Abstract
The last national study on individual food consumption confirmed that French consumers have a very low intake of omega 3 alpha-linolenic acid (ALA), as well as an inadequate balance between omega 6 and omega 3 fatty acids, that should be compensated with a more important intake in omega 3. Certain types of margarines and spreads offer the possibility to increase the intake in this nutriment, in particular margarines containing linseed oil. Their high content of ALA allows, on the basis of a daily consumption of 20 g, to counterbalance, partially or totally, the low intake in omega 3. However, these spreads require a quite particular attention in their development and their production, mostly because of the relative instability of the linseed oil in the oxidation process and the need to avoid developing of off tastes until the end of shelf life.
Highlights
Recommendations for French population on daily food intakes of fats, and especially of essential fatty acids like linolenic acid, have been first published in 2001 and have been revised in 2011 by ANSES (French Agency for Food, Environmental and Occupational Health & Safety)
Spreads and margarines are significant contributors to unsaturated fatty acids intake and improvement of these products: adding oils rich in omega 3 like linseed oil is in the nutritional interest for French population
The daily average intake in poly-unsaturated fatty acids omega 3 for French population is twice lower than the recommended contributions (Tab. 1) and in average, the lack in omega 3 (ALA) is about 1.2 g per day and adult
Summary
Recommendations for French population on daily food intakes of fats, and especially of essential fatty acids like linolenic acid (omega 3 ALA), have been first published in 2001 and have been revised in 2011 by ANSES (French Agency for Food, Environmental and Occupational Health & Safety). Recommended daily consumption of ALA for an adult was increased from 0.8% of total Energy intake to 1% (equivalent to 2.2 g per day for an adult with a 2000 kcal diet), due to positive observation regarding prevention of cardiovascular diseases, obesity and inflammatory disease. Spreads and margarines are significant contributors to unsaturated fatty acids intake and improvement of these products: adding oils rich in omega 3 like linseed oil is in the nutritional interest for French population
