If you're deep in IVF prep, you've probably heard the phrase "eat clean for fertility" more times than you can count. But what does that actually mean when your hormones are doing backflips and your future baby depends on your IVF diet?
In just six simple steps, you can learn the IVF foods to avoid so you can feel confident about what you’re putting on your plate and how it supports your embryo transfer. It’s not about being perfect. It’s about giving your body the best shot at success.
1. Added Sugar & Refined Carbs
The sugar crash is real, and it’s not just about your energy. Refined carbs and added sugar can spike your insulin and jack up your hormone balance. That’s a hard no during IVF. If you’re looking for a challenge, start a no-added-sugar streak now and thank yourself later.
2. Caffeine
I love my morning coffee as much as anyone, but IVF isn’t the time to overdo it. Stick to under 200 mg a day (think: one small cup of coffee or a matcha latte). High caffeine levels may interfere with fertility, and honestly, your adrenals need a break, too.
3. Alcohol
Just say nope. I know, it’s a buzzkill, but alcohol messes with estrogen levels and can impact implantation. If you're serious about optimizing your IVF diet, treat alcohol like an ex you don’t text anymore.
4. Trans Fats & Processed Junk
Inflammation is the enemy right now. Processed foods (those sneaky snacks and fast food staples) and trans fats can interfere with egg quality and implantation. Keep your meals clean and colorful. Shop the perimeter of the grocery store and read your labels.
5. High-Mercury Fish
Fish is great for protein and omega-3s, but not all fish is created equal. Skip tuna, swordfish, and king mackerel. Mercury builds up in the body and can be toxic to reproductive health. Stick with low-mercury options like salmon or sardines instead.
6. Soy (in excess)
Soy isn’t the devil, but during IVF diets, it deserves a little side-eye. Soy contains phytoestrogens, which mimic estrogen in your body. And when your hormones are already being managed medically, it’s best not to throw in wildcards. A little tofu? Fine. A soy latte every morning? Maybe not.
What to Remember About Your IVF Diet
Your body is working hard right now, so the goal isn’t restriction—it’s support. Focus on whole foods, limit anything that could mess with your hormones, and stay consistent with what feels good and nourishing.
Every smart choice you make is a step toward a healthy transfer and, hopefully, a positive test. You've got this.
