Grapefruit (Citrus paradisi Macf.) is an important cultivar of the Citrus genus which contains a number of nutrients beneficial to human health. The objective of the present study was to evaluate changes in bioactive flavonoids, antioxidant behaviour, and in vitro cytoprotective effect of processed white and pink peels after oven-drying (45°C-60°C) and freeze-drying treatments. Comparison with ...

Tramadol is a centrally acting analgesic drug extensively metabolized in animal species. Its clinicalresponse is mainly due to the M1 metabolite, poorly produced in dogs. Grapefruit-juice can inhibit themetabolism of different drugs in animals and humans. The aim of the present study was to evaluate thepharmacokinetics of tramadol and its major metabolites after co-administration of tramadol an...

Three middle-aged males and one female were diagnosed as having urinary tract infections (UTIs) between 2001 and 2003 in the Wesley Guild Hospital, Ilesa, a unit of Obafemi Awolowo University Teaching Hospitals Complex, Ile Ife, Osun State, Nigeria. Of the 4 patients, only the female was asymptomatic. The 3 males had Pseudomonas aeruginosa, Klebsiella species, and Staphylococcus aureus, respect...

Grapefruit juice increases the oral availability of a variety of CYP3A4 substrates. It has been shown that recurrent grapefruit juice ingestion results in a loss of CYP3A4 from the small bowel epithelium. We now show that the reduction in intestinal CYP3A4 concentration is rapid; a 47% decrease occurred in a healthy volunteer within 4 hr after consuming grapefruit juice. To identify the specifi...

Florida is the main producer of grapefruit (Citrus paradisi Macf.) in the world. Grapefruit provide not only the traditional nutrients (carbohydrates, proteins, vitamins, minerals), but also phytochemicals such as fl avonoids, which are not essential for life, but may provide many health benefi ts. Flavanones are the dominant fl avonoids, and account for about 98% of the total fl avonoids in gr...

BACKGROUND Dietary guidance recommends consumption of a nutrient-dense diet containing a variety of fruits. The purpose of this study was to estimate usual nutrient intakes and adequacy of nutrient intakes among adult grapefruit consumers and non-consumers, and to examine associations between grapefruit consumption and select health parameters. METHODS The analysis was conducted with data col...
