4 Foods You Should Avoid Now If You Want to Get Pregnant Later

These days, it seems like almost anything can mess with your fertility, including everyday habits like staring at your smartphone and over-stressing. But can what you eat now affect your fertility—even if you don't anticipate getting pregnant anytime soon?  Cross these items off of your grocery list now to avoid having issues getting knocked up in the future.
Trans Fats
Trans fats—also known as damaged, hydrogenated, or partially hydrogenated fats—are commonly found in processed or fried foods, processed oils, and some margarines. It's smart to cut them out completely since they can prevent your body from making use of essential fats. Products labeled "low-fat" should also be avoided since they often contain added trans fats, sugar, and sweeteners. In fact, in one large-scale study published in the journal Human Reproduction, women who ate two or more low-fat dairy products a day were twice as likely to have problems conceiving. Stick to foods rich in monounsaturated fats instead, such as olive oil, avocados, peanuts, and organic, free-range poultry.

Refined Carbohydrates
These are bad for your fertility (and general health) since they release sugars into your bloodstream too quickly, causing your pancreas to rapidly release the hormone insulin. In women, this leads to increased production of the hormone testosterone—and this resulting hormone imbalance can affect ovulation, says West. For optimal ovulation, replace refined carbs with complex carbohydrates like beans, vegetables, whole grains, berries, and citrus fruits. They're more nutritionally dense and help keep blood-sugar levels stable.

Alcoholic and Caffeinated Drinks
What do these beverages have in common? They're both highly acidic and can cause major baby-making roadblocks when consumed in excess. While your body naturally produces acid, alcoholic and caffeinated drinks (and foods like red meat and dried fruits) can significantly increase your body's overall acidity; this can strain your liver and kidneys and result in toxicity that depletes your body of nutrients vital to reproduction. These highly acidic products also throw off your body's acid-alkaline balance, which is problematic since sperm thrive in a slightly alkaline environment. For optimal fertility, be sure to avoid highly acidic foods and drinks and up your intake of alkaline foods like sea vegetables, most fruits and veggies, apple cider vinegar, coconut water, and oils such as avocado, olive, coconut, and flaxseed oil.
Swordfish
Eating large fish like swordfish, tuna, or shark more than once a week can increase the toxins in your body, which in turn messes with your hormone regulation, cholesterol levels, blood-sugar balance, and digestion. Since all of these need to be stable to preserve fertility, your best bet is to stick with smaller fish—or at least limit your intake of these varieties.
