Which Vegetable Has the Most Fibre?
Artichokes are a strong answer when comparing familiar vegetables, while green peas also rank highly. The most useful choice depends on portion size and how the food is logged.
The short answer
Artichokes are among the highest-fibre vegetables by weight and can provide plenty of fibre in a typical serving. Green peas are another fibre-rich option, although they belong to the legume family and are often grouped with vegetables in everyday eating.

There is no fixed winner for every meal because comparisons may use a whole vegetable, a spoonful, a serving or a set weight. The exact fibre figure also varies with the variety, preparation method and nutrition database.
Why serving size changes the ranking
A vegetable can look high in fibre per serving simply because its usual serving is larger. Comparing the same weight gives a fairer ranking, while comparing your actual portion is more useful for tracking what you eat.

Raw and cooked entries may also show different values because cooking changes water content and volume. Choose the food-log entry that most closely matches both the preparation and the amount on your plate.
Other fibre-rich vegetables
Brussels sprouts, parsnips, broccoli, carrots and leafy greens can all contribute fibre. Their individual ranking matters less than the total amount and range of vegetables you eat across the day.

Peas are especially easy to add in a noticeable portion, while artichokes may be eaten less often. A slightly lower-fibre vegetable that you regularly enjoy can make a bigger practical contribution than one you rarely choose.
How to track fibre more clearly
When comparing vegetables in your tracker, use the same basis, such as the same weight cooked. Check whether inedible leaves, stalks or pods have been excluded, as these can make the logged weight misleading.

Look at your daily fibre total rather than trying to make one vegetable do all the work. Artichokes and peas are useful high-fibre choices, but variety makes it easier to build fibre into meals you already like.
