You can find protein in plenty of everyday meals in Vietnam: chicken with rice, grilled fish, eggs, tofu, or a pot of yogurt. The useful question is how much of that food is in your serving.
A plate of cơm gà with a small piece of chicken and one with an extra portion of meat will give you different amounts of protein. This guide helps you order, shop, and compare portions without needing to turn every lunch into a calculation.
What to buy or ask for locally
| Food or meal | Useful Vietnamese words | What to check |
|---|
| Chicken with rice | cơm gà; thêm thịt for extra meat | Edible chicken quantity, skin, bones, and sauce vary |
| Fish with rice | cơm cá | Fish species, edible portion, and cooking method |
| Tofu | đậu phụ or đậu hũ | Plain, fried, and packaged tofu can have different values |
| Boiled eggs | trứng luộc | Egg size and edible weight |
| Plain yogurt | sữa chua không đường | Unsweetened yogurt is not automatically Greek yogurt or high in protein |
You can ask for thêm trứng (an extra egg) or thêm thịt (extra meat), then check availability and price with the vendor. If you have food allergies or dietary requirements, confirm ingredients and sauces directly rather than relying on the dish name.
For supermarket shopping, read the actual package. Greek yogurt, milk, tofu, and canned fish vary between brands. Keep perishables appropriately chilled. A packaged bar is another ready-portioned option; the buying guide explains website delivery and physical stockists.
How to estimate protein when you are eating out
Start with its protein source, identify its cooked or raw state, and estimate the edible portion. Rice, noodles, oil, sauces, and other ingredients contribute separately. One universal number for a bowl of phở or a plate of cơm gà would hide these differences.
At home, a kitchen scale and the food's label make the job easier. When eating out, ask about the portion and use a reasonable estimate. The name of a dish will only get you so far.
Protein and calories by portion
The table uses USDA FoodData Central reference foods, with a source for each row. Compare the portions, then check your own package when you have a label: brands and cooking methods can change the values.
| Food and state | Protein / 100 g | Example portion | Protein / portion | Kcal / portion |
|---|
| Cooked chicken breast, meat only, no skin | 31.0 g | 100 g | 31.0 g | 165 |
| Tilapia, cooked with dry heat | 26.2 g | 120 g | 31.4 g | 154 |
| Light tuna canned in water, without added salt, drained | 25.5 g | 80 g | 20.4 g | 93 |
| Hard-boiled egg, shelled | 12.6 g | 100 g, about 2 large eggs | 12.6 g | 155 |
| Firm tofu prepared with calcium sulfate, before cooking | 17.3 g | 150 g | 26.0 g | 216 |
| Regular tofu prepared with calcium sulfate, before cooking | 8.1 g | 150 g | 12.1 g | 114 |
| Prepared edamame, shelled beans | 11.9 g | 100 g | 11.9 g | 121 |
| Plain low-fat Greek yogurt | 10.0 g | 170 g | 16.9 g | 124 |
| 2% milk | 3.3 g | 200 g | 6.6 g | 100 |
Protein is rounded to 0.1 g and energy to the nearest kcal. Calculations use the original values before rounding, so multiplying a rounded per-100 g figure can produce a small difference. Oil, sauces, and side dishes are excluded. Milk is weighed in grams; 200 g is not assumed to be exactly 200 ml.
Why the two tofu entries differ
The USDA records for regular and firm tofu list 8.08 g and 17.3 g protein per 100 g respectively. They describe different foods, rather than two calculations for the same piece of tofu.
Tofu's water content and how it is made affect its protein concentration. A market stall's “firm tofu” may not match the firm-tofu record above. Use the package's nutrition panel when available, and treat the table as a rough guide when there is no label.
Should you weigh food raw or cooked?
Match the database record to the food on the scale. The chicken entry above describes cooked meat. You cannot weigh 100 g of raw chicken and assign it the cooked entry's 31 g protein directly.
Useful notes include “100 g cooked chicken breast, no skin” or “150 g tofu before steaming.” They make comparisons more consistent and keep bones, shells, or canning liquid out of the edible portion.
For a batch-cooked dish, you can calculate from the starting ingredients using matching records, then divide the total between portions. Include cooking oil and sauces separately rather than assuming they are already counted in the meat or tofu values.
Comparing protein with calories
In these records, 100 g cooked chicken breast provides about 31 g protein and 165 kcal. The regular tofu entry provides about 8.1 g protein and 76 kcal per 100 g. Comparing calories alone overlooks the different amount of protein.
At approximately 20 g protein, calculations from those same records give:
| Calculation example | Approximate food quantity | Approximate energy |
|---|
| Cooked chicken breast providing 20 g protein | 65 g | 106 kcal |
| Regular tofu providing 20 g protein | 248 g | 188 kcal |
Here, 20 g is simply a comparison point. Tofu may still be the option you prefer for its taste, price, or place in a plant-based meal. The quantities are calculated before rounding, so a hand calculation from the rounded table may differ slightly.
Use the table with familiar meals
Start with the meal you want to eat, then identify its protein sources:
- Rice with meat or fish: estimate the edible meat or fish portion, then add rice, vegetables, and other dishes to suit your needs.
- A tofu rice meal: identify the tofu you use. Recalculate if you switch to fried tofu or a package with different nutrition information.
- Eggs or yogurt at breakfast: use the actual weight or package serving rather than an assumed standard egg or pot.
- An office snack: our high-protein snack guide offers ideas that fit a workday.
You can spread your protein choices across the day: eggs at breakfast, fish or tofu at lunch, and another food you enjoy at dinner. Start with meals you already like, then adjust the portions if you need to.
Where a protein bar fits
A packaged bar offers a defined serving and a label you can check. Yobeve's figures per one 50 g bar are:
These are product-label figures, shown separately from the USDA food records. Both bars contain milk protein and collagen. They are not vegan, and a bar alone is not a complete meal replacement.
A bar offers convenience when you want a ready-portioned snack. Eggs, fish, tofu, and other foods provide different meal options when you have time to prepare them. Read what a protein bar is for a closer look at the format.
Common questions
Does 100 g of food mean 100 g of protein?
No. Food weight includes water, protein, fat, and other components. In the record above, 100 g of hard-boiled egg provides around 12.6 g protein. Our protein basics guide explains the nutrient itself.
How much protein is in one egg?
Using the record above, 50 g of shelled hard-boiled egg provides about 6.3 g protein. Eggs vary in size, so weighing gives a closer estimate than assigning every egg the same number.
How much protein should I eat each day?
That depends on factors including your body weight and activity. Our protein guide for gym training explains the exercise context. Once you have a daily reference in mind, use the table to see how your usual foods contribute.
