吃光敏性食物会更容易变黑吗？
春季到来，阳光明媚，很多人喜欢在户外活动。但有传言称，食用芹菜等光敏性食物后，更容易被晒黑。对此，专家辟谣称，正常饮食不会导致光毒性损伤。
中国科学院植物研究所研究员刘夙表示，光敏性食物是指含有呋喃香豆素等物质的食物，这些物质在紫外线照射下会产生光毒性反应，引起皮肤炎症和色素沉着。
然而，正常饮食中摄入的光敏性物质含量很低，不足以引起光毒性损伤。刘夙指出，芹菜、香菜、柠檬等常见的光敏性食物，在日常饮食中食用并不会导致皮肤问题。
北京大学第一医院皮肤科主任医师杨淑霞也表示，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。因此，做好防晒措施至关重要。
杨淑霞建议，外出时应涂抹防晒霜，选择SPF30以上、PA++以上的产品。同时，应穿戴遮阳帽、太阳镜等防护用品。此外，避免在上午10点至下午4点阳光最强烈时段外出，或选择阴凉处活动。
专家提醒，如果在食用光敏性食物后出现皮肤红肿、瘙痒等不适症状，应及时就医，避免病情加重。

Can eating photosensitizing foods make you tan more easily?
Asspring arrives and the sun shines brightly, many people enjoy spending time outdoors. However, there are rumors that eating photosensitizing foods, such as celery, can make you more susceptible to tanning. Experts have debunked this claim, stating that normal dietary intake does not lead to phototoxic damage.
Liu Su, aresearcher at the Institute of Botany, Chinese Academy of Sciences, explains that photosensitizing foods contain substances such as furanocoumarins, which can produce phototoxic reactions when exposed to ultraviolet light, causing skin inflammation and pigmentation.
However, the amount of photosensitizing substances in a normal diet is too low to cause phototoxic damage. Liu Su points out that common photosensitizing foods such as celery, coriander, and lemon, when consumed in daily amounts, do not cause skin problems.
Yang Shuxia, chief physician of the Department of Dermatology at Peking University First Hospital, also states that regardless of whether you consumephotosensitizing foods, prolonged exposure to strong sunlight can lead to tanning and sunburn. Therefore, it is crucial to take sun protection measures.
Yang Shuxia recommends applying sunscreen when going outdoors, choosing products with SPF 30 or higher and PA++ or higher. Additionally, wear protective gear such as a sun hat and sunglasses. Avoid going out during the peak sunlight hours of 10 am to 4 pm, or choose to engage in activities in shaded areas.
Experts remind us that if you experience skin redness, itching, or other discomfort after consuming photosensitizing foods, seek medical attention promptly to prevent the condition from worsening.
