Blog entries from the web site of Linda Carney MD located at http://www.DrCarney.com.
Obviously, a blog about a house cat is hardly appropriate for a site dedicated to human health, but I feel that Callie's story is indeed significant to the human side of cancer. This post is Part 3 of Callie's Cancer blog that was posted on Monday, 22 August 2016 and of Part 2 that was posted on Wednesday, 25 Ja...
I followed Dr. Carney's blogs online for a long time before making my first appointment. Three years earlier I had become plant based due to a breast cancer diagnosis. That was an adjustment. I finally started to get into a groove with support groups and books I was reading but found myself disillusioned in a system that I did not want to be p...
Cancers are a deadly disease resulting annually in millions of deaths worldwide. In 2012, 8.2 million people were estimated to die from cancer globally, and more than half a million people were projected to die from cancer in 2016 in the United States. The fear of this deadly diagnosis influences many people to take me...
Effects of Beta-Carotene Supplements on Cancer Prevention: Meta-Analysis of Randomized Controlled Trials.
Non-smokers and smokers who take beta-carotene supplements are more prone to develop bladder cancer and all types of cancer respectively.
This study assessed the role beta-carotene supplements play in the prevention of cancer. Researchers systematically reviewed data obtained from 848 published articles and 6 randomized controlled trials.
The team of investigators discovered that beta-carotene supplement use was associated with high bladder cancer risk. In addition, regular intake of beta-carotene supplements was found marginally increased the odds of developing cancer among current smokers, but it had no effect on cancer prevention among non-smokers in this study. The results of this meta-analysis do not support the popular belief that frequent intake of antioxidant supplements, such as beta carotene supplements, may protect individuals against the development of various forms of cancer.
Effects of antioxidant supplements on cancer prevention: meta-analysis of randomized controlled trials.
The use of antioxidant supplements may increase an individual's chances of developing bladder cancer.
This study investigated the effect of antioxidant supplements on cancer risk. Researchers conducted a meticulous meta-analysis on data extracted from 31 published studies. They observed that the use of antioxidant supplements had no preventive effect on cancer development. According to this study, subjects on antioxidant supplements were found to have high bladder cancer risk. The findings of this meta-analysis reveal that frequent intake of antioxidant supplements may not exert a protective effect against cancer.
Individuals with high dietary intake of red and processed meats are susceptible to liver, colorectal, lung, and esophageal cancers.
This study was carried out to determine the association between dietary intake of unprocessed and processed red meat and the odds of developing cancer. Using validated food frequency questionnaires, researchers collated and examined data on the meat intake of 500,000 volunteers between the ages of 50-71 years recruited from the National Institutes of Health (NIH)-AARP (formerly the American Association for Retired Persons) Diet and Health Study Cohort. The cancer odds ratios of all the participants in this study were also evaluated.
Researchers observed that high consumption of both processed and unprocessed red meats increased the likelihood of developing lung and colorectal cancer. In addition, a surge in liver and esophageal cancer risk was linked to regular intake of unprocessed red meat in this study. The results of this study support the hypothesis that diets rich in red and processed meats may promote the development of cancerous cells in the colon, rectum, liver, lungs, and esophagus.
Association between dietary whole grain intake and risk of mortality: two large prospective studies in US men and women.
Generous consumption of whole grains may cut down all-cause mortality risk significantly in US men and women.
This study evaluated whole grain intake in relation to mortality risk in US men and women. Researchers tracked the whole grain consumption rates of 118,085 subjects recruited from the Nurse’s Health Study and the Health Professional’s Follow-up Study and monitored their mortality records. They observed that subjects on diets rich in whole grains had lower odds of dying from cancer, cardiovascular disease, and other causes. The findings of this study indicate that increased consumption of whole grains may help reduce total mortality risk.
