29. Imagine you are working with a team of researchers to conduct a national survey of nutrition and health. You will travel around the country in a mobile lab (i.e., a van equipped with computers and research instruments) and interview many people about their health habits. You will also take some anthropometric measurements of the study participants to evaluate their weight status and health risks. Of all the weight status and body composition assessment techniques you've learned about in this Nutrition Lab, which technique(s) would you choose to use in this national survey? Explain your rationale. You might consider factors such as the size and expense of the equipment, the ease with which the technique can be used by the research team, or how well the research subjects will tolerate the measurements.

Nutrition and diet

We are involved in several daily activities. These actions need a significant quantity of energy. The food we eat provides this energy. Food is necessary for development, repair, and other living activities since it supplies energy. All of these are part of the living practice known as nutrition. Nutrition is the study of nutrients in food, how the body uses them, and the relationship between diet, health, and disease. Nutritionists employ concepts from molecular biology, biochemistry, and genetics to understand how nutrients affect the human body. Nutrition also looks at how people can use their diet to reduce their risk of disease, as well as what happens when they ingest too much or too little of a nutrient and how allergies emerge.
