“A NATURAL PHYSICALDRIVE THAT PROTECTSYOU FROM STARVATION”
“A DESIRE, RATHERTHAN A NEED, TO EAT”
CARBOHYDRATES*THE BODY’S PREFERRED SOURCE OFENERGY, OR CALORIES*
CARBS CAN INCLUDE:SUGARSSTARCHESFIBER
55-65% OF YOUR CALORIES SHOULDCOME FROM CARBS
GOOD SOURCES OF COMPLEx CARBSINCLUDE VEGETABLES, PASTA, SEEDS,AND NUTS.
SUGARS, OR SIMPLE CARBS, AREPRESENT NATURALLY IN MANY FOODS, INCLUDING FRUITS, SOMEVEGGIES AND MILK
FIBER DIETARY FIBER IS ANOTHER FORM OFCOMPLEX CARBOHYDRATE
*FIBER IS THE TOUGH STRINGY PARTOF VEGETABLES, FRUITS AND GRAINS*
*FIBER HELPS MOVE WASTE THROUGHYOUR DIGESTIVE SYSTEM.* EATING ENOUGH FIBER THROUGHOUT LIFE MAYHELP YOU AVOID CANCER.
*FATSTHE NUTRIENT FAT HAS SEVERALIMPORTANT FUNCTIONS IN HEALTH
*FAT IS KNOWN BY THE SCIENTIFICNAME LIPID* LIPIDS ARE FATTY SUBSTANCES THATDO NOT DISOLVE IN WATER
THERE ARE TWO TYPES OF FATS
*SATURATED FATS- ANIMAL FATS* SUCH AS MEATS, DAIRY FOODS, PORK AND EGG YOLKS
*UNSATURATED FATS-THIS INCLUDES MOST VEGETABLE FATS….OILS*
*FATS CARRY FAT- SOLUBLEVITAMINS A D E AND K INTO YOURBLOOD.*
WITHOUT FATS OUR BODIES COULDNOT USE THESE NUTRIENTS
FATS ADD FLAVOR AND HELP TOSATISFY HUNGER. FATS SURROUND AND CUSHION YOURVITAL ORGANS
ALMOST EVERY FOOD HAS SOME FAT -ATLEAST IN VERY SMALL AMOUNTSVISABLE FATS - BUTTER, VEG. OIL,FAT LAYER ON MEAT, ACCOUNT FOR ABOUT 40% OF THE FAT IN OUR DIET.
MANY FATS ARE HIDDEN IN FOODSCHOCOLATE, SEEDS, NUTS, EGG YOLKS, ICE CREAM, SOUPS , ANDDOUGHNUTS ALL HAVE HIDDEN FATS
*CHOLESTEROL IS A FAT LIKE SUBSTANCE*
IN MANY WAYS CHOLESTEROLRESEMBLES FAT. BECAUSE THE HUMAN LIVER CAN MAKE CHOLESTEROL IT NEEDS, IT IS NOTCONSIDERED A NUTRIENT. THE BODY USES CHOLESTEROL TO PRODUCE CERTAIN HORMONES, VIT D, AND PROTECTS NERVE FIBERS
IN SOME PEOPLE THE BODY MAKES TOO MUCH CHOLESTEROL. HIGH CHLOSTEROL IS A FACTOR IN HEART AND OTHER CIRCULATORY DISEASES.
SOME PEOPLE TAKE MEDICATION TOLOWER THEIR LEVEL OF CHOLESTEROL
PEOPLE CAN ALSO LOWER THEIRCHOLESTEROL BY CUTTING OUT CERTAIN FOODS IN THEIR DIETS
*PROTEINS- ARE A VITAL PART OF EVERY BODY CELL*
MUSCLE, BONE CONNECTIVE TISSUE, TEETH, SKIN, BLOOD, AND ALL VITAL ORGANS CONTAIN PROTEIN.
YOUR BODY USES PROTEINS MAINLYFOR BUILDING AND MAINTAINING ALL BODY TISSUES.
*SOURCES OF PROTEINSMEATS, FISH, POULTRY, EGGS, MILK,CHEESE, YOGURT*
SEEDS AND NUTS ARE THE BESTSOURCE OF PLANT PROTEINS.HOWEVER, NO SINGLE PLANT PROTEIN HAS ENOUGH PROTEIN
*VITAMINS- ARE KNOW AS MICRO-NUTRIENTS* BECAUSE THEY ARE NEEDED IN SMALL AMOUNTS.
VITAMINS HELP REGULATE MANYVITAL BODY PROCESSES. THEY DONOT SUPPLY CALORIES.
TWO TYPES OF VITAMINS
*WATER-SOLUBLE -DISOLVE IN WATER VIT B AND C* *FAT-SOLUBLE - ABSORBED AND TRANSPORTED BY FAT (VIT A, D, E, AND K*
MINERALS - SUBSTANCES THAT THE BODY CANNOT MANUFACTURESOME IMPORTANT MINERALSSODIUM,CHLORINE AND POTASSIUMBANANAS AND POTATOES ARE A GOOD SOURCE OF POTASSIUM
*WATER - OUR MOST IMPORTANTNUTRIENT. ONLY OXYGEN IS MOREIMPORTANT TO LIFE.* MOST PEOPLENEED ABOUT *10 CUPS* OF WATER EVERY DAY.
