Learning About Carbohydrates and Sugars

You have probably seen ads for low-carb foods and diets, but kids and adults need carbohydrates (say: kar-bo-hi-draytz).

Most foods contain carbohydrates, which the body breaks down into simple sugars – the major source of energy for the body.

Two Types of Carbohydrates

There are two major types of carbohydrates in foods: simple and complex.

Simple carbohydrates: These are also called simple sugars. Simple sugars are found in

refined sugars, like the white sugar you’d find in a sugar bowl. If you have a lollipop, you’re

eating simple carbohydrates. But you’ll also find simple sugars in more nutritious foods, such

as fruit and milk. It’s better to get your simple sugars from food like fruit and milk. Why?

Because they contain vitamins, fiber, and important nutrients like calcium. A lollipop does

not.

Complex carbohydrates: These are also called starches. Starches include grain products,

such as bread, crackers, pasta, and rice. As with simple sugars, some complex

carbohydrate foods are better choices than others. Refined (say: ree-find) grains, such as

white flour and white rice, have been processed, which removes nutrients and fiber. But

unrefined grains still contain these vitamins and minerals. Unrefined grains also are rich in

fiber, which helps your digestive system work well. Fiber helps you feel full, so you are less

likely to overeat these foods. That explains why a bowl of oatmeal fills you up better than

sugary candy that has the same amount of calories as the oatmeal.

So which type of carbs should you eat? Both can be part of a healthy diet.

How the Body Uses Carbohydrates

When you eat carbohydrates, the body breaks them down into simple sugars. These sugars

are absorbed into the bloodstream. As the sugar level rises in your body, the pancreas

releases a hormone called insulin. Insulin is needed to move sugar from the blood into the

cells, where the sugar can be used as a source of energy.

When this process goes fast – as with simple sugars – you’re more likely to feel hungry again

soon. When it occurs more slowly, as with a whole-grain food, you’ll be satisfied longer.

These types of complex carbohydrates give you energy over a longer period of time.

The carbohydrates in some foods (mostly those that contain a lot of simple sugars) cause

the blood sugar level to rise more quickly than others. Scientists have been studying

whether eating foods that cause big jumps in blood sugar may be related to health problems

like diabetes and heart disease. You’re probably already on the right track if you are limiting

simple sugars (such as candy) and eating more complex carbohydrates (like vegetables,

oatmeal, and whole-grain wheat bread).

Carbohydrates

Carbohydrates are the body’s most important and readily available source of energy.

Even though they’ve gotten a bad rap in the 2000s and have often been blamed for

the obesity epidemic in America, carbs are a necessary part of a healthy diet for both kids and adults.

The two major forms are:

? simple sugars (simple carbohydrates), are sugars such as fructose, glucose, and

lactose, as well as in nutritious whole fruits

? starches (complex carbohydrates), found in foods such as starchy vegetables, grains,

rice, and breads and cereals

So how, exactly, does the body process carbohydrates and sugar? All carbohydrates are

broken down into simple sugars. These sugars are absorbed into the bloodstream. As the

sugar level rises, the pancreas releases a hormone called insulin, which is needed to move

sugar from the blood into the cells, where the sugar can be used as a source of energy.

The carbohydrates in some foods (mostly those that contain simple sugars and highly

refined grains, such as white flour and white rice) are easily broken down and cause your

child’s blood sugar level to rise quickly. Complex carbohydrates (found in whole grains), on

the other hand, are broken down more slowly, allowing blood sugar to rise more gradually.

Eating a diet that’s high in foods that cause a rapid rise in blood sugar may increase a

person’s risk of developing health problems like diabetes and heart disease, although these

studies have been done mostly in adults.

Despite the recent craze to cut carbs, the bottom line is that not all foods containing

carbohydrates are bad for your child, whether they’re complex, as in whole grains, or simple

carbohydrates, such as those found in fruits. If carbohydrates were such a no-no, we’d have

a huge problem, considering that most foods contain them. But, of course, some

carbohydrate-dense foods are healthier than others.

Good sources of carbohydrates include:

? whole-grain cereals

? brown rice

? whole-grain breads

? fruits

? vegetables

? low-fat dairy

A healthy balanced diet for children over 2 years should include 50% to 60% of the calories

consumed coming from carbohydrates. The key is to make sure that the majority of carbs

kids eat are from good sources and to limit the amount of added sugar in their diet.

“Good” vs. “Bad” Carbs

Carbohydrates have taken a lot of heat in recent years. Why? Because many medical

experts think excess consumption of refined carbohydrates (refined sugars found in foods

and beverages like candy and soda, and refined grains like white rice and white flour, found

in many pastas and breads) have contributed to the dramatic rise of obesity in the United

States.

But how could any one type of food cause such a big problem? Of course, not exercising

and eating larger portions of any foods than we need take the lion’s share of blame for the

obesity epidemic. But the so-called “bad” carbs — sugar and refined foods — tend to be

significant contributors to excess calories. Why? Because they’re easy to get our hands on,

come in large portions, taste good, and aren’t too filling.

People tend to eat more of these refined foods than needed. And, often, foods like colas and

candy provide no required nutrients, so we really don’t need to eat them at all.

But just because refined carbohydrates have received a lot of flak in recent years doesn’t

mean that all simple sugars are bad. Simple carbohydrates found in a lot of very nutritious

foods — like fruits, vegetables, and dairy products, which provide a range of essential

nutrients that support growth and overall health. For example, fresh fruits contain simple

carbs, but they have vitamins and fiber, too.

The 2005 dietary guidelines recommend that Americans eat more unrefined (often called

“good”) carbohydrates by saying that everyone — including kids and teens — should

increase whole-grain consumption and limit their intake of added sugar. For children, at least

half of their grain intake should come from whole grains.

Whole grains certainly sound like the healthy way to go. But what makes them so different

from simple carbohydrates? Whole grains are complex carbohydrates (like brown rice,

oatmeal, and whole-grain breads and cereals) that are:

? broken down more slowly in the body. Whole grains contain all three parts of the

grain (the bran, germ, and endosperm), whereas refined grains are mainly just the

endosperm — and that means more for your body to break down. More to break down

means the breakdown is slower, the carbohydrates enter the body slower, and it’s

easier for your body to regulate them.

? high in fiber. Not just for the senior-citizen crowd, foods that are good sources of fiber

are beneficial because they’re filling and, therefore, discourage overeating. Diets rich in

whole grains protect against diabetes and heart disease. Plus, when combined with

adequate fluid, they help move food through the digestive system to prevent

constipation and may protect against gut cancers.

? packed with other vitamins and minerals. In addition to fiber, whole grains contain

more important vitamins and minerals, including B vitamins, magnesium, and iron.

Unrefined carbohydrates found in whole grains are ideal, refined grain products may be

fortified with folic acid (also called folate), iron, and other nutrients, and as a result may

contain more of these nutrients when compared with whole-grain foods that have not been

fortified.

The actual amount of grains will vary depending on your child’s age, gender, and level of

physical activity. On average, school-age children should eat about 4- to 6-ounce

equivalents from the grain group each day and at least half of these servings should come

from whole grains. All ounce equivalent is like a serving. So one slice of bread, 1 cup of

ready-to-eat cereal, or a half cup of cooked rice, cooked pasta, or hot cereal can be

considered a 1-ounce equivalent.

Sizing Up Sugar

Foods that are high in added sugar (soda, cookies, cake, candy, frozen desserts, and some

fruit drinks) tend to also be high in calories and low in other valuable nutrients. As a result, a

high-sugar diet is often linked with obesity. Eating too many sugary foods can also lead to

tooth decay.

The key to keeping sugar consumption in check is moderation. Added sugar can enhance

the taste of some foods, and a little sugar, particularly if it’s in a food that provides other

important nutrients, such as cereal or yogurt, isn’t going to tip the scale or send your child to

the dentist.

Instead of giving your child foods that are low in nutrients and high in added sugar, offer

healthier choices, such as fruit — a naturally sweet carbohydrate-containing snack that also

contains fiber and vitamins that kids need.

One way to cut down on added sugar is to eliminate soda and other sugar-sweetened

beverages. Not only can drinking sweetened sodas lead to the erosion of the enamel of the

teeth from the acidity and dental cavities (or caries) from the high sugar content, consider

these statistics:

? Each 12-ounce (355-milliliter) serving of a carbonated, sweetened soft drink contains

the equivalent of 10 teaspoons (49 milliliters) of sugar and 150 calories. Sweetened

drinks are the largest source of added sugar in the daily diets of U.S. children.

? Consuming one 12-ounce (355-milliliter) sweetened soft drink per day increases a

child’s risk of obesity.

Instead of soda or juice drinks (which often contain as much added sugar as soft drinks),

offer kids low-fat milk, water, or 100% fruit juice. Although there’s no added sugar in 100%

fruit juice, the calories from the natural sugars found in fruit juice can add up. The American

Academy of Pediatrics (AAP) recommends limiting juice intake to 4–6 ounces (118–177

milliliters) for children under 7 years old, and no more than 8–12 ounces (237–355 milliliters)

of juice for older kids and teens.

Figuring Out Carbs and Sugar

It isn’t always easy to tell which foods are the best choices and which aren’t, just by looking

at the labels. To figure out carbohydrates, look under Nutrition Facts on food labels, where

you’ll find three numbers for total carbohydrate: the total number of carbohydrates, the

amount of dietary fiber, and sugars.

? Total Carbohydrate: This number, listed in grams, combines several types of

carbohydrates: dietary fibers, sugars, and other carbohydrates.

? Dietary Fiber: Listed under Total Carbohydrate, dietary fiber itself has no calories and

is a necessary part of a healthy diet. A high-fiber diet promotes bowel regularity and

can help reduce cholesterol levels.

? Sugars: Also listed under Total Carbohydrate on food labels, sugars are found in most

foods. However, the Nutrition Facts label doesn’t make the distinction between natural

sugars and added sugars. Natural sugars are found in many foods, including fruit and

dairy products. Snack foods, candy, and soda often have large amounts of added

sugars. To find out if a food has added sugar, you need to look at the ingredient list for

sugar, corn syrup or sweetener, dextrose, fructose, honey, or molasses, to name just a

few. Avoid products that have sugar or other sweeteners high on the ingredient list.

Although carbohydrates have just 4 calories per gram, the high sugar content in snack foods

means the calories can add up quickly, and these “empty calories” usually contain few other

nutrients.

Making Carbohydrates Part of a Healthy Diet

Ensuring that kids get a balanced, nutritious diet isn’t as hard as it may seem. Simply make

good carbohydrate choices (whole grains, fruits, veggies, and low-fat milk and dairy

products), stock your home with healthy choices, limit foods containing added sugar

(especially those with little or no nutritional value), and encourage kids to be active every

day.

Above all, be a good role model. Kids will see your wholesome habits and learn to apply

them to leading a healthy lifestyle throughout childhood and into adulthood.
