More the wheat is processed, lower is its nutritional value. Remember that the packed cereals like muesli and wheat flakes which have gone through rollers have in the process lost most important part of the grain and only give you a false satisfaction of having eaten healthy.
Refined wheat and grains are high in carbs that get digested and absorbed very quickly, leading to rapid spikes in blood sugar and subsequent hunger and cravings. They are linked to obesity and many metabolic diseases.
Do not get distracted by food fads and eat less processed flours and more of whole wheat products.
