How much protein is in an avocado, per gram and per calorie

What people ask us next.

Q01

Does avocado have protein?

Yes, but very little relative to its calories. USDA lists raw avocado at 2.0 g of protein per 100 g in a food supplying 160 kcal, so a whole avocado of about 200 g of flesh provides roughly 4 g of protein and about 320 kcal. Expressed per 100 kcal that is 1.25 g of protein, against 18.8 g per 100 kcal for roasted chicken breast. Avocado is a fat and fiber food that happens to contain protein, not a protein source.

Q02

How much protein is in one whole avocado?

About 4 g. USDA lists 2.0 g of protein per 100 g of raw avocado, and a whole medium avocado yields roughly 200 g of edible flesh, giving about 4 g of protein alongside about 320 kcal, 29 g of fat, and 13 g of fiber. For comparison, a large egg supplies 6.3 g of protein for about 72 kcal, so one egg carries more protein than an entire avocado at roughly a fifth of the calories.

Q03

Is avocado a good source of protein?

No, and the per-calorie math shows why. Avocado delivers 1.25 g of protein per 100 kcal, against 18.8 g per 100 kcal for roasted chicken breast and 8.8 g per 100 kcal for a large egg. Reaching a single 30 g protein serving from avocado alone would take about 1.5 kg of flesh and roughly 2,400 kcal. It is a good source of monounsaturated fat, fiber, and potassium, which are the reasons to eat it.

Q04

Is avocado protein a complete protein?

Technically yes, and it matters less than it sounds. Avocado protein contains all nine indispensable amino acids, so it meets the definition of complete. But completeness describes the amino acid pattern of the protein present rather than how much protein is there, and 2 g per 100 g is too little to affect a daily target. Protein quality metrics only become useful once the quantity is large enough to contribute meaningfully.

Q05

What is avocado actually high in?

Fiber, monounsaturated fat, and potassium. USDA lists 6.7 g of fiber per 100 g, which is higher than most fruit, 14.7 g of total fat per 100 g that is predominantly monounsaturated, and 485 mg of potassium per 100 g, which is substantial for a plant food. Those three explain both the satiety effect and its value in diets where potassium intake runs low relative to sodium. The 160 kcal per 100 g is the trade-off to account for.

Q06

Should I count avocado toward my daily protein target?

Not meaningfully. At about 4 g per whole fruit it moves a daily protein figure by a rounding error while adding around 320 kcal, which is the number worth tracking. The better approach is to log avocado in the fat column, count its calories honestly, and source the protein from whatever it is served with. In an avocado toast breakfast, for instance, the protein is coming from the eggs, dairy, or bread, not the avocado.
