When you are ready to start a family, following a healthy pre-pregnancy diet and lifestyle is one of the most important things that you can do. The goal is to increase your fertility and prepare yourself for a healthy pregnancy.
With all the information available, it can be confusing and even frustrating trying to figure out what pre-pregnancy diet and lifestyle tips are most important. How do you get the best information and avoid becoming overwhelmed?
In this article, we share the top ten pre-pregnancy diet and lifestyle tips. As always, please check with your healthcare provider before making any changes to your health plan.
1. Eat a healthful, pre-pregnancy diet.
Diet and lifestyle choices can have a significant impact on your fertility. Eating well and developing healthy habits is important before and during pregnancy.
A large study conducted by Harvard researchers showed that women who adhered to a combination of five or more lifestyle factors, including specific changes to their diets, were at a 69% lower risk of ovulatory disorder infertility.
The following diet and lifestyle factors from the Fertility Diet will help you follow a healthy pre-pregnancy diet.
Increase the amount of “good” fats in your diet.
Monounsaturated fats are often known as “good fats.” Eat more avocados, nuts, and seeds, and use olive oil and canola oil for cooking and in salad dressings.
Limit foods containing trans fats.
Examples of these types of foods include vegetable shortenings, some kinds of margarine, baked goods, pie crusts, frostings, and fried foods. Check the Nutrition Facts Panel for trans fats. You can also check the ingredients list for “hydrogenated” or “partially hydrogenated” vegetable oil.
Choose low glycemic index (GI) and glycemic load (GL) carbohydrates.
These foods include dried beans, legumes, fresh fruits, 100% whole-grain bread, oatmeal, quinoa, and non-starchy vegetables. The GI is a measure of how much and how quickly a carbohydrate-containing food increases blood sugar and insulin levels. Foods are ranked on a scale of 1-100. In general, eating foods with a low GI (<55) results in a slower rise in blood sugar levels and less insulin secretion.
The glycemic index alone cannot tell the entire story. The GL also needs to be considered to get an accurate understanding of a food’s total effect on blood sugar. A Harvard Health article explains this in more detail and provides a list of foods according to GI and GL
In general, limit processed carbohydrates such as white rice, bread, and pasta, and most crackers, chips, cookies, and other packaged foods. This is beneficial for any woman trying to conceive, and especially important if you have PCOS (Polycystic Ovarian Syndrome).
Eat more vegetarian sources of iron.
Good vegetarian sources of iron include spinach, beans, legumes, prunes, and cashews.
Choose full-fat dairy
Examples include whole milk, full-fat yogurt, or cheese. Women who ate full-fat dairy at least once a day decreased their risk of ovulatory infertility by 27% compared to those who rarely ate full-fat dairy.
2. Achieve or maintain a healthy body weight.
Being overweight or underweight stresses the body. This disturbs hormone production, interrupts normal menstrual cycles, and impairs ovulation and fertility.
Research indicates that if you are overweight or obese, it will take you longer to conceive, and you are at a higher risk of miscarriage than normal-weight women.
Losing weight before pregnancy may improve fertility and reduce the risk of pregnancy complications such as preterm birth, gestational diabetes, preeclampsia (very high blood pressure during pregnancy), and certain birth defects. Also, fertility treatment is generally more successful in women who are not obese.
The best weight range for fertility seems to be a Body Mass Index (BMI) of 20 to 24.
3. Get active.
Moderate physical activity is best while trying to get fit for pregnancy. Studies show that if you are overweight or obese, adding any physical activity improves your chances of conceiving.
Regular physical activity increases metabolism and optimizes your reproductive system. Exercise stimulates the endocrine glands, which release hormones that help egg production and maturation. Exercise also decreases stress, an added benefit for fertility.
If you are underweight or normal weight, too much vigorous activity may increase the time it takes you to conceive. In one study, when women switched from vigorous to moderate activity, their fertility improved. For some women, more than an hour of vigorous exercise a day can lead to a decrease in the production of the hormones that stimulate ovarian function. This affects egg production, fertility, and the risk of miscarriage.
Too much or too little exercise can be detrimental to fertility and a healthy pregnancy. The goal is to find the right balance to optimize your reproductive function. In general, 30-60 minutes of moderate exercise is recommended on most days of the week.
4. Take a high-quality preconception prenatal vitamin.
Start taking a good preconception prenatal vitamin as soon as you start trying to conceive. As Shady Grove Fertility explains, a woman’s nutrient needs are different while trying to conceive than during pregnancy.
A preconception vitamin should provide a complete range of nutrients, including folate, choline, iodine, iron, and vitamin D.
Folate and choline are essential for the early development of the baby’s neural tube, which occurs during the first several weeks of pregnancy, often before you know you are pregnant. Maintaining a healthy vitamin D level is also essential for fertility and a healthy pregnancy.
5. Consider other preconception supplements.
Depending on your age and health history, taking certain nutrients in addition to your prenatal may support healthy egg quality a healthy pregnancy.
Coenzyme Q10 (CoQ10)
If you are over 35, you may want to consider taking a CoQ10 supplement. CoQ10 plays a crucial role in energy production in the body’s cells, including egg cells.
As you age, your cells make less CoQ10 and are less efficient at producing energy. Egg cells are the largest cells in the human body and require a lot of energy to mature properly.
Maintaining healthy egg quality is one of the most important factors in supporting fertility as you age. Research indicates that a diet high in CoQ10can support healthy egg quality and a healthy pregnancy.
Vitamin D is a fat-soluble vitamin produced in your skin cells in response to sun exposure. If you are in the sun enough, at the right time of year, you will make all the vitamin D you need.
Most people don’t get enough sun exposure to maintain adequate vitamin D levels. Our diets don’t provide enough vitamin D, either. Few foods naturally contain a significant amount of vitamin D.
Getting enough vitamin D to achieve an optimal vitamin D blood level is important before and during pregnancy. Several studies suggest that vitamin D blood levels of 30 ng/mL or higher help support a healthy pregnancy.
It is important to have your vitamin D level checked when you start trying to conceive. If your vitamin D level is below 30 ng/dl, you may consider taking 50-100 mcg (2,000-4,000 IU) of vitamin D3 for a few months to restore you to a healthy level. Once you’ve achieved a healthy level, most people can switch to a maintenance dose of 50 mcg (2,000 IU) of vitamin D3 per day.
Typical prenatal vitamins provide only 10-25 mcg (400-1,000 IU) of vitamin D, which may not be enough for most women. Higher doses (50-100 mcg or 2,000-4,000 IU per day) of vitamin D are safe during pregnancy and are effective in achieving healthy vitamin D levels.
Inositol is a B-vitamin-like nutrient naturally found in whole grains, beans, nuts, and fruits.
Research suggests that inositols can support healthy blood glucose levels, menstrual cycles, and ovarian function in women.
Inositol can also promote healthy egg quality and can be helpful while trying to become pregnant. Studies indicate that inositol benefits women by supporting a healthy response to fertility treatment.
There are many different forms of inositol. The two types that have shown benefit in research studies are myo-inositol and D-chiro-inositol.
6. Limit caffeine and alcohol.
Both caffeine and alcohol may reduce your fertility.
Caffeine is a well-known stimulant found in coffee, tea, chocolate, soda, and energy drinks. Most women know that limiting caffeine is important during pregnancy, but what about before getting pregnant? Can having your daily coffee affect your chances of conceiving?
The answer is yes, but it depends on how much caffeine you’re consuming. Studies show that as little as 200 mg of caffeine daily (less than the 260 mg in an eight-ounce Starbucks® brewed coffee) can decrease your chance of conception and increase your risk of miscarriage.
Other studies have shown that caffeine lengthens the time it takes to get pregnant.
Dr. Samuel Pauli explains caffeine’s potential effect on fertility and lists the amount of caffeine in common beverages and foods. So yes, you can still have a small cup of coffee or cappuccino daily. But, be sure to limit your caffeine intake to less than 200 mg a day when preparing for pregnancy.
Although the research is mixed, drinking alcohol may delay the amount of time it takes to get pregnant.
A recent (2016) Danish study showed that 1-2 servings of alcohol per day had no effect on fertility among over 6,000 women trying to conceive naturally (without fertility treatment).
Shady Grove Fertility summarizes earlier research on the impact of alcohol in women undergoing fertility treatment. When compared to women who did not drink, fertility decreased slightly in women who had up to 5 drinks per week and fell further in those who had over 10 drinks per week.
Another study showed that women going through IVF who drank more than 6 drinks per week were 18% less likely to get pregnant.
The bottom line is to decrease the amount of alcohol you drink while trying to conceive. This is especially important if you are going through fertility treatment. If you might be pregnant, do not drink.
7. Stop smoking.
If you smoke, stop before you start trying to conceive. Smoking is not only harmful to your health, but it is also harmful to your fertility. Smoking cigarettes increases the time it takes to get pregnant. If you get pregnant, smoking increases the risk of miscarriage and birth defects.
See your healthcare provider if you need help quitting, or refer to the American Cancer Society’s guide to quitting smoking.
8. Reduce stress.
As Dr. Alice Domar explained, we don’t know for sure whether stress causes infertility, but we are aware that infertility causes stress.
The connection between stress and fertility isn’t entirely clear. Studies indicate that pregnancy is more likely to occur during months when couples report feeling relaxed, and less likely during months, they report more anxiety.
Dr. Allen Morgan explains that practicing stress management techniques helps some women get pregnant who were not successful before. Acupuncture, massage therapy, exercise, meditation, and deep breathing techniques show promise in decreasing stress.
9. Get enough sleep.
More than one-third of Americans don’t get enough sleep, according to the Centers for Disease Control.
Adequate sleep is important for your health, your fertility, and for a healthy pregnancy.
During sleep, our bodies go into repair and restore mode. Getting enough shut-eye is necessary for repairing cells, regulating hormones, and many other body processes.
Sleep is important for regulating hormones involved in ovulation and reproduction (leptin, progesterone, estrogen, luteinizing hormone, and follicle-stimulating hormone). Sleep deprivation can disrupt your hormonal balance, resulting in irregular menstruation and ovulation. This may mean it takes you longer to conceive.
Aim to sleep 7-9 hours per night, most nights of the week.
10. Seek medical care for untreated conditions.
Certain medical conditions harm fertility and pregnancy. It is important to see a gynecologist or primary care physician for a physical before trying to conceive or starting fertility treatments. Getting treatment for a previously undiagnosed condition can improve your fertility and help you prepare for pregnancy.
In summary, eat a healthy pre-pregnancy diet, exercise moderately, take the right supplements, take a pre-conception prenatal, and make other lifestyle changes to get fit for pregnancy. Try to incorporate these diet and lifestyle habits into your daily routine.
