Dear Mr. Pruitt,
First let me introduce myself. My name is Dr. E.A. Thackaberry, and I am your boss. Actually, I’m your boss’ boss, since the President of the United States technically works for me and the other American citizens. I am writing this letter to you because it seems you have failed to grasp some basic scientific concepts which are critical for your new job as head of the Environmental Protection Agency. As your boss, I want to help you, because I want you to succeed in your new role.
There are a whole lot of people on statins these days. Statins are a class of drugs intended to lower your LDL (the so-called “bad” cholesterol), leading to a reduction in heart disease risk. This is great, but many patients are surprised to learn that they have to avoid grapefruits and grapefruit juice while taking statins, and since statins are generally taken daily for long periods of time, this can essentially mean no more grapefruit products for many people.
What do doctors have against grapefruits? Do people really need to avoid them completely? Aren’t apples supposed to keep doctors away? UseYourBrain has the answers.

The Bad Science: St. John’s Wort as a treatment for Depression
What do they claim? Suggested uses include the treatment of depression, anxiety, boosting the immune system to fight infections, among many other potential indications
Are they trying to sell you something? A bottle of supplements will cost you about ten dollars.
Is any of this true? St. John’s Wort is an extract of Hypericum perforatum. A typical extract contains over 150 different chemicals isolated from the plant, most of which aren’t known to do anything for humans. Any potential activity of this extract is believed to come from a few classes of compounds (the naphthodianthrones, the phloroglucinols, and the chemical hypericin) which make up a very small percent of the total dose of the extract. St John’s Wort has a long history of use as an herbal remedy, mainly for depression and anxiety. There is ample literature demonstrating some degree of anti-depressive and anti-inflammatory actions. For depression, the evidence is spotty – some studies have shown benefit, while others have shown none or less than standard anti-depressant drugs. In truth, St. John’s Wort might have had a future as a first line option for mild forms of depression had it not been for…
Is any of this dangerous? This is where things get tricky.
You’ve probably heard the statistic before. 97% percent of scientists agree that global warming is real. People throw this number around, but where did it come from, and what exactly does it mean? Here at UseYourBrainForScience.com, we’re all about facts (though apparently not about brevity in our blog name), so here’s the skinny on this often misquoted number.
First, the statement above is wrong.

The Bad Science: Ozone Therapy
What do they claim? Suggested uses include treatment for all types of infectious diseases, arthritis, Alzheimer’s, cancer, and numerous other conditions
Are they trying to sell you something? Yup, you need a special machine to generate the ozone and the “treatments” will cost $100-$150 per session. Multiple sessions are generally recommended.
Is any of this true? Surprisingly, ozone therapy has been studied in some medical settings.
