Fish is loaded with important nutrients, such as
protein and vitamin D. It is also the world's best source of omega-3
fatty acids, which are incredibly important for
your body and brain
. Below are the health benefits of eating fish...
1. Fish Help Prevent Asthma in Children
Asthma is a common disease that is characterized by chronic inflammation in the airways. Unfortunately, rates of asthma have increased dramatically over the past few decades. Studies show that regular fish consumption is linked to a 24% lower risk of asthma in children, but no significant effect has been found in adults. BOTTOM LINE: Some studies show that children who eat more fish have a lower risk of developing asthma.
2. Fish May Protect Your Vision in Old Age
A disease called macular degeneration is a leading cause of vision impairment and blindness, and mostly affects older individuals. There is some evidence that fish and omega-3 fatty acids may provide protection against this disease. In one study, regular consumption of fish was linked to a 42% lower risk of macular degeneration in women. Another study found that eating fatty fish once per week was linked to a 53% decreased risk of neovascular ("wet") macular degeneration. BOTTOM LINE: People who eat more fish have a much lower risk of developing macular degeneration, a leading cause of vision impairment and blindness.
3. Fish is High in Important Nutrients
That Most
People Don't Get Enough of
Generally speaking, all types of fish are good
for you.
They are high in many nutrients that most
people aren't getting enough of.
This includes high-quality protein, iodine and
various vitamins and minerals.
However, some fish are better than others, and
the fatty types of fish is said to be the
healthiest .
That's because fatty fish (like salmon, trout,
sardines, tuna and mackerel) are higher in fat-
based nutrients.
This includes the fat-soluble vitamin D, a
nutrient that most people are deficient in. It
functions like a steroid hormone in the body.
Fatty fish are also much higher in omega-3
fatty acids. These fatty acids are crucial for
your body and brain to function optimally, and
are strongly linked to reduced risk of many
diseases.
To meet your omega-3 requirements, eating
fatty fish at least once or twice a week is
recommended.
BOTTOM LINE:
Fish is high in many important nutrients,
including high-quality protein, iodine and various
vitamins and minerals. Fatty types of fish are
also high in omega-3 fatty acids and vitamin D.
4. Fish Lower Your Risk of Heart Attacks
and Strokes
Heart attacks and strokes are the two most
common causes of premature death in the
world.
Fish is generally considered to be among the
best foods you can eat for a healthy heart.
Not surprisingly, many large observational
studies have shown that people who eat fish
regularly seem to have a lower risk of heart
attacks, strokes and death from heart disease.
In one study of more than 40,000 male health
professionals in the US, those who regularly ate
1 or more servings of fish per week had a 15%
lower risk of heart disease.
Researchers believe that the fatty types of fish
are even more beneficial for heart health,
because of their high amount of omega-3 fatty
acids.
BOTTOM LINE:
Eating at least one serving of fish per week has
been linked to reduced risk of heart attacks and
strokes, two of the world's biggest killers.
5. Fish Contains Nutrients That Are Crucial
During Development
Omega-3 fatty acids are absolutely essential for
growth and development.
The omega-3 fatty acid docosahexaenoic acid
(DHA) is especially important, because it
accumulates in the developing brain and eye.
For this reason, it is often recommended that
expecting and nursing mothers make sure to
eat enough omega-3 fatty acids.
However, there is one caveat with
recommending fish to expecting mothers. Some
fish is high in mercury, which ironically is linked
to brain developmental problems .
For this reason, pregnant women should only
eat fish that are low in the food chain (salmon,
sardines, trout, etc), and no more than 12
ounces (340 grams) per week.
Pregnant women should also avoid raw and
uncooked fish (including sushi), because it may
contain microorganisms that can harm the
fetus.
BOTTOM LINE:
Fish is high in omega-3 fatty acids, which is
essential for development of the brain and
eyes. It is recommended that expecting and
nursing mothers make sure to eat enough
omega-3s.
6. Fish May Increase Grey Matter in the Brain
and Protect it From Age-Related Deterioration
One of the consequences of ageing is that
brain function often deteriorates (referred to as
age-related cognitive decline).
This is normal in many cases, but then there
are also serious neurodegenerative diseases
like Alzheimer's disease.
Interestingly, many observational studies have
shown that people who eat more fish have
slower rates of cognitive decline.
One mechanism could be related to grey matter
in the brain. Grey matter is the major functional
tissue in your brain, containing the neurons that
process information, store memories and make
you human.
Studies have shown that people who eat fish
every week have more grey matter in the
centers of the brain that regulate emotion and
memory.
BOTTOM LINE:
Fish consumption is linked to reduced decline in
brain function in old age. People who eat fish
regularly also have more grey matter in the
brain centers that control memory and emotion.
7. Fish May Help Prevent and Treat Depression
Making You a Happier Person
Depression is a serious and incredibly common
mental disorder.
It is characterized by low mood, sadness,
decreased energy and loss of interest in life
and activities.
Although it isn't talked about nearly as much as
heart disease or obesity, depression is currently
one of the world's biggest health problems.
Studies have found that people who eat fish
regularly are much less likely to become
depressed.
Numerous controlled trials have also found that
omega-3 fatty acids are beneficial against
depression, and significantly increase the
effectiveness of antidepressant medications.
What this means is that fish can quite literally
make you a happier person and improve your
quality of life.
Fish and omega-3 fatty acids may also help
with other mental disorders, such as bipolar
disorder.
BOTTOM LINE:
Omega-3 fatty acids can be beneficial against
depression, both on their own and when taken
with antidepressant medications.
8. Fish is The Only Good Dietary Source of
Vitamin D
Vitamin D has received a lot of mainstream
attention in recent years.
This important vitamin actually functions like a
steroid hormone in the body, and a whopping
41.6% of the US population is deficient in it.
Fish and fish products are the best dietary
sources of vitamin D, by far. Fatty fish like
salmon and herring contain the highest
amounts.
A single 4 ounce (113 gram) serving of cooked
salmon contains around 100% of the
recommended intake of vitamin D.
Fish oils, such as cod liver oil, are also
very high in vitamin D, providing more than
200% of the recommended intake in a single
tablespoon.
If you don't get much sun and don't eat fatty
fish regularly, then you may want to consider
taking a vitamin D supplement .
BOTTOM LINE:
Fatty fish is an excellent source of vitamin D,
an important nutrient that over 40% of people
may be deficient in.
9. Fish Consumption is Linked to Reduced Risk
of Autoimmune Diseases
Including Type 1
Diabetes
Autoimmune disease occurs when the immune
system mistakenly attacks and destroys healthy
body tissues.
A key example is type 1 diabetes, which
involves the immune system attacking the
insulin-producing cells in the pancreas.
Several studies have found that omega-3 or fish
oil consumption is linked to reduced risk of type
1 diabetes in children, as well as a form of
autoimmune diabetes in adults.
The results are preliminary, but researchers
believe that this may be caused by the omega-3
fatty acids and vitamin D in fish and fish oils.
Some believe that fish consumption may also
lower the risk of rheumatoid arthritis and
multiple sclerosis, but the current evidence is
weak at best.
BOTTOM LINE:
Eating fish has been linked to reduced risk of
type 1 diabetes and several other autoimmune
diseases.
10. Fish Improve Sleep Quality
Sleep disorders have become incredibly
common worldwide.
There are many different reasons for this (such
as increased exposure to blue light), but some
researchers believe that vitamin D deficiency
can also play a role.
In a 6-month study of 95 middle-aged men, a
meal with salmon three times per week led to
improvements in both sleep and daily
functioning.
The researchers speculated that this was
caused by the vitamin D in the salmon.
BOTTOM LINE:
There is preliminary evidence that eating fatty
fish like salmon may lead to improved sleep.
