Good morning, everyone.
早上好，各位。
Welcome to TalkCast, your daily English news podcast.
欢迎来到 TalkCast，你们的每日英语新闻播客。
Today is October 15th, 2026.
今天是 2026 年 10月 15 日。
I am Liam, your lead anchor.
我是利亚姆，你们的主播主持人。
And good morning from me.
我也向大家道个早安。
I am Emma.
我是埃玛。
It is wonderful to start another bright morning with all of you.
能和大家一起开始一个明媚的早晨，真是太棒了。
Grab your cup of coffee or warm tea because we have a lot of fascinating stories today.
拿上你的咖啡或热茶，因为我们今天有很多引人入胜的故事。
We certainly do, Emma.
我们确实是这样，埃玛。
Today we are focusing on health, technology, and practical science that can improve our daily lives.
今天我们关注健康、技术和能改善我们日常生活的实用科学。
Here is a quick look at our main headlines.
以下是我们主要头条新闻的速览。
First, doctors report that the seasonal flu is arriving several weeks earlier than usual this year.
首先，医生报告说，今年季节性流感比往常提前了几周到来。
Next, researchers have trained artificial intelligence to predict heart risks while patients sleep.
接下来，研究人员训练了人工智能，在患者睡觉时预测心脏风险。
After that, we look at a surprising study about how a spoonful of olive oil before a meal can help
之后，我们来看一项关于饭前一勺橄榄油如何有助于……的惊人研究
manage blood sugar.
控制血糖。
And finally, we will explore why lifting weights is actually great news for your heart.
最后，我们将探讨为什么举重对你的心脏其实是个好消息。
Those sound like topics that everyone can use.
听起来这些都是每个人都能用到的话题。
Let us jump right into our first story, Liam.
让我们直接切入第一个故事，利亚姆。
What is going on with the flu season?
流感季到底怎么了？
Well, public health agencies are warning that influenza cases are already rising in mid -October.
嗯，公共卫生机构警告说，流感病例在 10 月中旬就已经在上升了。
Usually, we do not see numbers like this until late November or December.
通常，我们直到 11 月底或 12 月才会看到这样的数字。
Because of this early rise, doctors are urging people to think about their annual flu shots right now.
由于这种早期上升，医生敦促人们 现在就考虑他们年度的流感疫苗接种。
Wait, it is only October.
等等，现在才 10 月。
Does that mean the virus changed, or are our bodies just less prepared this year?
这是否意味着病毒变异了，或者今年我们的身体只是准备得不够充分？
Scientists say it is partly due to changing weather patterns and how people gather indoors as autumn
科学家表示，这部分是由于天气模式的变化以及随着秋季到来人们在室内聚集
cools down.
变凉。
When temperatures drop suddenly, viruses can spread much more easily from person to person.
当气温突然下降时，病毒可以非常轻易地在人与人之间传播。
Health experts explain that when you receive a vaccine, your immune system needs about two weeks to
健康专家解释说，当你接种疫苗时，你的免疫系统需要大约两周时间来
build strong defenses.
建立强大的防线。
So if the virus is already active, waiting until winter might be too late.
所以如果病毒已经很活跃，等到冬天可能就太迟了。
That makes total sense.
这完全讲得通。
It is like winter weather arriving before you have found your heavy winter coat.
这就好比冬天的天气到来之前，你还没找到厚重的冬衣。
If you wait until it snows, you will catch a chill before you can stay warm.
如果你等到下雪才行动，在保暖之前你就会着凉。
That is an excellent comparison.
这是一个极好的比喻。
Doctors also emphasize basic habits that people often forget.
医生们还强调了人们经常忘记的基本习惯。
Washing your hands with soap for 20 seconds, opening windows to let fresh air circulate, and staying
用肥皂洗手 20 秒，开窗让新鲜空气流通，以及保持
home if you have a fever can stop the virus from spreading to classmates or coworkers.
如果发烧就待在家里，这样可以阻止病毒传播给同学或同事。
Simple habits really do save lives.
简单的习惯确实能拯救生命。
And speaking of staying healthy, Liam, our next story combines medical care with advanced technology.
说到保持健康，利亚姆，我们的下一个故事将医疗护理与先进的技术结合起来。
Tell us about this new sleep research.
给我们讲讲这项新的睡眠研究吧。
This is a really exciting breakthrough published in medical journals this week.
这是本周发表在医学期刊上一个令人兴奋的突破。
Researchers have developed a deep learning computer model that analyzes signals during sleep studies.
研究人员开发了一个深度学习计算机模型，用于分析睡眠研究期间的信号。
In the past, sleep studies mostly looked for breathing problems like sleep apnea.
过去，睡眠研究主要寻找诸如睡眠呼吸暂停之类的呼吸问题。
However, this new artificial intelligence system examines electrical signals from the heart while a
然而，这个新的人工智能系统在一个人睡觉时检查来自心脏的电信号
person is asleep.
处于睡眠状态。
Hold on a moment, Liam.
等一会儿，利亚姆。
When you say deep learning, can you explain what that means for our listeners who are not computer experts?
当你提到深度学习时，你能解释一下这对不是计算机专家的听众意味着什么吗？
Of course.
当然可以。
Deep learning is a type of artificial intelligence.
深度学习是一种人工智能。
You can think of it like a computer brain that learns from thousands of examples.
你可以把它想象成一个从成千上万个例子中学习的计算机大脑。
In this study, the computer looked at thousands of sleep recordings from past patients.
在这项研究中，计算机查看了过去患者的数千份睡眠记录。
Over time, it learned to spot tiny patterns and heartbeats that human doctors could easily miss.
随着时间的推移，它学会了识别人类医生很容易错过的微小模式和心跳。
And what did these tiny patterns show?
这些微小的模式显示了什么？
The study found that these subtle electrical patterns can predict cardiovascular risks years before
研究发现，这些微妙的电信号模式可以在数年前预测心血管风险
any serious illness happens.
任何严重疾病发生之前。
In other words, the AI can detect if someone has a higher risk of heart trouble in the future just
换句话说，人工智能可以检测某人在未来是否有更高的心脏问题风险
by watching their nighttime heart rhythms.
通过观察他们夜间的心脏节律。
Cardiovascular is a big medical word.
心血管是一个很大的医学词汇。
Can you break that down for us? Certainly.
你能为我们详细解释一下吗？当然。
Cardiovascular simply refers to the heart and all the blood vessels that carry blood through your body.
心血管简单来说是指心脏以及输送血液流经全身的所有血管。
Cardio means heart and vascular means blood vessels.
Cardio 代表心脏，vascular 代表血管。
Thank you.
谢谢你。
That helps.
这很有帮助。
It is incredible to imagine that while you are resting and dreaming, your heart is telling a quiet
很难想象，当你正在休息和做梦时，你的心脏正在诉说一个安静的
story about your overall health.
关于你整体健康的故事。
It is like a mechanic doing an engine check while your car is parked overnight in the garage. Exactly.
这就像当你的车夜间停在车库时，机械师在检查发动机一样。完全正确。
The researchers hope that routine sleep tests could soon become an easy, non -invasive way to protect
研究人员希望常规睡眠测试很快能成为一种简单、无创的方式来保护
people from heart disease before symptoms even begin.
人们免受心脏病的侵害，甚至在症状出现之前。
That could help so many people get treatment early.
这可以帮助许多人尽早获得治疗。
Now, from nighttime sleep, let us move to what we put on our breakfast plates.
现在，从夜间睡眠，让我们转向我们放在早餐盘子里的东西。
You mentioned an interesting finding about olive oil and carbohydrates. Yes.
你提到了一个关于橄榄油和碳水化合物的有趣发现。是的。
This study looks at food order and metabolism.
这项研究着眼于食物顺序和新陈代谢。
Nutrition researchers conducted an experiment where participants consumed a small amount of extra
营养研究人员进行了一项实验，其中参与者摄入了少量的额外
virgin olive oil about 15 minutes before eating carbohydrates like bread, pasta, or rice.
特级初榨橄榄油，在吃面包、面食或米饭等碳水化合物之前大约 15 分钟。
Olive oil before carbs?
先吃橄榄油再吃碳水？
Many Mediterranean cultures already dip bread in olive oil.
许多地中海文化已经有用面包蘸橄榄油的习惯。
Why does having the oil first matter?
为什么先吃油很重要？
It turns out the order changes how the digestive system works.
事实证明，顺序改变了消化系统的工作方式。
When healthy fat enters the stomach first, it triggers digestive hormones that slow down the
当健康脂肪首先进入胃部时，它会触发消化荷尔蒙，从而减缓
movement of food into the small intestine.
食物进入小肠的运动。
Because digestion slows down, the sugar from the carbohydrates enters the bloodstream gradually
由于消化减慢，碳水化合物中的糖分会逐渐进入血液
instead of all at once.
而不是一次性全部进入。
So instead of a huge sugar spike, you get a gentle, steady rise in energy? Precisely.
所以，没有巨大的血糖飙升，你只会得到温和、稳定的能量上升？正是如 此。
When your blood sugar spikes quickly, your body produces a large surge of insulin to bring the sugar
当你的血糖迅速飙升时，你的身体会产生大量的胰岛素来把糖分
level down.
降下来。
That often leaves you feeling tired, hungry again, and foggy headed an hour later.
这通常会让你在一小时后感到疲倦、再次饥饿以及头脑不清醒。
Over many years, frequent spikes can also increase the risk of type 2 diabetes.
多年以后，频繁的血糖飙升还会增加患 2 型糖尿病的风险。
I love practical tips like that.
我喜欢这样实用的小建议。
So healthy fats act like a speed bump on a road.
因此，健康脂肪就像路上的减速带一样。
They prevent carbohydrates from speeding into your bloodstream too fast.
它们阻止碳水化合物过快地进入你的血液。
That speed bump metaphor is perfect.
那个减速带的比喻太贴切了。
In a related study, scientists also compared two meals that had the exact same calories and nutrients.
在相关研究中，科学家们还比较了两餐，它们具有完全相同的卡路里和营养成分。
However, one meal was made from whole foods, and the other was made from ultra -processed ingredients.
然而，一餐是由全食物制成的，另一餐是由超加工成分制成的。
The ultra -processed meal caused a significantly higher insulin surge.
超加工餐食导致了显著更高的胰岛素激增。
That proves that food quality and food structure matter just as much as counting calories.
这证明了食物质量和食物结构与计算卡路里同样重要。
It is not only what we eat, but how that food is prepared and when we eat it.
这不仅在于我们吃什么，还在于食物是如何烹制的以及我们什么时候吃它。
Very true.
非常正确。
And that brings us to our final story of the morning, which is about physical activity and longevity.
这也把我们带到了今天早上的最后一个故事，关于体力活动和长寿。
A new medical report is encouraging adults to reconsider strength training.
一份新的医学报告正在鼓励成年人重新考虑力量训练。
Now, Liam, when most people hear the words weightlifting or strength training, they picture young
现在，利亚姆，当大多数人听到举重或力量训练这个词时，他们会想象年轻的
bodybuilders in a gym lifting huge metal bars.
健身房里正在举起巨大金属杠铃的健美运动员。
Is that what doctors are talking about?
这就是医生们在谈论的事情吗？
Not at all, Emma.
一点也不，埃玛。
Cardiologists say that any form of resistance exercise can protect your heart as you age.
心脏病专家表示，随着年龄的增长，任何形式的抗阻运动都能保护你的心脏。
That includes simple exercises using light dumbbells, elastic resistance bands, or even your own
这包括使用轻型哑铃、弹力带甚至你自己的简单运动
body weight, like doing push -ups against a kitchen counter or gentle squats.
体重，比如在厨房台面上做俯卧撑或温和的深蹲。
Why is building muscle so important for the heart?
为什么锻炼肌肉对心脏如此重要？
I thought running or jogging was the only exercise for heart health.
我以为跑步或慢跑是心脏健康的唯一运动。
Running is great, but muscle tissue acts like an active metabolic organ.
跑步很好，但肌肉组织的作用就像一个活跃的代谢器官。
When you keep your muscles strong, they absorb glucose directly from your blood, which helps control
当你保持肌肉强壮时，它们直接从血液中吸收葡萄糖，这有助于控制
blood sugar naturally.
自然控制血糖。
In addition, resistance exercise improves blood pressure and keeps your arteries flexible.
此外，抗阻运动可以改善血压，并保持你的动脉血管弹性。
Research shows that people who combine walking with light strength exercises live longer, healthier
研究表明，将散步与轻量力量练习结合起来的人活得更久、更健康
lives than those who only do cardio.
生活得比那些只做有氧运动的人更长寿、更健康。
That is very encouraging news for adults of any age.
对于任何年龄段的成年人来说，这都是一个非常令人鼓舞的消息。
You do not have to spend hours in an expensive fitness club.
你不需要在昂贵的健身俱乐部花上几个小时。
You can just do 15 minutes of simple strength movements at home while listening to your favorite podcast. Exactly.
你可以在家里花 15 分钟做一些简单的力量动作，同时听你最喜欢的播客。没错。
A little bit of consistency every single day adds up to huge health benefits over time.
日复一日的坚持，随着时间的推移会带来巨大的健康益处。
We have covered so much today.
我们今天涵盖了如此多的内容。
Preparing early for the flu, using technology to watch our heart health while we sleep, pacing our
尽早为流感做准备，在睡觉时使用科技手段监测我们的心 脏健康，调整我们的
food for steady energy, and moving our bodies with strength.
为了获得稳定的能量而合理安排食物，以及通过力量锻炼身体。
