Study Notes
Vitamins Overview
- Vitamin C is not a fat-soluble vitamin; it is classified as water-soluble.
- Fat-soluble vitamins, when excessive, primarily accumulate in the liver.
- Enrichment is the process of replacing nutrients lost in food during processing.
Vitamin A
- Key function includes supporting vision and cellular development.
- Retalogical is not considered an active form of vitamin A, while retinol and retinal are.
Vitamin D
- The active form of vitamin D is known as calcitriol.
- Rickets is a disease linked to vitamin D deficiency, primarily in children.
Vitamin E
- Vitamin E is stored mainly in body fat.
- Excessive intake can interfere with blood clotting, especially when combined with blood thinners and aspirin.
Vitamin K
- Primarily responsible for the blood clotting process.
Vitamin B Complex
- Comprised of eight different compounds.
- Thiamin deficiency can lead to beriberi, while niacin is necessary for synthesizing fatty acids.
- Pyridoxal phosphate is a crucial co-enzyme for vitamin B6.
- The Recommended Dietary Allowance (RDA) for folate is 400 micrograms per day for adults; deficiency is linked to Spina Bifida and heart disease.
Other Vitamins and Nutrients
- Pantothenic acid is a component of acetyl CoA, essential for many metabolic processes.
- Raw egg whites may inhibit biotin absorption.
- Vitamin C deficiency causes scurvy, characterized by symptoms like fatigue and bleeding gums.
Storage and Absorption
- Water-soluble vitamins are not stored in the body, while fat-soluble vitamins can be stored in the liver for an extended period.
- Healthy livers can hold vitamin A for up to a year.
- Vitamin K deficiency in adults is rare and often occurs in those with fat malabsorption problems.
Dietary Sources and Effects
- Riboflavin sources include dairy, enriched grains, eggs, and organ meats.
- High doses of niacin can cause flushing, headaches, and liver damage.
- Excessive vitamin B6 intake can cause irreversible nerve damage.
Miscellaneous Facts
- Vitamin B12 absorption relies on intrinsic factor and can lead to weakness, fatigue, and nerve damage when deficient.
- Good sources of biotin are not primarily fruits and vegetables.
- Vitamin C aids in protecting cells from oxidative damage and may lower the risk of heart disease and certain cancers.
- Recommended daily intakes for vitamin C differ; 60 mg for men and 45 mg for women is incorrect.
- Choline is a nutrient with vitamin-like properties, crucial in metabolizing homocysteine and contributing to acetylcholine production.
Conditional Nutrients
- Conditional nutrients include inositol, carnitine, taurine, and lipoic acid, which may become necessary under certain conditions.
- Foods of animal origin contain retinoids, while plant sources provide provitamin A carotenoids like beta-carotene.
