If you believe everything you read on the Internet, then is seems that a chemical found in thousands of products is causing an epidemic of severe neurological and systemic diseases, like multiple sclerosis and lupus. The FDA, the companies that make the product, and the “medical industrial complex” all know about the dangers of this chemical, but are hiding the truth from the public in order to protect corporate profits and avoid the pesky paper work that would accompany the truth being revealed.
The only glimmer of hope is a dedicated band of bloggers and anonymous email chain letter authors who aren’t afraid to speak the truth. Armed with the latest anecdotal evidence, unverified speculation, and scientifically implausible claims, they have been tirelessly ranting about the evils of this chemical for years. Undeterred by the countless published studies manufactured by the food cartel that show this chemical is safe, they continue to protect the public by spreading baseless fear and hysteria.
Hopefully, you don’t believe everything you read on the Internet, and you don’t get your science news from email SPAM, where the above scenario is a common theme. While there are many manifestations of this type of urban legend, I am speaking specifically about aspartame — an artificial sweetener used since the early 1980s. The notion that aspartame is unsafe has been circulating almost since it first appeared, and like rumors and misinformation have a tendency to do, fears surrounding aspartame have taken on a life of their own.

(Guest post submitted by MD Anderson Cancer Center)
Aisles in grocery stores and pharmacies are stacked with vitamins, minerals, herbs or other plants that you take in pill, capsule, tablet or liquid form. And, many of us buy these supplements and take them regularly, hoping to lower our chances of getting cancer and other diseases.
But do supplements really work wonders? Should you take them to help prevent cancer? Our experts say beware.
“Don’t be fooled by the label on the bottle,” says Sally Scroggs, health education manager at MD Anderson’s Cancer Prevention Center. “Researchers are still unsure about whether or not supplements actually prevent cancer.” Some studies have suggested that supplements may actually increase cancer risk by tilting the balance of nutrients in the body.

I’m only a monthly contributor here, but between being a Science Based Medicine (SBM) reader and having my own blogs, I often grow weary of the blind criticism that researchers and drug companies couldn’t care less about traditional folk medicines as drug products. My laboratory spends every single day working on natural product extracts in the search for compounds that may have selective effectiveness against cancer. So this is a bit of a sore spot for me.
Two [recent] papers from Cancer Prevention Research on the potential anticancer effects of a diabetes drug (see Nathan Seppa’s story here) remind me to tell the story of a Middle Ages European herbal medicine used to treat polyuria that gave rise to one of the most widely prescribed drugs in the world, metformin (Glucophage in the U.S.). Metformin, known chemically as a biguanide, dimethylguanide to be precise, traces its roots to the plant Galega officinalis. Known as goat’s rue, French lilac, or professor weed, this plant was shown to be a rich source of guanidine and a less toxic compound later called galegin or galegine (isoamyline guanidine).

This is a thoughtful “sounding board” piece in the New England Journal of Medicine this week: Lessons from the Mammography Wars.
It is so important to keep this discussion alive. The miscommunication that took place last November of what the U.S. Preventive Services Task Force tried to convey, and the complicity of some news organizations in adding to that confusion, provide lessons from which we simply must learn to do better.

The Telegraph reports that the number of screening pap smears performed in the UK has declined after an 8 percent blip upwards in 2009 when publicity surrounding the death of Jade Goody from cervical cancer may have led more women to have this important screening test:
NHS laboratories processed 415,497 tests in 2009-2010, about 35,000 fewer than the previous year when 450,522. Miss Goody’s death in March last year prompted a 20 percent increase in the number of Scottish women taking tests. More than 122,000 were processed between April and June last year, the statistics revealed.
The irony of course, is that British reality TV star Jade Goody did have pap smears, but chose to ignore her doctor’s recommendations for treatment when her pap smears came back abnormal.
Nonetheless, the decline in pap smears has led NHS of Scotland to initiate a campaign to reach the up to 25 percent of young women who do not respond to invitations to have pap smears. Read more »
