Sugar sweet and dangerous

Sugar is one of the most popular and ubiquitous substances in our diets today, both sweet and dangerous.

Sugar is one of the most popular and ubiquitous substances in our diets today, both sweet and dangerous. At times its presence is obvious but sometimes, it’s not easy to discern or to necessarily taste. Nonetheless you’ve probably seen its effects in action.

You may have noticed the behaviour of young children, especially the ones that go a bit crazy at birthday parties, after they’ve had some lollies or other sugar-laden foods.

You may also know that high-sugar and not high-fat is often now considered to be the main contributory factor to the overweight/obesity issue. To compensate for the loss of taste as flavoursome fat was removed from masses of processed products, manufacturers ramped-up the levels of sugar.

But that’s not all. Excess sugar consumption has also been implicated in:

  • Tooth decay.
  • Type 2 Diabetes
  • Cardiovascular disease
  • IBS
  • Joint disease
  • Cancer
  • Liver disease
  • Blood sugar disorders
  • PCOS
  • Acne
  • Depression
  • Other mental health disorders

But before we condemn all sugar, we need to bear in mind that there are many different forms of sugar.

3 common sugars

Definitely the highly processed sugars that we use to make things taste sweet such as white and brown sugar, high fructose corn syrup, dextrose, maltodextrin and many of its other pseudonyms are the ones to keep to a minimum.  Often these are found in refined, packaged foods including confectionary, bakery, cereals and desserts; sugar also pops up in peanut butter, pasta sauces, bread, ready meals and hazelnut spreads.

Artificial sugars or sweeteners such as aspartame, saccharin and sucralose have been linked to their own set of health issues and again sneak into a wide range of foods and drinks as a sugar replacement, to cut down on calories.

There is also some discussion as to whether or not these sweeteners activate the food-reward system that ensures you feel satisfied after eating; hence it may lead to over-eating as the brain seeks to fulfil its needs.

These include whole fruits and vegetables – particularly higher in fruits such as bananas and mangoes and root veggies such as sweet potato and carrots; these natural sources of sugar, whilst sweet are also good suppliers of vitamins, minerals, antioxidants and fibre.

Fruit juice isn’t the same as whole fruit as it lacks fibre; it has got as much sugar as many classical sugar drinks. It is also absorbed very fast so by the time it gets to your stomach your body doesn’t know whether it’s Coca-Cola or orange juice!

I also include honey under this section because it contains many beneficial compounds, especially if it is sourced locally and not subjected to high temperatures.  It may be taken internally for its healing anti-microbial properties or applied topically for its wound-healing attributes.

There are other sugars that whilst derived from natural sources, have been so processed that their health benefits are perhaps questionable, for example rice syrup.

3 thoughts about sugar


Firstly, our cavemen ancestors only really had access to an abundance of natural sugar during spring and summer, which they ate to build up a fat layer to see them through the winter when there was a shortage of them.

In winter they would be less active and use the stored fat as energy.

Nowadays though, our bodies are accustomed to the availability of sugar all year round and the problem is that winter never comes.  So hence our bodies get fatter and sicker, for it’s endless summer.

Reward system

Secondly, from an early age we associate sweet foods with pleasure foods; as soon as we eat something sweet our brain responds by activating the reward system.  When the reward system is activated by sugar we get a rush of brain chemicals that gives us a sense of wellbeing.  As babies we are fed our mother’s milk which is naturally sweet and rich in tryptophan which makes serotonin, the feel-good hormone.

As kids, we may have been told that if we ate our dinner we would get dessert or have been given lollies for being well-behaved.  Thus, a seed is sown linking sweet foods to feeling good.

Sports link

Thirdly, it has become acceptable for big-name companies to spruik their sugar-laden drinks/foods alongside prominent sporting events to align their product with a positive health association. At the 2012 London Olympics Coca Cola was the official soft drinks provider.

The sugar problem

Our bodies are not designed to handle the vast quantities of sugar that is in our standard diet today; our cavemen ancestors only had access to fructose in whole fruits, in amounts that were relatively dilute.

The complications set in when we discovered how to turn real foods which contained fibre, water and other nutrients into pure sources of sugars, for example by refining sugarcane into table sugar.  And then we started to consume this and the other sugars in excess.  Often, the more we eat, the more we crave and so the vicious cycle begins.

Knowing what to look out for on food labels

  • Avoid any food or drink that lists sugar as the first or second ingredient;
  • Dairy contains 4.7% lactose, the milk sugar that doesn’t contain fructose; dairy products with more than this may well have added sugar.
  • Shun products with more than 3 – 6g of sugar per 100g
  • Sugar may be present in 1 of its other guises, dextrose, agave, high-fructose corn syrup etc
  • Sugar is often added to cook-in sauces, salad dressings, mayonnaise, yoghurts, flavoured milks, marinades and the like.
