New Study Shows Preterm Birth 50% Less Likely With Healthy Diet
Updated 7th June 2021
The three specific diets included in the research include the alternative Mediterranean Diet, alternative healthy eating index and the diet of dietary approaches to stop hypertension (DASH).
The Mediterranean Diet is known for its emphasis on fresh vegetables, whole grains, nuts and healthy fats such as Extra Virgin Olive Oil.
The study was conducted by the National Institute of Child Health and Human Development (NICHD) Eunice Kennedy Shriver and was published in the American Journal of Clinical Nutrition.
It studied nearly 1,900 women who responded to questionnaires about their diets between weeks 8 and 13 of pregnancy. The participants were also asked to estimate what they ate in the previous three months. This allowed their responses to be analysed according to three measures of healthy eating: the alternative healthy eating index (AHEI), the alternative Mediterranean diet (AMED) and the diet of dietary approaches to stop hypertension (DASH).
The findings showed that women with a high score of the alternative Mediterranean diet (AMED) or dietary approaches to stop hypertension (DASH) diets between weeks 24 and 29 of pregnancy had a 50% lower risk of having a preterm birth. While women with a high alternative healthy eating index AHEI score between weeks 16 and 22 of gestation had a 32% lower risk of gestational diabetes than women with a low score.
These findings led researchers to report that healthier dietary patterns during periconception and pregnancy characterized by higher AHEI, AMED or DASH scores were associated with lower risks of common pregnancy complications, including gestational diabetes and hypertension, pre-eclampsia, and premature babies.
According to a report in explica.co , the research compliments an earlier study this year which warned that mothers who eat an unhealthy diet during pregnancy can put your kids on the path to weight gain and obesity. Without a doubt an interesting finding, considering the growing epidemic of childhood obesity in the world. Explica explained: This is how a group of doctors from Brigham and Women’s Hospital in Boston investigated the links between the diet of an expectant mother and the growth rates of her children between birth and adolescence. As expected, the team of researchers found that women who follow a diet based on the consumption of inflammatory foods during pregnancy are more likely to cause greater weight gain in children between three and ten years of age. This type of diet is characterized by a high consumption of ultra-processed foods and fast foods, which roughly stand out for their caloric intake and high content of sugars, artificial trans fats, sodium, refined flours and all kinds of processed meats.
Extra Virgin Olive Oil Could Help With Conception
Countless studies support the benefits of maintaining a healthy diet throughout pregnancy but did you know that a vast body of research suggests The Mediterranean Diet can help with fertility and conception?
In fact, The Mediterranean Diet – with its emphasis on vegetables, grains, fish and healthy fats such as the best quality extra virgin olive oil – can help with all stages of reproductive health from conception to pregnancy and beyond.
Dietician and Blogger Melanie McGrice, explains that extra virgin olive oil has 5 key features which makes it her ‘favourite oil to use when you’re trying to get pregnant’. She looks for oils that are:
- Low in bad saturated fats which can cause inflammation.
- Rich in antioxidants which can protect our eggs from damage.
- High in vitamin E which is a fat-soluble vitamin that has been found to be good for our uterine lining.
- Abundant in good monosaturated fats which have been found to decrease inflammation.
- Plentiful in omega 3 fats, which have been found to increase blood flow to our uterus and improve fertility hormones.
Melanie says that Extra Virgin Olive Oil is low in bad saturated fats, rich in antioxidants and rich in vitamin E, it contains some omega 3 fats and has a high proportion of monosaturated fats.
It’s not surprising that it gets her number 1 vote!
Fertility and pregnancy expert Emma Cannon agrees that good nutrition is of vital importance in improve your chances of conception.
“There is increasing evidence that fertility can be improved through good nutrition; of particular note are omega-3, antioxidants and plant sources of protein.”Emma Cannon
What Is The Best Olive Oil To Buy For Fertility?
It is important to ensure you buy the right Extra Virgin Olive Oil to ensure the highest possible quantity of these fabulous fertility boosting antioxidants in every drizzle.
But beware! – not all olive oil is the same. There are different grades of olive oil and associated standards are defined by the International Olive Council.
Extra virgin olive oil is the highest quality, best extra virgin olive oil you can get. To qualify as extra virgin olive oil, it is an olive oil of less than 0.8% acidity and has no taste defects. In practice, the very best extra virgin olive oils have acidity levels much lower. Morocco Gold extra virgin olive oil is consistently below 0.5%, normally around 0.25% to 0.3% depending on the weather conditions throughout the growing season.
Why Is Nutrition Important For Fertility?
According to the Olive Wellness Institute, nutrition can impact the health of the egg, the health of the sperm, the production of fertility hormones which impact the timing of ovulation, the health of the uterus (and consequently the likelihood of implantation), and the growth and development of the foetus.
There are 4 key stages of support that nutrition intervention is required.
- Try To Conceive
- Dietary Conditions
- Assisted Reproductive Treatments
Trying To Conceive
The first stage is couples who have just started trying to conceive. The key message for couples who are trying to conceive is the impact of nutrition to shape their baby’s future. Research suggests that preconception nutrition can influence genetic programming to impact a child’s future weight, risk of chronic diseases and cognitive abilities.
For example, a study by Dr Petry and colleagues suggests that pre-conception maternal and paternal lipid intake may impact genetic printing to influence the child’s future development and metabolism. Furthermore, a Mediterranean-style diet and monounsaturated fat intake during pregnancy has been linked to decreased cardiovascular disease risk for the baby later on in life.
Dietary conditions During Pregnancy
Stage two is for couples with pre-existing or newly diagnosed dietary conditions which increase the risk of infertility. Conditions include Poly Cystic Ovarian Syndrome, Endometriosis, Insulin Resistance, Inflammatory Bowel Disease, Thyroid conditions and more. Couples with dietary conditions need to be counselled that optimal dietary management may assist in improving fertility outcomes. For example, studies suggest that endometriosis may be improved with an anti-inflammatory type diet. Extra Virgin olive oil has been found to be beneficial for immune-inflammatory diseases such as Rheumatoid Arthritis and Inflammatory Bowel Disease and may also play a protective role in endometriosis.
Current studies suggest that a Mediterranean-diet style may be beneficial for clients with Poly Cystic Ovarian Syndrome.
Assisted Reproductive Treatments
The third stage of couples requiring nutrition intervention are those undergoing Assisted Reproductive Treatments (ART). ART includes a range of procedures such as ovulation induction for women who aren’t ovulating regularly, and artificial insemination, where semen is transferred directly into a woman’s uterus. Before moving onto In Vitro Fertilisation, solving problems utilising diet and lifestyle should be considered. For example, around 30% of fertility problems arise from male sperm health. Studies suggest that Extra Virgin olive oil may help to improve semen quality and sperm functionality which may improve ART outcomes.
Secondly, optimal egg health is essential for successful ART. Inflammation in the fluid surrounding the egg impacts egg quality and decreases the chance of conception. Studies show that Extra Virgin olive oil helps to minimise inflammation.
Thirdly, approximately half of all embryo implantations result in failed pregnancy. Although this can be caused by the health of the embryo, uterine receptivity is also an important factor.
Women require a thick uterine lining of at least 7milimeters for implantation. Studies suggest that vitamin E supplements may help to increase the thickness of the uterine lining, although the mechanism for this remains unknown. Extra Virgin olive oil is a rich dietary source of vitamin E, and although no studies have been conducted, it is plausible that the vitamin E in Extra Virgin olive oil may be one of the factors contributing to its benefit in women who are trying to conceive. Aspirin is often given to reduce inflammation. Studies show that Extra Virgin olive oil has significant anti-inflammatory effects.
In Vitro Fertilisation
Lastly, the final stage of nutrition intervention is for couples undergoing In Vitro Fertilisation (IVF). IVF literally means ‘fertilisation in a test tube’. The embryo is then transferred into the woman’s uterus. Studies suggest that adherence to a Mediterranean-style diet, including the use of Extra Virgin olive oil may strengthen IVF outcomes. For example a study by Dr Vujkovic and colleagues found that women consuming a more Mediterranean-style diet were more likely to become pregnant through IVF than those consuming a more ‘health conscious’ dietary style which was lower in healthy oils and legumes. In conclusion these results were substantiated by Dr Karayiannis and colleagues who found that a 5 point increase in the Mediterranean Diet Score resulted in a 2.7 times higher likelihood of pregnancy through IVF.
Furthermore, a diet high in Extra Virgin olive oil and fish, and low in meat, was found to improve embryonic growth and minimise risk of miscarriages.
In summary, current research suggests that Extra Virgin olive oil may be beneficial for fertility whether couples are trying to conceive naturally, have dietary conditions which may impact their fertility, are undergoing Assisted Reproductive Treatments or In Vitro Fertilisation.
Is Extra Virgin Olive Oil Safe During Pregnancy?
Before you add extra virgin olive oil to your pregnancy diet, you should know whether it is safe for you or not. Well, extra virgin olive oil is very safe for you to consume during your pregnancy and, thus, you may safely add it to your pregnancy diet. It has many benefits for a pregnant woman. In fact, it is not only good for the to-be-mommy but it also has immense benefits for the unborn baby too.
Benefits of Extra Virgin Olive Oil for Pregnant Women
Olives are power-packed with various health benefits. Apart from being rich in dietary fiber, olives are a rich source of monounsaturated fats, vitamin E, and iron. Extra virgin olive oil is very gentle on the stomach and, thus, very safe for consumption during pregnancy. Here’s how it helps you and your unborn baby during pregnancy.
Olive oil may not be a high source of vitamin E. However, because of its resistance to oxidation, the quantity present offers ample benefits to a pregnant woman. Vitamin E is one of the components that help your baby to adapt better in the oxygen-filled environment, soon after birth. If the mother of a premature or preterm baby consumes olive oil during the breastfeeding stage, it may help her baby to develop better.
Beneficial in Foetal Development:
If you consume olive oil during pregnancy it may greatly benefit the growth and development of your unborn baby. The substantial amounts of omega-3 fatty acids are extremely beneficial for your baby’s heart. It has also been observed that consumption of olive oil during pregnancy improves brain function and development and it also improves the learning skills of your baby, as he grows. Also, if a mother consumes olive oil on a regular basis during her pregnancy, it may positively impact the height and weight of her unborn baby.
Helps in Reducing Stretch Marks During Pregnancy:
Developing stretch marks is a very common phenomenon during pregnancy and most women may experience it. This may happen because as your baby grows, your pelvic muscles and abdomen stretch to accommodate your growing baby, which in turn may lead to stretch marks. Olive oil has been in use for a long time to overcome the problem of stretch marks during pregnancy. If you keep applying olive oil on your tummy area every day, it is possible that you may not have stretch marks during pregnancy. And even if you do develop stretch marks, they may either become light or in some cases, even disappear after regular usage. However, the only mantra that you need to follow while using olive oil for stretch marks during pregnancy is to use it on a regular basis.
Beneficial in Improving Reflexes in Babies:
It has been observed that mothers who consumed olive oil regularly during their pregnancy journey gave birth to babies who had better or improved psychomotor reflexes in comparison to women who did not consume olive oil during their pregnancy.
Helpful in Fighting Various Infections:
Pregnancy may make your immune system sluggish, and thus, may make pregnant women more susceptible to falling ill with various kinds of infections. However, including olive oil in your pregnancy diet may prove to be beneficial. This is because olive oil is a rich source of Vitamin A, which helps in building a strong immune system. This, in turn, may help in keeping various infections at bay. Also, Vitamin A is very beneficial for the eyes, and including olive oil in your pregnancy diet may not only ensure good eye-health of the would-be mother but it may also be beneficial for fetal eye development.
It is important to remember that olive oil, like any other oil, should be consumed in moderation. You may safely consume and apply olive oil on your skin during pregnancy but refrain from going overboard with its consumption and usage. In any case, we also suggest that you get a go-ahead from your doctor before doing so, especially if you’re using it for the first time. This is because every pregnancy is different and what may be beneficial and healthy for one woman may not be for the other. Thus your doctor may know what is best for you during your pregnancy.
Current research suggests that extra virgin olive oil may be beneficial for fertility whether couples are trying to conceive naturally, have dietary conditions which may impact their fertility, are undergoing Assisted Reproductive Treatments or In Vitro Fertilisation.
