Buns can be useful! Even if not just any and not for everyone.

How to reduce the harm
If you really want to eat buns, not to get fat and not to die prematurely, then it is better to look towards flour of a different shade, which has more fiber, protein and vitamins:
Almond
Wheat
Corn
Coconut
Oat
Rye

Brown rice flour reduces the risk of developing cardiovascular diseases, obesity, type 2 diabetes and improves digestion. It is rich in magnesium, selenium, vitamin B6 and phosphorus. Pancakes, fritters and other buns made from such flour will not be so sweet and airy, but they will add health.

WHO recommends consuming five servings, or 400 grams, of vegetables and fruits every day – this reduces all possible health risks. Then you can eat a bun between servings of healthy food.
