The Japan Agricultural News recently reported: Eating citrus fruits can have anti-cancer effects, and the sweeter they are, the better the anti-cancer effect. According to research, the reason citrus fruits can fight cancer is that they contain a large amount of β-cryptoxanthin. The anti-cancer effect of β-cryptoxanthin in citrus fruits is five times stronger than that of β-carotene found in carrots. Additionally, naringin, found in the peels of oranges and grapefruits, also has excellent anti-cancer effects.
Scientists have also found that the higher the sugar content of citrus fruits, the more β-cryptoxanthin they contain, and thus the better their anti-cancer effect. Moreover, the content of β-cryptoxanthin in citrus fruits does not change after drying and storage. An ordinary person can achieve good anti-cancer effects by eating two sweet citrus fruits a day. Generally, citrus fruits that are flatter in shape, have fine and dense small particles on their peel, and are darker in color are sweeter. Conversely, if these particles are uneven and the peel feels rough, the pulp will be bland, and of course, its anti-cancer effect will be poor.
