Targeted Behaviours | Rationale/Evidence |
---|---|
Body Fatness: Be as lean as possible within the normal weight range, avoid weight gain and increases in waist circumference | Maintenance of a healthy weight may be one of the most important ways to protect against cancer recurrence and other common chronic diseases, including hypertension, stroke, type 2 diabetes and coronary heart disease [40] |
Physical Activity: Be moderately physically active, equivalent to brisk walking, for at least 30 min per day; As fitness improves, aim for 60 min or more of moderate, or for 30 min or more of vigorous, physical activity every day | Physical activity of longer duration or greater intensity is more beneficial; All forms of physical activity protect against some cancers, as well as against weight gain, overweight, and obesity [40] |
Diet: Eat mostly foods of plant origin; limit consumption of energy-dense foods; avoid sugary drinks, limit intake of red meat and avoid processed meat | An integrative approach to the evidence shows that most diets that are protective against cancer are mainly made up from foods of plant origin; Consumption of energy-dense foods and sugary drinks contributes to obesity; An integrated approach to the evidence also shows that many foods of animal origin are nourishing and healthy if consumed in modest amounts. |
Alcohol: If alcoholic drinks are consumed limit consumption to no more than one drink per day | The evidence on cancer justifies a recommendation not to drink alcoholic drinks. Other evidence shows that modest amounts of alcoholic drinks are likely to reduce the risk of coronary heart disease [40] |
