An increasing body of evidence on the association between adherence to the Mediterranean diet and healthy status is being accumulated. Floral buds of Capparis spinosa L. are commonly used in the Mediterranean cuisine as flavoring for meat and other foods. The present study evaluated bioactive components and antioxidant activity of Sicilian capers stabilized in salt. Whereas alpha-tocopherol was...

Kedelai adalah produk pangan bernilai gizi tinggi yang banyak dikonsumsi oleh masyarakat Indonesia. Pada penelitian ini, kedelai dimodifikasi dengan cara perkecambahan. Komponen zat akan berubah menjadi senyawa-senyawa lebih sederhana selama proses perkecambahan sehingga mudah dicerna bagi tubuh manusia. Selain itu, juga dapat meningkatkan kapasitas antioksidan. Tujuan dari ini menentukan kondi...

In contrast to strong epidemiologic, preclinical, and secondary clinical evidence for vitamin E (tocopherols) in reducing cancer risk, large-scale clinical cancer-prevention trials of a-tocopherol have been negative. This vexing contrast helped spur substantial preclinical efforts to better understand and improve the antineoplastic activity of tocopherol through, for example, the study of diffe...

BACKGROUND Blood lipids can influence fat-soluble antioxidant concentrations and confound their interpretation as indicators of antioxidant intake status and disease risk. OBJECTIVES The objectives were to identify lipoproteins that can confound the interpretation of serum fat-soluble antioxidants, to evaluate the amount of the confounding, and to recommend a method for standardizing blood co...

BACKGROUND The role of antioxidants in the pathogenesis of type 2 diabetes is uncertain. OBJECTIVE We evaluated cross-sectional relations of dietary intakes and plasma concentrations of antioxidants with glucose metabolism in a high-risk population. DESIGN The subjects were 81 male and 101 female first- and second-degree, nondiabetic relatives of patients with type 2 diabetes. Antioxidant i...

Much of our knowledge about the relationship between micronutrients and cancer comes from studies in which plasma (serum) micronutrient levels have been correlated with cancer incidence; however, the relationship between the concentrations of micronutrients in the plasma and in the target tissues has not been established. Ninety-three subjects (62 males and 31 females ages 42-86, median age 69)...

This study was performed to examine the postprandial effects of meals containing dietary fats, with their natural fatty acid composition and tocopherol content, on the plasma triacylglycerols (TG) and tocopherols and on the resistance of VLDL and LDL to oxidation. On six separate days eighteen healthy male subjects were given low-fat meals (LF) or the LF meals enriched with sunflower oil (SO), ...

Twenty-four crossbred beef cows were used to investigate the concentration of alpha-tocopherol in plasma and tissues following oral administration of four tocopherol sources. Animals were allotted to the following treatments: DL-alpha-tocopherol, D-alpha-tocopherol, DL-tocopheryl acetate and D-alpha-tocopheryl acetate. Animals received a daily oral dose of 1,000 IU of the respective tocopherol ...

The oxidative modification of low density lipoprotein (LDL) may play an important role in atherogenesis. Antioxidants that can prevent LDL oxidation may act as antiatherogens. Our understanding of the mechanism of LDL oxidation and factors that determine its susceptibility to oxidation is still incomplete. Copper is a candidate for oxidizing LDL in atherosclerotic lesions. The binding of copper...
