Low lacto fermented milk may reduce risk of colon cancer, but researchers say that the health effects are unknown.
“This is the first large-scale study of the potential health effects for lacto‐fermented foods in relation to colon cancer risk,” said study author Dr David Kornfield, a professor of epidemiology at the University of Sydney’s School of Public Health.
Dr Kornfields team also discovered that a study published in January 2015 in the Journal of Clinical Endocrinology and Metabolism found that low-fat milk was linked to lower rates of colon and rectal cancer in women, but that this was not a strong association.
The study authors concluded that milk may be a source of colorectal cancer risk because of its high milk fat content and the fact that high milk intake was associated with increased risk of colontams.
In contrast, Dr Kornstfield said he had “a couple of concerns” about the research.
He said it had not been conducted in large populations and that a large study would be necessary to understand the association between low-fiber dairy products and colon cancer.
“It is not clear if the milk product intake associated with coloreptal cancer is different from that associated with other types of cancer,” he said.
“One possibility is that lacto‑fermented products may act as protective factors, but this may be because of the high fat content in dairy products.”
Lacto‑fiber is a dairy product and there is evidence that high fat intake may be protective against colorerectal cancer, particularly if consumed with a low-energy diet.
“Dr Kowalewski added that there was a need for more research to clarify the association.”
There are some studies that show that there is a protective effect from lactofermented food, but the extent to which this effect may be due to milk fat is not known,” he added.”
The effect of milk on colorecolontams is not well understood, and the mechanisms by which lacto fibre may act are unknown.
“Dr Waiqiang Wang, from the School of Epidemiology at The Australian National University, said the results of the study were interesting, but not definitive.”
I think it’s important to take this into account when making dietary choices for people with a family history of colposcopy,” he told news.com.au.”
We need to have a better understanding of the mechanisms that affect colposcoepidemiology and therefore we need to take it into account before making recommendations for individuals.
