Study Notes
Fat-Soluble Vitamins
- Fat-soluble vitamins can lead to toxicity due to long storage in the body.
- Absorption of these vitamins requires dietary fat.
- Risk of deficiency in fat-soluble vitamins is heightened in individuals with Crohn's disease, cystic fibrosis, celiac disease, or those who have undergone intestinal bypass surgery.
- Liver disease patients must avoid exceeding the recommended intake of fat-soluble vitamins because of potential buildup.
Vitamin A
- Essential for vision, tissue growth, and embryonic development.
- Deficiency results in vision changes, xerophthalmia, and epithelial cell alterations.
- Rich food sources include fish liver oils, egg yolks, butter, cream, and yellow/orange vegetables like carrots and squash.
Vitamin D
- Vital for calcium and phosphorus utilization and assists in skin repair.
- Deficiency can lead to bone demineralization and, in severe cases, rickets.
- Excessive intake may result in hypercalcemia.
- Synthesized in the body through sunlight exposure.
- Found in fortified milk, cod liver oil, and eggs.
Vitamin E
- Preserves muscles, red blood cells, and maintains the myelin sheath.
- Deficiency can cause hemolytic anemia and nerve fiber damage affecting movement and vision.
- Found in vegetable oils and certain nuts.
Vitamin K
- Crucial for blood clotting and bone maintenance.
- Deficiency leads to prolonged bleeding times.
- Food sources include oils, liver, and leafy green vegetables like spinach and broccoli.
- Acts as an antidote to excess anticoagulants like warfarin.
General Vitamin Facts
- Vitamins are organic substances necessary in minute quantities for physiological functions.
- They do not become part of the body structure and should not exceed 150% of the RDA in supplements.
- Recommended for women of childbearing age and individuals over 50 to take synthetic vitamins from fortified foods.
Water-Soluble vs Fat-Soluble Vitamins
- Water-soluble vitamins include B complex and vitamin C.
- Fat-soluble vitamins consist of A, D, E, and K.
- Vitamins do not provide usable energy for the body.
Vitamin C
- Aids in tissue building, metabolic reactions, collagen formation, and iron absorption.
- Found in citrus fruits, tomatoes, peppers, and green leafy vegetables.
- Deficiency causes scurvy, leading to bleeding, joint pain, and weak bones.
B Vitamins Overview
- These include thiamin (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin, folate, and cobalamin (B12).
- B vitamins support various metabolic and physiological functions, including energy production and blood cell synthesis.
Deficiency Effects
- Thiamin deficiency can lead to beriberi with gastrointestinal and cardiovascular symptoms.
- Riboflavin deficiency presents as cheilosis and dermatitis.
- Niacin deficiency results in pellagra, characterized by skin lesions and dysfunction.
- Deficiency in folate leads to megaloblastic anemia and neural tube defects in pregnancy.
- Cobalamin deficiency primarily affects red blood cell production and can cause pernicious anemia, especially in strict vegetarians.
Important Sources
- Thiamin: meat, grains, legumes.
- Riboflavin: dairy, meats, green vegetables.
- Niacin: beef liver, nuts, legumes, and enriched grains.
- Pantothenic acid: organs, eggs, avocados.
- Pyridoxine: organ meats, grains.
- Biotin: eggs, milk, dark leafy greens.
- Folate: liver, green veggies, citrus fruits.
- Cobalamin: beef liver, shellfish, fortified grains.
