What makes essential fatty acids amino acids different from ones that arent essential?
Svetlanka [38]

Answer:

\rB. nutrients that are essential cannot be made by the body, so they must be obtained from food.

Explanation:

If we look at the definition of essential fatty acids, it clearly states that these are fats which human body cannot prepare but are essential for proper functioning of body. Since body cannot synthesize them on their own, therefore we must obtain them through a diet rich in them. Two main essential fatty acids are:

  • Alpha-linolenic acid (omega-3)
  • linoleic acid (omega-6)

They play essential functions in body sucg as :

Production of hormones

Better adrenal and thyroid activity

Regulation of inflammatory and immune responses, function and development of brain.

Supporting the development of healthy skin and hair.

Option B is the best option.

Hope it helps!

Thank you
