Sugar is regarded as a villain; sometimes thought of as a possible cause of certain cancers and other ills, and manufacturers often disguise sugar to make it more acceptable.
Livestrong, the US Cancer charity, warns ”
Sugar is one of the most common food additives used to improve the taste of foods and beverages and prolong the shelf-life of countless packaged food products. And all that sugar is hiding in some pretty unexpected places. (Case in point: Did you know that, cup for cup, there’s more sugar in ketchup than vanilla ice cream?)
Different types of sweeteners, substituted for sugar, can be tagged ‘sugar-free’, but still contain calories.
To help sort out differences, Livestrong has some pretty intelligent and easy-to-understand information:
“Sugar substitutes fall into one of two categories: natural sweeteners (which include sugar alcohols like erythritol) and non-nutritive sweeteners like sucralose (aka Splenda)”. A tablespoon of ‘ordinary’ sugar contains 40 calories
- Women should limit sugar intake to no more than 6 teaspoons per day, which provides about 100 calories.
- Men should limit sugar intake to no more than 9 teaspoons, or about 150 calories. (Men need more sugar because they have a higher percentage of lean body mass, which correlates to a higher metabolic rate)..
If you are savvy, you can take in fewer calories without losing nutrients in the process. Drink plain water/fizzy water instead of sweetened drinks; choose low-sugar jams and syrups; buy canned fruit packed in water rather than syrup; reach for salsa, mustard or hot sauce over ketchup and barbecue sauce and opt for low-sugar breakfast cereals.
Livestrong are very patient-focussed, and have published a list of the major ‘sugar’ type foods, their
Handy guide to hidden sugars and alternatives
With a GI index of 42, dates can sweeten baked goods and smoothies — but note that a little can go a long way in terms of sweetness, especially when using dried dates. Average calories: 20 per date (7.1g)
Maple syrup comes from boiling the sap from maple trees. The color of the syrup is a result of when the sap was tapped in the season; early season maple sap produces lighter syrup and later in the season, darker syrup.
N.B. many maple syrup products are blended with corn syrup and/or cane sugar syrup because maple syrup itself is expensive. Its glycemic index is 54, and it contains higher levels of minerals and fewer calories than honey. Calories: 52 per tbsp
Honey is derived from the nectar bees create in their honeycombs. Sugars in honey are 40 percent fructose , 35 percent glucose and two percent sucrose. While honey can be used in baking, it should not replace sugar 1:1, and the liquid in the recipe must be adjusted due to the water content in honey. Honey also has a more pronounced flavour than sugar.
Its GI is 61, while table sugar is at 58, but it may offer some extra minerals, such as zinc and selenium. Calories: 64 per tbsp
The glycemic index for coconut palm sugar is 35 because it is mainly sucrose with small amounts of fructose and glucose as well as inulin (a fiber that acts as a prebiotic), nutrients and antioxidants.Calories: 45 per tbsp
Agave nectar comes from the succulent plant agave from Mexico. Agave nectar is 90 percent fructose, while high-fructose corn syrup is 55 percent fructose.
Agave nectar is often used as a substitute for honey for vegans; however, it is much sweeter than honey, though, like coconut palm sugar, its GI is lower, at 15. Since it tastes very sweet, less is generally used, which is why some claim it is healthier. Yet because it still contains a high level of fructose, the level of healthiness in the long term is debatable. Calories: 60 per tbsp
Stevia comes from the leaves of the South American plant Stevia rebaudiana, which is 200 to 300 times sweeter than sucrose, but can be bitter with an astringent or metallic aftertaste. It is a newer sweetener but has been used in countries, such as Venezuela, Brazil and Colombia for more than a thousand years. The glycemic index of stevia is 0. Calories: 0
Sugar alcohols are not carbohydrates like sugar is. Sugar alcohol can be found naturally in produce, but most packaged varieties have been created in the lab. These alcohols are 20 percent to 100 percent as sweet as sucrose but are not digested by intestinal enzymes, which is why they have fewer calories. They’re used in diet foods because of their ability to be slowly absorbed and because they do not contribute many additional calories.
The glycemic index for sugar alcohols is much lower than others (for example, xylitol’s is 7). Calories in xylitol: 30 per tbsp; calories in erythritol: 2.4 per tbsp; calories in sorbitol: 36 per tbsp
Brown rice syrup is a viscous liquid derived from brown rice treated with enzymes to break down the starches. Not as sweet as white sugar, it has a slight butterscotch flavour.
Due to it containing about 50% complex carbohydrates and 3% glucose, rather than only simple carbohydrates, its sugars are released more slowly into the bloodstream, creating a less visible spike in blood glucose.
However, according the “The Essential Good Food Guide” by Margaret Wittenberg, the level of glucose can be adjusted during the manufacturing process, so the glycemic index of the syrup can be dependent on the individual product. Also of note, there have been recent concerns about the levels of arsenic in brown rice because the plant absorbs arsenic from the environment as many plants do, and the hull, which is present in brown rice but not white rice, retains the absorbed arsenic, according to the Mineralogical Society of America.
The FDA has increased its arsenic testing of rice products since 2011 but has yet to release a comprehensive risk assessment; Consumer Reports recommends limiting consumption, especially for children under 12 months. Calories: 75 per tbsp (in the Lundberg brand)
Corn syrups are a byproduct of cornstarch production and are often used in products to reduce the manufacturing cost. While corn syrup is essentially 100 percent glucose, high-fructose corn syrup can be anywhere from about 40 to 90 percent fructose, and because it is a synthetically made sweetener, a monosaccharide, the levels of fructose can be very high, rather than a combination of both fructose and glucose like sucrose.
It has a high sweetening power, it is not as sweet as sugar or agave nectar, so more of it may be used in packaged foods. Fructose moves quicker in the digestive system than glucose, so it may be harder to feel satiation, increasing consumption. The GI of high-fructose corn syrup is similar to that of sucrose. Calories: 53 per tbsp
Despite the controversies, it is not recognized in the body as a carbohydrate and therefore has been deemed as appropriate for patients with diabetes. The glycemic index of sucralose is 0. Calories: Less than 5 per packet of Splenda (1 gram)
Saccharin is 500 times sweeter than sucrose. It is used now in many baked and processed foods, although one of the drawbacks of saccharin for some is its aftertaste. There also has been controversy about the safety after some research on rats, including an FDA-proposed ban in 1977.
Instead, there is a warning label requirement on items containing saccharin now. It may cause cancer, but it appears to be one of the weaker known carcinogens. The GI of saccharin is 0. Calories: Less than 4 per packet of Sweet’N Low (1 gram)
Aspartame is mostly found in soft drinks and is 180 times sweeter than sucrose. The GI index of aspartame is 0. Calories: 4 per gram
British Medical Journal (BMJ)
Recently the BM had a report that sugar intake, including fruit juice, is associated with a higher incidence of cancer. 1 A fundamental question is whether examining a single nutritional villain in isolation is meaningful, rather than acknowledging the need for a wide ranging, varied, and balanced diet?
