The new data, published in the Journal of Nutritional Biochemistry, tested the potential for anthocyanin-containing purple potatoes to block the growth of cancer tumours, even when they have been cooked – after previous research suggested that the polyphenols found in purple potatoes (PP) may help to battle cancer. Led by Venkata Charepalli from Pennsylvania State University, the team used laboratory tests including in vitro cell line investigations and animal modelling to test how PP impacted colon cancer growth, and in particular, colon cancer stem cells (CSCs), which have previously been suggested to be target by dietary bioactives such as curcumin. The team reported that their data from in vitro and mouse models suggests that baked purple-fleshed potatoes suppressed the growth of colon cancer tumours by targeting the cancer’s stem cells. They added that there may be several substances in purple potatoes that work simultaneously, and on multiple pathways, to help kill the colon cancer stem cells, including anthocyanins and chlorogenic acid, and resistant starch. “Our earlier work and other research studies suggest that potatoes, including purple potatoes, contain resistant starch, which serves as a food for the gut bacteria, that the bacteria can covert to beneficial short-chain fatty acids such as butyric acid,” said study senior author Professor Jairam Vanamal – also of Penn State. “The butyric acid regulates immune function in the gut, suppresses chronic inflammation and may also help to cause cancer cells to self-destruct.” Boosting physical activity and curbing sitting time are highly likely to lower breast cancer riskBreast Cancer Association Consortium (UK), September 6, 2022Boosting physical activity levels and curbing sitting time are highly likely to lower breast cancer risk, finds research designed to strengthen proof of causation and published online in the British Journal of Sports Medicine. The findings were generally consistent across all types and stages of the disease, reveals the Mendelian randomization study, prompting the researchers to recommend a stronger focus on exercise as a way of warding off breast cancer. Mendelian randomization is a technique that uses genetic variants as proxies for a particular risk factor—in this case lifelong physical activity levels/sedentary behavior—to obtain genetic evidence in support of a causal relationship. Observational studies show that physical inactivity and sedentary behavior are linked to higher breast cancer risk, but proving they cause breast cancer is another matter. The researchers included data from 130,957 women of European ancestry: 69, 838 of them had tumors that had spread locally (invasive); 6667 had tumors that hadn’t yet done so (in situ); and a comparison group of 54,452 women didn’t have breast cancer. Researchers estimated overall breast cancer risk, according to whether the women had or hadn’t gone through the menopause; and by cancer type (positive for estrogen or progesterone, or HER-2, or positive/negative for all 3 hormones), stage (size and extent of tumor spread), and grade (degree of tumor cell abnormality). These case-control groups comprised: 23,999 pre/peri-menopausal women with invasive breast cancer and 17,686 women without; 45,839 postmenopausal women with breast cancer and 36,766 without. Analysis of the data showed that a higher overall level of genetically predicted physical activity w
