Health Benefits of Eating Oysters During Pregnancy
Here is more detail on some of the key nutrients oysters provide during pregnancy and their health benefits:
Zinc
Oysters are the best dietary source of zinc. A 3 oz serving contains 32-40 mg of zinc, more than the 9-13 mg recommended daily during pregnancy. Zinc is critical for:
- Baby’s cell growth
- Brain development
- Immune function
- DNA synthesis
- Wound healing
- Growth throughout pregnancy
Oysters’ high zinc content helps prevent zinc deficiency and issues like birth defects, low birth weight, infections, preeclampsia, and prolonged labor.
Iron
Oysters provide iron to help prevent anemia, a common problem during pregnancy due to increased blood volume. Just 100g of oysters delivers 5mg of iron, about 28% of the daily requirement. Iron transports oxygen, aids baby’s growth, and prevents fatigue.
Omega-3 Fatty Acids
Omega-3s support the brain development of babies during pregnancy. Oysters have 280mg of omega-3s per 100g serving. They provide DHA, a specific omega-3 in high demand during pregnancy. Omega-3s may also prevent preterm births and postpartum depression.
Protein
Oysters contain 9g of complete protein per serving to support maternal and fetal tissue growth during pregnancy. Protein is also vital for increasing blood volume and fluid production.
Vitamin B12
Vitamin B12 helps form red blood cells and DNA. It supports nerve function and energy levels. Oysters provide 16mcg of B12 per serving, more than the 2.6 mcg recommended daily during pregnancy. Vitamin B12 prevents anemia and neurological issues.
Other Nutrients
Oysters also supply vitamin A for immune function, copper for forming red blood cells, calcium for bones and muscles, plus B vitamins for energy production. Their nutritional content optimizes maternal and baby health.
Potential Risks of Eating Raw Oysters When Pregnant
Eating raw oysters comes with the following risks during pregnancy:
Vibrio Infection
Vibrio bacteria can contaminate raw oysters living in warm coastal waters. It causes diarrhea, cramping, nausea, and vomiting. Vibrio vulnificus is a species that can enter the bloodstream and be life-threatening.
Norovirus
Raw oysters can harbor Norovirus which causes severe vomiting and diarrhea. Norovirus leads to dehydration and hospitalization in severe cases.
Hepatitis A
Raw oysters from contaminated waters may contain Hepatitis A virus. It can cause liver infection and damage. Hepatitis A also spreads person-to-person.
Listeriosis
Listeria bacteria is found in soil and water. Raw oysters can be contaminated with Listeria leading to fever, muscle aches, nausea, etc. Listeriosis can cause pregnancy complications like miscarriage, stillbirth, preterm labor.
Parasites
Raw oysters can carry parasites like Cryptosporidium (Crypto) and Giardia that infect the digestive system. They spread through contaminated food or water sources.
The vulnerable state of pregnancy raises risks of dehydration, hospitalization, and dangerous pregnancy complications from oyster-related infections.
When to Seek Medical Care After Eating Oysters
If you experience any of the following symptoms within 1-3 days after eating raw or undercooked oysters, seek prompt medical attention:
- Diarrhea lasting over 24 hours
- Bloody stool
- High fever (over 101°F)
- Vomiting preventing fluid intake
- Dark urine, little/no urination
- Severe abdominal pain
- Headache, muscle aches, fatigue
- Jaundice (yellow skin/eyes)
Notify your doctor immediately if you notice any possible signs of preterm labor after food poisoning, like:
- Contractions every 10 minutes or more
- Low, dull backache
- Pelvic pressure
- Cramping, belly tightening
- Fluid or bleeding from the vagina
Prompt treatment is needed to prevent severe dehydration and pregnancy complications. In severe cases, pregnant women may need IV fluids, antibiotics, or hospitalization to manage dehydration, infections, or early labor.
