50 years ago in Finland ...
In 1972, as people realized that it was not
normal to suffer from chest pain before the age
of 50, a national community-based program
was set up to reduce the risk factors for
cardiovascular diseases
People were educated to pay attention to health related issues, particularly smoking and diet
Programs at workplaces to lose weight, quit smoking or to increase the availability of vegetables at work canteens
TV series were broadcast where a group of people volunteered to make healthy lifestyle changes with the help of experts
Diet• The industry focused on the development of
low fat/salt dairy and meat products
• Close collaboration with vegetable oil product manufacturers to produce healthier spreads
• A project that encouraged people to grow berries
What happened?• Finland has reduced the number of heart
attacks by 75% since the early 1970s
• Many still die for cardiovascular diseases compared to some other countries, but results have still been tremendous and this is clearly due to the reduction in risk factors
• Published in 1972• 4 steps: approach,
weight loss, pre-maintenance and definitive maintenance
• Carbohydrate intake is reduced to 20 g per day and subsequently increased
• Published in a book in 1995
• 40% energy from carbohydrates, 30% from protein, 30% from fat
• It is supposed to improve the plasma lipid values
• Attack (3-10 days): protein predominate (eggs, fish, meat and dairy products low in fat), fruit and vegetables banned
• Cruise (one week for each kg to lose): in addition vegetables low in sugar.
• Consolidation (10 days for every kg of weight lost) reappear carbohydrates, but the regime is still not optimal for the body
Low carb/High fat (LCHF)• Up to 70% of energy from
fat• High intakes of animal and
vegetable fat products • High intakes of vegetables• Small intakes of legumes,
fruit, nuts• No cereal grains, potatoes
and no sweet products
