Say the word “sugar” and most people picture the familiar white granular stuff many of us have in a sugar bowl at home. But what is sugar exactly?
Table sugar is just one form of sugar that we get in the diet. Sugars are carbohydrates, and they exist naturally in different forms and in all kinds of foods. The granulated sugar that you might sprinkle on your cereal is called sucrose, which is produced primarily by extracting the sugar from sugar beets or sugar cane, although it is present in lots of other plant foods, too. The primary sugar in fruits is called fructose, and there is a naturally occurring sugar in milk called lactose. When you consume a fruit, a vegetable or
a dairy product, you can’t avoid consuming the natural sugar that these foods contain.
All sugars ultimately end up in the bloodstream in the form of glucose, which is the form of sugar that our body prefers to use for energy. While sugars in foods end up as glucose in the bloodstream, so do the end-products of the digestion of all carbohydrate-rich foods like fruits, vegetables and starchy foods.
The concern about sugar intake from added sugars (not the naturally occurring ones) has mostly to do with the fact that they are considered to be “empty calories”–that is, sugar provides calories (which the body uses for energy) but no vitamins or minerals. So, if you consume a lot of sugary foods instead of
healthier items, you are shortchanging yourself by not getting enough of the vitamins, minerals, fiber and healthy phytonutrients that carbohydrate-rich natural foods contain.
We eat a lot of sugar–even in foods that don’t taste sweet. Aside from the obvious items like sodas, fruit drinks, sweetened cereals and desserts, sugar–in one form or another–finds its way into condiments, soups, breads and even savory snacks like chips. The primary health hazard of eating too much sugar is tooth decay. The bacteria that live in your mouth can convert sugars into an acid that can destroy tooth enamel. Foods that are sweet and sticky, like fruit snacks or gummy candies, are particularly a problem since the sugar stays in contact with the teeth.
Does sugar make you fat? Certainly sugar adds extra calories to the diet, and extra calories mean extra weight. Most studies have focused on soda consumption, and several have concluded that as soda consumption increases, so does the risk of obesity. Part of the problem with beverages is that they don’t fill us up–so we can consume a lot of calories in these sweet liquids and still consume regular solid foods, too, before we feel full.
The other issue is that many foods that are high in added sugars are also high in fats and calories–cakes, pastries, ice cream and candy bars are just some of the sweet foods we eat that are loaded down with fat and calories. Food manufacturers are more than happy to accommodate America’s sweet tooth–sugar is inexpensive and adds a lot of taste to foods. To know how much sugar you are eating, it’s important to understand that many forms of sugar are added to foods. By reading the label, you may not realize how much sugar a food really contains.
Here are some other forms of sugar that you might see on a label: sucrose, fructose, glucose, dextrose, lactose, maltose, invert sugar, raw sugar, turbinado sugar, brown sugar, cane sugar, brown rice syrup, fruit juice concentrate, confectioner’s sugar, maltodextrin, corn syrup, high-fructose corn syrup, honey, maple
syrup and molasses.
One popular breakfast cereal marketed to children has the following ingredients: corn, sugar, corn syrup, modified cornstarch, canola oil and high-fructose corn syrup, followed by some vitamins, minerals, and artificial colors and flavors. This cereal isn’t much more than a bowl of sugar, oil and starch.
When you look at a food label, the sugar content is listed–in grams per serving–just under the total carbohydrate listing. But this includes all sugars in the food including natural sugars, so it can be deceptive. For instance, a bran cereal with no added sugar but with raisins in it might look as high in sugar as a sugary kid’s cereal. But there is a big difference in the nutritional value of the two foods, since one might contain only the natural sugar from the fruit, while the kid’s cereal will contain all added sugar.
How can you reduce your sugar intake? Try to obtain your sugars naturally–which should be primarily from fresh, whole fruit.
• Fruit juices, even if they are 100 percent fruit juice, are all-natural sugar but they are very high in calories–it’s best to avoid beverages with high calories, including fruit juices, sodas, lemonade and other sweetened beverages. Learn to enjoy your iced tea for its natural flavor, rather than for the flavor of the sugar that you pour into the glass.
• Rather than adding syrup or honey to foods like waffles or pancakes, try topping them with sliced fresh fruit and a dollop of vanilla yogurt.
• Look for whole-grain cereals without added sugars, and top with sliced bananas, berries or other fruit that appeals to you. This applies to both cold cereals and hot. Oatmeal is delicious with some mashed banana stirred in for sweetness.
• Keep healthy snacks around, like whole fruits, cut vegetables, whole-grain crackers, low-fat yogurt and low-fat cheese, so you won’t be tempted to eat sweets instead.
• Help your kids develop healthier habits–if they are old enough to read labels, give them a list of all the names for sugar and ask them to become “sugar detectives.” They will enjoy finding the hidden sources of sugar in foods, and it will help to educate them as to how much sugar is added– sometimes where you least expect it.
• Instead of baked goods for desserts, try fresh fruit with a bit of chocolate syrup. One great trick is to take ripe bananas, peel and place them on a foil-lined tray in the freezer. Frozen bananas taste
just like ice cream and will satisfy your sweet tooth for significantly fewer calories.
• If you add sugar to cereals, beverages and fruits routinely, try to gradually reduce the amount you use. You may not really know the true flavor of these foods because you have “masked” the flavor with sugar. Fresh fruits in season should be deliciously sweet–no added sugar necessary.
