Foods that should be avoided during pregnancy stages

Mothers need to be aware of their nutrition during pregnancy stages and to stay away from some foods.

Paying attention to nutrition during pregnancy makes a great contribution to a healthy pregnancy. For this, some foods should be removed from the diet and some of them should be limited.

High mercury-containing fish:

Mercury is a highly toxic element and is found in high amounts in polluted seas. High levels of mercury ingestion cause toxic effects for the nervous system, the immune system and the kidneys.

Although it is more common in sea creatures living in polluted seas, large fish living in oceans also contain high amounts of mercury. In particular, fish, such as tuna, sword fishs and sharks, contain high mercury and it is recommended for pregnant women not to consume more than 1-2 portions a month.

It should be noted that only some of the fish contain high amounts of mercury. However, the consumption of fish during pregnancy stages should be 2-3 times per week because of the Omega-3 fatty acids in the fish in terms of the health of the baby in the womb.

Undercooked or raw meat

Consumption of undercooked or raw meat may cause various bacterial and parasitic infections. These can affect the baby’s health in the womb and lead to stillbirth or permanent neurological diseases.

While some bacteria are found on the outer surface of the meat, some can enter the muscle fibers. For this reason, red meat and poultry meat should be consumed as fully cooked.

Raw eggs

Raw eggs can carry an infection called salmonella. People infected with Salmonella may experience diarrhea, nausea, vomiting, fever and stomach cramps.

A mother who has salmonella may experience uterine contractions, and an increase in the risk of premature birth or stillbirth. Pregnant women should always consume eggs as cooked and pasteurized.


Caffeine is mainly found in coffee and tea. Daily caffeine consumption of pregnant women should not exceed 200mg. This amount is equivalent to 2-3 cups of coffee.

Caffeine is absorbed very quickly to the placenta. High caffeine intake during pregnancy stages may slow fetal development, cause low birth weight. You can learn more about this in our article named: Caffeine Intake During Pregnancy.


Pregnant women should not take alcohol because it increase the risk of miscarriage and stillbirth. Even a small amount of alcohol can adversely affect the baby’s brain development.
