Vitamin D (Sunshine Vitamin) • Vitamin D is commonly known as: • The “sunshine” vitamin. • Vitamin D2 (Ergocalciferol) which is found in plants. • Vitamin D3 (Cholecalciferol) which can be obtained from sunlight via our skin.
Functions of Vitamin D • Vitamin D helps with increased Calcium absorption (small intestine) urinary calcium reabsorption (kidney) and Bone mineralization • Helps with the travel of calcium and phosphorous in the blood • Modulation of neuromuscular and immune function. • Reduction of inflammation.
Deficiency Symptoms and Diseases • Rickets and Osteomalacia are the classical vitamin D deficiency diseases • Rickets, is characterized by a failure of bone tissue to properly mineralize, resulting in soft bones and skeletal deformities • Osteomalacia, is characterized by fragile bones that significantly increases the risk of bone fractures
Deficiency Symptoms and Diseases • Osteoporosis results from inadequate calcium intakes • Vitamin D plays a role in the prevention of colon, prostate, and breast cancers hence, lack of this vitamin can trigger these diseases. • Vitamin D deficiency is also associated with heart disease and hypertension
Healthy Food Sources of Vitamin D • Some of the various food sources of Vitamin D are: • Fatty fish, Egg, 1 whole (vitamin D is found in yolk) fortified milk, cod liver oil, fortified orange juice, fortified cereals, mushrooms, fortified margarine, beef liver, swiss cheese. • In addition, vitamin D can be obtained from sunlight and you can get sunlight for free by exposing your skin to the sun.
DRI for Vitamin D • Infants 0-6 months 5 (mcg) Micrograms • 7-12 months 5 (mcg) • Children 1-3 years 5 (mcg) • 4-8 years 5 (mcg) • Males 9-13 years 5 (mcg) • 14-18 years 5 19-30 years 5 (mcg) • 31-50 years 5 (mcg) • 51-70 years 10 (mcg) • > 70 years 15 (mcg)
DRI for Vitamin D • Females 9-13 years 5 (mcg) • 14-18 years 5 (mcg) • 19-30 years 5 (mcg) • 31-50 years 5 (mcg) • 51-70 years 10 (mcg) • > 70 15 (mcg)
DRI for Vitamin D • Pregnancy < 18 years 5 (mcg) • 19-30 years 5 (mcg) • 31-50 years 5 (mcg) • Lactation 18 years 5 (mcg) • 19-30 years 5 (mcg) • 31-50 years 5 (mcg)
DRI for Vitamin D • 200 IU is equivalent to 5 mcg. • Margarine, fortified, 1 Tablespoon*****60 IU • Sardines, canned in oil, drained, 13/4 ounces*****250 IU • Tuna fish, canned in oil, 3 ounces*****200 IU • In order to meet the recommended DRI, we will need to consume 60 IU of Margarine,
DRI for Vitamin D • 2 ounces of Sardines = 40 IU • And 1.5 ounce of Tuna = 100 IU • A combination of these 3 foods and serving sizes will meet the DRI for vitamin D within the children age group and age 50.
Facts about Vitamin D • When exposed to sunlight (Ultraviolet Rays) , Vitamin D3 (Cholecalciferol) is absorbed via the skin by using 7 dehydrocholesterol (a crystalline steroid alcohol) • Vitamin D is the most vital vitamin in the human body to boost the rate of absorption of the essential minerals calcium and phosphorus from the intestines.
