Dictionary
Key Food Nutrition Terms
Plain definitions, with how to say each word and where it comes from.
- Antioxidant
An antioxidant is a substance that prevents or slows oxidation, especially damage to cells from free radicals and other reactive oxygen species.
- Basal metabolic rate
Basal metabolic rate is the energy the body uses per unit of time just to stay alive when awake, lying at rest, fasting and in a comfortable temperature.
- Body mass index
Body mass index is a screening measure that relates body weight to height, found by dividing weight in kilograms by height in meters squared.
- Calorie
A calorie is a unit of energy, the heat needed to warm one gram of water by one degree Celsius; food energy is given in kilocalories, often written Calories.
- Dietary fiber
Dietary fiber is the part of plant foods, mostly carbohydrate, that human digestive enzymes cannot break down, so it reaches the large intestine intact.
- Electrolyte
An electrolyte is a substance that forms ions in water so the solution conducts electricity; in the body, it means charged minerals such as sodium.
