Column: What are the real dangers in our eating habits?

There’s a key problem with most of our diets – and we probably don’t even realise it, writes Sarah Keogh.

Sarah Keogh

THE PHRASE ‘YOU are what you eat’ has been used so much that we often overlook just how true it is.

We really are made out of what we eat – the food we take in becomes our skin, muscles, bones and brains – and so what we eat is an essential part of our health both now and into the future. Food is also one of the places where people can really take control of their health. We can choose to eat high fibre cereals and brown bread, to get our five-a-day from fruit and vegetables and decide whether or not to take supplements. But what are the real areas of our diets that we need to look at for health and where should we go to get good, reliable information about nutrition?

Basic healthy eating hasn’t changed in many years – we still need lots of fibre, we still need plenty of fruit and vegetables and too much fat is still bad for us. But there have been some changes in focus and one of the most important areas we need to look at is fibre. Currently in Ireland, almost 80 per cent of adults don’t eat enough fibre – but unfortunately most people think they are eating enough fibre so they regularly overlook this key part of their diet.

Detox

Why is fibre so important? At its most basic fibre helps to keep our digestive systems working well, which helps us to naturally detox and avoid some common bowel problems. Fibre reduces the risk of heart disease and dramatically reduces the risk of several types of cancer. It also helps us to stay at a healthy weight – and in light of our current obesity problem this is a key benefit. People who eat lots of fibre find it much easier to lose weight or to stay at a healthy weight as fibre helps to reduce snacking and lowers the GI of the diet. Also, if you eat lots of fibre you will lose about 150 calories per day as the fibre (which is undigested) leaves your body.

The reason so many people don’t eat enough fibre is that they think there is a lot more fibre in foods than is actually the case. We need to eat 24-35g of fibre per day – but most people rarely eat more than 14g. Fibre is found in high fibre cereals but a bowl of high fibre cereal rarely contains more than 6g of fibre and many cereals have no fibre at all. We really need to read the nutrition labels of foods to check the fibre content. A piece of fruit only has about 2g of fibre – and this is why we talk about eating lots of fruit and vegetables. Lots of people think that by having cereal for breakfast and a piece of fruit at lunch they are getting all of the fibre they need but they are probably only getting 8g!

One of the best places to pick up fibre is beans and lentils. A half can of beans will have about 12g of fibre and seeds are another good place to pick some extra fibre. The rule for fibre is to think about it at every meal. If you only eat fibre at breakfast, chances are you won’t be getting enough.

Danger

The other big danger to our diets is all the conflicting information that is out there about diet. Every website, newspaper and radio show has some sort of nutritional expert talking about nutrition but giving different (often incorrect) advice. We hear that we shouldn’t eat dairy foods, should cut out wheat, should actually eat saturated fat and lots of other messages that go against the healthy eating guidelines.

Why is there so much confusion? The real problem is that in Ireland there is nothing to stop anyone from calling themselves a nutritional expert (eg nutritionist or nutritional therapist) even if they have little or no recognised qualifications. We don’t tolerate this when it comes to doctors and pharmacists dispensing medication, but when it comes to nutrition, we have no way of knowing if the advice we are getting is accurate or even safe. This means that there are plenty of unqualified people giving advice that is incorrect or even dangerous.

Luckily this is about to change. The Irish government is brining in statutory registration for dietitians in Ireland. From 2012, CORU, the government body that oversees the registration of health professionals in Ireland, will be extending their remit to statutory registration for dietitians. This means that only dietitians or nutritionists with recognised qualifications in nutrition will be able to call themselves dietitians. This means that they will have university level degrees in nutrition as well as training overseen in recognized teaching hospitals.

In the future, anyone looking for advice on diet will be able to tell straight away if the person they are speaking to is properly qualified and giving safe advice by checking if they have state registration.

    • Apologies Colm it’s the Oireachtas committee for Health she’s vice chairman of. Being from Waterford we got to hear so much about her having the ‘ear’ of James Reilly and thus better in than out of the Labour party I mistakenly promoted her. Still….. health?

    • We are eating GMO and lots of us don’t even know this.to avoid GMO eat organic

    • Hey Eddie,
      If you are in the EU you can relax for now. GM is not approved for human consumption and so we do not have GMOs in our food (yet).
      Some of the pellet fed animals are getting GM feed, if this worries you it may be best to stick to organic, grass fed meat (and check out the farm to ensure they aren’t using round up on the grass!)

      While I’m at it, there’s no need to worry about rBGH (recombinant Bovine Growth Hormone) in our beef or dairy either as the EU banned it. We pay a fine to the WTO for doing so, because this puts a ban on beef and other bovine products from countries which use it. This is unlikely to change as in the EU it is banned on health grounds.

      The GM thing may or may not change, but at present, you don’t get GM foods on sale in the EU. By comparison, in the states – a retailer which claims to be organic, “Whole Foods” have been exposed for using GM soy and corn. Hence why labelling should be permitted, to allow customers the choice rather than allowing companies to engage in fraudulent marketing.

    • Hey shanti
      All of the fruit which is seedless is Gm food,corn flakes, cheerios, all kellogs are gm, Nestlé gm, all sold in Irish shops.ireland is now growing gm spuds. If our food contains gm ingredients it should be labelled but it’s not so we don’t know.

  • I got ill last Christmas, and am still recovering somewhat. I have had to change my diet because of it and I cannot agree with this lady more, however, I find it disappointing she did not name sugar once in the piece. Irish people eat way too much sugar, it’s only since I stopped eating sugar that I have noticed how hard it is to avoid it and how much of it is actually consumed! It’s frightening!

    Reply
    • Add to that the fact that Low Fat products typically contain more sugar but are marketed as a healthy option!

      Reply
    • Yip, and to top that off, processed organic food is generally laced with sugar. I eat a lot of unrefined organic produce now, but ppl need to be diligent with checking ingredients of processed foods, regardless of what the label says – proof; check out the sugar content in organic baked beans!

      Reply
    • Yup, fats aren’t all that bad for you provided – like anything else, they are consumed in moderation, and unprocessed. People avoiding fats are also avoiding vitamins A, D, E and K. They are avoiding essential fatty acids (the omega fats), the brains preferred source of fuel, and they will notice that their skin, hair and nails will become brittle and dry.

      Then there’s the no sugar option – aspartame, sodium saccharin, Sucralose, and Acesulfame K.. Yeah – because I was designed to run on laboratory chemicals..

      Moderation is everything when it comes to diet, and sadly humans are prone to extremes.. They hear something is bad in large amounts and just hear “it’s bad”, they then endeavour to cut it out altogether often leading them to avoid a whole category of food (eg, fats or carbohydrates). On the flipside they hear something is healthy and go overboard on it. The key is in the mantra, “a healthy, BALANCED diet”.

    • Totally agree Shanti, but I have to say it drives me nuts hearing people say fat is worse than sugar! Every body needs a healthy amount of fats, sugar is something our bodies just do not need! I just have a thing about sugar to be honest! It’s total crap that does nothing good for us only rot teeth, put weight on you and cause diseases!

      Reply
    • With regards straight glucose and HFCS I totally agree. Sugar is a pretty vague term though, fruit is pretty much all sugar, but as it’s fructose it affects the body in a different way. On the plus side it doesn’t affect blood sugar levels as badly, because it is sent straight to the liver to be digested. The downside is, if you eat too much the liver gets overloaded and starts storing it as glycogen and that leads to fatty liver – not good.

      But yes – we definitely NEED a certain amount of fats – from polyunsaturated, monounsaturated as well as saturated sources. But as I said already – moderation is key. No matter how healthy something is – too much of it will not be good for you. Even water.

    • “sugar is something our bodies just do not need! ”

      Not true.. your body needs some sort of sugar to fuel itself and your brain. If you deprive yourself of sugar your body will break down carbs to create its own sugars. The best source of sugar is naturally occurring in fruit and vegetables.
      That’s why you have blood sugar levels,

      Reply
    • I know that Simon, my point was probably not expressed well. Your body converts carbs to glucose, which is a type of sugar. So no you do not need to intake sugar, even in fruit for that matter, as much of the food we intake converts to sugars internally.

      Reply
    • Saying your body will do it if it doesn’t get sugar is infactual, it does it anyway. Diabetics for example have to watch carbs as much if not more than sugar for example. Carbs are broken into sugar internally irrespective!

      Seems like not that long ago I read a good example of just that…

  • Being a diabetic (type 2) and having Haemachromatosis (spelling ?) I have to avoid cereals or anything that is fortified with iron.
    I eat a lot of fish and believe it or not potato skins (lovely under the grill ) and veg.
    Works for me along with exercise and keeps the HBA1C down to less than 5.
    I totally agree that there are a huge amount of “experts” giving their opinion.
    Common sense should be involved as well.

  • Some of the worst nutritional advice I’ve heard has come from dieticians. Like some doctors the advice given is driven by the money they can make from promoting certain products.

    Reply
  • I am wary of someone claiming to have clinical knowledge of human nutrition who reckons we shouldn’t eat saturated fats.

    The average recommended fats for an adult is 70g, of which 20g should come from saturates. EXCESSIVE saturated fats are thought to be bad, but this article gives the impression that they are just bad full stop (“encouraging people to eat saturated fat” was mentioned as bad diet advice).

    As for dairy, there are many people who cannot process dairy products, possibly because we are the only species that continues to drink milk after weaning (and another species milk at that).
    And the wheat – that’s a vague term, refined wheat is not good for you – wholegrain is a different story, but no distinction was made, I will assume we are not talking about coeliacs or people allergic to gluten..

    Is this representative of the knowledge of someone who will be on the register?

    Reply
    • It is safe to assume that a short article on The Journal is not equivalent to a private appointment with a dietician.

      A short article cannot possibly discuss the myriad intricacies of health and diet. It can only ever give a brief synopsis and a very, very brief one at that. Expecting such a short article to go to such detail (i.e. subgroups of wheat) is silly and off-topic.

      Reply
    • I wasn’t talking about “subgroups of wheat”.

      Wholegrain is just that, the whole grain. The way it was intended. It is a complex carbohydrate, a source of vitamins, oil and fibre.
      When this is milled it is called “wholemeal wheat flour”, and retains most of its nutritional value.
      Bread made with this flour is known as “brown” bread.

      White bread (and pasta and cakes and biscuits etc) is made from the same stuff, the difference is the wheat has been *refined*. This means;
      • the outer husk – which contains all the good stuff, has been removed, exposing the gluten inside (this causes some people problems)
      • it has been bleached white using alloxan (for the record, alloxan is the stuff they inject into lab animals to induce diabetes, it is toxic to the beta cells that make insulin in the pancreas)
      • it no longer has any real nutritional value, and is what is referred to as empty calories. It’s equivalent to sugar – in fact technically, that’s what it is classed as.
      This is what is known as “wheat flour”, not “wholemeal wheat flour” or “wholegrain wheat flour”, but they are all made from the same stuff.

      Perhaps this will explain what I meant? There is a huge nutritional difference between the two – and people get duped very easily. Check out the quantitive ingredients list on the supposed “wholemeal” or “wholegrain” sliced pans.. Many list “wheat flour” (white) as the main ingredient, meaning that it’s really just a white pan with some brown in it, but costs more anyway.

    • I seriously doubt that you did not know what I meant by “subgroups of wheat”. Lets not get into a pedantic, semantic debate about something typed on a phone in a hurry. I (and most other people) are aware of the nutritional differences between unrefined and refined wheat.

      Do you genuinely feel that the above article should feature the level of detail in your reply to me?

      I’d feel for your editor if you were asked to write a short piece around 1000-1500 words.

      Reply
    • Actually the reason I said it is because no, not everyone realises there’s a difference. And while they may be advised to avoid refined wheat – this doesn’t mean they should avoid wholegrain (unless they are coeliac).

      It’s the same as people avoiding fats because they’re afraid that fat will make them fat – humans, particularly humans with limited nutritional knowledge are prone to extremes where they will cut entire subgroups of food out without truly understanding why – or how dangerous it can be.

      I’m sorry you failed to understand the concern I was expressing.

    • You actually seem to be the one failing to see my point. I am not actually engaging with you in a discussion on healthy eating and/or the knowledge of this in the wider public. Are there issues about knowledge of healthy eating? Of course. That’s not something we need Sherlock Holmes on hand to solve. But that is not my point, nor has it been my point. My posts have continually revolved around pointing out that you expect the writer of this article to include far, far more detail than is possible. A brief overview can only ever be just that.

      As I said in my first post, a short article cannot cover the range of topics that a one-on-one appointment with a dietician can cover. You don’t seem to have engaged with this primary point of discussion in my posts. Instead you write more condescending off topic posts.

  • This won’t help a lot. I have had to have lots of advice recently from trained nutritionists/ dieticians in a variety of hospitals ….they contradicted each other in relation to many food items e.g. low fat spread vs benecol vs unsalted butter or salt vs no salt vs lo salt…..etc.

  • Kids are given way way too many sugary sweets and juice drinks.
    Only purchase ‘not from concentrate’ juices. Free from additives, slightly more expensive than the ‘from concentrate’ crap juice drinks and are full of fake sugars and flavours.
    Why not chop up diff fruits in different shapes and colours and present to a child and make it exciting for them.
    Also processed packets of ham and cheese , dot get me started on the dangers and the low fat butter, yoghurts etc. full fat are safer in moderation.

  • Actually salt is the real public enemy number one. I have given it up and am amazed at how much is in the most common food products….listed as ‘sodium’ on current packaging but will have to be legally listed as ‘salt’ from 2013.

    • By the way, i use salt to kill the weeds – that tells you all you need to know.

    • “Salt”, aside from being a very vague term, is not necessarily bad for you. It is just that people use too much.

      Sodium and Potassium and a few other trace minerals all count as salts. They are what is known as electrolytes, they help with nerve function, help transport nutrients into the cell, and maintain the water balance – which is critical to hydration. This is why you get a saline drip when you are dehydrated rather than pure water.
      Sodium and potassium need to be in balance. It is possible to become deficient in either – it’s just quite rare given that most foods contain one or the other.

      So while *excessive* salt (and by that I mean added salt – specifically common table salt, sodium chloride) is indeed bad for you, the body does actually require *some* salts.
      Again it’s down to us humans being really bad at the whole moderation thing!

  • Plenty of chocolate!

    Reply
    • Actually, real chocolate, as in 80%+ cocoa solids without a load of added sugar is quite good for you. Cocoa beans even better. It’s just very bitter, so most people don’t like it.
      It’s a very good source of magnesium, which is required for over 2000 processes in the body.

      The stuff most people call chocolate isn’t really chocolate, and I remember about 10 or 15 years ago there was talk of it being renamed as the amount of cocoa solids in your average milk chocolate bar is negligible. Even in commercial “dark” chocolate it’s rarely above 40%.

  • It’s not “You are what you eat” rather “Eat what you are” i.e. Fat & Protein. Nutritionists have been giving the wrong advice for 40 years now. Fat doesn’t make you fat, it’s the that carbohydrates make you fat.

  • Nutritionists are the fakers, dietitians are real and are already registered as part of the HSE.
