Key knowledge: ●The role of nutrition in addressing the following conditions recognised in the NHPAs: o cardiovascular disease o diabetes mellitus o colorectal cancer o obesity o osteoporosis Taking into account, where relevant: o the function (as a determinant of health) and o major food sources of: protein carbohydrate (including fibre) fats (mono, poly, saturated and trans) water calcium phosphorus sodium vitamin D.
Classification of nutrients There are six (6) categories of nutrients needed for optimal health ● carbohydrates (including fibre) ● vitamins ● lipids (fats) ● minerals ● protein ● water Nutrients are further classified into 2 categories
VegetablesFruits Grain breadsCereals
Skins of vegetables Seeds of fruits Wholegrain foods such as breads, wheat bran, brown rice, nuts

SodiumFunction as a determinant of health Food Source Many foods have sodium added as a preservative /to add flavour Sodium plays a role in the regulation of water in the body (both water and blood) and blood volume Meats, fish, cheese, processed foods excess sodium can cause high blood pressure (hypertension), increasing risk of stroke (CVD) Excess can cause heart failure and kidney stones Excess can interfere with calcium use in the body, increasing risk of osteoporosis assists in muscle contraction, reducing the risk of muscle cramps Excess can cause nausea and vomiting
WaterFunction as a determinant of health Food Source Although water has no nutritional value water is vital for human survival Important for chemical reactions, digestion and waste removal Tap water, beverages (drinks), foods Component of blood Reduced levels can increase the risk of constipation, dehydration (fatigue, muscle cramps, headaches)
