BALANCED DIET • Definition A balanced diet is one that provides all essential nutrients — carbohydrates, proteins, fats, vitamins, minerals, and water — in appropriate proportions to maintain health, growth, and energy.
• COMPONENTS Carbohydrates (55–60%): Main energy source (rice, wheat, cereals). Proteins (10–15%): Growth, repair, enzymes (pulses, milk, eggs, fish). Fats (20–25%): Energy reserve, absorption of fat-soluble vitamins (oils, nuts, ghee). Vitamins & Minerals: Regulatory functions, immunity, metabolism. Water & Fiber: Digestion, excretion, hydration, bowel health. • WHO PERSPECTIVE Emphasizes nutritional adequacy for all age groups. Advocates fortification (iodized salt, iron-folic acid tablets). Promotes nutrition education at community level
DEFICIENCY DISORDERS – CAUSES, CLINICAL FEATURES, TREATMENT & PREVENTION
1. PROTEIN-ENERGY MALNUTRITION (PEM) Cause: Inadequate protein & calorie intake. Clinical features: Kwashiorkor: Edema, fatty liver, skin/hair changes. Marasmus: Severe wasting, stunted growth. Treatment: High-protein diet, milk, pulses, nutritional supplements. Prevention: Breastfeeding, weaning with protein-rich foods, nutrition education
2. VITAMIN A DEFICIENCY Cause: Lack of vitamin A (retinol). Clinical features: Night blindness, xerophthalmia, keratomalacia. Treatment: Vitamin A supplementation (WHO recommends high-dose capsules). Prevention: Green leafy vegetables, carrots, liver, fortified foods
3. VITAMIN D DEFICIENCY Cause: Inadequate sunlight exposure, poor intake. Clinical features: Rickets (children), osteomalacia (adults). Treatment: Vitamin D supplements, calcium intake. Prevention: Sunlight exposure, fortified milk, fish oils
4. IRON DEFICIENCY (ANAEMIA) Cause: Poor dietary iron, chronic blood loss. Clinical features: Fatigue, pallor, breathlessness, spoon- shaped nails. Treatment: Iron-folic acid tablets, parenteral iron if severe. Prevention: Iron-rich foods (green leafy vegetables, meat, jaggery), fortification, deworming
5. IODINE DEFICIENCY Cause: Lack of iodine in diet. Clinical features: Goitre, hypothyroidism, cretinism in children. Treatment: Iodine supplementation. Prevention: Universal use of iodized salt.
6. VITAMIN C DEFICIENCY Cause: Lack of fresh fruits/vegetables. Clinical features: Scurvy (bleeding gums, poor wound healing). Treatment: Vitamin C supplementation. Prevention: Citrus fruits, guava, amla, tomatoes
7. VITAMIN B COMPLEX DEFICIENCY Examples:  Thiamine (B1): Beriberi (neuropathy, Edema).  Niacin (B3): Pellagra (dermatitis, diarrhea, dementia).  Folic acid/B12: Megaloblastic anaemia. Treatment: Specific vitamin supplementation. Prevention: Balanced diet with cereals, pulses, milk, meat, vegetables.
FAMILY PLANNING Definition Family Planning: Family planning refers to practices that help individuals and couples anticipate and attain their desired number of children and the spacing/timing of their births. Methods: Contraceptives (barrier, hormonal, intrauterine devices), sterilization, natural methods, and fertility awareness. WHO Emphasis: Family planning is a cornerstone of reproductive health, reducing maternal/infant mortality, preventing unintended pregnancies, and empowering women.
ROLE OF PHARMACIST IN FAMILY PLANNING 1. Education & Counselling • Provide accurate information on contraceptive methods, their use, benefits, and side effects. • Address myths and misconceptions (e.g., infertility fears, cultural taboos). • Counsel on safe sex practices and prevention of sexually transmitted infections (STIs).
2. Accessibility of Contraceptives • Ensure availability of contraceptives (condoms, oral contraceptives, emergency pills, IUD supplies). • Maintain confidentiality and a non-judgmental environment for clients. • Stock essential medicines for reproductive health
3. Community Health Role • Participate in public health campaigns (immunization + family planning integration). • Support government programs (National Family Welfare Program in India). • Act as a bridge between healthcare system and community, especially in rural areas.
4. Monitoring & Referral • Identify adverse effects of contraceptives (e.g., hormonal pill complications). • Refer patients to physicians for advanced methods (IUD insertion, sterilization). • Monitor compliance and encourage continuity of use.
5. WHO Consultative Group Perspective • Pharmacists are vital in task-sharing: expanding contraceptive services beyond doctors. • Promote emergency contraception awareness. • Encourage male participation in family planning.
