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, tomato is low in vitamin K, so what is the deal?
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.
Thanks for your very interesting question.
