Chapter 1- Nutrition: Food for Health Flashcards
The study of nutrients, their composition, how the body uses them (metabolism), and how these nutrients support optimal health.
Nutrition Science
Substances found in foods that are required for the maintenance of health and proper body function.
Nutrients
Building physical components of cells, bones, etc.
Structural Function of Nutrients
Maintaining the proper balance of hormones, temperature, chemical reactions, etc.
Regulatory Function of Nutrients
Providing fuel for cells to perform work.
Energy Function of Nutrients
Nutrients our body cannot make in adequate amounts, so we must get them from food. Essential in a diet, not essential to our health. All nutrients, essential or non-essential, are necessary for our health.
Essential Nutrients
A type of non-nutrient; chemicals made by plants; seem to have health-promoting properties.
Phytochemical
The animal equivalent of phytochemicals in plants.
Zoochemical
Does not contain carbon in their structure (water, minerals)
Inorganic (Chemically)
Contains carbon in their structure (carbs, fats, protein, vitamins)
Organic (Chemically)
What calories measure.
Energy
In body in larger amounts (ex. carbs, proteins, fats, water)
Macronutrient
In body in small amounts (ex. vitamins, minerals)
Micronutrient
A food that high in this may be (as a ratio) high in nutrients but low in calories. The density of a given nutrient per kcal in a food.
Nutrient Density
The study of the interaction between
genetic susceptibility and a specific lifestyle factor (diet, for example).
