11 Fall Foods That Can Naturally Improve Fertility, from a Clinical Expert

“Diet is a first-principles lever for fertility since it influences inflammation, immune regulation, and hormone function,” says Rachel Swanson, MS, RD, LDN, a registered dietitian and author of the upcoming book Trying!: A Science-Backed Plan to Optimize Your Fertility. She adds that making wise nutritional choices is the key to optimizing the body’s receptivity for both pregnancy and long-term reproductive health.

Fall foods are some of the best to optimize your fertility, and early nightfall can pose some advantages, too. Melatonin is a big player for consistent bedtimes, natural light in the morning, and meals anchored to daylight.

Swanson says following the “24-hour fertility circuit” can support “trying” amid darker days:

• Morning – Light exposure + protein-rich breakfast (resets cortisol and reproductive hormones): Natural light (or a lightbox as a last resort) to cue your brain to regulate cortisol and reproductive hormone timing naturally.
• Midday – “Hormone harmony walk” + balanced lunch: A 10- to 15-minute stroll after lunch helps regulate blood sugar and cortisol, which directly influence ovulation quality. It also exposes you to natural light, reinforcing your body’s daytime signal.
• Evening – Early, dimly lit dinner + melatonin-producing foods: If you’re feeling drowsy earlier, lean into it. Shorter days trigger a small natural rise in melatonin and prolactin, helping the reproductive system conserve energy. Lean into it: rest supports hormone regulation more than pushing through fatigue.

Ahead, Swanson explains which foods you shouldn’t skip if you’re trying to boost your reproductive health—some of which may already be in your pantry or refrigerator. Plus, she shares one fall-inspired, meal-prep-friendly recipe that’s full of good-for-you ingredients—and it just might become a new fall healthy comfort favorite.

Top fall fertility food recommendations

The best fall foods to support fertility are those that promote metabolic health (helping maintain a healthy body composition, blood sugar, and insulin balance) and support the gut microbiome, according to Swanson. While food choices should always be personalized, aim to eat a wide variety of deeply pigmented, seasonal fruits and vegetables.

“Diversity is key,” Swanson says. “Fall examples include dark leafy greens, cruciferous vegetables, citrus fruits, winter squash, and carrots.” She also points out that leafy greens and beets, in particular, contain folate, which can support egg health.

Additionally, Swanson recommends the following list of foods as part of a balanced, anti-inflammatory fertility diet plan:

Pumpkin and sweet potato

For pumpkin and sweet potato, Swanson says the benefits come in the form of magnesium and complex carbs, which in turn can boost serotonin and melatonin.

Additionally, pumpkin seeds also contain zinc, which plays a role in DNA synthesis, cell division, early fetal development, egg production, and sperm production, according to experts at Utah State University. Zinc is also vital in making sure eggs are in the best state for fertilization during ovulation, says 2021 research published in the Biology of Reproduction journal.

On the other hand, sweet potatoes are rich in beta-carotene, which converts to vitamin A, an essential vitamin for healthy embryo development, according to past research published in The Journal of Nutrition.

Cinnamon, turmeric, and non-starchy vegetables

Swanson recommends cinnamon, turmeric, and non-starchy vegetables (such as cruciferous vegetables like broccoli) because they can help regulate blood sugar and insulin, thus improving cycle balance. She highlights that non-starchy veggies “are foundational for glycemic management, and these benefits are attributed to both the fiber content and the bioactive compounds these foods contain.”

Tart cherries, nuts, oats, and bananas

Tart cherries, walnuts, pistachios, oats, and bananas all get a thumbs-up from Swanson due to their naturally produced melatonin. “A small bowl of tart cherries and oats or a warm pistachio milk latte in the evening can signal your body that nighttime and hormone repair has begun,” she says.

Bananas are also a powerhouse of nutrients for fertility, containing magnesium, folate, and vitamin B6. According to nutrition experts at Utah State University and 2025 research published in the Nursing Research and Practice journal, all of these nutrients have a distinct purpose:

• Vitamin B6 can improve egg quality.
• Folate can help prevent birth defects like spina bifida.
• Magnesium can help fertilized eggs attach to the womb.

Sardines and mackerel

If you’re looking to support both your mood and mindset while trying, sardines and mackerel—known omega-3 powerhouses—are the way to go, she says. “Omega-3s are anti-inflammatory and support brain function, which may improve emotional well-being as part of a healthy dietary pattern,” Swanson says.

Additionally, omega-3s can “protect the integrity of eggs and sperm and enhance fertility,” according to the University of Pittsburgh Medical Center.

Swanson offers one important caveat: “No single food can do it alone!” she says. “What really matters is how your entire dietary pattern works together to shift the body’s systems in the right direction.”

A high-protein fall fertility recipe

“These Ultimate Meal-Prep Meatballs incorporate all the best flavors of fall,” Swanson says, and they combine many ingredients she listed above. This is a prime meal-prep dish that you’ll be able to nosh on for days to come.

• Preheat the oven to 400°F.
• Combine the following in a large mixing bowl:
  • 2 pounds organic ground turkey—Swanson adds that, for a fertility nutritional bonus, you can also include about 1 ounce of finely diced liver
  • 1 large sweet potato, cooked, peel removed, and mashed (about 1 cup total)
  • 1 to 2 pints of cranberries or blueberries
  • about 3.5 ounces crumbled feta
  • 2 heaping handfuls of dark leafy seasonal greens
  • 1 shallot (or equivalent red/purple onion), diced
  • Flavor enhancers: dried sage or a dash of cumin
• Roll mixture into bite-sized meatballs, then place about 30 each on two baking sheets.
• Bake for about 20 minutes, or until cooked through.
