Oats are a cereal and only the seed is consumed for human consumption, both whole and dehusked. The main chemical constituents of oat seeds are: starch (> 70%), fiber, protein and fat; as regards the secondary compounds, on the other hand, the following emerge: lecithins, vitamins and mineral salts.
Oat bran is rich in trigonellina or avenin (pyridine alkaloid with a neuro-muscular stimulating function); the leaves contain triterpene saponins, while all the aerial parts are rich in gramine (indole alkaloids with calming function); the stramentum (straw) is instead characterized by the presence of pectins and silicic acid. These latter components are essential in the various herbal applications of the oat plant, mainly used against asthenia, physical exhaustion and seborrheic dermatitis (in the latter, the external use of the stramentum).
Like most cereals, oats have also been negatively affected by the stance of corn, rice and wheat. Zona) are emphasizing its nutritional properties again.
Nutritional values (per 100 g of edible portion)
The "oats" are mainly consumed: whole seeds, hulled seeds, oat flakes, oat flour and oat milk.
It should be remembered that, although oats have excellent nutritional characteristics, their bran is less valuable (so to speak ...) than that of wheat.
) is obtained by milling whole or hulled seeds.
Oatmeal is used for the formulation of baked products, but often it must be mixed with wheat powder for correct leavening. Oatmeal lends itself more to dry processes such as biscuits. The most famous recipe based on oats is undoubtedly the Porridge, a breakfast food of Anglo-Saxon origin.
Oats are NOT a cereal that can be integrated into the glute-free diet. To tell the truth, its relevance in the diet of celiacs is still the subject of controversy, as almost all celiacs tolerate it brilliantly. On the other hand, for safety, the same "Ministry of Health" allows it to be taken ONLY in the absence of intestinal compromises (mucosal hypertrophy) and in any case in absolutely limited portions (50g for adults and 25g for children).
The chemical characteristics of non-wholemeal oatmeal will be described below.
Compared to that of the "noblest" cereals, oat flour has different nutritional properties. It has a rather high energy density, characterized by the greater presence of lipids which, as it is known, provide more than double the calories compared to carbohydrates. These are mainly unsaturated and have a fair concentration of essential polyunsaturates (mainly omega 6).
Thanks to the excellent presence of fibers, the starch of the oat flour is digested and absorbed slowly, to the advantage of the glycemic index of the food (moderate). Moreover, the fibrous portion contains excellent percentages of beta-gucans, beneficial molecules for the treatment of certain metabolic diseases such as hypercholesterolemia (especially LDL) and type 2 diabetes mellitus.
The proteins are abundant (about 50% more than wheat flour) and rich in the amino acid lysine (instead tendentially lacking in cereals).
As far as the vitamin profile is concerned, oats mainly contain vitamin B1 (Thiamine), vitamin PP (Niacin) and vitamin E (α-tocopherol); on the other hand, with regard to mineral salts, excellent concentrations of potassium are observed. , iron, phosphorus and zinc.
