Questão 28 - FITS 1° Dia 2018/2

TEXTO:

  We should eat at least two portions of fish, one
oily, a week according to the Department of Health
guidelines first issued in 1994. This was based on a
review of scientific evidence that related fish
[5] consumption inversely to coronary heart disease.
  The focus on oily fish and omega 3s is thought to
date back to the Seventies when researchers observed
that Inuit and Eskimo populations ate a lot of fish and
also had among the lowest rates of heart attacks, says
[10] Professor Sanders. The theory was that diets high in
omega 3 could block the effects of thromboxane, a
hormone in the blood, reducing the risk of clots. The
Inuits and Eskimos were also found to get a lot of
nosebleeds, suggesting their blood clotted less readily.
[15]   No studies have proven clearly that we need one
portion of oily fish a week. One of the few studies to do
so, the DART study in 1989, concluded that two or three
portions of fatty fish a week may reduce mortality in
men after a heart attack. But when they tried to test
[20] this finding in a larger study, it couldn’t be replicated.
“Eating oily fish once a week is associated with a lower
risk of cardiovascular disease, but it is difficult to
attribute this to the relatively small amounts of omega
3 provided by a single serving,” says Professor Sanders.
[25]   And a Cochrane Review in 2004 that looked at
heart benefits concluded: “It is not clear that dietary or
supplemental omega 3 alter total mortality, combined
cardiovascular events or cancers in people with, or at
high risk of, cardiovascular disease or in the general
[30] population.”
