Study Notes
Nutrition Calculations
- Body Mass Index (BMI) is a measure of weight and height, used to estimate total body mass and correlate with body fat percentage.
- Ideal body weight is the weight a person with good health and long lifespan is expected to have for a given height.
- BMI is a simpler, more acceptable measure than ideal body weight.
- WHO provides ideal weight ranges for different heights.
- BMI values help categorize people as normal (ideal), undernourished, overweight, or obese.
- BMI is calculated using weight in kg and height in meters.
- A higher BMI number indicates more body fat, while a lower number indicates less body fat.
- A healthy BMI range is generally between 18.5 and 25.
- Up to 28 is acceptable for those over 50.
- Obesity is categorized as 30-40, and morbid obesity is over 40.
- Severe malnutrition is 17.5 and lower.
Daily Calorie Needs
- Daily calorie needs depend on weight, height, gender, age, and activity level.
- Activity level is estimated by the number of minutes spent exercising daily, including walking.
Determining Servings per Food Group
- A balanced diet includes servings from each food group.
- A calculator can be used to determine the number of servings needed from each food group based on daily calorie goals.
- Calorie goals between 1000 and 9800 can be used in the calculator.
- The number of calories entered is rounded to the nearest 200.
Serving Size Examples
- Grains: 1 slice of bread, ½ cup cooked rice.
- Vegetables: Tennis ball-sized serving.
- Fruits: Tennis ball-sized serving or medium-sized piece, ½ cup juice.
- Dairy: 1 cup low-fat milk/yogurt, 2 dominoes-sized cheese pieces.
- Meat & Beans: Card deck-sized piece of lean meat, ½ cup beans.
- Vegetable oil: 1 tablespoon.
- Extra calories: Small piece of cake, ½ candy bar, 2 golf ball-sized scoops of ice cream.
Activity Factor
- Activity levels (sedentary, <30 minutes, 30-60 minutes, >60 minutes) determine activity factors (PA).
- Activity factors are used to adjust daily calorie needs.
- Separate factors exist for men and women, and boys and girls (ages 3-18).
