“Planet-friendly” foods may also help reduce a person’s risk of death from cancer, heart disease and other chronic illnesses by 25%, researchers have said.
Scientists in the US found those who followed a sustainable diet of more plant-based foods – such as whole grains, fruit, vegetables and nuts – were less likely to die over the course of 30 years compared with those who ate less environmentally friendly meals.
Based on their findings, presented at Nutrition 2023 – the annual meeting of the American Society for Nutrition in Boston, Massachusetts – the researchers have developed a new diet score that shows the effects of food on human health as well as the environment.
Known as the Planetary Health Diet Index (PHDI), it looks at existing evidence to give scores for foods.
The index takes into account the risk of chronic illnesses such as heart disease, bowel cancer, diabetes and stroke, as well as environmental impacts such as water use, land use, nutrient pollution and greenhouse gas emissions.
The team said their work builds on existing research which shows plant-based foods are healthier and less harmful to the planet than red and processed meats.
The researchers are hoping this tool will help policymakers and public health bodies develop strategies to improve public health while also addressing climate change.
Linh Bui, a PhD student in the Department of Nutrition at Harvard University’s TH Chan School of Public Health, said: “We proposed a new diet score that incorporates the best current scientific evidence of food effects on both health and the environment.

“The results confirmed our hypothesis that a higher Planetary Health Diet score was associated with a lower risk of mortality.”
After developing their tool, the researchers used it to determine and observe the outcomes of more than 100,000 people in the US, from 1986 to 2018.
More than 47,000 died during the follow-up period of more than 30 years.
The team found that higher PHDI scores were associated with a 15% lower risk of death from cancer or heart diseases, a 20% lower risk of death from neurodegenerative diseases, and a 50% lower risk of death from respiratory diseases.
Ms Bui said the PHDI may need to be adapted for different countries, depending on their culture or religion.
She also cautioned those with specific health conditions or food accessibility issues may find a planet-friendly diet more challenging.
Authorities have identified the 16 people killed in a massive blast at a munitions factory in rural Tennessee.
They were killed in an explosion on Friday at an Accurate Energetic Systems facility around 60 miles southwest of Nashville. The company researches and supplies explosives for the military.
Investigators are still working to discover the cause of the explosion.

Those killed were: Jason Adams, Erick Anderson, Billy Baker, Adam Boatman, Christopher Clark, Mindy Clifton, James Cook, Reyna Gillahan, LaTeisha Mays, Jeremy Moore, Melinda Rainey, Melissa Stanford, Trenton Stewart, Rachel Woodall, Steven Wright and Donald Yowell.

At a news conference, Humphreys County Sheriff Chris Davis said people in the community probably at least knew relatives of the victims killed in the explosion.
“It’s just small county, rural America, where everybody knows each other and everybody’s gonna take care of each other,” he said.

Authorities said there were no survivors of the blast, which left twisted and burning metal in its wake.
They said they were working to clear the area of hazards, including explosives, and identify remains.
Once the area is clear they can begin investigating what caused the explosion, said Matthew Belew, acting special agent in charge of the Bureau of Alcohol, Tobacco, Firearms and Explosives.
He said some of the relevant evidence was spread out over miles.
“It’s almost like putting a puzzle back together,” he added.
“We have worked closely with AES to look at pictures, look at blueprints, any of the identifying things that were in the building. And then we slowly methodically start to put some of that stuff together.”
Sir Keir Starmer will join world leaders at a historic summit in Egypt today – to witness the signing of the Gaza peace plan to end two years of conflict, bloodshed and suffering that has cost tens of thousands of lives and turned Gaza into a wasteland.
Travelling over to Egypt, flanked by his national security adviser Jonathan Powell, the prime minister told me it was a “massive moment” and one that is genuinely historic.
In the flurry of the following 48 hours, Sir Keir and another 20 or so leaders were invited to Egypt to bear witness to the signing of this deal, with many of them deserving some credit for the effort they made to bring this deal around – not least the leaders of Qatar, Egypt and Turkey, who pressed Hamas to sign up to this deal.
Today, the remaining 20 living hostages are finally set to be released, along with the bodies of another 28 who were either killed or died in captivity, and aid is due to flow back into a starving Gaza.
Some 1,200 Israelis were killed on 7 October 2023, with another 250 taken hostage. In the subsequent war, most of Gaza’s two million population has been displaced. More than 67,000 Gazans have been killed, according to Palestinian health officials.
Then, the signing ceremony is due to take place this afternoon in Sharm el Sheikh. It will be a momentous moment after a long and bloody war.

Humanitarian aid rolls into Gaza
The immediate focus for the UK and other nations will be to get aid into Gaza, with the UK committing £20m for water, sanitation and hygiene services for Gazans.
But the focus for the UK and other European allies is what happens after the hostages are released and Israel withdraws its troops.
What happens next is a much bigger and more complicated task: rebuilding Gaza; turning it into a terrorist-free zone; governing Gaza – the current plan is for a temporary apolitical committee; creating an international stabilisation force and all the tensions that could bring about – which troops each side would allow in; a commitment for Israel not to occupy or annex Gaza, even as Netanyahu makes plain his opposition to that plan.
The scale of the challenge is matched by the scale of devastation caused by this brutal war.
The prime minister will set out his ambition for the UK to play a leading role in the next phase of the peace plan.

Back home, the UK is hosting a three-day conference on Gaza’s recovery and reconstruction.
Last week, France hosted European diplomats and key figures from Middle Eastern countries, Egypt, Jordan, Saudi Arabia and Qatar – and later this week, the German chancellor is hoping to organise a conference on the reconstruction of Gaza with the Egyptians.
But in reality, European leaders know the key to phase two remains the key to phase one, and that’s Donald Trump.
As one UK figure put it to me over the weekend: “There is lots of praise, rightly, for the US president, who got this over the line, but the big challenge for us post-war is implementing the plan. Clearly, Arab partners are concerned the US will lose focus.”

The prime minister knows this and has made a point, at every point, to praise Mr Trump.
His cabinet minister Bridget Phillipson learned that diplomatic lesson the hard way yesterday when she was publicly lambasted by the US ambassador to Israel Mike Huckabee for suggesting to my colleague Trevor Phillips that the UK “had played a key role behind the scenes” and failed to mention Mr Trump by name.
“I assure you she is delusional,” tweeted Governor Huckabee. “She can thank @realDonaldTrump anytime just to set the record straight”.
Today, leaders will rightly be praising Mr Trump for securing the breakthrough to stop the fighting and get the remaining hostages home.

But this is only the beginning of a very long journey ahead to push through the rest of the 19-point plan and stop the region from falling back into conflict.
Britain has, I am told, been playing a role behind the scenes. The PM’s national security adviser Mr Powell was in Egypt last week and has been in daily touch with his US counterpart Steve Witkoff, according to government sources. Next week the King of Jordan will come to the UK.
Part of the UK’s task will be to get more involved, with the government and European partners keen to get further European representation on Trump’s temporary governance committee for Gaza, which Tony Blair (who was not recommended or endorsed by the UK) is on and Mr Trump will chair.
The committee will include other heads of states and members, including qualified Palestinians and international experts.
As for the former prime minister’s involvement, there hasn’t been an overt ringing endorsement from the UK government.
It’s helpful to have Mr Blair at the table because he can communicate back to the current government, but equally, as one diplomatic source put it to me: “While a lot of people in the Middle East acknowledge his experience, expertise and contact book, they don’t like him and we need – sooner rather than later – other names included that Gulf partners can get behind.”
Today it will be the US, Egypt, Qatar and Turkey that sign off on the peace plan they directly negotiated, as other Middle Eastern and European leaders, who have flown into Sharm el Sheikh to bear witness, look on.
But in the coming days and weeks, there will need to be a big international effort, led by Mr Trump, not just to secure the peace, but to keep it.
The world turns to the Middle East as hostages held by Hamas are returned to their families in Israel on Monday after over two years in captivity.
Thousands of Palestinian prisoners will also be released from Israeli prisons in exchange.
Mark Stone is in Sharm el Sheikh, Egypt, and Dominic Waghorn is in Jerusalem, Israel, as President Trump flies first to Israel to speak at the Israeli Parliament and celebrate the return of the hostages, before he flies to the Sinai Peninsula.
Dozens of world leaders will follow him to Sharm el Sheikh to witness a peace summit that many hope is the start of true peace in the Middle East.
