[prMac.com] Revere, Massachusetts - Independent developer James Hollender has released version 1.7 of Vitamin K, his app for iPhone, iPod touch and iPad. Vitamin K allows users to easily find out how much vitamin K there is in over 900 different food serving which is critical in helping keep the effectiveness of their blood thinning medications working properly. If you take blood thinning medications like Coumadin or Warfarin, then this is an app you will truly make use of on a regular basis.
New in version 1.7 is the capability to print the food serving information pages, and also the general information pages using AirPrint.
For those taking blood thinning medications like Coumadin(R) or Warfarin (also known as Jantoven, Marfarin, Lawarin, Waran and Marevan), then this is an app which will truly be used on a regular basis. Most lists providing information on the content of vitamin K in foods generally contain only a limited number of foods, and often they don't indicate the serving size. It is important to understand that the goal for those taking blood thinning medications isn't to not eat any foods with vitamin K, but rather to keep relatively constant the amount of vitamin K ingested each day so the amount of blood thinning medication prescribed can work effectively. This can be different for every person using these medications, and this is why doctors require occasional blood tests as they indicate if the dosage needs to be adjusted.
All too often it is heard that users of blood thinning medications should stay away from dark green leafy vegetables, but there are a host of other foods containing vitamin K. Even the dark green leafy vegetables contain varying amounts of vitamin K. Further, each food has its own characteristics and sometimes whether it is fresh, frozen or canned can make a difference in the vitamin K content. The important thing to understand is that too much may be inadvertently ingested because something which is thought to not contain any vitamin K when in fact it does. A good example would be carrots which contain varying amounts of vitamin K. A single baby carrot has only 0.9 mcg (very low) while a cup of canned carrot juice contains 36.6 mcg (high).
The Vitamin K app provides information about foods and how they are rated for Vitamin K content based on preparation and serving sizes. This is provided as a means to assist in deciding which foods to eat if you are using blood thinning medications such as Coumadin(R) or Warfarin. The foods are rated from EXTREMELY LOW to EXTREMELY HIGH in Vitamin K. The following colors help readily identify which is which:
* Black = Rated EXTREMELY HIGH in Vitamin K (700.0 - 1146.6 mcg)
* Dark Red = Rated VERY HIGH in Vitamin K (300.0 - 699.9 mcg)
* Red = Rated HIGH in Vitamin K (25.0 - 299.9 mcg)
* Orange = Rated MODERATELY HIGH in Vitamin K (20.0 - 24.9 mcg)
* Yellow = Rated MODERATE in Vitamin K (15.0 - 19.9 mcg)
* Light Green = Rated MODERATELY LOW in Vitamin K (10.0 - 14.9 mcg)
* Green = Rated LOW in Vitamin K (5.0 - 9.9 mcg)
* Cyan = Rated VERY LOW in Vitamin K (0.1 - 4.9 mcg)
* White = Rated EXTREMELY LOW in Vitamin K (less than 0.1 mcg)
There are eight tables listing foods:
* All Foods
