Insights

Docosahexaenoic acid (DHA) supplementation is safe for all infants. While developmental benefits are not consistently seen in term infants, preterm infants show improved outcomes due to higher DHA needs during critical growth periods.

Area of Science:

  • Nutritional Science
  • Developmental Pediatrics
  • Maternal-Fetal Medicine

Background:

  • Docosahexaenoic acid (DHA), an n-3 long-chain polyunsaturated fatty acid (LCPUFA), is crucial for infant growth and development.
  • Extensive research, including numerous randomized controlled trials (RCTs), has evaluated DHA supplementation in infant formulas and during pregnancy/lactation.

Purpose of the Study:

  • To review the existing literature on the effects of DHA supplementation on infant growth and development.
  • To identify specific infant populations that may benefit most from DHA supplementation.
  • To highlight emerging research directions in optimizing DHA supplementation strategies.

Main Methods:

  • Systematic review of published randomized controlled trials (RCTs) up to 2009.
  • Analysis of studies involving preterm infants, term infants, and supplementation during pregnancy/lactation.
  • Synthesis of findings regarding safety and developmental outcomes.

Main Results:

  • Dietary LCPUFA supplementation, including DHA, has demonstrated no harm in both preterm and term infants.
  • Developmental benefits from DHA supplementation are more consistently observed in preterm infants.
  • Preterm infants are at higher risk of DHA deficiency due to missed in-utero accumulation during the third trimester.

Conclusions:

  • DHA supplementation is safe for infants, regardless of gestational age.
  • Preterm infants represent a key population benefiting from DHA supplementation due to critical neurodevelopmental needs.
  • Future research should focus on determining optimal DHA dosage and timing for infants, particularly preterm infants.

Structure of Lipids03:38

Structure of Lipids

Lipids include a diverse group of compounds that are largely nonpolar in nature. This is because they are hydrocarbons that include mostly nonpolar carbon-carbon or carbon-hydrogen bonds. Non-polar molecules are hydrophobic (“water fearing”), or insoluble in water. Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of fats. Lipids also provide insulation from the environment for plants and animals. For example, they help keep aquatic birds and...

Lipid-derived Compounds in the Human Body

Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various  biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin, delayed...
Overview of Fatty Acid Metabolism01:28

Overview of Fatty Acid Metabolism

Lipids also are sources of energy that power cellular processes. Like carbohydrates, lipids are composed of carbon, hydrogen, and oxygen, but these atoms are arranged differently. Most lipids are nonpolar and hydrophobic. Major types include fats and oils, waxes, phospholipids, and steroids.
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...
Neuroplasticity01:01

Neuroplasticity

Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.
Lipids: Dietary Sources and Requirements01:18

Lipids: Dietary Sources and Requirements

Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ meats, shellfish,...
Lipids as Anchors01:32

Lipids as Anchors

In the plasma membrane, the lipids forming the bilayer can also act as an anchor to tether proteins to the membrane. The three main types of lipid anchors found in eukaryotes are – prenyl groups, fatty acyl groups, and glycosylphosphatidylinositol or GPI groups. Prenyl and fatty acyl groups act as anchors on the cytosolic surface of the membrane, whereas GPI anchors proteins on the extracellular side.
The carboxy-terminal of most of the prenylated proteins, such as Ras proteins, contains the...
