Be sceptical, ask questions, demand proof. Demand evidence. Don't take anything for granted. But here's the thing: When you get proof, you need to accept the proof. And we're not that good at doing that.
All the food we eat - every grain of rice and kernel of corn - has been genetically modified. None of it was here before mankind learned to cultivate crops. The question isnt whether our food has been modified, but how.
People wrap themselves in their beliefs. And they do it in such a way that you can't set them free. Not even the truth will set them free.
Your dollar cheeseburger isn't a dollar if you factor in what it's going to cost in health care.
I understand the horrors of having no insurance, but, believe me, eight hours of sleep and good meals are NOT going to prevent you from getting sick. Don't gamble with your life; it's a stupid bet.
Vaccination is a public health issue because influenza is a highly contagious disease. If you don't vaccinate your child, his or her schoolmates are much more likely to become ill. That is why some places (New York, for example) are making the vaccine mandatory for school children.

In the Internet age, with the screaming on the radio, etc., it is hard to know what to believe and who is informed and who is not.
I think it's too soon to say that, and I think, basically - most of the people that I ran across and most of the studies that I saw suggest people don't go to McDonald's to eat healthy food. They go to eat fries and cheeseburgers.
I think it is true that you can eat extremely healthy food at McDonald's, and you can eat amazingly badly at Chipotle.
Daily vitamins are of no value.
Flu is easily transmitted, so if you are working with sick people - who are most at risk for getting seriously ill - you ought to be vaccinated. I am not really equipped to say whether it should be the law or not.
I started to write about science and medicine at the Washington Post, in the early days of the AIDS epidemic.
I have never earned one penny from any pharmaceutical company. I will never accept one penny from them either. Ever.
It is not possible to assert publicly that Monsanto is anything other than venal without being accused of being a sellout, a fraud, or worse.
There are always potential side effects for every vaccine.
