If you’re looking to conceive soon, nutrition can have a big impact on your fertility and reproductive health—both positive and negative. Get to know which foods are natural fertility boosters and valuable lifestyle changes that can improve your journey to conception. Quick facts: Why are diet and nutrition important for fertility? As the saying goes, we really are what we eat. Our diets and nutrition impact almost all of our body’s processes—all the way from our metabolism to our mental health. But one often overlooked area is how food can impact our fertility. When trying to conceive, you’ll need a high-nutritional diet. This can increase your chances of conceiving and help to create a healthy home for your baby during their vital first 9 months. Even making small changes to your lifestyle and nutrition choices can go a long way. Here are 16 evidence-backed tips from our Registered Nurse and Associate Nutritionist, Emily Moreton to help prepare your body for pregnancy. You can also book an appointment with a Hertility Nutritionist for a personalised plan. 1. Follow a Mediterranean-style diet Whilst there are no specific guidelines for a recommended fertility diet, the Mediterranean diet, is associated with improved fertility in both women and men. Known for its abundance of fruits, vegetables, nuts, whole grains, fish and healthy fats, the Mediterranean diet is rich in antioxidants. These have been shown to protect sperm and eggs from DNA damage and oxidative stress. A study involving 15,396 participants, which looked at how different diets affect fertility, showed that sticking to the Mediterranean diet improved birth and pregnancy rates significantly, with a 91% higher chance of success. This diet is also high in fibre and rich in vitamins and minerals that support fertility and pregnancy. Think lots of veg, whole grains, nuts, seeds, beans, pulses, olive oils, avocados and oily fish. 2. Eats foods high in antioxidants Eating a diet rich in a variety of colourful fruits and vegetables can provide a wide range of antioxidants that support fertility and overall health. Think making a rainbow on your plate. Foods high in antioxidants include fruits (such as berries, apples, and citrus fruits), vegetables (such as broccoli, spinach, kale, and carrots), nuts, seeds, and whole grains. 3. Increase intake of plant-based proteins In general, you should focus on lowering your intake of red and processed animal meats and focus on adding plant-based protein sources into your diet.  This can include fertility-friendly and micronutrient-rich beans, lentils, peas, soya beans, and chickpeas. Plant-based protein sources help to support healthy ovulation and are high in antioxidants and nutrients, such as iron and fibre, which are really important during pregnancy.  Low iron levels can add to your tiredness or even could cause iron deficiency anaemia. Iron deficiency during pregnancy can increase the risk of pregnancy complications. It is also important to keep your iron uptake up postpartum too, to replace any iron lost at birth.  You’ll also find some protein in whole grains such as quinoa. If you are opting for plant-based meat alternatives (‘fake meats’), choose a brand that is not ultra-processed and low in additives. 4. Cut down on sugar Cutting down on sugar can be beneficial for fertility. This is because too much sugar can lead to insulin sensitivity, disrupting certain reproductive hormones and causing inflammation. Insulin spikes have been associated with poor egg quality and sperm production and could affect implantation. A study published in the American Journal of Clinical Nutrition in 2018 found that women who consumed two or more servings of sugary drinks per day had a 50% higher risk of ovulatory infertility compared to those who consumed less than one serving per month. Reducing sugar intake and opting for a balanced, low-glycemic index diet can help improve insulin sensitivity and overall reproductive health. Limit sugary foods and high glycemic index foods such as cakes, biscuits, fizzy drinks, energy drinks, sweets, white rice and white bread. Check the labels for high sugar content. 5. Take pregnancy supplements Folic acid Folic acid is an important supplement during pregnancy because it decreases a risk called neural tube defects. This is a defect that can occur during the development of the baby’s brain and spine.  If you are currently trying to become pregnant, it is advised to take at least 400 mcg of folic acid supplement every day for 12 weeks before conception and for at least three months after conceiving. Some people are at an increased risk of their baby having a neural tube defect and so it is advisable to speak with your doctor as they may recommend and prescribe you a higher dose.  Prenatal vitamins Prenatal vitamins typically contain a combination of various vitamins and minerals that are important for both maternal and foetal health. While folic acid is a main component of prenatal vitamins, these vitamins usually contain a range of other nutrients as well.  These include iron, calcium, vitamin D and other essential vitamins and minerals needed to support maternal health and the baby’s development during pregnancy. Tip: More often than not, doctors will suggest taking prenatal vitamins instead of just folic acid supplements because they cover a wider range of needs for both mum and baby’s health. However, it’s essential to consult with your doctor to determine the most appropriate approach for your unique needs.  6. Take Vitamin D for pregnancy  A previous study has shown that both men’s and women’s vitamin D levels impact fertility and IVF results. It showed that Vitamin D supplements reduce risks for mums and babies, might prevent bone problems, and play a role in foetal development.  How much Vitamin D should I take? It’s recommended that all adults at all stages of life should supplement with 10 micrograms a day of Vitamin D, in the UK. This is particularly true if you are trying to conceive, or you are pregnant—so be sure to supplement right through from the preconception period to breastfeeding.  Prenatal vitamins often contain vitamin D, but the amount can vary […]

When our reproductive hormone levels are affected, it can cause menstrual cycle disruptions that can result in fertility issues. In this article, we’ll take a look at alcohol’s effects on the main female reproductive hormones. Quick facts: How alcohol and hormones interact According to recent data, women and those assigned-female-at-birth are, on average, drinking more alcohol than ever before. Whilst many people are aware of the immediate health consequences of drinking—including the caloric impact and the dreaded hangover, there’s still very limited awareness of the effects that alcohol can have on female hormonal health.  Hormones act as chemical messengers, which control and coordinate various bodily processes. Each of our hormones relies on a complex system of interactions, often with other hormones, to maintain their levels and carry out their intended functions.  Drinking alcohol, as well as other lifestyle factors like smoking, can affect our hormones, both directly and indirectly. Which hormones are affected by alcohol? Hormones affected by alcohol include: Our hormones are sensitive. They rely on a complex set of interactions, both with one another and other bodily processes in order to stay in balance and perform their functions properly.  Alcohol consumption is known to affect our levels of oestrogen, progesterone and testosterone significantly—three very important hormones in the regulation of the menstrual cycle and overall health. It can also affect our levels of Anti-müllerian Hormone (AMH), gonadotropins like Follicle stimulating hormone (FSH) and Lutenising hormone (LH), thyroid hormones and prolactin.  Let’s take a look at each of them in turn. Oestrogen and alcohol Oestrogen is probably the hormone you know best—it plays an important role in many elements of our health, including the regulation of the menstrual cycle, maintaining bone density and skin health. Acute consumption of alcohol has been shown to increase oestrogen levels. Increased oestrogen levels over a prolonged period can be associated with breast cancer development in those assigned-female-at-birth. The United Kingdom Million Women Study revealed that every additional drink per day contributed to 11 breast cancers per 1,000 women up to age 75. Progesterone and alcohol Follicle-stimulating hormone (FSH) and luteinising hormone (LH), are involved in egg maturation and ovulation, two key elements of the menstrual cycle and female fertility. A surge in your levels of LH triggers the egg to be ovulated, however, there is some evidence that alcohol consumption may affect both the levels of LH in general and the ability of the egg to respond to LH. Excessive alcohol consumption may even affect how the cells within the fallopian tubes function. Testosterone and alcohol Testosterone is typically associated with male sexual development and fertility, but it also plays an important role in female sexual development and fertility, including regulating female libido.  There is some evidence that moderate alcohol consumption may increase testosterone levels, causing an imbalance in androgen levels. High testosterone levels can lead to symptoms like acne, excessive facial and body hair growth (hirsutism), irregular periods, mood changes and loss of libido. Anti-Mullerian Hormone (AMH) and alcohol AMH is produced by the granulosa cells within your ovarian follicles and is used as an indicator of ovarian reserve (your egg count). The relationship between alcohol consumption and AMH is slightly contentious. Some studies have found no change in AMH levels in people who consumed alcohol but more recent studies have shown those who engage in “binge drinking” had lower levels of AMH.  Binge drinking is defined by the Centres for disease control (CDC) as “a pattern of drinking that brings a person’s blood alcohol concentration (BAC) to 0.08 g/dl or above”. Basically, consuming 4 or more drinks in the space of 2 hours.  Because of AMH’s close ties to your ovarian reserve, lowered AMH levels can indicate a low ovarian reserve. Gonadotropins and alcohol There are two types of gonadotropin hormones in the body—Follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Both FSH and LH are involved in egg maturation and ovulation, two key elements of the menstrual cycle and female fertility.  A surge in LH levels at the midpoint of the menstrual cycle is what triggers ovulation—that month’s mature egg being released into the Fallopian tube.  There is some evidence that suggests alcohol consumption may increase LH levels in general and also impair the ability of our eggs to respond to LH. Excessive alcohol consumption may also affect how the cells within the Fallopian tubes function. Thyroid hormones and alcohol Your thyroid is a butterfly-shaped gland that plays an important role in the regulation of many different bodily functions such as your heart rate, body temperature and growth development.  Alcohol consumption has been shown to alter the levels of the thyroid hormones, thyroid-stimulating hormone (TSH), thyroxine (T4) and triiodothyronine (T3) with heavy use showing decreased levels of T3 and T4. Low levels of thyroid hormones are known as hypothyroidism and can cause a huge number of symptoms including fatigue, weight gain, heavy or irregular periods, fertility issues and irregular ovulation, depression and more. Prolactin and alcohol Chronic alcohol consumption is associated with increased prolactin levels. Consistently high levels of prolactin in your body is called hyperprolactinemia and is significantly associated with infertility through interference with other hormones such as oestrogen and progesterone. Alcohol and trying to conceive When trying to conceive, cutting down on your drinking is often one of the first things on your preconception to-do list. The dangerous effects of alcohol on the developing foetus can range from physical to mental and generally disrupt their development in the womb (see foetal alcohol syndrome).  It is also known that alcohol consumption affects the success of IVF treatment, with one study showing people who had at least four drinks per week were 16% less likely to have a live birth than those who had less than four drinks. Additionally, a 21% lower live birth rate was found for couples in which both drank more than four drinks per week. Other effects of alcohol on the body As well as impacting our hormones, alcohol has other broad-reaching effects on the body and the […]

Folic acid is a vital preconception supplement. But what makes folic acid so important? How and when should you be taking it? We’ve broken down everything you need to know about folic acid for preconception care. Read on to get clued up. Quick facts: What is folic acid?  Folic acid is the man-made version of the vitamin folate, a form of vitamin B9. It is used by our bodies to make new cells and is needed to support the rapid growth of foetal tissues and organs in early pregnancy.  Unfortunately, our bodies do not store folic acid, which is why we must get our supply from certain foods and supplements. Why is folic acid important for pre-conception and pregnancy? Folic acid is important in helping your unborn child’s brain, skull and spinal cord to develop properly. It reduces the risk of potential neural tube defects, such as spina bifida, by 70%.  Whilst spina bifida is not that common, it can create significant problems for its sufferers that affect everyday life. These include problems with mobility and movement, bladder and bowel problems and learning difficulties.  Folic acid is also used to: When should you start taking folic acid? The advised amount of folic acid to take daily is 400mcg. However, some people may need a higher dose if they have a higher risk of having a pregnancy affected by neural tube defects.  You may have a higher risk if:  In these cases, your doctor will be able to advise the correct dosage you should be consuming to keep your child protected. Which foods contain natural forms of folic acid? You can also find the natural form of folic acid or folate, in certain foods. Introducing these to your diet will increase your folate levels: However, the amount of folic acid in these foods is often not enough to provide your baby with the best protection, so it is important to add the tablet form to your daily routine too.
