*These substances are contained in coffee, tea, and cola-based drinks. And is that caffeine affects sleep and heart rate. On the other hand, if pregnancy is at risk, doctors advise completely avoiding coffee consumption.

*As for decaffeinated coffee, its consumption is authorized by experts, as long as it is done in moderation, no more than one cup a day.

*Decaffeinated coffee contains a small percentage of caffeine since no method used to date to extract caffeine from the beans has managed to eliminate it. So while regular coffee contains about 100 mg of caffeine, decaffeinated contains 2 mg.

*Alcoholic beverages are also prohibited during pregnancy since alcohol increases the risk of miscarriage, premature labor, and other complications in childbirth.

*In addition, alcohol hinders the absorption of folic acid and other B vitamins, so essential for the proper development of pregnancy.

2. Salmonellosis:

Salmonellosis is another of the main dangers of eating shellfish during pregnancy.

It is a disease caused by the ingestion of food with a bacterium called salmonella, which causes food poisoning, especially raw meat or fish.

If you decide to eat fish or shellfish at some point, you must check that the cooking is very careful and at high temperatures.

This is so, especially in the case of mussels, octopuses, clams, or shrimp.

And it is that, although they are delicious, they can contain dangerous microorganisms or pathogens.

3. Green potatoes:

Green potatoes should not be consumed either. And it is that this food contains a substance responsible for the poisoning, with symptoms such as gastroenteritis and headache.

4. Undercooked or raw meat

The meat is animal protein, but if you eat it raw you run the risk of contracting toxoplasmosis since the parasite that causes this disease appears in the meat of animals that eat grass.

This parasite remains in raw meat and does not disappear if the meat is undercooked. Toxoplasmosis is a disease that can go unnoticed if you contract it at any time in your life, but if you are pregnant it can cause malformations in the baby.

This is why it is very important to avoid eating raw or undercooked meats. Within this type of meat, there are sausages or cold cuts that are made with raw meat: these will also be prohibited during pregnancy.

Yes, you can include in your diet, however, steamed cold cuts, such as York ham or turkey. Therefore, some foods that are prohibited during pregnancy will be, for example, carpaccio, steak tartare, or Serrano ham.

5. Raw fish

Raw fish does not contain the toxoplasmosis parasite, but it may contain anisakid larvae. These worms do not directly affect the baby, but if the mother contracts them, she can become seriously ill and thus affect the health of the baby.

This means that one of the prohibited foods for pregnant women will be, for example, sushi. To avoid this, you must avoid eating raw fish, and if you want to eat it, you must freeze it for at least 48 hours, to ensure that the anisakis larvae die.

To avoid this disease, you should always cook the fish at a high temperature and check that it is well done, in addition to buying it without the guts or cleaning the fish as soon as possible.

6. Unpasteurized cheeses

When you want to eat cheese, you should always choose cheeses that are cured, pasteurized, and have a hard consistency.

If this bacteria is contracted it can be very serious for the baby and create many complications in the pregnancy. Better avoid them.

Likewise, it is necessary to rule out the consumption of tomatoes, which are rich in a toxic substance that disappears with maturation and can cause gastrointestinal disorders.

8. Raw eggs

When you have to eat eggs, you can do it, but always very well cooked. Raw eggs can contain salmonella, which can have serious consequences for both mom and baby. To be completely safe, avoid foods in which the egg is used raw, such as mayonnaise, or dishes such as tiramisu.

9. Salt

During pregnancy, experts also recommend moderating salt intake to avoid fluid retention. And it is that sodium facilitates fluid retention and causes an increase in blood volume that favors the state of hypertension and makes it difficult for the heart to work.

*In addition to reducing salt intake, you must also avoid eating those foods that contain it. Therefore, do not exaggerate with the consumption of preserves and you must always read the labels of processed foods, since many additives contain sodium, such as monosodium glutamate, nitrate, nitrite, citrate, or sodium sorbate.

*For the same reason, it is necessary to limit the consumption of salty cheeses, such as feta or some goat cheeses, and the use of condiments rich in sodium, such as concentrated bouillon cubes, soy sauce, ketchup, or mustard. Also avoid salty snacks, such as French fries or popcorn.

*To replace salt and that your meals have a more intense flavor, you can opt for aromatic herbs. Freeway to spices such as oregano, thyme, or rosemary.

10. Mozzarella cheese:

As we have said, soft cheeses, usually fresh or very smooth, are usually made with raw milk, in their traditional manufacture. 

*However, the popularization of these cheeses and their massive consumption, which has promoted the industrial production of these products, has meant that most of these cheeses are now made with pasteurized milk.

*Mozzarella-type cheese is a very good example. Although its traditional preparation uses raw buffalo milk, the industry and the internationalization of this popular food have promoted the use of pasteurized milk in products usually sold in supermarkets.

11. Liver

The liver is a food that contains a large amount of vitamin A and also concentrates in it all the chemical substances that the animal ingests. Vitamin A in large amounts can harm the baby and cause malformations in it, so you should avoid eating livers and pates, to ensure the health of the baby. It is important not to eat these foods, especially in the first trimester of pregnancy.
