The Contented Calf Cookbook for Breastfeeding Mums
Inspired by a friend’s quest to improve her milk supply and her discovery of lactogenic foods, Elena Cimelli created this unique cook book with food writer Jassy Davis to give new parents a one-stop collection of delicious, lactogenic meals, snacks, drinks and treats.
Drawing on Elena’s own experience of cooking and freezing meals ahead of the birth of her daughter, the majority of the meals are designed to be made and frozen in the weeks leading up to the birth of your child. All the recipes are nourishing and full of flavour and they’ll appeal to partners, children, friends and non-breastfeeding mums, too.
a) Anatomy of the human breast
The inside of a breast looks like a bush – with the nipple being the stump of the bush and the milk duct ‘branches’ and alveoli ‘leaves’ fanning out inside. It is composed of essentially four parts: alveoli or glands, milk ducts and fat, plus connective tissue. The alveoli group together into larger units called lobes. There will be around 9 – 12 main milk lobes in each breast. Each lobe has a main duct, leading from the nipple back through the breast to the lobe – like a main branch of the bush. Multiple smaller ducts branch off, forming the milk lobe itself. The ‘leaves’ of this bush are the alveoli – sac-like round glands, lined with milk-producing cells, lactocytes. It is inside each alveolus that the milk is produced, travelling down the ducts and out of the nipple.
b) How breast milk is made
The process of making breast milk (lactogenisis) is heavily dependent on two hormones – prolactin and oxytocin. Each hormone needs an equivalent receptor located wherever the hormone’s influence is required (ie the breasts), and the receptors must be an exact match to the hormone. In addition, there needs to be enough receptors for the amount of hormone. Both prolactin and oxytocin are secreted by the pituitary gland (a pea-sized gland at the base of the brain).
|One||The hormone prolactin is needed for milk to be produced. Prolactin receptors are on the walls of the lactocytes (the milk-producing cells of the alveoli). The receptors allow the prolactin in the bloodstream to move into the lactocytes and stimulate milk production.|
|Two||As the alveoli fill up with milk two things happen:1. They stretch, which changes the shape of the lactocytes so they cannot absorb any more prolactin, therefore slowing the rate of milk production.2. The breast milk itself contains a protein called Feedback Inhibitor of Laction (FIL). When the breast is full of milk, and so there is an increased amount of FIL present, the FIL gives the message to the lactocytes to stop producing milk.|
|Three||The baby’s suckling stimulates the hormone to be released – oxytocin. (At the same time, the pituitary gland also releases more prolactin too.) Oxytocin causes the muscles around the alveoli to contract, squeezing the milk into the ducts, which swell behind the nipple, full of milk. The motion of the baby’s tongue as they suck, draws the milk into their mouth – though they must have a good mouthful of breast to be able to reach the ducts and feed effectively.|
|Four||As the milk empties out of the alveoli, the prolactin receptors return to their normal shape, so the prolactin flows back into the lactocytes and milk production starts again. The milk that is produced as the baby feeds is higher in fat and more satisfying.|
Prolactin Receptor Theory proposes that frequent milk removal in the first several weeks of feeding increases the number of receptor sites. With more receptors, more prolactin can flow into the lactocytes, and milk production capacity increases.
Prolactin levels in the body start to rise around half-way through pregnancy, surging to their highest levels at the time of birth. However, during pregnancy high levels of progesterone, produced by the placenta, interact with the prolactin receptors on the walls of the lactocytes to inhibit milk production. But these progesterone levels fall dramatically once the placenta is delivered, and the prolactin is able to start having an effect.
The level of prolactin drops continuously until it plateaus around three months after birth. However the more frequent the prolactin surge, experienced during feeding, in the first several weeks, the higher the baseline for on-going milk supply levels. The more successful breastfeeding is in the first few weeks, the more successful it is likely to be going forward.
So if you’re breastfeeding and need support, it is really is key to get it in the first few weeks. For more information, please visit our Breastfeeding Support page: www.contentedcalf.com/support
(West & Marasco, 2009)
2. A lactogenic diet & low milk supply
There are many factors that determine a successful breastfeeding experience and sufficient milk supply for your baby. It is a complex process and there can be many unknown reasons why breastfeeding works for some and others are not so lucky. If you are having problems feeding, I would advise that you call the NHS, NCT or La Leche League breastfeeding helplines. For more information on breastfeeding support, please visit our Breastfeeding Support page: www.contentedcalf.com/support
Please remember, food is just part of the picture. It is not a magic bullet to fix all breastfeeding problems. Indeed, in their book “A Breastfeeding Mother’s Guide to Making More Milk” Diana West and Lisa Marasco introduce the concept of ‘The Milk Supply Equation’, which is as follows:
1. Sufficient glandular tissue
+ 2. Intact nerve pathways AND ducts
+ 3. Adequate hormones AND hormone receptors
+ 4. Adequately frequent, effective milk removal and stimulation
= GOOD MILK PRODUCTION [i]
Looking at the above equation, there’s not much we can do about points 1 and 2 – these are down to an individual’s antomy. (A very small number of women can suffer from breast hypoplasia – the incomplete development of the glandular tissue in the breast.)
With regards to point 4, if a new mum has breastfeeding problems, Midwives, Health Visitors and Breastfeeding Counsellors can help support her and her baby with effective feeding, which will stimulate milk production. (See www.contentedcalf.com/support for further details of support organisations.)
But what do most new mums really know about point 3, hormones and the role diet can play in lactogenesis (the process of making milk)? It’s here that a lactogenic diet can play a role, by helping to increase the levels of prolactin in the bloodstream, and therefore potentially increase the quantity of milk made, as well as help improve the quality and help the flow. A lactogenic diet, along with a correct latch and frequent feeding, is one of the tools in a whole toolbox of things to help with your breastfeeding experience.
(Lieberman & Cassar-Uhl, 2011)
(West & Marasco, 2009)
a) Prolactin and milk supply
As we have seen above, the major hormone involved in milk production is prolactin. Anything that helps our bodies increase the level of prolactin in our bloodstream can help increase milk supply. The information below tries to show how certain foods can help increase that level of prolactin:
Tryptophan is one of the 10 essential amino acids in the human diet, which the body uses to make proteins. On top of this, it also serves as a precursor for seratonin. Seratonin is our feel good neurotransmitter. When seratonin levels in the brain rise, so do our mood levels.
It also counter-acts dopamine, which suppresses prolactin (needed for milk production). So anything that keeps dopamine levels low, in turn keeps prolactin levels high and aids milk production.
High tryptophan = high seratonin = high prolactin.
The good news is that tryptophan is found in lots of foods. Foods containing tryptophan include:
- Fruit: apricot
- Grains: oats, barley, wheat
- Herbs & spices: basil, chives, black pepper, fennel, garlic
- Leafy greens: watercress, spinach
- Legumes: beans (black, green, kidney, string), chickpea, peas
- Meat & fish: Calf liver, halibut, lamb, salmon, tuna, venison, poultry (especially turkey)
- Natural sugars: honey, malt syrup, maple syrup
- Nuts: almond, cashews
- Seeds: evening primrose, pumpkin, sesame, sunflower, fenugreek
- Vegetables: asparagus, carrot, cauliflower, celery, fennel, jerusalem artichoke, lettuce, onion, potato, sweet potato.
(Ben-Jonathan & Hnasko, 2001)
(Dopamine definition, 2004)
(George Mateljan Foundation)
ii) Sedative vegetables
There is also a small group of herbs and foods containing substances that can act as sedatives. Sedative foods serve as natural opiates, which suppress dopamine, encouraging increased production of prolactin.
Foods considered sedating include: fennel, lettuce, onion, potato.
Polysaccharides are natural forms of long-chain sugar, which have healing or immune stimulating effects on the body. Foods containing polysaccharides, specifically beta glucan, are able to stimulate prolactin secretion and so raise prolactin levels in the blood. (Lactation studies on rats and cattle showed beta glucan measurably raised prolactin levels in the blood and increased milk production.)
Foods containing polysaccharides include: barley, oats, yeast.
(Sepehri, Renard & Houdebine 1990)
b) Oxytocin and milk flow
The role of oxytocin is to squeeze the milk out of the alveoli into the ducts which lead down to the nipple, by causing the muscles around the alveoli to contract. However, if the production of oxytocin is suppressed, this ‘milk-ejection reflex’ is inhibited. If the milk is not fully ‘let down’ (however successful actual milk production has been), only a little amount of milk can be removed. The breasts can then not be fully emptied and so the message to make more milk is not sent back to the brain.
The baby’s suckling stimulates oxytocin to be released. However, stress hormones, such as adrenaline suppress the production of oxytocin. As well as trying to keep your stress-levels low, it is also very important to eat meals and snacks throughout the day, as hunger can induce stress too.
In addition to ensuring you eat regularly throughout the day, in her book Mother Food, Hilary Jacobson provides a list of different remedies for problems with let-down or flow, originally recommended by the 1st Century AD Greek Doctor Dioscorides, which include the following foods and herbs: anise, basil, dill, fennel (garden and wild), lettuce.
(Letdown Reflex When Breastfeeding)
(Makina & Krasnovskaia, 1999)
c) Composition of breast milk and quality
Breast milk is roughly made up in the ratios listed in the table below:
|Protein (g/100 ml)|
|Carbohydrate (g/100 ml)|
|Minerals (g/100 ml)|
Breast milk draws its make-up from the food a mother eats. If the diet is found lacking, content is obtained from mother’s bodily stores. Obviously eating a healthy, balanced diet is the most sensible way of ensuring the mother is getting everything she needs, as well as the baby. In particular, two groups of ‘good fats’ are worth mentioning:
i) Essential Fatty Acids
DHA and other Omega 3 fatty acids are fundamental to the development of the brain in infancy and childhood. Breast milk boosts the brain growth because, provided the mother herself eats foods rich in Omega 3 fatty acids, it contains lots of DHA. Having a diet with good levels of DHA in it has also been linked to promoting a mother’s own psychological and emotional well-being, and helping fight against post-natal depression.
Essential Fatty Acids are divided into two main types: Omega 6 and Omega 3. The body cannot make these fatty acids itself, so we need to ingest them through foods and/or supplements. A Texas study from 2000 showed that taking additional DHA significantly increased the DHA content of the nursing mothers’ milk.
Food sources for Omega 6 are: butter, cream, eggs, grains, meat fat, nuts, whole-fat milk.
Food sources for Omega 3 are: flaxseed oil, green leafy vegetables, legumes, organic eggs and fish, walnut oil. Sources specifically for Omega 3 derivative DHA include: algae extract, cod-liver oil, fish oil.
- (Breastfeeding mom’s diet and baby’s brain development)
- (Jacobson, 2007)
- (Jensen, Maude, Anderson & Heird 2000)
ii) Coconut Oil
Your body’s anti-microbial fatty acid (monolaurin) is made from lauric acid. Monolaurin is anti-viral and anti-bacterial. If you add foods rich in lauric acid your diet, the amount in your breast milk increases substantially, which may help breastfed babies fight colds and infections. In countries where coconut oil is part of the staple diet, lauric acid levels in breast milk can be as high as 21% (normally around 3%).
d) Other areas of a lactogenic diet
As we have seen the milk production process is very hormonally driven, so one group of foods to look at are those rich in saponins – a sweet, soap-like substance with immune-stimulating and antibiotic effects. Some saponins can mimic the human hormones they resemble. The body can use them as precursors to make hormones, and they may influence production of hormones from the pituitary gland. This may aid production of both prolactin and oxytocin, both of which are made in the pituitary gland.
Foods rich in saponins include: asparagus, carrots, green beans, oats, peas, potatoes.
(Broadhurst & Duke PhD)
ii) Reduction in water retention
There is a possible connection between water retention and delayed milk production – often a mother’s milk does not come in fully until any swelling experienced during the pregnancy subsides.[iii] Therefore foods which are high in beta-carotene, antioxidants and are diuretic, and so detoxify liver and kidneys helping to relieve water retention, are considered lactogenic.
Foods high in beta-carotene, antioxidants and diuretics include: asparagus, beetroot, carrot, dandelion, green leafy vegetables, sweet potato.
(West & Marasco, 2009)
Some women who are continuing to breastfeed after they have re-started menstruating have noted that they experienced lower milk production prior to their periods. Although this link has not formally studied, Patricia Gima (IBCLC) has reported calcium/magnesium supplements have helped several of her clients, often within 24 hours.
Foods high in calcium include: almonds, chicken soup, green beans, green leafy vegetables, legumes, peas, sesame seeds.
(West & Marasco, 2009)
Some low-supply mothers also see an increase in supply if they increase intake of protein.
e) Lactogenic and anti-lactogenic foods
i) A comprenhensive lactogenic list & the ‘Top Ten’ lactogenic foods
- Fats & oils: Butter, coconut oil, sesame seed oil, extra virgin olive oil, walnut oil

- Herbs & spices: Aniseed, basil, black pepper, caraway seed, chives, cinnamon, coriander, cumin, curry, dill, fennel, fenugreek, garlic, ginger, marjoram, sea salt, thyme, turmeric
- Leafy greens: Dandelion leaves, kale, lettuce, rocket, seaweed, spinach, watercress
- Legumes: Chickpeas, beans (black, green, kidney, lima, string), lentils, mungbeans, peas

- The ‘Top Ten’:
- Almonds, apricots, barley, dates, fennel, fenugreek, figs, oats, rye, sesame
ii) The anti-lactogenic list
As well as foods and herbs that can help improve milk supply, there are those that may decrease supply, particularly if consumed in large quantities or eaten exclusively.
PLEASE NOTE: Most mothers will not be affected by eating these foods. Nearly all mothers with a normal supply can enjoy these foods without any problems.
However, as a small number are, it’s worth noting them.
Caffeine: An increase in stress hormones can lead to the constriction of the capillaries in the breasts and possibly affect supply. Foods and drinks containing caffeine, which increases stress hormones, can be problematic, such as black tea, coffee, green tea, caffeinated soft drinks and chocolate.
Astringent foods: These can cause sensitive tissue to constrict and can also lead to restricted blood circulation in the breasts. So citrus juice, citric acid and all foods containing citric acid may need to be avoided or reduced. Included in this group are Vitamin C supplements, sour berries and fruit and red raspberry leaf tea.
Vitamins & additives: Anything that increases dopamine, which suppresses prolactin production, is best avoided or eaten in small amounts, in particular Aspartame and Vitamin B6. Herbs: Avoid lemon balm, parsley, peppermint, rosemary, sage, spearmint and thyme in large quantities as they are suspected of drying up a mother’s milk supply.
It’s also worth avoiding foods that either make your breast milk more difficult to digest or that your baby seems not to like the taste of, such as cabbage, Brussel sprouts and cauliflower, as this may lead to them drinking less and your breasts therefore producing less.

In many cases of suspected low milk supply, the real problem may actually be how much milk your baby is getting. If your baby isn’t latching on well, they’ll struggle to get enough of milk, so help with improving your baby’s latch should help. In addition, your breasts produce milk to match your baby’s demands. The more they feed, the more milk you’ll produce, so frequent feeding and feeding on demand can help too. However, because the amount of breast milk produced is linked to how much is removed, on-going problems with feeding can reduce how much you produce in the long run.
There’s lots of expert help available. Ask your midwife or health visitor if she can recommend a breastfeeding specialist. There are also many local and national support groups to help women with breastfeeding, but perhaps the most well known are the NHS, NCT and La Leche League. You can find more information on their websites.
