EPA (Eicosapentaenoic Acid) Deficiency

Macherel…EPA Rich!

What Is EPA?

[dropcap]E[/dropcap]PA (eicosapentaenoic acid) is an essential omega-3 fatty acid that is crucial for fetal brain and retina development and the child’s subsequent neurodevelopment among very many other activities in people of all ages.

Omega-3 fatty acids  are polyunsaturated long chain fatty acids which must be obtained from animal foods since they do not occur in plants.

In all ages, EPA is essential for normal brain function.

Q: Why is EPA essential to the way the brain works?

A: EPA helps nerve cells in the brain to communicate with each other.

In pregnancy, EPA may also play a role in determining the length of gestation and in preventing perinatal depression in the mother.1 and is essential for normal growth in children.

EPA is important building material for the eicosanoids, a large group of highly bioactive hormone-like substances including prostaglandins, leukotrienes, and thromboxanes that are involved in blood clotting, inflammation, and vasoconstriction. Its many important functions are described below.

What Is Alpha-Linolenic Acid?

[dropcap]A[/dropcap]lpha-linolenic acid is an essential (need/can’t make) polyunsaturated omega-3 fatty acid that must be obtained in the diet. Alpha-linolenic acid is found in plant sources only.

Alpha-linolenic acid is required for normal brain function and nervous system health. It is an important building material for the eicosanoids.

Q: What are eicosanoids?

A: Eicosanoids are a large group of highly bioactive hormone-like substances including prostaglandins, leukotrienes, and thromboxanes that are involved in blood clotting, inflammation, and vasoconstriction (constriction of blood vessels).

Alpha-linolenic acid is a “parent” fatty acid because if sufficient amounts are present in the body, it can be used to produce both eicosapentanoic acid (EPA) and docosahexaenoic acid (DHA), two other critical omega-3 fatty acids.1 However, this conversion is limited. In healthy individuals, the conversion rate of ALA to EPA is less than 5 to 10% and ALA to DHA is only 2 to 5%.

Additionally, a deficient level of the mineral selenium can interfere with the conversion of alpha-linolenic acid into EPA and DHA. Also, folic acid supplement has been shown to increase omega-3 status and, conversely, to decrease omega-3 when folic acid is in deficient in animal models.

Linoleic Acid (LA) Deficiency

nutsWhat Is Linoleic Acid?

[dropcap]L[/dropcap]inoleic acid is an essential omega-6 fatty acid that comes from plant sources. Essential means the body must have it to maintain health and life sustaining functions. Omega-6 fatty acids are polyunsaturated.

Among its many vital roles in the body, linoleic acid composition of intestinal membranes is important for epithelial cell function and disturbances may contribute to the pathophysiology of celiac disease.1

Q: What are epithelial cells?

A: Epithelial cells make up the surface mucosa of the digestive tract and also the respiratory tract, urinary tract and genital tract.

Linoleic acid is an important building material for the eicosanoids, a large group of highly bioactive hormone-like substances including prostaglandins, leukotrienes, and thromboxanes that are involved in blood clotting, inflammation, and vasoconstriction.2
