Rockstar athletes do it. Your grandma might have done it in her morning "egg cream" or malt. If you’ve ever licked a spatula covered in cookie dough, you’ve done it too. But the question of should you eat raw eggs is one of those health debates that never seems to die, mostly because the answer isn't a simple yes or no. It’s a calculated risk.
People freak out about Salmonella. Honestly, for good reason. It’s a nasty bacteria that can turn your bathroom into a temporary residence for forty-eight hours of pure misery. Yet, the fitness community—specifically the old-school bodybuilding crowd—clings to the raw egg habit like it’s a sacred ritual for muscle growth. They point to the enzymes. They talk about "bioavailability."

They might be wrong about that last part.
Let’s look at the science. When you cook an egg, you change the protein structure. This process is called denaturation. A landmark study published in the Journal of Nutrition found that the human body absorbs about 90% of the protein in cooked eggs, but only about 50% in raw eggs. Think about that. You're basically flushing half your gains down the toilet because your body can't break down those tightly bound raw proteins as efficiently. It’s a weird paradox. We’ve been told raw is more "natural," but for our digestive tracts, heat is actually a huge help.
The Salmonella Risk vs. The Reality
Most people think the bacteria is only on the shell. If you’re careful not to let the outside touch the inside, you’re safe, right? Not exactly. Salmonella enteritidis can actually be inside the egg before the shell even forms if the hen itself is infected.
The USDA and the CDC are pretty firm on this: don't do it. They recommend cooking eggs until the yolks are firm. But we live in a world of Caesar dressing, hollandaise sauce, and tiramisu. We’re clearly ignoring the feds.
Statistically, the risk is lower than it used to be. Estimates suggest about 1 in every 20,000 eggs is contaminated. If you eat one raw egg every day, you might hit the "poison jackpot" once every 54 years. Does that make it safe? For a healthy 25-year-old, it’s a gamble with decent odds. For a pregnant woman, a young child, or someone with a compromised immune system, that gamble is potentially life-threatening. The risk isn't just a stomach ache; it's sepsis or severe dehydration.

Biotin: The Beauty Vitamin Trap
There’s a weird thing in eggs called avidin. It’s a protein in the egg white. In its raw state, avidin loves biotin—a B-vitamin essential for your hair, skin, and metabolism. It loves it so much that it binds to it and prevents your body from absorbing it.
If you eat raw egg whites occasionally, it’s no big deal. But if you make it a daily habit? You could actually develop a biotin deficiency. This leads to thinning hair, skin rashes, and even neurological issues. Cooking the egg completely neutralizes the avidin. It’s one of those rare cases where processing (via heat) makes the food significantly more nutritious by removing an "anti-nutrient."
Why People Still Do It
So, why are we still asking should you eat raw eggs if the protein absorption is lower and there's a risk of bacteria?
- Convenience. It takes ten seconds to crack three eggs into a blender with some oats and milk. It takes ten minutes to scramble them. In a world of "hustle culture," those nine minutes and fifty seconds feel like an eternity.
- Heat-sensitive nutrients. While cooking helps protein absorption, it does slightly degrade some antioxidants like lutein and zeaxanthin, which are great for your eyes. It also lowers the levels of Vitamin A and certain B-vitamins.
- The "Alpha" Factor. There is a psychological component to raw consumption. It feels "hardcore." It’s the Rocky Balboa effect.
If you are going to do it, you have to be smart. Don't buy the cheap, mass-produced eggs from a massive factory farm where chickens are crammed together. Those are the breeding grounds for disease. If you’re set on raw consumption, look for "pasteurized" eggs.
Pasteurization involves heating the eggs in their shells to a temperature just high enough to kill the bacteria but not high enough to actually cook the egg. It's a game changer. Most grocery stores carry them, though they cost a bit more. It’s basically insurance for your intestines.
The Japanese Context
We can't talk about this without mentioning Japan. In Japan, raw eggs are a staple. Tamago kake gohan (raw egg over hot rice) is a national comfort food. Why aren't people dropping like flies there?
It comes down to the supply chain. Japan has incredibly rigorous cleaning and testing standards for their egg production. They often vaccinate the hens against Salmonella. In the U.S., the focus is more on washing the eggs after they are laid, which actually strips away a natural protective coating called the "cuticle," making the egg more porous. This is why Americans have to refrigerate eggs while Europeans don't.
Breaking Down the Nutrition Facts
- Cooked Egg Protein Bioavailability: ~91%
- Raw Egg Protein Bioavailability: ~51%
- Calories: Identical (approx. 70-80 per large egg)
- Fats: Mostly stable, though heat can oxidize some cholesterol (not a major concern for most)
Wait, let's talk about the cholesterol. For years, eggs were the villain. Now we know dietary cholesterol doesn't impact blood cholesterol for about 75% of the population. Whether it's raw or cooked, the egg yolk is a nutrient powerhouse. It's got choline, which is basically brain fuel. It has healthy fats. It's one of the few natural food sources of Vitamin D.
Actionable Steps for the Egg-Curious
If you're still weighing the pros and cons, here is how you should actually handle this in your daily life.
First, identify your risk category. If you’re an athlete with a stomach of steel, your risk profile is different from someone who is 70 years old. If you fall into a vulnerable group, just don't do it. It’s never worth the risk of a hospital stay for a "natural" protein shake.
Second, check the carton. If you're using eggs for a raw mousse or a homemade mayo, buy pasteurized eggs. If the carton doesn't say "pasteurized," assume it's not.
Third, hygiene matters. Wash your hands after handling the shells. Don't let the raw egg sit out at room temperature for hours. Bacteria loves heat, but it also loves a lukewarm kitchen counter.
Fourth, consider the "sunny side up" compromise. If you want the runny yolk for the nutrients and the flavor, but want to avoid the avidin/biotin issue, cook the white until it's opaque and leave the yolk liquid. This is the sweet spot. You get the best protein absorption from the cooked white and keep the delicate nutrients in the yolk intact.

Ultimately, the "benefits" of eating raw eggs are mostly a myth. You aren't getting more protein—you're getting less. You aren't getting a magical enzyme boost that justifies the risk of Salmonella. The only real benefit is speed and a specific texture in certain recipes.
If you’re doing it to be a "beast" in the gym, you’re better off boiling them. If you’re doing it because you love a good steak tartare or a traditional whiskey sour with egg white foam, just buy the pasteurized ones and enjoy your meal without the looming fear of a fever.
Stop treating raw eggs like a health hack. They’re an ingredient, not a miracle.
Final Checklist for Safe Handling:
- Buy eggs that have been refrigerated since the farm.
- Discard any eggs with even tiny cracks in the shell.
- Store eggs in the main body of the fridge, not the door (the door temperature fluctuates too much).
- Eat dishes containing raw eggs immediately after preparation.
- When in doubt, use heat. 160°F is the magic number to kill off the bad guys.
