Yacon (Smallanthus sonchifolius) as a Food Supplement: Health-Promoting Benefits of Fructooligosaccharides
Yacon (Smallanthus sonchifolius), a perennial plant of the family Asteraceae native to the Andean regions of South America, is an abundant source of fructooligosaccharides (FOS). This comprehensive review of the literature addressed the role of yacon supplementation in promoting health and reducing the risk of chronic diseases. According to several preclinical and clinical trials, FOS intake favors the growth of health-promoting bacteria while reducing pathogenic bacteria popul...

Vitamin D Status and Supplementation Practices in Elite Irish Athletes: An Update from 2010/2011
Vitamin D deficiency is a global health concern that is prevalent in Ireland. The vitamin D status of elite Irish athletes following implementation of a revised supplementation policy in 2010/2011 has not been explored to date. This study aimed to assess the vitamin D status of elite Irish athletes participating in high-profile sports and establish if equatorial travel, supplementation and/or sunbed use predict vitamin D status. Across Ireland, blood samples (n = 92) were obtained from ...

The Regulation of Innate Immunity by Nutritional Factors
Recent years have witnessed growing interest in the biochemistry
and physiology of nutrients for mammals, such as amino acids, fatty acids, polyphenols, and oligosaccharide.
Notably, dietary nutrients have critical importance on immune function, especially in the pathogenesis of many immune related diseases including autoimmune diseases, inflammatory bowel disease (IBD), and cancer.These studies propose the way to manipulate immune associated diseases
with a nutritional aspect.

The pleiotropic role of vitamin A in regulating mucosal immunity
The effect of vitamin A on mucosal immunity has never been subjected to extensive studies until recently. We started to work in this area in
the early 1970s when we observed that children with protein-calorie malnutrition (PCM) often had defective mucosal immunity, judging from
the incidence of respiratory tract infections and diarrhea. We reported that these children had depressed secretory IgA (sIgA) levels in their
nasal wash fluids. The IgA level in specimens collected from those superimposed with some degrees ...

The Association of Vitamin D Status with
Dyslipidaemia and Biomarkers of Endothelial Cell Activation in Older Australians
Background/Aims: Vitamin D has been investigated for many non-skeletal effects. The objective of this study was to determine whether circulating lipids, systemic inflammation, and biomarkers of endothelial cell activation varied with the vitamin D status of older Australians. Methods:
One hundred and one participants were proportionately and randomly sampled across tertiles of 25 hydroxy vitamin D (25(OH)D) from a larger cohort of free living older adults (T1 median ...

Green tea consumption and cause-specific mortality: Results from two prospective cohort studies in China
Green tea is one of the most widely consumed beverages in Asia. While a possible protective role of green tea against various chronic diseases has been suggested in experimental studies, evidence from human studies remains controversial. Methods: We conducted this study using data from Shanghai Men's Health Study (SMHS) and Shanghai Women's Health Study (SWHS), two population-based prospective cohorts of middle-aged and elderly Chinese adults in urban Shanghai, China. Hazard ratios ...

White tea (Camellia sinensis) inhibits proliferation of the colon cancer cell
line, HT-29, activates caspases and protects DNA of normal cells against
oxidative damage
Tea (Camellia sinensis) is one of the most consumed beverages in the world. White tea is made from the buds and young leaves of the tea plant which are steamed and dried, whilst undergoing minimal oxidation. The MTT assay was used to test the extract on the effect of the proliferation of the colorectal cancer cell line, HT-29. The extract inhibited the proliferation of HT-29 cells with an IC50 of 87 lg/ml. The
extract ...
