Peanuts are a popular snack
enjoyed by many people around the world. They are delicious, crunchy, and often
considered a healthy option because of their high protein and nutrient content.花生美味可口、香脆，其蛋白质和营养成分含量高，通常被认为是一种健康的食品，是世界各地许多人喜爱的零食。
However, recent research has
highlighted something important for people with cancer to consider when it
comes to eating peanuts.不过，最近的研究揭示，癌症患者在吃花生时需要考虑一些重要因素。
A study conducted by scientists
at the University of Liverpool looked at a specific protein found in peanuts
called Peanut agglutinin (PNA). This protein enters the bloodstream after
peanuts are eaten. The research team found that PNA might play a role in making
it easier for cancer to spread in the body.利物浦大学(University of Liverpool)的科学家进行的一项研究调查了花生中的一种特殊蛋白质——花生凝集素(简称PNA)。这种蛋白质会在食用花生后进入血液。研究小组发现，PNA可能会使癌症更容易在体内扩散。
Here’s how it works. PNA affects
the way blood vessels behave by triggering the release of chemicals called
cytokines. Two of these cytokines, named IL-6 and MCP-1, can make the lining of
blood vessels more receptive to cancer cells. This means that cancer cells can
attach to blood vessels more easily, making it simpler for them to travel to other
parts of the body—a process known as metastasis.其作用原理如下。PNA通过触发释放称为细胞因子的化学物质影响血管的行为方式。其中两种名为IL-6和MCP-1的细胞因子能使血管内壁更容易接受癌细胞。这意味着癌细胞更容易附着在血管上，从而更容易转移到身体的其他部位——这一过程被称为(癌症)转移。
In earlier studies, the same
research team discovered that PNA can stick to certain sugar molecules that are
commonly found on the surface of cancer and pre-cancer cells. This connection
acts like a glue, making cancer cells stick together in clusters. These
clusters are more likely to survive as they move through the bloodstream,
increasing the chances of the cancer spreading to new areas.在早些时候的研究中，同一个研究小组发现，PNA可以粘附在癌细胞和癌前细胞表面常见的某些糖分子上。这种连接就像胶水一样，使癌细胞聚集在一起。这些细胞簇在血液中移动时更有可能存活下来，从而增加癌症扩散到新部位的机会。
It’s important to note that this
research does not mean peanuts are harmful to everyone. For most people,
peanuts remain a healthy snack. However, the findings suggest that people who
are already dealing with cancer might want to be cautious about eating peanuts
regularly.值得注意的是，这项研究并不意味着花生对每个人都有害。对于大多数人来说，花生仍然是一种健康的零食。不过，研究结果表明，已经患有癌症的人可能要谨慎对待经常吃花生的问题。
For cancer patients, even small
factors that may encourage cancer to spread are worth paying attention to.对于癌症患者来说，即使是可能促使癌症扩散的小因素也值得注意。
The lead researcher, Dr. Lu-Gang
Yu, emphasized that this study is just the beginning. More research is needed
to fully understand the link between peanuts and cancer spread. The team is
calling for further studies to explore these findings in more depth.首席研究员于卢纲(Lu-Gang Yu，音译)博士强调，这项研究仅仅是个开始。要全面了解花生与癌症扩散之间的联系，还需要更多的研究。研究小组呼吁开展进一步研究，更深入地探讨这些发现。
For now, if you or someone you
know is undergoing cancer treatment, it might be a good idea to limit peanut
consumption until more is understood about the risks. It’s a small change that
could potentially make a difference.目前，如果您或您认识的人正在接受癌症治疗，在对风险有更多了解之前，限制食用花生可能是个好主意。虽只是一个小小的改变，却有可能带来不同的效果。 (喜欢就请关注)
