吃光敏性食物易变黑？专家辟谣：做好防晒更重要
近日，关于吃“光敏性食物”是否容易变黑的说法引发关注。对此，权威专家辟谣称，按照正常的饮食习惯，吃芹菜等蔬菜并不会导致光毒性损伤。
据了解，“光敏性食物”是指食用后皮肤对阳光敏感性增加的食物。常见的光敏性食物包括芹菜、香菜、柠檬、无花果等。
专家指出，这些食物中含有的呋喃香豆素等物质确实具有光敏性，但其含量很低，正常食用并不会对皮肤造成明显影响。只有在大量食用并长时间暴露在烈日下时，才可能出现光毒性损伤，表现为皮肤发红、水肿、疼痛等。
因此，专家强调，无论是否食用光敏性食物，长时间暴露在烈日下都会有晒黑、晒伤的风险。做好防晒才是关键。
防晒措施包括：
* 涂抹防晒霜：选择SPF30以上、PA++以上、广谱防晒霜，每隔2-3小时补涂一次。
* 遮挡：戴帽子、太阳镜、穿长袖长裤，避免阳光直射。
* 避开高峰时段：上午10点至下午4点是紫外线最强的时段，尽量避免外出或采取更严格的防晒措施。
* 注意补水：多喝水，保持皮肤水分充足，有助于减少晒伤。
专家提醒，如果在食用光敏性食物后出现皮肤不适，应立即停止食用并及时就医。

**Headline:** Is It a Myth That Eating Photosensitive Foods Makes You Tan?
**Keywords:** Photosensitivity, Sun protection, Sunburn
**News Content:** Does eating photosensitive foods make you tan easily? Experts debunk the rumor: Sun protection is more important
Recently, there has been a lot of attention on whether eating “photosensitive foods” can make you tan easily. In response, authoritative experts have debunked the rumor, stating that eating vegetables such as celery, according to normal dietary habits, will not cause phototoxic damage.
Itis understood that “photosensitive foods” refer to foods that increase the skin’s sensitivity to sunlight after consumption. Common photosensitive foods include celery, coriander, lemon, and figs.
Experts point out that the furanocoumarins and other substances contained in these foods do have photosensitivity, but their content is very low, and normal consumption will not have a significant impact on the skin. Only when consumed in large quantities and exposed to strong sunlight for a long time, is it possible for phototoxic damage to occur, manifested as redness, edema, and pain in the skin.
Therefore, experts emphasize that regardless of whetheror not photosensitive foods are consumed, prolonged exposure to strong sunlight poses a risk of tanning and sunburn. Sun protection is key.
Sun protection measures include:
* Apply sunscreen: Choose a broad-spectrum sunscreen with an SPF of 30 or higher and a PA++ rating or higher, and reapply every 2-3 hours.
* Cover up: Wear a hat, sunglasses, and long sleeves and pants to avoid direct sunlight.
* Avoid peak hours: The hours between 10 am and 4 pm are when UV rays are strongest, so try to avoid going out or take stricter sun protection measures.
* Stay hydrated: Drink plenty of water to keep your skin hydrated, which helps reduce sunburn.
Experts remind us that if you experience skin discomfort after consuming photosensitive foods, you should stop eating them immediately and seek medical attention promptly.
