- According to the High Health Service, 66,000 elderly people in France suffer hip fractures every year.
- 10-30% of them become addicted within a year of the fracture.
- Falls and osteoporosis are major risk factors for hip fractures.
The older, the less in autumn is banal. The risk of fractures increases with age, sometimes requiring hospitalization. Some people may be more affected due to their medical history, illness, alcohol consumption or lack of physical activity. Conversely, however, others seem more risk-averse fracture related to falling. According to a study published in a specialized journal Food and functiondiet contributes to good bone health and can therefore reduce this risk.
A study on the relationship between vitamin K1 and fracture risk
This work by Australian researchers is based on the participation of 1,400 women over the age of 70. They were followed for more than 14 years to monitor the risk of hip fracture and hospitalization. During this time, they regularly answered questionnaires about themselves to feed. Scientists were especially interested in their quantity vitamin K1 consumed by participants. This nutrient is especially abundant in kale, spinach, broccoli, seaweed, fennel, castor oil, soybean or canola oil.
Hip fracture: K1 halves the risk of hospitalization
The results of this study show that women who consumed more than 100 micrograms of vitamin K1 daily, which is about 125 grams of leafy vegetables, had a 31% lower risk of developing the disease. fracture, compared to participants who consumed less than 60 micrograms per day. When it comes to hip fracture hospitalizations, women consume the most vitamin K1 the risk was halved. “Our results were independent of many established fracture risk factors, including body mass index, calcium intake, vitamin D levels, and disease.Dr. Marc Sim, lead author of the study, explains.
How to explain the protective effect of vitamin K1 against fracture risk?
This scientist, whose work is particularly focused on the influence of nutrition on the functions of the musculoskeletal system, reminds us that this vitamin is also associated with better cardiovascular health. In the case of bone function, the benefits of vitamin K1 may be related to its effect on the secretion of osteocalcin, these proteins are part of bone components and are involved in calcium fixation. According to the author, medical studies have shown that intakes of vitamin K1 below 100 micrograms per day may be too low to carry out this process. “Vitamin K1 may also promote bone health by inhibiting various substances in bone resorption., he says. To get the most benefit from this nutrient, he recommends consuming at least 100 grams of vitamin K1 daily.equal to one or two servings of vegetables such as spinach, kale, broccoli and kale“.
