Helps customers understand whats in the products they buy. Charlotte gallagher reports. Were used to seeing these traffic light labels on much of the food and drink we buy. They allow us to see at a glance how much fat, saturates, sugar and salt a product contains. But the labels, introduced by the department of health in 2015, are voluntary. The local Government Association says only around two thirds of products sold in the uk currently have them. The European Union currently regulates food labelling and the lga has called on ministers to make the traffic light scheme a legal requirement once eu legislation are transferred into british law. It says the scheme is popular with consumers and helps them make informed choices about what they are eating and drinking. They believe making the labels mandatory would help tackle the britains obesity crisis. The department of health says its committed to giving people clear information about what they eat and will continue to help consumers to make healthy choices. Charlotte gallagher, bbc news. Now on bbc news, our world. For nearly a0 years, afghanistan has been in a constant state of war. How has this affected the Mental Health of its people . Afghanistan has been at war for nearly a0 years. A conflict that has claimed over two million civilian lives. They are from 40, 50 years ago and itjust really shows how long war has been going on in this country. And the cost to the nations Mental Health has been enormous. Its estimated that three quarters of afghan women and more than half the men sufferfrom Mental Health problems. With rare access to the countrys only secure psychiatric unit and one of the largest hospitals, i meet the medical staff trying to deal with the Mental Health emergency. And the patients traumatised by decades of conflict. Herat, in western afghanistan, is the countrys Third Largest city. As war continues in much of the country, the demand for Mental Healthcare is also sky rocketing. This is the psychiatric unit in the citys main hospital. Ive come to meet dr Wahid Noorzad who, at 33, is the man in charge. Azata is 14 years old and has been brought in by her mother. Like many other young afghans, traumatic events have been a big part of azatas childhood. Dr noorzad suspects that azata is suffering from ptsd post Traumatic Stress disorder a type of anxiety disorder triggered by traumatic events, often seen in soldiers. Ptsd is increasingly common amongst afg hanistans war ravaged population. Social taboos around Mental Health make it difficult to get patients through the door, and thats why dr noorzad takes every opportunity to reach out to the public. At a local herati tv station, dr noorzad is being interviewed. Hes a regular guest and gives Mental Health advice to people who call in. Dr noorzad holds a weekly Outreach Programme an opportunity for more people to get help. Its free and has been running forfour years. Farad is a trained counsellor and a volunteer who runs the sessions. Farad himself suffers from ptsd and is also a patient of dr noorzad, but, unlike the majority of afghans suffering ptsd, hes seeking professional psychological help. A very recent traumatic event led to farad getting ptsd. 0n the ist of august 2017, two men walked into the jawadia mosque and opened fired on 300 worshippers gathered for evening prayers. They then detonated their suicide vests, killing 38, including farads teenager brother, hossein. Dozens of others were injured. Jawadia is a shia mosque, and thats why it was targeted. Sunni militants like isis and the taliban regard the shia as heretics. Farad comes here every day. For him, the trauma of the attack is still very raw. Photographs of the 38 victims, some as young as two years old. All are given the title shaheed, meaning martyr. Crying. Ghulam haider sobhani has been the imam of this mosque for the last 25 years. He was also here on the day of the attack. Speaking to the imam, the challenge faced by dr noorzad and his team becomes clear. The taboo around Mental Health is rooted deep within the culture. For many afghans, war and violence have been a constant presence. More than two million civilians have been killed since the soviet Union Invaded the country in 1979. Herat even has its own Museum Dedicated to war. These are really old, mostly russian weapons and ammunitions and they are from 40, 50 years ago and itjust really shows how long war has been going on in this country. I mean, we hearfour decades, but seeing these really makes it more tangible. The soviets withdrawal in 1989 was the start of a 10 year long civil war. This led to the rise of the taliban, who continue their bloody insurgency to this day, funded by a booming opium trade. 2017 saw a bumper opium poppy crop in afghanistan. Perhaps as a form of self medication for the trauma of war, many afghans use opium. An estimated 10 of the population is now addicted to the opium poppy derivative, heroin. Some of these addicts end up here, at the countrys only secure psychiatric unit. Its home to about 250 men and 50 women, many of whom are suffering from drug induced schizophrenia and psychosis. Mohammed essar is a former member of the taliban. Mohammed davood is a former member of the mujahideen. Both men were drug addicts and suffer from ptsd and were sent here by their families. Without a resident psychiatrist, the unit relies on outside help. Dr saljoochi is the visiting psychiatrist. Many patients families have left for neighbouring countries because of war and cannot be contacted. Jaffar is here because of depression and schizophrenia. This led to an out of control drug habit and later to violence. Like so many other patients here, jaffar is well enough to go home, but hes not sure when he can leave. Through a locked metal gate is the female section. About 50 women live here, some with their children. Some have been here for years and look likely to stay. A couple of days later, ive come back to the psychiatric unit because ive heard some news about jaffar. Back at herats main hospital, azata, the 14 year old we met earlier, who was diagnosed with ptsd, is back to see dr noorzad for her first follow up appointment. Back at herats main hospital, azata, the 14 year old we met earlier, who was diagnosed with ptsd, is back to see dr noorzad for her first follow up appointment. For azata, the long journey to recovery is just beginning and shes lucky to have her familys support. For azata, the long journey to recovery is just beginning and shes lucky to have her familys support. For farad, the volunteer counsellor who we met working with dr noorzad, recovery from his ptsd seems a long way away. The trauma that took his brother away is still too recent and raw. Farads recovery is being aided by the treatment and friendship of dr noorzad. At the local football stadium weve all come to watch a game together. Seeing these players run around today, its easy to forget this stadiums dark past, an execution ground during the reign of the taliban. Seeing the scale of the problem, its hard to imagine how and when the country will heal, but there is hope. The effects of recent decades of war on peoples Mental Health is being recognised and some help given, and its clear that many afghans are determined that they and their country will overcome the trauma of war. Hello there. It looks like sundays going to be a brighter day than certainly what we had on saturday all that cloud and rain. But it will be a cold certainly colder than saturday. The Gale Force Winds easing down in the morning. Then we should see sunshine and wintry showers for many areas with snow, even falling down to lower levels as well. This is the deep area of low pressure which will bring these strong winds during the overnight period. And as we head into sunday morning, those gales will be easing from eastern areas. But its going to be a blustery day with wintry showers piling into the northern and western areas. The gales easing away from the east areas, like i mentioned, but still quite a blustery day. Its going to feel cold. There will be plenty of sunshine around southern and central and eastern areas but i think into the afternoon, even a few wintry showers reaching the midlands, maybe into the south east of england as well, but certainly very windy in the north of scotland with snowfall accumulations continuing to mount up. Its going to be a cold day. As we head on in towards sunday night, much of the same, really. With further wintry showers or even longer spells of snow across the north and the west of the country and its going to be a cold night. Subzero values central northern areas, so there will be a risk of ice to watch out for first thing on monday morning. But actually, monday is not looking too bad. Therell be plenty of sunshine around. In fact, more sunshine than what well see on sunday. A few wintry showers across northern and western areas. The wind beginning to pick up here towards the end of the day ahead of the next weather front which will be moving in off the atlantic. Another chilly day. Temperatures five to around eight degrees. Now, as we head through monday night into tuesday, this weather front will push its way eastwards across the country, encountering that cold air, so it looks like we could see some considerable snow on its leading edge, certainly across northern areas. Over the pennines, central southern scotland could see quite a lot of snow as this weather front moves through. Eventually, it clears through as we go through the course of tuesday with skies brightening up behind, but we will see further wintry showers moving into scotland and northern ireland. And those temperatures again chilly 4 6 celsius. A brief ridge of High Pressure calms things down as we head on in towards wednesday. The next weather system moves in off the atlantic, and its a repeat performance once again. It bumps into that cold air, we could see disruptive some snow across the northern half of the country. 10cm to maybe 20cm of snow over the Higher Ground of scotland, in fact, and even snow down to lower levels. Further south, it will be mainly of rain. But its going to be quite a messy day, i think, on wednesday. Maybe something a little less cold across the south but its still going to feel on the chilly side. As we head on through the rest of the week, thursday and friday looks much of the same on the chilly side. Welcome to bbc news, broadcasting to viewers in north america and around the globe.
