Vitamins
do not contribute to energy production
Vitamins facilitate ..
release of energy from carbohydrate, fat and protein
How many vitamins are there
13
Vitamins are divided into ..
water soluble and fat soluble categories
Water soluble vitamins are ..
- vitamin C (ascorbic acid)
- the 8 B vitamins
What are the 8 B vitamins
- thiamin (B1)
- riboflavin (B2)
- niacin (B3)
- pantothenic acid (B5)
- pyridoxine (B6)
- biotin (B7)
- folic acid (B9)
- B12 (cobalamine)
Fat soluble vitamins
A, D, E, and K
What vitamin plays major role in tissue building
vitamin C
The various B vitamins are involved in ..
different metabolic processes that release energy (catabolism) or synthesize nutrients (anabolism).
Vitamin A enables the ..
eye to see in dim light
Vitamin D facilitates ..
absorption of calcium in the digestive tract
Vitamin E acts as an ..
anti oxidant that protects various organs from destructive compounds
Vitamin K facilitates ..
blood clotting and helps stop bleeding
Vitamins function only if they are..
intact
Due to organic nature they are vulnerable to ..
destruction by heat, light, storage conditions and chemical agents
Strategy of cooking vegetables at moderate temperatures, using small amounts of water and short times help to ..
preserve nutrients
Processing typically results in nutrient loss, foods may have nutrient added back though process called..
enrichment
Food may also be fortified with nutrients as an attempt to..
reduce the incidence of a specific nutrient deficiencies
Minerals (inorganic nutrients)
- constitute an essential component of bones and teeth (especially calcium)
- also found in body fluids where they influence properties of the fluids
Minerals do not yield..
energy but act as cofactors in energy yielding reactions
16 minerals are currently known to be ..
essential in human nutrition and can be broken down into 2 groups
Major minerals are..
calcium (Ca), phosphorus (P), potassium (K), sodium (Na), chloride (Cl), magnesium (Mg) and sulphur (S)
Trace minerals are ..
iron (Fe), iodine (I), zinc (Zn), chromium (Cr), selenium (Se), fluoride (F), molybdenum (Mb), copper (Cu) and manganese (Mn)
Minerals are ..
- indestructible due to their inorganic nature
- heat stable and can impact chemical/physical propertied of foods
