Potatoes are the fourth most plentiful food crop in the world, yet the scientific literature on the health effects of potato consumption is scarce. This study aimed to investigate the association between potato consumption and the risk of colorectal cancer (CRC) among 79,778 women aged 41-70, in the

OBJECTIVE To investigate the effects of proteins purified from sweet potato storage roots on human colorectal cancer cell lines. METHODS 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, Hoechst 33258 nuclear staining and Boyden transwell chamber methods were used to

METHODS Anthocyanins, the natural pigments in plant foods, have been associated with cancer prevention. However, the content of anthocyanins in staple foods is typically low and the mechanisms by which they exert anticancer activity is not yet fully defined. RESULTS We selected an

Purple-fleshed sweet potato P40 has been shown to prevent colorectal cancer in a murine model. This study is to identify anthocyanins by using HPLC/MS-MS and assess the stability during various cooking conditions. P40 possesses a high content of anthocyanins up to 14 mg/g dry matter. Total 12

A new small molecule glycoprotein SPG-8700 with potential anti-colorectal cancer activity was firstly separated by tracking of bioactivity from a new sweet potato variety Zhongshu-1. Matrix-assisted laser desorption ionization mass spectrometry, high-performance liquid chromatography and amino acid

A case-control study has been conducted to investigate the relationship between lifestyle and risk of colorectal cancer. Cases are one hundred patients diagnosed with colon and rectal cancer in Tokai University Hospital between 1986 and 1994. Three controls per case were individually matched by age,

BACKGROUND Although diet has long been suspected as an etiological factor for colorectal cancer, studies of single foods and nutrients have provided inconsistent results. OBJECTIVE We used factor analysis methods to study associations between dietary patterns and colorectal cancer in middle-aged

BACKGROUND Anthocyanin-rich foods and preparations have been reported to reduce the risk of life-style related diseases, including cancer. The SL222 sweet potato, a purple-fleshed cultivar developed in New Zealand, accumulates high levels of anthocyanins in its storage root. METHODS We examined the

OBJECTIVE Starch that escapes digestion in the small intestine (resistant starch [RS]) may act similarly to nonstarch polysaccharides in the colon. The aim of this study was to examine the effect of raw potato starch alone and in combination with wheat bran on tumor development and precancer events

Studies have shown that different kinds of carbohydrates are able to modify the development of colo-rectal cancer in animals as well as humans. In the present study with rats sucrose and two types of starches were investigated for their effects on the development of aberrant crypt foci (ACF), which

BACKGROUND The development of certain biologic characteristics in human colorectal tumor xenografted onto nude mice are described with respect to their precocious passages, i.e., passaging below 10 onto athymic mice. METHODS The biologic characteristic monitoring involved the determination of

Background: The effects of consuming fast foods, sweets and beverages on the development of colorectal cancer (CRC) are unclear. The aim of this case-control study was to assess possible associations between the consumption of different fast foods, sweets and beverages and CRC risk in a Jordanian

Hereditary forms of colorectal cancer account for less than 5 % of colorectal cancer but attract disproportionate attention because they offer an opportunity for effective surgical prophylaxis, influence the health of the wider family and give insight into the critical pathways of carcinogenesis.

Sweet potato leaves contain the highest levels of functional polyphenols. In this study the effects of the sweet potato leaf extract and its contents, such as mono (3, 4, and 5)-caffeoylquinic acid (CQA), di-CQA (4,5-diCQA, 3,5-diCQA, and 3,4-diCQA) and caffeic acid (CA), were evaluated on the
