Verified Answers!!
Nutrients
chemical compounds in foods to provide fuel for energy, growth, and maintenance, and to
regulate body processes
Six classes:
Macronutrients: Carbohydrates, fats, protein
Micronutrients: Vitamins, minerals, water
non nutrient compounds
that contribute to health and may play a role in fighting chronic diseases
Macronutrients
energy-yielding nutrients needed in higher amounts
Carbohydrates
Classification:
Monosaccharides, e.g.
Glucose, Fructose, galactose
Disaccharides, e.g. Sucrose, lactose
Complex carbohydrates
Lipids
Classification:
Triglycerides: Made of fatty acids and glycerol Phospholipids: Made of fatty acids and a
phospahte head Sterols
Proteins
Structure
Amino acids (essential vs not essential)
, Peptides
Proteins (with specific configuration
how to calculate energy
Multiply the total grams of a nutrient by the number of calories per gram
Micronutrients
They are needed in small amounts
and together are essential for
physiological functions.
²Dietary essential nutrients - We
cannot create them!
² Vitamins
² Minerals
² Trace Elements
²Non-fuel nutrients
²Insufficient intake can cause diseases!
water soluble minerals vs fat soluble
Fat-soluble:
² Vit A, D, E, K
² absorbed with fat and stored in fat
tissue
Water-soluble
² Vit C & B complex (B1, B2, B3, B5, B6,
B7, B9, B12)
² cannot be stored in the body in large
quantities
Minerals
Inorganic micronutrients with diverse
biological functions, i.e.
