Most strokes could be prevented, according to new guidelines aimed at helping people and their doctors do just that. 

Stroke was the fourth-leading cause of death in the U.S. in 2023, according to the Centers for Disease Control and Prevention, and more than half a million Americans have a stroke every year. But up to 80% of strokes may be preventable with better nutrition, exercise and identification of risk factors. 

The first new guidelines on stroke prevention in 10 years from the American Stroke Association, a division of the American Heart Association, include recommendations for people and doctors that reflect a better understanding of who gets strokes and why, along with new drugs that can help reduce risk. 

The good news is that the best way to reduce your risk for stroke is also the best way to reduce your risk for a whole host of health problems — eat a healthy diet, move your body and don’t smoke. The bad news is that it’s not always so easy to sustain. 

Dr. Sean Duke, a stroke doctor at the University of Mississippi Medical Center, blames the forces in society that keep people sedentary and eating poorly, like cell phones and cheap, unhealthy food. “Our world is stacked against us,” he said. 

Here’s what to know about stroke and the new guidelines: 

What is a stroke? 

A stroke happens when blood flow to part of the brain is blocked or if a blood vessel in the brain bursts. That deprives the brain of oxygen which can cause brain damage that can lead to difficulty thinking, talking and walking, or even death. 

How eating healthy can reduce your risk for stroke 

Eating healthy can help control several factors that increase your risk for stroke, including high cholesterol, high blood sugar, and obesity, according to the heart association. 

The group recommends foods in the so-called Mediterranean diet such as fruits, vegetables, whole grains and olive oil, which can help keep cholesterol levels down. It suggests limiting red meat and other sources of saturated fat. Instead, get your protein from beans, nuts, poultry, fish and seafood. 

Limit highly processed foods and foods and drinks with a lot of added sugar. This can also reduce your calorie intake, which helps keep weight in check. 

Moving your body can help prevent strokes 

Getting up and walking around for at least 10 minutes a day can “drastically” reduce your risk, said Dr. Cheryl Bushnell, a neurologist at Wake Forest University School of Medicine who was part of the group that came up with the new guidelines. Among the many benefits: Regular exercise can help reduce blood pressure, a major risk factor for stroke. 

Of course, more is better: The heart association recommends at least 150 minutes of moderate aerobic or 75 minutes of vigorous activity — or some combination — per week. How you do it doesn’t matter so much, experts said: Go to the gym, take a walk or run in your neighborhood or use treadmills or stepper machines at home. 

New tools to reduce obesity, a risk factor for stroke 

Diet and exercise can help control weight, another important risk factor for strokes. But a new class of drugs that can drastically reduce weight have been approved by regulators, providing new tools to reduce stroke risk since guidelines were last updated. 

The guidelines now recommend that doctors consider prescribing these drugs, including those sold under the brand names Ozempic, Wegovy, Mounjaro and Zepbound, to people with obesity or diabetes. 

But while those drugs can help, people still need to eat well and get exercise, cautions Dr. Fadi Nahab, a stroke expert at Emory University Hospital. 

Guidelines help identify people who might be at higher risk 

The new guidelines for the first time recommend doctors screen patients for other factors that could increase stroke risk, including sex and gender and non-medical factors such as economic stability, access to health care, discrimination and racism. For example, the risk for having a first stroke is nearly twice as high for Black adults in the U.S. as it is for white adults, according to the CDC. 

“If somebody doesn’t have insurance or they can’t get to a doctor’s office because of transportation issues or they can’t get off work to get health care … these are all things that can impact the ability to prevent stroke,” Bushnell said. 

Doctors may be able to point to resources for low-cost health care or food, and can give ideas about how to be active without breaking the bank for a gym membership. 

The guidelines also now recommend doctors should screen for conditions that could increase a woman’s risk for stroke, such as high blood pressure during pregnancy or early menopause. 

How do I know if I’m having a stroke and what do I do? 

Three of the most common stroke symptoms include face weakness, arm weakness and difficulty speaking. And time is important, because brain damage can happen quickly and damage can be limited if a stroke is treated quickly. Stroke experts have coined an acronym to help you remember: FAST. F for face, A for arm, S for speech, and T for time. If you think you or a loved one could be having a stroke, call 911 right away.

GENEVA — Ahead of next week’s U.N. Climate Change Conference, or COP29, in Baku, Azerbaijan, health experts warn that the climate crisis is also a health crisis and say they must be addressed in tandem to save the planet for future generations.

“Human health and planetary health are intertwined,” U.N. Secretary-General Antonio Guterres said in a statement. “Countries must take meaningful action to protect their people, boost resources, cut emissions, phase out fossil fuels and make peace with nature.”

His call for action is buttressed by Tedros Adhanom Ghebreyesus, the WHO director-general, who calls COP29 “a crucial opportunity for global leaders to integrate health considerations into strategies for adapting to and mitigating climate change.”

In preparation for the climate summit, the World Health Organization, in collaboration with more than 100 organizations and 300 experts, has developed a plan of action to protect the health of all people, “particularly the estimated 3.6 billion people who live in areas which are most susceptible to climate change.”

“This document is a collective call from the health community to make sure that everybody understands the devastating impacts that climate change is having on our health” and to know what actions must be taken to prevent the worst from happening, Dr. Maria Neira, director of the WHO’s Environment Department, told journalists at a briefing Thursday.

“We must move away from fossil fuel subsidies,” she said, noting that “implementing fair carbon pricing and, of course, mobilizing the finance that is needed for climate and health action could save millions of lives every year.”

WHO data show the many ways in which climate change threatens human lives. Between 2030 and 2050, the WHO estimates that climate change will cause 250,000 additional deaths every year “from malnutrition, malaria, diarrhea and heat stress alone.”

Without preventive action, the WHO warns, temperature and precipitation changes will spread death and illness from vector-borne diseases, which currently stand at more than 700,000 a year. It says heat-related deaths among people over age 65 have risen by 70% in two decades and are likely to rise further as the planet heats up.

“If we were to meet the Paris Agreement goals, we would save somewhere in the region of a million lives a year from reduced air pollution alone,” said Dr. Diarmid Campbell-Lendrum, WHO team lead for climate change and health.

The 2016 Paris Agreement on climate change enjoins nations to keep greenhouse gas emissions from rising 1.5 degrees Celsius above preindustrial levels. The U.N. environment agency’s annual emissions gap report, however, finds the world is headed in the wrong direction, with temperatures likely to rise to 3.1 degrees Celsius above preindustrial levels by the end of the century if preventive action is not taken.

“At the moment, the world is currently massively subsidizing fossil fuel consumption,” Campbell-Lendrum said. “The costs of fossil fuel consumption are not only felt in the atmosphere, they are felt in people’s lungs, old people’s lungs, triggering heart attacks and so on, but also young people’s lungs, impairing their development, giving them asthma, hampering their life chances.

“If we were to invest those resources more wisely, then we would have both a healthier planet and also much healthier populations,” he said, adding that financing climate action “is a really good investment, in that you get a lot more back than you put in.”

“We will be able to save almost 2 million lives a year and bring in $4 in benefits for every $1 that you invest in climate action,” he said.

His colleague, Dr. Vanessa Kerry, WHO director-general special envoy for climate change health, agreed that the world cannot afford to ignore the warnings of the impact of climate change on health.

“Whether we choose to recognize it or not, climate change is here. Its impacts are accelerating, altering our ecosystems and communities and threatening our lives.

“Poor health destabilizes economies, widens inequalities and drives political unrest,” she said. “When people cannot access essential needs for their families and lives, it leads to political and social instability. We must address health as a fundamental part of our climate response to prevent these cascading effects.”

Kerry called on leaders gathering for COP29 to urgently “fast-track a just transition and increase funding for health systems” and for frontline health workers to protect the most vulnerable.

ABBOTS LANGLEY, England — Originally built to store crops from peasant farmers, the Tithe Barn on the edge of the English village of Abbots Langley was converted into homes that preserve its centuries of history. Now, its residents are fighting to stop a development next door that represents the future.

A proposal to build a data center on a field across the road was rejected by local authorities amid fierce opposition from villagers. But it’s getting a second chance from British Prime Minister Keir Starmer’s government, which is pursuing reforms to boost economic growth following his Labour party’s election victory in July.

Residents of Abbots Langley, 30 kilometers northwest of London, worry the facility will strain local resources and create noise and traffic that damages the character of the quiet village, which is home to more than 20,000 people. Off the main street there’s a church with a stone tower built in the 12th century and, further down the road, a picturesque circular courtyard of rustic thatched-roof cottages that used to be a farm modeled on one built for French Queen Marie Antoinette.

“It’s just hideously inappropriate,” said Stewart Lewis, 70, who lives in one of the converted houses in the 600-year-old Tithe Barn. “I think any reasonable person anywhere would say, ‘Hang on, they want a data center? This isn’t the place for it.'”

As the artificial intelligence boom fuels demand for cloud-based computing from server farms around the world, such projects are pitting business considerations, national priorities and local interests against each other.

Britain’s Deputy Prime Minister Angela Rayner has stepped in to review the appeals filed by developers of three data center projects after they were rejected by local authorities, taking the decision out of the hands of town planners. Those proposals include Abbots Langley and two projects in Buckinghamshire, which sits west of London. The first decision is expected by January.

The projects are controversial because the data centers would be built on “greenbelt” land, which has been set aside to prevent urbanization. Rayner wants to tap the greenbelt for development, saying much of it is low quality. One proposed Buckinghamshire project, for example, involves redeveloping an industrial park next to a busy highway.

“Whilst it’s officially greenbelt designated land, there isn’t anything ‘green’ about the site today,” said Stephen Beard, global head of data centers at Knight Frank, a property consultancy that’s working on the project.

“It’s actually an eyesore which is very prominent from the M25” highway, he said.

Greystoke, the company behind the Abbots Langley center and a second Buckinghamshire project to be built on a former landfill, didn’t respond to requests for comment. In an online video for Abbots Langley, a company representative says, “We have carried out a comprehensive search for sites, and this one is the very best.” It doesn’t specify which companies would possibly use the center.

The British government is making data centers a core element of its economic growth plans, deeming them “critical national infrastructure” to give businesses confidence to invest in them. Starmer has announced deals for new centers, including a 10 billion pound ($13 billion) investment from private equity firm Blackstone to build what will be Europe’s biggest AI data center in northeast England.

The land for the Abbots Langley data center is currently used to graze horses. It’s bordered on two other sides by a cluster of affordable housing and a highway.

Greystoke’s plans to construct two large buildings totaling 84,000 square meters and standing up to 20 meters tall have alarmed Lewis and other villagers, who worry that it will dwarf everything else nearby.

They also doubt Greystoke’s promise that it will create up to 260 jobs.

“Everything will be automated, so they wouldn’t need people,” said tech consultant Jennifer Stirrup, 51, who lives in the area.

Not everyone in the village is opposed.

Retiree Bryan Power says he would welcome the data center, believing it would benefit the area in a similar way as another big project on the other side of the village, the Warner Bros.’ Studio Tour featuring a Harry Potter exhibition.

“It’ll bring some jobs, whatever. It’ll be good. Yeah. No problem. Because if it doesn’t come, it’ll go somewhere else,” said Power, 56.

One of the biggest concerns about data centers is their environmental impact, especially the huge amounts of electricity they need. Greystoke says the facility will draw 96 megawatts of “IT load.” But James Felstead, director of a renewable energy company and Lewis’ neighbor, said the area’s power grid wouldn’t be able to handle so much extra demand.

It’s a problem reflected across Europe, where data center power demand is expected to triple by the end of the decade, according to consulting firm McKinsey. While the AI-fueled data boom has prompted Google, Amazon and Microsoft to look to nuclear power as a source of clean energy, worries about their ecological footprint have already sparked tensions over data centers elsewhere.

Google was forced to halt plans in September for a $200 million data center in Chile’s capital, Santiago, after community complaints about its potential water and energy usage.

In Ireland, where many Silicon Valley companies have European headquarters, the grid operator has temporarily halted new data centers around Dublin until 2028 over worries they’re guzzling too much electricity.

A massive data center project in northern Virginia narrowly won county approval last year, amid heavy opposition from residents concerned about its environmental impact. Other places like Frankfurt, Amsterdam and Singapore have imposed various restrictions on data centers.

Public knowledge about the industry is still low but “people are realizing more that these data centers are quite problematic,” said Sebastian Lehuede, a lecturer in ethics, AI and society at King’s College London who studied the Google case in Chile.

As awareness grows about their environmental impact, Lehuede said, “I’m sure we will have more opposition from different communities.”

New Delhi — The electric vehicle industry is closely watching to see how Tesla boss Elon Musk, who played a key role in the victory of Republican President-elect Donald Trump, will use his influence with the incoming president to steer the industry’s future.

At stake are several issues including the new administration’s approach to tariffs on Chinese EVs and tax credits. In anticipation of decisions favorable to Tesla, shares in the company rose 27% after the election result was announced, taking its market capitalization to $1 trillion.

During the campaign, Trump said he would increase tariffs on Chinese goods and roll back tax credits available to EV buyers in the U.S. He also vowed to reduce or eliminate many vehicle emissions standards under the Environmental Protection Agency, which support the EV industry.

Industry analysts are divided on whether high tariffs on Chinese EVs are advantageous or disadvantageous for Tesla’s business. Some analysts have suggested that Musk could persuade the Trump administration to reduce the tariffs on Chinese EVs and might even temper the overall tariff regime against Chinese goods.

However, Musk is likely to support the elimination of the $7,500 tax credit given to EV buyers in the United States. The absence of tax credits would make it difficult for legacy carmakers to introduce EV versions of their cars in competition with Tesla.

“As Elon Musk played a very important role in funding Trump’s campaign, he will no doubt have the ear of the U.S. president and play a role that will help shape policies that are advantageous to Tesla and his other businesses,” Bill Russo, founder and CEO of Automobility Limited, a Shanghai-based strategic consulting and investment platform, told VOA.

To be sure, Musk opposed U.S. tariffs on China-made EVs last May. “Neither Tesla nor I asked for these tariffs. In fact, I was surprised when they were announced. Things that inhibit freedom of exchange or distort the market are not good,” Musk said after the Biden administration enhanced tariffs on Chinese EVs.

The question is whether he will continue to oppose tariffs on Chinese EVs after Trump enters the White House. A section of analysts has predicted that Musk would continue this line of argument because China accounts for one-third of Tesla sales.

“Tesla is in China because Elon Musk needs the scale and efficient cost structure of the Chinese supply chain to make the company more competitive around the world,” Russo said.

China makes over 70% of the EV batteries in the world and almost two-thirds of all EVs and related components. “Tariffs make accessing this supply chain more costly, and that does not help Tesla,” he said.

Between January and May this year, Tesla sold almost as many cars in China as it did in the United States. Chinese consumers bought one-third of Tesla cars of all models totaling 513,644. In the same period, the company sold 522,444 vehicles in the U.S.

Wedbush Securities analyst Dan Ives argued that higher tariffs would help Tesla compete better with Chinese EVs in the U.S. market.

“Tesla has the scale and scope that is unmatched in the EV industry and this dynamic could give Musk and Tesla a clear competitive advantage in a non-EV subsidy environment, coupled by likely higher China tariffs that would continue to push away cheaper Chinese EV players (BYD, Nio etc.) from flooding the U.S. market over the coming years,” Ives said in a note to clients this week.

Taking a different view, Beatrix C. Keim, director of Germany-based Centre Automotive Research, said the next president is unlikely to listen to arguments for reducing tariffs on Chinese EVs.

“There is a 100% tariff for Chinese EVs in place. I don’t think that Trump will weaken this,” she said. The high tariff does not affect Tesla because it does not export cars from its Shanghai plant for the U.S. market, and builds them in the U.S.

Keim said Musk will do whatever serves Tesla’s business in China. “Chinese people are very likely to react emotionally if he is perceived as acting against China’s interest,” she said. “Chinese customers had once blocked the sales of Tesla cars, and this can happen again.”

Musk said last April that he loved the Chinese people.

“I’m a big fan of China. I also have a lot of fans in China. Well, the feelings are reciprocated,” Musk, who has often been described in Chinese social media as a “friend of China,” said in April.

Tesla is set to introduce a new fully self-driving (FSD – Supervised) car in the coming months, though the vehicle’s safety remains under review. Musk must have sufficient influence in both Washington and Beijing to obtain the regulatory approvals necessary to sell it.

“China is likely to approve FSD as it would like to show goodwill toward foreign technology,” Russo said. However, Tesla’s FSD may have a limited market in China where local manufacturers play a much bigger role.

Keim said Tesla’s FSD might not face regulatory challenges in Europe, but it may be difficult for it to find enough customers in the face of local competition.

One of the questions that is often asked is whether China would retaliate by imposing higher tariffs on American goods, including Tesla.

“This is very unlikely, as Tesla has invested in China and is used as an example of how foreign brands are still welcome in China, and Tesla is held up as a benchmark for Chinese companies to measure against,” Russo said.

“Killing competition is not viewed as healthy for the forward development of the Chinese automakers. This is in stark contrast to the way the U.S. has acted so far.”
