ADDED SUGARS: TOXIC WAIST?

Presented by Brandon Lee, B.S.

WHAT DOES HEALTHY MEAN?

• Health is defined by the World Health Organization as a state of

complete physical, mental, and social well-being, not merely the

absence of disease.

SUGAR= CARBOHYDRATESCARBOHYDRATES = SUGAR

• Simple carbohydrates- a monosaccharide or disaccharide.

• Monosaccharide-The simplest of carbohydrates; consists of one sugar molecule

• Glucose

• Fructose

• Galactose

• Disaccharide- A carbohydrate compound consisting of two sugar

molecules joined together

• Lactose

• Maltose

• Sucrose

MONOSACCHARIDES

• Glucose- the most abundant sugar molecule, found in combination

with other sugars.

• The preferred source of energy for the brain and an important

source of energy for cells.

• Fructose- the sweetest natural sugar; is found in fruits and vegetables.

Also called fruit sugar.

• In many processed foods, it is in the form of high fructose corn

syrup.

• High fructose corn syrup is made from corn and is found in soft

drinks, candies, jellies and desserts.

MONOSACCHARIDES CONT.

• Galactose- a sugar that joins with glucose to create lactose.

• This sugar is not found in food alone.

DISACCHARIDES

• Lactose- consists of one glucose molecule and one galactose molecule,

also called milk sugar.

• Found in milk, including human breast milk.

• Maltose- consists of two molecules of glucose.

• Seldom found in food alone but results as a by-product of digestion.

Also called malt sugar.

• Maltose is also the sugar that is fermented during production of beer

and liquor products.

DISACCHARIDES CONT.

• Sucrose- composed of one glucose molecule and one fructose

molecule.

• It is sweeter than lactose or maltose.

• Found in honey, maple syrup, fruits and vegetables.

• Sucrose is also the base sugar for table sugar, brown sugar and

powdered sugar.

COMPLEX CARBOHYDRATES

• Defined as a nutrient compound consisting of long chains of glucose

molecules.

• Starch

• Glycogen

• Fiber

STARCH

• Defined as polysaccharide stored in plants; the storage form of glucose

in plants.

• Food sources include grains (wheat, rice, barley), legumes (peas and

beans), and tubers (potatoes and yams).

• Starch is broken down to monosaccharides during digestion.

FIBER & GLYCOGEN

• Fiber is defined as the nondigestible carbohydrate parts of plants that

form the support structures of leaves, stems, and seeds.

• Two types: Insoluble and soluble

• Found in citrus fruits, berries, wheat and brown rice.

______________________________________________________

• Glycogen is defined as a polysaccharide stored in animals; the storage

form of glucose in animals.

• Stored in the liver and muscle.

• Seldom found in food items.

WHAT IS ADDED SUGAR?

• Added sugars can defined as any sugar that is not naturally occurring in

the food and has been added manually.

• The most common source of added sugars in the U.S. diet is

soda and soft drinks; Americans drink an average of 40

gallons per person per year.

• Those who drink the average amount, consume more than

16,420gms of sugar (about 267 cups) every year.

• Other common sources of added sugars include cookies, cakes, pies,

fruit drinks, fruit punches and candy. In addition, non-dessert food

items also have excess sugar such as peanut butter, yogurt, and even

salad dressing.

SUGAR MATH

Divide the total grams of added sugar by 4 to get

teaspoons.

Multiple the total grams of added sugar by 4 to get

calories.

DIETARY GUIDELINES ADVISORY COMMITTEE (DGAC)

• DGAC express that there is strong evidence that diets high in added

sugars are associated with overweight, obesity and type 2 diabetes.

• DGAC express that there is moderate evidence that diets high

added sugars are associated with dental caries, hypertension, stoke and

cardiovascular disease.

• The upper limit (UL) set by DGAC is 10% of energy (calories) to come

from added sugars in the diet.

Note: Insufficient evidence exists to asses the effect of added sugars and

low calorie sweeteners contained in foods and beverages on individuals

from diverse populations who have high risk for adverse health

outcomes.

EVIDENCE-BASED RESEARCH: OBESITY

• In three studies, scientists randomly

assigned people to consume either sugary

beverages (made with sugar or high

fructose corn syrup) versus sugary

beverages (usually made with aspartame).

• The study lasted from three-ten weeks.

• Result: Only those who consumed sugar

or high-fructose corn syrup gained weight.

EVIDENCE-BASED RESEARCH: OBESITY CONT.

Calories from fructose are more likely than other calories to add fat

around the waist.

• In one study, researchers gave 32 overweight or obese middle aged

men and women 25% of their calories from beverages sweetened with

either fructose or glucose for the course of ten weeks.

• Results: Both groups gained an average of about three pounds.

However, their was an increase in visceral fat in people fed fructose.

• Visceral fat has a positive connection with a higher risk of heart

disease and diabetes than subcutaneous fat.

EVIDENCE-BASED RESEARCH: OBESITY CONT.

• Researchers at the University of Minnesota studied about 800 men and

women.

• Result: Those who drank the most sugar sweetened beverages had

more visceral fat and larger waists.

EVIDENCE-BASED RESEARCH: DIABETES

The fructose in added sugars appears to increase liver, muscle and

visceral fat. Excess fat anywhere in the body increases the risk of insulin

resistance and diabetes. However, a fatty liver and visceral fat may

increase a person’s risk the most.

• High intake of added sugars in the diet can lead to increased risk of

developing metabolic syndrome, which can lead to type 2 diabetes or

heart disease.

EVIDENCE-BASED RESEARCH: LIPID PROFILE

• In 2010, researchers at Emory University that took a sample of 6,000

adults. Those who drank more sugar from drinks and foods had lower

HDL (“good”) cholesterol and higher triglyceride levels in their blood.

• When there is more sugar in the body than the liver can process, it

converts the sugar to fat. Some of the fat goes into the bloodstream,

hence high triglyceride levels.

EVIDENCE-BASED RESEARCH: TOOTH DECAY

• Simple carbohydrates play a role in dental problems

• The bacteria that cause tooth decay thrive on simple carbohydrates.

• These bacteria produce acids that eat away at tooth enamel and can

eventually cause cavities and gum disease.

IS HIGH-FRUCTOSE CORN SYRUP WORSE THAN TABLE SUGAR???

• High fructose corn syrup= 55% fructose and 45% glucose

• Sucrose= 50% fructose and 50% glucose

• Overall, added sugars, whether they come from sucrose, high fructose corn syrup or fruit juice concentrate all have equal adverse effects metabolically.

• One study reported that people who were given 24 ounces of Dr. Pepper sweetened with high fructose corn syrup had higher blood sugar levels over the next six hours than those who got sucrose-sweetened Dr. Pepper. Other studies have found no difference.

• The sugars in juices are natural but is still are large contributor. Evidence shows that there is an increased risk of developing type 2 diabetes with consumption of fruit juices but not with whole fruit. Fiber in fruit provide protective benefits from risk of diabetes.

EMPTY CALORIES

• In a nationally representative

survey of 16,000 people, about 78%

of women and 67% of men ate too

much added sugar.

Not so fun fact: A slice of Starbucks

Reduced Fat Cinnamon Swirl Coffee

Cake has 10 teaspoons of added

sugars.

SPORTS DRINKS

• When inactive people drink sports beverages, a common consequence

is inappropriate weight gain.

• Drinking a 12fl. Oz (1.5 cups) of Gatorade adds 90 calories to a

person’s daily energy intake.

• When looking for a good sports drink make sure it has 50-70% of

calories from carbohydrate (13-18g of carbohydrate per 8 oz, or 240

mL).

• Alternative options: Low fat or skim milk. Milk will have electrolytes

that enhance fluid retention and restore normal fluid balance. All at a

lower cost ($) and with significantly less added sugars.

RECOMMENDATIONS

• Limit sugar intake to 10% or less of total energy intake each day.

• Consume a maximum of 100 calories (6 ½ teaspoons) a day of added

sugar for women and 150 calories (9 ½ teaspoons) a day for men.

• Limit fruit juices to no more than 1 cup a day.

• Drink/eat milk, fruit and plain yogurt without worry about sugar.

• Limit intake of high fructose corn syrup, cane or beet sugar, evaporated

can juice, brown rice syrup, agave syrup and honey.

THE MANY NAMES OF SUGAR

Barley Malt Brown Rice Syrup Brown Sugar Cane Syrup

Crystalline Fructose Dextrose Fructose High Fructose Corn

Syrup

Honey Invert Sugar Lactose Maltodextrin

Maltose Mannitol Sorbitol Xylitol

Maple Syrup Molasses Muscovado Sugar Barbados Sugar

Sucanat Sucrose Turbinado White Grape Juice

Mannitol, sorbitol and xylitol are considered sugar alcohols and do not

contribute to “total carbohydrates”.

WAYS TO REDUCE ADDED SUGAR INTAKE

• Add cinnamon and dried fruit to plain

cooked oats instead of using instant flavored

oatmeal.

• Switch from sweetened to unsweetened

applesauce.

• Eat jams and jellies with no sugar added.

• Quench your thirst with water, low-fat milk,

or beverages, like low sugar sports drinks.

WAYS TO REDUCE ADDED SUGAR INTAKE CONT.

• Sweeten low-fat plain yogurt with fresh,

frozen, or canned (in its own juice) fruit in

place of fruit-flavored yogurt.

• Trade out 100% fruit juice for fruit punch and

other fruit-flavored drinks.

• Drink plain low-fat milk instead of chocolate

milk.

• Make a homemade smoothie with frozen

fruit, low-fat milk, and yogurt in place of ice

cream.
