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 ...

The safety of green tea extract supplementation in postmenopausal women at risk for breast cancer: results of the Minnesota Green Tea Trial
Green tea is one of the world’s most popular beverages and has been associated with a number of health benefits, including prevention of obesity (Huang et al. 2014), cardiovascular disease (Hodgson and Croft 2010), neurodegenerative diseases (Andrade and Assuncao 2012), and several site-specific cancers, including breast cancer (Yuan 2013). These beneficial effects are primarily attributed to the chemical properties of tea catechins, of which (-)-epi...

The Natural Polyphenol Epigallocatechin Gallate Protects Intervertebral Disc Cells from Oxidative Stress
Oxidative stress-related phenotypic changes and a decline in the number of viable cells are crucial contributors to intervertebral
disc degeneration. The polyphenol epigallocatechin 3-gallate (EGCG) can interfere with painful disc degeneration by reducing
inflammation, catabolism, and pain. In this study, we hypothesized that EGCG furthermore protects against senescence and/or cell
death, induced by oxidative stress. Sublethal and lethal oxidative stress were induced in primary human ...
