Reducing the risk- current evidence
If there was a drug that reduced kidney
cancer risk by 19% with
– No known side effects
– Decreased risk of heart disease and diabetes
Should we know about it?
Should it be marketed and promoted?
Should we discuss it with health teams?
Would we want people of all ages to take
it in order to “stack the odds” in favour of
not developing cancer?
Cancers of 17 sites – 80% of incidence and deaths worldwide

Recommendations
Energy dense foods and drinks
Principally drinks with “added
sugar”•Colas, squashes, sodas
•Fruit juices (limited)
2007 to the future…•Milk Shakes (2160 kcals)
•Fruit Smoothies no sugar added… (120 to 190kcals)
•With “Health added” e.g. Orange Juice Drink with 'Five
Added Nutrients'
Sugary Drinks- definitions

Fast Foods
Readily available convenience foods
- Energy dense
- Consumed frequently
- Large portions
1420 Kcal
Fast foods- definitions
No Exercise trials with survivorship endpoints
Exercise is a safe and effective way to provide
rehabilitation for cancer survivors
Short term interventions HAVE demonstrated
– Improved aerobic capacity
– Strength
– Body composition
– Quality of life
– Reduced fatigue
– Emotional distress
– Lymphedema symptoms
Include resistance training for body composition
Physical activity
What are the current recommendations?
Aim to be active daily!• 150mins moderate intensity activity /wk in bouts of ≥10 mins
• Or 75 mins of vigorous activity / week
• Or a combination of the two
Activity to improve muscle strength ≥ 2 days / week
Older adults at risk of falls to incorporate activity to improve balance and coordination ≥ 2 days / week
Minimise time spent being sedentary (sitting) for extended periods
UK Department of Health, 2011
Walking + pedometers?
Pedometers have been identified as the single most effective method of physical activity promotion (Heath et al., 2012).
Plant foods
Five a day… minimum
Fibre from unprocessed cereals /whole
grains and/or pulses with every meal
Limit refined starchy foods (white
flour, pastry, biscuits, baked goods)
US Dietary Guidelines for Americans
3 x 16g servings of wholegrain per day
Equivalent to:
“Make half your grains whole”
UK: Median daily adult intake 20g and 17%
adults eat none*
30g 1 tbsp3 tbsp
*Mann et al 2014
Fruit and Vegetable portions
1. Which of the following contains 1 portion
fruit/veg
a) 6 slices cucumber
b) 1 grape
c) 2 tablespoons tomato ketchup
d) 7 strawberries
e) None of the above
Fruit and Vegetable portions
2. How many fruit and veg portions in a
salad which contains:
4 lettuce leaves, 2 slices cucumber, 2 slices
of tomato and one slice of beetroot
a) 0 portions
b) 1 portion
c) 2 portions
d) 3 portions
e) 4 portions
What is meant by five a day ?
Quantity, Variety and Quality???
Animal Foods•300g cooked (40g/day) =
400-450g raw per week
•500g cooked (70g/day) =
700-750g raw per week
•Red meat need not be a
daily food
•One average portion red
meat every other day
•Poultry, fish and eggs-
little risk
Processed meat..no level of intake not
associated with risk

Dietary Supplements
BEWARE!!!
57 to 87% US cancer survivors initiate
supplements after diagnosis
Unlikely to improve prognosis
May make things worseMay be a role for standard multi vitamins/minerals during
and after cancer treatments if defeciency or cannot take
meet nutritional needs through diet- not routine needs
Misinformation
Omega -3
Micronutrient testing
Organics
Deodorants/antiperspirants
One study doesn’t make a summer!
Lay beliefs (knock!)
Thinking of losing weight?
• A modest 5-10% weight loss MAINTAINED LONG TERM can
significantly improve a person’s health (and wellbeing)
• BUT
Improving health risks
Many men
think
slimming
and dieting
are just “for
women”
Men often prefer to control their weight through exercise
Camelon 24/03/09
Most men avoid weight loss groups
Weight-management for men through increasing
physical activity and eating a healthier diet
Free of charge, group-based programme
12, weekly sessions with ‘classroom’ education
and ‘training’ at Scotland's top football clubs
PLUS
Daily pedometer-based homework
THEN
Light touch ongoing maintenance to 12 months
(6 email prompts and 1 reunion session at club)
Appeals to men
1) Healthy eating, not a diet, focus on PA and alcohol
2) Football clubs, male-only, club community coaches
3) Interactive, informal, banter Gray, Hunt, Mutrie et al,

P5: Aye, it was brilliant.
P2: That’s one of the best things I’ve
ever

P4: To me, it’s life changing. It was life
changing, you know? Hopefully, you
know, that you know, it will keep it up.
I know I’m determined I will keep it
up.
Building the evidence
Conclusions
Current recommendations for people living
with cancer highlight
Body weight – building healthy bodies
Being Physically Active
Healthy diet, high in wholegrains and plant
foods, low in animal fats
For good health, well being and stacking the
odds against cancer recurrence
