0:01:28 > 0:01:31Hello and welcome to World News Today.
0:01:31 > 0:01:34After last week's school shooting in Florida in which 17 people
0:01:34 > 0:01:37were killed, President Trump has called for some teachers to carry
0:01:37 > 0:01:39concealed weapons in schools.
0:01:39 > 0:01:42He was speaking to the Conservative Political Action Conference.
0:01:42 > 0:01:46Maybe 10% or 20% of the population of teachers, etc.
0:01:46 > 0:01:50It's not all of them, but you would have a lot,
0:01:50 > 0:01:54and you would tell people that they are inside.
0:01:54 > 0:01:56And the beauty it's concealed.
0:01:56 > 0:01:59No-one would ever see it unless they needed it.
0:01:59 > 0:02:03It's concealed, so this crazy man who walked in wouldn't even know
0:02:03 > 0:02:05who it is that has it.
0:02:05 > 0:02:06That's good.
0:02:06 > 0:02:08That's not bad, that's good.
0:02:08 > 0:02:11And the teacher would have shot the hell out of him before
0:02:11 > 0:02:12he knew what happened.
0:02:12 > 0:02:20CHEERING AND APPLAUSE
0:02:26 > 0:02:28They love their students.
0:02:28 > 0:02:36They love those students, folks, remember that.
0:02:36 > 0:02:43Donald Trump there. Let's go live to Maryland at the conference. Tell us
0:02:43 > 0:02:46a bit more about what President Trump said and what the reaction has
0:02:46 > 0:02:49been. In terms of
0:02:49 > 0:02:52been. In terms of the shooting, you had
0:02:52 > 0:02:57the vital that there is that went down pretty well with this audience.
0:02:57 > 0:03:01I wouldn't say they were overwhelmed with the idea of arming teachers but
0:03:01 > 0:03:07they certainly liked highs robust support for the second in general.
0:03:07 > 0:03:12But the amendment that Americans use to protect their right to own guns
0:03:12 > 0:03:16and weapons more generally. Interestingly, highs idea about
0:03:16 > 0:03:20arming teachers has not exactly gone down well with some teaching unions
0:03:20 > 0:03:26but also the governor of Florida, a Republican. He is not too keen on
0:03:26 > 0:03:31that either, he proposing raising the age at which you can buy an
0:03:31 > 0:03:39assault weapon in Florida to the age of 21, which of course would have
0:03:39 > 0:03:45prevented the killer with getting the weapon he used last week. But
0:03:45 > 0:03:51the debate is on this teacher arming business and I think that will
0:03:51 > 0:03:55divide people significantly because only one hand, Donald Trump says it
0:03:55 > 0:03:59will make schools safer and on the other, then people will say the last
0:03:59 > 0:04:05thing America needs to combat a gun problem is more guns.
0:04:05 > 0:04:11And if I can just turn to one other piece of news that were just getting
0:04:11 > 0:04:15in on the news agencies, the United States will apparently open a new
0:04:15 > 0:04:19embassy injuries of an inmate to coincide with Israel's 70th
0:04:19 > 0:04:23anniversary. We knew this move was coming but confirmation now of the
0:04:23 > 0:04:30timing. That is interesting and Donald Trump
0:04:30 > 0:04:33referred to Jerusalem this morning in highs speech and the moving of
0:04:33 > 0:04:40the embassy there and that got an enormous cheer. It's surprising that
0:04:40 > 0:04:45they are doing it quite so quickly because obviously they will have to
0:04:45 > 0:04:49be some pretty heavy security arrangements for that building
0:04:49 > 0:04:54injuries along. I think they do have a culture that there are already so
0:04:54 > 0:05:03that might be partly it. He will stay fulfilling a campaign promise,
0:05:03 > 0:05:06there will be many people in the republican movement, particularly
0:05:06 > 0:05:12the Christian Right, who will welcome this enormously, but in
0:05:12 > 0:05:14European capitals and in other parts of the world where they have been
0:05:14 > 0:05:20dry for years to help edge on some sort of peace process, there will be
0:05:20 > 0:05:26a lot of anxiety about this move. A lot of America's allies do not
0:05:26 > 0:05:30support the idea and of course, the Palestinians are utterly opposed to
0:05:30 > 0:05:35it in its current form. It is going to cause a row, there's no doubt
0:05:35 > 0:05:41about that. Just to let you know that it is
0:05:41 > 0:05:48reported the building will be moving to a separate annex by the end of
0:05:48 > 0:05:542019. It is a permanent embassy, according to Reuters. We will
0:05:54 > 0:05:56confirm that as soon as we can.
0:05:56 > 0:06:00The United Nations Security Council is due to vote in the next hour
0:06:00 > 0:06:01on a draft resolution calling for a humanitarian
0:06:01 > 0:06:02ceasefire in Syria.
0:06:02 > 0:06:05So far, Russia has blocked attempts to impose a 30-day nationwide truce.
0:06:05 > 0:06:08Almost 400,000 people are trapped in Eastern Ghouta and under
0:06:08 > 0:06:12constant bombardment by President Assad's forces.
0:06:12 > 0:06:14The rebel-held area is on the outskirts of the capital,
0:06:14 > 0:06:17and has been under Government siege since 2013.
0:06:17 > 0:06:21Opposition activists accuse Assad's forces of killing about 400 people
0:06:21 > 0:06:24in six days of attacks.
0:06:24 > 0:06:28The UN is warning of a massacre.
0:06:28 > 0:06:31Martin Patience reports from neighbouring Lebanon.
0:06:31 > 0:06:35Another frantic search for survivors.
0:06:35 > 0:06:42An airstrike has just hit.
0:06:44 > 0:06:47A child is brought out of the burning building.
0:06:47 > 0:06:51But a woman is trapped inside.
0:06:51 > 0:06:56They're struggling to find her.
0:06:56 > 0:06:58Come down, come down, they shout.
0:06:58 > 0:07:04They've found her.
0:07:04 > 0:07:09In another home, another rescue.
0:07:09 > 0:07:17But for the dead, there is no peace here.
0:07:18 > 0:07:26Even those burying a victim are running for cover.
0:07:28 > 0:07:31More than a million Syrians have fled over the mountains
0:07:31 > 0:07:35into neighbouring Lebanon.
0:07:35 > 0:07:38We spoke to one couple from eastern Ghouta.
0:07:38 > 0:07:42He and his wife didn't want their faces shown,
0:07:42 > 0:07:48fearing reprisals from the Syrian Government.
0:07:48 > 0:07:52TRANSLATION:I last spoke to my cousin three days ago.
0:07:52 > 0:07:53It was terrible.
0:07:53 > 0:07:57He told me that they were waiting to die.
0:07:57 > 0:08:00He asked me to forgive him if I never heard from him again.
0:08:00 > 0:08:03His little boy was killed.
0:08:03 > 0:08:05He was just three and a half.
0:08:05 > 0:08:10I have not heard from my cousin since.
0:08:10 > 0:08:18He plays me the last message he got from his cousin.
0:08:19 > 0:08:23They are destroying Ghouta, he says.
0:08:23 > 0:08:31Please pray for us.
0:08:33 > 0:08:36Let's take a look at some of the other stories making the news.
0:08:36 > 0:08:40There have been two large explosions in the Somali capital Mogadishu,
0:08:40 > 0:08:41killing 18 people and injuring 20.
0:08:41 > 0:08:44The police say a suicide bomber blew up a car near the presidential
0:08:44 > 0:08:47palace and a second blast was close to the national intelligence agency.
0:08:47 > 0:08:54Both were followed by heavy gunfire.
0:08:57 > 0:09:04A former adviser to Donald Trump's is expected to plead guilty today.
0:09:04 > 0:09:09He is said to be co-op rating with the investigation and could further
0:09:09 > 0:09:14implicate members of Tron's 2016 election campaign team. Complaints
0:09:14 > 0:09:19were filed on Thursday.
0:09:19 > 0:09:22A painting by the French artist Edgar Degas, which was stolen
0:09:22 > 0:09:25from a museum in Marseille in 2009, has been found on a bus
0:09:25 > 0:09:27near Paris.The artwork was discovered in the luggage
0:09:27 > 0:09:29compartment of the vehicle at a motorway service station.
0:09:29 > 0:09:31Experts confirmed that it's "The Chorus Singers" -
0:09:31 > 0:09:37a pastel painting said to be worth nearly a million dollars.
0:09:37 > 0:09:40The man who exposed the Russian doping scandal has given his first
0:09:40 > 0:09:41international broadcast interview to the BBC.
0:09:41 > 0:09:45Evidence from whistle-blower Dr Grigory Rodchenkov
0:09:45 > 0:09:48on state-sponsored doping saw Russia banned from the Winter Olympics -
0:09:48 > 0:09:51and the fallout from the testimony forced him into hiding and in fear
0:09:51 > 0:09:52of his life.
0:09:52 > 0:09:56Now living in the United States, we interviewed Dr Rodchenkov
0:09:56 > 0:09:59from a secret location where he said if he hadn't fled
0:09:59 > 0:10:00Russia he'd now be dead.
0:10:00 > 0:10:02Two Russian athletes at the winter olympics have tested
0:10:02 > 0:10:05positive for doping.
0:10:05 > 0:10:10This exclusive report is by our sports editor, Dan Roan.
0:10:10 > 0:10:12It is one of sport's greatest scandals.
0:10:12 > 0:10:17Russian cheating reached its height at the last Winter Games in Sochi.
0:10:17 > 0:10:20The mastermind, Dr Grigory Rodchenkov.
0:10:20 > 0:10:22In 2015, the former head of Moscow's anti-doping lab
0:10:22 > 0:10:25turned whistle-blower, fleeing to the west.
0:10:25 > 0:10:28Ever since, he's been in FBI witness protection.
0:10:28 > 0:10:30But we are on the way to meet him.
0:10:30 > 0:10:33For more than two years now, the man at the very heart
0:10:33 > 0:10:36of Russia's doping scandal has been living in hiding here somewhere
0:10:36 > 0:10:38in the United States.
0:10:38 > 0:10:42Finally, he's agreed to speak to us, but such are the security concerns
0:10:42 > 0:10:47surrounding him we've not even been told where we have to go.
0:10:47 > 0:10:49After hours on the road, we are taken to a location
0:10:49 > 0:10:52that we are told has to remain a secret along with
0:10:52 > 0:10:54Rodchenkov's new identity.
0:10:54 > 0:11:02If you had not left Russia, where would you be now?
0:11:03 > 0:11:07You'd be dead.
0:11:07 > 0:11:08I would be done.
0:11:08 > 0:11:10Rodchenkov's role in Russia's remarkable doping programme
0:11:10 > 0:11:12became the subject of an Oscar-nominated film.
0:11:12 > 0:11:17Were you the mastermind that cheated the Olympics?
0:11:17 > 0:11:18Yes.
0:11:18 > 0:11:20Yes.
0:11:20 > 0:11:22He said the conspiracy went right to the top and that
0:11:22 > 0:11:23London 2012 was also targeted.
0:11:23 > 0:11:29So what does he say to British athletes whose Games were tainted?
0:11:29 > 0:11:34I am very sorry that your career, your biography was simply broken
0:11:34 > 0:11:37because of the systematic and widespread cheating that was
0:11:37 > 0:11:43practised in the Russian national team before the London Games. That's
0:11:43 > 0:11:45why I'm sitting here and telling you the truth about what happened at
0:11:45 > 0:11:47that time.
0:11:47 > 0:11:48The Russian Government says you are lying.
0:11:48 > 0:11:49You were cheating.
0:11:49 > 0:11:54It wasn't them, it was you.
0:11:54 > 0:12:00Russia is a country and lighting and denying, especially in sport. I give
0:12:00 > 0:12:00you only truth.
0:12:00 > 0:12:02I give you only truth.
0:12:02 > 0:12:09Does British sport have a problem with cheating, do you think?
0:12:09 > 0:12:19Honestly? Yes. I have some, several extremely suspicious cases in
0:12:19 > 0:12:20British sport.
0:12:20 > 0:12:22Despite Russian claims he is part of a western conspiracy,
0:12:22 > 0:12:24Rodchenkov's information led to a ban from the Winter Olympics.
0:12:24 > 0:12:27168 of the country's athletes competed as neutrals but they may
0:12:27 > 0:12:29now be allowed to march under their national flag
0:12:29 > 0:12:37at the closing ceremony.
0:12:45 > 0:12:47The Olympic Athletes of Russia team.
0:12:47 > 0:12:49Only clean Russians were meant to be in Pyeongchang,
0:12:49 > 0:12:51but today a second of its athletes
0:12:51 > 0:12:53at these Games, Nadezhda Sergeeva, failed a drugs test.
0:12:53 > 0:13:01Moving forward from sport's biggest crisis is no easy task.
0:13:01 > 0:13:04The World Health Organization has told the BBC it's investigating
0:13:04 > 0:13:11a number of harassment claims within the agency.
0:13:11 > 0:13:14Dr Tedros Adhanom Ghebreyesus says the recent revelations around abuse
0:13:14 > 0:13:17and harassment within aid agencies are "shocking" but that there should
0:13:17 > 0:13:19be a "measured response".
0:13:19 > 0:13:22He's been speaking to our global health correspondent Tulip Mazumdar
0:13:22 > 0:13:25at a Patient Safety Summit in London.
0:13:25 > 0:13:27We're here at the Global Patient Safety Summit where health leaders
0:13:27 > 0:13:30have been meeting to discuss how to cut the avoidable deaths
0:13:30 > 0:13:32due to medical errors all around the world.
0:13:32 > 0:13:40Speaking on the stage earlier was the relatively new head
0:13:41 > 0:13:44of the World health Organisation, Tedros Ghebreyesus, and I've been
0:13:44 > 0:13:48speaking to him about the current controversy engulfing
0:13:48 > 0:13:49the aid sector.
0:13:49 > 0:13:51How have you found these revelations yourself personally?
0:13:51 > 0:13:53It has been so shocking, hearing what's been going on.
0:13:53 > 0:13:56Of course it has.
0:13:56 > 0:13:57It's very shocking.
0:13:57 > 0:14:01But at the same time, it should strengthen our resolve to fight it.
0:14:01 > 0:14:04Clearly this is something that has got people very upset as people
0:14:04 > 0:14:12are already withdrawing money from Oxfam and others.
0:14:12 > 0:14:15they are so keen to what you do on the ground,
0:14:15 > 0:14:17are you worried that this is going to impact what
0:14:17 > 0:14:18you can do for people?
0:14:18 > 0:14:21As long as we start instituting radical measures to address it
0:14:21 > 0:14:23in the future, I think we have to see
0:14:23 > 0:14:24the other side also.
0:14:24 > 0:14:30Oxfam, for instance, has done great things.
0:14:30 > 0:14:33I know it myself, I'm from a developing country
0:14:33 > 0:14:35and I can give you many examples where Oxfam have really done
0:14:35 > 0:14:39incredible things to help the needy.
0:14:39 > 0:14:41That is why this is so troubling, isn't it?
0:14:41 > 0:14:44Because that trust that was there has now been damaged
0:14:44 > 0:14:50possibly without being able to recover from that.
0:14:50 > 0:14:53We have to see the problem properly and address it in a way
0:14:53 > 0:14:56that we continue to do the good things.
0:14:56 > 0:14:59So there should be a balance.
0:14:59 > 0:15:05And just to be clear, are you doing a review
0:15:05 > 0:15:08into WHO practices to make sure that your staff are following strict
0:15:08 > 0:15:12guidelines and protecting vulnerable people on the ground?
0:15:12 > 0:15:15That's what I said we have been doing and there is always
0:15:15 > 0:15:16room for improvement.
0:15:16 > 0:15:22We identified, even last week when we checked the policy issues,
0:15:22 > 0:15:24there are some things that we need to improve.
0:15:24 > 0:15:25The most important thing is commitment
0:15:25 > 0:15:28to continuous improvement.
0:15:28 > 0:15:30Make it an open organisation, transparent one, prevent
0:15:30 > 0:15:38things from happening, that's the most important thing.
0:15:39 > 0:15:42But detect as something wrong happens and take a serious measure.
0:15:42 > 0:15:45We are doing things differently, as I told you.
0:15:45 > 0:15:48For instance, for the first time in WHO, the top management,
0:15:48 > 0:15:5264% of the top management are women.
0:15:52 > 0:16:00Are you investigating any complaint against WHO staff at the moment?
0:16:01 > 0:16:03Of course there are cases that came from 2017
0:16:03 > 0:16:06which are under investigation.
0:16:06 > 0:16:09Most of them are harassment, sexual, I think one place
0:16:09 > 0:16:10which is still under investigation.
0:16:10 > 0:16:13The most important thing, I said earlier, is to
0:16:13 > 0:16:17have an open organisation and to focus on prevention.
0:16:17 > 0:16:20And also to have mechanisms for early detection and ways
0:16:20 > 0:16:28to protect whistle-blowers, which we have.
0:16:34 > 0:16:36The Nigerian president, Muhammadu Buhari, has described
0:16:36 > 0:16:38the suspected kidnapping of schoolgirls by Boko Haram
0:16:38 > 0:16:40jihadists four days ago as a national disaster.
0:16:40 > 0:16:43He said more troops had been sent to the town of Dapchi
0:16:43 > 0:16:45to try to bring them to safety.
0:16:45 > 0:16:47It is still not clear how many students were taken,
0:16:47 > 0:16:50but there are fears that it could be as many as 100.
0:16:50 > 0:16:54Nigeria's Information Minister, Lai Mohammed, said Boko Haram
0:16:54 > 0:17:01was just trying to make the Nigerian government look bad.
0:17:01 > 0:17:05Until students show, all we hear from their parents that
0:17:05 > 0:17:08they are with them, we cannot say this is a number
0:17:08 > 0:17:09of students we have.
0:17:09 > 0:17:11Give us a few more days please.
0:17:11 > 0:17:15These are the dying days of Boko Haram.
0:17:15 > 0:17:20However they tend to do is to embarrass government.
0:17:20 > 0:17:22Their power has gone completely.
0:17:22 > 0:17:30Their oxygen is publicity.
0:17:34 > 0:17:41We are going to go about our top story, the vote and so a ceasefire
0:17:41 > 0:17:49in Syria. What do we know about the prospect of agreement?
0:17:50 > 0:17:54prospect of agreement?The mood in the building is that it seems as
0:17:54 > 0:18:00though leaders are close. The Kuwaiti embarrasses they are close
0:18:00 > 0:18:05to an agreement. We have also heard from leaders overseas saying the
0:18:05 > 0:18:11same thing so it seems we may have a vote in favour of a draft resolution
0:18:11 > 0:18:16on that ceasefire. This has been a two-week long negotiation process.
0:18:16 > 0:18:21It has been a long road to get the parties together. First Russia said
0:18:21 > 0:18:25the draft was unrealistic and they needed more guarantees that the
0:18:25 > 0:18:29rebels would abide by it and you have accusations from the likes of
0:18:29 > 0:18:37the United States who said they were delaying for Assad to continue highs
0:18:37 > 0:18:40military operation. But there is a desperate need for the ceasefire to
0:18:40 > 0:18:45provide relief to the civilians who are there and need aid and to get
0:18:45 > 0:18:50out, to seek medical attention, and they may have that ceasefire today.
0:18:50 > 0:18:55And how have they managed a potentially bring Russia on size
0:18:55 > 0:19:00given President Assad has said he is fighting some jihadi groups?That
0:19:00 > 0:19:05was the kind of key proposal that was wrapped into the Swedish and
0:19:05 > 0:19:11Kuwaiti draft resolution, that RSS, Al-Qaeda and even their associates
0:19:11 > 0:19:19would not be included in the ceasefire.
0:19:19 > 0:19:22ceasefire. -- Isis. The Russians offered several other types of
0:19:22 > 0:19:27amendments that weren't included in the draft and diplomats say they
0:19:27 > 0:19:32still feel it is true to the original goals that the and Kuwaiti
0:19:32 > 0:19:39people put forward. This has been a two-week long process, though the
0:19:39 > 0:19:42vote has been delayed several times for last-minute negotiations and it
0:19:42 > 0:19:45seems they are willing to meet Russia halfway to get a positive
0:19:45 > 0:19:54thought.Thanks very much. In the last few minutes, the president of
0:19:54 > 0:19:57the European Council
0:19:58 > 0:20:00In the last few minutes, the president of the European
0:20:00 > 0:20:02Council, Donald Tusk, has told reporters in Brussels that
0:20:02 > 0:20:04London's position on Brexit is based on 'pure illusion'.
0:20:04 > 0:20:07He made the comment at the end of a meeting of leaders
0:20:07 > 0:20:09from 27 EU countries, excluding Britain.
0:20:09 > 0:20:12One of the topics discussed at that meeting was the bloc's joint stance
0:20:12 > 0:20:13on ties with Britain after Brexit.
0:20:13 > 0:20:19if the media reports are correct, I am afraid that the UK's position
0:20:19 > 0:20:27today is based on pure delusion.It looks like the cake philosophy is
0:20:27 > 0:20:34still alive. From the very start, it has been a key principle of the EU
0:20:34 > 0:20:3927 that there can be no cherry picking and now single market a la
0:20:39 > 0:20:45carte. This will continue to be a key principle, I have no doubt.
0:20:45 > 0:20:49Let's speak to our correspondent in Brussels, Adam Fleming.
0:20:49 > 0:20:53How significant is this intervention?I think the first
0:20:53 > 0:20:59thing to say is that he'll was responding to reports of what the
0:20:59 > 0:21:04British Government agreed as an eight or log meeting of the Cabinet.
0:21:04 > 0:21:08He doesn't know the British position in detail. He will not know that
0:21:08 > 0:21:16until he meets Theresa May in London and he wants no until their Prime
0:21:16 > 0:21:24Minister gives a speech detailing it on Friday. But I think that was
0:21:25 > 0:21:27on Friday. But I think that was a pretty brutal put-down. When he
0:21:27 > 0:21:31talks about the cake philosophy, he is talking about the idea that the
0:21:31 > 0:21:36EU has had all along, which is that the UK cannot just pick bits of the
0:21:36 > 0:21:39single market to stay in and leave others to decide, it can't pick
0:21:39 > 0:21:45which EU lows at once to follow and then write its own lows for the
0:21:45 > 0:21:50likes, which is the Brexit policy of the EU and has been since last year
0:21:50 > 0:21:54when talks started. And the way he delivered the words as well, he
0:21:54 > 0:21:58seems pretty glum. I wouldn't say he was angry, but he was verging on
0:21:58 > 0:22:02anger. I think this will be doubly annoying for the British Government
0:22:02 > 0:22:07because they think the big meeting they had yesterday, with the Cabinet
0:22:07 > 0:22:11who some of whom have different views on Brexit, they think that
0:22:11 > 0:22:15went very well, so I think those comments from Donald Tusk will have
0:22:15 > 0:22:23gone down very badly in London tonight. This final meeting of the
0:22:23 > 0:22:2727 leaders of the EU was meant to be about Brexits, Donald Tusk has just
0:22:27 > 0:22:30ensured that all the headlines tomorrow about the meeting will be a
0:22:30 > 0:22:35secular but Brexit.Given as you say we don't know what the British
0:22:35 > 0:22:40Government position is, what do we think the agreement was on the
0:22:40 > 0:22:45question of Common Market, single market access?The phrase that is
0:22:45 > 0:22:49doing the rounds at the moment is, wait for it, ambitious, manage
0:22:49 > 0:22:55divergences. I'm not entirely sure what it means but I think what the
0:22:55 > 0:22:58concepts are is that you have a really close economic relationship
0:22:58 > 0:23:04between the UK and the EU where the UK starts off following most of the
0:23:04 > 0:23:10EU's rolls and then over time moves away from those roles. In some ways,
0:23:10 > 0:23:13quite dramatically but you manage it so that both sides manage how the
0:23:13 > 0:23:23divergence happens to prevent any problems. The Irish Taoiseach said
0:23:23 > 0:23:26that it sounds like choosing which parts of the single market you want
0:23:26 > 0:23:31and which you want to reject, which I was seeing, is one of the EU has
0:23:31 > 0:23:35said is not possible all along.An interesting weekend. Thanks very
0:23:35 > 0:23:38much.
0:23:38 > 0:23:41Did you know that some fruit, fruit teas and snacking between meals can
0:23:41 > 0:23:43increase your chances of tooth erosion?
0:23:43 > 0:23:46Scientists at King's College London found acidic food and drink
0:23:46 > 0:23:50can wear teeth down - especially if you snack continually.
0:23:50 > 0:23:53The way we eat and drink is almost as much of a factor in tooth
0:23:53 > 0:23:55erosion as what we consume, according to new research.
0:23:55 > 0:23:57Here's more from our health correspondent, Catherine Burns.
0:23:57 > 0:23:59Just going to have a look...
0:23:59 > 0:24:01Back in the dentist chair even though she thought she looked
0:24:01 > 0:24:03after her teeth well.
0:24:03 > 0:24:05Rachel has erosive tooth wear.
0:24:05 > 0:24:09It is when acid eats away at them until they chip or get shorter.
0:24:09 > 0:24:12It turns out Rachel has a bad habit she didn't even know about.
0:24:12 > 0:24:16When I drink normally, especially if it's a kind of flavoured drink,
0:24:16 > 0:24:20I just hold it in my mouth a bit longer than the average person.
0:24:20 > 0:24:23I think it might be the taste or something like that.
0:24:23 > 0:24:27I think again, that exposure to my teeth and sitting in my mouth
0:24:27 > 0:24:30longer than just swallowing it down.
0:24:30 > 0:24:34As vices go, it doesn't sound so terrible.
0:24:34 > 0:24:37But researchers say it's bad news for your teeth.
0:24:37 > 0:24:41About one in six people we found her habits like sitting
0:24:41 > 0:24:44things really slowly or switching the amount their mouths,
0:24:44 > 0:24:49people tend to rinse things around their mouths,
0:24:49 > 0:24:51if you're doing these behaviours on a daily basis
0:24:51 > 0:24:53for years and years, you can cause serious
0:24:53 > 0:24:54damage to your teeth.
0:24:54 > 0:24:56And that serious damage can mean that your whole mouth
0:24:56 > 0:24:57needs to be rebuilt.
0:24:57 > 0:25:01It is preventable, mostly by cutting back on acidic food and drink.
0:25:01 > 0:25:03Some things, though, like fruit, are generally seen
0:25:03 > 0:25:05as the healthy option.
0:25:05 > 0:25:11But from a dental point of view, they can erode teeth.
0:25:11 > 0:25:14This report mentions things like adding a slice of lemon
0:25:14 > 0:25:16or lime to your water, sugar free soft drinks,
0:25:16 > 0:25:21drinking fruit teas and snacking on fruit.
0:25:21 > 0:25:24Take these grapes for example, if you were to eat ten or 20
0:25:24 > 0:25:26of them in one sitting, that would be one acid
0:25:26 > 0:25:27attack on your teeth.
0:25:27 > 0:25:31If you were to eat the same amount on a longer period of time,
0:25:31 > 0:25:32it would be a sustained attack.
0:25:32 > 0:25:39So should people scrap their five a day to protect their teeth?
0:25:39 > 0:25:41The researchers say that's the last thing they want.
0:25:41 > 0:25:44But the advice is to be aware of overall eating patterns
0:25:44 > 0:25:50and to consider snacks that are less acidic and high in calcium.
0:25:50 > 0:25:51You can reach me on Twitter.
0:25:51 > 0:25:55I'm @geetagurumurthy.
0:25:55 > 0:26:04Thanks for watching.
