In winter, the majority of vegetables belong to the cruciferous family. The main winter vegetables of the crucifer family are; broccoli, brussels sprouts, cabbage, cauliflower, radish and cress. They are generally rich in folic acid (vitamin B9), vitamin C, selenium, potassium and fiber. They contain a natural compound called "glycosinolate" which protects against many types of cancer. Indole-3-carbinol, another substance in the content of these vegetables, also breaks down the excess estrogen. Therefore, it is thought to be effective in hormone sensitive cancer types.
Green leafy winter vegetables contain high amounts of vitamin K and therefore have an important role in blood clotting. However, if a strong blood thinner is used, it should not be consumed more than 2-3 times a week or should be further restricted if necessary. Vegetables in general have high potassium content and show a blood pressure balancing feature. If there is excess potassium in the blood, it should be used with caution.
Vegetables can be consumed on an average of 5 spoons in the main course by cooking with olive oil. If they are preferred to be boiled, they can be added to salads in smaller portions and optionally flavored with olive oil.
