Jayne Hurley, senior nutritionist at the Center for Science in the Public Interest, reminds us that people on blood thinners don't need to avoid greens, they need to avoid big swings in the amount of greens -- and vitamin K -- they have from one day to the next. That's what could cause a problem.
"If you're eating just a spinach or green leafy salad with your lunch or dinner, your doctor can easily adjust your dose of medicine to account for the extra vitamin K," Hurley said. "That shouldn't be a reason not to eat your greens."
The important thing is to build those leafy greens into your medical plan. If you're on a blood thinner and want to add more greens to your diet, talk to your doctor first.
Hurley reminds us that leafy greens are a good source of magnesium, lutein – which is good for your eyes – as well as fiber and folate.
By the way, the top 5 veggies with Vitamin K are Kale, Spinach, collard greens, turnip greens and Swiss chard.
