Just how did so much sugar end up in our food?

A growing collection of documentaries depict the epidemic of obesity and chronic disease as a result of our food choices. For example, there is Supersize MeSuper Juice MeThe Men Who Made Us FatFood Matters; and most recently That Sugar Film. Some of these are criticised due to the lack of ‘lab’ style data, but the results and messages seem very consistent. Junk (processed) food makes us sick and healthy food helps to restore and maintain our health. This picture is increasingly being supported by research.

The first way to take charge of our health is to become aware of the way in which the food industry works and how such large quantities of sugar have crept into most packaged products on supermarket shelves, as well as fast food restaurants.

The three part documentary aired in 2012, ‘The Men that Made us Fat’ (by Jacques Peretti), discusses a more political cause for what it terms ‘the obesity epidemic’. Just to recap, or for those that haven’t seen it, key factors in the rise of obesity over the past forty years according to this documentary are as follows:

  •  In the 1970s in America there was a push towards maximum agricultural production, many small farms were lost to industrialised farming methods. Corn was particularly abundant.
  • It was discovered (by a Japanese scientist) that corn could be converted to a very sweet syrup, called High Fructose Corn Syrup (HFCS), with a higher ratio of fructose to glucose than table sugar, as well as being sweeter and 1/3 cheaper than sugar. This was then, for economic reasons quickly taken up as a sugar replacement for many food and beverage companies, substantially increasing profit margins. This product is now ubiquitous in processed foods and soft drinks.
  • Simultaneously in the UK, the concept of ‘snacking’ was introduced, with marketing campaigns encouraging snacking on sugary bars in between meals, increasing not only calorie intake but also dramatically increasing proportion of sugar consumed by individuals.
  • The prevalence of heart disease during the 1970s was blamed on high saturated fats. The food industry quickly saw an opportunity to produce and market ‘low fat’ foods, altering the saturated fat to transfat by hydrogenation processes (now known to be far more dangerous than saturated fat) and adding sugar to compensate for compromised taste. Obesity continued to escalate, as did Cardio Vascular Disease and other chronic diseases.
  • Professor John Yudkin vehemently believed sugar played a bigger part in disease than fats. He published a book, in 1972, called ‘Pure, White and Deadly’. Professor Yudkin was discredited for his work and his findings dismissed.
  • Portion sizes increased as a marketing tool packaged as ‘value’. Low cost nutrient devoid foods such as popcorn, fries, soda came in a ‘jumbo’ size for relatively small price increase. This resulted in increased profit margins for food companies and the population became accustomed to larger portions. Then came the concept of ‘bundling’ again pitched as value as they added in yet more high sugar, low nutrient foods.
  • Mounting evidence that excess sugar in processed foods was being presented to Governments but was generally ignored.
  • A reported prepared by JP Morgan in 2003 warned investors that manufacturers of unhealthy foods were vulnerable to financial losses. This certainly motivated people into action, but the concerns were profits and shareholdings, not public health.
  • The increasing public interest in health led food manufacturers to label accordingly, perhaps fortified with vitamins, but there was not a reduction in sugar. In the UK the food industry successfully fought a proposal for mandatory ‘traffic light labelling’ to help consumers readily discern high sugar, calorie and fat meals. This became a voluntary measure taken up by Sainsbury’s but declined by Tesco’s. It seemed the risk of people finding out a food was unhealthy and then choosing not to buy it was too high.

A comment made on this documentary that struck was that one of the great strengths of supermarkets was their responsiveness to consumer demand.

That puts us back in charge.

The only way this situation will be reversed is through education and through us as individuals making different choices. Whilst it is not difficult to see that the Government and Food Industry bear considerable responsibility for the health crisis we currently face, with so many competing interests, it is difficult to see a clear solution. The food companies employ millions of people, are answerable to their shareholders and of course enjoy enormous profits. Our health is a long way down the list of priorities. Therefore, it seems that whilst the Government and Food Industry may have created this situation, only we can fix it.

Another key figure in the growing awareness of the dangers of sugar is Professor Robert Lustig who has posted a number of informative lectures on YouTube. In 2009 he posted a lecture called “Sugar: The Bitter Truth” which has had over 5 million views. It is highly recommended.

Professor Lustig describes sugar as a toxin, akin to tobacco and alcohol and says it should come with warnings and taxes. He goes further than calories though, citing fructose, in particular, as a poison when consumed in excess, due to its ability to switch off satiety centres in the brain, interfere with leptin and other hormones associated with negative feedback control. It is important to note that when fructose occurs in whole foods, such as fruit and vegetables, it is not dangerous as the fibre and other nutrients reduce the absorption and help metabolise this substance. Professor Lustig’s lectures give clear scientific explanations of the different ways sugars behave in the body and why not all calories are the same.

The point of calories not being the same is also referred to in the recent popular documentary, That Sugar Film. During this experiment Damon Gameau replaces his usual diet, consisting of whole foods, with packaged/processed foods which are marketed as healthy, with the intention of matching the estimated daily sugar intake of Australian people, being 42 teaspoons per day. Gameau claimed that his calorie intake didn’t change, but the type of calories did. The outcome was predictably that he gained weight, experienced mood swings, fatigue and developed signs of fatty liver through raised liver enzymes, particularly ALT (Alanine Transaminase). Whilst I would not consider any of the foods eaten by Damon Gameau in the documentary to be healthy, it is disturbing that a number of people do. The results were by no means a shock and to go back to our initial point, the evidence shown in this growing collection of documentaries appears very consistent. Nutrient poor, fibre poor, sugar laden foods are harmful and make us sick.

Over recent years, there has been an enormous amount of attention given to the dangers of sugar, somewhat vindicating to those of us who have been saying this for decades. However demonising of all sugars and conflicting information may be confusing. We do, after all, require a constant supply of glucose to function, with our brains being particularly dependent on this substance. Sugars do occur naturally in foods, or are converted from foods (carbohydrates). Certainly added sugars should be minimised and the biggest source of these added sugars are hidden in processed foods.

To simplify and sum up, there are very few people who would argue with the fact that the western world consumes an excessive amount of sugar, although some may be shocked at just how much. If the sugar comes in it’s natural form, that is fruit and vegetables, and is consumed as a whole food it is unlikely to be a problem for most people. The nutrients, fibre and sugars will be utilised by the body and satiety will prevent overconsumption. If the sugars (whether in the form of sucrose or HFCS) are added to foods with few nutrients and little to no fibre, blood sugar will spike, the liver will struggle to metabolise the fructose portion, satiety will not occur through disruption of hormones such as leptin and all of these factors will encourage over eating whilst simultaneously leaving the body and brain undernourished. This is why a mango is different to a mars bar and dates are different to coca cola.

My concern about these suggestions is that during a lapse of willpower, which is highly likely in any deprivation type diet, people may think that if it is all the same they may as well have a mars bar or coke, when they would be much better to satisfy their cravings with a mango or a date.
