Uncovered new merits of unrefined cereals
If you think about the damage he has caused for a long time in China Beri-beri , neuropathy caused by lack of vitamin B1 , due to the fact that only the wealthy would use eating polished rice (= Glazing removal of the cuticle covering of the grain), thereby depriving him of most of micronutrients, one can understand why the food preserves full health at various levels.
There are many substances in plants that are brought together in one little known group that goes by the name of " associated with dietary factors, but they have very important functions both in the absorption of that in ' use of nutrients. Many of these substances are lost in the refining process, as well as in cooking processes.
logical consequence is the invitation to use whole foods as much as possible in daily, from infancy !
"Bread and pasta are also used to reduce the pressure

MILAN - We know that whole grains can help control weight because they give a greater sense of satiety, which can be and are useful in the prevention of diabetes and cardiovascular disease and even to protect us from some cancers, but now a study controlled clinical tells us that whole grains can also reduce the pressure. In the study, published by ' American Journal of Clinical Nutrition, researchers from England, University of Aberdeen, went to check the effects on blood pressure of adding whole grains to your diet. The study involved more than 200 healthy men and women, middle-aged, who, after an initial period Diet "refined", were divided into three groups: one continued with this type of power, the other two have replaced three servings of refined grains with equal amounts of whole grains (wheat-only, in a group of wheat and oats, in the other).
To be clear: two servings of grains a day equivalent, for example, to 70-80 grams of bread, and 30-40 grams of breakfast cereals equivalent to one serving). After three months it was observed that in groups on a diet "integral" systolic blood pressure (the "maximum") decreased by 5.6 mmHg compared to only registered mmHg less in the other group. If confirmed, these results could translate at the level of the general population, a reduction in the incidence of coronary heart disease and stroke by 15 and 25%. Then, the grains will become the new stronghold of anti-hypertensive diet? Vincent responds Savica, professor of nephrology at the University - Papardo Hospital of Messina, co-author of a recent article on "Diet and Hypertension", published by ' Annual Review of Nutrition. "Given that hypertension is a serious risk factor for kidney disease, which can then lead to dialysis - Savica says - is very likely that the answer is yes. If other studies confirm what we is now seen, the grains may become a "tool" of particular importance to the health of the heart and arteries, which can, on the one hand, to reduce or stabilize blood pressure and, second, to decrease cholesterol levels ( as other studies have already made clear). It is hypothesized that the antihypertensive effect of whole grains can be attributed to all the substances they contain, rather than individual components, although it remains to clarify the mechanisms of action and it remains to understand if some products are better than others . Do not forget, however, that derivatives of cereals are among the main sources of sodium, which reduction remains a cornerstone of the diet for hypertension. "
Cereali integrali a riduzione del sodio a parte , che cosa può servire per abbassare la pressione? «Senz'altro, ridurre il peso quando è in eccesso - chiarisce Savica - e va anche assicurata la presenza di adeguate quantità di potassio (buone fonti sono soprattutto frutta e verdura), che potrebbe contribuire a ridurre i valori pressori con l'aumento dell'eliminazione del sodio. Attenzione, però: chi decide di testa propria di sostituire il sale da cucina con quello "della farmacia" più povero di sodio, forse non sa che la notevole ricchezza di potassio di questo prodotto può essere dannosa per le persone che soffrono di malattie renali (magari senza saperlo) e tanto more for people on dialysis because it exposes them to serious cardiac arrhythmias. "Even football, such as milk and derivatives with low-fat - Savica continues - and omega-3 fatty acids, which is rich in oily fish, could be used. As well as moderate consumption of tea, for its content of flavonoids which positively affect the functioning of endothelial cells (lining the inner surface of the arteries), improving control of blood pressure. " And chocolate may help as they say? "Probably yes, at least in the case of dark chocolate, rich in flavonoids. These positive effects are already manifest with small amounts: around 6 grams a day. " "With regard to alcohol, while small amounts of red wine may have a positive effect because of vasodilating action of phenols - Savica ends - should be avoided the abuse, which increases the risk of hypertension as well as stroke."
