Couscous and rice are both popular grains that are enjoyed around the world. Many people wonder if one is a healthier choice than the other when it comes to carbohydrate content. This article will examine the nutritional profiles of couscous and rice, comparing their carb contents as well as other macronutrients. We’ll also look at the glycemic index of each grain and factors that affect carb content, like cooking methods and serving sizes. Read on to find out whether couscous or rice is the better low-carb option!
Carb Content of Couscous vs Rice
Couscous and rice do have some key differences when it comes to their carb content. Here is an overview of the carb levels in each:
Couscous
– 1 cup of cooked couscous contains about 36-43 grams of total carbs.
– Of these carbs, 2-3 grams come from fiber while the rest are starch and sugars.
– So the net carb count per 1 cup of couscous is around 33-40 grams.
Rice
– 1 cup of cooked white rice contains around 45 grams of total carbs.
– This includes about 0.6 grams of fiber, so the net carbs are around 44 grams.
– Brown rice has a bit more fiber, so 1 cup contains around 36 grams of net carbs.
Based on these nutrition facts, we can see that couscous is slightly lower in net carbs than white or brown rice per cup when cooked. Couscous has about 7-11 fewer net carbs than a comparable serving of rice.
However, the differences are relatively small. Both grains are high-carb options and contain over 30 grams of net carbs per serving.
Other Macronutrients in Couscous and Rice
In addition to carbs, we should also look at how couscous and rice compare in protein and fat content:
Protein
– Couscous contains around 6 grams of protein per cooked cup.
– Rice contains about 4-5 grams of protein per cooked cup.
Fat
– Couscous contains 0.5-1 gram of fat per cooked cup.
– Rice contains almost no fat, with 0.5 grams or less per cup.
So couscous does have a bit more protein and fat compared to white or brown rice. But both grains are relatively low in these macronutrients and get the bulk of their calories from carbs.
Glycemic Index
The glycemic index (GI) is a measure of how quickly a food raises blood sugar levels. Foods with a high GI cause faster, more dramatic spikes while low-GI foods have a gentler effect.
Here are the GI values for each grain:
– Couscous has a moderate GI of around 65.
– White rice has a very high GI of 73.
– Brown rice has a medium GI of 66.
Based on the GI, couscous has a slightly more favorable effect on blood sugar compared to both varieties of rice. But neither grain is particularly low-GI.
Factors Affecting Carb Content
Beyond the inherent nutritional profiles of couscous and rice, several other factors can alter their carb contents:
Cooking Method
– Rinsing rice before cooking can reduce its starch and carb content slightly.
– Cooking rice pasta-style in excess water that’s drained away also removes extra starch.
– Couscous is made by steaming granules of durum wheat semolina, so no changes in cooking method would alter its carb content.
Portion Size
– Carb content scales up or down based on the serving size of either couscous or rice.
– 1/2 cup of cooked couscous would have around 16-20 net carbs.
– 1/2 cup of rice would have 22-27 net carbs.
Additions and Toppings
– Adding items like vegetables, proteins, oils, or sauces creates a mixed dish with diluted carb levels.
– Plain couscous or rice keeps the starch content concentrated.
So smaller portions, cooking methods, and additions can potentially reduce the net carbs – but the core carb content remains similar.
Couscous and Rice Carb Density
If we look at the density of carbs in couscous versus rice, this also provides some insight:
Couscous
– Dry couscous contains about 77 grams of total carbs per 100 grams.
– So it provides 77 carb grams in a 100-gram dry serving.
Rice
– Dry white rice contains about 80 grams of total carbs per 100 grams.
– Brown rice contains around 77 carb grams per 100 grams dry.
– So white or brown rice offer about 80 and 77 carb grams respectively in a 100-gram dry serving.
The dry carb density shows couscous and rice are very close, though couscous edges out rice slightly. This matches the info on cooked carb content.
Fiber Content
Fiber is a type of carbohydrate that our bodies cannot digest. So high fiber foods essentially have fewer net carbs:
– Couscous is low in fiber, with only 2-3 grams per cooked cup.
– Rice is also low in fiber. White rice has under 1 gram per serving while brown rice has around 2 grams.
Neither grain provides significant amounts of fiber to reduce net carbs. Couscous is barely higher than white or brown rice.
Impact on Blood Sugar
Due to their similar carb density, glycemic index, and low fiber, couscous and rice have a comparable impact on blood sugar:
– They both raise blood sugar significantly thanks to their high net carb content per serving.
– The GI indicates couscous causes a slightly slower blood sugar rise compared to white or brown rice.
– But neither has a strong advantage for regulating blood sugar due to the high baseline carb levels.
For managing blood sugar, portion size control is important with both couscous and rice. Sticking to 1/2 cup servings or less can prevent spikes.
Couscous and Rice in Low-Carb Diets
Low-carb diets like the ketogenic diet often aim for a threshold of around 50 grams of net carbs per day. For reference:
– The standard serving of 1 cup of couscous contains up to 40 grams net carbs.
– A serving of rice contains over 35 grams of net carbs.
So a single serving of either grain would provide nearly a whole day’s allotment of carbs on a strict low-carb diet.
Smaller 1/4 or 1/2 cup portions could potentially be incorporated, but both couscous and rice are high-carb options ill-suited for very low carb eating plans.
Low-Carb Alternatives
For a low-carb grain alternative, cauliflower rice is a popular option with only 5 grams of net carbs per cup.
Some other low-carb grain alternatives include:
– Quinoa: 20 net grams per cup
– Bulgur wheat: 26 net grams per cup
– Barley: 21 net grams per cup
– Spelt berries: 20 net grams per cup
– Kamut: 25 net grams per cup
While these contain more carbs than cauliflower rice, they provide around half the net carb content of traditional rice or couscous per serving.
Couscous and Rice Glycemic Load
Glycemic load considers both a food’s GI and the carb content per serving. It better represents effects on blood sugar in normal portions. The glycemic load for each grain is:
Couscous
– GI of 65
– 40 grams net carbs per serving
– Glycemic load of 26 (65 x 0.4 per serving)
White Rice
– GI of 73
– 44 grams net carbs per serving
– Glycemic load of 32 (73 x 0.44 per serving)
Brown Rice
– GI of 66
– 36 grams net carbs per serving
– Glycemic load of 24 (66 x 0.36 per serving)
Couscous and brown rice have a similar glycemic load around 25 per serving. White rice is higher at 32 due to the elevated GI.
Overall, this indicates couscous and brown rice provide a comparable effect on blood sugar over time.
Nutritional Profile Comparison
| Nutrient (per 1 cup cooked) | Couscous | White Rice | Brown Rice |
|---|---|---|---|
| Calories | 176 | 205 | 216 |
| Net carbs | 33g | 44g | 36g |
| Fiber | 2g | 0.6g | 2g |
| Protein | 6g | 4g | 5g |
| Fat | 0.5g | 0.5g | 1.5g |
This table summarizes and compares the full nutritional profiles side-by-side. The key takeaway is couscous and rice have near-identical carb and fiber contents, with couscous slightly lower in net carbs.

Cost Comparison
On average, couscous costs slightly more per pound compared to most varieties of rice in the US:
– Couscous ranges from $3 to $5 per pound at most grocery stores.
– White rice averages about $2 per pound.
– Brown rice costs around $2 to $3 per pound.
The small price difference reflects the fact that couscous is higher in demand worldwide. But rice remains the cheaper bulk grain option overall in the US market.
Worldwide Consumption
Rice is one of the most widely consumed grains globally. Couscous is also popular, but primarily eaten regionally:
– Rice is a staple food for nearly half the world’s population in Asia, Latin America, and Africa.
– Couscous consumption is concentrated mostly in North Africa, parts of the Middle East, and the Caribbean.
– The average worldwide consumption of rice is over 50 pounds per person annually.
– Average couscous consumption is around 25 pounds per person in countries where it is common.
So while both grains are eaten internationally, rice plays a larger dietary role across more cultures globally. Couscous remains largely a regional favorite.
Conclusion
In the end, couscous does have slightly fewer net carbs compared to white or brown rice per serving when cooked. But the difference amounts to just 7-11 grams less per cup.
Both couscous and rice are high-glycemic, high-carb options unsuitable for strict low-carb diets. Their carb contents are comparable, with rice providing more affordable and globally-consumed source of bulk calories.
From a health perspective, couscous is not clearly “lower carb” than rice. Portion control and overall eating pattern matter more than choosing one over the other. Both can be enjoyed in moderation as part of a balanced diet that limits refined starch intake from all sources.
