Wild berries in Finland
•Minimum yield is 100kg/person•Highest yield from lingonberry, crowberry, bilberry•About 20 different wild berries can be used in nutrition•Only 10 % of the total yield is picked

Berries in Finland
•Wild berry consumption is 8 kg/person/year•Highest commercial value: lingonberry, bilberry, raspberry, cloudberry, cranberry, sea-buckthorn and crowberry•Export products
• strengths: pure nature, nutritional content, possible health effects
•Also currants (not grown wild) commercially important

Nutrients in berries
Fibre promotes bowel function, prevents colon and rectum cancer,
stabilizes postprandial blood glucose levels, increases satiety, helps in controlling cholesterol levels
Vitamins C and EPhenolic compounds

Phenolics in berries
Phenolics often possess antioxidative activity Compounds responsible for the color Compounds of the chemical defense system

”Antioxidants”
Fats, proteins etc. may undergo oxidation in biological systems Phenolics in berries are antioxidants – are they active also in gastrointestinal tract or other parts in human body?

”Antioxidants”
Antioxidant may act as a pro-oxidant under certain unfavorable conditions
Potential health effects of berries exerted also – or even primarily – via other mechanisms (e.g. cellular and genetic effects)
For example, phenolics have been associated with the reduced risk of cardiovascular diseases and certain cancers

Health effects
Berries have been reported to balance postprandial blood sugar levels and insulin response
e.g. sea-buckthorn, berry mixtures Effects of fibre and phenolic compounds Contribute to reduced risk of cardiovascular
diesases and diabetes?

Affect liver function? Elevated ALAT is an indicator of fatty liver
disease and therefore, increased risk of diabetes
Health effects

Sea-buckthorn is implicated in the reduction of CRP value CRP is an indicator of inflammation Even a slight elevation in the CRP value seems to
indicate an increased risk of cardiovascular diseases
Sea-buckthorn oil may decrease the risk of blood clots and relieve dry eye symptoms
Blackcurrant seed oil may protect from athopy in infants
Health effects

Health effects
Cranberries may protect from urinary tract infections
The evidence is not very strong Lingonberry could challenge the cranberry (also regarding other health
promoting effects…)?
