Micronutrients Nutrients required in small amounts that are vital for health and include all vitamins essential for bodily functions. Recommended Dietary Allowance Daily intake level considered sufficient to meet the nutrient needs of nearly all healthy individuals in a group. Adequate Intake Estimated daily nutrient intake assumed to ensure nutritional adequacy when an RDA cannot be determined. Tolerable Upper Intake Level Maximum daily nutrient amount unlikely to cause adverse health effects for most people. Nutrient-Dense Foods Foods providing substantial vitamins and minerals with relatively few calories, supporting optimal health. Fortified Foods Products with added nutrients to address dietary gaps, often used when certain foods are avoided. Fat Soluble Vitamins Vitamins stored in body tissues, more stable, and present higher toxicity risk when consumed in excess. Water Soluble Vitamins Vitamins sensitive to heat, light, and water, not stored in the body, and excess amounts are excreted in urine. Vitamin Preservation Practices such as minimizing exposure to air, water, heat, and light to retain vitamin content in foods. Supplementation Use of concentrated nutrient products, often necessary for specific populations but risky if overused. Toxicity Adverse health effects resulting from excessive intake of certain vitamins, especially fat soluble types. Processed Foods Items often containing added sugars, artificial ingredients, and fewer beneficial nutrients compared to whole foods. Artificial Additives Substances such as colors, flavors, and preservatives added to foods, often found in processed or fortified products. Neural Tube Defects Birth abnormalities linked to insufficient intake of certain vitamins, notably folate, during pregnancy. Deficiency Condition arising from insufficient intake of essential vitamins, leading to health complications.
