Caffeine and Pregnancy



Caffeine and Pregnancy

In recent years, research has emerged demonstrating that coffee, in moderation—may have a number of previously unrecognized health-promoting properties.

However, it's important to understand that coffee is both a potent drug, and a whole food provided it's organically grown. The drug element of coffee can present problems for pregnant women.

Caffeine can significantly impact the growing fetus as it is able to freely pass through the placenta, and since caffeine does not provide any benefits to your baby, only potential hazards, it is strongly recommend that pregnant women avoid ALL forms of caffeine.

Unfortunately, most people (pregnant or not) use coffee for its energy-boosting properties, which can end up serving as a band-aid for poor nutrition. If you're supplying your body with the nutrients it needs, you simply won't need the extra energy boost.

If this sounds like you, you may want to consider taking a look at your dietary habits. Proper nutrition clearly becomes even more important when pregnant or planning a pregnancy.

Coffee in Pregnancy Tied to Smaller, Later Newborns

In a recent Norwegian study, which included data on nearly 60,000 women, coffee and other caffeinated beverages increased the odds of delivering a low birth weight baby and/or extended the gestation period.

Lead researcher Dr. Verena Sengpiel, an obstetrician/gynecologist believes women are advised to limit their caffeine intake.  

 

Higher caffeine consumption was found to be associated with an increased risk for reduced birth weight. Every 100 mg of caffeine consumed by the mother per day equated to a nearly one ounce reduction in the baby's weight at birth. Every 100 mg of caffeine also increased the length of the pregnancy by five hours.

Interestingly, when the source of the caffeine was coffee, the length of the pregnancy was extended by eight hours. The reason for this difference is unknown. Seeing how your average cup of coffee contains anywhere between 95-200 mg of caffeine, it may be best to err on the side of caution.

We do know that caffeine crosses the placenta and the baby is not able to metabolize it very well, it may affect some of the factors associated with growth.

Caffeine During Pregnancy May Damage Your Baby's Heart

Previous animal research from 2009 found that drinking the equivalent of just two cups of coffee while pregnant could be enough to affect long-term heart function of the offspring. They also found that this minimal exposure could lead to increased levels of body fat in males, when compared to offspring not exposed to caffeine in the womb. Scott Rivkees, Yale's Associate Chair of Pediatric Research and a senior researcher on the study.

"Our studies raise potential concerns about caffeine exposure during very early pregnancy, but further studies are necessary to evaluate caffeine's safety during pregnancy."

"Caffeine is everywhere: in what we drink, in what we eat, in pills that we use to relieve pain, and even in candy... This report shows that despite popular notions of safety, there's one place it probably shouldn't be: in the diet of an expectant mother."

When You're Eating for Two...

There is rarely a more nutritionally demanding time during a woman's life than pregnancy (and later breastfeeding), when your intake of nutrients from foods and supplements are needed not only to keep your body running but also to nourish and support your rapidly growing baby. Proper nutrition is crucial at all stages of fetal development, and if mom doesn't eat right, her growing baby won't either.

If you're a woman in your childbearing years and you're planning to have children any time soon, it's imperative that you start eating healthy now. Research7 published just last year showed that women who ate a vegetable-rich diet during the year before pregnancy had a significantly lower risk of having a baby with certain birth defects as women who ate an unhealthy high-sugar diet.

Crucial Nutrients for Pregnant Women (and Women of Childbearing Age)

Healthy nutrition cannot be limited to a handful of nutrients; it can only be achieved by eating a variety of whole, high-quality foods daily. I cannot stress this enough, as if you seek to make up for a diet of processed foods by taking a multi-vitamin or eating a salad here and there, you are deceiving yourself and missing the point -- and the benefits.

·         Fermented Foods and/or Probiotics: Nearly everyone can benefit from optimizing the balance of good vs. bad bacteria in their gut using probiotics, but if you are pregnant or planning to be, this is of utmost importance to you and your new baby. One of the best ways to do this is to avoid sugar and processed foods and to include fermented foods in your diet. A high-quality probiotic supplement is an option, especially if you don't eat many fermented foods.

·         Vitamin D:  Your main source of it should be from the sun, not from food. Supplementation may be necessary in winter months.

·         Vitamin B12: B12 is critical for normal neurological development and maintenance, and shortages can result in permanent birth defects.

·         Folate in the form of Metafolate: Another B complex vitamin (vitamin B9), folic acid deficiency at the time of conception is known to increase the risk for birth defects such as spina bifida. 

·         Animal-based Omega-3 Fats: Most women have major deficiencies of animal-based omega-3 fat like EPA and DHA, which is unfortunate because fetal cells cannot form omega-3 fats, meaning a fetus must obtain all of its omega-3 fatty acids from mother's diet. DHA (docosahexaenoic acid) is so essential to a child's development that if a mother and infant are deficient in it, the child's nervous system and immune system may never fully develop, and it can cause a lifetime of unexplained emotional, learning, and immune system disorders. Studies have shown that sufficient levels of omega-3 fats optimize brain growth in children, especially during the third trimester. But because the fetus depends on the mother's DHA sources, the constant drain on a mother's DHA reserves can easily lead to a deficiency and some researchers believe that preeclampsia (pregnancy-related high blood pressure) and postpartum depression could be linked to a DHA deficiency. The DHA in animal-based omega-3 fats will also help to prevent the vast majority of premature deliveries.

Hypoxia


MOM!!!  Please take me out of the car seat- I can’t breathe

Many mothers complain that their babies appear to be overtired and irritable with many thinking that it is colic.  A study on 200 infants has shown that infants in a bucket type car seat for prolonged periods can cause oxygen deprivation. A simple car seat insert that maintains a baby’s head in a neutral position without its chin touching its chest reduces the severity of hypoxic events while the infant is in the car seat, but does not reduce the overall number of hypoxic events. Often the babies head flops forward or off to the side occluding the airway causing lack of oxygen to baby. Many parents will use head supports to prevent the flopping forward but ultimately the best idea so your child have sufficient oxygen is limiting car seat time by shorter travel times- meaning more stops along the route and limiting ‘bucket seat time’. Other ways to decrease the time in the seat is to remove the child from the car seat when you have arrived at your destination and carry the child- remove them from the car seat and carry or baby wear your child- especially if they are sleeping. According to the study, reported online in Pediatrics, mean oxygen saturation declined significantly following 60 minutes in a car bed (96.3%) and 60 minutes in a car seat (95.7%), compared with 30 minutes in a hospital crib (97.9%, P<0.001).The average minimal oxygen saturation and total time spent with an oxygen saturation below 95% also differed significantly in car seats or car beds, versus a hospital crib. Similar results came from a study of 50 infants who stayed in each position for 120 minutes. The cars seat is only designed for car travel and not meant to replace the bed itself. In their report, the authors of the study noted that previous research has shown that healthy infants may develop respiratory compromise while in car seats. The results give pause for concern because "even mild airway obstruction has been associated with behavioral problems and IQ deficits," the authors said. Car beds and seats "are often used for many hours at a time for reasons other than travel," they added. "Infants placed in these devices for prolonged periods of time are, thus, at increased risk for recurrent hypoxic events."The researchers concluded that because car seat use, even with an insert, is associated with an increase in desaturation events, caregivers should not use car seats to sleep infants outside of the car. They also should not keep infants in car seats for any longer than absolutely necessary and should always attend to them while they are in the devices.
