A cluster of risk factors for cardiovascular disease and type 2 diabetes mellitus have become known as the Metabolic Syndrome (MetS). In the United Arab Emirates, 42% of the population was diagnosed with MetS. Previous researchers observed the anti-diabetic, hypolipidemic anti-oxidative, anti-inflammatory and antiantitumorigenic properties of spices on body composition, blood parameters and blood pressure. The aim of the study was to assess the macronutrient, micronutrient, sugar and caffeine content for seven commonly consumed spices. Moreover, the aim of the study was to measure the effect of ginger (Zingiber officinale), cinnamon (Cinnamomum) and black seed (Nigella sativa) consumption on blood glucose, lipid profile and body composition in participants at risk of cardiovascular diseases.
Seven spices were analyzed to investigate their proximate content, minerals, vitamins, sugars and caffeine. One hundred and twenty (N=120) participants with risk of cardiovascular diseases were randomly allocated to three treatment arms (ginger, cinnamon and black seed) and a control group (placebo) for a period of 12-weeks. Each participant consumed 3 g/day of powder (spice or placebo). Data related to different parameters were collected from participants at baseline, midpoint and at endpoint of the intervention.
Analysis of the chemical composition of spices showed that the spices had considerable amount of macronutrients (especially oils) and micronutrients. Therefore, spices’ active compounds could be used in nutritional supplements and for treatments considering their decent source of valuable nutrients. Furthermore, consumption of spices powder significantly improved waist circumference, body fat mass, weight, body mass index, percent body fat, fasting blood glucose and triglycerides when compared to placebo group (P ≤ 0.05). Ingestion of 3 grams per day for 12 weeks of spices powder showed significant improvement in body composition, blood glucose and lipid profile. Overall this study demonstrates that the consumption of ginger, cinnamon and black seed powder could help in the management of cardiovascular risk factors.
