这3种水果伤胃!再馋,也不建议多吃!

入秋,水果接连上市。但要注意,并非所有水果都“人畜无害”,有些水果“天生反骨”,吃多了,反而伤害身体!

以下3种水果,堪称“胃部刺客”!再馋,也不建议多吃!

刺客1号:柿子

每年秋天,因为食用过多柿子导致胃结石甚至肠梗阻的新闻屡见不鲜。

究其原因,是柿子里存在一种叫鞣酸的物质,它的口感偏涩,具有收敛性,能使组织收缩、蛋白质凝固。

当这些鞣酸蛋白沉积在胃里,又与柿子果肉内的果胶来回纠缠,就形成了“胃柿石”。

Persimmons contain tannic acid, which has an astringent effect and can cause proteins to coagulate. When tannic acid binds with proteins and combines with pectin in the fruit, it can form a "gastric bezoar" — a stone-like mass in the stomach.

患者可能会出现上腹坠胀感、呕吐、吃点东西就饱了的情况,有时,也会破坏消化道黏膜导致出血,甚至引起肠套叠、肠梗阻等并发症。特别是曾经接受过消化道手术的人群,要格外小心!

Symptoms include upper abdominal bloating, vomiting and feeling full after eating only a little. In severe cases, it can damage the digestive tract, cause bleeding, or lead to complications such as intussusception and bowel obstruction.

那么,对于爱吃柿子的人来说,如何正确食用呢?

① 优先选择“完全甜型”柿子

甜型柿子在树上自然成熟,完全脱涩后,鞣酸的含量可以到0.5%以下,对肠胃不好的人来说相对安全。

② 尽量去皮吃

柿子成熟后,鞣酸主要集中于柿皮,去皮吃,或者不吃靠近皮部的果肉,可以相对减少鞣酸的摄入。

③ 吃柿饼代替柿子

柿子经过晾晒、发酵、氧化等步骤成为柿饼,部分鞣酸会被降解或转化,与蛋白质的结合能力下降,形成胃石的风险相应也会降低。

④ 避免空腹吃柿子

空腹时胃酸浓度高,柿子内的鞣酸更容易与蛋白质结合形成胃石,建议不要空腹吃柿子,尤其是未完全脱涩的柿子。

To eat persimmons more safely: choose fully sweet, naturally ripened varieties, which contain less than 0.5% tannic acid; peel them, since tannic acid is concentrated in the skin; eat dried persimmons instead, as drying and fermentation reduce tannic acid; and avoid eating them on an empty stomach, when stomach acid is more concentrated.

刺客2号:山楂

很多人对山楂的第一印象是开胃、消食。

确实。研究表明,山楂含有丰富的有机酸,可以刺激胃酸分泌,适量食用能帮助分解食物中的蛋白质和脂肪;其中果胶还可以促进肠道蠕动,有助于促进消化,缓解便秘。

但需要注意的是,山楂和柿子一样,同样藏着鞣酸。与此同时,过量山楂里的高浓度果酸会导致胃酸分泌过度,从而引发胃痛、反酸、烧心,甚至加重胃炎或胃溃疡。

Hawthorn is often seen as a digestive aid. In moderation, it can help break down proteins and fats and promote bowel movement.

But it also contains tannic acid. In large amounts, its high concentration of fruit acids can overstimulate stomach acid, causing pain, acid reflux, heartburn, and worsening gastritis or ulcers.

所以,建议大家吃山楂时注意适量,无论是吃新鲜山楂,还是糖葫芦,又或者是雪球山楂,一天不超过10颗为宜。对于肠胃不适的人群,建议在医生指导下谨慎食用。

It's best to limit intake to no more than 10 a day, whether fresh, candied or coated in sugar. People with stomach problems should be cautious and follow medical advice.

刺客3号:鲜枣

鲜枣作为当下的热门水果,尤其对于“懒人党”来说,吃鲜枣时连皮一起吃,方便省事。而且,枣皮富含膳食纤维,对促进肠道蠕动也有一定的好处。

但对于患有胃炎、胃溃疡的人群来说,鲜枣中的高纤维和其中的果酸则可能会加重胃部负担,刺激胃黏膜进一步受损,导致烧心、胃痛。

Fresh jujubes are convenient to eat, and the skin is rich in dietary fiber. But for people with gastritis or ulcers, their high fiber and fruit acids can strain the stomach and irritate the lining.

北京友谊医院消化科医生提醒:鲜枣的枣皮含有大量不溶性纤维素,吃太多会损害消化功能、伤胃。此外,食用鲜枣时,建议大家小心食用,避免误吞枣核,轻则划伤消化道,严重时甚至可能导致穿孔。

Doctors at Beijing Friendship Hospital warn that the skin contains large amounts of insoluble fiber, which can impair digestion if eaten in excess. People should also be careful not to swallow the pits, which can scratch the digestive tract or even cause perforation.

所以,以上这些水果,有你爱吃的吗?
