Micronutrients and Digestive Health

Micronutrients and the Digestive System

• Vitamins and minerals function, sources, toxicity, and deficiency are key aspects of a balanced diet.
• Folic acid (B9) is crucial for DNA synthesis, cell division, and red blood cell formation.
  • Sources include leafy greens and legumes.
  • Deficiency can lead to neural tube defects and anemia
  • Toxicity can mask B12 deficiency.
• Vitamin B12 plays a crucial role in nerve function and red blood cell production.
  • Sources include meat, poultry, fish, and dairy.
  • Deficiency leads to anemia and nerve damage.
  • Vegans and vegetarians may be at risk of deficiency.
• Vitamin C acts as a powerful antioxidant, protects cells from damage, aids iron absorption and may reduce cancer risk.
  • Sources include citrus fruits, berries, and peppers.
  • Deficiency can cause scurvy, with symptoms like weakness and bleeding gums.
  • Toxicity is excreted through the urine.
• Vitamin A promotes vision, immune function, and cell growth.
  • Sources include liver, sweet potatoes, and carrots.
  • Deficiency can lead to night blindness and weakened immunity.
• Vitamin D supports strong bones, reduces heart disease risk, and prevents certain other diseases.
  • Sources include sunlight and fatty fish.
  • Deficiency in children can result in rickets, and in adults, osteoporosis
  • Megadoses of Vitamin D supplements can be toxic.
• Vitamin E is an antioxidant important for reproductive health, nerve and muscle function, and immunity.
  • Sources include nuts, seeds, and vegetable oils.
  • Deficiency can cause muscle weakness and vision problems.
  • Toxicity is rare and can interfere with blood clotting.
• Vitamin K helps prevent blood clotting and promote bone health.
  • Sources include leafy greens, broccoli, and soybeans.
  • Deficiency can cause bleeding problems, common in newborns.
• Calcium is essential for bone health, muscle function, and nerve transmission.
  • Sources include dairy, leafy greens, and fish.
• Iron is the protein in red blood cells that carries oxygen through the body.
  • Sources include red meat, beans, and spinach
  • Deficiency results in anemia and fatigue.
  • Toxicity can lead to organ damage.

Electrolytes

• Electrolytes (sodium, potassium, and chloride) are crucial for fluid balance, nerve, and muscle function.
  • Electrolytes can be obtained from table salt, fruits, and vegetables
  • Deficiency can lead to muscle cramps, weakness, and irregular heartbeats.
  • Excess intake can have health consequences, such as high blood pressure.
• Zinc supports immune function, wound healing, and cell growth.
  • Sources include meat, shellfish, and nuts.

Digestion

• The digestive system breaks down food into absorbable parts for the body.
• The process of digestion involves both mechanical breakdown (chewing, mixing) and chemical breakdown (enzymes).
• Carbohydrates are broken down into simple sugars by enzymes like amylase.
• Proteins are broken down into amino acids by enzymes like protease.
• Fats are broken down into fatty acids and glycerol by enzymes like lipase with the help of bile.

Food Labeling

• Food labels provide essential information about products, enabling informed dietary choices.
• Labels can help manage certain dietary needs like diabetes, hypertension, etc
• Labels often include allergen information and nutritional content relevant to a balanced diet.
• Labels are crucial for compliance with food safety guidelines

Understanding Food Labels

• Understanding the % Daily Value (DV) on labels helps consumers understand how a portion of food fits into the daily diet.
• Setting personal goals based on % DV is crucial to manage nutrition, like lowering sodium or increasing fiber.
• Balancing nutrients and comparing products using % DV help in choosing healthy options.
