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: Data storage using individual molecules

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.

Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: An energy-efficient way to stay warm: Sew high-tech heating patches to your clothes

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
