Dietary Guidelines

Dietary Guidelines - Guiding Good Grub

• Authorities: ICMR & NIN.
• Objectives: Promote health, prevent deficiencies, reduce NCD risk.
• Target: General population; specific advice for age, gender, physiological states.
• Key Reference Intakes:
  • EAR (Estimated Average Requirement): Meets needs of 50% of a group.
  • RDA (Recommended Dietary Allowance): Meets needs of 97-98% healthy individuals. $RDA = EAR + 2SD_{EAR}$.
  • UL (Tolerable Upper Intake Level): Highest daily intake unlikely to pose health risks.
• FBDG (Food Based Dietary Guidelines): Practical, food-based advice translating nutrient needs into daily food choices.

  ⭐ ICMR-NIN guidelines emphasize a balanced diet with variety, moderation, and limiting ultra-processed foods.

Food Groups & Portions - Balanced Bite Blueprints

A balanced diet ensures optimal nutrient intake. Key food groups: 📌 Can People Make Fresh Veggie Fajitas Now? (Cereals, Pulses, Milk/Meat, Fruits, Vegetables, Fats/Oils, Nuts/Seeds)

• Cereals & Millets: Main energy source.
• Pulses & Legumes: Key protein source.
• Milk & Meat Products: Protein, calcium, Vit B12.
• Fruits & Vegetables: Vitamins, minerals, fiber. Aim for 5 servings/day.
• Fats & Oils: Concentrated energy, EFAs. Use sparingly.
• Nuts & Seeds: Good fats, protein.

My Plate for India (ICMR-NIN):

• Visual guide for balanced meals, integrating food pyramid principles.
• Advocates portion control: e.g., ½ plate fruits & vegetables, ¼ protein, ¼ cereals.

⭐ Exam Favourite: My Plate for India recommends that approximately 50-60% of total daily energy should be derived from carbohydrates, primarily complex ones.

Nutrient Recommendations - Macro & Micro Musts

• Energy: Adults ~2000-2500 kcal/day (NIN); varies by activity, age, gender, physiological state.
• Macronutrients (% Total Energy):
  • Protein: 0.8-1 g/kg ideal body weight daily; higher in growth, pregnancy.
  • Fats (Total 20-30%): SFA <10%, MUFA 15-20%, PUFA 5-10%, Trans fats <1%.
  • Carbohydrates: 50-60%.
• Key Micronutrients (RDAs vary; Indian context deficiencies):
  • Vitamins: A (xerophthalmia), D (rickets/osteomalacia), C (scurvy), B-complex (e.g., B12, Folate).
  • Minerals: Iron (anemia), Calcium (osteoporosis), Iodine (IDD).
• Other Essentials:
  • Salt (NaCl): <5 g/day.
  • Added Sugar: <10% (ideally <5%) total energy.
  • Water: Adequate intake (~2-3 L/day).

⭐ Iron RDA for pregnant women (ICMR): 40 mg/day elemental iron.

Special Groups & Habits - Eating Right Always

• Pregnancy: ↑ +350 kcal/day; Iron & Folic Acid (IFA) vital for fetal development.
• Lactation (0-6m): ↑ +600 kcal/day to support milk production. (6-12m: +520 kcal/day).
• Infancy:
  • Exclusive Breastfeeding (EBF): Ideal for first 6 months.
  • Complementary Feeding: Start after 6 months, continue breastfeeding.
• Childhood & Adolescence: Balanced, varied diet for growth; adequate protein, Calcium, Iron.
• Elderly: Nutrient-dense foods; maintain hydration; sufficient Calcium, Vitamin D.

  ⭐ Elderly often require fewer calories but higher nutrient density due to reduced BMR and activity.

• Food Safety:
  • Hygiene (handwashing), safe storage (refrigeration), thorough cooking.
  • Adulteration awareness (e.g., FSSAI checks).
• Physical Activity (Adults): ≥150 min/week moderate-intensity or ≥75 min/week vigorous-intensity aerobic exercise. oka

High‑Yield Points - ⚡ Biggest Takeaways

• NIN (National Institute of Nutrition) issues Dietary Guidelines for Indians (DGIs).
• Aim for balanced diet: Carbs 50-60%, Protein 10-15%, Fat 20-30% of total energy.
• Daily dietary fiber intake should be 25-40g.
• Limit added sugar to <10% total energy; salt intake <5g/day.
• Consume ≥5 servings (approximately 400g) of fruits & vegetables daily.
• Practice exclusive breastfeeding for the first 6 months; continue up to 2 years with complementary foods.
• Prioritize fortified foods like iodized salt and Vitamin A fortified oil to combat micronutrient deficiencies.
