Eating broccoli, Brussels sprouts and cabbage is good for your health, science is amply proving this. The vegetables of the Cruciferae family, in fact, bring valuable antioxidant substances useful against tumors. But that's not all, in fact, as a very recent scientific research appeared in the British Journal of Nutrition thanks to the work of a team from ECU's School of Medical and Health Sciences and the University of Western Australia (Blekkenhorst et al, British Journal of Nutrition, July 2020), broccoli and Brussels sprouts are also capable of protecting blood vessels and heart health.
Blood vessels can, in the long run, undergo diseases and disorders, such as their narrowing due to calcium build-up. When this happens, the blood vessels stiffen, circulating blood flow decreases, and the risk of heart attack and stroke increases. Based on previous studies, scientists had already observed that people who consumed more vegetables belonging to the cruciferous family, namely broccoli, Brussels sprouts and cabbage, also had a lower incidence of cardiovascular disease. However, the protective mechanisms had not been understood until now. In the study under review, the scientists drew on analyses performed on 684 women, recruited for an earlier 1998 study. What emerged was that women who ate more crucifers, namely more than 45 grams per day each day, had a 46% lower chance of having calcium deposits in the aorta than women who consumed less or not at all crucifers. The researchers explained this observation by the fact that cruciferous plants contain vitamin K, capable of inhibiting the calcification of the blood vessel walls.
Scientists therefore encourage people to include cabbage, broccoli and Brussels sprouts in their diet. But be careful, as pointed out by the authors of the study themselves, we must not fall into the error of eating only crucifers. For health it is important to ensure a varied diet and different types of fruit and vegetables.
