The Vitamin K is a water-soluble vitamin whose main function, which is also the one that gives it its scientific name, ie Koagulation Vitamins, Is to play an important haemostatic Vitamin E is also important for its help in the formation and maintenance of bone tissue.
The Vitamin K is found mainly in Green leafy vegetables Such as lettuce, spinach and broccoli, especially in the meat than beef, pork and dairy products, as well as being produced by synthesis by the intestinal microflora.
A recent study conducted by researchers Human Nutrition Universitat Rovira i Virgili Reus, Catalonia, Published at Journal of Bone and Joint Surgery, A high presence of Vitamin K deliver significant benefits to the bone the elderly Both men and women, and helps them to keep strong and intact.
The novelty of the Spanish research is that, for the first time, was taken into consideration the direct relationship between a large amount of vitamin K in the diet and changes in the internal structure of bone.
The study was conducted on a sample of 200 older adults with an average age of 67 years, who were given a questionnaire that they were following the diet and which foods to eat more frequently, monitor, then, for two years. The scientists used several tools to estimate the intake of vitamin K and various diagnostic techniques to measure the state of health bone and bone density, such as ultrasound at the heel.
The researchers were able to observe so that
any increase in the levels of 100 micrograms of vitamin K intake corresponded to an increase in bone density of 0.008 g/m2.
Also, the more the diet was rich in Vitamin K and the bones were more elastic and healthy and did not suffer from the phenomena of aging and micro porosity of osteoporotic fractures. The Vitamin K is so important for healthy bones because it activates osteocalcin, a protein that activates a synthesis that allows the calcium fixed in bone, without Vitamin K this protein is not activated and the bones are more fragile and susceptible to fractures.
