Chia seeds vs. common fruits and vegetables: Which has more fibre; NHS surgeon reveals surprising list

Think you’re getting enough fibre from your daily salads, fruits, or vegetables? You might be surprised. Dr Karan Rajan, an NHS surgeon and health educator, recently shared that many commonly eaten foods believed to be fibre-rich actually contain very little. “Not all fibre is equal,” he explains, highlighting that a single tablespoon of chia seeds provides around 5g of fibre—ten times more than 100g of cucumber. Even half an avocado delivers five times more fibre than lettuce. Understanding which foods are low and high in fibre is key to meeting daily fibre requirements and supporting digestion, heart health, and overall wellness.Do you eat cucumber, tomato, lettuce, salads, watermelon, or apple daily and assume your fibre intake is sufficient? You might be surprised. Dr Karan Rajan, an NHS surgeon and health educator, recently highlighted on Instagram that some commonly consumed fruits and vegetables thought to be high in fibre actually contain very little.“Not all fibre is equal,” Dr Rajan explained. Many people rely on salads or fruit for fibre, assuming it’s enough to meet daily needs. However, the actual fibre content varies significantly between foods. For example, 100g of cucumber provides just 0.5g of fibre, whereas a single tablespoon of chia seeds delivers around 5g—ten times more. Similarly, half an avocado contains about 6g of fibre, roughly five times more than 100g of lettuce.Even a full plate of salad consisting of lettuce, cucumber, and tomato contains only 2.9g of fibre. By contrast, 100g of raspberries provides over 6g of fibre, more than twice the fibre of that salad. These examples clearly show that while many foods are healthy, not all contribute equally to daily fibre intake.Fibre plays a vital role in digestion, heart health, blood sugar regulation, and weight management. Yet, over 95% of people do not meet the recommended daily fibre intake. This makes being intentional about high-fibre foods crucial for long-term health.Dr Rajan explained that you don’t need to rely solely on high-fibre foods. Instead, combining low- and high-fibre options can help balance nutrition while boosting fibre intake. Small tweaks, such as swapping peeled fruits for whole fruits, can significantly increase daily fibre consumption. For instance, eating a whole apple rather than a peeled one adds an extra gram of fibre, contributing to daily goals. Pairing fibre-rich foods with adequate hydration and regular physical activity further supports digestion, prevents constipation, and promotes overall gut health, making dietary changes more sustainable in the long run.Similarly, incorporating legumes, lentils, and beans into meals not only increases fibre but also adds protein, micronutrients, and sustained energy. For example, 100g of cooked black beans provides 8.7g of fibre—enough to cover a significant portion of the recommended daily intake. By consciously selecting a mix of low- and high-fibre foods, you can optimise both nutrition and fibre intake.There are practical ways to increase fibre in everyday meals. Dr Rajan recommends adding small amounts of nuts or seeds to salads, breakfast bowls, or snacks. For example, sprinkling a handful of nuts or seeds on a salad can add around six grams of fibre, nearly tripling the fibre content of that meal. Chia seeds, flaxseeds, and pumpkin seeds are particularly high in fibre and easy to incorporate.Other strategies include:By making these intentional adjustments, it’s possible to significantly increase fibre intake without drastically changing your diet. This approach ensures you receive both fibre and essential nutrients, supporting digestion, satiety, and overall wellness.Fibre isn’t just about digestion, it’s a cornerstone of a healthy diet. Knowing which foods are high in fibre and learning how to combine them strategically allows you to “fibre max” your meals, improve gut health, and meet daily nutritional needs more effectively.Disclaimer: This article is for general informational purposes only and is not a substitute for professional medical advice, diagnosis, or treatment.
