Should i be avoiding foods rich in vitamin e and k?

Only if on coumadin (warfarin): I can't think of any reason for anyone to avoid foods rich in vitamin E (studies suggesting e is not safe used synthetic e- no evidence natural e is unsafe). Vitamin k is extremely beneficial but can interfere with coumadin (warfarin). But if on Coumadin (warfarin) you could still eat foods rich in vit. K & adjust dose accordingly. I do not like Coumadin (warfarin) partly because its effects on vit k- please see my comment.

Not necessarily: Good health requires small amounts of the fat-soluble vitamins a, d, e and k while larger amounts may be toxic. A diet rich in fruit, vegetables, whole grains and non-processed foods provides an adequate source of these and other vitamins. A reasonable level of sun exposure contributes to vitamin d formation.
