A new study published in Molecular Biology and Evolution suggests that consuming a long-term vegetarian diet may alter human DNA and make people more susceptible to some cancers and heart disease. This, according to researchers, is because DNA makes vegetarians more susceptible to inflammation by boosting arachidonic acid, a substance linked to cancer and inflammation. The study suggests that because of this, vegetarian populations have a 40% increased …
In Episode 75 David discusses the toxicity of Aluminum with Professor Chris Shaw, following on from the interview with Chris Exley in episode 71. Dr. Shaw started examining a degenerative neurological illness on Guam that his research indicated was caused by a combination of phytosterols in cycads and aluminum, and then went on to study Gulf War Syndrome, which he believed was at least partly due to the exposure to aluminum in over 20 vaccines given to soldiers in a short time. In 2013 he co-authored a paper that claimed a strong correlation between increased exposure to aluminum in vaccines and Autism Spectrum Disorder. But his major area of study is not epidemiology, but studies with mice, which have shown that injection of aluminum causes degeneration of the nervous system.
Chris also comments on the absolutism prevalent in mainstream discussions of vaccine safety, including the time when the Canadian public broadcaster, CBC, went after him, trying to get his management to criticize his research, something they refused to do, insisting that peer review of his grant applications and publications was sufficient, a major victory for academic and scientific freedom.
In 2013, I discussed several epidemiological studies providing good evidence of radiogenic risks at very low exposure levels. A powerful new study has been published in Lancet Haematology [1] which adds to this evidence. However the study’s findings are more important than the previous studies, for several reasons. First, it provides “strong evidence”, as stated by the authors, of a …
The year 2015 hasn’t been kind to Monsanto. In March, the World Health Organization declared that the company’s flagship product, its herbicide glyphosate or Roundup, is a probable human carcinogen. Increasingly, national health ministries are taking a hard second look at glyphosate’s health and environmental dangers and efforts are underway to ban the herbicide.[1] To protect its citizens, last year the Netherlands, Bermuda and Sri Lanka have either banned or imposed strict limits on Roundup. Last June, France banned its use in gardens. Brazil, Germany and Argentina are considering legislative bans. And this month, California’s environmental protection agency launched plans to label Roundup as a carcinogen.[2]
Glyphosate is the most widely used herbicide in the world today. Over 130 countries currently permit extensive use of the chemical. The US is the largest consumer, using approximately 20% of the world’s Roundup.[3] The latest reliable figures from the US Geological Survey record 280 million pounds of Roundup were used in 2012, nearly a pound for every American.[4] In 2013, gross profit of $371 million on crop chemicals including Roundup climbed 73% due to a 37% increase in sales. That same year Monsanto’s net income rose 22% to $1.48 billion.[5]
Air pollution exposure may be linked to a child’s risk of autism, a recent study suggests. The controversial findings echo similar results from a study last winter that found an increased risk of autism among children of women exposed to more smog late in pregnancy. This new study—which does not establish a direct connection between dirty air and autism—did not find …
