Why it is hard to cut back sugar

By now you've gotten the memo that cutting back on sugar is one of the best things you can do for your health.  Beyond adding empty calories and spiking blood glucose, which can contribute to weight gain and myriad associated health issues, eating sugar can increase your risk of dying from a heart attack. A major study published in JAMA Internal Medicine in 2014 found that people who ate close to 20 per cent of their daily calories from added sugar had a whopping 38 per cent higher risk of dying from heart disease than those who ate half as much.

(To be clear, I am talking about added, refined sugar here — the concentrated sweetener put into foods, as opposed to the sugars inherent in whole fruits and dairy. Because those foods are naturally "packaged" with water, fibre and other nutrients, they do not have the same negative effect on your health. In fact, most of us should be eating more of them.)

OK already. You are convinced that you need to cut back on added sweeteners; you may have even made it your New Year's resolution. But if you have discovered that sugar has an unexpected hold on you and you can't seem to resist it, you are not alone, and it is not necessarily about a lack of willpower. The game is rigged in sugar's favour for three main reasons: We are born to like it, it is everywhere, and it is addictive.

Why we love it 

Humans have an inborn preference for sweet. We taste sugar and our pleasure sensors fire like crazy. When our ancestors were running around in loincloths, that genetic predisposition helped them survive, as sweet foods provided a valuable source of energy and were less likely to be poisonous than bitter foods. Concentrated sources of sugar, such as wild honey, were a rare find and tough to get (and it meant facing a hive full of bees).

Now, sugar is everywhere. It's in the obvious places such as lollies, cookies and soft drinks, but it's also in cereal, yoghurt, bread, crackers, dressings, condiments and prepared meals. Our ancestors might find it odd that now we have to hunt to find a packaged food that doesn't have added sugar.

Code names for sugar

You'd have to be a sleuth to uncover added sugars on food labels; they are not listed separately but lumped together with sugar inherent in food, so plain milk and fruit unfairly seem "sugary". (Listing added sugars separately is a proposed change for the upcoming revision of the nutrition facts label. Fingers crossed.)

And sugar has many guises, among them agave syrup, brown sugar, cane sugar, corn syrup, evaporated cane juice, fructose, fruit juice concentrate, glucose, high-fructose corn syrup, honey, malt syrup, maple syrup, molasses, raw sugar, sucrose, syrup and more. Although some of these may be less processed than others and offer a modicum of antioxidants and minerals, they all count as added sweeteners.

It's like a drug 

On top of that, more and more research reveals that sugar is addictive, not just in the loose, vernacular sense, but in the same way drugs are addictive. Several animal studies show that sugar stimulates the brain and causes dependence and withdrawal the same way addictive drugs do.

A new study from Duke University published in the journal Neuron showed that mice who had formed a sugar habit had marked changes in the part of their brain that controls compulsive behaviour such as drug addictions.

A study published in PLOS One in 2007 demonstrated that cocaine-addicted rats preferred intensely sweetened water to the drug when given the option, and another published in 2015 showed that processed foods, including those that have a high glycaemic load (quickly release sugar into your bloodstream), are linked with addictive-like eating behaviours.

This doesn't mean you have to shun sugar altogether or that bringing cupcakes to school for your child's birthday is akin to giving cocaine to a bunch of fourth-graders. But it does reveal the depth of the struggle many people have with sugar and offers insight into how to manage it. It may be helpful to think of sugar as we do alcohol: Most people can enjoy it in moderation without harm, but it could be a danger when overdone or to those with addictive tendencies. With that in mind, here are several strategies for getting the upper hand on the sweet stuff:
