Grapes are not only a tasty and juicy berry, but also a powerful source of health healthy substances. One of them is vitamin K, playing an important role in blood coagulation and general health.

However, although most people can safely enjoy grapes, there is a certain category of people for whom its consumption may have serious consequences. Nutritionist Kelsi Lorenz explains Eatthis. com, why it is important to control vitamin K in the diet to those who take a medicine for liquefaction of blood.

In addition to numerous antioxidants and a certain amount of fiber, each berry contains one important element that you may not take into account: vitamin K. In total, one cup of grapes contains 22 ?g of this vitamin, which is about 24% of the recommended daily norm (RDA) for women and 18% for men.

For most people, increased consumption of vitamin K benefits. " Its deficiency can lead to easy occurrence of bruises or severe bleeding during cuts, since the body does not have enough vitamin for normal blood coagulation, ”explains the dietitian Kelsi Lorenz.

However, there is a group of people for whom caution should be taken with the amount of vitamin K in the diet. " Excessive or insufficient consumption of vitamin K during medication for liquefaction of blood can reduce their effectiveness or lead to serious problems, such as blood clots or excessive bleeding, ”Lorenz notes.

If you take drugs for liquefaction of blood, you do not need to panic or exclude grapes from the diet.

The nutritionist recommends focus on the table of products with high, medium and low vitamin K levels and try to maintain the same consumption from each category.

If grapes are regularly included in your diet - this is fine! But remember that for the effectiveness of drugs it is important to maintain stability in the consumption of this vitamin.

" If you plan to increase the consumption of products with vitamin K, for example, fresh spinach, be sure to discuss this with the doctor before increasing the dose and do the same when reducing consumption, ”Lauren notes.
