How much protein is in shrimp?

Shrimp is one of those rare foods that is almost pure protein. A 3 oz cooked serving (85g) carries about 20.4g of protein for roughly 84 calories, and the reason that ratio is so good is what isn’t in shrimp: under a gram of fat and essentially no carbohydrate per 100g. Strip those away and nearly every calorie that’s left is protein. By protein-per-calorie, shrimp sits alongside white fish, egg whites, and skinless chicken breast at the very top of the list — and like all of them, it’s a complete protein, supplying every essential amino acid your body can’t make on its own.

The cholesterol question, answered honestly

This is the thing everyone wants to know, so let’s be direct. Shrimp is high in dietary cholesterol — about 161mg in a 3 oz serving, more than most meats. For years that earned it a spot on the “avoid” list. But the science has moved on. What shrimp is not is high in saturated fat (it has about 0.1g per 100g), and saturated fat — not the cholesterol you eat — is the bigger driver of blood cholesterol for most people. Study after study has found that dietary cholesterol from foods like shrimp and eggs has little effect on blood cholesterol levels for the majority of healthy adults, which is why U.S. dietary guidance dropped its long-standing cap on cholesterol intake.

The practical takeaway: for most people, shrimp is a lean, smart source of protein, not a food to fear. The honest caveat is that a minority of people are “hyper-responders” whose blood cholesterol does react to dietary intake, and anyone managing heart disease should follow their doctor’s advice. But the blanket “shrimp will raise your cholesterol” warning hasn’t held up.

The gotcha: how it’s sold

The nutrition above is for plain cooked shrimp, and that’s the version worth eating. Where it gets muddy is the convenience packs. A lot of pre-cooked, peeled, “cocktail,” or frozen-then-thawed shrimp is treated with a salt or sodium-phosphate solution to retain moisture and improve texture. Plain shrimp runs about 111mg of sodium per 100g — low — but a treated product can carry several times that, turning a clean protein into a salty one. It’s the single biggest variable between two bags that look identical. Read the ingredient line: if you see salt, sodium tripolyphosphate, or sodium bisulfite, expect more sodium than the numbers here, and give it a rinse before serving.

Using it to hit a protein goal

Shrimp earns its keep when you’re chasing a number. About 20g of protein per 3 oz, for under 90 calories, means a standard dinner portion of 5–6 oz lands you 35–40g — a third or more of many people’s daily target — with almost nothing in the fat or carb columns to budget around. That makes it especially friendly to anyone counting macros, eating low-carb, or trying to keep calories down without skimping on protein. If you’re not sure what your daily number should be, our guide on how much protein per day walks through it. Shrimp won’t do all the work, but as a low-calorie, high-quality building block, few foods do more per bite.
