Food Fats against Depression

25.02.2004


Depression is the most prevalent psychiatric disease. The number of new cases rises and the disease manifests itself at an earlier age.



Depression is lower in populations with higher fish consumption. This leads to the question whether there might be something in fish that prevents depression or more general that is required for proper functioning of the brain.

Fats are major structural components of brain tissue. These fats are special in that they contain DHA. DHA is a fatty acid that can be made in the body only in limited quantities and only if special conditions are met. These conditions depend amongst others on the type of diet. A Western type of diet does not favour the formation of DHA. So it was considered possible that intake of preformed DHA is required for proper functioning of the brain. This brings us back to the association between fish consumption and depression: fish is main source of DHA and other ’higher omega-3 fatty acids’ in the diet.


Instead of estimating fish intake, higher omega-3 fatty acids can be measured in blood. This is what was done at Ghent University. In a first type of study (’case-control study’) it was found that patients with depression have lower levels of higher omega-3 fatty acids than patients without depression. In a second type of study (’follow-up study’) individuals with low and with normal levels of higher omega-3 fatty acids were followed up and the numbers of new cases of depression were measured. The study group consisted of women whose blood was drawn just after delivery. It was found that when EPA, one of the higher omega-3 fish fatty acids was lower, the probability to develop a postpartum depression was higher. We could further demonstrate that relatives of patients with depression also had reduced levels of higher omega-3 fatty acids pointing to a genetic predisposition.

The finding of reduced EPA in maternal blood at delivery was associated with more postpartum depression suggests that the previously found association between high fish consumption and low rate of depression was not due to DHA as first thought but to EPA. Indeed research groups in the UK and in Israel recently reported that beneficial results were obtained when patients with depression were supplemented with EPA but not with DHA.

Im Focus: Strathclyde-led research develops world's highest gain high-power laser amplifier

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.

The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
