Fat-Soluble Vitamins are vitamins A,D,E, and K and dissolve in fat Water-Soluble Vitamins are the B-complex vitamins and vitamin C and dissolve in water Toxicity is a poisonous condition
3
A vitamin is an organic compound needed in tiny amounts as a nutrient to regulate body processes Have no calorie value because they yield no energy Vitamins assist with ◦ Nutrient metabolism ◦ Energy production & release ◦ Tissue maintenance ◦ Normal digestion ◦ Infection resistance
4
1912 Casmir Funk coined the world vitamine ◦ Vita means life ◦ Amine- a certain chemical structure that contains nitrogen ◦ E was dropped to avoid the chemical structure of proteins or confusion of the compound Vitamins help the body release energy needed for physical activity 13 known vitamins ◦ Most referred to a letter A,C,D,E and K ◦ Most of the B vitamins are known by name Riboflavin, thiamin, niacin ◦ Different vitamins do not share a typical molecular structure
5
Provitamins are compounds that are not vitamins, but the body can convert them into the active form of a vitamin. ◦ EX- beta-carotene is a PV for vitamin A Found in deep yellow & deep green fruits and veggies 2 Main causes of vitamin deficiency diseases 1)Sufficient amount of a vitamin in the diet 2)Failure of the body to absorb vitamin Pregnant women need larger amounts of many nutrients including most vitamins
6
Necessary for the formation of healthy epithelial tissue, Epithelial cells are the surface cells that line the outside of the body. Keep skin & hair healthy, keeps eyes free from dryness and infections, helps the lining of the lungs & intestines stay moist & resistant to disease, healthy eye sight Night blindness- eyes adapt slowly to darkness & night vision becomes poor RDA-900 micrograms for males 14 & older RDA-700 micrograms for females 14 & older
7
People who drink little milk or eat few vegetables may show signs of vitamin A deficiency ◦ Night blindness ◦ Dry, scaly skin ◦ Fatigue Vitamin A Toxicity Symptoms ◦ Severe Headaches ◦ Bone Pain ◦ Dry kin ◦ Hair Loss ◦ Vomiting ◦ Liver Damage
8
Unique fat-soluble vitamin With direct exposure of sunlight the body can make all the vitamin D it needs Helps regulate the levels of calcium in the blood stream Controls blood calcium levels Plays a role in maintaining all body tissues (AI) Adequate intake for VD is 5 micrograms (200 IU) per day for 50 & older. The Ai is higher for the older ones Helps avoid developing porous, fragile bones
9
Inhibits vitamin D production- filters sunlight ◦ Clouds ◦ Smog ◦ Window glass ◦ Sunscreen ◦ Heavy clothing Food sources containing vitamin D ◦ Fatty fish ◦ Fish oils ◦ Eggs ◦ Butter ◦ Margarine ◦ Vitamin D fortified milk
10
Adequate intake for vitamin D ◦ 5 micrograms(200 IU) per day for 50 and older ◦ Helps avoid developing porous fragile bones Light skinned people can make enough vitamin D to meet the body’s needs in 15 minutes Dark skinned people take longer time to produce the same amount
11
Effects and Deficiencies of V.D. ◦ Rickets - Deficiency disease in children caused by a lack of vitamin D ◦ Without VD not enough calcium is deposited in bones Causes bones to be soft & misshapen Leg bones may bow in or out Chest bones may bulge outward
12
Most advertised vitamin Helps maintain healthy immune & nervous systems Function in body as antioxidants Antioxidants- substances that react with oxygen to protect other substances exposure Help deactivate or transform free radicals Free Radical – unstable oxygen molecule Without V.E. tissue damage can lead to disease RDA is 15 milligrams per day for males and females for 14 and older
13
Best Sources ◦ Vegetable oils ◦ Some fruits & vegetables ◦ Margarine ◦ Wheat germ ◦ Multigrain cereals ◦ Nuts ◦ Canola Oil & salad dressings High temperatures destroy V.E. ◦ Foods processed with high heat lost the V.E.
14
Deficiency ◦ Babies-weak & listless ◦ Adults-speech, vision, and muscle coordination ◦ Less toxic than other fat-soluble vitamins ◦ Large doses Digestive problems Nausea May interfere with blood clotting
15
Main function- to make proteins needed in coagulation of blood Coagulation – clotting-process that stops bleeding Needed to make protein ◦ Helps bones collect the minerals they need for strength 14 to 18 males & females the AI for V.K. is 75 micrograms per day Good sources of V.K. ◦ Green leafy veggies ◦ Liver ◦ Fruits ◦ Milk ◦ Meat ◦ Eggs ◦ Grain products Newborns can be at risk for V.K. deficiency Toxicity is rare
16
Plays a role in energy metabolism Required for normal functioning of the nerves & muscles they control More calories you burn more thiamin you need 14-18 have high daily calorie needs RDA-Males-1.2 milligrams per day RDA-Females-1.0 milligrams per day
17
Sources ◦ Whole grain breads ◦ Cereal ◦ Refined grain products ◦ Pork products ◦ Dried beans Nuts Seeds Body doesn’t store much thiamin so it needs to be enriched everyday Beriberi- deficiency disease-body cant perform the tasks required for everyday living
18
Helps body release energy from carbohydrates, fats, & proteins Need it for healthy skin & normal eyesight Late teen males & females 1.8 and 1.3 milligrams Sources ◦ Milk ◦ Milk products ◦ Enriched whole grain cereals ◦ Meats ◦ Poultry ◦ Fish Deficiencies ◦ Inflamed tongue ◦ Cracked skin around the corners of the mouth ◦ Various eye disorders ◦ Mental confusion
19
All types are water-soluble Involved in energy metabolism Helps keep skin & nervous system healthy Promotes normal digestion RDA-Males 14 to 18- 16 milligrams daily RDA-Females 14 to 18- 14 milligrams daily Can be toxic with too much consumed through supplements ◦ Dilated blood vessels on surface of skin ◦ Niacin flush Nausea Dizziness Low blood pressure
20
Sources ◦ Whole grain ◦ Enriched breads ◦ Cereals ◦ Meat ◦ Poultry ◦ Nuts Deficiencies ◦ Pellagra Symptoms Diarrhea Dermatitis (dry, flaky skin) Dementia (insanity) Death Poor appetite weight loss Weakness
21
B complex vitamin Functions ◦ Promotes growth ◦ Critical to the metabolism ◦ Synthesizing # of vital substances in body Ai-14 and up-5 milligrams per day Effects ◦ Rarely a problem ◦ Toxicity is rare
22
Function ◦ Helps the release of energy from carbohydrates, fats, proteins ◦ Helps the body makes fats & glycogen ◦ No RDA ◦ Ai-males & females 14 to 18- 25 micrograms per day Sources ◦ Egg yolks ◦ Yeast ◦ Beans ◦ Nuts ◦ Cheese ◦ Liver Deficiencies ◦ Abnormal heart rhythms ◦ Pain ◦ Weakness ◦ Nausea ◦ Loss of appetite ◦ Dry, scaly skin ◦ Hairless
23
Functions ◦ Synthesizing nonessential amino acids ◦ Needed to convert the amino acid to tryptophan to niacin ◦ Helps make protein Allows red blood cells to carry oxygen ◦ Affects health of immune & nervous system ◦ RDA males 14-50- 1.3 milligrams per day females 14-18- 1.2 milligrams per day Females through age 50- 1.3 M&F 50 and up increases
24
Sources ◦ Meats ◦ Fish ◦ Poultry ◦ Dairy products ◦ Some fruits & Veggies ◦ Bananas ◦ Cantaloupe ◦ Broccoli ◦ Spinach Deficiencies ◦ Rare ◦ Poor amino acid & protein metabolism ◦ Skin disorders ◦ Fatigue ◦ Irritability ◦ Convulsions Toxicity ◦ Large doses ◦ Numbness in hands & feet
25
- B vitamin function - Help synthesize DNA - Without it cannot divide to form new cells. - Important to women with child beating age. RDA 14 and up 400 micrograms per daily RDA-pregnant people need 600 milligrams
26
Sources - Dark green leafy wages - Liver - Legumes - Oranges - Cantaloupe - Broccoli Deficiencies - Increase risk of neural tube damage.
27
- helps Folate function - needed to growth - Maintenance of healthy nerve tissue - Formation of normal red blood cells - Needed to release energy from fat RDA-m-f-14 and up-2.4 Micrograms/day Sources -meat -Poultry -Fish - Eggs- dairy products
28
- assists in formation of collagens - proteins substances holds cell Together - healthy - antioxidant - cartilage - muscles - Blood vessels - Increasing iron and calcium observation - vital to immune system
29
Sources Deficiencies - Citrus fruits - Scurvy - Cantaloupe - Tiredness - Strawberries - weakness - sweet peppers - shortness of breath - Broccoli - aching bones - Cabbage - lack of appetite - Potatoes
30
Absorption- passage of nutrient from the digestive tract into the circulatory or lymphatic system - most absorption happens in small Intestine- covered with villi-tiny, finger like projection that give velvety texture - Water – soluble nutrients- dissolve in water - Fat- soluble nutrients-dissolve in fat metabolism.
31
all chemicals changes that occur as cells produce energy and material needed to sustain life. cells use compounds for energy or store to replace cells. Stores energy as adenosine triphosphate (ATP) Waste removed through urinary system factor affecting digestion and absorption Eating habits- need factor Emotions- reduce stress
32
Food allergies- reaction Physical activity- helps with digestion and metabolism. Hereditary - 25% of the factors - beyond your control: genetic - staying good physical health can help Health- promoting choices - choose healthy life style - control diet
33
- eat 3 or more regular speed meals - balanced nutrients - sleep 8-9 hours daily - healthy weight - stay active - DO NOT SMOKE - Avoid drinking alcohol beverages - Drug free - Resist negative peer pressure positive peer pressure Negative peer pressure Self- confidence
34
Factors that contribute to diseases ( present action and altitude are shaping the person you will be in the future). Risk factors- behavior that influences a person chance of being in reduced or getting a disease Unhealthy lifestyle choices lifestyle choices account for half of the contribution to head disease, cancer and strokes
35
others include nutritional choices(over eating fats and oils), stress management, exercise Poor environment quality - 1/5 of risk factors - refers to the state of the physical world around you - water you drink, air you breathe, food you eat proper shelter. - jobs hazards – dry wall dust, instruction inadequate health care - about 10% of risk - try for correct diagnosis or not searching a diagnosis - not getting regular check up - not following doctors advice.
