A high-fiber diet is associated with reduced risks of cardiovascular disease, cancer, death, and improved overall health symptoms.<\/p>\n

It helps in weight management by providing a lasting feeling of fullness. (1) A high fiber diet has been linked to a reduced risk of type 2 diabetes, cardiovascular disease, and certain types of cancer.<\/p>\n If you don’t want to die young, eat fiber.<\/p>\n \u2014Dr. Layne Norton<\/em><\/cite><\/p><\/blockquote>\n A lot of evidence highlights the role of fiber in improving many health symptoms in different people. Comprehensive reviews under the umbrella of multiple meta-analyses provide a wide range of information and recommendations. Analyzing data from 17,155,277 participants, it examines the effect of fiber on heart disease, cancer, mortality, and various other health indicators. (2)<\/p>\n Research has shown that strong, high evidence showing that increasing dietary fiber significantly reduces the risk of heart disease and related mortality.<\/strong>. In umbrella studies, researchers categorize findings by assigning quantitative ratings to different levels of evidence:<\/p>\n Scientists have found compelling evidence that fiber intake is associated with a reduced risk of heart disease, pancreatic cancer, and diverticular disease. <\/p>\n “Diverticular disease … is when parts of the intestine form pouches where food can get trapped and cause severe inflammation,” explains Dr. Norton. <\/p>\n During the study, scientists identified two pieces of evidence linking fiber intake to reduced all-cause mortality. Their findings suggest so eating fiber lowers the risk of heart disease and ovarian cancer<\/strong>. <\/strong><\/p>\n Not stage one, but stage two…there is strong evidence to suggest a beneficial effect.<\/p>\n \u2014Dr. Layne Norton<\/em><\/cite><\/p><\/blockquote>\n Third-class evidence shows potential benefits across 16 different outcomes. Meanwhile, level four evidence, considered weak, shows benefits in six additional outcomes.<\/p>\n Many studies on fiber intake and health consistently show that high fiber consumption is linked to a reduced risk of various health problems. This represents a dose-response relationship, where greater fiber intake leads to greater benefits<\/strong>. <\/p>\n One study showed that for every 10 grams of fiber increase, the risk of death decreased by 10%.<\/p>\n \u2014Dr. Layne Norton<\/em><\/cite><\/p><\/blockquote>\n Dietary fiber is seen as a biohack for longevity. It is consistently linked to a lower risk of death in various groups, including those with type 2 diabetes, cancer, and heart disease.<\/p>\n The researchers confirmed that a A high fiber diet is associated with a reduced risk of stroke<\/strong>. (3) Across multivariate statistical models, people who consumed less than 10 grams of fiber per day faced a 20% to 25% higher risk of stroke compared to those who consumed 10 to 18 grams daily. <\/p>\n Eating dietary fiber reduces the risk of death in people who have had a stroke. Consuming 10 to 18 grams of fiber daily is associated with a 20% to 30% lower risk of death. Increasing fiber intake above 18 grams enhances this benefit, reducing the risk of death by 30% to 40%. <\/p>\n Including more fiber in your diet can contribute to a longer, healthier life and improved overall well-being. “I’m not even talking about the benefits of the gut microbiome. Fiber is the biggest defense you can take for a healthy gut microbiome,” says Dr. Norton. <\/p>\n Claims by carnivore enthusiasts that fiber causes inflammation are questionable, as studies involving fiber-eating participants did not measure C-reactive protein (CRP) levels to support such assertions. “Some fiber-rich foods and abdominal pain are not the same as inflammation. They are not the same,” explains Dr. Norton.<\/p>\n Avoiding sources that may trigger intestinal discomfort is best for people who are sensitive to certain types of fiber. “To live longer, have a higher quality of life, reduce the risk of type 2 diabetes, cardiovascular disease, and cancer, you must eat enough fiber,” said Dr. Norton. “Aim for at least 20 grams of fiber every day as the optimal minimum. Get about 14 grams of fiber per 1,000 calories you eat.” <\/p>\n Fiber can be found in a variety of foods, including fruits, vegetables, whole grains, beans, and grains. “I’m not talking about lucky charms or fruit loops,” explains Dr. Norton. “I’m talking about cereal fiber that can be present in morning cows.” <\/p>\n Whole grains are a source of fiber that has been shown to significantly reduce the risk of heart disease.<\/p>\n Featured image via Shutterstock\/Antonina Vlasova<\/em><\/p>\n<\/div>\n\n","protected":false},"excerpt":{"rendered":" A high-fiber diet is associated with reduced risks of cardiovascular disease, cancer, death, and improved overall health symptoms.
