Norovirus has hit the U.S. hard and early this winter. It's not enough to simply stay away from people who are sick. There are innocent-looking, healthy evil-doers out there whose bodies are secret virus factories, and they are just as "happy" to give it to you as the guy with his head in the toilet.
Just like every winter, norovirus is going around like crazy. Some of you will get it and some of you won't. Is it simply luck, or is there something more going on? Yes, there is. If you have the "right" blood type you will probably be spared. But if you have the "wrong" type you may be hugging the bowl.
Does your blood type – specifically, your Rh factor (positive or negative) – matter in your daily life? Not in the slightest. But when pregnant your Rh status can matter, especially if it's negative.
In 1996 naturopathic physician Peter D Adamo published his Eat Right for Your Type diet book, claiming that people with different blood types should eat differently to preserve health and lose weight. The diet is based on the theory that different human blood types evolved at different times in our history, and therefore, we should be eating foods that were available to people at the period when each type first made its appearance.
