Pregnancy FAQs #2 What Foods Should I Avoid During Pregnancy??”

Pregnancy is a time of great joy and anticipation — but also a time for increased care and caution, especially when it comes to what you eat. While most foods are safe when properly handled, certain items carry increased risks for the developing fetus and the expectant mother due to bacteria, toxins, or nutritional imbalances.

As a Gynaecologist, I often meet expectant mothers who are unsure of what’s safe and what’s best avoided. This article serves as a practical and evidence-based guide to foods you should avoid during pregnancy, along with safer alternatives.





1. Raw or Undercooked Meat

Raw or undercooked meat may harbor pathogens such as Listeria monocytogenes, Toxoplasma gondii, Salmonella, and E. coli. These can lead to severe foodborne illnesses, some of which cross the placental barrier and impact fetal development.

🔍 Risk: Miscarriage, stillbirth, preterm labor, neonatal infection
✅ Recommendation: Ensure all meat (including poultry and sausages) is fully cooked to a safe internal temperature (above 75°C), with no residual pink or blood.

2. Unpasteurized Dairy Products

Soft cheeses (e.g., brie, camembert, blue cheese) and unpasteurized milk can contain Listeria, a bacterium capable of causing life-threatening infections in pregnancy, even with mild or absent maternal symptoms.

🔍 Risk: Listeriosis — associated with miscarriage, stillbirth, and neonatal sepsis
✅ Recommendation: Choose only pasteurized dairy products. Hard cheeses (e.g., cheddar, parmesan) and pasteurized soft cheeses are generally safe.

3. Raw or Undercooked Eggs

Eggs that are raw or undercooked may carry Salmonella, which increases the risk of food poisoning, especially dangerous in pregnancy due to immunological changes.

🔍 Risk: Gastroenteritis, dehydration, intrauterine infection (in rare cases)
✅ Recommendation: Consume fully cooked eggs with firm yolks and whites. Avoid homemade preparations using raw eggs (e.g., mayonnaise, mousse, tiramisu).

4. High-Mercury Fish

Methylmercury, found in certain large predatory fish, is neurotoxic and can impair fetal brain development, particularly in the first trimester.

🔍 Risk: Cognitive delays, motor dysfunction, developmental impairment
❌ Avoid: Shark, swordfish, king mackerel, tilefish
✅ Safer Alternatives: Low-mercury options such as salmon, sardines, trout, and catfish (2–3 servings/week recommended for DHA benefits)

5. Raw Seafood and Shellfish

Sushi, sashimi, oysters, and other uncooked seafood pose a risk for parasitic and bacterial infections such as Listeria, Vibrio, and Anisakis.

🔍 Risk: Gastrointestinal illness, fetal infection, miscarriage
✅ Recommendation: Opt for thoroughly cooked seafood only. If consuming sushi, ensure it is made from cooked ingredients (e.g., tempura rolls).

6. Caffeine (in Excess)

Excessive caffeine intake has been linked to increased risks of miscarriage, fetal growth restriction, and low birth weight.

🔍 Risk: Delayed fetal development, increased risk of pregnancy loss
✅ Limit: Less than 200 mg per day (~1 regular cup of coffee). Monitor intake from coffee, tea, chocolate, colas, and energy drinks.

7. Alcohol

Alcohol consumption at any stage of pregnancy is contraindicated. No known "safe limit" exists, and exposure may result in Fetal Alcohol Spectrum Disorders (FASD) — affecting physical, behavioral, and intellectual development.

🔍 Risk: FASD, miscarriage, preterm birth, growth restriction
❌ Strictly avoid alcohol throughout pregnancy

8. Unwashed Produce

Fresh fruits and vegetables are vital, but if unwashed, they may be contaminated with Toxoplasma, pesticides, or other pathogens.

🔍 Risk: Toxoplasmosis — may lead to neurological or ocular fetal damage
✅ Recommendation: Rinse thoroughly under running water. Peel or cook when appropriate.

9. Processed and Packaged Foods

Highly processed foods are often laden with trans fats, excess sodium, and added sugars — all of which may contribute to gestational hypertension, gestational diabetes, and unhealthy weight gain.

🔍 Risk: Metabolic complications, increased risk of cesarean delivery
✅ Recommendation: Prioritize whole, nutrient-dense foods. Read labels carefully and limit packaged snacks, ready meals, and sugary beverages.

Your body is working round-the-clock to nurture new life. The food you eat directly affects your baby's growth and your own well-being. While you don’t have to follow a perfect diet, being mindful of high-risk foods and choosing safe alternatives can make a big difference.

If you’re ever unsure about what’s safe, always consult your doctor or a qualified nutritionist.

Menstrual Cycle & Health: 8 Important Signals Your Period Is Giving You

Your menstrual cycle is more than just a monthly bleed — it’s a regular biological signal that offers deep insight into your reproductive, hormonal, and overall health . Many women normalize discomfort, mood swings, or irregularities, but these symptoms could be your body’s way of asking for help. When your cycle is regular, it’s often a sign that your body is balanced and functioning well.

A disruption in any of these hormones can result in irregularities in the cycle — which often ...

Dr. Kavita Sharma’s Breastfeeding Guide: What Every New Mother Should Know

Image
  Bringing a baby into the world is a beautiful journey — but let’s be honest, it also comes with new responsibilities and challenges. Breastfeeding is one of the most important — yet most overwhelming — experiences for new moms. As a gynecologist, I’ve seen many mothers feel confused or unsure during the early days of nursing. That’s completely normal. Here’s my expert guidance to help you start breastfeeding with confidence, comfort, and care. 🍼 1. Start Early — Within the First Hour The first hour after birth is known as the “Golden Hour.” Your baby is alert and naturally ready to latch. Early skin-to-skin contact helps release oxytocin, boosts milk supply, and builds emotional bonding. 🌼 2. Colostrum Is Nature’s First Vaccine That thick, yellowish milk in the first few days? It’s called colostrum — and it’s packed with antibodies and nutrients. Even a few drops are powerful for your baby’s immunity. Don’t worry if it seems like “too little” — it’s exactly what your ...
