流鼻血跟上火没有一丁点儿的关系.
某些食物吃了让人流鼻血不是什么"上火", 而是因为某些食物富含水杨酸而抑制了凝血, 尤其是患有先天性毛细血管扩张症的人(英文叫Hereditary Hemorrhagic Telangiectasia, HHT, 也称Osler-Rendu-Weber syndrome---因内皮糖蛋白变异, 使血管变异)就特别敏感, 导致鼻腔毛细血管破裂出血, 因而容易出血. 跟什么上火没有一丁点儿的关系.

研究1) Lifestyle and Dietary Influences on Nosebleed Severity in Hereditary Hemorrhagic Telangiectasia
第一大类是酒精, 特别是红酒; 第二大类是辛辣食物; 第三最常见诱发鼻出血的是巧克力. 特别是黑巧克力; 第四大类是富含omega3的食物, 比如鱼油和三文鱼. 大蒜生姜人参也上榜.
研究2) What is salicylic acid and in which foods does it occur?
Salicylic acid is a colorless, crystalline organic acid that melts at 159°C; it is soluble in alcohol but is only slightly soluble in water. Salicylic acid is an ingredient used in many over-the-counter acne medications.
Fruits and vegetables are natural sources of salicylic acid, with fruits having large amounts of salicylates, particularly berries. Some herbs and spices contain quite high amounts, and meat, poultry, fish, eggs and dairy products all have little to no salicylates. Of the legumes, seeds, nuts, and cereals, only almonds, water chestnuts and peanuts have significant amounts. The table below gives more examples of foods containing salicylates:
