Understanding the 'One Portion' Rule for Kidney Beans
Yes, kidney beans absolutely count towards your daily intake of fruits and vegetables, but with a specific rule that often catches people by surprise. The UK's National Health Service (NHS) and other health bodies confirm that beans and pulses, including kidney beans, only count as a single portion towards your 5 a day, no matter how large a quantity you consume. This guideline exists because pulses, while rich in fibre and protein, contain a different profile of vitamins and minerals compared to a typical fruit or vegetable portion.
Why are Beans and Pulses Limited to One Portion?
The primary reason for this limitation is nutrient diversity. A key principle of the 5 a day recommendation is to consume a variety of fruits and vegetables to benefit from a broad spectrum of nutrients. While kidney beans are a fantastic source of plant-based protein and dietary fibre, they do not offer the same mix of vitamins and minerals found in, for example, a handful of spinach or a ripe orange. Therefore, relying on beans alone for multiple portions would mean missing out on the diverse nutritional benefits that other produce provides.
Correct Portion Size for Kidney Beans
A standard adult portion of beans or pulses is 80g, which is equivalent to approximately three heaped tablespoons of cooked kidney beans. This means if you add three or more tablespoons of kidney beans to a chilli, you have successfully logged one of your 5 a day portions. However, eating six tablespoons in the same meal will still only count as one portion, not two. This rule ensures you seek variety across your remaining portions from other sources.
Incorporating Kidney Beans and Other Pulses into Your Diet
Beans and pulses are incredibly versatile and are a great way to boost your fibre and protein intake. Here are some practical ways to include them in your meals without over-relying on them for your 5 a day target:
- Chilli and Stews: Bulk up meat or vegetable-based stews and chillies with a can of kidney beans. This adds texture, fibre, and a rich, hearty flavour. Since you're also likely adding tomatoes, peppers, and onions, this single dish can contribute multiple portions.
- Salads: Add a handful of kidney beans to your lunchtime salad. Combined with a bed of leafy greens, tomatoes, and cucumber, this can make for a filling and nutritionally dense meal.
- Burgers and Patties: Create homemade veggie burgers using mashed kidney beans as a base. Mix them with breadcrumbs, herbs, and spices for a delicious alternative to meat.
- Dips and Spreads: While hummus is typically made with chickpeas, you can experiment with other bean varieties. A blended dip with kidney beans, garlic, and spices can be a great snack with vegetable sticks.

Expanding Your 5 a Day Beyond Pulses
To ensure you're getting a wide range of nutrients, it's essential to diversify your fruit and vegetable intake beyond pulses. Think about incorporating different colours and types of produce throughout your day. A plate rich with a variety of colours is often a good indicator of a varied diet. Examples of other items that count include frozen fruit and vegetables, canned fruit in juice or vegetables in water (no added salt or sugar), and even the produce cooked into sauces or ready meals.

Conclusion: The Final Word on Kidney Beans and Your 5 a Day
In summary, kidney beans are a nutritious and valuable part of a healthy diet, providing a great source of fibre and protein. They do indeed count as one of your 5 a day, but this contribution is limited to a maximum of a single portion daily. To achieve a truly balanced diet, you should combine them with a diverse array of other fruits and vegetables. By understanding this guideline and focusing on variety, you can use kidney beans as a powerful tool to make your meals healthier and more filling, while still exploring the full spectrum of produce available. Remember the 80g rule (three heaped tablespoons), enjoy your beans, and fill the rest of your portions with a colourful mix of other fruits and vegetables throughout the day.
