease.

Moreover, endothelium consists of a single layer of endothelial cells; it is the natural barrier between blood and tissues and also an endocrine organ. It plays a key role in vascular homeostasis by maintaining a balance between vasodilation and vasoconstriction and is responsible for fluid filtration, blood vessel tone, hormone trafficking, hemostasis, regulation of blood flow and growth of blood vessels. Thus, reductions in endothelial function are detrimental and predict and precede the development of overt CVD.
Sesame belongs to Pedaliaceae family and can be consumed in different forms such as seeds, oil or tahini, i.e., a 100 % peeled, ground and roasted sesame paste. Sesame seeds are rich in polyunsaturated fatty acids, proteins, vitamin E and lignans, such as sesamin, sesamolin and sesamol. Recent studies have highlighted the antioxidant, antihypertensive, hypolipidemic and appetite control properties of sesame seeds and sesame oil.
Regarding the consumption of tahini and its effect on human health, only three studies are available in the current literature, one of them in patients with type 2 diabetes, one in diabetic animal model and one in Alzheimer's disease animal model. Thus, the aim of the present study is to investigate the effect of tahini consumption on oxidative stress, blood pressure, endothelial function and arterial stiffness in healthy males postprandially.
Read the detailed description
Cardiovascular disease (CVD), a cluster of disorders that affect heart and blood vessels, is the leading cause of morbidity and mortality around the world and is responsible for 17.9 million deaths annually worldwide. CVD includes coronary heart disease, peripheral arterial disease, cerebrovascular disease, rheumatic heart disease, congenital heart disease, deep vein thrombosis and pulmonary embolism. CVD risk factors can be modifiable (nutrition, physical activity, obesity, smoking, hyperlipidemia, hypertension and diabetes) and non-modifiable (age, gender, ethnicity, family history and socioeconomic status). Chronic exposure to CVD risk factors induces oxidative stress and promotes inflammation. In addition, endothelial cells in response to the inflammatory reaction secrete growth factors, leading to the destruction of vascular endothelium and promoting atherogenesis.
Oxidative stress refers to the imbalance between anti-oxidant and pro-oxidant compounds, with predominance of the pro-oxidant ones. These compounds are also called Reactive Oxygen Species (ROS) or free radicals and are unstable atoms or molecules. Their generation, as products of normal cellular metabolism, occurs naturally by endogenous sources (e.g. mitochondria, peroxisomes and endoplasmic reticulum) through enzymatic and non-enzymatic reactions. Furthermore, exogenous sources implicated in free radical production are air pollution, alcohol consumption, tobacco smoking, ultraviolet light exposure, industrial solvents and others. Free radical production is regulated by the well-organized human endogenous enzymatic and non-enzymatic antioxidant system, along with the exogenous antioxidants found in food. However, in some cases antioxidant system fails to eliminate ROS overproduction and can consequently induce serious damage to important for life biomolecules (DNA, lipids, proteins), leading to cell injury and death. Thus, ROS overproduction has been implicated in pathogenesis and complications of numerous diseases including diabetes, cardiovascular diseases, cancer, neurodegenerative diseases and chronic kidney disease.
Moreover, endothelium consists of a single layer of endothelial cells; it is the natural barrier between blood and tissues and also an endocrine organ. It plays a key role in vascular homeostasis by maintaining a balance between vasodilation and vasoconstriction. Moreover, vascular endothelium is responsible for fluid filtration, blood vessel tone, hormone trafficking, hemostasis, regulation of blood flow and growth of blood vessels. Thus, reductions in endothelial function are detrimental and predict and precede the development of overt CVD.
Sesame belongs to Pedaliaceae family and can be consumed in different forms such as seeds, oil or tahini, i.e., a 100 % peeled, ground and roasted sesame paste. Sesame seeds are rich in polyunsaturated fatty acids (PUFAs), proteins, vitamin E and lignans, such as sesamin, sesamolin and sesamol. Recent studies have highlighted the antioxidant, antihypertensive, hypolipidemic and appetite control properties of sesame seeds and sesame oil. Moreover, few studies have investigated the effect of sesame consumption on blood pressure, endothelial function and arterial stiffness in human population. According to a metanalysis, sesame consumed in form of seed, oil, capsule or bar decreased both systolic blood pressure (SBP) and diastolic blood pressure (DBP), while sesame oil consumption was found to improve endothelial function both in the postprandial state and after long term consumption in hypertensive men.
Regarding the consumption of tahini and its effect on human health, only three studies are available in the current literature, one of them in patients with type 2 diabetes, one in diabetic animal model and one in Alzheimer's disease animal model. Thus, the aim of the present study is to investigate the effect of tahini consumption on oxidative stress, blood pressure, endothelial function and arterial stiffness in healthy males postprandially.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Cardiovascular disease (CVD), a cluster of disorders that affect heart and blood vessels, is the leading cause of morbidity and mortality around the world and is responsible for 17.9 million deaths annually worldwide. CVD risk factors can be modifiable (nutrition, physical activity, obesity, smoking, hyperlipidemia, hypertension and diabetes) and non-modifiable (age, gender, ethnicity, family history and socioeconomic status). Chronic exposure to CVD risk factors induces oxidative stress and promotes inflammation. In addition, endothelial cells in response to the inflammatory reaction secrete growth factors, leading to the destruction of vascular endothelium and promoting atherogenesis.
Oxidative stress refers to the imbalance between anti-oxidant and pro-oxidant compounds, with predominance of the pro-oxidant ones. Reactive Oxygen Species overproduction has been implicated in pathogenesis and complications of numerous diseases including diabetes, cardiovascular diseases, cancer, neurodegenerative diseases and chronic kidney disease.

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Concentration of oxidative stress biomarkers (time frame: Four hours after tahini consumption). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04608747, which also lists 23 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Oct 2020.
