MINUTE OF EXERCISE A DAY COULD PREVENT OSTEOPOROSIS, FINDS STUDY

No more excuses

Many people think that getting fit means devoting your life to the gym and slogging it out for hours. And unsurprisingly, that can be pretty off-putting.

But increasingly we’re realising that short workouts can be much more effective than long ones, if you just know what to do.

It turns out that just a minute’s exercise a day can have a hugely beneficial impact on your health.

According to a study by the Universities of Exeter and Leicester, women who do 60-120 seconds of high-intensity weight-bearing exercise a day have four per cent better bone density than those who do less than a minute.

Women who exercise for over two minutes have even stronger bones, with density six per cent higher than those who do under a minute.

After the age of 30, people tend to lose more bone mass than they gain, and the higher your bone density, the lower your likelihood of developing osteoporosis.

You’re also less likely to have bone fractures in old age.

The study was conducted on over 2,500 female participants, and it’s women who are most at risk of osteoporosis, with bone density declining significantly after the menopause.

According to the International Osteoporosis Foundation, a tenth of women aged 60 are affected by osteoporosis, and this rises to two-thirds of women aged 90.

What’s more, one in three women over the age of 50 and one in five men of the same age will suffer from osteoporotic fractures.

But further research needs to be done to work out how best one should undertake exercise in order to improve bone density the most.

“We don’t yet know whether it’s better to accumulate this small amount of exercise in bits throughout each day or all at once, and also whether a slightly longer bout of exercise on one or two days per week is just as good as one to two minutes a day,” said lead author Dr Victoria Stiles.

“But there’s a clear link between this kind of high-intensity, weight-bearing exercise and better bone health in women.”

To reach their conclusions, the researchers asked their participants to wear activity monitors for a week and then compared this data to measurements of their bone health.

The activity data was broken down into single seconds to understand how people move in their daily lives.

“We wanted to make every second count in our analysis, because short snippets of high-intensity activity are more beneficial to bone health than longer, continuous periods,” Stiles said.

“We were careful not to ignore short bursts of activity throughout the day.”

Many people, although not consciously exercising, engage in non-exercise activity thermogenesis – or NEAT – over the course of the day, and this can be enough to improve your health.

If you want to increase your bone health, start with simply trying to walk more, and from there you can incorporate short bouts of running too.

There are limitations to the study’s findings though.

“Because this is a cross-sectional study – which assesses data taken from a subset of the population at a particular point in time – we can’t be sure whether the high-intensity physical activity led to better bone health, or whether those with better bone health do more of this exercise,” Stiles clarified.

“However, it seems likely that just one to two minutes of running a day is good for bone health.”

It’s not the first study to suggest you can drastically improve your health with just a minute’s exercise either: earlier this year, researchers from McMaster University found that 60 seconds of intense exercise broken up into 20 second blasts as part of a ten-minute workout can be as effective as a 45 minute endurance workout.

No more telling yourself you just don’t have the time to keep fit then.

Even modest changes to diet could reduce risk of death, study finds

Image result for Even modest changes to diet could reduce risk of death, study finds

With more than one-third of U.S. adults suffering from obesity, it’s no surprise that many Americans would benefit from healthier eating habits. Fad diets capitalize on our desire for quick results but usually fail in the long run.

Now new research adds to the evidence that a more moderate approach can make a lasting difference.

A study from the Harvard T.H. Chan School of Public Health finds that improving the quality of diet over time, even with modest changes, may significantly reduce the risk of premature death.

Improvements to diet included consuming more whole grainsvegetables, fruits, nuts, and fish and eating less red and processed meats and sugary beverages.

“Overall, our findings underscore the benefits of healthy eating patterns including the Mediterranean diet and the DASH diet. Our study indicates that even modest improvements in diet quality could meaningfully influence mortality risk and conversely, worsening diet quality may increase the risk,” lead author Mercedes Sotos-Prieto, who worked on the study while a postdoctoral fellow in the Harvard Chan School department of nutrition and who is currently an assistant professor of nutrition at Ohio University, said in a statement.

For the study, published in the New England Journal of Medicine, Sotos-Prieto and her team analyzed data on nearly 74,000 adults over a 12-year period. The researchers assessed the participants’ diet using three different scoring methods: the 2010 Alternate Healthy Eating Index, the Alternate Mediterranean Diet score, and the Dietary Approaches to Stop Hypertension (DASH) diet score. Each model assigns scores to various types of food, with healthier foods receiving higher scores and less healthy foods receiving lower scores.

The results showed that better diet quality over a 12-year period was linked to a reduced risk of death in the subsequent 12 years, no matter which method of scoring was used. Whole grains, fruits, vegetables and fish or n-3 fatty acids appeared to contribute most to an improvement in diet quality.

Specifically, the study showed that a 20-percentile increase in diet-quality scores was associated with an 8 to 17 percent reduction in the risk of death.

That can be achieved, for example, by swapping out just one serving of red or processed meat and replacing it with one daily serving of nuts or legumes.

In contrast, worsening diet quality was linked to a 6 to 12 percent increase in the risk of death.

Nancy Z. Farrell, a registered dietitian nutritionist and spokesperson for the Academy of Nutrition and Dietetics, said the findings reinforce the work she does every day with her patients.

“Registered dietitian nutritionists practice evidence-based science every day in encouraging and educating the public on disease prevention and treatment, and we know that chronic disease increases the cost of health care and drives up insurance premiums,” she told CBS News.

Farrell says everyone can benefit from making smart diet swaps as often as possible.

“Have a ‘meatless Monday’ dinner where you incorporate beans or legumes, such as red beans and quinoa. Or have a veggie pizza night,” she suggests.

When it comes to snacking, avoid high-calorie junk foods like potato chips and opt for a handful of nuts, or make your own trail mix with nuts, seeds, and dried fruit.

And if you’re looking for a sweet treat, skip the ice cream and try freezing some fruit instead.

“Blueberries or blackberries offer a refreshing summer snack with a burst of coolness,” Farrell said.

Importantly, experts say it’s crucial to not only incorporate such changes into your diet, but to stick with them over time.

“Our results highlight the long-term health benefits of improving diet quality with an emphasis on overall dietary patterns rather than on individual foods or nutrients,” said Frank Hu, professor and chair of the Harvard Chan School department of nutrition and senior author of the study. “A healthy eating pattern can be adopted according to individuals’ food and cultural preferences and health conditions. There is no one-size-fits-all diet.”

Hair loss in men: THIS shower habit could be why you’re going bald

Image result for Hair loss in men: THIS shower habit could be why you're going baldThe UK has the fifth highest number of bald men in the world.

Indeed, almost 40 per cent of men in this country are losing their hair.

It’s often hereditary – male pattern baldness or androgenic alopecia, which is related to genes and male sex hormones, accounts for 95 per cent of hair loss in men.

Other reasons for thinning hair include stress, anaemia, protein deficiency and low vitamin levels.

However, surprisingly, a recent study published in JAMA Dermatology found there’s no relationship between hair loss and testosterone levels in men.

If you want to maintain your head of hair for as long as possible, start to pay more attention to your daily grooming habits.

Jumping in and out of the shower as quickly as possible might mean more time in bed, but it could be speeding up you going bald.

That’s because taking the time to massage your head as you shampoo stimulates hair growth.

Grooming habits: Not spending long enough in the shower can make a difference

Ananbel Kingsley, trichologist at Philip Kingsley, said: “Scalp massage can be beneficial for those experiencing a gradual reduction in hair volume or hair loss.”

It does this by improving blood flow directly to the area, and by removing dead skin cells which have been proven to cause or worsen hair loss.

She explained: “It should ideally be done for five to ten minutes once to twice a week. It should be gentle yet firm with consistent pressure.

“Using both hands, gently knead your scalp in circular movements starting at the front hairline and gradually working your way back down to the nape of your neck.

“Repeat three to four times, then, with a gentle sweeping action, smooth your hands over the top of your scalp.”

Thinning hair: It could be due to stress and vitamin deficiency

Additionally, a study published in the International Journal of Neuroscience found that massaging your scalp also lowers hair loss-inducing stress levels.

However, Anabel added: “Scalp massage alone will not have a vast impact on hair growth. Its benefits are highly dependent on what is used during massage – try a stimulating scalp mask.

“Additionally, one of the most common causes of hair loss is the result of iron and ferritin – stored iron – deficiency.

“A healthy diet, eating adequate iron and proteins and taking care of your general health will help prevent both hair loss and hair thinning – and will often improve the general appearance of the hair.”

The dangerous diet that could ruin your health

Image result for The Mono Diet says you can eat as much as you want -- but only of one food, such as bananas.

The Mono Diet says you can eat as much as you want — but only of one food, such as bananas.

When Alicia Hunter, 49, heard about a diet where she could eat as much of her favorite fruit as she wanted, the Upper East Side woman was hooked. There was one small catch, though: It was the onlything she could eat.

“In an attempt to lose weight for the holidays, I ate only melon for almost 30 days after I heard about the Mono Diet,” says Hunter, an eyelash-extension professional. “I lost 7 pounds, but I never want [to eat] melon again.”

The diet dictates that you eat only one food for several weeks to lose weight fast, something that many experts warn is dangerous and only successful in the short term. Hunter, however, used it to kick-start a long-term weight-loss plan to shed the pounds, and raved about the benefits.

“I kept the weight off and actually lost another 8 pounds since then on other diets,” she says.

The Mono Diet (sometimes referred to as Banana Island or Monotrophic Diet) has become increasingly popular since a YouTube star nicknamed “Freelee the Banana Girl” (real name: Leanne Ratcliffe) boasted about her weight loss in 2014. She claimed to have lost 40 pounds eating close to 30 bananas a day.

‘It’s an incredibly restrictive and unbalanced diet and I do not recommend that anyone follow it.’

Since then, a new version, the Sweet Potato Diet, was released in April, touting how the spud can help you lose 12 pounds in just two weeks. Meanwhile, the hashtag #monomeal on Instagram, which highlights pictures of people’s meals containing a single food, has more than 38,000 posts, and the diet was one of the most searched in 2016, according to Google. Comedian and magician Penn Jillette even wrote a book last year about how he lost 100 pounds by eating nothing but potatoes for two weeks to kick off his diet. And Matt Damon revealed he ate only chicken breasts to drop weight for his role in “Courage Under Fire.”

“Yes, this diet can produce weight loss,” says Frances Largeman-Roth, registered dietitian and author of “Eating in Color.” “But, the weight loss is a result of caloric restriction — not because any particular food is magically producing weight loss. It’s an incredibly restrictive and unbalanced diet and I do not recommend that anyone follow it.”

In addition to a low caloric intake (Hunter estimates she ate about 800 calories a day worth of melon), which can cause symptoms like dizziness, a Mono Diet can also lead to some serious health problems. The diet landed Ashton Kutcher in the emergency room in 2013 after he followed the “Mucusless Diet Healing System,” and based his diet solely on fruit.

“I ended up in the hospital two days before we started shooting [‘Jobs’],” he told reporters at the Sundance Film Festival. Months later, at a press conference, he said that, “My insulin levels got pretty messed up and my pancreas kind of went . . . crazy. The levels were really off, and it was painful.”

Amy Gorin, a Jersey City-based registered dietitian and nutritionist, says such diets can have “a negative effect on your metabolism and may cause muscle loss. By eating just one food, you’d be taking in too much of certain vitamins or minerals — for example, potassium from bananas. Additionally, it will be very hard to maintain any weight loss once you go back to eating a normal diet.”

While Hunter didn’t have an issue keeping off the initial weight she lost, and raved about her glowing skin, others who tried it didn’t have as great an experience.

“I was desperate to lose weight, so I decided to eat only carrots for an entire month,” says New Jersey music teacher Beth Glickman, 58. “I lost about 10 pounds in one month, but the palms of my hands turned orange! Needless to say, the diet didn’t last much longer than that.”

New blood test could see personalised prostate cancer treatment

A new three-in-one blood test could pave the way to precision-personalised treatment for advanced prostate cancer, say scientists.

The test has the potential to transform the way the disease is tackled by targeting specific gene mutations, it is claimed.

By looking for cancer DNA in blood samples, researchers were able to identify men with defective BRCA genes who were likely to benefit from a class of drugs called Parp inhibitors.

They also used the test to monitor DNA in the blood after treatment started, so patients who were not responding could quickly be switched to an alternative therapy.

Finally, the same test was used to pick up signs of evolving cancer showing the first signs of drug resistance.

Prof Johann de Bono, who led the team at the Institute of Cancer Research in London, said: “We were able to develop a powerful, three-in-one test that could in future be used to help doctors select treatment, check whether it is working and monitor the cancer in the longer term.

“We think it could be used to make clinical decisions about whether a Parp inhibitor is working within as little as four to eight weeks of starting therapy.

“Not only could the test have a major impact on treatment of prostate cancer, but it could also be adapted to open up the possibility of precision medicine to patients with other types of cancer as well.”

In future, the test could allow the Parp inhibitor olaparib to become a standard treatment for advanced prostate cancer, by targeting those most likely to benefit, picking up early signs that the drug might not be working, and monitoring for emerging resistance.

Parp inhibitors such as olaparib block an enzyme used by cancer cells with defective BRCA 1 and 2 genes to repair their DNA.

When Parp is disabled, the cells die. The drugs do not generally work on cancer cells with functioning BRCA genes, because these are primary DNA repair tools that make Parp unnecessary. While some patients respond to the drugs for years, others either fail to respond at an early stage or develop resistant cancer.

The new test, described in the journal Cancer Discovery, was developed with the help of 49 patients enrolled in TOPARP-A, a Phase II clinical trial investigating the effectiveness of olaparib.

Men responding to the drug were found to experience an average drop in circulating cancer DNA of 49.6% after eight weeks of treatment. In contrast, cancer DNA levels rose by 2.1% in patients who did not respond.

Patients whose cancer DNA blood levels were lowered by olaparib survived an average of 17 months compared with 10.1 months for those whose levels remained high.

The scientists also conducted a detailed investigation of the genetic changes in cancer DNA among men who stopped responding to olaparib. They found that the cells acquired genetic changes that cancelled out the DNA repair defects making them susceptible to the drug.

Prof Paul Workman, chief executive of the Institute of Cancer Research, said: “Blood tests for cancer promise to be truly revolutionary. They are cheap and simple to use, but most importantly, because they aren’t invasive, they can be employed or applied to routinely monitor patients to spot early if treatment is failing – offering patients the best chance of surviving their disease.

“This test is particularly exciting because it is multi-purpose, designed for use both before and after treatment, and using both the absolute amounts of cancer DNA in the bloodstream and also a readout of the specific mutations within that genetic material.

“We believe it can usher in a new era of precision medicine for prostate cancer.”

Each year, around 47,000 men in the UK are diagnosed with prostate cancer and more than 11,000 die from the disease.

Dr Matthew Hobbs, deputy director of research at the charity Prostate Cancer UK, which funded the research, said: “It’s clear that we need to move away from the current one-size-fits-all approach to much more targeted treatment methods.

“The results from this study and others like it are crucial as they give an important understanding of the factors that drive certain prostate cancers, or make them vulnerable to specific treatments.”

Windows 10 Build 15019 may be about games, but its many bugs could spoil the fun

Windows 10 game bar beam broadcasting windows 10

The gaming-focused Windows 10 Insider build that Microsoft promised earlier this week, with Game Mode, Beam livestreaming and other features, is rolling out—but with some game-breaking bugs, unfortunately.

What’s officially known as Build 15019 for the Insider Fast Ring also includes a number of more general improvements, including a version of Edge that will read your ebooks aloud and a better out-of-box experience, complete with voice actors to guide you through the process.

If you’re hoping to try out the new PC-centric Game Mode for yourself, though, be wary: Microsoft warned that unspecified “popular games” may experience crashes or black screens when loading, and clicking on certain elements in a Win32 game may cause it to be minimized (and therefore unplayable) unless killed. Even the new Game Mode will show up as OFF when in fact it’s enabled by default. Also, be aware of one download glitch: The issue Microsoft had with its progress bar is still there, so the download will still show “0% completed” even when it’s actually downloading.

“We recognize that this is painful for those wanting to try out the new gaming features announced this week,” Microsoft’s Insider chief, Dona Sarkar, wrote in a blog post. “We deliberated a lot on whether to release this build to Insiders with these issues; however we decided to go ahead and release it as we need feedback from Insiders on other areas of the OS.”

Windows 10’s new Game Mode settings, which are designed to optimize your PC for gaming.

Some great new gaming features

Build 15019 is specifically optimized for gaming, with new additions to both the Xbox One and Windows 10 platforms. (A separate build for Xbox Insiders should roll out today, with support for Screentime, a parental control that is already on Windows 10.) Our previous story outlined the new additions, but we’ll briefly recap them here:

Game Mode: a specific mode for the PC that minimizes the resources other background tasks have at their disposal, giving the game all of the resources your PC can spare. My colleague Brad Chacos has outlined what Game Mode does for your PC. The Windows Game Bar now supports 17 more games in fullscreen mode, including Battlefield 3, Call of Duty Black Ops 2, FIFA 14 and FIFA 17, Rocket League, and more.

Gaming Settings: Microsoft has consolidated gaming controls for Game Bar, GameDVR, and more into a Gaming section in Windows 10’s Settings.

Beam livestreaming: Microsoft bought Beam and its livestreaming technology last year to take the games you’re playing on Windows 10 and the Xbox and broadcast them to others on the Internet. You’ll be able to trigger the Game Bar (Win + G) and show others how fast you can drive in Forza Horizon 3.

Action Center now keeps tabs on your games.

Microsoft also revealed a small additional convenience: If you buy a game from the Microsoft Store app, you’ll be able to track its download progress in the Action Center notifications. The company also fixed a bug that would crash the display controller if an Xbox controller was attached, and another that could cause the screen to flicker if a player used Alt + Tab to change focus to another window.

A better out-of-box experience

Having just reset a balky Surface Pro 4 that couldn’t get past Build 15002, I can confirm that the out-of-box experience that build introduced is excellent—and Build 15019 promises to improve on it even more. Setting up a new PC is now voice-driven: Cortana asks you the questions you’d normally have to be at your keyboard to answer. (For those who are unable to hear Cortana, there are now subtitles.)

Windows 10 out of the box experience

Cortana will guide you through the new “Out of the box” setup experience,

With build 15002 and the latest build 15019, you can be working away at another PC while Cortana’s voice asks you if you’d like to accept the default options and other questions. It’s fun to holler “Yes!” and keep typing.

At one point during build 15002’s reset process, Cortana’s voice was replaced by a more robotic text-to-speech voice. That’s been fixed, with additional voice acting in place to maintain a consistent, pleasant tone. A bit of spit and polish has updated the UI, including the way in which you sign in with a Microsoft account. Windows Hello enrollment, which simply asks you to smile at the camera for a second or two, has also been updated.

Troubleshooters, all in one place

I have sporadic issues at my home office where my Wi-Fi connection needs to be reset, requiring me to right-click my Wi-Fi icon on the Taskbar and launch the troubleshooter. For Build 15019, Microsoft’s grouped all of the Troubleshooter options inside Settings > Update & Security > Troubleshoot so you can see the complete list, including tools for resolving printer issues, Windows updates, Bluetooth, and more.

A bevy of other useful features

Build 15019 adds a number of other useful features, most of which don’t require that much additional explanation:

  • A new “read aloud” button in Microsoft Edge will read ebooks stored in Edge in 24 languages.
  • Windows 10 Microsoft edge aloud

    Edge’s new “read aloud” interface.

  • Full-color emoji, on those sites that use them.
  • Blue light support, which removes the blue colors your display produces late at night so as to help prevent insomnia. (Microsoft now calls the feature “night light.”)
  • If you use the Hyper-V feature to create virtual machines, you can now resize the window and the guest OS will rescale the resolution appropriately.

Could,this,be,the,Samsung,Galaxy,S8’s,official,press,render?

Thursday and Friday brought a lot of news from the Galaxy S8 rumor stack including a leaked live-image and a full list of alleged specs, including a strange resolution that ends up being higher than the LG G6’s. But anyway, the following is an image of what is believed to be an official render of the Samsung Galaxy S8.

Now, if you compare the render to the live image we saw on Thursday, they coincide pretty well. The proportions of the camera module next to the rear-mounted fingerprint sensor look spot-on in the image.

If we look at the front of the render, and then look back at the supposed front-glass panel for the Galaxy S8, the two aren’t consistent with the leaks we are getting. So either this is fake, or that glass is.

More will reveal itself in the coming weeks. We are still looking at a March 29 Unpacked event, as well as an April 21 official sale date. Check out the full list of recently-leaked specs here.

After IIM bill, more central institutions could be granted autonomy: Javadekar

Giving autonomy to IIMs is a “milestone” Javadekar said adding that while government will continue to provide funds for the development of these institutes but “sans government controls”

  • Quality of education remain a challenge, but access to higher education improved: Venkaiah Naidu
  • Instead of taking over private schools, improve public schools: Delhi High Court
  • 10 districts awarded on National Girl Child Day for contributing towards woman empowerment
  • DU: First public university to hoist

On the lines of the IIM Bill, more Central institutions could be given autonomy and freed from government’s “micro-management”, said Union HRD minister Prakash Javadekar.

He also expressed hope that the proposed legislation would come in the upcoming Budget Session of Parliament and would be passed soon.

A day after the cabinet gave its nod to IIM Bill, 2017 which empowers these institutes to give degrees, Javadekar in an interaction with reporters said that it gives autonomy also in establishing a system of accountability in terms of CAG audits and presenting reports to the Parliament.

Giving autonomy to IIMs is a “milestone” Javadekar said adding that while government will continue to provide funds for development of these institutes but “sans government controls”.

Views of HRD minister Prakash Javadekar:

“It is not necessary that an IIM Director should sit at the table of a ministry Joint Secretary,” Javadekar said. Javadekar had mentioned that he may not be the chairperson for IIM Bill, but someone from among Directors could be.

The IIM Bill has a provision for setting up a coordination forum, the chairperson of which would be an eminent person, chosen by the members, it is learnt.

The HRD minister said that the IIM Bill was an indication that other institutes, which excel in their field, could get more autonomy. He said it was being considered that best institutions are given maximum autonomy, those which are average get some autonomy and some regulation while a different system is there for those which are not performing too well.

Asked if the ministry planned to take the IIM Bill to the Parliament in the upcoming Budget session, Javadekar said that the government would introduce the Bill. “If the House decides they can straight away discuss, or if comes to a Standing Committee, I am still sure it will be passed soon,” he said.

He said that the mentality that government would taking care of the money, control and everything else would not work in education. “India lacks in innovation, and it comes with young minds working free and where there is no fear of failure,” the HRD minister said.

As he emphasised on the importance of giving more autonomy, Javadekar said that Modi government is a very democratic one where decisions are taken on the basis of consultations. “In this government, no letter comes from somewhere,” he said in what appeared a dig at political rivals.

Speaking about the IIM Bill, Javadekar said that there will be periodic reviews of the functioning of these institutes. Responding to question whether the IIMs would be able to set up campuses abroad, Javadekar said that would be subject to the existing norms.

On a question about reservations, he said the law of the land would apply. He also refuted questions that there were differences between the HRD ministry and PMO on the provisions of the Bill.

Asked about when the HRD ministry would announce a new panel to work on the New Education Policy, Javadekar told the reporters that they may have to wait a bit in this regard

This gene could help fight obesity

Scientists have identified a gene that could protect against obesity by increasing the feeling of fullness, a finding that may lead to potential new therapies to treat eating-related disorders.
Researchers from King’s College London and Imperial College London in the UK tested a high-fat diet, containing a fermentable carbohydrate, and a control diet on mice. They looked at the effect on food intake of those with and without the FFAR2 receptor, a protein coding gene.

The results showed that mice fed the diet containing fermentable carbohydrate were protected against obesity. However, this protection was lost when the FFAR2 receptor was not present.

Indeed, those with the receptor showed an increase of 130% in the satiety inducing gut hormone peptide YY, as well as an increased density of cells containing PYY, leading to an increased feeling of fullness.

“Obesity is currently one of the most serious global threats to human health, determined by genetic background, diet and lifestyle,” said lead author Gavin Bewick from King’s College.

“We know that supplementing your diet with non-digestible carbohydrates reduce appetite and body weight gain, but in this study we demonstrate for the first time the essential role of the FFAR2 receptor in enabling specific dietary constituents to reduce food intake and protect against obesity,” said Bewick.

“With this discovery, we can start to look at whether we can use diet or pharmaceutical means to change the cellular make-up of the gut in order to treat a host of disorders,” he said.

“This a major step forward in understanding the relationship between diet and appetite regulation. Until a few years ago dietary fibre was a thought of as inert, and having very little effect on physiology,” said Gary Frost from Imperial College.

So the fact it actually has a major impact on cells that help control appetite regulation in the colon is amazing,” Frost said.

“Our challenge now is to translate this into a technology that we can apply to humans. We need to understand how we can use the knowledge and insight gained to develop food systems that are attractive to a large percentage of the population,” he added. The study appears in the journal Nature Reviews Endocrinology.

Marijuana could help treat drug addiction, depression

Nov 17, 2016, 02.05 PM IST

Marijuana could help treat drug addiction, depressionMarijuana could help treat drug addiction, depression
Using marijuana could help some alcoholics and people addicted to opioids kick the habit and may also help people suffering from depression, post-traumatic stress disorder (PTSD) and social anxiety, says a study.

“Research suggests that people may be using cannabis as an exit drug to reduce the use of substances that are potentially more harmful, such as opioid pain medication,” said the study’s lead investigator Zach Walsh, Associate Professor at University of British Columbia’s Okanagan campus in Canada.

The study published in the journal Clinical Psychology Review is based on a systematic review of research on the medical cannabis use and mental health as well as reviews on non-medical cannabis use.

However, the review concluded that cannabis use might not be recommended for conditions such as bipolar disorder and psychosis.

“In reviewing the limited evidence on medical cannabis, it appears that patients and others who have advocated for cannabis as a tool for harm reduction and mental health have some valid points,” Walsh said.

It is important to identify ways to help mental health professional move beyond stigma to better understand the risk and benefits of cannabis, Walsh added.

“There is not currently a lot of clear guidance on how mental health professionals can best work with people who are using cannabis for medical purposes,” Walsh said.
