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.

Alpha-Linolenic Acid Deficiency

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.

Iron Deficiency

ferritinWhat Is Iron?

[dropcap]I[/dropcap]ron is an essential mineral that is required for normal body function.

Almost two-thirds of iron in the body is found in hemoglobin, the protein in red blood cells that carries oxygen to tissues. Smaller amounts of iron are found in myoglobin, a protein that helps supply oxygen to muscle, and in enzymes that assist biochemical reactions.

Iron is also found in proteins that store iron for future needs and that transport iron in blood.

Q: How are iron stores regulated?

A:Iron stores are regulated by intestinal iron absorption.1That is, whenever iron is needed, more iron is absorbed than when iron is sufficient. This mechanism prevents excess iron in the body which is harmful.

In the brain, iron is necessary to ensure oxygenation and to produce energy in the cerebral parenchyma (via cytochrome oxid. ase), and for the synthesis of neurotransmitters and myelin.

Iron concentrations in the umbilical artery are critical during the development of the fetus, and in relation with the IQ in the child.2
