Linseed – a source of omega 3 for the human diet
• Simple• Traditional• Natural• Sustainable• Low cost
![Page 5: LINSEED A SOURCE OF OMEGA 3. Linseed Linseed and Flax are the same species 15,000 years of production Fibre - linen Seed - animal feed - oil (paints,](https://reader036.fdocuments.us/reader036/viewer/2022081515/551a667555034643688b4d08/html5/thumbnails/5.jpg)
The Problem• 60% of fat intake from animal products (meat,
milk, eggs)• Animal products have changed because animal
feeds have changed• Feeding less forage, more cereals & soya (high
n6, low n3)• So animal products higher n6, lower n3• So human diet higher n6, lower n3

A simple solution• Correct the imbalance in animal feeds• Include 5% LINSEED (best available, natural
source)• Increases n3 and improves n6:n3 ratio in milk,
meat, eggs• Increases n3 and improves n6:n3 ratio in our diet
and changes human lipid profile accordingly
• System now established in France

Crossover - double-blind
Milk cows Beef cows Pigs Table hens Laying hens Sheep
Milk, butter Beef Pork, pork products Chicken Eggs Lamb
75 healthy adults aged from 25 - 45 years, divided into 3 groups. Duration of 3 months, prohibition of any other animal product
Measurements
- On the products: Hedonic tests and sensory analyses, lipid profiles of products
- On the volunteers: 7 blood samples: Lipid profiles of serum and red corpuscles

ResultsProducts - More n3 (ALA, EPA, DHA)
- More conjugated linoleic acids (CLA) - n6:n3 ratio reduced (54% in butter,
60% in meat, 86% in eggs)Total diet - More ALA (1.65g vs 0.75g/day)
- More EPA/DHA- n6:n3 ratio reduced (7 vs 15)
People - In plasma ALA increased (0.93% vs 0.44%) and increased EPA/DHA/CLA- In red corpuscles increased EPA &
DHA

Sensory Characteristics• Numerous taste tests carried out
(triangular tests, preference tests, sensory analysis)
• Eggs and butter from linseed fed animals are preferred
• Meats are preferred and - have more flavour - are more tender - are more juicy

Confirmed in Scientific Studies
• Feeding linseed to animals produces milk, meat, eggs high in n3 (ALA, EPA, DHA)
• Eating these animal products
- increases our intake of n3 (ALA, EPA, DHA)
- improves the n6:n3 ratio of our diet
- improves our blood lipid profile• The foods taste better!

Commercial System• Developed and fine-tuned in France• Selected high ALA linseed varieties• Patented cooking process• 1.6 million tonnes of ‘linseed’ feed• Numerous food products
- many under BBC logo
- also own brands (Monoprix/Carrefour)
