Study Notes
Nutrition and Health
- Fruits and vegetables are the main sources of “GLOW” foods, which are essential for promoting body immunity and regulatory functions.
- Fortified foods, including iodized salt, are also good sources of “GLOW” foods.
Nutrients in Food
- Nutrients are substances contained in food that nourish the body and are required to maintain general health and physiological functions.
- There are three major categories of nutrients: macronutrients, micronutrients, and water.
Macronutrients
- Macronutrients are required in large amounts and include:
- Carbohydrates: primary source of energy, including starches, fiber, and sugars.
- Proteins: body-building foods required for growth, maintenance, and repair of tissues.
- Fats/oils: provide energy, build body cells, and facilitate the absorption and use of fat-soluble vitamins.
Carbohydrate Requirements
- Individual carbohydrate requirements vary according to age, sex, physical activity level, and physiological status.
- The recommended daily carbohydrate intake should provide about 45% to 65% of the total body energy/calorie requirements of 2000–3000 kilocalories (kcal).
Protein Requirements
- The recommended intake of protein each day is about 1 gram per kilogram of body weight.
- Extra protein is required during illness, convalescence, and after surgery.
Classification of Foods
- Foods can be classified according to their functions in the body:
- Energy-giving foods (“GO” foods): rich in carbohydrates and fats, providing energy to the body.
- Body-building foods (“GROW” foods): rich in protein, helping to maintain life and promote growth, repair, and maintenance of body tissues.
- Protective (“GLOW” foods): rich in minerals and vitamins, essential for promoting body immunity and regulatory functions.
Fats and Oils
- Fats and oils are derived from both animal and plant sources and are rich in energy.
- They can be divided into saturated and unsaturated fatty acids, with saturated fats increasing the risk of heart disease.
Dietary Fibre
- Dietary fibre increases the body’s sense of satisfaction, protecting against constipation and helping to slow the body’s absorption of sugar and cholesterol.
- Main sources of dietary fibre include whole grains, vegetables, legumes, and fruits.
Micronutrients
- Micronutrients are required by the body in small amounts and include vitamins and minerals.
- Vitamins are organic compounds that perform specific metabolic functions in the body, divided into fat-soluble and water-soluble vitamins.
- Minerals are required for normal functioning of body processes, including growth, development, water balance, and neurological processes.
Water
- Water maintains fluid balance, cell turgidity, and is a solvent for certain nutrients, used in removing excreta and keeping parts of the body moist.
- Drink at least 2-3 litres of water per day, especially in hot weather, to avoid dehydration.
Pharmacy Practice and SI Units
- In pharmacy practice, cm³ is considered equivalent to milliliter, but the symbol cc for cubic centimeter is not an accepted SI symbol.
- Decimal fractions are used, not common fractions, and zeros should be placed in front of leading decimal points to prevent medication errors.
Use of SI in Pharmacy
- The SI system is used to manufacture and label pharmaceutical products, write, fill, and compound prescriptions and institutional medication orders, and express clinical laboratory test results.
- Drug doses are typically administered in milligram or microgram amounts and prepared in solid dosage forms or in a stated volume of a liquid preparation.
- Doses for certain drugs are calculated on the basis of body weight and expressed as mg/kg.
Measure of Length
- The meter is the primary unit of length in the SI system.
- The table of metric length includes units such as kilometer, hectometer, dekameter, decimeter, centimeter, millimeter, micrometer, and nanometer.
Measure of Volume
- The liter is the primary unit of volume in the SI system.
- The table of metric volume includes units such as kiloliter, hectoliter, dekaliter, liter, deciliter, centiliter, milliliter, and microliter.
Measure of Weight
- The primary unit of weight in the SI system is the gram, which is the weight of 1 cm³ of water at 4°C.
- The table of metric weight includes units such as kilogram, hectogram, dekagram, gram, decigram, centigram, milligram, microgram, nanogram, picogram, and femtogram.
Prescription Writing Style using SI
- Quantities of weight are usually written as grams and decimals of a gram, and volumes as milliliters and decimals of a milliliter.
Fundamentals Computations
- To reduce SI units to lower or higher denominations, use a unit position scale by moving the decimal point one place to the right or left.
