Nutrition for Fertility

In the 1930s, Francis Pottenger, MD conducted a ten-year-long study in which nearly a thousand cats were fed the same basic diet of milk, meat and a small dose of cod liver oil.

“The healthiest cats were the ones who received raw meat and raw milk. This was the only group to produce generation after generation of healthy kittens with broad faces, adequate nasal cavities, broad dental arches, strong and correctly shaped teeth and bones, excellent tissue tone, good-quality fur with a minimum of shedding and an absence of gum disease. These cats were resistant to infections, fleas, and internal parasites. They showed no sign of allergies and were gregarious, friendly and predictable in their behavior patterns. Miscarriages were rare and litters averaged five kittens, which the mothers nursed without difficulty.

Another group received raw milk and cooked meat. The cats in this group developed skeletal and dental deformities, heart problems, vision problems, thyroid imbalances, infections of the kidney, liver, testes, ovaries, and bladder, arthritis and inflammation of the joints, and inflammation of the nervous system with paralysis and meningitis. Their second and third generations had abnormal respiratory tissues. Cooked-meat cats were so irritable that some of the females were named Tiger, Cobra, and Rattlesnake, while the males were docile and passive, a sexual role reversal not seen in the raw-food cats. Vermin and intestinal parasites abounded and skin lesions and allergies appeared frequently. Adult cats died of pneumonia or infections of the bone while kittens died of pneumonia and diarrhea. The cooked-meat cats had serious reproductive problems including sterility, miscarriage, a lack of maternal instinct and difficult labors with high infant mortality rates. Many females died in labor.

The cats fed raw meat with pasteurized milk showed similar changes, and those fed evaporated milk showed even more damage, while the most marked deficiencies occurred among those fed sweetened condensed milk.

Because the health of each new generation was adversely affected by its parents’ inferior diet, the cooked-food kittens had even more problems, and there were no fourth generation kittens in any of the cooked-food groups because the third generation always died before reproducing. Had antibiotic drugs been available, these kittens might not have died of pneumonia and other infectious diseases, in which case the experiment could have continued through longer chains of deformed offspring.

One of Dr. Pottenger’s most exciting discoveries was that the health deterioration caused by cooked foods can be reversed, although it took four generations to completely restore perfect health to cats whose ancestors ate cooked meat or pasteurized milk.”     – from the Weston A.

For cats, who are obligate carnivores, and have evolved eating raw meat, it’s different from human nutrition, but a few of the ideas are the same:  

  1. The more we mess with our food, and the further away our food gets from our natural human diet, the more prevalent fertility issues become.  
  2. Your fertility issues are not your fault, but may be from some missing nutritional blocks from up to four generations back.

In many traditional cultures, pregnancy and preconception diets center around raw, whole dairy products, raw fish and fish eggs, organ meats, and local plant foods.  Below are some of the key components for a superior prenatal, pregnancy, and antenatal diet.  

VITAMIN A

The best sources of Vitamin A come from fish-liver oils, liver, egg yolks, butter, and unpasteurized cream.  Vitamin A is essential for any body function requiring cellular proliferation (i.e. growing a human).  

Beta-carotene, which your body converts into Vitamin A, comes from sources like sweet potatoes, carrots, and other fruits and vegetables.  While those vegetables are obviously good too, in a healthy person, only 3% is converted.  If you’re diabetic or have thyroid problems, the conversion rate is even lower.  Animal-based Vitamin A is pre-formed and absorbs directly into your body.  This is why the best foods for fertility and also for your baby are raw, whole (breast) milk, butter, and egg yolks.    

Many studies on Vitamin A and pregnancy show that it improves fertility and helps prevent birth defects.  Get your Vitamin A from food sources only, and not through a synthetic vitamin (i.e. the stuff you buy at the drug store).  The often-talked-about Vitamin A toxicity problem tends to only happen through synthetics.  

VITAMIN E

A study in 1922 called Vitamin E “Anti-Sterility Factor X” because rats couldn’t reproduce without it.  Vegetable oils are high in vitamin E, but also in polyunsaturated fatty acids, which deplete your body of Vitamin E.  Better sources of Vitamin E are whole grains, vegetables, fruits, nuts, seeds, and grass-fed beef.

Vitamin E supplements that are only “tocopherol” are lacking the other essential components of the Vitamin E complex.  Either get it through food or use a food-based vitamin that contains some of the above-listed foods.

VITAMIN D

Spending 20 minutes in the sun every day may not be the best way to optimize your Vitamin D levels, although it will help, depending on your skin color (darker skin absorbs less), whether or not you’re obese (increased BMI interferes with D absorbability), and the time of year and the prevalence of UV-B rays.  To be safe and ensure that you get enough Vitamin D, use food sources:  fatty fish and butter, or a cod liver oil supplement.  

Vitamin D is essential for cellular proliferation such as fetal skeletal and lung development, preventing Type 1 diabetes, and other important things.  

VITAMIN K

Vitamins K1 and K2 help with bone formation and nerve development.  K1 is found in leafy greens and K2 is found in fermented vegetables (like pickles and saurkraut) and grass-fed animal fats like cheese and liver.  Most diets worldwide eat some form of fermented foods.  If you’re not already, now’s the time to do so.  

DHA

Another fat-soluble vitamin, DHA is found in cod liver oil, fatty fish, and grass-fed animals.  It helps baby’s brain development and helps the mother prevent “mommy brain” which is a real thing where you feel a little bit dumb pretty much as soon as you get pregnant.

FOLATE

Everyone knows you need Folic Acid when you’re pregnant, but why?  Folate prevents birth defects and spontaneous abortion (miscarriage).  It encourages the production of red blood cells, and you need a lot of those to make a baby.  The rate of folate absorption depends on the body’s supply of zinc, and also the quality of the folate.  Folic acid is a synthetic version of folate, and the absorbability is relatively low.  However, the synthetic folic acid does prevent neural tube defects, so if the mother is not going to eat a folate-rich diet, she should take the supplement.  Folate-rich foods include liver, legumes, and greens.

BIOTIN

Essential for limb and palate formation, biotin is found in many food sources.  The best source is raw egg yolks, as cooking lowers the available biotin.  Other good sources are raw nuts and seeds, cauliflower, brown rice, oatmeal, and carrots.   

CHOLINE

Choline is essential for fetal brain formation.  In adults, choline deficiency can be underlying organ dis-ease such as fatty liver and muscle damage.  Foods with the highest amount of bioavailable choline are (are you sensing a pattern here yet?) eggs, liver, raw dairy, and wheat germ.  Other foods include meats, cruciferous vegetables, nuts, and legumes.  

GLYCINE

Glycine is an amino acid that adults don’t usually need to supplement.  During pregnancy, however, the fetus requires additional glycine through food sources.  The best food sources are skin (as in skin-on your chicken leg) and bones (as in bone broth or cartilage).  Meat and eggs deplete your glycine, so it’s important that meat and egg consumption is balanced with bone broth and meat with the skin on.  The fetus also uses folate to make glycine from another amino acid.  That said, it’s important to balance all the meat, bones, and skin with legumes, greens, and liver which are perfect sources of folate.  

ANTENATAL CARE

In Chinese medicine, we recommend that for one month the mom and baby stay home whenever possible.  This prevents the “evil wind” from invading the mother’s blood and qi deficient body until she regains her strength.  In other words, it’s for longevity and quick recovery.    

Also, most women after birth take an herbal tea with angelica root and other medicinal plants to replenish the blood supply.  Warm, nourishing foods like congee (rice porridge) with eggs and mutton are recommended.  A little bit of rice wine helps the milk supply! 

In many cultures, the placenta is consumed after birth, and this is becoming more popular in the US too.  I highly recommend it.  All of these practices help prevent post-partum depression, hemorrhaging, and help the milk supply.
