    Study Notes

    Vitamins & Minerals

    • Vitamins contain carbon and are organic; Minerals do not have carbon and are inorganic.
    • Vitamins are coenzymes or precursors to coenzymes, while minerals are cofactors.
    • Vitamins are divided into water-soluble and fat-soluble, and minerals into macro minerals (major minerals) and micro minerals (trace minerals).
    • While vitamins are mostly safe in excess, mineral overdose can be toxic to kidney tubules, potentially leading to kidney failure.
    • Excess iron or copper is more likely to cause kidney damage than excess vitamins.

    Macronutrients & Micronutrients

    • Macronutrients are needed in large amounts per day and include carbohydrates, proteins, and fats.
    • Micronutrients are needed in smaller amounts and include vitamins and minerals.

    Water-soluble Vitamins

    • Include all B Vitamins (B1, B2, B3, B5, B6, B7, B9, and B12), and Vitamin C
    • B9 is the same as folate or folic acid.
    • Choline, an important nutrient, acts much like a water-soluble vitamin.

    Fat-soluble Vitamins

    • Include Vitamins A, D, E, and K.
    • Vitamin D is also considered a hormone.

    Minerals

    • Macro Minerals (Required in doses greater than 1 mg/day)
      • Calcium
      • Magnesium
      • Sodium
      • Potassium
      • Chloride
      • Phosphate
    • Micro Minerals/Trace Minerals (Required in doses less than 100–200 mg/day)
      • Iron (Ferrous and Ferric)
      • Iodide
      • Zinc
      • Copper

    Deficiencies

    • Macro Minerals
      • Deficiency can be life-threatening.
      • For example, low sodium can lead to coma and death.
      • High or low potassium can stop the heart.
    • **Micro Minerals **
      • Deficiency can be serious but not fatal like macro minerals.
      • For example, zinc deficiency can cause loss of taste and smell.
      • Calcium deficiency can lead to heart stopping during systole.

    Nutritional Deficiencies

    • Vitamin C: Scurvy, characterized by bleeding spots on the skin, cork-screw hair pattern, and connective tissue problems.
    • Vitamin B1: (Thiamine) Beriberi, with dry and wet types affecting the nervous and cardiovascular systems respectively.
    • Vitamin B9 (Folate) & Vitamin B12: Anemia
    • Vitamin B6 & Vitamin B12 & Vitamin E: Nerve problems
    • Vitamin K: Bleeding due to blood clotting issues
    • Vitamin D: Bone problems
    • Vitamin A: Night blindness, also called nyctalopia
    • Choline: Fatty liver, elevated ALT, and muscle weakness.

    Iron Deficiency

    • The most common nutritional deficiency worldwide.
    • Leads to iron deficient anemia.
    • Symptoms include fatigue, paleness.

    Heavy Metal Toxicity

    • Can lead to kidney damage:
      • Nephrotoxic acute tubular necrosis
      • Renal tubular acidosis
    • Common heavy metals include lead and mercury.

    Other Important Points

    • While there are many types of vitamins and minerals, each has a specific role in the body.
    • Understanding the differences between vitamins and minerals, their functions, and their deficiencies can give you a comprehensive understanding of human nutrition.
    • Always consult a healthcare professional for personalized nutritional advice.
