Nutrition Research Use your phone or a laptop to access the following: CalorieKing.com If you are unsure which measurements to use for your food, come to the front (I have examples!) Write down on your worksheet the calories, fat, carbs, and protein for your daily diet!

Health & Metabolism NUTRITION- The process of digestion and absorption of foods and the body’s use of it for growth and replacement of cells You will consume about 50 tons of food in your lifetime Unhealthy diet can lead to illness Heart Disease Cancer Type 2 Diabetes High Blood Pressure Stroke Osteoporosis

Carbohydrates Most nutritionists agree that 55 to 65% of our diet should be carbohydrates Primary source of energy – easiest food to break down and use for energy. Produced by all plant life – fruits, vegetables, grains (6-11 servings a day).

Protein It is recommended that 15 to 20% of the diet come from protein Function: vital part of every body cell – muscle, bone, blood, and organs Excess protein cannot be stored in the body Examples- meat, milk, poultry, cheese, fish, and eggs

Fats Most nutritionist agree that we should reduce fat intake to under 30% of our diet. Fats contain about 9 calories per gram (twice as many carbohydrates or protein) Function: storage form for food energy (add flavor and help satisfy hunger) Bad Fats = Trans Fats (more solid and resistant to chemical change, butter)

Food Journal Analysis Use the instructions on the back of your Food Journal to analyze your daily eating habits Make sure to pay attention to what you are supposed to be calculating! Calculators are located at the front if you need one Finished?? Make sure your Digestive Model is complete!

Exit Quiz What was your average number of daily calories? Do you think this is a good number? How close were you to the suggested percentage of macromolecules? (Protein-20%, Fat-30%, Carb-60%) Should you alter your diet in any way? What should you eat more of or less of?
