Which boil water has the highest cancer risk?
When it comes to cancer, the results depend on a number of factors.
Some studies show that boiled water contains less carcinogenic compounds, while others suggest that the boiled water could also lower the risk of colon cancer, thyroid cancer and prostate cancer.
But how effective are the boiled eggs?
Researchers from the University of Pennsylvania and the University at Buffalo looked at more than 2,400 people who had never used boiled eggs and compared them with a control group of similar-aged women.
The results showed that the egg group had a 50 per cent lower risk of developing colon cancer.
The researchers said that the results suggested that boiled eggs were not a panacea for cancer.
“In general, the findings are consistent with those from other studies,” they wrote in the journal Cancer Prevention Research.
“Boiled eggs appear to have a low level of carcinogenic and mutagenic activity compared to a control diet.”
A similar study in the UK in 2016 found that boiled potatoes had similar cancer-causing potential to boiled eggs, but found that it was not more carcinogenic.
“Potatoes are rich in iron and zinc, which are known to increase the risk for cancer,” Dr. Sarah A. Miller, a professor of epidemiology at the University College London, told Reuters Health.
“There’s a lot of evidence that the potato’s high iron content is also associated with increased risk of cancer, which suggests that it may be more effective than boiled eggs for reducing the risk.”
A review published in Cancer Prevention in 2016 also found that the amount of iron in boiled potatoes is similar to that in boiled eggs.
But there was no evidence that boiled egg consumption reduced the risk.
What’s more, a 2013 review published by the International Agency for Research on Cancer found that “cooked potatoes, when consumed with eggs, can increase cancer risk and, in particular, the risk in those with prostate cancer.”
“These results may be related to the high level of iron content in boiled potato, which may contribute to the risk increase,” Miller said.
“Potatoes, however, are rich source of vitamins and minerals that are important in maintaining normal liver function, including vitamin B12, folate, iron and vitamin K. This may also help protect against cancer.”
