How Nutrition and Diet Affect Fertility

When you’re trying to conceive, it’s normal to start thinking more about what’s on your plate. You might hear a lot of different advice about “fertility diets,” supplements or foods you should avoid.

The truth? There’s no single perfect way to eat for fertility.

But there are some simple nutrition principles that can help promote hormone balance, egg and sperm health, and overall wellness. The goal is to build nourishing habits that support your body along the way.

Let’s break it down.

The Building Blocks of Fertility Nutrition

Your body relies on three main nutrients, called macronutrients, to function properly: protein, fats and carbohydrates. Here’s how each one plays an important role in reproductive health.

Protein

Protein helps build and repair tissues and supports hormone production. It’s also important for egg quality and overall reproductive function. Good sources include eggs, fish, poultry, beans, lentils, nuts and seeds.

Healthy fats

Fats have a bad reputation, but healthy fats are essential for hormone production, especially reproductive hormones like estrogen and progesterone. Foods like avocados, olive oil, nuts, seeds and fatty fish (like salmon) are great sources.

Complex carbohydrates

Carbohydrates provide energy and help regulate blood sugar levels, which can influence hormone balance and ovulation. Choose fiber-rich carbs like whole grains, sweet potatoes, legumes, fruits and vegetables.

When possible, aim for meals that include a balance of all three: protein, healthy fat and fiber-rich carbohydrates.

Small Nutrients That Make a Big Difference

In addition to macronutrients, your body needs micronutrients — vitamins and minerals that support everything from immune health to hormone production.

Some nutrients are especially important when preparing for pregnancy.

• Folate (vitamin B9) helps support early fetal development. You’ll find it in leafy greens, lentils, citrus fruits and avocado.
• Vitamin B12 supports nerve function and red blood cell production. It’s found in foods like fish, eggs, dairy and poultry.
• Iron helps transport oxygen throughout the body and supports ovulation. Good sources include red meat, beans, spinach and lentils.
• Omega-3 fatty acids may help reduce inflammation and support egg quality. These are found in fatty fish, walnuts, chia seeds and flaxseeds.
• Vitamin D supports hormone balance and immune health. Sunlight, fortified dairy, egg yolks and fatty fish can help boost levels.
• Zinc supports hormone production and sperm health. Pumpkin seeds, nuts, beans and lean meats are good sources.
• Choline plays a key role in oocyte development, embryo growth, placental function and early fetal brain development. Sources include eggs, seafood, meat and poultry.

Because nutrient stores build over time, focusing on nutrition in the months before pregnancy can help create a supportive environment for conception.

Simple Strategies for Eating Smart

When it comes to eating for fertility, four simple ideas can help guide your choices.

1. Balance

Try to include a mix of protein, healthy fats and carbohydrates at meals. This helps support steady energy and hormone balance.

2. Nutrient density

Focus on foods that provide lots of nutrition (like vegetables, fruits, eggs, fish, beans and whole grains), rather than foods that provide mostly empty calories (like sugary drinks, sweets and desserts, fast food, white bread and white pasta, sugary cereal and alcohol).

3. Nutrient quality

Whole, minimally processed foods tend to provide nutrients that your body can easily absorb.

4. Nutrient frequency

Eating regularly throughout the day can help maintain steady blood sugar and energy levels.

For example, a balanced day of eating might include eggs and whole-grain toast for breakfast, yogurt and berries as a snack, a protein-rich salad for lunch, nuts and fruit in the afternoon, and fish with vegetables and whole grains for dinner.

Example Daily Nutritional Menu

Eat the Rainbow

One easy way to boost nutrition is to eat a variety of colorful fruits and vegetables.

Different colors provide different vitamins, antioxidants and plant nutrients that support overall health.

Think strawberries and tomatoes (red), carrots and sweet potatoes (orange), bananas (yellow), spinach and broccoli (green), and eggplant or purple cabbage (purple). The more variety, the better!

What About Organic Foods?

Organic foods aren’t required for a healthy fertility diet, but some people choose them to reduce exposure to pesticides.

If buying organic isn’t always practical or within your budget, that’s OK. Washing produce thoroughly and focusing on variety can still support good nutrition. Frozen fruits and vegetables can also be a nutritious and budget-friendly option.

Another Option? The Mediterranean Diet

The Mediterranean Diet is a heart-healthy, anti-inflammatory eating plan that supports weight loss, hormone balance and improved fertility. It emphasizes whole, nutrient-dense foods that promote ovulation, egg quality and reproductive health while reducing inflammation and stabilizing blood sugar levels.

Here is a simple three-day Mediterranean diet meal plan:

Don’t Forget Hydration

Water plays an important role in circulation, metabolism and overall health.

Hydration needs vary, but general guidelines suggest about 9 cups of fluids daily for people with ovaries and about 12 cups for people with sperm. Water, herbal tea and other non-sugary drinks all count.

Progress Over Perfection

Nutrition is just one part of your fertility journey. And food is more than fuel; it’s also social, cultural and enjoyable.

Instead of aiming for a perfect diet, many people find success with an 80/20 approach: Focus on nourishing foods most of the time, while still allowing space for flexibility and foods you love.

Small, consistent changes can add up over time. And when it comes to supporting fertility, those habits can make a difference.
