In my opinion, the functional foods are foods that contain nutrients that with special function about health (maybe some of them could prevent certain disease but most of them are not proven by authoritative scientists or bureau like USDA). In reality, I have accepted the concept of functional food for decades from many advertisements on TV. J, now, do you think if the functional foods could really play positive effects on health? I think yes.
There are really some functional foods around us which are useful but few impressed by us. For example, the dark green and red or orange vegetables are good functional foods, because they contain a lot of carotenoids, which can neutralize free radicals and protect against vision problems and skin cancers, but the research of the mechanism of its function is now underway. Besides, the berries, red wine and tea are also functional foods because they contain a lot of flavonoids which can also decrease the amount of free radicals.

Fibre-a helpful nutrient often neglected by most people
As we know, fibre mostly comes from the skeletal system of plants. Formerly, people dislike eating the tissue which is rich in fibre like stem of vegetable, but in fact, the fibre is now esteemed a helpful nutrient for health, especially for these patients who are often suffered from diarrhea.
Like me, the diarrhea troubles me often especially when eating unclean food. Because the dietary fibre cannot be digested by enzymes or other digestive secretions in the alimentary canal, and it promotes more frequent bowel movements and softer stools having increased weight. The softness of stools is largely due to the presence of emulsified gas which is produced by the bacterial action on the fibre.
So it makes other food go through the gut slowly and the nutrients could be absorbed more, and then the function of gut would be enhanced. At the same time, it helps in relieving the constipation which is the main cause of several acute and chronic diseases.
In a word, dietary fibre plays an important role in the maintenance of health and prevention of diseases.
