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 Body01:31

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...
Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
Environmental Influences on Intelligence01:29

Environmental Influences on Intelligence

Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children from...
Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Area of Science:

  • Nutrition Science
  • Maternal Health
  • Dietary Supplements

Background:

  • Most pregnant women have inadequate omega-3 fatty acid intake.
  • Omega-3 fatty acids are crucial for preventing preterm birth.
  • New guidelines advocate for increased omega-3 intake during pregnancy.

Purpose of the Study:

  • To systematically document omega-3 levels in US and Canadian prenatal supplements.
  • To compare these documented levels with recommended pregnancy intakes.

Main Methods:

  • Utilized the Dietary Supplement Label Database (50 products) and Licensed Natural Health Products Database (18 products).
  • Calculated mean omega-3 levels and the proportion of products meeting recommendations.

Main Results:

  • Average omega-3 levels were 368±33 mg (US) and 404±72 mg (Canada).
  • 70% (US) and 61% (Canada) of products met sufficient intake recommendations.
  • 16% (US) and 28% (Canada) met insufficient intake recommendations.

Conclusions:

  • Commercial prenatal supplements exhibit diverse omega-3 fatty acid content.
  • Supplement levels may not consistently align with recommended intake levels for pregnant women.
