Khaberni - Despite the popularity of gut health products, 96% of people in the UK fail to meet the recommended goal of 30 grams of fiber per day.
Dr. Federica Amati, chief nutrition expert at Zoe platform, warns that even health-conscious individuals make critical mistakes that prevent them from fully benefiting from fiber, which include reducing the risk of heart disease, type 2 diabetes, and colon cancer.
"Fiber Washing"
Many ultra-processed foods, such as ice cream or biscuits, add isolated fibers (like inulin) to claim they are "high in fiber". These are often "sales tactics" that may mask unhealthy ingredients and could cause digestive disorders for those with "irritable bowel syndrome".
Overrating "Whole Grains"
Simple changes, like switching from white to brown rice or eating an apple a day, are not enough. Whole grain pasta, often cooked, usually contains less than the minimum fiber (6 grams per 100 grams). “The real heroes” in fiber are lentils, chickpeas, and seeds.
Moving Quickly from "Zero to Thirty"
Increasing fiber intake suddenly and significantly can confuse gut bacteria, leading to bloating and gas. Dr. Amati recommends gradually increasing to allow the microbes to adapt.
Lack of Drinking Water
Increasing fiber without increasing the amount of water (about two liters daily) can lead to constipation. Soluble fibers need water to turn into a gel that softens the stools; without it, the fibers become dry and slow bowel movement.
Lack of Diversity
Eating the same five types of vegetables daily limits the diversity of gut microbes. To support a healthy microbiome, aim for 30 different plants per week, including nuts, seeds, and legumes.
Reliance on Dietary Supplements
Although supplements have their role (such as during travel), they lack the vitamins, minerals, and complex healthy fats found in whole plants.
To truly support metabolism and immunity, focus on affordable whole foods like lentils and beans, rather than costly processed alternatives that claim to contain fiber.
