Essential substances for human nutrition, they are therefore vital and cannot be produced by the body itself. Omega-3 means that the last double bond in the polyunsaturated carbon chain of the fatty acid is present in the third-last C-C bond as seen from the carboxy end. Omega is the last letter of the Greek alphabet and denotes the end of the carbon chain furthest from the carboxy group.
Chia seeds have a high omega-3 fatty acid content
Omega-3 fatty acids are contained in algae, plants or fish as carboxylic acid esters or triglycerides.
of vegetable origin to a small extent into eicosapentaenoic acid, docosapentaenoic acid and docosahexaenoic acid. If, on the other hand, high amounts of omega-6 fatty acids were supplied, conversion rates dropped by 40-50%. For example, linseed oil has an omega-6 to omega-3 fatty acid ratio between 1:6 and 1:3 and is therefore significantly lower than 4:1.
However, the total amount of omega-3 fatty acids in butter is very low. Rapeseed oil is between 1:1 and 6:1 and thus does not yet exceed the 6:1 limit. The content of omega-3 fatty acids in linseed oil, butter and rapeseed oil is based entirely on α-linolenic acid. A study by the Royal Adelaide Hospital in Australia shows that α-linolenic acid-rich vegetable oil increases tissue EPA levels similar to supplementation with fish oils.
Vitamin and mineral deficiencies, stress and age can slow down conversion. On the other hand, vitamins B and C, magnesium and zinc can activate these enzymes. Fish oils contain EPA and DHA directly. Beef contains significantly fewer omega-3 fatty acids, both in the form of α-linolenic acid and as EPA and DHA.
DART and GISSI-P showed a reduction in overall mortality between 20 and 29 percent of sudden cardiac death of about 45 percent and cardiac events after administration of just under one gram EPA and DHA per day. DART-2 was collected so poorly that reliable conclusions could not be drawn. Traditionally, Japan consumes a lot of fish, including EPA and DHA, which results in high levels.
The placenta supplies the growing fetus with 50-60 mg docosahexaenoic acid per day. regulatory mechanisms in the placenta try to locate the fetus on an omega-3
