Once considered purely a North African delicacy, couscous is a processed grain that offers nutritional benefits in form of selenium and plant-based protein. However, this grain contains gluten, making it not suitable for everyone. So, should we consume couscous?Nutritional Benefits of CouscousRich in SeleniumOne of the standout nutrients in couscous is selenium. A single cup (157 grams) offers over 60% of the recommended daily intake. Selenium is a crucial mineral with several health benefits—it acts as a powerful antioxidant, supports cellular repair, and reduces inflammation. It also plays a key role in maintaining thyroid health by aiding hormone production and protecting the thyroid gland from damage. Additionally, selenium may help reduce the risk of heart disease by lowering oxidative stress and preventing plaque buildup in arteries.May Help Lower Cancer RiskThe selenium content in couscous could also contribute to a reduced risk of certain cancers. Findings from a review involving more than 350,000 participants indicate that higher selenium levels in the blood—primarily from dietary sources—may offer protection against specific cancers. Notably, selenium deficiency has been associated with an increased risk of prostate cancer, and a combination of adequate selenium, vitamin C, and vitamin E may lower lung cancer risk among smokers.Boosts the Immune SystemCouscous may give your immune system a boost, thanks again to its selenium content. Selenium enhances immunity by reducing oxidative stress and supporting immune cell function. It also assists in regenerating vitamins C and E, which play a role in strengthening immune responses.Good Source of Plant-Based ProteinProtein makes up around 16–20% of the human body and is essential for metabolic processes. Couscous provides about 6 grams of plant-based protein per one-cup serving. While it is not a complete protein—meaning it doesn't contain all essential amino acids in adequate amounts—it can be paired with other plant-based proteins to form a balanced vegetarian or vegan diet. Diets high in plant-based protein have been linked to lower risks of stroke, cancer, and heart disease-related deaths.Very Easy to PrepareOften seen as a healthier alternative to traditional pasta, couscous is made from whole-wheat flour and is quick to prepare. Most supermarket versions are pre-steamed and dried; they only require the addition of boiling water or broth followed by fluffing with a fork. Light and fluffy when cooked, couscous easily absorbs the flavours of other ingredients and pairs well with salads, meats, vegetables, or other grains like quinoa and brown rice.Things You Should Consider Before High in GlutenCouscous is made from semolina, a product of durum wheat, and therefore contains gluten. This makes it unsuitable for individuals with celiac disease or gluten sensitivity.Could Raise Blood Sugar LevelsWith 36 grams of carbohydrates per cup and minimal protein, couscous may cause blood sugar spikes—particularly a concern for those with diabetes or insulin resistance. Combining it with protein-rich foods or those high in soluble fibre can help mitigate this effect.Lower in Some Key NutrientsWhile couscous contains small amounts of fibre, potassium, and other nutrients, it falls short compared to other whole grains like quinoa, oats, or brown rice. Foods such as avocados, bananas, and potatoes are richer sources of potassium, which supports healthy blood flow and may reduce the risk of stroke.The TakeawayCouscous, with its high selenium content, offers several health benefits, including immune support and a potential reduced risk of cancer. However, it may not be suitable for everyone—especially those with gluten intolerance or blood sugar concerns. For those who tolerate gluten, couscous remains a convenient, versatile grain option worth including in a balanced diet.
