Type 2 Diabetes: the pandemic waiting
to happen?
Pandemic
Extensively epidemic (Steadmans Medical Dictionary, 28th Ed)
An infectious epidemic
occurring worldwide or
over a very wide area,
crossing international
boundaries, and usually
affecting a large number of
people (Wikipedia, 2013)
Waiting to happen?

Type 2 diabetes (dietary) management
Glycaemic control → carbohydrate quantity & quality
Weight loss → calories
Lipid management → saturated vs. unsaturated fat
Blood pressure management → salt / alcohol
Overall dietary quality → fruit & veg, fibre
Low calorie,

• Structured diabetes education + patient empowerment
• Individualised, supportive approach
• Intense review as part of a behavioural lifestyle intervention (MDT approach)

Dietary approaches in Type 2 diabetes
Evidence for:
Low fat diets, low carbohydrate diets, high protein diets
Low glycaemic index/load diets
Mediterranean diet
Meal replacements
Very low calorie diets
“The true application of research findings can usually be found in the
author’s description of the participants’ usual diet before randomization.
The red meats, salty snacks, and sweets participants typically ate were
replaced with lower-fat protein sources, lower-fat dairy, whole grains—
fewer empty-calorie foods in place of more nutrient-dense foods” (Perry,
2005)
What do our patients want? Food based recommendations that can be easily
understood and translated into everyday life
![Page 18: 7th DIETS/EFAD Conference / Diabetes pandemic garda_25112013_website_final](https://reader034.vdocuments.site/reader034/viewer/2022042623/547a651ab4af9faf158b4aaf/html5/thumbnails/18.jpg)
It works!
Structured dietetic-led diabetes education programmes
ROMEO (Italy): Dietitian-led T2DM groups significantly improved
outcomes compared to a medically and pedagogically-led group (Trento, 2008)
X-PERT (UK): Improved HbA1c (-0.6 vs. -0.1%), weight (-0.5 vs.
1.1kg) + improved diabetes knowledge + fruit/veg intake (Deakin, 2006)
Intense lifestyle interventions
e.g. LookAhead
4 years:
Weight -6.2 v.s -0.88% (P <0.001)
Significantly better HbA1c, fitness,
BP, HDL, TAG
Gregg, 2012

really?

Benefits of modest weight loss in Type 2
diabetes

Key messages for clinical practice
1. Focus on calorie restriction, portion control + weight
management
2. Think more ‘algorithmically’ i.e. individualise approaches
and change the approach if it’s not working
![Page 22: 7th DIETS/EFAD Conference / Diabetes pandemic garda_25112013_website_final](https://reader034.vdocuments.site/reader034/viewer/2022042623/547a651ab4af9faf158b4aaf/html5/thumbnails/22.jpg)
Is it cost effective?
Lifestyle interventions? Yes, probably, at least in the shorter
term (Jacobs Van der Bruggen, 2009; DPP, 2012)
Report commissioned by the Dutch Association of Dietitians
in 2012 (ICAN Study):
For every €1 spend on dietary counseling, society gets a net €14 -
63 in return: €56 in terms of improved health, €3 net savings in
total health care costs and €4 in terms of productivity gains.
Need to gather more diverse data routinely
Less medication usage, improved dietary quality, improved quality of
life, less hospital admissions, less A&E visits, less hypoglycaemia, less
work absenteeism, reduced rates of progression to complications

Preventing Type 2 diabetes: the simple things
work
1. Weight loss (5-10%)
2. Reduce fat intake (<30%)
3. Reduce saturated fat intake
(<10%)
4. Increase fibre intake
(>15g/1000kcals)
5. Increase activity
(>4hrs/week)

Dietitians know best!
We understand the complex challenges that our patients
face when trying to manage their diabetes within an
increasingly obesogenic environment and overburdened
health care systems.
Clinical ↔ public health
![Page 28: 7th DIETS/EFAD Conference / Diabetes pandemic garda_25112013_website_final](https://reader034.vdocuments.site/reader034/viewer/2022042623/547a651ab4af9faf158b4aaf/html5/thumbnails/28.jpg)
Health 2020
Health2020 makes the case for investment in health and aims
to support action across government and society to improve
the health and well-being of populations and strengthen public
health.
Tackling Europe’s major disease burdens, including diabetes, is a
priority area within the policy.
This will require coordinated public health action and health
care system interventions, which must be underpinned by
supportive environments.
Innovation and leadership for health are at the core of Health
2020, and it encourages all stakeholders to take on new
responsibility and accountability for population health.
![Page 29: 7th DIETS/EFAD Conference / Diabetes pandemic garda_25112013_website_final](https://reader034.vdocuments.site/reader034/viewer/2022042623/547a651ab4af9faf158b4aaf/html5/thumbnails/29.jpg)
What we can do This provides an opportunity for dietitians, as specialists with a
unique insight and professional expertise in the area, to take
leadership roles in developing local and national public health
policies that support the aims of Health2020 for a healthier
society that will reduce the burden of type 2 diabetes.
Local, national, international diabetes advocacy groups
Local / national diabetes service planning / steering committees
Global Diabetes Survey
We can be a strong voice about what needs to change…
Health in all policies approach
Environmental planning
Food marketing
Unhealthy food taxation vs. healthy food subsidies

“Bubonic plague could not
be stopped by wishing
that the population were
less degenerate”
“There is no public outrage that
governments legislate to protect
through legislation in other contexts
e.g. seatbelts, fire escapes, crash
barriers. Yet startlingly few public health
policies are in place to protect us from
excess calorie consumption ”
