Oh how sweet it is to indulge in some sugar-packed snacks. The engrained and enjoyable human preference for sugar has previously served to help keep us alive. But with modern food manufacturing, this simple carbohydrate is currently associated with weight gain, inflammation and a host of health issues. Time to take a spoonful dose of science and taste the truth about sugar.
Sugar is a simple form of carbohydrate, which is a macronutrient. Natural sugars are the ones found in whole foods such as fruit (fructose) and dairy products (lactose). Fruit contains fiber and dairy contains protein and fat which help slow how fast the sugar reaches our bloodstream. It's better to delay absorption in order to prevent blood sugar spikes (1).
Refined sugar is extracted and purified from sugar cane or sugar beet (2). It’s typically found as sucrose (combination of glucose and fructose). This process results in the familiar white granules or syrups that are added to our common foods and drinks such as soda, cereal, baked goods, and candy.
Food manufacturers also chemically create sweeteners such as high-fructose corn syrup to sneak into beverages and common foods. The problem with these highly processed foods is that they have little nutritional value and have been linked to weight gain and disease when eaten in excess (3).
The carbohydrates we eat from foods such as grains, fruits, legumes (beans, peas, lentils) and vegetables get broken down into a simple form called glucose. Glucose is our brain and muscles’ preferred source of energy. The brain uses about 20% of the glucose in our bodies (4).
Maintaining glucose levels within a normal range is important for keeping your body functioning and healthy. When we don’t get enough carbohydrates from foods or during times of exercise, our body will convert glucose from protein or fat stores.
Our bodies digest and absorb refined sugar very differently than whole food sources. The fiber and nutrients in whole foods help slow the absorption, resulting in more balanced “hills” of blood sugar and energy levels throughout the day.
When we consume sugar-rich foods, especially on an empty stomach, it can cause drastic peaks and valleys. In the short term, we can feel tired and crave more sweets. In the long-term it can increase the risk of diabetes and other blood sugar related conditions.
More research is coming out on how an excessive intake of added refined sugar can have an impact on weight gain and these related diseases:
However, if you eat sugary foods in moderation once in a while they will not cause you any harm.
The average American eats about 20 teaspoons of sugar every day, while the American Heart Association recommends only 6 teaspoons for women and 9 for men each day (9). Especially if you’re prone to one of the above conditions, it’s a good idea to watch your sugar intake.
Added sugar can be hiding in many surprising foods. Unfortunately, we can’t always easily tell when a food has natural or added sugar. Food manufacturers are not currently required to list added sugar separately on the food label. To spot the added sugar, check out the ingredient list.
If you’re hooked on the sweet stuff, and concerned about weight gain or have a family history disease, you may want to consider cutting back. Consider your personal diet preference and whether its best to go cold turkey with a sugar detox, or slow and steady with these tips:
Getting sugar from natural sources such as fruit, requires chewing and digesting, helping to moderate the total amount you consume. Easily cut your sugar consumption by making your own naturally sweetened snacks such as this sweet and spicy gem:
