西方饮食会降低精子数量

吃大量的比萨饼,薯条和汉堡可以降低年轻健康男性的精子数量

一项新的研究发现,吃西式饮食通常充满了披萨,薯条,汉堡会对年轻男性产生精子的能力造成永久性伤害。也就是说,当他们吃西式饮食这么多时,他们的精子数量就会永远减少。

瑞士和美国研究人员进行的这项研究表明,如果他们遵循加工食品如加工肉类和含糖饮料,肉类如红肉和淀粉类碳水化合物的饮食,那么每次射精的精子减少了2500万,与那些食用量最少的人相比这些食物。

研究表明,年轻健康的男性如果吃了大量的比萨饼和汉堡以及其他加工食品,那么他们的精子数量就会比那些吃更多新鲜食物的人少得多。

该研究比较了几种类型的饮食,发现典型的西方饮食是最差的。西方饮食已经导致肥胖,心脏病,糖尿病和癌症的风险增加。目前的研究解释了为什么西方男性自20世纪70年代以来将平均精子数量降低了60%。

该研究基于来自3000名平均年龄为19岁的男性的数据,这些男性在进入丹麦武装部队之前提交了精子样本作为常规体检的一部分。

该研究发现,那些遵循谨慎均衡饮食与瘦肉,鱼,水果和蔬菜的男性精子总数最高。下一个最好的饮食是素食,其中包括大豆和鸡蛋,然后是斯堪的纳维亚饮食,其中包括更多的加工肉类,全谷物,冷水鱼和乳制品。

请记住,大豆不是精子计数的良好膳食成分。研究发现大豆摄入量与精子数量呈负相关。也就是说,高大豆摄入量与较低的精子数量有关。

Western diet lowers sperm counts

Eating a lot of pizza, chips and burgers lowers sperm count in young healthy men, Independent reports.

A new study finds that eating a Western diet that is typically full of pizza, chips, burgers can cause permanent damage to young men’s ability to produce sperm. That is, when they eat so much of a Western diet, they can have lower sperm counts forever.

The study conducted by Swiss and U.S. researchers shows men had 25 million fewer sperm per ejaculation if they follow a diet full of processed foods like processed meat and sugary drinks, meat like red meat, and starchy carbohydrates, compared to those who eat the least amount of these foods.

Young, healthy men who eat a lot of pizza chips and burgers and other processed foods can have much lower sperm counts than those who eat more fresh foods, according to the study.

The study compared a few types of diets and found the typical Western diet is among the worst.

Western diet has already linked to higher risk of obesity, heart disease, diabetes and cancer. The current study provides an explanation as to why Western men have lowered their average sperm counts by 60% since 1970s.

The study was based on data from 3000 men at an average age of 19 who submitted their sperm samples as part of routine medical exam before admitted into the Danish armed forces.

The study found that men who followed a prudent balanced diet with lean meats, fish, fruits and vegetables had the highest total sperm count. The next best diet is vegetarian diet which includes soy and eggs followed by a Scandinavian diet which consists of more processed meats, whole grains, cold water fish and dairy products.

Keep in mind that soy is not a good dietary component for sperm counts.   Studies have found an inverse association between soy intake and sperm counts.  That is, high soy intake was linked to lower sperm counts.
