Is Quinoa Keto-Friendly? Discover the Truth About Quinoa on a Low-Carb Diet!

Contrary to common belief, incorporating some grains into a ketogenic diet is possible, but where does quinoa stand? While the keto diet is characterized by low-carb and high-fat intake, not all grains are off the table. This article delves into the question: Is quinoa keto-friendly? It explores quinoa's nutritional profile, carbohydrate content, and potential impact on ketosis, while also providing a list of low-carb alternatives.

What is Quinoa?

Quinoa, often grouped with grains, is actually a seed harvested from the Chenopodium quinoa plant, related to spinach and beets. Although technically a seed, quinoa is considered a healthy whole grain that’s naturally gluten-free. It has been around for thousands of years, mostly enjoyed by ancient civilizations like the Incas. Today, quinoa is a popular choice for people who want to add a nutritious, plant-based food to their diet.

Nutritional Profile of Quinoa

What makes quinoa special is its nutrient profile. Quinoa is widely regarded as a nutritional choice as it contains all nine essential amino acids, making it a complete source of protein. Some of the micronutrients in quinoa include copper, magnesium, phosphorus, manganese, and vitamins E, B6, and folate. It also contains monounsaturated and saturated fats that have been found to support heart health and reduce the risk of heart disease. Additionally, quinoa is a source of B vitamins and essential minerals, including calcium, magnesium, phosphorus, and potassium.

The Keto Diet: A Quick Overview

Before we get into whether quinoa fits into the keto lifestyle, let's quickly remind ourselves of what a keto diet is all about. The keto diet is an extremely low carb, high fat diet. The goal is to achieve a metabolic state of ketosis, in which your body burns mostly fat instead of carbs for energy. Ketosis is achieved by restricting carb intake to between 20 and 50 grams of net carbs daily. This helps stabilize blood glucose and insulin levels, which pushes the body to use fat instead of sugar to generate energy for the cells.

On a 2,000-calorie diet, a keto diet will typically be composed of:

Fat: 55% to 60%
Protein: 30% to 35%
Carbs: 5% to 10% carbs

Is Quinoa Keto-Friendly? The Carbohydrate Content

Due to its high carbohydrate content, quinoa isn’t keto-friendly and can quickly disrupt fat-burning and nutritional ketosis.

Quinoa is considered a fairly high carb food, as it contains 21.2 grams in a cooked 3.5-ounce (100-gram) serving. This gives it roughly the same number of carbs as millet. A 1-cup serving of cooked quinoa has more than 39 grams of carbohydrates. That’s 50% more than in the same amount of brown rice and almost as many carbs as in white rice.

Although quinoa ranks low on the glycemic index, which measures how quickly a specific food raises blood sugar levels, a typical serving size contains 17.2 g of net carbs.

Quinoa can quickly surpass your daily net carb limit and disrupt fat-burning, slowing down or inhibiting the health benefits of ketosis, including weight loss, better glycemic control, and improved insulin sensitivity.

The Glycemic Index of Quinoa

Quinoa has a glycemic index of 53, which is a measure of how quickly it will raise your blood sugar levels. That score puts quinoa in the middle range of “good” vs. “bad” carbs. However, it still acts similarly to other grains by spiking blood sugar levels and can quickly bump you out of ketosis.

Potential Drawbacks of Quinoa

However, similar to other grains and seeds, quinoa contains anti-nutrients such as phytic acid and enzyme inhibitors, which can interfere with digestion and cause discomfort or inflammation in the gastrointestinal tract. Despite its nutritional benefits, these anti-nutrients also limit the absorption of key vitamins and minerals, diminishing quinoa’s overall nutritional value.

Including Quinoa in a Keto Diet: Considerations

If you still want to include quinoa in your keto diet, consider it a garnish rather than a central part of your meal. If you’re planning on including this grain in your keto or low carb diet, you should only do so sparsely - not in full-sized portions.

You may try switching to quinoa bread or pasta instead of wheat to see if it eases your gastrointestinal symptoms.

Smaller Portions: Instead of going for a full cup of quinoa, try a smaller portion to keep your carb count in check. Mix with Low-Carb Foods: Quinoa doesn’t have to be the star of your meal. You can mix it with other low-carb foods to balance out your plate. Track Your Carbs: If you’re on a keto diet but still want to include quinoa, it’s essential to track your daily carb intake.

Keto-Friendly Quinoa Alternatives

Finding low-carb grain alternatives can be tricky for those new to the ketogenic diet. Fortunately, there are several keto-friendly options that mimic quinoa’s taste and texture without the added carbs.

Cauliflower rice: Chopped cauliflower is one of the most popular rice and grain substitutes for keto dieters. Cauliflower’s versatility and mild flavor allow it to be used in a variety of cuisines while offering a robust nutritional profile, including disease-fighting antioxidants, essential minerals, and fiber. Cauliflower rice can replace quinoa in burrito bowls, salads, soups, and Asian-inspired dishes, such as this keto Cauliflower Fried Rice recipe.
Mushroom rice: Mushroom rice is another keto-friendly quinoa alternative packed with umami flavor that is perfect for Asian-inspired recipes or alongside hearty proteins, such as fish, grass-fed steaks, or chicken. Combine mushroom rice with sautéed garlic, caramelized onions, or fresh herbs for a deeper flavor that pairs well with any savory dish.
Cabbage rice: Cabbage rice is made from tiny shreds of cabbage and is often sautéed in oil and seasoned similarly to quinoa, rice, and other grains. Cabbage is an excellent quinoa alternative, rich in vitamin C and anti-inflammatory compounds that may lower cancer risk and help protect from cardiovascular and neurodegenerative diseases.
Broccoli rice: Broccoli is a health-promoting cruciferous vegetable that can be shredded and used in place of quinoa. Due to its more noticeable flavor, broccoli rice is typically paired with complementary foods such as beef, cheese, and salmon. It’s also an excellent option for casserole recipes that call for quinoa.
Shirataki rice: Shirataki rice is cultivated from an Asian root vegetable called konjac. It’s a low-carb alternative primarily composed of water with a neutral flavor, perfect for replacing quinoa in savory and sweet dishes. Shirataki rice also has a texture similar to cooked quinoa, with a gelatin-like bounce and mouthfeel.
Chia seeds: Quinoa is often added to breakfast bowls for extra fiber and protein. Chia seeds are an excellent alternative, offering a similar texture when soaked in water, which works well in puddings, smoothies, salads, and keto baked goods. Additionally, chia seeds are nutrient-dense and rich in omega-3 fatty acids, vitamin C, B vitamins, and minerals linked to cardioprotective benefits and improved brain health.

Foods to Limit on the Keto Diet

Here are some foods to limit if you’re following a ketogenic diet.

Bread, pasta, rice, and other refined carbs: Eating refined high carb foods may prevent a ketogenic state if you consume more than your daily carb allowance. Try mashed or riced cauliflower as a substitute, or experiment with low carb bread made from eggs, nuts, and seeds.
Glazed or honey-baked ham: While delicious, the sugar baked onto or infused into these sweetened hams can keep you from reaching or maintaining ketosis. Instead, opt for regular deli ham, which has less than 1 g of carbs per slice (13.5 g).
Potatoes and other starchy vegetables: Starchy vegetables are usually limited on the keto diet due to their high carb content, despite their other nutritious benefits. Non-starchy vegetables like spinach, mushrooms, tomatoes, cucumber, and celery are usually better suited for keto diets.
Sweetened yogurt or dairy: When adding dairy to your diet, steer clear of flavored or sweetened varieties, which will add to your carb count. Aim for plain, full fat yogurt or cottage cheese. Unsweetened almond milk may be a better option for keto diets.
Certain fresh fruits: Some fruits may be higher in carbs than others, which could keep you from reaching or maintaining ketosis. If you’re still craving more fruit, reach for keto-friendly fruits like berries, avocado, raspberries, unsweetened açaí puree, watermelon, and coconut.
Beans and other legumes: Some legumes and beans may be challenging to incorporate into your keto diet due to their high carb content. You can also try non-bean-based dips like baba ganoush or guacamole.
Alcohol drinks: Beer, liqueurs, and mixed liquor-based drinks have a high carb and low nutrient count, which makes them foods to limit on a keto diet. Consider lower carb drinks like red wine or spirits.
Juice: Consider eating whole fruits instead of consuming high carb, low fiber juices to help maintain ketosis.
Sugary sodas: Sodas are essentially bubbly sugar water that provides zero nutrition and a high carb count. Some beverages to consider drinking instead include: sugar-free soda (though only occasionally), sparkling water with a slice of cucumber, lemon, or lime, still water, unsweetened tea.
Honey and syrups: Honey and syrups like agave or maple are concentrated sugars, so they can easily increase your daily carb count without otherwise providing significant nutrition.
Ketchup, barbecue sauce, and other condiments: Instead, reach for hot vinegar-based sauces, mayonnaise, mustard, or the spice jar if you want to add more flavor to your food without adding to your daily carb count.
Low fat diet foods: Remember, the keto diet aims to be high in fat to provide your body with energy, so full fat options are the better choice.
Light or low fat margarine: Instead, consider reaching for unsalted butter or moderate servings of regular margarine.
Dried fruit or trail mix: Instead, aim for fresh berries to satisfy your sweet tooth.
Chocolate: Look for chocolate that is more than 70% cacao and is low in added sugar. Or, consider dark chocolate made especially for keto diets.

Potential Nutritional Risks of Keto

Because of keto’s restrictions, people on the diet are often at risk of deficiencies in essential nutrients, such as B vitamins, vitamin D, calcium, selenium, magnesium, and vitamin C. To cover your nutrient bases, talk to a registered dietitian who is knowledgeable about keto before starting.
