Today is a very special day because it is October 1st, 2026.
今天是极其特殊的一天，因为今天是2026年10月1日。

Today, we have some truly amazing health and science stories to share with you.
今天，我们有一些真正令人惊叹的健康和科学故事要与大家分享。
That is right.
说得对。
Our main story today sounds like science fiction.
我们今天的主打故事听起来像科幻小说。
Scientists have discovered that old hearts can actually grow younger.
科学家们发现衰老的心脏实际上可以变得年轻。
We will also talk about a new flu vaccine, the best way to eat autumn fruits, and why supermarkets
我们还将讨论一种新的流感疫苗、吃秋季水果的最佳方式，以及为什么超市
are suddenly full of protein.
突然间充满了蛋白质。
That sounds like a great show.
听起来是个很棒的节目。
Let us start with our first big story, which was published in the journal Nature.
让我们从头条大新闻开始，该新闻发表在《自然》杂志上。
Scientists have found that when old hearts are transplanted into young bodies, the hearts actually
科学家们发现，当衰老的心脏被移植到年轻的身体中时，这些心脏实际上
become younger.
变得更年轻了。
Wait, did you say they become younger?
等等，你刚才说它们变年轻了吗？
Like they age backwards?
就像它们在倒退着变老一样？
That is hard to believe.
这真让人难以置信。
How is that even possible?
这甚至怎么可能呢？
It is true, Chloe.
这是真的，克洛伊。
Scientists call this biological age adjustment.
科学家称之为生物学年龄调节。
In the study, researchers looked at hearts that were transplanted from older donors into younger patients.
在这项研究中，研究人员观察了从年龄较大的捐赠者那里移植到年轻患者体内的心脏。
They found that after some time, the old heart cells started to act like young cells.
他们发现，一段时间后，衰老的心脏细胞开始表现得像年轻细胞一样。
Oh, I see.
哦，我明白了。
But first, what is biological age?
但首先，什么是生物学年龄？
Is it different from the age on my birthday card?
它和我生日卡片上的年龄不同吗？
Yes, it is.
是的，确实如此。
Your regular age is just the number of years you have lived.
你常规的年龄只是你生活过的年数。
But your biological age is about how healthy your cells are.
但你的生物学年龄关乎你的细胞有多健康。
If you live a healthy life, your biological age might be much younger than your real age.
如果你过着健康的生活，你的生物学年龄可能比你的实际年龄年轻得多。
That makes sense.
这很有道理。
So when the old heart goes into a young body, the young environment actually repairs the heart cells? Exactly.
所以当衰老的心脏进入年轻的身体时，年轻的环境实际上修补了心脏细胞？完全正确。
The young body sends positive signals through the blood.
年轻的身体通过血液发送积极的信号。
These signals help the old heart cells to fix themselves.
这些信号帮助衰老的心脏细胞自我修复。
It is like putting an old, tired machine into a clean, modern factory where it gets new oil and
这就像把一台老旧、疲惫的机器放进一个干净的现代工厂，在那里它获得新的机油，
works perfectly again.
然后又完美地运转起来。
That is a beautiful way to explain it.
这是一个精彩的解释方式。
This discovery could be huge for people who need heart transplants.
这一发现对需要心脏移植的人来说可能是巨大的。
It means we might be able to use hearts from older donors to save younger lives.
这意味着我们可能能够使用年龄较大捐赠者的心脏来拯救年轻的生命。
Yes, it could help many patients.
是的，它可以帮助许多患者。
Now, let us move on to our next story about staying healthy this autumn.
现在，让我们进入关于今年秋天保持健康的下一个故事。
As the weather gets cooler, the flu season is starting early this year.
随着天气变凉，今年的流感季节开始得比较早。
Oh, yes.
哦，是的。
I have noticed many people are already coughing.
我注意到许多人已经开始咳嗽了。
What can we do to protect ourselves, Matthew?
马修，我们能做些什么来保护我们自己呢？
Well, there is a new vaccine option this season.
嗯，这个季节有一个新的疫苗选择。
Doctors have announced the first mRNA flu vaccine for adults who are 50 and older.
医生们宣布了第一款针对50岁及以上成年人的mRNA流感疫苗。
Studies show that this new vaccine is more effective than traditional flu shots.
研究表明，这种新疫苗比传统的流感疫苗更有效。
That is interesting.
这真有趣。
But can you explain what an mRNA vaccine is?
但你能解释一下什么是mRNA疫苗吗？
Many people heard about it during the COVID -19 pandemic, but they might not know how it works for
许多人在COVID-19大流行期间听说过它，但他们可能不知道它是如何作用于
the flu. Sure.
流感的。当然。
Traditional vaccines use a weak or dead virus to teach your body how to fight the illness.
传统疫苗使用减毒或灭活的病毒来教你的身体如何对抗疾病。
But an mRNA vaccine is different.
但mRNA疫苗是不同的。
It is like a recipe card.
它就像一张食谱卡片。
It teaches your cells how to make a tiny, harmless part of the virus.
它教会你的细胞如何制造病毒微小且无害的部分。
Ah, okay.
啊，好的。
So our immune system sees this harmless part, practices fighting it, and then remembers how to
所以我们的免疫系统看到这个无害的部分，练习对抗它，然后记住如何
protect us if we meet the real virus later?
如果稍后遇到真正的病毒，如何保护我们？
Yes, that is correct.
是的，这很正确。
Because it is like a digital recipe, scientists can make it very quickly.
因为它就像一个数字食谱，科学家们可以非常快地制造它。
This is helpful because the flu virus changes every year, and we need new vaccines fast.
这很有帮助，因为流感病毒每年都在变异，我们需要快速获得新疫苗。
That sounds like a great shield for older adults.
这听起来像是老年人的一道伟大屏障。
My parents are over 50, so I will definitely tell them about this new option.
我父母超过50岁了，所以我一定会把这个新选择告诉他们。
That is a great idea, Chloe.
这是一个好主意，克洛伊。
Speaking of autumn health, let us talk about fruit.
说到秋季健康，我们来谈谈水果。
A new study of over 370 ,000 Americans has revealed a strong link between how you eat your fruit and
一项针对37万多美国人的新研究揭示了你吃水果的方式与
your heart health.
你的心脏健康之间存在着密切的联系。
How you eat your fruit?
你怎么吃水果？
Is there a wrong way to eat fruit?
吃水果难道还有错误的方法吗？
I usually drink a big glass of orange juice or apple juice in the morning.
我通常在早上喝一大杯橙汁或苹果汁。
Is that okay?
这可以吗？
Actually, the study suggests that drinking juice is not as good as eating whole fruit.
事实上，研究表明喝果汁不如吃整个水果好。
People who eat whole fruits regularly have a much lower risk of heart disease, but those who drink
经常吃整个水果的人患心脏病的风险要低得多，而那些喝
juice do not get the same protection.
果汁的人却得不到同样的保护。
Oh, really?
哦，真的吗？
But juice comes from fruit.
但果汁来自水果。
Why is drinking juice different from eating the fruit itself?
为什么喝果汁与吃水果本身不同？
The main difference is fiber, Chloe.
主要的区别在于纤维，克洛伊。
When you eat a whole apple, you eat a lot of fiber.
当你吃一个完整的苹果时，你吃了很多纤维。
This fiber acts like a slow gatekeeper.
这种纤维就像一个缓慢的守门人。
It slows down the sugar from the fruit, so your body absorbs it gradually.
它减缓了水果中的糖分，所以你的身体会逐渐吸收它。
And when we make juice, we throw away all that fiber?
当我们榨汁时，我们把所有的纤维都扔掉了吗？
Yes, we do.
是的，我们确实如此。
Without fiber, fruit juice is just a quick rush of sugar.
没有纤维，果汁只是一股快速涌入的糖分。
This sugar goes straight to your liver, which can cause health problems over time.
这种糖分直接进入你的肝脏，随着时间的推移会导致健康问题。
So eating whole apples, pears, and grapes this autumn is much better for your heart.
所以今年秋天吃整个苹果、梨和葡萄对你的心脏要好得多。
Okay, I understand.
好的，我理解了。
I will swap my morning juice for a real whole apple.
我会把我早上的果汁换成一个真正的完整苹果。
It is autumn, so apples are fresh and delicious anyway. Exactly.
现在是秋天，所以苹果无论如何都是新鲜且美味的。确实如此。
Now, let us talk about another big food trend.
现在，我们来谈谈另一个大的食品趋势。
If you have been to the supermarket recently, you might have noticed something strange.
如果你最近去过超市，你可能会注意到一些奇怪的事情。
Almost every product has the words high protein on the package. Yes.
几乎每个产品的包装上都有高蛋白字样。是的。
I have seen protein cookies, protein chips, and even protein water.
我见过蛋白质曲奇、蛋白质薯片，甚至蛋白质水。
Everyone seems to be obsessed with getting more protein.
每个人似乎都对摄入更多蛋白质着迷。
They call it protein maxing on social media.
他们在社交媒体上称之为蛋白质极限摄入。
Do we really need all this extra protein?
我们真的需要这么多额外的蛋白质吗？
According to nutritionists, the answer is probably no.
根据营养学家的说法，答案可能是否定的。
Most people who eat a balanced diet already get plenty of protein from regular food, like eggs,
大多数饮食均衡的人已经从常规食物（如鸡蛋）中获取了充足的蛋白质，
milk, fish, and beans.
牛奶、鱼和豆类。
You do not need to buy expensive processed protein snacks.
你不需要购买昂贵的加工蛋白质零食。
So supermarkets are just using protein maxing to make us spend more money.
所 以超市只是利用蛋白质极限摄入来让我们花更多的钱。
Yes, it is mostly a marketing trick.
是的，这主要是一种营销把戏。
However, there is one popular drink that experts actually recommend for your liver and brain, and
然而，有一种受欢迎的饮品是专家们确实为你的肝脏和大脑所推荐的，
that is coffee.
那就是咖啡。
Oh, thank goodness.
哦，谢天谢地。
I love coffee.
我喜欢咖啡。
Please tell me some good news about my favorite morning drink.
请告诉我一些关于我最喜爱的早晨饮品的好消息。
I have great news for you.
我有个好消息要告诉你。
Scientists have discovered what coffee really does to your gut and brain.
科学家们已经发现咖啡对你的肠道和大脑有什么真正的影响。
A new study shows that coffee can improve your gut microbes.
一项新的研究表明，咖啡可以改善你肠道的微生物。
These are the tiny, helpful bacteria that live in your stomach. Wow.
这些是生活在你胃里的微小、有益的细菌。哇。
I did not know coffee was good for my stomach, but how does that help my brain?
我不知道咖啡对我的胃有好处，但这怎么能帮助我的大脑呢？
Well, your gut and your brain are connected by a special communication system.
嗯，你的肠道和大脑是通过一个特殊的通讯系统连接在一起的。
When the bacteria in your gut are happy, they send positive signals to your brain.
当你肠道里的细菌处于活跃状态时，它们会向你的大脑发送积极的信号。
As a result, people who drink coffee often have lower levels of stress, depression, and anxiety.
因此，经常喝咖啡的人往往压力、抑郁和焦虑的水平较低。
That is amazing.
这太神奇了。
Does this only work with regular coffee or can people drink decaf too?
这只对普通咖啡有效，还是人们也可以喝低因咖啡？
You know, the coffee without caffeine.
你知道的，不含咖啡因的咖啡。
Actually, the study found that both caffeinated and decaf coffee had positive effects.
事实上，研究发现含咖啡因的和低因咖啡都有积极的效果。
So even if you do not want the energy boost, you can still drink decaf coffee to help your gut and
所以即使你不需要能量提升，你仍然可以喝低因咖啡来帮助你的肠道和
lower your stress.
减轻你的压力。
That is wonderful news for coffee lovers everywhere.
对世界各地的咖啡爱好者来说，这是个极好的消息。
I am going to enjoy my second cup of coffee today with a happy mind and a happy gut.
我今天要带着快乐的心情和快乐的肠道享用我的第二杯咖啡。
