Eat a Fiber Rich Diet

Various studies evidence a high intake of dietary fiber associated with numerous benefits for gut health. The NIH data records that adults should consume at least 25-30 grams of fiber each day. As a matter of fact, no more than 5% of the populace achieves this criterion. Several studies have demonstrated that if intakes go above 25 grams per day, the risk for hypertension is decreased by 15% or more. In 2022, the demand for high-fiber foods in the global market grew by 8.5%, especially in the European and American markets. In particular, the value of high-fiber foods has increased from $12 billion in 2018 to $13.5 billion in 2022 and is expected to see further growth at an annual rate of 7% through 2028. With consumers being more concerned about gut health, whole grains, vegetables, and fruits rich in fiber are gradually becoming mainstream choices in the market. Among them, the annual growth rate of whole grain foods has already surpassed 10%. For more details on body’s antioxidant defenses, visit the link. The increase in dietary fiber lowers the incidence of constipation. With a mere 5 grams of increased intake of dietary fiber each day, studies say the incidence of constipation decreases by as much as 28%. According to the Journal of Clinical Nutrition of the United States, an increase in intake by every 10 grams makes the possibility of weight loss rise by 4%. According to the IDF, for every 10-gram increase in soluble fiber intake, there is a 14% reduction in the risk of developing diabetes. Dietary fiber intake lowers the risk for heart disease. For every additional 10 grams of fiber consumed per day, there is a 17% decrease in the rate of deaths from coronary heart disease. Fiber works to lower the risk of heart disease by preventing the absorption of cholesterol in the gut, thereby reducing LDL cholesterol levels. A 2023 survey in the United States showed that over 70% of adults do not meet the recommended fiber intake. Experts recommend increasing fiber intake gradually through simple dietary adjustments, such as replacing white bread with whole wheat bread or oatmeal for breakfast, or adding fiber-rich foods like legumes and nuts. In fact, some foods have a remarkable fiber content. The amount in one serving of cooked black beans, about 15 grams, comes close to the upper recommended daily intake. For example, one medium-sized apple contains 4 grams of fiber and one carrot contains 3 grams of fiber.

Diversify Your Diet

A 2020 study published in the Journal of Clinical Nutrition found that the consumption of more than 20 types of foods every day could effectively improve gut microbiota diversity. Those with high dietary diversity had a diversity in beneficial gut bacteria that was more than 30% higher. The European Journal of Cardiology published a report in 2021 that proved a fact: increasing the proportion of plant-based foods such as vegetables, nuts, and legumes decreases the incidence of cardiovascular diseases by up to 30%. With consumption of an extra 25 grams of more diverse vegetables and nuts every week, the risk of heart attack decreases by about 3-5%. A 2019 study published in the Journal of Obesity and Metabolism Research showed that with a high variety index of foods, the percentage of body fat and the contents of abdominal fat were approximately 1.5 kg less in subjects with high food diversity than in those with one habitual diet. A diversified diet based on fruits, vegetables, whole grains, and high-quality proteins can help diabetic patients decrease their HbA1c by 2-3 units, according to a study in the Journal of Diabetes and Metabolic Syndrome in 2022.

The demand for plant-based protein-rich foods grew by almost 18%. A review study published in the Journal of Psychiatry and Psychology Research in 2020 showed that a diversified diet, especially one rich in omega-3 fatty acid-rich fish, nuts, and fiber-rich foods, can reduce the incidence of depression by 20%. Individuals with high food diversity have a 20% higher mental health index. The researchers who authored that study found out from a research base in 2021 through the Journal of Environmental Research, a 10% increase in plant-based food means carbon emission reductions by around 4.5 percent.

Limit Processed Foods

A 2019 study released by the American Heart Association pointed out that high-sugar and high-salt processed foods are major risk factors for cardiovascular diseases and recommended reducing the intake of processed foods by at least 20% annually. Reducing the intake of processed foods can lower the risk of heart attacks by about 4-6%. A global survey in 2020 showed that reducing the intake of trans fats by 50% decreased the incidence of certain cancers by approximately 15%. Research from the National Cancer Institute (NCI) in the United States further confirmed that after reducing highly processed meat products, the incidence of colorectal cancer decreased by 7-10%. Reducing the weekly intake of processed meats by 200 grams can lower the probability of developing colorectal cancer by about 8%. A 2021 study published in the Journal of Diabetes Care indicated that reducing the intake of added sugars and refined starches in processed foods can effectively lower the incidence of type 2 diabetes. Reducing the consumption of processed snacks by three times a week can decrease the incidence of diabetes by 6-8%. According to a 2022 study in the Journal of Digestive Diseases and Gut Microbiology, reducing the intake of over 50 grams of processed sugars and processed foods daily can improve the structure of the gut microbiota. A long-term study published in the Journal of the American Medical Association indicated that teenagers who consumed processed foods more than twice a week had an obesity rate that was 25% higher than those who did not consume processed foods. According to a 2020 survey by Consumer Reports, American households spend about $1,500 annually on purchasing processed foods. If these expenses are shifted to fresh fruits and vegetables, whole grains, and unprocessed foods, about $400 to $500 can be saved each year. In 2021, the United Nations released the Global Food Policy Report, stating that reducing the consumption of processed foods is a core strategy for improving public health and reducing diseases such as obesity and diabetes globally.
