Wheat  (Triticum L. ) belongs to the Graminaceae family.

Wheat is a basic ingredient in the human diet and is incorporated into many food products including bread, cereals and pasta.

The main component (60-70%) of wheat is starch, a source of glucose rapidly released during digestion that contains two main glucose polymers, Amylosis and Amilopectin.

With the rise of human health problems such as obesity and diabetes, there has been a growing interest in altering the composition of starch in cereals and increasing the percentage of resistant starch.

Resistant starch is the fraction of starch that escapes digestion in the small intestine (1) and is considered a form of dietary fiber with beneficial health properties (2). Because foods high in resistant starch are digested more slowly, they have been shown to improve insulin response and increase satiety (3).

The advantages of resistant starch also extend to colon health where fermentation occurs in the large intestine (4).

Wheat is used to obtain flours that can be:

• integral type 2
• refined of type 0
• even more refined than type 00

The more refined the flours are, the more they lose their nutritional characteristics.

For example, type 0 is different from 00 because it is less refined in grinding.

Nutritional values:

Pretty caloric with about 337 kcalories per 100 grams.

Saturated fatty acids: 0.4g per 100 grams

It contains less protein than hard wheat that is used for the pasta preparation..
