Slide1

Carbohydrates

One of the three macro-nutrientsThe main nutrient in grain productsProvides much of the fuel that keeps the body goingSlide2

Carbohydrates

The body’s most preferred source of energy4 calories/gramLargest volume of our daily diet (60% on average)

CDC recommends 45%-65% of our calories be carbs

Form of food

Form of sugarSlide3

Carbohydrates Role

Turned into Glucose (sugar) in the bodyGlucose is the energy supply for the body’s automatic activity and for the performance of our daily tasksSlide4

Carbohydrates Role

Important to metabolismComplex carbs will increase metabolismAny unused Carbohydrates/Glucose is stored as fatSlide5

Carbohydrates = Sugar= Energy

Glucose is freed in the small intestinesHydrolysis= splitting of a compound into smaller parts by the addition of waterCarbohydrates are broken down until they yield the sugars from which they are formedSlide6

Grains –Our Main source of Carbohydrates

Parts of Grain: Bran, Endosperm, GermSlide7

The Three most common in

USWheatCornRice

(Wild Rice is not really rice, but merely a grass seed)

Other Common grains:

Oats

Rye

BarleySlide8

Whole Grain

Grains that contain germ, endosperm, and bran

Wheat

Oat

Barley

Maize

Brown Rice

Farro

Spelt

Einkorn

Kamut

Rye

Millet

Quinoa

Amaranth

Triticale

Teff

Emmer

BuckwheatSlide9

Refined Grain

Removal of Bran and GermMay involve bleachingMany nutrients are lostSlide10

Enriched Grains

Nutrients lost in Refining are put backRepresent a fraction of nutrients removedInferior to whole grainsSlide11

Fortified Grains

Replaces same nutrients as enriched foodsAlso adds more nutrients that were not naturally thereCalcium in OJIodine in table salt

Vitamin D in MilkSlide12

Food Labels & Grains

Wheat proteinGlutenGrain proteins Incomplete proteinsSlide13

Surprising Food Sources of Carbohydrates

Plant based foodsDairy productsLactose (milk sugar)Slide14

Simple Carbohydrates

SUGARS= GlucoseBasic source of energyQuick

energy

Found in Fruits

Sucrose – table sugar

Fructose – fruit sugar

Glucose – blood, grape, corn sugar

Maltose – malt or grain sugar

Lactose – milk sugarSlide15

Sources of Simple Carbohydrates

SugarFruitFruit juiceTable sugar

Honey

Soft drinks

sweetsSlide16

Simple Carbohydrates

Simple carbohydrates quick energy sourcesBut usually no other nutrients or fiberSlide17

Complex Carbohydrates

Supply energy other nutrients and fiber that the body needsThe better choice. Slide18

Complex Carbohydrates

CelluloseMajor component of plant cell wallsStarch (amylose)PlantsGlycogen

Stored form of glucose in body, animal starchSlide19

Complex Carbohydrates

Starch: Supplies the body with long, sustained energyAll starchy foods are plant foodsSeeds 70% starch

Bean and Pea family 40% starch

TubersSlide20

Sources of Complex Carbohydrates

StarchBreadCereal

Potatoes

Pasta

Rice

legumes

Fiber

Bran

Whole-grain

Raw vegetables

FruitSlide21

Dietary Fiber

Found in plant cellsTough and stringyDoes not break down completelyThe Non-digestible part of plantsSlide22

Why Fiber?

Keeps food moving efficiently through the body:preventing constipation & hemorrhoidsDecrease chances of heart disease by lowering cholesterolSlide23

Why Fiber?

Helps to control blood sugar levels Important for diabeticsHigh fiber eating is lower in calories, makes you feel fuller faster =

weight controlSlide24

How much Fiber do we need?

25 grams per day for women38 grams per day for menSlide25

High Fiber Foods

BeansWhole grainsBrown ricePopcornNutsBaked potato with skin

Berries

Bran cereal

Oatmeal

vegetablesSlide26

Choosing the Best Bread

Look for:Short ingredient listAt least 3g fiberThe word “whole” in the ingredients

Be wary of

Wheat flour: (25% wheat 75

% white

flour)

Enriched flour

Sugar gramsSlide27

Breads in Categories

“Best Breads”100% whole wheat 1st ingredient

No enriched flour

Better Breads

List whole wheat as 1

st

ingredient

May have enriched flour in the ingredients

“No

No

Breads

Bleached, enriched flour 1

st

ingredientSlide28

Unbolted???

Unbolted: means that the bran has not been removedHigher fiberBolted: means that the bran has been removedSlide29

Flour & Grain unveiled

Buckwheat (Soba) Flour: does not contain wheat or glutenOat Flour: makes for a moister whole-grain breadRye Flour: high protein and fiber, should say “unbolted”

Cornmeal: white or yellow, may be “bolted” or “unbolted” Slide30

Flour unveiled

Soy Flour: ground soybean, high in proteinArrowroot Flour: starch, root of a plant, easy to digest, main ingredient in many infant and toddler snacksRice: more starch than gluten

Spelt: cereal grain, more nutritious than wheat

Corn (maze): pasty

Kamut

: type of wheat, high proteinSlide31

Cereals

CeresRoman Goddess of AgricultureHow we get the word: CerealSlide35

Choosing the Best Cereal

Nutrients you want in your cereal: fiber, protein, folic acid, zinc, iron, B-VitaminsDon’t:

Choose based off of TV

Ignore the front of the box

Get caught up in

Vit

C and calcium advertisements

Sugar should not be near the top of the ingredient list

Do:

Read the ingredient list

Look for “whole” as the 1

st

ingredient

Avoid:

Hydrogenated oils

Dyes or artificial colors

Chemical preservativesSlide36

Ideal Cereal

1st ingredient should be “whole”…Contain at least 3 g fiber per servingCarbohydrate-to-sugar ratio should be no less than four to one (means most carbs are complex not simple)

Best would be 7 to 1Slide37

Ideal Cereal

Five and Five ruleLess than 5 grams of sugar and at least 5 grams of fiberIron, Zinc & other vitamins and minerals should be 25-40% of recommended daily allowanceFocus on the quality of the grain verses the vitamin listSlide38
Slide39
Slide40
Slide41

Choosing the Best Cracker

Look for: FiberMineralsVitaminsBe aware of the serving size

Aim for:

At least 3 grams fiber

No more than 3g fat

No more than 1 g saturate fatSlide42
Slide43
Slide44

Carbohydrate Review

Largest volume of our daily diet 45% - 65% of your calories)Example 60% Carb Intake2000 calorie a day diet2000 X 0.60 = 1200 calories from Carbohydrates per

daySlide45

How to calculate grams of Carbs you need daily

Carbohydrates provide the following amount of energy4 cal/gDetermine how many g of carbohydrates you need first

1200

cal

divided by 4

cal

=

300gSlide46

Calculating Carb calories in your foods

Example20g Total Carbohydrate20g multiplied by 4 cal = 80 calories

from CarbohydratesSlide47

Carbohydrate Tips

Short ingredient listAt least 3 g fiberThe word “whole” UnboltedCarbohydrate-to-sugar ratio should be no less than four to one No more than 1 g saturated

fatSlide48

Blood Glucose Levels

Digestion:Pancreas: Monitors the flow of glucose to the cells by secreting insulinHormone:

Insulin is a hormone and is a chemical messenger that affects a specific organ or tissue and brings forth a specific response Slide49

Blood Glucose Levels

Insulin: keeps glucose in the blood at a normal levelToo much glucose and insulin tells the liver and muscles to store it as glycogenToo little glucose and the liver and muscles release the glycogen back into the bloodSlide50

Diabetes

The body cannot regulate Blood Glucose levelsType 1: Pancreas secretes little or no insulinType 2:

Pancreas does not produce enough insulin, or the body does not use the insulin effectivelySlide51

Diabetes

Type 1 & 2: both cause HyperglycemiaLittle glucose reaches the cells, the kidneys and heart become strained trying to filter out the glucose

Cells are not getting the energy that they needSlide52

Diabetes

Type 1:Body thinks it starting and responds by breaking down proteins and

fats

Type 2:

Cells get just enough glucose, but, trying to feed the glucose-hungry cells people will overeat, leading to obesity….Slide53

Treatment

Type 1: Daily insulin injections, exercise, and a careful dietType 2: Diet and Exercise, sometimes medicationsSlide54

Diet & Exercise

½ will control the disease with just diet & exerciseDiets are individualized, but similar to any healthful eating planLimit fat, sodium, protein, simple carbsIncrease complex carbs especially the starchy ones

Eating regularly to maintain a steady blood glucose levelSlide55

Diabetes without Treatment

StrokeHeart AttackKidney Damage/FailureImpotenceNumb extremities (Neuropathy)

Loss of limbs

Loss of eye sight

Infertility

Prolonged healing

High Blood PressureSlide56

Statistics

$218 Billion to treat diabetes in the US yearly60% of amputation are in diabetics202,290 diabetics with end stage kidney disease4.2 million people with diabetes are losing their vision

68% of diabetic deaths are linked to heart disease

25.8 million

A

mericans are diagnosed

79 million have been diagnosed

Prediabetic

1.9 million new cases a yearSlide57

Hypoglycemia

Abnormally low level of blood glucoseDizzy, weak, nauseated Corrected with a prescribed diet and eating schedule
