Essential substances for the human diet
Omega-3 fatty acids are essential substances for the human diet. They are so essential to life and cannot be manufactured by the body itself. The substances improve the flow properties of the blood, inhibit blood clotting, blood pressure lowering, anti-inflammatory and affect the triglyceride metabolism. The German society for nutrition (DGE) therefore recommends that 0.5 per cent of the daily calories from Omega-3 fatty acids. That’s the equivalent of an adult is about the amount contained in a tablespoon of rapeseed oil. Some people resort to to Omega-3 fatty acid capsules. Whether taking the dietary Supplement, but it is really useful to explain consumer advocates.
Positive influence on health

Omega-3 fatty acids must be obtained from food
Omega-3 fatty acids can not be made by the body and must therefore be obtained from food.
Good Omega-3 suppliers, among other things, walnuts, green leafy vegetables (e.g. lettuce), some vegetable Oils (e.g., canola, walnut and Flaxseed) and Chia seeds.
But especially fish Omega-3 fatty acids. It is recommended here, in particular fat-rich sea fish such as mackerel, herring, tuna or salmon.
As a General rule, healthy people taking in a fully-fledged and well-balanced diet with enough Omega-3 fatty acids.
The consumer explained Central on your website, in the absence of fish, such as, for example, in the case of a vegan diet, hardly any eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
According to the experts, these can then be fed via fortified foods (e.g., enriched Oil, or Margarine) or food supplements (e.g. fish oil or marine microalgae).
However, such agents are also recommend in General?
Not for the treatment of diseases suitable
Dietary supplements Omega-3 fatty acids, such as fish oil or Flaxseed oil capsules, are often advertised in order to maintain a normal cholesterol and Triglyceride levels in the blood and a normal blood pressure.
They should also contribute to normal brain function, eyesight and heart function. These health claims are scientifically proven and allowed by law, explains the consumer.
However, the supplements must contain a minimum amount of these fatty acids. The permitted health claims, however, are often amplified and exaggerated.
For example, “contribute to a normal heart function in the case of” effective advertising “have protective properties for a healthy heart”.
In particular, the Internet, Omega-3 fatty acid products are advertised again and again, with not one of the acceptable statements such as “for protection against heart attack and stroke, help with Arthritis and joint pain” and “protection against breast cancer”.
However, Omega-3 fatty acid-containing dietary supplements are food and not for the treatment of diseases suitable.
No protection against heart attacks and strokes
A large study (meta-analysis) has shown, under the auspices of the University of Oxford that dietary supplements prevent, up to two grams of Omega-3 fatty acids per day, neither heart attack nor stroke. Whether higher-dose products, is still being researched.
In a further study, also from Oxford, it was examined whether taking capsules of fish oil (380 mg docosahexaenoic acid and 460 mg of eicosapentaenoic acid) diabetics against heart disease protects.
This specific target group were compared with subjects taking the placebo were given, no differences in the frequency of heart attacks, strokes, and cardiovascular-related deaths or cancers.
Some statements are prohibited by law
In the case of Omega-3 fatty acid products for children, infants or the Unborn child (products for Pregnant women), according to the consumer the following statements are scientifically documented:

The intake of DHA [200 mg daily in addition,] the mother contributes to normal development of the brain / the eyes in the foetus and breastfed infants.
However, these effects are obtained only when a certain amount of these fatty acids is taken daily. The preparations should therefore carry a corresponding note.
If in a product in addition to the Omega-3 fatty acid α-linolenic acid [0.2% of total energy daily] the Omega-6 fatty acid linoleic acid [from 1 % of total energy daily], may also be the following statement on the product:
α-linolenic acid and linoleic acid needed for healthy growth and healthy development in children.
Statements to the effect that Omega-3-fatty acids to calm, Composure, concentration, learning ability, thinking ability and intellectual development of children (from one to twelve years, in connection with ADHD) are prohibited by law.

Products with manufacturer’s recommended amount of up to five grams of EPA and DHA (in combination) and 1.8 grams of EPA (individually) per day for adults, according to the European food safety authority as safe for health.
A warning that the quantity of five grams daily will not be exceeded, in doses of two grams a day for food supplements and fortified foods required.

Furthermore, Nausea and vomiting may occur.
In people with Diabetes may be the blood sugar control more difficult and the immune system will be adversely affected, which may lead to an increased susceptibility to infections especially in the elderly.
