The products concerned are mainly cereal products (rice, pasta, flour …) but also sugar.
In its raw state, each grain of cereals is a jacket protects rich in micronutrients (vitamins and minerals), and fiber.
Maintaining full or part of this envelope in the food to eat, is a source of ambiguity:
- Intake of vitamins, minerals and fibers give these foods nutritionally very interesting, but its protective role, the envelope and it also focuses residue chemicals (fertilizers, pesticides) … ..
- Phytates in such foods rich in sound, have a positive effect: they have a preventive effect against colon cancer, and an evil action, they would promote the loss of Iron and Calcium …
- In people with “sensitive stomachs”, the fibers are the cause of flatulence, bloating and stomach pain.

Refined foods and prepared

These are foods that undergo many changes. The goals are multiple:
- Facilitate the culinary uses (reduced cooking time …)
- Get rid of their food “impurities” (Chemical Residues …),
- Make food more palatable …
These different operations deplete, significantly, the food micronutrients and fiber. Outside, nutritionists have sounded the alarm: they denounce, in our industrialized countries, the increase of a population with nutritional deficiencies.
On the other hand, these foods are quickly absorbed by the body and do not provide sufficient satiety: the sensation of hunger and its consequences (snacking, lack of concentration …) apparraissent quickly after a meal.
The lack of fiber in the diet is often the cause of constipation. And worse, it encourages the development of gastrointestinal tract cancers: intestinal transit is slowed, therefore, possible carcinogens present, have a prolonged contact, and act on the side wall of the digestive tract.
