Long chain polyunsaturated fatty acids (LC-PUFA) and perinatal development

Area of Science:

• Nutrition Science
• Maternal and Child Health
• Biochemistry

Background:

• Long chain polyunsaturated fatty acids (LC-PUFA) play a crucial role in maternal and child health.
• Current knowledge on LC-PUFA status and functional outcomes is based on a review of published randomized trials.
• Investigator consensus was reached through a workshop focusing on LC-PUFA in maternal and child health.

Purpose of the Study:

• To summarize current knowledge on LC-PUFA in maternal and child health.
• To provide recommendations for dietary practices related to LC-PUFA intake.
• To establish guidelines for LC-PUFA content in infant formulas.

Main Methods:

• Review of full or abstract published randomized trials on LC-PUFA.
• Consensus development among investigators with expertise in LC-PUFA research.
• Synthesis of existing data to inform recommendations.

Main Results:

• Breastfeeding is recommended as the primary feeding method for healthy infants due to its LC-PUFA content.
• Specific minimum percentages of docosahexaenoic acid (DHA) and arachidonic acid (AA) are recommended for term and preterm infant formulas.
• Optimal LC-PUFA intakes for pregnant/lactating women and higher levels for infants require further investigation.

Conclusions:

• Healthy infants benefit from breastfeeding for LC-PUFA supply.
• Term infant formulas should contain at least 0.2% DHA and 0.35% AA.
• Preterm infant formulas require higher levels (0.35% DHA, 0.4% AA), and pregnant/lactating women should consider DHA-rich foods.
