This article delves into the nutritional powerhouse that is broccoli, exploring its multifaceted health benefits. From its rich array of vitamins and minerals to its potent antimicrobial properties and anti-inflammatory prowess, broccoli stands as a stalwart in promoting overall well-being. The cruciferous vegetable broccoli is a rich source of several important nutrients, including fiber, vitamins (A, C and K), minerals (calcium, potassium and iron) and antioxidants. It has also been shown to contain bioactive compounds such as glucosinolates, sulforaphane and indole-3-carbinol, all of which have been shown to have significant health-promoting effects. Through a comprehensive examination of its components, we uncover the science behind broccoli's positive impact on human health. As we unravel the layers of its nutritional prowess, this article serves as a guide to understanding and appreciating the bountiful benefits that broccoli brings to the table.

Cancer remains a formidable global health challenge, necessitating a multifaceted approach for prevention and treatment. Recent research has shed light on the intricate interplay between micronutrients and gene regulation in antioxidant vitamin pathways, unveiling promising avenues for enhancing the body's natural defenses against cancer. This article explores the pivotal role of micronutrients, particularly antioxidant vitamins, in modulating gene expression and influencing key pathways involved in cancer prevention. By understanding the molecular mechanisms at play, we can harness the power of nutrition to nourish the fight against cancer.

Broiler breeder stocks are characterised by low egg fertility and hatchability which could be mitigated by dietary Vitamin E (VE) supplements. The optimum vitamin E requirements for efficient production by Arbor Acres plus broiler breeder hens in Ibadan were investigated in this study. Arbor Acres plus broiler breeder hens (n=180) weighing 3.85 ± 0.49 kg, aged 30 weeks were randomly allotted to diets supplemented with synthetic VE at 0, 20, 40, 60, 80, 100 IU/kg for eight weeks in a completely randomised design. Hatchability of 86.4 ± 1.9% in hens fed diets supplemented with 100IU was significantly lower (p<0.05) than in those on 0 (93.3 ± 1.8%), 20 (92.9 ± 2.0%), 40 (96.9+1.5%), 60 (93.2 ± 0.9%) and 80 IU (91.2 ± 1.7%). Weight of 42.9 ± 1.3 g in chicks on 40 IU was significantly higher (p<0.05) than 36.9 ± 1.5 g (0IU), 40.2 ± 1.3g (20IU), 39.1 ± 1.2 g (60IU), 40.0 ± 0.6 g (80IU) and 39.3 ± 0.6 g (100IU). The relationships between VE inclusions and hatchability (R2=0.63); and chick weights (R²=0.56) were quadratic and cubic, respectively. Optimal egg hatchability of 94.8% and chicks’ weight of 41 g were achieved with diets supplemented with 37 IU/kg and 24 IU/kg supplemental VE inclusions, respectively. Thus, the dietary supplement of vitamin E enhanced the fertility and hatchability of Arbor Acres plus breeder broiler hens in Ibadan, Nigeria.
