Confused. does eating broccoli & fish nuggets daily thin blood? i thought vitamin k thickened blood?

That's silly: Food choices have essentially no effect on coagulation parameters. A few vitamin-K-rich foods should be avoided if you are taking coumarin as an anticoagulant. Beyond this, ignore all "pop" advice about food choices -- they're entertainment at best, disinformation by people posing as your friends at worst. Your physician or a registered dietician are more reliable.
