Which foods are generally not recommended?

Here is a list of foods that are not recommended for breastfeeding mothers:

Seafood, fatty fish
Meat except for beef and chicken
Fatty dairy and sour milk products, cheese, pickles, marinades, canned food, sauces containing preservatives and spicy foods
Foods with artificial flavors and colorings
Smoked meat and sausages
Eggs
Wheat and oatmeal cereals
Nuts (especially peanuts), honey and caramel
Carbonated drinks and bright color juices
Chocolate and sweets
Strawberries, raspberries, and other red berries

So what are we left with? Only rice and green apples?

Forward-thinking doctors view the above list as too over-cautious. Doctors will indeed have an easier time diagnosing any medical issues with the baby if the mother has a strict diet, and the mother will feel better about it.

However, in reality, it is somewhat different. The restrictions can hurt the child's immune system since the immune system must learn how to cope with various allergens. Shying away from these foods will prevent the immune system from fully developing. At the same time, if a child eats, for example, oatmeal for the first time at the age of one, there is a chance that the immune system would react to it as to an 'alien' food and produce an allergic reaction.

Allergologists rely on this phenomenon to explain the allergic reaction to such food as pineapples and peaches compared to pears or plums. The more familiar the food is to the body, the lower are chances of having an allergic reaction.

What should you do?

The best solution is to have a balanced diet, introducing one new food per week. At the beginning of breastfeeding, it is recommended to eat cereals and simple products. If, after seven days, everything is fine, you can add yogurts and other milk products. You can also try fish (in general, breastfeeding mothers need fish because it is rich in phosphorus and Omega-3 polyunsaturated fatty acids). Keep an eye on the baby’s weight and skin. If the baby has rashes or red skin, the last introduced food should be eliminated from the diet.

If it causes the reaction, the condition should improve in 2–3 days. If this doesn’t happen, the issue could be something like a new washing detergent or skin cream.

Mothers shouldn't obsess over their diets, as doing so will negatively affect the quality of breast milk and women's health since their bodies are already exhausted by pregnancy, childbirth, breastfeeding, and stress. Mothers should always avoid carbonated drinks with artificial colors, foods with artificial flavors, and alcohol.

Which products usually cause allergies?

Although it does not always apply to everyone, babies often react poorly to citrus fruits, chocolate, nuts, honey, seafood, eggs, milk, and exotic fruits during breastfeeding. For this reason, you should be particularly cautious when introducing these foods to your diet.

What if the mother already has an allergy

Should mothers worry that their child may inherit their allergies?? Doctors are aware of such cases, but they do not have statistical proof that allergies are passed on to babies. Doctors do believe that babies should be given a small amount of food that causes an allergy to their mothers when they stop breastfeeding. The reason for this is an increased risk of immune response to the food.

Blood Transfusion for Premature Babies: A New Perspective

The largest randomized clinical trial on blood transfusion to premature babies was completed by Dr. Haresh Kirpalani of the University of Pennsylvania, Dr. Edward Bell of the University of Iowa, and colleagues from the Neonatal Research Network, including Dr. Rosemary Higgins of the George Mason University College of Health and Human Services. The study was published in the New England Journal of Medicine. To date, this is the most ambitious research in the world that examines blood transfusion in premature babies.
