2. What are Carbohydrates?
“Good” v. “Bad” Carbs
What are the types of Carbohydrates?
Dietary Fiber: How Much You Need.
Tips for Adding More Fiber
Tips for Avoiding Added Sugar
How Many Carbohydrates, Do I Need
Daily?
3. Definition:
a biological compound
containing carbon, hydrogen,
and oxygen that is an
important source of food and
energy
Your body uses carbohydrates
to make glucose which is fuel
that gives your body energy.
Glucose can be used
immediately or stored.
Healthier foods high in
carbohydrates are ones higher
in dietary fiber without added
sugar.
Carbohydrates can be found in
the following:
Fruits
Vegetables
Breads, cereals, and other grains
Milk & milk products
Foods containing added sugar
4. “Good” Carbohydrates have
more fiber and complex
carbohydrates.
Guidelines recommend
choosing fiber-rich
carbohydrate choices.
Fiber-rich foods include:
fruits, vegetables, & whole grain
breads & pastas.
“Bad” Carbohydrates are
referring to foods with refined
carbohydrates.
Refined Carbohydrates are
items that are made from white
flour or added sugar.
Examples: white bread, cakes, &
cookies
5. Complex Carbohydrates:
Starch & dietary fiber
Starch is in certain vegetables like potatoes, dry beans, cereals, and
corn.
Fiber is in vegetables, fruits, & whole grain foods.
There are two different types of fiber -- soluble and insoluble. Both are
important for health, digestion, and preventing diseases.
Simple Carbohydrates:
Can be found naturally or as added sugars
Added sugars have fewer nutrients than foods with naturally-
occurring sugars
Examples of ingredients as added sugar: brown sugar, corn sweetener,
corn syrup, dextrose, fructose, fruit juice concentrates, glucose, high
fructose corn syrup, honey.
6. It is recommended that you get 14 grams of dietary
fiber for every 1,000 calories that you consume each
day.
If you need 2,000 calories each day, you should try to
consume 28 grams of dietary fiber.
To find out how many calories you need each day visit
mypyramid.gov and enter your age, sex, height,
weight, and activity level in the My Pyramid Plan Tool.
7. Choose whole fruits
Try to eat two
vegetables with your
evening meal.
Keep a bowl of
veggies already
washed.
Choose whole grain
foods more often.
Make a meal around
dried beans or peas
instead of meat.
Start your day with a
whole grain breakfast
cereal.
8. Choose water instead of sugar-sweetened
sodas.
Choose 4 fluid oz of 100% fruit juice rather than
a fruit drink.
Have a piece of fruit for dessert and skip
desserts with added sugar.
Choose breakfast cereals that contain no or less
added sugar.
9. High-Fructose corn syrup is
a popular ingredient in sodas
and flavored drinks.
High-Fructose corn syrup is
chemically similar to table
sugar.
Research has shown that
large amounts of any type of
added sugar is linked to
health problems as weight
gain, dental cavities, poor
nutrition, and increased
triglyceride levels.
There is insufficient evidence
to say that high-fructose corn
syrup is less healthy than
other types of added
sweeteners.
American Heart Association
recommends that women
should consume no more
than 100 calories a day from
added sugar from any
source, and men should
consume no more than 150
calories a day from added
sugar.
10. Coca Cola 12 oz (355 ml)
Can Sugars, total: 39g
Calories, total: 140 Calories
from sugar: 140
20 oz (590 ml) Bottle
Sugars, total: 65g Calories,
total: 240 Calories from
sugar: 240
1 Liter (34 oz) Bottle Sugars,
total: 108g Calories, total: 400
Calories from sugar: 400
11. 1 pound of sugar equals approximately 3500 calories.
If you drink 2, 12 oz cans of regular soda a day that is
about 280 calories.
280 calories x 7 days a week = 1960 calories/week
Two weeks = 3920 calories
You could lose over a pound in 2 weeks just by cutting out
your consumption of regular soda!
12. Follow a meal plan that gives you 45%-65% of the
calories you consume as carbohydrates.
My Pyramid.gov or DASH
A diet plan that is based on no carbohydrates is
not the healthy approach to weight loss.
Choose more complex carbohydrates and avoid
food items with added sugar.
13. Now that you’ve started….
Don’t Stop!
Make physical activity a lifetime
habit
If you stop exercising you’ll rapidly
lose the beneficial effects.
Maintaining good cardiovascular
fitness is an ongoing process.
14. 4 egg whites, slightly beaten
16 ounce can pumpkin (or the meat from 1-lb pumpkin)
1/2 cup brown sugar
2 Tbsp molasses
1/2 tsp salt
1/2 tsp cinnamon
1/2 tsp pumpkin pie spice
12 oz can evaporated skim (fat free) milk
9" unbaked pie shell
Directions:
Preheat oven to 425 F. Combine ingredients in above order. Mix well. Pour into pie
shell (or into an au gratin dish for a fat-free dessert). Bake for 15 minutes at 425F. Then
reduce temperature to 350F, and bake for 45 more minutes. Makes 8 serving. Each
piece of pumpkin pie has 240 Cal, 7 g fat, 3 g saturated fat, and 7 mg cholesterol.
Without the crust, each piece would have 130 Cal, 0 fat, 0 saturated fat, and 2 mg
cholesterol. For a low sugar version, use Splenda™ instead of brown sugar, and
increase molasses to 3 tablespoons.

Editor's Notes
Some diet books use “bad” carbs to talk about foods with refined carbohydrates. Refined carbohydrates meaning they are made from white flour and added sugars. Example of bad carbs include white bread & pasta, cookies, and cakes.
Foods higher in carbohydrates such as sodas and candies contain added sugar. These carbs add extra calories but not many nutrients into your diet.
“Good” carbs is used to describe foods that have more fiber and complex carbohydrates. Complex carbohydrates are carbohydrates that take longer to break down into glucose. The Dietary Guidelines for Americans 2005 recommend choosing fiber-rich carbohydrate choices from the vegetable, fruit, and grain groups and avoid added sugars.
It is also recommended that at least half of your daily grain choices are whole grains.
Complex Carbs:
Starch and dietary fiber are the two types of complex carbohydrates. Starch must be broken down through digestion before your body can use it as glucose. This uses more energy then digesting simple carbohydrates.
Starch & dietary fiber can be found in quite a few foods such as breads, cereals, and vegetables.
Soluble fiber attracts water and turns to gel during digestion. This slows digestion. Soluble fiber is found in oat bran, barley, nuts, seeds, beans, lentils, peas, and some fruits and vegetables. Soluble fiber may help lower cholesterol, which can help prevent heart disease.
Insoluble fiber is found in foods such as wheat bran, vegetables, and whole grains. It adds bulk to the stool and appears to help food pass more quickly through the stomach and intestines.
At first you may find it challenging to eat all of your recommended daily fiber grams. Just take it slowly and try to chose higher-fiber foods more often. Gradually you will be eating more fiber!
Choose whole fruits more often than fruit juice. Fresh, frozen, or canned just make sure to go for the frozen & canned with no added sugar.
Try to eat two vegetables with your evening meal.
Keep a bowl of veggies already washed and prepared in your refrigerator. Keep the veggies in plan sight of your fridge. Don’t put them in the bottom drawer where they can be easily forgotten to rot.
Chose whole grain foods such as brown rice, buckwheat, wild rice, popcorn (without added fat & salt), quinoa, whole oats & oatmeal, & whole wheat.
Make a meal around dried beans and peas.
Start your day with a whole grain breakfast cereal. You can add fruit for even more fiber and added sweetness with no added sugar. You can add more than just bananas. Try peaches, strawberries, and even blueberries.
High-fructose corn syrup, sometimes called corn sugar, has become a popular ingredient in sodas and fruit-flavored drinks. In fact, high-fructose corn syrup is the most common added sweetener in processed foods and beverages. Given how high-fructose corn syrup is everywhere, some people are concerned about possible adverse health effects.
Research studies have yielded mixed results about the possible adverse effects of consuming high-fructose corn syrup. Although high-fructose corn syrup is chemically similar to table sugar, concerns have been raised because of how high-fructose corn syrup is processed. Some believe that your body reacts differently to high-fructose corn syrup than it does to other types of sugar. But research about high-fructose corn syrup is evolving.
Some research studies have linked consumption of large amounts of any type of added sugar — not just high-fructose corn syrup — to such health problems as weight gain, dental cavities, poor nutrition, and increased triglyceride levels, which can boost your heart attack risk. But there is insufficient evidence to say that high-fructose corn syrup is less healthy than are other types of added sweeteners.
Recommendations from the American Heart Association — not a part of official U.S. dietary guidelines — say that most American women should consume no more than 100 calories a day from added sugar from any source, and that most American men should consume no more than 150 calories a day from added sugar, and that even less is better. That's about 6 teaspoons of added sugar for women and 9 for men.
One 12 oz can of coke has 140 calories & 39 grams of sugar.
One 20 oz bottle of coke has 240 calories & 65 grams of sugar
A one liter bottle of coke has 400 calories & 108 grams of sugar.
Your best approach to healthy eating is to follow a meal plan that gives you 45%-65% of the calories you consume as carbohydrates.
MyPyramid and DASH eating plans are both examples of meal plans that give you the calories that you need and the right amount of carbohydrates. MyPyramid.gov lets you enter your age, sex, height, weight, and activity level to get a meal plan specific to your caloric needs.
DASH Eating Plan website provides a healthy eating plan with menu examples and recipes to get you started.
Carbohydrates are an important aspect of your nutrition. Your body uses carbohydrates to fuel your brain and nervous system. A diet based on no carbohydrates can be unhealthy and is unrealistic to maintain. The healthiest diets have the proper amount of carbohydrates and focus on more complex carbohydrates than simple carbohydrates.
Now that you have started… Don’t stop! An active lifestyle is not something to develop for a few days, weeks, or months and then forget. Make physical activity a lifetime habit.
If you find it hard to stick to your program ask yourself these questions,
Am I doing activities I really enjoy?
Did I seek out friends and family members who can support my efforts?
Your goal should be personal fitness. You have an individual system with unique needs and capacities. Develop it to your potential. Don’t compare yourself to a friend or neighbor.
