Can Vitamin E Reduce the Risk of Liver Cancer?
By David Morris
The JOURNAL OF NATIONAL CANCER INSTITUTE has published a study indicating that Vitamin E may help lower the risk of liver cancer. As an antioxidant Vitamin E can help reverse or prevent damage to DNA caused by cancer-creating 'free radicals". Vitamin E is sourced in many foods, and superfoods such as spirulina, chlorella, bee pollen and barley grass powder which are especially rich sources.
While not as common as breast or lung cancer, liver cancer is still a major killer worldwide.
Some of the main risk factors are:
Chronic infections, such as hepatitis B or C, is the main and most significant risk factor for cancer of the liver.
Curiously, men are more likely to develop liver cancer than women.
Ethnic groups: Pacific Islanders and Asians suffer the biggest rates of liver cancer.
Alcohol abuse which may cause cirrhosis of the liver, is another significant risk factor for liver cancer.
Lessening the risks
Researchers from the Shanghai Cancer Institute, China, investigated the effects vitamin C, vitamin E, and multivitamins had on liver cancer risk. The study involved 132,837 people, the women as part of the Shanghai Women's Health Study lasting 11 years, and men as part of the Shanghai Men's Health Study, which lasted for 6 years.
Researchers found that:
During the follow-up period, 267 people developed liver cancer.
The higher vitamin E intake either from diet, and or supplements, was correlated with a significantly lower risk of liver cancer in both men and women.
Multivitamin supplements and Vitamin C, were linked to a higher risk of liver cancer in people with liver disease, or liver cancer in the family. However, Vitamin C and other vitamins from dietary sources (ie. directly from food) did not appear to influence the chances of liver cancer.
"We found a clear, inverse dose-response relation between Vitamin E intake and liver cancer risk", the authors said.
Vitamin E is an antioxidant, which boosts the immune system, protecting and repairing DNA from free radical damage. As well as fresh, green leafy vegetables, many super foods are naturally high in vitamin E, including spirulina, bee pollen, chlorella and barley grass powder
Need for further research
The findings of this new study published recently in 2012 are encouraging, and they need to be duplicated in further ongoing controlled clinical trials. As this was an 'observational study', the researchers were relying on the participants own subjective reporting of their dietary and supplement intakes, to elicit their conclusions. Results and conclusions made from these types of observational studies are less reliable and strong compared to controlled trials.
