Chinese medicine believes that cauliflower is sweet and flat, and has the effect of clearing heat and moistening the lungs. The high content of vitamin C has a strong scavenging effect of free radicals, especially on carcinogens - the formation of amine nitrite has a significant blocking effect. Cauliflower is rich in vitamin K, which can prevent the rupture of blood vessel walls due to high brittleness. The flavonoids contained in cauliflower can in turn reduce the incidence of cardiovascular disease. Studies have shown that cauliflower contains a substance called radish sulfide, has a strong anti-cancer effect, especially on breast cancer, rectal cancer, stomach cancer and other preventive effects. The content of this substance in broccoli is even higher. Scientists have extracted this substance from broccoli for cancer prevention and adjuvant therapy. In addition, broccoli also has the effect of killing Helicobacter pylori, which causes stomach cancer. So as far as nutrition is concerned, it's still better to have broccoli.
