Carbohydrate-rich foods are the primary source of energy for all body functions. Your body breaks down carbohydrates, or carbs, into fuel for use by your cells and muscles - that’s why eating a moderate amount of carbohydrates is necessary for most people. There are two types of carbs - sugars and starches. Sugars are simple carbohydrates that can be easily digested by your body and include foods like cake, soda, candy, jellies and fruits. Starches are complex carbohydrates that take longer to be digested and include foods such as breads, grains, pasta, tortillas, noodles, fruits and vegetables.

Many carbohydrate-rich foods are loaded with other nutrients. Fruits and vegetables are not only great carbohydrate sources, they’re also excellent suppliers of vitamins A and C and many other vitamins and minerals. Most dairy products are also great sources of carbohydrates.

Some foods rich in carbohydrates have fewer nutrients. Some foods rich in carbohydrates have fewer nutrients. Foods made from sugar (white, brown, powdered and raw) as well as corn syrup, honey and molasses are simple carbohydrates that provide little to the diet except extra calories, and too many extra calories in the diet can lead to excess body fat. Use the top layer of the Food Guide Pyramid as your guide, and limit your consumption of sugary foods - even if they do contain carbohydrates.

Quality Carbohydrate Choices
Do most of the carbs in your diet come from cookies, cakes and sugary foods? You don’t necessarily need to cut back on the number of carbohydrates you eat, but you should try to eat foods that provide your body with more nutrients and less fat and sugar. Here are a few tips for making better carbohydrate choices:

  • If you eat white bread, switch to bread made with stone ground whole-wheat flour. You can use it for sandwiches or French toast or you can grind it into breadcrumbs.
  • If you like to snack on crackers that are high in fat and sodium, switch to whole-wheat crackers. For example, Triscuits are made with whole wheat, and come in reduced-fat and low-sodium varieties.
  • Drinking milk is a great way to load up on quality carbs, but whole milk has a high fat content. Choose 1%, skim or skim milk fortified with calcium instead. Begin weaning yourself off whole milk by using skim for cooking and baking first before using it on cereal.
  • Learn how to use sugar and oil replacements in your cooking. Instead of oil, use applesauce or pureed prunes in muffins and cakes. Instead of sugar, Splenda and stevia are sweet-tasting replacers that can be used to prepare your food and drinks.Focus on Fiber
    Fiber is an important kind of carbohydrate that comes only from plant-based foods such as fruits, vegetables and grains.

    The two types of fiber are soluble and non-soluble. Soluble fiber helps control blood sugar and may also lower cholesterol. Non-soluble fiber doesn’t appear to lower blood sugar or cholesterol but may help reduce the risk of colon cancer. It also helps maintain bowel function.

    When choosing packaged breads, grains and cereals, use food labels to determine how much fiber a food contains. The fiber content of manufactured foods is listed on the Nutrition Facts label.

    Adults need between 20 and 35 grams of fiber every day, according to the American Dietetic Association (ADA). The organization reports that Americans currently are only eating between 12 and 17 grams a day.

    Good sources of soluble fiber include:

    • Oat bran (although many commercial oat bran muffins and waffles actually have little fiber)
    • Oatmeal
    • Beans and legumes
    • Peas
    • Carrots
    • Sweet potatoes
    • Rice bran
    • Barley
    • Citrus fruits
    • Strawberries
    • BananasGood sources of non-soluble fiber include:

      • Whole-wheat breads
      • Wheat cereal
      • Wheat bran
      • Rice (except for white rice)
      • Barley
      • Cabbage
      • Beets
      • Brussels sprouts
      • Turnips
      • Cauliflower
      • Fruits and vegetables with skin

      Carbohydrate Counting for People With Diabetes
      The three main nutrients–protein, carbohydrate and fat–affect blood sugar differently. Because carbohydrates contain both sugar and starch, they have the biggest impact on blood sugar. All of the carbohydrate you eat gets changed into blood glucose within five minutes to three hours after the food is eaten. For people with diabetes, knowing carbohydrates’ effect on blood sugar is important for good health.

      How much carbohydrate you eat (whether it’s sugar or starch) will determine your blood sugar level after a meal or a snack, so keeping track of your carbohydrate intake is important. Many people with diabetes have maintained good blood sugar control with a technique called carbohydrate counting. Carbohydrate counting not only contributes to better blood sugar control, it also provides more variety in food choices.

      There are two ways to count carbs: the simple way and the more advanced method. With the simple method, you work with a certified diabetes educator/registered dietitian to figure out how many grams of carbohydrate to eat at your meals and snacks. For example, if your nutritionist estimates that you need 75 grams of carbohydrates for breakfast each day you have the information you need to vary your food choices. A breakfast of cereal, milk, yogurt and blueberries will add up to 72 grams. But you might choose a breakfast of bagel, low-sugar jelly and non-fat milk for a total of 78 grams.

      The advanced method of carbohydrate counting involves matching your insulin dose to the amount of carbohydrate you eat. You will need to work with professional diabetes educators to determine your ratio of carbohydrate to insulin. In both types of carbohydrate counting, however, knowing serving sizes and reading food labels are both necessary in order to count carbohydrates.

Protein

Along with carbohydrates and fat, your body needs protein, a nutrient made up of essential and nonessential amino acids, for good health. Your body manufactures 13 nonessential amino acids, which aren’t available from food. For the body to process protein properly, the foods that you eat must contain the nine essential amino acids that are available only from dietary sources.Protein helps to maintain and replace the tissues in your body, and it’s found in almost every living cell and fluid. Your muscles, organs and many of your hormones are made up of protein, and it is also used in the manufacture of hemoglobin, the red blood cells that carry oxygen to your body. Protein is also used to manufacture antibodies that fight infection and disease and is integral to your body’s blood clotting ability. Both children and adults need plenty of protein to grow and develop.

Good Sources of Protein
Good low- or nonfat sources of protein include:

  • Beef, poultry, pork and lamb
  • Fish and shellfish
  • Dairy products, including cottage cheese, cheese, yogurt and milk
  • Eggs, egg whites or egg substitutes
  • Dry beans, peas, oats and legumes
  • Tofu and soy products
  • Nuts and seeds

Proteins are considered either complete proteins (which supply enough essential amino acids) or incomplete proteins (which lack adequate essential amino acids). Meat, eggs and dairy products are considered complete proteins, but vegetables, beans and other plant products are considered incomplete proteins. However, some incomplete proteins can be combined to create a complete protein - rice and beans, peanut butter and jelly, and corn and beans are examples of complete-protein meals.The Role of Protein in Special Diets
Although many good sources of protein are found in meat or animal products, vegetarians can still consume adequate amounts of protein. Vegetarians who eat dairy products and eggs can still choose from a variety of plant and animal protein sources. Vegans who eat only plant sources of food can still rely on tofu, soy products, oats, beans, lentils and peanut butter for protein.

People who eat too much protein may be at risk for high cholesterol or gout, a joint disorder. High-protein diets, such as the Atkins Diet and Protein Power, have also been implicated in kidney problems because of the extra effort the body must expend to process large amounts of protein. High-protein diets may also be high in fat and may lead to heart disease, according to the American Heart Association.

If you are concerned that you aren’t getting enough protein in your diet, consult your physician or a registered dietitian for dietary help.

Sugar

Sugar is a simple carbohydrate. There are two types of sugars - monosaccharides, which include glucose, fructose and galactose, are made of one sugar molecule, and disaccharides are made of two sugar molecules linked together. Disaccharides are formed when monosaccharides combine - for example, when glucose and fructose are combined, they form sucrose, also known as table sugar. Other disaccharides include maltose, dextrose and lactose. When many sugar molecules are linked together, they form a complex carbohydrate, also known as a starch.

Sugar provides the sweet flavor to foods to which it has been added, and it may also act as a preservative and flavor enhancer. Sugar is used in a variety of foods, including cookies, cakes, pickles, ice cream, alcohol and jams and jellies. Types of sugar include raw sugar, brown sugar, honey, molasses, maple sugar and corn syrup.

Sugar, which provides 16 calories per teaspoon, provides no vitamins and minerals, so it’s a good idea to use it in moderation. Overconsumption of sugar, like other carbohydrates, has been linked to the development of cavities. However, sugar consumption has not been linked to hyperactivity in children. A high intake of sugar does not cause diabetes, but if a person is diagnosed with diabetes the amount of simple sugar eaten daily often needs to be reduced.

Artificial Sweeteners
Two types of sweeteners—sugar alcohols and no-calorie sweeteners—are used to replace sugars in foods. It’s not necessary to use artificial sweeteners to eat less sugar because foods taste just fine made with less sugar. Still, artificially sweetened beverages, yogurt and desserts are a popular alternative to sugary treats.

No-calorie sweeteners currently used in foods include saccharin, aspartame and acesulfame-K. Saccharin is about 300 times sweeter than table sugar (sucrose). It’s used in several brands of table-top sweeteners, in canned foods and in low-calorie soft drinks.

Aspartame is 160 to 220 times sweeter than table sugar. Aspartame loses flavor in foods when heated. Although aspartame contains 4 calories per gram, the amount used is minute, so aspartame generally adds less than 1 calorie to a product per serving. Products that may contain aspartame include low-calorie beverages, sugar-free gelatins, yogurt, puddings, frozen desserts and cereals, as well as table-top sweeteners. Table-top sweeteners may contain an ingredient used as a filler that provides some calories. People with the condition phenylketonuria should not consume aspartame because their bodies are unable to metabolize it.

Acesulfame-K is 200 times sweeter than sugar. This newest of artificial sweeteners is being used in dry mixes for beverages, gelatin desserts, and puddings.

Artificial sweeteners must be approved by the Food and Drug Administration (FDA) for use in foods or as a table-top sweetener before they can be used by food processors or marketed for sale. Ingredient labels list any artificial sweeteners in a product.

Using Less Sugar and Sweeteners
Here are some tips for reducing sugar in your diet to make room for more nutritious foods:

  • Read ingredient labels. If sugar is listed as the first, second or third ingredient, the product probably contains a large amount of sugar as a sweetener. Identify all the sugars in a product (sucrose, honey, glucose, molasses, dextrose, corn sweetener, fructose, high-fructose corn syrup, lactose, maltose, sorghum syrup, mannitol, fruit juice concentrate, sorbitol). Select items lower in added sugars when possible.
  • Buy fresh fruits or fruits packed in water, juice, or light syrup rather than those in heavy syrup.
  • Buy fewer foods that are high in sugars such as soft drinks, fruit-flavored punches and sweet desserts. Be aware that some low-fat desserts may be very high in sugar.
  • Add less sugar to coffee, tea, cereal or fruit. Get used to half as much, then see if you can cut back even more.
  • Use less sugar in the foods you prepare at home. Try new recipes or adjust your own. Start by reducing sugars gradually until you’ve decreased them by one third or more.
  • As you reduce the sugar in your baked goods, try adding spices like cinnamon, cardamom, coriander, nutmeg, ginger and mace to enhance the sweet flavor of foods. Spiced foods will taste sweeter if warmed.

Here’s a guide for baking with less sugar:

For every cup of flour, use only:
Cakes and cookies 1/2 cup sugar
Muffins and quick breads 1 tablespoon sugar
Yeast breads 1 teaspoon sugar

Don’t worry - sugar isn’t your enemy. But reducing your sugar intake will help you cut calories and will allow you more room for more nutritious foods.
