One of the major causes of cancer is active oxygen which oxidizes the normal cells, transforming them into cancer cells. The substance that suppresses the occurrence of active oxygen is beta-carotene which is rich in carrots.
But there is another substance which suppresses the occurrence of active oxygen more than 2 times of beta-carotene. That is beta-cryptoxanthin. In the people who took a lot of beta cryptoxanthin, the ratio that lung cancer and cervical cancer occur decreased by 60 % and esophageal cancer decreased by 80 %. Citrus Unshu in Japan which is the same species (mandarin orange) and similar to clementine coantains 60 times more beta-cryptoxanthin than orange. Eating 1 to 2 citrus Unshu is good to prevent cancer. The thick outside skin contains a lot of beta-cryptoxanthin which suppresses active oxygen and is also rich in limonene which suppresses carcinogenic substance. The skin is good to eat drying it. The skin is used as Chinese herbs. It is recommended to eat one teaspoon a day adding it to tea, yogurt or soup.
