21-31% in women1. Moving below or above can be dangerous to one’s health. One of the most often discussed national topics in the media is the problems of obesity in America. Obesity can be measured by a formula called body mass index that uses an individuals mass in kilograms and height in meters or by a nomogram, seen below.
Calculated values can be compared to the following chart to determine whether a person’s body mass is at a healthy level. In this activity, you will calculate your own BMI, compare it (anonusemly) it to other members of the class and evaluate some of the scientific evidence for the threats of excessive consumption of trans fats and saturated fatty acids. Objectives
● Application: Scientific evidence for health risks of trans fats and saturated fatty acids.
● Application: Evaluation of evidence and the methods used to obtain the evidence for health claims made about lipids.
● Skill: Determination of body mass index by calculation or use of nomogram.

1. Open and use
Google Scholar
; Google Scholar is a way to search for primary literature source.
2. Find a primary literature source that examines the effect of either trans fats or saturated fatty acids on coronary heart disease (CHD). Your source needs to be a published study from a scientific journal.
