A red fruit portion to the daily newspaper could be beneficial for cardiovascular health.

English researchers wished to examine more in detail the link between cardiovascular health and consumption of certain antioxydant substances in somewhere .

The latter belong to the family of polyphenols and understand various subclasses, represented differently according to the type of plant. They raised thus the dietary habits of almost 1900 old British women to 18 to 75 years via food questionnaires and measured arterial rigidity as well as the blood pressure of participating, two significant factors in cardiovascular health.

The analysis of the results shows that the regular consumption of two types of flavonoïdes, the flavones and the anthocyanes, are associated with a lower blood pressure and more flexible arteries. The best food sources of anthocyanes are the red fruits and the best sources of flavones are the parsley, thyme, celery and the pepper.

The researchers conclude their results while declaring: “Quantity of anthocyanes associated with these benefit could be reached while consuming one to two red fruit portions per day what is thus important in term of public health to reduce the cardiovascular disease risks.”

Strawberries, raspberries, bilberry, blackberries or blackcurrants are essential allies to fight against ageing The cranberry fights the urinary infections with répétitionVRAI The Indians of America used cranberry to manufacture the famous pemmican but also to treat the urinary, frequent infections during the pregnancy and after the menopause.

Well considering: several studies attest of its effectiveness, including two controlled against placebo. In these two rigorous studies, the risk of infections in 12 months is tiny room of 40% among women having consumed juice or extracts of cranberry compared to the placebo.

There is no difference in effectiveness between juice and capsules of cranberry. The cranberry prevented of the pathogenic bacteria (E. coli) from adhering to the cells of the bladder.

(1) The cherries are useful in the goutteVRAI This remedy of woman is about to being checked. It is in any case the conclusion of a very recent study during which volunteers consumed approximately 300 G of cherries.

The level of uric acid of plasma lowered 5 hours after, while urinary elimination increased logically. In addition, several inflammatory indices (of which the C-reactive protein) were also downwards.

(2) The bilberries improve the vision nocturneFAUX The bilberries, one reads a little everywhere, were consumed during the Second World War by the pilots of Royal Air Force (RAF) to improve the vision by low visibility. Alas for the legend, the Center of medicine aeronautical of the RAF, questioned by your servant, lunatic that the pilots received bilberries, bilberry jam even of the extracts.

And the 30 scientific studies led since on the subject hardly support this beautiful story: the four last, who are also most rigorous, conclude that the bilberries are without effect on the night vision.

(3) The strawberries are anti-cancerVRAI Like all the fruits, the strawberries bring antioxydants which reduce the damage inflicted by the free radicals to the DNA. But the strawberries make more: they strongly inhibit the formation of cancerogenic compounds called nitrosamines which can be formed in the digestive tract when one introduces nitrites or nitrates and proteins (amines).

The nitrosamines, brought in particular by the pork-butcheries, are shown to cause digestive cancers. The strawberries inhibit up to 70% the formation of these cancerogenic agents. A good reason, this summer, to make follow a plate of merguez of a strawberry bowl.

(4) Bilberries, blackberries and raspberries are the best anti-âgeVRAI fruits Kiwi and orange are often quoted like the best sources of antioxydants, but of the researches undertaken to the university Tufts (Boston, Massachusetts) by the team of Ronald Prior, show the superiority of bilberries, blackberries, raspberries and strawberries to reinforce our defenses against the free radicals, responsible for ageing.

The American researchers developed a test baptized ORAC (Radical Oxygen Capacity Absorptance) which measures the antioxydant power of the fruits and other food (see table) in plasma.

The fruits whose scores are highest increase by 10 to 25% the antioxydant power of blood! Moreover, they prevent the memory losses in the old rat and protect the capillaries from these animals against the attacks of oxygen. “On the basis of these result, known as Dr. Prior, I estimate that it would be necessary to get 3,000 to 5,000 units ORAC per day to hope to have a significant impact on the antioxydant capacity of plasma and fabrics. But values ORAC vary so much fruit or from one vegetable to another, which you can eat 7 fruit and vegetables per day and receive only 1,300 units or consume one bilberry bowl and to have more than 3,000 units. ”

Researchers highlighted a new biological way by which the polyphenols contained in bays and the grenades would be degraded in protective molecules for the intestine.

Why it is important There is not any more any doubt that the intestinal microbiote (the billion micro-organisms which lives in the intestines) has major implications in the maintenance of a good health and thus also in the origin of certain diseases.

A new study published in the nature magazine, suggests that certain molecules resulting from the degradation of antioxydant substances, the polyphenols, contained in the red small fruits and the grenades, by the bacteria of the microbiote would have various beneficial effects on intestinal health.

To also see: How the intestinal microbiote protects us (subscribed) the study In this study, the researchers wanted to evaluate the impact of a molecule resulting from the degradation of polyphenols of certain fruits by the intestinal flora, Urolithine A (Uro A): In vitro, on cultures of human intestinal cells. In vivo, on mice presenting of the intestinal diseases.

The idea to evaluate the impact of this molecule and its counterparts on the health of the digestive system did not come from nowhere. Indeed, previous epidemiological studies highlighted a correlation between consumption of fruits (mainly bays and grenades) and intestinal good health.

The scientists thus wanted to know if a biological mechanism could explain this association. Here results of the researchers: Uro A has anti-inflammatory drugs effects (by decreasing the level of the méditateurs of the ignition), antioxydants (by activating a way of protection biological against the oxydative stress) and anti-age on the internal wall of the intestines.

Use A makes it possible to reduce the intestinal permeability while acting on the tight junctions which connect the intestinal epithelial cells (in the mouse).

At the man, Uro A could thus have clinical implications in the inflammatory diseases of the intestine, the cirrhoses of the liver, the diseases neurological and cancers of the colon only thanks to its action on the intestine.

This study informs us about the probable mechanisms by which the bays improve intestinal health. However, if one can suppose that Uro A will have beneficial effects on the base of the experiments led in laboratory, it will be necessary to expect clinical trials to be able to ensure itself some.

Use A in the intestine are sufficient to directly obtain the effects noted here by the researchers with Uro A, these fruits remain invaluable allied health.

When they are of season, you can easily find them on the stalls, and they freeze easily. Urolithine A is also directly in the form of food supplement (not to be taken without preliminary medical opinion).
