How to Know What Foods to Avoid During Pregnancy

It’s known that you should eat healthy food, consume useful vitamins and minerals if you want a healthy baby. But what precautions should you remember and what food is to be avoided during gestation?
The main rule you should follow is to consult your healthcare provider, because not every article about right nutrition suits every woman.
Seafood is thought to be a source of useful elements, it promotes brain development. But it’s better to evade eating much fish (some types of fish contain large amount of mercury which can lead to autism, for instance sword fish, tilefish, tuna). It’s safe to eat little portions of cod, catfish and salmon. Exclude oysters, clams and raw fish (which is one of the main ingredients for sushi), as far as it can turn out to be a source of parasite infection.
While cooking make sure food isn’t undercooked. It concerns meat, fish poultry and eggs (Raw food can be contaminated with salmonella). 
Forget about junk food. Take care about your and your baby’s health. Preserved food isn’t also recommended as far as it contains nitrates and other chemical substances which can do harm to a fetus.
Soft cheeses, pate and unpasteurized dairy products are dangerous for pregnant women, because it’s possible that they contain bacteria called “listeria” which can affect your baby development and even lead to a miscarriage.
What concerns caffeine, it’s often related with miscarriages, so neglect all product containing it.
Despite some herbs have positive influence on health; pregnancy is time to avoid some of them. Raspberry tea can cause some complications and it is better to be exchanged for chamomile or ginger tea.
Nuts are also should be avoided, otherwise it’s possible that your baby will suffer from allergy to nuts or asthma.
Fruits and vegetables should be thoroughly washed; otherwise chemicals used to fertilize the soil where they were grown can influence your future child.
There’s no necessity to say that alcohol, tobacco and drugs are strictly forbidden during pregnancy. Such substances can have a severe impact on your baby.
