Products like Kellog's all bran are the highest but be careful. Fibre has two types, soluble and non-soluble all bran belongs to the first group. It is not recommended just to sprinkle all bran on everything as in its own right it lacks other nutrients. Eating too much of one sort every day can cause its own problems. Whilst there may be 'high fibre' foods such as seeds, nuts, bran or a combination in wholemeal breads etc, it is important to obtain fibre from different sources and 24grm per day is recommended. Sorry to be boring but this means the good old answer of a variety of fruit and veg along with nuts, seeds and wholemeal bread is the only way to satisfy the body's requirements. Try as a staple per day four slices wholemeal bread (11) one third can of baked beans (7) a pear with skin (3.5) and an orange or apple (2). Mix this up with other veg, fruit, nuts and pulses and you can't go wrong. Snack on dried apricots or Prunes (5gr for just 3 whole) instead of fatty crisps and chocolate and you can very easily and pleasantly get all the fibre you need, but increasing fibre mean you need to increase water intake also or unpleasant symptoms including constipation could still occur. Also increase fibre gradually or other unmentionable side effects may occur

Fiber in food can be tested using various methods such as gravimetric analysis, enzymatic analysis, or infrared spectroscopy. These methods involve isolating the fiber component from the food matrix and quantifying it based on specific characteristics. It is important to follow standardized protocols and validate the test methods to ensure accurate and reproducible results.
To include more fiber into your diet mostly all you have to do is get and eat food with the highest amount of fiber.
