Is there a Vitamin K difference between hot-house and home-grown tomatoes?
My father has been on Coumadin for 4 weeks and his doctor
told him he could not eat home-grown garden tomatoes - just hot-house
tomatoes! From viewing your website, the tomato is low in vitamin
K, so what is the deal?
Dr. Gourmet Says...
I must admit that I very much enjoyed your
question. My first reaction was that tomatoes are tomatoes but when
answering Ask Dr. Gourmet questions I always want to make sure that the
reply is correct. As I wasn't 100% certain that a tomato is a tomato
when it comes to Vitamin K content, I consulted some experts at the USDA.
I was referred to Dr. Sarah L. Booth who is the Director of the
Vitamin K Laboratory at the Jean Mayer USDA Human Nutrition Research
Center on Aging at Tufts University. She very graciously replied to your
question. Here is her answer:
From the standpoint of vitamin K, I cannot point to any data
that would support the recommendation to avoid home grown tomatoes.
Tomatoes have very little variation in terms of vitamin K, so I would
recommend eating tomatoes regardless of their source.
A four ounce tomato has about 9 micrograms of Vitamin K
which is considered a low amount. As Dr. Booth says, there's no reason
that your father's homegrown tomatoes would be higher in Vitamin K.
