Oats (Avena sativa) is a type of grain, specifically, the edible seeds of oat grass. It is commonly consumed for breakfast in the form of either oatmeal or rolled oats. Plain oats have a bland taste and a mushy but hearty texture when cooked. It is also added to baked goods and is popular among people who are trying to lose weight.
Quinoa (Chenopodium quinoa) is a grain crop cultivated for its edible seeds. It is considered a pseudo-cereal that has been an important food source in South America since the time of the Incas. Referred to traditionally as the "mother of all grains," quinoa has a nutty flavor and comes in three main types: red, black, and white.
In terms of fat, quinoa contains less. A 100-gram serving of quinoa provides only 2 grams of fat compared with oatmeal, which provides about 7 grams. However, the fats from oatmeal are said to be healthy and include mostly omega-3 and omega-6 fatty acids -- polyunsaturated fats that are good for the heart. Quinoa, on the other hand, contains monounsaturated fat (oleic acid), long-chain saturated fat (palmitic acid), and an essential fatty acid called linoleic acid.
When it comes to calories, oats offers more than thrice the calories quinoa does. Per 100 grams of quinoa, a person can get 120 calories, while the same amount of oatmeal gives 389 calories. Quinoa is recommended over oats when it comes to reducing weight as the calories from quinoa come from protein, dietary fiber, and starch. The calories from oatmeal come from sucrose, starch, and dietary fiber. (Related: Improving digestion: 11 gut-friendly foods.)
While on the subject of carbs, oatmeal provides 66 grams of carbs per 100 grams, 10 grams of which are dietary fiber. Meanwhile, a 100-gram serving of quinoa has about 21 grams of carbs, 3 grams of which are dietary fiber (mostly insoluble). When it comes to proteins, quinoa also has less: Oatmeal contains 17 grams while quinoa only has 4 grams. However, quinoa provides all the essential amino acids needed by the body, particularly lysine. Lysine is not found in most plant-based foods but can be found in oats and large quantities in quinoa.
The mineral content of quinoa and oatmeal is very similar. Both contain calcium, iron, magnesium, manganese, phosphorus, zinc, potassium, and copper. Oatmeal contains more iron, magnesium, and phosphorus than quinoa, while quinoa contains more calcium and manganese. Quinoa also contains selenium, a mineral that boosts the immune system.
In terms of vitamins, oatmeal can provide an equal amount of vitamin B6 but more thiamin (vitamin B1), riboflavin (vitamin B2), folate (vitamin B9), and niacin (vitamin B3) than quinoa. Oatmeal also contains a unique group of antioxidants known as avenanthramides and trace amounts of vitamin K. On the other hand, quinoa is a source of vitamin E, which is not present in oats.
