Eggs are a breakfast staple in many American homes—and for good reason. They’re rich in protein, vitamins, and healthy fats that support energy, muscle health, and brain function. But according to health educator Barbara O’Neill, some common food pairings may reduce the nutritional benefits of eggs or make them harder to digest.
While this may sound surprising, the idea is simple: not all nutrients work well together. Just like certain medications can interact, certain foods can too—and that includes everyday combinations like eggs with toast or fruit. Let’s explore what the research says and how to make the most of your egg-based meals.
Why Eggs Are a Nutritional Powerhouse
Before diving into what not to pair with eggs, it’s helpful to understand why they’re so beneficial:
- High-quality protein: Eggs contain all nine essential amino acids.
- Brain-boosting nutrients: Including choline, which supports memory and cognitive health.
- Eye health support: Thanks to antioxidants like lutein and zeaxanthin.
- Heart-healthy fats: Especially in pasture-raised or omega-3-enriched eggs.
- Affordable and versatile: Easy to prepare in a variety of ways.
However, the benefits of eggs can be diminished if they’re paired with foods that interfere with absorption or slow down digestion.
The Idea Behind Nutrient Cancellation
Barbara O’Neill and other natural health educators often discuss “nutrient blocking”—when certain foods make it harder for your body to absorb key vitamins or minerals. While not a widely used medical term, the concept is supported in nutrition science.
Some food combinations:
- May bind to nutrients and carry them out of the body before absorption.
- Can slow digestion, reducing how efficiently the body uses nutrients.
- Might spike blood sugar and lead to energy crashes when paired poorly.
So, what foods might work against your eggs instead of with them?
1. Avoid Pairing Eggs With High-Oxalate Vegetables
While veggies are generally a healthy addition to any meal, some high-oxalate greens—like spinach, beets, or Swiss chard—can interfere with calcium absorption from eggs.
- Why? Oxalates bind to calcium, forming crystals the body can’t absorb.
- Eggs contain calcium and fat-soluble vitamins that rely on proper absorption.
Try this instead:
- Pair eggs with lower-oxalate greens like kale, arugula, or broccoli.
- Steam your greens to reduce oxalate levels.
2. Don’t Combine Eggs and Processed Meats Regularly
Eggs and bacon may be the classic American combo, but processed meats like bacon or sausage can raise sodium and saturated fat intake significantly.
- Harvard Health warns that frequent consumption of processed meat is linked to heart disease risk.
- The combination may leave you feeling sluggish and counteract eggs’ healthy benefits.
Better choice:
- Try avocado slices, grilled tomatoes, or roasted sweet potatoes for a satisfying, heart-smart pairing.
3. Be Careful With Fruit Juices
Many people wash down their eggs with orange juice or another fruit drink. However, fruit juice is high in sugar and low in fiber, which can cause a rapid blood sugar spike.
- When paired with protein and fat from eggs, this can lead to poor energy balance or midmorning crashes.
- Some acids in juice may also interfere with the absorption of iron or zinc, both found in egg yolks.
Try this instead:
- Enjoy whole fruit like berries or apple slices 30–60 minutes before or after your eggs.
- Drink water, herbal tea, or even warm lemon water with breakfast.
4. Skip Combining Eggs With White Bread or Refined Carbs
Eggs on toast may seem harmless, but refined white bread adds little nutrition and may actually dampen the benefits of your meal.
- Refined carbs are digested quickly, leading to blood sugar spikes that compete with the steady energy from protein.
- They also offer minimal fiber, which helps keep you full.
Better options:
- Swap white bread for whole-grain, sprouted grain, or sweet potato toast.
- Add healthy fats like olive oil or nut butter to stabilize blood sugar.
5. Watch Out for Too Much Cheese
Egg and cheese omelets are tasty and filling—but excess cheese can add high levels of saturated fat and sodium, especially if it’s processed.
- Overdoing cheese can weigh down digestion and add more calories than you realize.
- It may also compete with iron absorption in some meals.
Try this instead:
- Use a small amount of sharp, high-flavor cheese like goat cheese or feta.
- Or, skip cheese and flavor with fresh herbs, avocado, or a touch of salsa.
Tips to Get the Most Nutrition From Your Eggs
Here are a few evidence-based ways to enjoy eggs and boost their nutritional value:
- Use gentle cooking methods: Poaching or soft-boiling preserves more nutrients.
- Include healthy fats: A little avocado or olive oil helps your body absorb fat-soluble vitamins (A, D, E, K).
- Pair with fiber: Think lightly sautéed veggies, whole grains, or beans.
- Eat them earlier in the day: Eggs provide steady energy, making them ideal for breakfast or brunch.
- Don’t fear the yolk: It’s packed with vitamins and healthy fats (unless your doctor advises otherwise).
What About Barbara O’Neill’s View?
Barbara O’Neill emphasizes digestive simplicity—not overwhelming the stomach with too many conflicting foods at once. Her approach supports:
- Eating fruit alone, on an empty stomach
- Keeping meals simple and easy to digest
- Avoiding hard-to-combine ingredients like animal protein with starchy carbs
While not every expert agrees on all points, the takeaway is consistent: how you combine your food matters—and your body will usually tell you what works best.
Final Thoughts: Listen to Your Body and Keep It Simple
Eggs are one of the most nutrient-dense foods available. But what you eat with them can influence how well your body uses those nutrients.
If you often feel sluggish, bloated, or tired after breakfast, consider rethinking your food pairings. Avoid mixing eggs with high-sugar, high-sodium, or hard-to-digest foods, and aim for simple, balanced meals.
