In research that literally offers food for thought, scientists have
found that omega-3 fatty acids and uridine -- a natural substance found
in foods -- work as well as antidepressants in preventing signs of
depression.
The rat experiments used a well-established animal model of depression,
according to the researchers from Harvard-affiliated McLean Hospital in
Belmont, Mass.
The rats were placed in a tank of water, where they had no choice but
to swim. After a while, the rats realized swimming was futile, so they
simply began to float, a sign of surrender to depression. Given an
antidepressant drug, however, they started swimming again, the
researchers said.
But combined doses of omega-3 fatty acids and uridine were as effective
as three different antidepressants in prompting the rats to start
swimming again, said study author William Carlezon, director of
McLean's Behavioral Genetics Laboratory.
"We had given these two components [omega-3 fatty acids and uridine]
separately," Carlezon said. "As it became clear that each treatment in
its own way was having an effect, we came up with the idea of giving
them together to see if there would be a synergistic effect, because
they act on the same system."
The drugs and the dietary components used in the study probably act on
mitochondria in brain cells, he said. "Mitochondria produce energy for
brain cells," Carlezon explained. "Imagine what happens if your brain
does not have enough energy. Basically, we were giving the brain more
fuel on which to run."
The findings appear in the Feb. 15 issue of Biological Psychiatry.
Omega-3 fatty acids are well-known ingredients in many fish, and are
most abundant in oily species such as salmon and tuna. Cardiologists
recommend a diet rich in oily fish because omega-3 fatty acids are good
for the circulatory system. And what's good for the heart is also good
for the brain, said Dr. Bruce Cohen, president and
psychiatrist-in-chief at McLean Hospital.
"If you study people around the world and take people of similar
background, the group eating more fish has a lower rate of heart
disease and depressive illnesses," Cohen said.
Omega-3 fatty acids are best obtained by eating fish rather than in
dietary supplements, he said. "In fish, they are fresh and in the form
you need," Cohen said.
Uridine is a different matter. It's not found in high levels in any
particular food, Carlezon said. It is an important element in mother's
milk, and baby formula is enriched with uridine because it is essential
for early nerve growth, he said.
There are no uridine supplements now on the market, but there might be
a case for them, Carlezon said. More studies are needed to see whether
uridine in the diet affects mental capacity and learning, he added.
There are growing indications that mitochondria are involved in
psychiatric conditions other than depression, Carlezon said. McLean
researchers have found major alterations in the genes for mitochondria
in people with bipolar disorder, a condition that includes cycles of
depression.
