This document discusses food and public health, with a focus on the prevention of chronic diseases through population-level interventions targeting nutrition and lifestyle. It summarizes the experience of the North Karelia Project in Finland, which demonstrated that comprehensive community programs can successfully change risk factors like diet, physical activity and smoking rates. As a result, the project saw major declines in cardiovascular disease and mortality in the region. The document advocates for public health strategies that combine personal responsibility with supportive public policies to make healthy choices easier. Partnerships between governments, civil society and the private sector are also emphasized.

Preventable Diseases
Medical evidence for prevention exists.
Population-based prevention is the most
cost-effective and the only affordable option
for major public health improvement in NCD
rates.
Major changes in population rates can take
place in a surprisingly short time.

27. North Karelia Project
Principles for Defining
the Intermediate Objectives
• Due to the chronic nature of CVD,
the potential for the control of the problem
lies in primary prevention
• The risk factors were chosen on the basis of
best available knowledge:
- previous studies
- collective international recommendations
- epidemiological situation in North Karelia
• Chosen risk factors:
- smoking
- elevated serum cholesterol (diet)
- elevated blood pressure
NORDIC FOOD WEEK 19.9.2007

28. From Karelia to National Action
• First province of North Karelia as
a pilot (5 years), then national action
(1972–77)
• Continuation is North Karelia as
national demonstration (1977–95)
• Good scientific evaluation to learn of
the experience
• Comprehensive national action

Conclusions from the North
Karelia Project
• A comprehensive, determined and
theory-based community program can
have a meaningful positive effect on risk
factors and life styles
• Such changes are associated with respective
favourable changes in chronic disease rates
health of the population
and
• A major national demonstration program can be a
strong tool for favourable national development in
chronic disease prevention
and health promotion

58. Experience in Finland
• People are interested in the health message
• People attempt and make great changes in
their diet
• Food industry adopts and supports the new
trends; health is a major driver for product
development and marketing
• Health claims, nutrition labelling and
information important

60. Finland Has Shown
Prevention of major chronic diseases is possible and pays off
Population based prevention is the only cost effective and
sustainable public health approach to chronic disease control
Prevention calls for simple changes in some lifestyles
(individual, family, community, national and global level action)
Influencing national diets and lifestyles is a key issue
Many results of prevention occur surprisingly quickly
(CVD, diabetes) and also at relatively late age
Comprehensive action, broad collaboration with dedicated
leadership and strong government policy support
