Role of Fish in Human Health

Fish play an important role in human health and nutrition in many parts of the world. In some Asian countries, people get as much as 75% of their daily protein from fish, which provides essential macronutrients and micronutrients. Micronutrient deficiencies like vitamin A, iron and iodine are a major public health problem in many countries, especially in Africa. Eating fish delivers important health benefits like omega-3 fatty acids which reduce heart disease risk, and vitamins and minerals like vitamin A for eye health, vitamin D for bone health, iodine for thyroid and brain development, and selenium as an antioxidant. Overall, regular fish consumption provides key nutrients and supports growth, health, and reduces disease and

• Vital  contribution  to  the  survival
 and  health
• In  some  of  Asia’s  poorest
 countries  (Banglades,
 Cambodia)  people  derive  as
 much  as  75%  of  their  daily
 protein  from  fish.   
•  “rich  food  for  poor  people”  
•  provides  essential  nourishment,  
macronutients and
micronutrients.  

• Malnutrition  is  still  a  problem  in  many
 countries   particularly  in  Africa.
 

• Micronutrient  deficiencies  of


  vitamin  A,  iron  and  iodine  are
  also  of  public  health  concern  in
  the  whole  African  region.
 

• Their  consequences  include  nutritional


 blindness,  poor  learning  capabilities,

poor  growth  and  increased  morbidity  

and  mortality  rates.

What are the health benefits of
fish?
1. Long-chain polyunsaturated fatty acids (PUFA)

• eicosapentaenoic acid (EPA) and


docosahexaenoic acid (DHA).
• present in both wild and farmed fish which
are found in abundance in the flesh of
oil-rich fish but they are also present in
lean fish.

The benifit of PUFA


• coronary heart disease.
• arthritis
• Alzheimer's disease
• some types of cancer and asthma
 2. Proteins

• The protein content in fish varies between


15 and 23%.
•
• The amount of connective tissue in fish
muscle is quite low and softens and
dissolves more readily when heated
compared to the connective tissue of land
animals.
•
• The connective tissue is easily broken down
by digestive enzymes making it very easy
for the body to digest.
 3. Vitamin A

• easily absorbed by the body.


• important in the eye for transmission
of light stimuli to the brain.
• It promotes growth and health of all
cells and is particularly important for
endothelial cells.

 4. Vitamin D

• needed for healthy bones


• helps to absorb calcium in the body.
 5. Iodine

• Fish contains more iodine than any other


food in a normal diet.

• Important for hormone development.


• A person who doesn't have enough


 iodine in his diet may develop an
 enlarged thyroid gland (goitre) or
 other iodine deficiency disorders.
•
•
6. Selenium

• The amount of selenium in fish


between 0.02 and 0.06mg per
100g fish flesh.
• Incorporated into a number of
enzymes in
 the body, such as glutathione
peroxidase.
• Protecting cell membrane from
damage
 by free radicals, which are linked
