A new study by scientists from the Loma Linda University has revealed that vegetarians are at lower risk of developing colorectal cancer than non-vegetarians.

The study claimed that a vegetarian diet offers significant protection against cancers of the colon and rectum, which is the second-leading cause of cancer death in the United States after lung cancer.

The findings emerged from the university's multimillion-dollar Adventist Health Study-2 investigation that links diet to specific forms of cancer.

The study led by Dr. Michael Orlich, a specialist in family and preventative medicine, also claimed that pescovegetarians or vegetarians who eat fish had a 43% lower risk of colon or rectal cancer than non-vegetarians.

The new study was conducted on 135,095 randomly-selected adults from the US National Health Survey (2008-2011), out of which 19,299 of the participants were using psychedelic drugs. Clinical psychologists Teri Suzanne Krebs and Pål-Orjan Johansen from the Norwegian University of Science and Technology located in Trondheim analyzed the answers of the respondents.

The FDA has altered the label on the quit-smoking drug Chantix for creating awareness and address the concern over its potential to lower one’s tolerance level on alcohol and association with an annual risk of seizures.

The FDA warns, “Until patients know how Chantix affects their ability to tolerate alcohol, they should decrease the amount of alcohol they drink. Patients who have a seizure while taking Chantix should stop the medicine and seek medical attention immediately”.

The information provided by Chantix maker Pfizer and cases in the FDA Adverse Event Reporting System database served the basis of developing the new label.
