Porter

Diet books, they鈥檙e everywhere, particularly at this time of year, but not here on Inside Health. 听Why? 听Margaret McCartney explains.

听

And stomas 鈥� what鈥檚 it like living with a bag?听 There are over a 100,000 people in the UK who鈥檝e got one.

听

Adams

It was my large colon which was completely removed.

听

Porter

Are you happy to show me your stoma?

听

Adams

Yeah, of course, absolutely.

听

Porter

So, how tall are you roughly?

听

Adams

I鈥檓 six foot two.

听

Porter

You鈥檙e a slim chap and outwardly there鈥檚 no sign that you鈥檙e any different from me.听 I can see it, just underneath your t-shirt, now you鈥檙e taken your top off.

听

Adams

You saying that is a confidence boost.

听

Porter

More from Michael later.听 But first, a subject that is particularly dear to our hearts at Inside Health 鈥� conflict of interest. 听And, while we were off air, there were a couple of developments in the public health arena that got us twitching. 听Both to do with drinks 鈥� hard and soft.

听

Margaret McCartney is in our Glasgow studio.

听

McCartney

So, there鈥檚 been two interesting stories that were announced towards the end of 2018 that I think made many people sit up and take a bit of notice.听 One was the partnership that was announced between Diabetes UK and Britvic, the soft drinks manufacturer, and the other was between Public Health England and an educational charity called Drinkaware.

听

Porter

Well, first of all, let鈥檚 look at the Diabetes UK.听 So, this is a patient group, a charity, taking money from a soft drinks manufacturer.

听

McCartney

So, Diabetes UK is a very well-known big charity that has interests for people with both Type 1 and Type 2 diabetes.听 And in November they announced that they鈥檇 accepted a partnership worth half a million pounds from Britvic.听 And Diabetes UK say on their website that this money was designed to support those living with and at risk of diabetes: 鈥淥ur aim is to help Britvic employees to reduce their risk of Type 2 diabetes and support children with Type 1 diabetes and their families, so they thrive at school鈥�.

听

Porter

But I suppose the problem is that Britvic will be selling some of the products that people are pointing to as part of the reason behind an epidemic in Type 2 diabetes.

听

McCartney

Yes, so I think many people have noticed there鈥檚 a bit of an irony, at least apparently so, that means that perhaps this might not have been the partnership that makes the most logical sense to people, particularly who are at risk of Type 2 diabetes.

听

Porter

And what have Public Health England been up to?

听

McCartney

Public Health England have had an interesting alliance.听 They went into partnership with an organisation called Drinkaware.听 Now they have said that: 鈥淭his is a fresh and bold step in our work to reduce alcohol harm鈥�.听 But the concern is that Drinkaware is an organisation that is funded by the alcohol industry.听 And of course, it鈥檚 so difficult to prove conflicts of interest in this area and the impact that they have but the concern has been such that people, well-known people, for example, like Sir Ian Gilmore have actually resigned from their position at Public Health England in protest at this partnership.

听

Porter

Well that partnership was the Drink Free Days campaign designed to encourage middle aged drinkers to have more days off alcohol.听 And Professor Sir Ian Gilmore hasn鈥檛 spoken to the media about his decision to step down. 听Until now.

听

Gilmore

Public Health England is under huge pressures on many fronts trying to deal with dwindling resources and I fully understand how they鈥檙e looking for partnerships but I think to involve alcohol producers in developing public health policy, public health messaging to the public, is wrong.听 And that then leaves us in a difficult position with Drinkaware because they do have an independence.听 Nonetheless, they do get the vast majority of their funding from alcohol producers.

听

Porter

The implication there is that the alcohol producers might use a third-party organisation, like Drinkaware, to subtly shift or nudge public health policy in the favour of their shareholders, in other words selling more alcohol.听 Is that the basic concern?

听

Gilmore

That is the concern and I鈥檓 not saying, with any certainty, that it happens in the case of Drinkaware but producers really have a single obligation to their shareholders and I think it鈥檚 wrong to expect them to be involved in public health messaging, for example.听 I鈥檓 not against working with the drinks industry and the producers included in that, provided it鈥檚 something that they can do, like the strength of alcohol products, like labelling.听 If you look at the history of the tobacco industry, for example, it鈥檚 full of examples where they use third parties, offshore groups, etc., to lobby on their behalf or to promote policies and so on.

听

Bauld

I think we have the most substantial evidence in this area from tobacco because we have decades of looking at how the producers of tobacco products have tried to influence evidence and public perceptions through these kinds of partnerships.

听

Porter

Linda Bauld holds a chair in behavioural research at Cancer Research UK and is Professor of Public Health at the University of Edinburgh.

听

Bauld

What tobacco companies have done historically is try and influence the evidence base by building their reputation through, for example, funding think tanks, contributing to groups that are willing to talk about the evidence in a way that meets the objectives of the tobacco company.听 So, there are some very good examples, through history, I mean classic ones like funding the Centre for Indoor Air Research, which pushed back against smoke free legislation, promoting research on the benefits of low tar cigarettes, saying they鈥檙e safer when we now know from many studies that they鈥檙e not.听 Arguing that tobacco marketing doesn鈥檛 have an influence on people鈥檚 choices to smoke and delaying for many decades, actually, attempts to limit marketing.听 So, that鈥檚 the evidence from tobacco.听 And what they鈥檝e done is try to build partnerships with other organisations which will speak with their voice, rather than them having to do it themselves.听 So, we鈥檙e very familiar with those tactics, in fact they鈥檝e been researched by social scientists and others.听 And we now know, more recently, that similar tactics are being used by other commercial companies that sell products which may be harmful.

听

Porter

Well it would be na茂ve, wouldn鈥檛 it, for those companies not to look at tobacco as an example, I mean if you鈥檙e wanting to sell alcohol or these days sugary drinks, for instance.

听

Bauld

Absolutely, I mean what we鈥檝e seen in both the soft drinks industry and in the alcohol industry is similar to what happened with tobacco is that the big multinationals tend to merge, so they become huge companies, they have big, big budgets to put into research and marketing.听 They do employ similar tactics.听 And at the end of the day, it鈥檚 not rocket science, because they鈥檙e trying to sell a product they are going to want people to consume it and they鈥檙e going to want people to believe things that fit with that kind of consumption and that鈥檚 why they try and behave in this way.

听

Porter

We live in a more cynical era now, though, than perhaps in the heyday of the tobacco industry doing this, is there the same sort of evidence that the soft drinks industry, for instance, or alcohol industry are altering policy in their favour?

听

Bauld

Absolutely, in fact just this month we鈥檝e seen a very thorough study investigation done of Coca Cola鈥檚 activities in China and how they, over several decades, funded the International Life Sciences Institute, which essentially produced a lot of research which promoted physical activity as a solution to obesity.听 And of course, physical activity is really important but the best thing we can do to reduce obesity rates is change what people consume, including sugary drinks.听 And we know, also very recently, that the alcohol producers had funded a large trial in the US, funded in partnership, unfortunately, with the US government鈥檚 National Institutes for Health, and there was an investigation of that and the documents showed that that trial was basically set up to promote continued moderate drinking.听 So, unfortunately, we鈥檙e continuing to see research findings uncovering this kind of influence, similar tactics, to the tobacco industry.听 We might be wiser nowadays but what we call the commercial determinants of health, the power and might of these industries, is very difficult to tackle.

听

Porter

But industry will come back and say look well we are funding education and awareness campaigns and increasingly these days warts and all ones that tell the whole story.

听

Bauld

You know, a tactic of commercial actors is to engage in corporate social responsibility, where they do invest in education campaigns, often which appear to be not promoting their product.听 Giving people information, i.e. through a public information campaign, is of course helpful to support people to make choices but actually in terms of reducing things like problematic drinking, preventing smoking uptake or promoting smoking cessation, education itself actually makes very little difference.

听

Gilmore

There鈥檚 very little evidence that public education and information is a very powerful tool.听 I鈥檓 not saying we shouldn鈥檛 do it but we should not fund this at the expense of the things that really drive harm.听 Public Health England produced a very powerful evidence review a couple of years ago where they highlighted what were the key drivers of how much a population drinks and how much harm it gets and those were quite simply price, availability and marketing.听 And what I don鈥檛 want to see is the kind of smokescreen around public information at the expense of those things that really work.

听

Porter

So, in a tie up with a relationship like this it could be that they manage to nudge, somehow, somebody like PHE off the things they should be doing and on to strategies that might still be helpful but not as helpful?

听

Gilmore

I鈥檓 certainly not saying that they have done that but a relationship is a relationship, engagement is engagement and that鈥檚 the very reason why one is always cautious.

听

Bauld

There are glimmers of hope, some attitudes are changing.听 We have seen some corporate companies like Mars pulling out of funding some of these big organisations.听 We have a new foundation set up by Philip Morris, Foundation for a Smoke Free World, that has been heavily criticised.听 So, we鈥檙e seeing movement on both sides.听 But this current example from England is not a good one and I think it needs to be very seriously reconsidered.

听

Porter

But it鈥檚 not the only one that we鈥檝e had recently either, I mean Diabetes UK tying up with Britvic, they鈥檝e done a lot to justify that but in your mind are you still worried about those sorts of tie ups, which are going on, you know, in lots of different organisations because money talks?

听

Bauld

Yeah, I don鈥檛 think they鈥檙e going to improve public health, no matter what people believe.听 I am sympathetic to why it happens and the main reason for that is there is so little money in the system for public health.听 Just this month we鈥檝e seen a promising NHS plan published that says it wants to focus on prevention and at the same time public health budgets, often in local government, are still being brutally slashed.听 So, of course, these organisations are going to look for money from elsewhere.听 But, and my own view, is that this partnership was a mistake, even though Drinkaware is an independent charity, it is entirely funded by the producers of alcohol and the companies who sell alcohol and I just still think there is a conflict of interest.听 And the problem is if those types of partnerships are allowed to continue then the public is less likely to trust what PHE might say on other topics, where it is doing very good work.

听

Gilmore

Public Health England may not realise this but I am concerned about their reputation.听 They are, if you like, government鈥檚 arm of public health and no doubt that they were potentially, in my view, going to suffer from reputational damage.听 One of the problems is that funding from Drinkaware is still seen by public health researchers as being in some way tainted and I fully accept that there鈥檚 a lot of independence, they have a medical advisory board, there are some good people involved but there is still that, I think, genuine concern and one that鈥檚 quite hard to dismiss when Drinkaware has not, in my view, taken all the opportunities it could to make itself whiter than white.

听

Porter

Sir Ian Gilmore and Linda Bauld. We contacted Drinkaware who stressed in a statement that:

听

鈥淭he Drinkaware Trust is an independent charity which is not part of 鈥� and does not speak on behalf of 鈥� the alcohol industry.鈥�

听

Well, the Director of Health Improvement at Public Health England is Professor John Newton. 听Are you concerned that your organisation鈥檚 image has been tarnished?

听

Newton

Well Sir Ian and Linda Bauld are very respected colleagues, so obviously we鈥檙e concerned that they feel there is a danger of that.听 We obviously had to take a judgement.听 We certainly do not have direct partnerships with the alcohol industry and certainly not the tobacco industry and we鈥檙e very aware of the lessons from the past, which your interviews have drawn out very well.听 Drinkaware, as Sir Ian says, is a charity and we work with charities all the time and charities receive funds from lots of different donors and it鈥檚 not, to some extent, not our job to investigate the charities.听 But Drinkaware is a special case and we understand that.

听

Porter

I suppose the criticism is that history tells us that such tie ups, I mean I know it鈥檚 through a third party, a charity, in this case which is supposedly completely independent, there are some vested interests there and experience shows that that has an impact on policy in the end.

听

Newton

There certainly are and we have to make a judgement.听 So, we have learnt lessons from the reaction, we鈥檝e looked into it.听 The reaction was actually quite mixed, there was a very supportive leader in The Times recognising that if we are going to change public consumption and we are going to address these new drivers of public health, we have to work, in some way, with the industry, as indeed Sir Ian said.听 Drinkaware is out there putting messages out to the public and this partnership is a limited partnership, so that we can make sure those messages are evidence based.听 We鈥檙e very conscious, we do not allow that partnership to influence our policy.听 So, we have, as a result, we have worked with Sir Ian and Linda to develop some guidelines which we hope will make our thinking on this, make it clearer in the future and make it very clear where the boundaries like.听 There have to be boundaries.听 Ultimately, it鈥檚 a question of how much change you can expect to get if you don鈥檛 do anything.

听

Porter

One of the concerns is that the boundaries might be a little bit blurred.

听

Newton

Well boundaries are blurred but we have to act.听 It鈥檚 all about us influencing them and not about them influencing us.

听

Porter

You hope.

听

Newton

I feel confident about that.

听

Porter

Professor John Newton. 听And, as ever, there are more details on the Inside Health page of the Radio 4 website.

听

Now to something you don鈥檛 hear discussed that often 鈥� stomas. 听It may not be obvious when you meet them, but around one in 500 people in the UK 鈥� children and adults 鈥� live with some form of bowel stoma, where part of their gut has been brought out through their abdominal wall to empty into a bag. 听But how does it all work, and what it鈥檚 like living with one?

听

I went to Addenbrooke鈥檚 Hospital in Cambridge to meet Michael Adams, who had a colostomy after his colon was removed because of severe inflammatory bowel disease.

听

Adams

I was diagnosed with ulcerative colitis.听 I had fatigue, constantly needing to go to the toilet, anything up to 30 times a day, not being able to make it to the toilet in time, loss of blood鈥�

听

Porter

Pretty poorly?

听

Adams

Very poorly.

听

Porter

So, you were offered medication, presumably, but was the medication not working?

听

Adams

No.听 The only stuff that really helped was the steroids and I was on a large amount of steroids which cause a lot of damage to the body and affected me quite a lot.

听

Porter

When was the prospect of surgery first raised and how was it raised?

听

Adams

When I was talking to my consultant about more medication I kind of had a little bit of a breakdown in his office and I just said 鈥� just get this out of me.听 I鈥檇 just had a young child and I wanted to enjoy him and my wife and that as well and I just 鈥� just get it out of me.

听

Power

My name is Michael Power, and I am a Consultant Colorectal Surgeon at Addenbrooke鈥檚 Hospital in Cambridge.

听

Michael had ulcerative colitis, which is a form of inflammation of his large intestine.听 When you look at it from the inside it would essentially look red raw, areas which would be bleeding, there would be ulcers鈥�

听

Porter

Nasty.

听

Power

Nasty.听 And so a stoma is when we bring part of the bowel to the surface of the tummy wall so that the bowel contents can go into a bag on the surface of the tummy.听 There are a variety of reasons why we would do that and some stomas that we create are temporary and some are permanent.听 Essentially, the bowel is made to be inside of your tummy, not brought to the surface, so what we鈥檙e essentially doing is making an opening in the skin and then the bowel is essentially stitched to the skin of the surface.

听

Porter

To put it crudely, is it a bit like poking a hosepipe from the inside through the bowel wall and then stitching the edge of that hosepipe to the skin?

听

Power

It is, there are nuances to doing that and when鈥�

听

Porter

Thought there might be.

听

Power

鈥�when you鈥檙e bringing out the small intestine, which is called an ileostomy, the small intestine contents can be irritant to the skin.听 And so often, to use your analogy of the hosepipe, you want the hosepipe to sit slightly prouder of the skin so the bowel contents go straight into the stoma bag on the surface rather than irritate the surrounding skin.

听

Porter

And that鈥檚 because there are all sorts of digestive enzymes etc. in that that are designed to help us digest the meal and can actually inflame the skin?

听

Power

That鈥檚 correct, yes.

听

Adams

So, it was my large colon, which was completely removed.听 I was in hospital for a week.听 Overall, I was off work for a month.听 But I was kind of being restrained after two weeks because I needed to get up and move.

听

Porter

Do you mind 鈥� are you happy to show me your stoma?

听

Adams

Yeah, of course, absolutely.

听

Porter

So, how tall are you, roughly?

听

Adams

I鈥檓 six foot two.

听

Porter

You鈥檙e a slim chap.听 And outwardly there鈥檚 no sign that you鈥檙e any different from me.听 I can see it just underneath your t-shirt, how you鈥檝e taken your top off.

听

Adams

You saying that is a confidence boost鈥�

听

Porter

Right.

听

Adams

鈥�for me as well because I work in London and I鈥檓 normally in shirts and a suit and stuff and when I first had the operation, I didn鈥檛 want to see anyone, I didn鈥檛 even want to see my wife, I didn鈥檛 want her to see me as I was because I felt like it wasn鈥檛 me.听 But then over time, one of my work colleagues, he actually met me, walked me into the office, said 鈥� right, Ian, come on, let鈥檚 go.听 The first thing he said when we got in the office, he said, let me have a look.听 And it was kind of a bit like 鈥� ah, what was I worrying about?听 Gets rid of that stigma of having a bag.听 It doesn鈥檛 mean anything different, it鈥檚 just something on your belly, you just get on with it.

听

Porter

So, it鈥檚 about the size of a crisp packet, I can鈥檛 see the fixings underneath.听 So, just describe where it is because I mean our listeners obviously can鈥檛 see but perhaps you could explain.

听

Adams

So, it鈥檚 just above my waistband on the right-hand side.

听

Brewer

My name is Anna Brewer and I鈥檓 a clinical nurse specialist in stoma care.

听

I have a typical colostomy bag, so you鈥檒l see it鈥檚 a bag that doesn鈥檛 open at the bottom and then an ileostomy bag, similar bag, but it does open at the bottom.

听

Porter

Flesh coloured from the back, so I can鈥檛 see the content.

听

Brewer

No but most of them do have a split cover, so you can peep through, which lots of patients find reassuring for placing the bag.

听

Porter

Can you turn it over and what鈥檚 on 鈥� so this is the patient side, this is the bit that sticks to the skin.听 Basically, it鈥檚 an adhesive patch and there鈥檚 a hole in the middle of it and you adjust the size of the hole depending on the size of your stoma.听 Are they scared about the prospect of having a bag?

听

Brewer

Very scared.听 A lot of concerns about living with a bag, body image is obviously a massive factor.听 A lot of people are keen to proceed with surgery because they鈥檝e been living with incontinence or being going to the toilet very frequently because they鈥檝e been so unwell.听 So, actually it comes as quite a blessing.听 There are a certain amount of people that never love their stoma and very often they are there as a temporary thing while they鈥檙e recovering from surgery.听 I would say they find it harder to deal with, in a way, because they know at the end of the day, they鈥檙e going to get rid of it.

听

Power

Usually the first question is the permanency of the stoma.听 Sometimes stomas are temporary and sometimes they鈥檙e permanent and an example of a temporary stoma would be when we鈥檙e planning to operate on someone who has a bowel cancer in their rectum, which is the last bit of the large intestine, just above the back passage.听 In a proportion of patients where we remove that cancer, we make a join in the bowel, which is called an anastomosis, but to give that join a chance to heal and knit together we will divert the flow of the bowel contents.听 I normally explain to patients, just like you have a crash on the motorway you have a slip road diverting the traffic, that鈥檚 the rationale for bringing the bowel out as stoma upstream from the join and then at a later interval we can close the stoma.听 There are cases where we have to do a permanent stoma.听 So, for cancer patients that can sometimes be where the cancer is so low down in the rectum that it鈥檚 close to the muscles that control our bowel function.

听

Porter

What sort of things can go wrong from a surgical point of view, what do you warn your patients about?

听

Power

If you form a stoma of the small intestine that can have a fluid output and sometimes patients can produce a lot of fluid.听 That fluid would normally, when you鈥檙e in circuit, be reabsorbed into your system but if the rest of your bowel is not in circuit then losing that amount of fluid can cause you to become dehydrated, upset your normal balances of salts that we have in our body.听 Replacing that fluid is very important because becoming dehydrated can affect your kidney function and various other things.听 More potential problems with the stoma later are issues with developing a hernia around the stoma, especially if there鈥檚 rapid weight gain.听 By definition we鈥檙e making a hole in the tummy wall to bring the bowel to the surface, hence there is a weakness at that site.

听

Adams

So, the only issue is the hernia.听 Obviously, there鈥檚 an opening鈥�

听

Porter

Slightly bigger than it should be.

听

Adams

Yeah, whereas before when I had colitis eating habits and stuff were just dreadful.听 Coming back to having this new lease of life I eat everything.

听

Porter

How often do you have to empty the bag?

听

Adams

Three to four times a day?

听

Porter

And do the contents of the bowel continually leak out?

听

Adams

I鈥檓 now at a stage where I kind of understand when things are going to happen, so I kind of plan my bag changes around that.

听

Porter

Might you get an extra activity after you鈥檝e eaten for instance?

听

Adams

Yeah, so, I know that if I have breakfast in the morning, I know that when I have lunch that鈥檚 going to push breakfast through.

听

Porter

Right, okay.听 What about air 鈥� gas 鈥� do you end up with an inflated balloon every so often?

听

Adams

Sometimes, sometimes.听 There鈥檚 a filter on the bag which allows it to release, without a smell.听 I鈥檝e had some interesting moments in large meetings鈥�

听

Porter

Yes, because you can鈥檛 clench your buttocks and stop that can you, no, so it鈥檚 just going to happen.

听

Adams

No, no, it did happen once and I kind of quickly鈥�

听

Porter

Blamed it on the person next to you.

听

Adams

Yeah, give them a nudge.

听

Porter

How reliable has the bag been for you?

听

Adams

For me reliability 鈥� I鈥檓 so active, I can do everything.

听

Porter

When you say you鈥檙e active, what sort of things do you do?

听

Adams

Cycling, swimming, running.听听 I played rugby the other day.听 My son thinks I鈥檓 a superhero because I鈥檝e got a bag on my belly, he thinks it gives me massive powers, so he calls me his superhero daddy.

听

Porter

Yeah, that鈥檚 something you鈥檝e encouraged no doubt.

听

Adams

Oh, absolutely, absolutely.

听

Porter

But people do have a perception, often a misperception, of what it鈥檚 like to have in inverted commas 鈥渁 bag鈥�.听 Do you ever come across that, they say, oh you poor thing?

听

Adams

Yeah, a couple of times on holiday.

听

Porter

So, you鈥檙e in your shorts?

听

Adams

Yeah, yeah, shorts and I鈥檓 happy to walk around, top off, on holiday and why shouldn鈥檛 I?

听

Porter

Michael Adams with the team looking after him at Addenbrooke鈥檚 Hospital in Cambridge. And there is more information on stomas on our website.

听

Shops, websites, TV, radio, magazines, newspapers, they are all full of the latest diet books promising to succeed where their predecessors have failed. 听It is a huge industry appealing to a massive audience keen to shift excess weight. 听So, why don鈥檛 they feature more here on Inside Health? 听Margaret McCartney.

听

McCartney

Let me get my conflicts of interest out of the way.听 I love working on Inside Health and one of the reasons is because it is a place to take a sideways step out of the media spin cycle and pick apart the evidence, question what we know and ask whether what sounds like a good idea in theory is actually a good idea in practice.

听

The health media cycle is otherwise relentless.听 New diet, new you.听 Every week a new slew of diet books lands in the mailbags of editors and producers.听 Diets to make you thinner, wholesome, more muscular, happy, energetic, slimming diets to give you wellbeing or a detox or a cleanse, to give you better skin, a longer life or vitality.听 This fat load of new diet plans lands heavily in bookshops with a promise of a new magic formula to do whatever it was that all last year鈥檚 diet books didn鈥檛.

听

We rarely talk about new diets on Inside Health.听 The last time was to rummage over the evidence for the five/two diet, which had been heavily promoted on the 麻豆社.听 There are many reasons why I do not like diet books.听 It is certainly true that as a nation we tend to be overweight and it also true that many diet books are immensely popular and that many people like them.听 But in the main, books promoting a particular diet are usually a mixture of bad science, hype and short-term solutions.

听

Let鈥檚 face it, despite the massive diet wars of low fat versus low carbo or paleo versus vegan or grapefruit versus cabbage, there is actually rather a lot of scientific agreement about what a healthy diet is and isn鈥檛.听 Namely that fruit, vegetables, olive oil, fibre, variety and wholegrains are generally good and concentrated high sugar foods are generally bad.听 That sensible advice however, does not fill a book, create a brand, make a guru, net a primetime television series or create a massive queue at a private diet clinic.

听

Instead, most media friendly new diets rest on a platform of overstated evidence and understated uncertainty.听 Diet books usually promise a single best solution to lose weight when in fact there may be a variety of sensible options which rest on the same premise.听 To lose weight there needs to be a calorie deficit, which one is capable of continuing over weeks and months and years and which still supplies all the nutrients the human body needs.听 True a book may have helped you do that but it doesn鈥檛 mean that same advice will help every other human.听 Diet books are a symptom of a culture that we should not pander to, full of fat shaming and accusations of moral failure.听 It is an industry whose very presence we should challenge because its existence proves its failure.听 A system problem, rising population weight, needs a system solution 鈥� real public health interventions, rather than blaming individuals.听 That means thinking carefully about what might help to prevent and treat obesity on a population basis.听

听

Food should be a source of pleasure.听 We need nourishments and what we eat is a combination of what we can afford, plan, have and like.听 We鈥檙e individuals with individual preferences and circumstances and promising a single diet solution as the only route to perfection isn鈥檛 fair or helpful.听 And that鈥檚 why we rarely talk about diet books on Inside Health.
