KEEPING HEALTHY - Diet and Exercise

Balanced nutritious food intake and doing some regular aerobics to help reduce the risk from some non-communicable diseases, obesity indexes, effects of diet deficiencies

Sub-index for this section on diet and exercise for good health

(1) What is a healthy balanced diet?

(2) What are the consequences of an unbalanced, unhealthy or inadequate diet?

(3) Metabolism, body mass and what are our energy requirement?, note on inherited factors

(4 Aerobic exercise reduces risk from some non-communicable diseases

(5) Obesity and measures of obesity - body mass index and waist-to-hip ratio

(6) Measuring the calorific value of foods, theoretical energy released on metabolising oil/fat

and Keeping healthy - non-communicable diseases - risk factors for e.g. CVD, cancers, obesity, diabetes
