Omega-3

The omega-3s are a type of polyunsaturated fatty acid whose first double bond - C=C is on the third carbon atom (starting from the side opposite the acid group).

The precursor of the omega-3s isα- linolenic acid, so other omega-3s can be produced from this fatty acid.

Linolenic α- acid is essential to our diet as the body cannot produce it. This omega-3 is found in oily fish, algae and in vegetable oils such as walnut oil, linseed oil and rapeseed oil.

The omega-3 are necessary for the correct functioning of the brain as they are involved in cell formation. They are also believed to be involved in reducing the risks of cardiovascular accidents.

Our body needs approximately 1 to 2 grams of omega -3 each day. On the other hand, excessive consumption is also harmful with an increase in bad cholesterol, fall in blood glucose and fluidification of the blood.

According to Afssa recommendations, omega-3s should be 1/5 of our omega-6 consumption although in general the ratio is far lower.
