It's a great source of fiber.
"Oatmeal is one of the healthiest breakfast choices you can make, namely because oats are a great source of fiber," says Brenda Braslow, MS, RD for MyNetDiary. "One cup of cooked old-fashioned oats offers 10 grams fiber and it's mainly soluble fiber, which is the type of fiber that has been shown to lower LDL (bad) cholesterol and blood sugar. Old-fashioned oatmeal helps keep your digestive system functioning well and fiber is also great for keeping you satisfied longer and can therefore help with weight management and loss."
"Oats also offer a decent amount of protein with just one cup of cooked old-fashioned oats containing approximately 10 grams of protein," says Braslow. "Protein, along with fiber, can keep you full longer. Oatmeal is a nutrient-dense food, offering other vitamins and minerals, such as iron, calcium, and magnesium."
Here are 7 Amazing Benefits of Eating Oatmeal.
It may cause some belly bloat.
"If you are new to oats, they may cause bloating so it's best to start with a small portion," says Lisa Young, PhD, RDN and author of Finally Full, Finally Slim.
"Whole grains such as wheat and oats contain high fiber, glucose, and starch," says Shannon Henry, RD for EZCare Clinic. "All of them are consumed by bacteria in the gut or large intestine which leads to gas and bloating in a few people. To lessen the side effects, start with a small quantity and increase gradually to the chosen amount. When you will start eating oat bran, the harmful outcomes from your body will probably disappear."
It can cause weight gain if you're not careful.
"Finally, eating a jumbo serving of oatmeal can lead to weight gain," says Young. "And watch the toppings—a tablespoon or two of crushed walnuts or flaxseeds is great but too much butter or sugar isn't."
"People typically want their oatmeal to be sweeter so as not to eat a boring meal," says Dr. Gan Eng Cern. "They achieve this by adding sugar, chocolate chips, and other sweet food items which ultimately decreases oatmeal's overall nutritional value as these additions throw in extra calories, fat, sugar, carbs."

But it can also help you lose weight—if prepared properly!
"Oatmeal's fiber and nutrients have also been connected with weight loss. These characteristics keep the consumer feeling full which can prevent overeating on calories throughout the day," says Trista Best, MPH, RD, LD a registered dietitian at Balance One Supplements. "It is easy to add antioxidant-rich ingredients into your diet when you eat oatmeal regularly. Dried fruit, nuts and seeds, and nut butters are rich in micronutrients that support most health and wellness goals."
It can help you to feel full.
"Oatmeal is a whole grain that is high in fiber, especially soluble fiber," says Emily Danckers, MS, RD. "When you eat soluble fiber, your digestion is slowed down which can also increase feelings of fullness."
"Consistently eating a high fiber breakfast food like oatmeal, especially when pairing it with a protein and/or fat like some nuts, often keeps people full for hours," says Rachel Paul, PhD, RD, CDN. "They can then concentrate on their work and other items, before thinking about the next meal. Having a go-to, filling breakfast option like oatmeal creates consistency in one's life."
It can decrease your LDL "bad" cholesterol.
"By eating oatmeal every day, you can lower your total cholesterol level, reduce the 'bad' LDL cholesterol, and increase your 'good' HDL cholesterol levels," says Megan Byrd, RD. Byrd recommends even adding oatmeal into your treats, like her favored Oatmeal Protein Cookies recipe.
It can help you in the bathroom.
"Oatmeal's fiber content contributes to positive gastrointestinal health, including having regular bowel movements," says Amy Goodson, MS, RD, CSSD, LD, and author of The Sports Nutrition Playbook. "It's important to increase your fluid intake as you increase your daily fiber intake."
It can control your blood sugar levels.
"Eating oatmeal every day can also help control your blood sugar because it's so high in that fiber," says Byrd. "It helps to slow down the speed at which the carbohydrates in your diet reach your bloodstream, making your blood sugar levels more even during the day. Oatmeal really is a superfood, and one that definitely can be eaten every day!"
