**5. Conclusion**

Cucumber is an excellent and unusual food. A cup of cucumber contained 16 calorie with its peel (15 without) and 4 percent of your daily potassium, 3 percent of your daily fiber and 4 percent of your daily vitamin C. Cucumbers also contained small amounts of vitamin K, vitamin C, magnesium, potassium, manganese and vitamin A among them Vitamin K is very important for bone health. Vitamin K intake reduces fracture rates, and combine work with vitamin D can increase bone density and positively affect calcium balance. Vitamin K helps in building bones and the effects seem to be important for women. Low vitamin K levels were associated with low bone density in women, but not in men. Low intakes of vitamin K were associated with an increased risk of hip fractures in middle-age women.
