Essential Nutrients and Sources ~ Water
~ Carbohydrates
~ Protein
~ Fats
~ Micronutrients: Vitamins, Minerals
* The body's most basic nutrient need is water.
* The energy-providing nutrients are
carbohydrates, fats, and proteins.
* Micronutrients (vitamins and minerals) are
required in small amounts to metabolize the
energy-providing nutrients.
* The Nutritional Reference Guide lists major food
sources of calcium and iron
, Digestion, Absorption, and Major enzymes include ptyalin (salivary amylase),
Metabolism: Carbohydrates pancreatic amylase, and the disaccharides
End products are monosaccharides
Absorbed by the small intestine in healthy people
* Body breaks carbohydrates into glucose -
maintain blood levels
* Provide a readily available source of energy
~ Carbohydrates are sugars (simple carbohydrates)
and starches and fiber (complex carbohydrates).
~ Sugars may be monosaccharides (one molecule)
or disaccharides (double molecules). Glucose is
the most common monosaccharide.
~ Starches are insoluble, non-sweet forms of
carbohydrates that exist naturally in plants such as
grains, legumes, and potatoes.
~ Major enzymes of carbohydrate digestion include
ptyalin (salivary amylase), pancreatic amylase, and
the disaccharidases: maltase, sucrase, and lactase.
~ The desired end products are monosaccharides.
~ Carbohydrate metabolism is a major source of
body energy. Glucose circulates in the blood to
provide a ready source of energy. The remainder is
stored.
~ Insulin enhances the transport of glucose into the
cells.
~ Glucose is stored as either glycogen or fat.
Glycogen is a compound molecule of glucose
formed by the process called glycogenesis. While
most of the cells are capable of storing glycogen,
most is stored in the liver and skeletal muscles so it
is easily converted back to glucose. When glucose
cannot be stored as glycogen, it is converted to
fat.
~ Fiber is a complex carbohydrate derived from
