How Refined Sugars Behave in the Body Eat refined sugar (ex: candy or pop) Increase blood sugar Glucose almost immediately absorbed in bloodstream- fast increase blood sugar Glucose leaves blood and enters cells- used for fuel Rapid decrease in blood sugar triggers liver to release sugar and feelings of hunger increase (eat again) Breaks down to glucose
What happens when we drink or eat too much sugar? The sugar in soda pop not only provides a massive dose of calories, but triggers a vicious appetite cycle, said Ludwig, who wrote "Ending the Food Fight," about healthy eating for children. "It's rapidly absorbed, which raises blood sugar and in effect causes the body to panic." The body releases insulin to break down the sugar, "but the body overcompensates, and blood sugar drops below the fasting level," lower than it was in the first place. Recognizing low blood sugar, the body releases ghrelin and other hormones, inducing hunger, inducing us to eat even more, Ludwig said.

Insulin Resistance Eventually our pancreas wears out from frequent release of insulin in part due to high processed sugar diets Insulin is not produced enough or body does not respond to it properly Body cells do not respond to insulin properly, causes pancreas to release more, eventually pancreas cannot keep up and sugar builds up in blood Increases risk of type 2 diabetes & heart disease
Glycogen and Fat Storage Extra sugar not needed is first converted to glycogen- stored in liver and muscle (LIMITED AMOUNT) Once glycogen stores are full- remaining glucose is stored as fat *Dr.
Sugar Facts Amount of sugar in two pops decreases immunity- 40% reduction in killing germs – Lasts from less than 30 minutes after sugar eaten up to 5 hours Promotes cravings, obesity, diabetes, heart disease (inflammation)
How to Spot Added Sugar Dextrose Sucrose Fructose Maltose Corn syrup High fructose corn syrup Molasses Brown sugar Raw sugar Honey
Added Sugar Recommendations American Heart Association: – Limit added sugars to no more than 6-9 teaspoons/cubes per day – grams
Fruit and Vegetables (Whole Food) Natural sugar + fiber + vitamins + minerals + complex carbohydrates= steady absorption of sugar Processed Carbohydrates (sugar) Creates unstable blood sugar, mood instability, irritability, anxiety, and jitteriness ** Dr. Sears askdrsears.com
Nutrient Density High nutrient density- – Nutrient-dense foods have a high nutrient/calorie ratio. Meaning they are rich in nutrients when compared to their calorie content. (Whole real food) Low nutrient density- – Low in nutrition when compared to their calorie content. (Highly processed food) Which is more nutrient dense? – Fried chicken nuggets or baked chicken? – Fruit salad or doughnut?
THINK YOUR DRINK ACTIVITY Guess the added tsp of sugar in each drink!
4 grams sugar = 1 tsp or 1 cube of sugar
How did we get from grams of How did we get from grams of sugar to cubes of sugar?
White Milk White Milk has 12 grams of natural lactose sugars. 0 grams of added sugars
Chocolate Milk has 25 grams of total sugar - 12 grams lactose sugars added = 13 grams of added sugars 13 grams / 4 grams = 3 tsp added sugar
Soda has 39 grams sugar /4gm = 10 cubes or 10 tsp of sugar
THINK YOUR DRINK ACTIVITY 39 grams sugar / 4gm = 10 tsp of sugar 4 grams sugar = 1 tsp or 1 cube of sugar
Sugar Cubes in Soda

Artificial Sweeteners- No Sugar Added/ Sugar-free (diet sodas, ice cream, cereal, fruit juice, sports and energy drinks) Some studies show: – Makes you hungrier and crave sweets – Statistically- more diet soda in diet, more likely to become overweight – Eating unnatural substances may cause brain to perform in unnatural ways – Some report headaches and chronic fatigue Examples: – Aspartame (Equal and Nutrasweet) – Sucralose (Splenda) – Saccharin – Acesulfame K (Sweet One) Stevia- herb in South America (leaves), a step in right direction – Some forms are highly processed with sugar alcohols, Truvia/ PureVia – SWEETLEAF IS BEST BRAND
