There is a reason these specific foods should be avoiding during a preconception time, and if you are serious about conceiving, you should definitely leave them out of your plate - Meat, eggs and dairy products: either go organic or leave them out. Absolutely every animal product that you buy in a store (except if you are buying organic) is filled with hormones.
Meat, eggs and dairy products are nutritious, but the problem is today s commercial meat and dairy farmers give the animals abnormal amounts of hormones in order to grow bigger and grow faster, produce more milk, more eggs etc. Some of these hormones mimic female hormone estrogen and disrupt your reproductive system. In my opinion going vegan is not the solution, because there are pesticides on the food you buy, but going organic (and/or organic vegan) would be the right answer.
Raw or undercooked eggs, meats, or fish or unpasteurized cheeses, because eating raw or undercooked food could put you at risk for salmonella, listeria, or other food-borne bacteria.
Swordfish, tilefish, shark, or king mackerel are all fish known to be high in mercury. Mercury can accumulate and linger in your body long after you consume it, which can be harmful to you and can damage your baby s developing nervous system. If you love fish, avoid the big and oily fish and stick to smaller varieties like flounder, haddock, trout, salmon, and shrimp.
Soy is not a miracle food, and this is especially not true if soy is labeled and non-organic, which would mean it is GMO. But this is not the only reason you should avoid soy if you are trying to conceive. Soy contains phytoestrogens that are naturally derived estrogens, so they mimic the estrogen in your body. For example, countries where consumption of soy is higher than average (for example Japan, China) do not have problems with decreased fertility, which is a proof soy does not have negative effect if consumed in normal amounts. Some studies have found that large quantities of soy protein can inhibit fertility, but ff you like munching on a few edamame now and then, that s OK. But if you are experiencing infertility problems, it should help droping the soy milk, tofu, and tempeh from your diet.
Fresh produce is unfortunately also on the list. The main reasons are commercial farms that use too much chemicals and pesticides. Either go organic, or avoid especially the following: apricots, apples, celery, cucumbers, green beans, grapes, strawberries, bell peppers, spinach, cherries, peaches, cantaloupe (Mexican)
Alcohol and babies don t mix, and alcohol does inhibit both male and female s ability to conceive.
Caffeine: take it easy with coffee and caffeined products.
