Eggs vs Oatmeal – Which Is Better? Let’s Compare

Eggs and oatmeal are probably the two most popular breakfast options available. As a Certified Health Coach, many of my clients ask about which one is better. Can this question even be answered, which is better, eggs or oatmeal?

Eggs are better than oatmeal for weight loss, low-carb diets and sugar levels. According to the USDA, eggs contain 111% more protein, 7% fewer calories and 2,409% fewer carbohydrates when comparing 1 cup of cooked oatmeal to 2 large boiled eggs. Eggs have a lower glycemic index and provide more vitamins than oatmeal.

This article will include a side-by-side nutrient comparison between the two. I’ll examine which is better for certain goals like weight loss, bodybuilding and more. In addition, their glycemic index, satiety index and costs will all be covered.

In addition to coaching clients on both foods, I’ve purchased, researched and consumed both prior to, during and sometimes after writing this article. I personally consume both foods on a regular basis.

Eggs vs Oatmeal: Nutrient Comparison

Both foods have many of the same nutrients, but one has some the other doesn’t. The differences between the two can affect which one you choose or how you choose to eat them.

For this article I’m comparing one cup of cooked oatmeal without added ingredients to two hard boiled large eggs.

The following table is a side-by-side comparison of their nutrients.

Nutrient Resources 1 2

They both contain many of the same types of nutrients. This causes many people to ask, which is more healthier eggs or oatmeal?

Eggs are healthier than oatmeal due to fewer calories, carbohydrates and a higher percentage of protein and vitamins. Eggs provide more protein, vitamin A, vitamin D, B6, B5, folate, riboflavin and calcium.

Oatmeal is also healthy and provides a higher percentage of fiber, thiamin, niacin, magnesium, phosphorus, potassium, iron, copper and zinc than eggs.

I typically eat both eggs and oatmeal on different days to take advantage of each one’s nutrients.

Protein

2 large boiled eggs contain 111% more protein than 1 cup of cooked oatmeal.

Calories

2 large boiled eggs contain 7% fewer calories than 1 cup of cooked oatmeal.

Carbohydrates

2 large boiled eggs contain 2,409% fewer carbohydrates than 1 cup of cooked oatmeal.

The following video explains which is better for blood sugar.

Which to Choose

It seems you can’t go wrong choosing one over the other. Both foods are healthy and a great source of nutrients. Some people will alternate between the two foods to avoid boredom. Others have combined them in the same breakfast.

Some people have different goals. Picking one or the other may depend on your particular goals.

Weight Loss

One such goal is weight loss, which is better for weight loss?

Eggs are better for weight loss due to having fewer calories and carbohydrates than oatmeal. Two boiled eggs have 7% fewer calories than one cup of cooked oatmeal.

Eggs have a glycemic index of 0 compared to 55 for regular oatmeal. This means they take longer to digest and cause less spikes in blood sugar. This may make you feel fuller for longer.

In addition, some scientific studies have shown people feel fuller for longer after eating a breakfast consisting of eggs compared to oatmeal. Although oatmeal has a better satiety index score than eggs.

For more on glycemic index, satiety index and the studies mentioned, read more down further in this article.

Bodybuilding

If you’re in the gym lifting weights your goal may be to gain lean muscle mass. Which is better to build muscle?

Oatmeal is better for muscle gain than eggs due to its higher percentage carbohydrates and calories. The extra calories combined with the protein help to build and repair muscle. The extra carbohydrates help to provide energy while lifting weights.

I’ll always choose oatmeal over eggs on the mornings I go to the gym. I like the extra carbs which gives me more energy during my workouts.

Low-carb Diet

If your goal is to consume a low-carb diet then carbohydrates are your number one concern. Which has more carbohydrates?

Oatmeal has more carbohydrates containing 28.1 grams per one cup of cooked oatmeal. Two hard boiled eggs contain 1.12 grams of carbohydrates. If you’re on a Keto or low-carb diet, eggs is the better choice.

Gluten-Free

Oats are naturally gluten-free although some oats may come into contact with gluten products, or cross-contamination is possible with machinery or during storage. Always check the label of your food for the gluten free label.

Eggs are naturally gluten free although the way they are prepared at home or in restaurants put them at high risk for cross-contamination. The contamination may come from griddles, pans or utensils.

Recently it has been discussed many more people have at least a small amount of gluten intolerance and are unaware of it. Having less gluten in your diet is a good choice for most. 

Important: Although oats and granola made from just oats and honey are gluten free, they may come in contact with gluten-containing grains in storage or during transportation. Most of the Quaker oat products have solved this issue and label those products gluten free. Always check the label to determine if its gluten free.

Glycemic Index

The glycemic index of food is important especially if blood sugar levels are a concern. Avoiding blood sugar spikes is an important part of consuming healthy food. This is true for diabetics or anyone worrying about their health.

The Glycemic Index (GI) is a scale measuring how fast a particular food raises the blood sugar in the blood 3. Blood sugar spikes can lead to health complications with the heart, nerves, kidneys and eyes 4

Foods on the GI scale are categorized as:

  • Low-GI foods: 55 or under
  • Medium-GI foods: 56-69
  • High-GI foods: 70 or over

How blood sugars levels are affected:

  • Foods with a glycemic index 70 or more cause a quicker spike in blood sugar levels.
  • Foods with a glycemic index 56 to 69 cause a moderate spike in blood sugar levels.
  • Foods with a glycemic index 55 or less cause a slow spike in blood sugar levels.

Having more knowledge of the glycemic index of food and how it raises blood sugar, many people ask, which one has a higher glycemic index?

Eggs have a better glycemic index than oatmeal. Eggs fall into the low glycemic index with a GI of zero. Regular oats have a GI of 55. Steel-cut oats have a low GI under 55. Instant oatmeal has a higher glycemic index of 79.

Steel-cut has a lower GI because they are the least processed. Rolled oats are a little higher because they’ve been partially cooked. Quick oats have been steamed and rolled into thinner pieces to cook quicker. This process increases their glycemic index.

Satiety Index

Satiety is a term used to explain the feeling of being full and the loss of appetite which occurs after eating food. The satiety index is a scale showing how full a person feels after eating a certain food.

The satiety index was developed in 1995 from a study which tested 38 foods. The foods were ranked how they satisfied a person’s hunger. Foods scoring under 100 are considered less filling and foods scoring above 100 are considered more filling 5.

The table below shows the satiety scores of eggs, oatmeal and a few other breakfast foods.

Breakfast Food w/milk Satiety Index Score
Muesli 100%
Sustain 112%
Special K 116%
Cornflakes 118%
Eggs 150%
All-Bran 151%
Oatmeal w/milk 209%

Comparing the table above will help answer the question, does oatmeal keep you full longer than eggs?

Oatmeal will keep you full longer than eggs due to its higher satiety index of 209%. Eggs have a satiety score of 150%.

Of all the 38 total foods, oatmeal scored the fourth highest only beat by oranges, ling fish and boiled potatoes. Of the seven breakfast cereals with milk, oatmeal scored the best.

Of the 38 foods eggs scored the 14th best and the 3rd best of the breakfast foods.

High satiety food is likely to have a high satiety score for the following reasons:

  1. High in protein.
  2. High in fiber.
  3. High in volume (foods containing a lot of water or air).
  4. Low in energy density (foods low in calories for their weight).

Cooked oatmeal seems to fit into all four listed above.

  1. Oatmeal contains 7.9 grams of protein per 3/4 cup.
  2. Oatmeal provides 6.1 grams of fiber per 3/4 cup.
  3. Oatmeal weighs a good amount when prepared in relation to its calories.
  4. Oatmeal cooked is only 71 calories per 100 grams.

Does Oatmeal Really Have a Better Satiety Score?

I just finished saying it scored better than eggs in the 1995 study, so why am I asking this? I found another study in my research for this article saying otherwise.

Satiety Study

In a controlled study of 50 healthy individuals published in 2017 6, researchers studied the effects of egg vs. oatmeal breakfasts over 11 weeks. The study monitored both the cardiovascular disease biomarkers and the levels of ghrelin circulating in the blood.

Fasting plasma ghrelin is a hormone-releasing peptide secreted by the stomach when hungry. This promotes food consumption and weight maintenance. 

The results showed those who had two eggs a day at breakfast showed no evidence of cardiovascular disease markers over their oatmeal eating group. In addition, had greater satiety levels than the oatmeal group throughout the day.

Possible problem with the study.

The people were given flavored packets of oatmeal. Flavored packets are higher in sugar and probably should not have been used. Regular oatmeal doesn’t contain added sugars which may be why this study contradicts the 1995 study I mentioned above.

I think the research suggests both eggs and oatmeal is better at making you feel full than most other breakfast foods.

The following video has some egg recipes to help you prepare eggs different, healthy ways.

Health Benefits

Protein

Both foods are a good source of protein. Boiled eggs provide 110% more protein. Protein may help benefit the following:

  • Reduce appetite
  • Build and repair muscle
  • Boost metabolism
  • Weight loss

Potassium

Cooked oatmeal provides 30% more potassium.

Some medical experts recommend the potassium to sodium ratio of 4:1. Consuming too much sodium or not enough potassium throws off the delicate balance the kidneys need to remove the excess water 7.

Potassium helps the body get rid of excess sodium reducing fluid build-up. These help keep systolic and diastolic blood pressure lower 8.

According to Harvard Health, a number of studies have shown a connection between low potassium levels and high blood pressure 9. The more potassium, the more sodium your body will lose.

B Vitamins

Of the six B vitamins listed below, boiled eggs provide a higher percentage of four of them.

The B vitamins provided include the following:

  1. B1 (thiamin)
  2. B2 (riboflavin)
  3. B3 (niacin)
  4. B5
  5. B6
  6. B9 (folate)

B vitamins help support the following:

  • Brain function.
  • Red blood cells.
  • Digestion.
  • Nerve function.
  • Cardiovascular disease.
  • Energy levels.

A lack of B vitamins has been associated with oxidative stress and neural inflammation. In a study released in 2018 32 healthy adults were given B vitamin supplementation for six months. The results indicated preliminary evidence B vitamin supplementation reduced oxidative stress and inflammation 10.

Fiber

  • Cooked oatmeal contains 100% more fiber.

Foods high in soluble fiber are helpful for many reasons 11. What makes fiber soluble is it dissolves in water. 

Soluble fiber is known for the following:

  • Manage the blood glucose levels which helps decrease the risk of diabetes.
  • Helps avoid constipation and have a more regular stool.
  • Help overall digestive health.
  • Aids greatly in weight management because it allows you to feel full faster and eat less. 

Phosphorus

Cooked oatmeal provides 5% more phosphorus than boiled eggs.

Phosphorus has been shown in scientific studies to help with the following:

  • Promote bone and teeth strength.
  • Help the body store and manage energy.
  • Promote healthy nerve conduction.
  • Muscle contraction.
  • Muscle recovery.
  • Help the kidneys remove waste.

Magnesium

Cooked oatmeal provides 530% more magnesium than boiled eggs.

Magnesium helps keep blood pressure levels stable and balanced. Recent scientific research examined previous studies and concluded magnesium supplementation decreased systolic and diastolic blood pressure 12.

Magnesium helps control the following:

  • Muscle
  • Blood pressure
  • Blood sugar
  • Nerve function
  • Insomnia

In the heart and muscles, magnesium competes with calcium to help the muscles relax after contracting. When the body is low in magnesium, calcium can over stimulate the heart muscle’s cells causing a rapid or irregular heartbeat.

Calcium

Boiled eggs provide 150% more calcium.

Calcium is important for the heart and blood pressure. Harvard Health reports calcium helps maintain blood pressure by helping in the controlling of the relaxing and tightening of blood vessels 13.

Calcium also helps the following:

  • Help the muscles to function properly.
  • Helps nerve function.
  • Build and maintain strong bones.

Iron

Cooked oatmeal provides 77% more iron than boiled eggs.

Much higher in iron than other grains, oatmeal is an excellent choice if you need getting your daily value of iron. Iron is essential in the creation of red blood cells and is a necessary part of any healthy diet. 

Iron is also vital for growth and development, as some hormones need iron to be appropriately balanced 14.

The Prices

It seems every time I pay at the supermarket the price is higher than the last time. In addition, it seems I have less groceries in my shopping cart.

If you would like to spend less money at the supermarket, then the cost of food certainly matters. The price may sway your decision about which one to use in your meals more often. Therefore, which costs more?

Eggs costs more than oatmeal per serving. The average price for oatmeal is $0.18 per 40 gram serving. The average price for a 2 egg serving is $0.51. Eggs cost 180% more per serving than oatmeal.

To conduct some original research, I decided to search various different stores to compare the price of both. The eggs chosen were store brand and not organic, just regular white, large eggs.

I first visited the Shoprite supermarket for the prices of both:

  • Wholesome Pantry Organic old-fashioned regular
    • $2.49 per 18 oz container (13 servings) equaling $0.19 per 40 g serving
  • 12 Large Eggs (Bowl & Basket)
    • $3.49 per dozen (6 servings) equaling $0.58 per 2 egg serving

I then checked Walmart for the prices of both:

  • Quaker Old Fashioned Oats
    • $4.98 per 42 oz container (30 servings) equaling $0.17 per 40 g serving
  • 12 Large Eggs (Great Value)
    • $2.69 per dozen (6 servings) equaling $0.45 per 2 egg serving
