How you nourish your body is key not only when you have a baby in your belly, but also to help prepare for pregnancy. Have you heard that there are some foods linked to better female fertility? Pro-fertility diets have been quite the hot topic lately as more and more studies show the impact of nutrition on reproductive health.
Here’s the lowdown on foods that increase fertility in females (plus which foods you should avoid) to naturally boost your chances of getting pregnant.
Fertility Foods: What foods increase female fertility?
Plant-based protein Plant-based diets are all the rage these days. And evidence points to benefits for moms-to-be too. Scientists have found that replacing meat with vegetable sources of protein may reduce the risk of ovulatory infertility by up to 50%! You don’t need to become a vegetarian tomorrow or anything like that, but consider swapping out some meat with beans, lentils, chickpeas, edamame, tofu, oats, nuts, and seeds.
Leafy green veggies Spinach, romaine lettuce, asparagus, Brussels sprouts, and broccoli are high in folate, an important nutrient for pre-conception and pregnancy. They also pack a decent protein punch.
Fruit Fruit is another important part of the fertility diet for women. A 2018 study found that people who ate at least 3 portions of fruit per day got pregnant faster and had higher fertility. Consider adding berries to your breakfast as they are loaded with antioxidants which help protect cells from aging (including your eggs).
Seafood Fish high in omega-3 fatty acids and low in mercury such as sardines, cod, salmon, and herring can up your chances of conceiving. Other research shows that eating more fish is linked to higher chances of a live birth following infertility treatment. Eat other types of seafood like oysters as well. Not only are they a known aphrodisiac, but they contain zinc, two things important for conception!
Unsaturated fats “Good” fats like the ones in olive oil, avocado, nuts and seeds are linked to better fertility.
Full-fat dairy Some researchers have found that high-fat dairy is connected to lower rates of ovulation infertility. Take this one with a grain of salt, however, because the evidence on dairy is a bit mixed.
Whole grains If you have the choice between white or whole-wheat bread, go for the ladder. A 2016 study found that people undergoing IVF treatment who ate more whole grains, such as brown rice, quinoa, and whole oats, were significantly more likely to have a live birth. Researchers believe this is because whole grains thicken the endometrial layer, making implantation more likely.
Vitamins Lastly, make sure you’re getting all the vitamins and nutrients you need. Data suggests that vitamin D may be important for fertility, especially for women using artificial reproductive technology and those with Polycystic Ovary Syndrome. Current guidelines recommend taking vitamin D supplements during winter, and all women trying to conceive should take a prenatal supplement containing 400mg of folate. Iron and zinc are two more key nutrients for fertility.
Of course, it’s possible to get pregnant regardless of what you eat. Some studies may have trouble proving a cause-effect link between foods and fertility because there are so many other factors at play: smoking, sleep, exercise, and weight are all big influences. There are exceptions too, like my obese neighbor who eats meat three times per day and conceived on her second cycle after stopping the pill. But if you’re looking to up your chances of getting pregnant and prepare your body for a healthy pregnancy, research shows these are the foods to add to your plate.
Now let’s take a look at what scientists say you should steer clear of when trying to get pregnant.
What foods to avoid when you’re trying to get pregnant fast
Fast food, trans and saturated fats Who doesn’t love indulging on fries or sweets from time to time? Just watch how much you eat. The fats in microwave popcorn, frozen pizza, fried foods, packaged cakes and cookies, and refrigerated dough are just bad news for your health, even if you’re not trying to get pregnant. Researchers discovered that eating fast food up to 2 times per week or not at all corresponds to a 34% and 41% reduced risk of infertility, respectively.
Sugary drinks If you’re an avid soda drinker, you may want to switch to diet. Several studies have found that sugar-sweetened drinks reduce fertility.
Refined carbs Evidence shows that a diet with a lot of refined carbohydrates, such as those found in white bread, white rice, sugary cereals, pastries, and pizza, hurts female fertility.
Alcohol Even before you get pregnant, be mindful of alcohol. Heavy drinking is linked to a higher risk of ovulation disorders and can diminish the ovarian reserve. Evidence also shows that even moderate drinking decreases the success rate of infertility treatments like IVF. Because doctors have yet to determine a “safe dose” of alcohol for a growing baby, it’s generally recommended to avoid drinking all together before conception and during pregnancy.
Caffeine Some studies found that women who have a lot of caffeine take longer to conceive and have a higher risk of miscarriage. To be safe, doctors advise women to limit caffeine before conception and during pregnancy to 200 milligrams per day, which is about two cups of coffee.
Adding more fresh, non-processed foods to your daily meals is not only better for health all-around, but evidence shows promising benefits for reproductive health too. So keep this list in mind of foods that increase fertility in females when doing your weekly grocery shopping. Note that it takes about three months for an ovulated egg to mature, so it will take a little while to see results from changes to your eating habits. The bottom line is, that if you take good care of your body with a balanced diet of nutritious foods, you’re more likely to conceive and have a healthy baby.
