Nutrition
• Is it true…You Are What You Eat?
• What factors are important when considering good nutrition?
• How important is good nutrition to you?
• How does food get to your plate?

BMI – Body Mass Index• Measure of Body Fat based on
Height and Weight
• Calculating BMI:(Weight in lbs/Height in inches2) x 703
• Categories:– Underweight = Less than 18.5– Normal Weight = 18.5-24.9– Overweight = 25-29.9– Obesity = BMI of 30 or greater

Limitations of BMI
• Can overestimate for an athlete with a muscular build
• Can underestimate for an older person who has lost muscle
• Greater Accuracy can come from using multiple measures– EX: Waist circumference along with
BMI / BodPod / Underwater Measurements

Calories
• A measure of heat or energy.
• Required for your body to function.
• Calories come from:• Fat – 9 calories• Carbohydrates – 4 calories• Protein – 4 calories

Calorie IntakeBasic Calorie Intake will include the
base number of calories for your body to accomplish basic needs (like breathing, heart rate, etc.)
Increasing Calorie Intake can lead to weight gain
Decreasing Calorie Intake can lead to weight loss
Weight loss = Greater Calorie Expenditure vs. Calorie Intake

Macronutrients
• Carbohydrates
• Protein
• Fats
• Fiber
![Page 8: Chemistry of Food Introduction "Protein, Fiber, and Nutrion" Video.](https://reader036.fdocuments.net/reader036/viewer/2022081821/56649e575503460f94b5047e/html5/thumbnails/8.jpg)
Proteins
• Purpose of Proteins is to help build and maintain muscle, organs, skin and blood
• Helps with metabolism
• Helps the immune system
• 10-35% of the body should be fueled by protein
![Page 9: Chemistry of Food Introduction "Protein, Fiber, and Nutrion" Video.](https://reader036.fdocuments.net/reader036/viewer/2022081821/56649e575503460f94b5047e/html5/thumbnails/9.jpg)
Fats• Provides the most energy as compared to
proteins and carbs• Essential for health of the body – cushions
organs, surrounds all cell membranes, and insulates.
• Unsaturated Fats – liquid at room temp.• Saturated Fats – solid at room temp.• Omega 3 Fatty Acids – “good” fat…can get
from some fish and nuts…helps the brain• 20-35% of energy in a day should come from
fats

Carbohydrates
• The main source of energy for the body
• Can be stored as Glycogen for use at a later time
• Available in grains, veggies, fruits, nuts, and milk
• 45-65% of all energy should come from carbohydrates in a day
![Page 11: Chemistry of Food Introduction "Protein, Fiber, and Nutrion" Video.](https://reader036.fdocuments.net/reader036/viewer/2022081821/56649e575503460f94b5047e/html5/thumbnails/11.jpg)
Fiber
• Helps the body feel full faster (provides bulk)
• Helps the body stay regular – and keeps the Digestive Tract healthy
• Need 20-40 grams per day

Vitamins and Minerals• Vitamin A• Vitamin C• Vitamin D• Vitamin E• Vitamin K• Thiamin• Riboflavin• Niacin• Vitamin B6• Vitamin B12• Pantothenic Acid• Biotin• Choline• Folate
• Calcium• Chromium• Copper• Fluoride• Iodine• Iron• Magnesium• Manganese• Molybdemnum• Phosphorous• Selenium• Zinc• Potassium• Sodium• Chloride

Controlling Food Intake• We will examine your individual food /
calorie intake with your completed 7 day food diary.
• This will allow you to consider possible changes to your current diet.
• Go to http://www.mypyramid.gov/ for a personal food pyramid and also to look up food items for you food diary

Food Pyramid• New Guidelines - informational video

Weight as an Indicator of Health
• Too much weight can lead to Type II Diabetes, Heart Problems, High Blood Pressure, Stroke, Sleep Apnea, Depression, Other bone disorders, infertility
• Too little weight can lead to infertility, anemia, osteoporosis, immune system deficiencies
