What We Eat in the First Months of Breastfeeding – Forbidden Foods and Recommended Diet

The nutritional intake during breastfeeding is a determining factor for both the mother’s health and the optimal development of the newborn, having a direct impact on the composition and quality of breast milk. After birth, the maternal body undergoes a series of complex physiological adaptations designed to support milk production and ensure the mother’s increased energy needs. Therefore, it is essential for the diet to be balanced, varied, and adapted to the specific nutritional needs of this period. What we eat in the first months of breastfeeding thus becomes an important question, considering that certain foods can stimulate milk production and contribute to the general health of the mother and baby.

Adequate intake of macronutrients and micronutrients is fundamental for maintaining the mother’s health and supporting optimal lactation. Quality proteins, essential fatty acids, vitamins, and minerals play a crucial role in the synthesis of bioactive components of breast milk. Proper hydration is also essential for maintaining adequate milk secretion, given that breast milk contains approximately 87% water.

In this article, we will analyze in detail the principles of healthy nutrition during breastfeeding, highlighting recommended foods to support lactation, those that require moderate consumption, and categories of products that should be avoided to prevent infant digestive discomfort or potential adverse reactions. We will also address the specific caloric and nutritional needs, the importance of supplementing certain micronutrients, and debunk common myths associated with nutrition during this crucial stage.

Maternal nutrition during breastfeeding plays an essential role in the composition and quality of breast milk, directly impacting the newborn’s neurological, immune, and bone development. Nutrients from the diet are transferred into breast milk, contributing to meeting the infant’s nutritional needs. Although there is no strict diet, it is essential that the diet is balanced, varied, and adapted to the increased metabolic demands of the maternal body.

To support optimal milk production and maintain the mother’s health, adequate intake of essential macronutrients and micronutrients is necessary. High-quality proteins, provided by foods such as lean meat, fish, dairy products, eggs, and legumes, are indispensable for the synthesis of enzymes and hormones involved in the lactation process. Complex carbohydrates, found in whole grains, vegetables, and fruits, provide the energy needed for milk production while maintaining stable glycemic balance. Healthy fats, especially omega-3 fatty acids, are essential for the development of the central nervous system and visual function of the infant, and it is recommended to include sources such as fatty fish (salmon, sardines), nuts, seeds, and extra virgin olive oil in the diet.

Essential micronutrients in breastfeeding

Among the micronutrients with a crucial role during breastfeeding, calcium is indispensable for the infant’s bone development, and its increased need can be met by consuming dairy products, almonds, and green vegetables. Iron is vital for preventing maternal anemia and supporting the baby’s hemoglobin production, being present in red meat, liver, spinach, and legumes. Folic acid contributes to cell division and nervous system development, and its intake can be optimized by consuming leafy green vegetables, citrus fruits, and fortified cereals. Vitamin D is essential for calcium metabolism and bone health, and moderate sun exposure and supplementation, if necessary, are recommended.

An important peculiarity of breast milk is the influence of maternal diet on its taste and composition. Certain strong-smelling foods, such as garlic, onions, or spices, can alter the taste of milk, and the baby’s reactions to these changes can vary. Also, the consumption of foods that cause intestinal gas in the mother, such as cabbage or legumes, can be monitored to observe any effects on the infant’s digestive comfort.

The importance of digestion and the microbiome

Healthy digestion is essential at this stage, as intensified metabolic processes require optimal absorption of essential nutrients for breast milk production. In this context, maintaining a balanced gut microbiome becomes a key factor for the mother’s general health and, consequently, for the nutritional quality of breast milk.

[cta_produs style=”style_1″ product=”127044″ image=”https://aronia-charlottenburg.com/wp-content/uploads/2025/03/Ce-trebuie-sa-mananci-cand-alaptezi_-Importanta-alimentatiei-in-timpul-alaptarii-Aronia-HERO-product.jpg”]

Furthermore, probiotics and prebiotics are important for supporting maternal digestive and immune function, having the ability to restore the balance of intestinal flora, improve nutrient absorption, and reduce digestive discomfort, such as bloating or constipation, commonly encountered postpartum. Administering a supplement of Probiotic-Prebiotic Capsules, with a broad spectrum of beneficial bacteria, can contribute to maintaining optimal intestinal transit and reducing the risk of intestinal dysbiosis, which could indirectly affect the infant’s well-being.

By supporting the maternal intestinal microbiota, probiotics can also have indirect benefits for the newborn, as certain beneficial bacteria and their metabolites can be transferred through breast milk, thus contributing to the maturation of the baby’s digestive and immune system. Moreover, the prebiotics in the composition of these capsules provide a nutritional substrate for the existing beneficial bacteria, thus enhancing the probiotic effects and maintaining long-term gastrointestinal health.

Therefore, adopting a balanced, diversified, and nutritionally adequate diet is essential for maintaining the mother’s optimal health and supporting quality lactation, thus ensuring the premises for the baby’s harmonious development.

Caloric and nutritional needs during breastfeeding

During breastfeeding, the maternal body’s energy needs increase significantly, estimated at an additional 300-500 kcal per day compared to the pre-pregnancy period. This additional intake should come from high-value nutritional food sources, avoiding ultra-processed products rich in refined sugars and trans fats, which can negatively influence maternal metabolism and breast milk composition.

Protein intake

Thus, the recommended daily protein intake for a breastfeeding mother is between 65 and 75 g, playing an essential role in the synthesis of structural and enzymatic components necessary for the infant’s growth and development. Optimal protein sources include lean meat (chicken, turkey, beef), fish rich in omega-3 fatty acids (salmon, sardines, mackerel), eggs, whole dairy products, and legumes. These foods provide essential amino acids necessary for protein synthesis and maintaining effective lactation.

Complex carbohydrates

Complex carbohydrates, such as whole grains (oats, quinoa, brown rice), vegetables, and fruits, are essential energy sources, contributing to maintaining stable blood sugar levels and providing necessary fiber for optimizing intestinal transit. During this period, it is recommended to avoid simple carbohydrates (sugary drinks, refined sweets) that can cause blood sugar fluctuations and negatively affect maternal hormonal balance.

The role of lipids

Lipids play a fundamental role in the development of the infant’s nervous system, especially omega-3 essential fatty acids (DHA and EPA), which are involved in brain and retina maturation. Regular consumption of fatty fish, nuts, flaxseeds, extra virgin olive oil, and avocado contributes to ensuring an optimal lipid profile for maternal health and the baby’s optimal development.

The importance of calcium

Calcium is an essential nutrient during this period, playing a crucial role in maintaining maternal bone density and the infant’s skeletal development. Pediatric specialists recommend a daily intake of at least 1000 mg of calcium, from whole dairy products, aged cheeses, yogurt, but also from plant-based sources such as almonds, tofu, or green leafy vegetables (spinach, kale). Calcium deficiencies during this stage can increase the risk of osteopenia and osteoporosis in mothers.

The role of iron

Last but not least, iron remains an essential element during the postpartum period, especially in cases of significant blood loss during childbirth. Insufficient intake can lead to iron-deficiency anemia, affecting the mother’s energy levels and the body’s ability to support optimal milk production. Sources rich in heme iron (lean red meat, organ meats, fish) and non-heme iron (legumes, fortified cereals, seeds) should be strategically included in the diet, preferably alongside foods rich in vitamin C to improve the absorption of this mineral.

Allowed and recommended foods when breastfeeding – Allowed vegetables and fruits during breastfeeding

For breastfeeding mothers, optimal intake of vitamins, minerals, and antioxidants is an essential paradigm for maintaining maternal health and supporting the infant’s harmonious development. A diversified diet, based on regular consumption of vegetables and fruits, ensures a constant source of essential micronutrients, contributing to metabolic balance and supporting the lactation process.

Green leafy vegetables, such as spinach, kale, and Brussels sprouts, are concentrated sources of iron, calcium, and folic acid, indispensable elements for preventing maternal anemia and for the infant’s neurological development. Due to their high vitamin K content, these vegetables support blood clotting and maintain the integrity of the vascular system. Consuming them raw or lightly steamed maximizes nutrient bioavailability, avoiding losses associated with prolonged heat treatment.

Berries, such as blueberries, blackberries, and raspberries, are rich in polyphenolic antioxidants and vitamin C, playing a crucial role in combating oxidative stress and supporting the immune system. The bioactive compounds in these fruits protect cellular structures against premature degradation and contribute to maintaining blood vessel elasticity, thus preventing the risk of systemic inflammation. Citrus fruits, due to their high concentration of ascorbic acid, stimulate the absorption of non-heme iron and support collagen synthesis, essential for postpartum tissue regeneration. However, moderate consumption is recommended, especially for infants prone to atopic dermatitis or gastrointestinal irritation.

Benefits of avocado in maternal diet during breastfeeding

Avocado is a particularly valuable food at this stage, due to its high content of monounsaturated fatty acids, fiber, and potassium. These healthy fats are essential for the baby’s nervous system development, support maternal cardiovascular function, and contribute to maintaining stable blood sugar levels. Potassium regulates muscle activity and blood pressure, reducing the risk of fatigue and electrolyte imbalances.

Bananas, besides being a quick source of energy due to their moderate absorption carbohydrate content, provide tryptophan, a precursor to serotonin, thus contributing to mood regulation and preventing episodes of postpartum exhaustion. Carrots, broccoli, and sweet potatoes are rich in beta-carotene, a precursor to vitamin A, fundamental for vision development and supporting the infant’s immune function. These fat-soluble carotenoids also have an antioxidant effect, protecting cells against oxidative stress and maintaining the health of the skin and mucous membranes.

Thus, a balanced diet, based on a variety of fresh vegetables and fruits, provides the necessary micronutrients for maintaining lactation and optimizing the health of the mother and child. Adjusting the diet according to individual needs and infant reactions ensures a harmonious nutritional transition and prevents potential food intolerances or metabolic imbalances.

Forbidden foods and fruits when breastfeeding – What can and cannot you eat when breastfeeding?

Although there are no absolute dietary restrictions, certain food categories require increased attention due to their potential impact on the infant’s health. Contaminants such as methylmercury, alcohol, and caffeine can cross the breast milk barrier and affect the newborn’s neurological and behavioral development, while processed or potentially irritating foods can affect its digestion and food tolerance.

Consumption of fish with high mercury content, such as shark, swordfish, king mackerel, or tilefish, should be avoided, as mercury has a neurotoxic effect and can affect the infant’s cognitive and motor development. Instead, it is recommended to choose fish with low mercury content but rich in omega-3 fatty acids, such as salmon, sardines, herring, or trout, which are essential for brain and retina development.

Alcohol, due to its ability to rapidly enter breast milk, should be consumed with extreme caution. According to medical recommendations, in case of occasional consumption, it is recommended to wait at least 2-3 hours before the next breastfeeding session to allow for alcohol metabolism. Frequent or large consumption can affect the infant’s sleep patterns and reduce the milk ejection reflex.

Breastfeeding: substances with an impact

Caffeine, present in coffee, black tea, green tea, energy drinks, and chocolate, can cause irritability, restlessness, and sleep disturbances in infants. Despite the fact that a moderate dosage (equivalent to 1-2 cups of coffee per day) is considered safe, the baby’s individual sensitivity can vary. In the case of infants who exhibit hyperexcitability or difficulty falling asleep, reducing caffeine intake may be beneficial.

Ultra-processed foods, rich in refined sugars, trans fats, and artificial additives, do not offer significant nutritional intake and can affect the mother’s energy levels, favoring blood sugar fluctuations and fatigue. Additionally, high consumption of processed foods can contribute to systemic inflammation and long-term metabolic imbalances. It is preferable to opt for a diet based on whole foods, rich in essential vitamins, minerals, and fiber.

At the same time, certain potentially irritating foods, such as garlic, onions, cabbage, legumes, and spicy foods, can alter the taste of breast milk or cause digestive discomfort to the infant, manifested by colic or bloating. Tolerance varies from one infant to another, which is why it is recommended to monitor the baby’s reactions after consuming these foods and adjust the diet according to individual tolerance.

To support both the increased nutritional needs during breastfeeding and optimal breast milk production, meal planning should be balanced, providing adequate intake of essential macronutrients and micronutrients.

A nutritious breakfast should include complex carbohydrates, quality proteins, and healthy fats, contributing to maintaining optimal energy levels and regulating postpartum metabolism. Oatmeal porridge prepared with milk or calcium-fortified plant-based drinks, enriched with berries and nuts, offers an ideal combination of soluble fiber, antioxidants, and essential fatty acids. Adding a boiled egg or a slice of whole-wheat bread with avocado improves the intake of choline, vitamin B12, and monounsaturated fats, elements essential for nervous system health and optimal brain function.

Lunch should be substantial, offering a balanced combination of protein, fiber, and healthy fats to prevent sudden blood sugar drops and support the postpartum recovery process. A complete salad with grilled chicken breast, quinoa, colorful vegetables, and pumpkin seeds provides a wide range of essential micronutrients, such as iron, zinc, and magnesium, contributing to replenishing nutrient stores depleted during pregnancy. Alternatively, a whole-wheat tortilla wrap with hummus, grilled vegetables, and beans can be an excellent source of plant-based protein, fiber, and phytonutrients, while also being a quick and easy option to consume while caring for the baby.

Breastfeeding: food ideas and recipes

A nourishing yet easily digestible dinner is recommended. This way, nighttime recovery of the body is supported. Digestive discomfort is avoided. Baked salmon is an excellent source. It contains omega-3 DHA fatty acids. It also provides high-quality protein. Vitamin D is important. It contributes to the baby’s neurological development. It helps maintain maternal health. Pairing it with broccoli is beneficial. Broccoli is a vegetable rich in calcium. It also contains vitamin K. Sweet potatoes are important.

Infant colic is a frequent challenge in the first months of life, characterized by episodes of prolonged and seemingly inexplicable crying. Although the exact mechanism of colic is not fully elucidated, some theories suggest that the immaturity of the digestive system and imbalances in the gut flora may contribute to their occurrence. In the case of breastfeeding mothers, maternal diet can indirectly influence the baby’s digestive symptoms, although there is no conclusive scientific evidence directly correlating the consumption of certain foods with the onset of colic.

Careful monitoring of the baby’s reactions to different foods in the maternal diet can provide useful clues in identifying potential triggers. Certain foods, such as legumes (beans, lentils, peas), cruciferous vegetables (cabbage, broccoli, cauliflower), and dairy products, may exacerbate abdominal discomfort in some sensitive infants. Also, caffeine, chocolate, and spicy foods could influence the composition of breast milk and the baby’s digestive tolerance, which is why temporarily reducing them from the diet may be beneficial if a correlation with increased colic is observed.

In this regard, adopting a balanced and easily digestible diet can contribute to maintaining digestive health for both mother and infant. Sources of lean protein, such as poultry, fish, and eggs, provide essential amino acids necessary for the child’s growth and development without overloading digestion. Complex carbohydrates from brown rice, quinoa, and sweet potatoes provide a stable energy supply while supporting the health of the gut microbiota. Vegetables with low insoluble fiber content, such as carrots, zucchini, and pumpkin, are well-tolerated and can help reduce digestive discomfort.

Breastfeeding: colic and diet

Probiotics, whether in the form of supplements or from natural food sources such as yogurt, kefir, and unpasteurized sauerkraut, can support the balance of the intestinal microbiota in both mother and infant, thus reducing the risk of digestive irritation. Adequate hydration is essential for maintaining optimal breast milk production and efficient digestive transit. Regular consumption of water, well-tolerated herbal teas (such as fennel and chamomile), and nutritious soups can contribute to maintaining optimal digestive balance.

What should a breastfeeding mother eat – Hydration and fluid intake during breastfeeding

Optimal hydration during breastfeeding is essential. It maintains adequate breast milk volume. It supports the maternal body’s hydro-electrolytic balance. The increased fluid requirement is determined by additional losses through breast milk. An daily intake of approximately 2.5-3 liters of fluids is recommended.

Water is the safest and most effective source of hydration. It helps maintain essential metabolic functions. It regulates body temperature. It prevents dehydration. Regular water consumption is fundamental. It should be distributed evenly throughout the day. It maintains constant milk secretion. An important physiological signal of increased hydration needs is thirst. Fluids should be consumed preventively. Not just as a response to thirst.

In addition to plain water, fluids with high nutritional value contribute to optimal intake of essential nutrients. Vegetable soups and chicken broth provide hydration. They also provide electrolytes and amino acids. They are necessary for postnatal recovery. They replenish mineral reserves. This is especially true for mothers who have had significant blood loss during childbirth.

Breastfeeding: hydration

Carefully selected herbal teas are helpful. These include chamomile, fennel, or anise. They offer an additional beneficial effect. They reduce oxidative stress. They support digestion. Fennel, in particular, has been associated with a galactogogue effect. It promotes the production of breast milk. However, it is essential to avoid excessive consumption of certain medicinal plants. These have hormonal or toxic potential. These include sage, mint, or licorice. They could negatively affect milk secretion.

Homemade smoothies are an excellent option. They hydrate. They also provide nutritional intake simultaneously. Combining antioxidant-rich fruits is ideal. These include blueberries and strawberries. They can be combined with green vegetables (spinach, kale). Protein sources are helpful. These include yogurt, almond butter. They support the mother’s increased energy needs. They also provide essential vitamins and minerals for the baby’s health.

Milk and calcium-fortified plant-based alternatives can be included in the daily diet. These include almond, oat, or soy milk. They contribute to maintaining bone health. They prevent nutritional deficiencies. It is recommended that these products be sugar-free. They should be consumed in moderation. The mother’s digestive tolerance should be taken into account.

Regarding drinks that should be limited or avoided, coffee and other sources of caffeine should be consumed in moderation. These include black tea, green tea, energy drinks. Caffeine passes into breast milk. It can affect the baby’s sleep and agitation. Consumption should be limited to approximately 200-300 mg of caffeine per day. This is equivalent to one to two cups of weak coffee.

Breastfeeding: drinks

Alcohol is not recommended during breastfeeding. It can pass into breast milk. It can have negative effects on the infant’s nervous system. If a small amount of alcohol is consumed occasionally, it is advisable to wait at least 2-3 hours before the next breastfeeding session. This allows for its metabolism by the body.

Nutritional supplements recommended during breastfeeding

During breastfeeding, nutrient needs are increased. In certain situations, dietary supplements may be necessary. Thus, both the mother’s health and the infant’s optimal development are ensured. Although a varied and balanced diet remains the foundation of adequate nutrition, nutritional deficiencies can occur. This depends on lifestyle, dietary preferences, or postpartum physiological status. The administration of supplements must be done under the guidance of a specialist. This way, excesses are avoided. Potential drug interactions are prevented.

Postnatal multivitamins are a useful option. They are for mothers who cannot cover their daily micronutrient needs exclusively through diet. They contain an optimal combination of essential vitamins and minerals. These include B vitamins. Vitamin A. Vitamin C. Vitamin D. Essential trace elements. These supplements are particularly important in cases of inadequate dietary intake. They are also important in cases of restrictive diets. These include vegetarianism or veganism.

Vitamin D plays an essential role in bone metabolism. It aids in the optimal functioning of the immune system. Insufficient sun exposure or a diet low in vitamin D-rich foods can lead to a deficiency. These include fatty fish, eggs, or fortified dairy products. During breastfeeding, supplementation with 600-2000 IU per day may be necessary. This way, an optimal serum level is maintained. Breast milk does not contain adequate amounts of vitamin D for infants.

Breastfeeding: supplements

Calcium is important for the mother’s bone health. Its need increases significantly during breastfeeding. If calcium intake from the diet is insufficient, the body may resort to maternal bone reserves. These include dairy products, leafy green vegetables, seeds, almonds, fortified tofu. Thus, the infant’s needs are met. Supplementation may be indicated. It is particularly important for women who do not consume dairy products. It is also indicated for women who are at increased risk of osteopenia or osteoporosis.

Iron is another useful mineral during this period. It is particularly important if the mother had significant blood loss during childbirth. It is also important if the mother has postpartum anemia. Although breast milk contains a highly bioavailable form of iron, maternal reserves must be maintained. This way, states of exhaustion, dizziness, and low immunity are prevented. Iron supplementation is recommended based on serum hemoglobin and ferritin levels. Excessive administration is avoided. It can cause digestive side effects.

Omega-3 fatty acids, especially DHA (docosahexaenoic acid), are critical. They are necessary for the infant’s neurological and visual development. Ideally, these fatty acids should be obtained from fatty fish (salmon, sardines, mackerel). For women who consume insufficient amounts or avoid fish, supplementation with purified fish oil or microalgae may be beneficial.

Iodine is necessary for optimal thyroid gland function. This applies to both mother and infant. Iodine deficiency during breastfeeding can affect the baby’s cognitive development. In case of insufficient dietary intake, supplementation with 150-250 mcg of iodine per day may be indicated. These include fish, dairy products, eggs, iodized salt. This is done according to international recommendations.

Breastfeeding: nutrients

Numerous myths circulate around nutrition during breastfeeding. These can influence mothers’ choices. They can generate unnecessary anxiety. It is essential to rely on scientific evidence. Also, on updated medical recommendations. Thus, optimal nutrition is ensured. This applies to both mother and infant.

One of the most common myths is that certain foods must be completely eliminated from the diet. These include dairy products or spicy foods. In reality, most infants tolerate the foods consumed by the mother very well. Unnecessary dietary restrictions can limit the intake of essential nutrients.

Another misconception is that mothers must consume cow’s milk to produce breast milk. In reality, breast milk production does not depend on animal milk consumption. It depends on adequate hydration. And a balanced diet is also necessary.
