So when my editor challenged me to eat oatmeal every day for a whole week and share what happened, I couldn\u2019t pass up the opportunity to see what it was like (I already tried <a href=\"https:\/\/www.prevention.com\/food-nutrition\/healthy-eating\/a69030847\/what-happens-when-you-eat-spinach-every-day\/\" target=\"_blank\" data-vars-ga-outbound-link=\"https:\/\/www.prevention.com\/food-nutrition\/healthy-eating\/a69030847\/what-happens-when-you-eat-spinach-every-day\/\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"eating spinach every day\" data-node-id=\"1.1\" class=\"body-link css-1xnf0nh emevuu60\" rel=\"nofollow noopener\">eating spinach every day<\/a>, <a href=\"https:\/\/www.prevention.com\/food-nutrition\/healthy-eating\/a66128487\/what-happens-when-you-eat-apple-every-day\/\" target=\"_blank\" data-vars-ga-outbound-link=\"https:\/\/www.prevention.com\/food-nutrition\/healthy-eating\/a66128487\/what-happens-when-you-eat-apple-every-day\/\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"eating an apple every day\" data-node-id=\"1.3\" class=\"body-link css-1xnf0nh emevuu60\" rel=\"nofollow noopener\">eating an apple every day<\/a>, and <a href=\"https:\/\/www.prevention.com\/food-nutrition\/a69905970\/what-happens-when-you-drink-kombucha-every-day\/\" target=\"_blank\" data-vars-ga-outbound-link=\"https:\/\/www.prevention.com\/food-nutrition\/a69905970\/what-happens-when-you-drink-kombucha-every-day\/\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"drinking kombucha every day\" data-node-id=\"1.5\" class=\"body-link css-1xnf0nh emevuu60\" rel=\"nofollow noopener\">drinking kombucha every day<\/a>). Don\u2019t get me wrong\u2014oatmeal is a part of my breakfast rotation and has been for years. But having it for breakfast every morning is a different story. <\/p>\n<p data-journey-content=\"true\" data-node-id=\"2\" class=\"css-6wxqfj emevuu60\">As oats are nutritious, versatile, and easy to prepare, I figured what could possibly go wrong with a week of oat-filled breakfasts? I was curious: Would I discover something new about this humble grain, or would I confirm what I already tell my clients? Armed with my measuring cup and a healthy dose of skepticism, I set out to find out.<\/p>\n<p>What happened when I ate oatmeal every day<\/p>\n<p data-journey-content=\"true\" data-node-id=\"4\" class=\"css-6wxqfj emevuu60\">My week of oatmeal started with enthusiasm, genuinely excited to see what it would be like to eat this classic breakfast staple every day. As a dietitian, I know the importance of a balanced breakfast, so I made sure to fortify my bowl each morning. I added a scoop of nut butter for healthy fats and protein and a sprinkle of berries for fiber and antioxidants to ensure my meal had staying power, since <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/32768415\/\" target=\"_blank\" data-vars-ga-outbound-link=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/32768415\/\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"protein\" data-node-id=\"4.1\" class=\"body-link css-1xnf0nh emevuu60\" rel=\"nofollow noopener\">protein<\/a>, <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/30166637\/\" target=\"_blank\" data-vars-ga-outbound-link=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/30166637\/\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"fiber, and fat\" data-node-id=\"4.3\" class=\"body-link css-1xnf0nh emevuu60\" rel=\"nofollow noopener\">fiber, and fat<\/a> are the trifecta of nutrients that promote satiety. That sustained energy was one of the first things I noticed. I experienced very few tummy grumbles mid-morning. And at the risk of being TMI, I was very regular during my week-long oatmeal-eating experiment.<\/p>\n<p data-journey-content=\"true\" data-node-id=\"6\" class=\"css-6wxqfj emevuu60\">But to be completely honest, by day five, I was getting a little bored with oatmeal at breakfast-time. There are only so many ways you can dress up a bowl of oatmeal before it starts to feel repetitive. I experimented with different fruits and spices, but the underlying oat-iness was a constant. This experiment was a great reminder that while consistency is key for health, variety is crucial for enjoyment.<br data-node-id=\"6.1\"\/><\/p>\n<p>Oatmeal nutrition<\/p>\n<p data-journey-content=\"true\" data-node-id=\"8\" class=\"css-6wxqfj emevuu60\">Oatmeal&#8217;s reputation as a health food is well-deserved, and the nutritional stats back it up.

This powerful compound has been shown to help lower LDL (bad) cholesterol levels. <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC5810204\/\" target=\"_blank\" data-vars-ga-outbound-link=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC5810204\/\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"Beta-glucan\" data-node-id=\"14.1\" class=\"body-link css-1xnf0nh emevuu60\" rel=\"nofollow noopener\">Beta-glucan<\/a> forms a gel-like substance in the digestive tract, which binds to cholesterol-rich bile acids and helps excrete them from the body. This process forces the liver to pull more cholesterol from the blood to produce new bile acids, effectively reducing overall cholesterol levels.<\/p>\n<p>Lowers blood pressure<\/p>\n<p data-journey-content=\"true\" data-node-id=\"16\" class=\"css-6wxqfj emevuu60\">In addition to boosting cholesterol, oats are a source of antioxidants called <a href=\"https:\/\/www.sciencedirect.com\/topics\/agricultural-and-biological-sciences\/avenanthramide\" target=\"_blank\" data-vars-ga-outbound-link=\"https:\/\/www.sciencedirect.com\/topics\/agricultural-and-biological-sciences\/avenanthramide\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"avenanthramides\" data-node-id=\"16.1\" class=\"body-link css-1xnf0nh emevuu60\" rel=\"nofollow noopener\">avenanthramides<\/a>, which are almost exclusively found in this grain. These antioxidants may <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/34204635\/\" target=\"_blank\" data-vars-ga-outbound-link=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/34204635\/\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"help lower blood pressure\" data-node-id=\"16.3\" class=\"body-link css-1xnf0nh emevuu60\" rel=\"nofollow noopener\">help lower blood pressure<\/a> by increasing the production of nitric oxide. Nitric oxide helps dilate blood vessels, leading to improved blood flow and reduced strain on the heart. <\/p>\n<p>Aids in digestion and gut health<\/p>\n<p data-journey-content=\"true\" data-node-id=\"18\" class=\"css-6wxqfj emevuu60\">The fiber in oatmeal is not just good for your heart; it\u2019s also fantastic for your digestive system. The soluble fiber, beta-glucan, dissolves in water to form a viscous gel that helps regulate digestion. This may reduce the risk of both constipation and diarrhea by improving stool form and consistency. It adds bulk to your stool, making it easier to pass, which promotes regularity and keeps your digestive tract running smoothly.<\/p>\n<p data-journey-content=\"true\" data-node-id=\"19\" class=\"css-6wxqfj emevuu60\">The fiber in oats <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC8697019\/\" target=\"_blank\" data-vars-ga-outbound-link=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC8697019\/\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"acts as a prebiotic\" data-node-id=\"19.1\" class=\"body-link css-1xnf0nh emevuu60\" rel=\"nofollow noopener\">acts as a prebiotic<\/a>. <a href=\"https:\/\/www.prevention.com\/food-nutrition\/a41506061\/best-prebiotic-foods\/\" target=\"_blank\" data-vars-ga-outbound-link=\"https:\/\/www.prevention.com\/food-nutrition\/a41506061\/best-prebiotic-foods\/\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"Prebiotics\" data-node-id=\"19.3\" class=\"body-link css-1xnf0nh emevuu60\" rel=\"nofollow noopener\">Prebiotics<\/a> are compounds that act as fuel for the beneficial bacteria living in your gut. A healthy gut microbiome is essential for everything from nutrient absorption to immune function. By providing fuel for these friendly microbes, oatmeal helps foster a balanced and thriving gut environment, which is a cornerstone of overall health.<\/p>\n<p>Helps with blood sugar management<\/p>\n<p data-journey-content=\"true\" data-node-id=\"21\" class=\"css-6wxqfj emevuu60\">For individuals looking to manage blood sugar levels, oatmeal may be a great addition to your diet\u2014but with some caveats (as oats do contain carbohydrates). It\u2019s important to pair them with healthy fats and protein to slow potential blood sugar spikes, and, of course, avoid adding sugar and sticking to a modest portion. One reason it\u2019s considered ideal for blood sugar is that the <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC9736284\/\" target=\"_blank\" data-vars-ga-outbound-link=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC9736284\/\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"soluble fiber found in oats slows down the digestion\" data-node-id=\"21.1\" class=\"body-link css-1xnf0nh emevuu60\" rel=\"nofollow noopener\">soluble fiber found in oats slows down the digestion<\/a> and absorption of carbohydrates. This gradual absorption may reduce the risk of the sharp spikes in blood sugar and insulin that can occur after eating refined carbohydrates. A more stable blood sugar response is beneficial for everyone, but it is especially important for those with diabetes or <a href=\"https:\/\/www.prevention.com\/health\/health-conditions\/a38595773\/what-is-insulin-resistance-syndrome\/\" target=\"_blank\" data-vars-ga-outbound-link=\"https:\/\/www.prevention.com\/health\/health-conditions\/a38595773\/what-is-insulin-resistance-syndrome\/\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"insulin resistance\" data-node-id=\"21.3\" class=\"body-link css-1xnf0nh emevuu60\" rel=\"nofollow noopener\">insulin resistance<\/a>. <\/p>\n<p data-journey-content=\"true\" data-node-id=\"22\" class=\"css-6wxqfj emevuu60\">The thick gel that beta-glucan forms in the gut is the key mechanism behind this benefit. It <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/31828287\/\" target=\"_blank\" data-vars-ga-outbound-link=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/31828287\/\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"delays stomach emptying\" data-node-id=\"22.1\" class=\"body-link css-1xnf0nh emevuu60\" rel=\"nofollow noopener\">delays stomach emptying<\/a>, meaning the glucose from the meal enters the bloodstream at a much slower, more controlled pace. Combining oats with protein, fiber, and healthy fat may help the meal support healthy blood sugars even more.  <\/p>\n<p>Who should avoid oatmeal?<\/p>\n<p data-journey-content=\"true\" data-node-id=\"24\" class=\"css-6wxqfj emevuu60\">While oatmeal is a healthy choice for most people, it\u2019s not suitable for everyone. Individuals with celiac disease or a non-celiac gluten sensitivity need to be cautious. Oats are naturally gluten-free, but they may be grown and processed in facilities that also handle wheat, a source of gluten. This cross-contamination can introduce gluten into the final product, potentially triggering a reaction. If you must avoid gluten, it is essential to purchase oats that are specifically certified as gluten-free.<\/p>\n<p data-journey-content=\"true\" data-node-id=\"25\" class=\"css-6wxqfj emevuu60\">Additionally, some people with certain gastrointestinal issues, like gastroparesis (delayed stomach emptying), may need to limit their intake of high-fiber foods like oatmeal. The same fiber that provides so many benefits can sometimes worsen symptoms in these specific conditions. As with any dietary change, it is always best to consult with a healthcare provider or a registered dietitian to determine what is right for you.<\/p>\n<p>The bottom line<\/p>\n<p data-journey-content=\"true\" data-node-id=\"27\" class=\"css-6wxqfj emevuu60\">My week-long oatmeal challenge was a good reminder of what I already knew as a dietitian: Oatmeal is a nutritional powerhouse. It kept me full, provided sustained energy, and I had the peace of mind knowing it was supporting my heart and gut health, even if I couldn\u2019t feel it. Eating it every day definitely pushed my creativity in the kitchen, but it also reminded me why it\u2019s such a solid breakfast staple. That said, I\u2019ll admit I can\u2019t eat it every single day without getting bored, so to keep reaping the benefits of beta-glucans, I\u2019ll be mixing in other sources like barley, mushrooms, or even seaweed.<\/p>\n<p data-journey-content=\"true\" data-node-id=\"28\" class=\"css-6wxqfj emevuu60\">I am confident that my body was reaping health benefits during my experiment window without me realizing it. For instance, though I couldn\u2019t physically feel my cholesterol levels improving or the soluble fiber working its heart-health magic, I knew those benefits were quietly taking place behind the scenes. That\u2019s the thing about nutrition\u2014its most powerful effects often go unnoticed in the short term. Did I feel like a completely transformed person after just seven days? Of course not. No single food can be a life-changing miracle, and it\u2019s important to keep that in perspective.<\/p>\n<p>Related Stories<\/p>\n","protected":false},"excerpt":{"rendered":"5 min read As a dietitian, I\u2019m often the one encouraging others to give oatmeal a regular spot&hellip;\n","protected":false},"author":2,"featured_media":308089,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[36],"tags":[1977,144818,1107,103,61,60,1106,446,144817],"class_list":["post-308088","post","type-post","status-publish","format-standard","has-post-thumbnail","category-nutrition","tag-content-type-how-to-service","tag-contentid-b990998c-3614-48ee-a535-ee965053f53e","tag-displaytype-standard-article","tag-health","tag-ie","tag-ireland","tag-locale-us","tag-nutrition","tag-shorttitle-what-happened-when-i-ate-oatmeal-every-day"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/308088","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/comments?post=308088"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/308088\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media\/308089"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media?parent=308088"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/categories?post=308088"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/tags?post=308088"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
