Nuts better than olive oil in the prevention of arterial
A study of new medical Spanish that eating walnuts may be the best to protect the arteries of the olive oil. Spanish researchers found that after a fatty meal have remained high in fat arteries who ate nuts more than a measure of the softness and flexibility. Study was conducted by a research team from the clinic clinical study of fat in Barcelona, Spain, led by Dr.. Emilio Ros, and published their results in the next issue of the magazine "American College of Cardiology", or (jacc), and presented Nijsmdhikal Net. D studied. Ross and colleagues 24 cases of adults and non-smoking normal weight and have normal blood pressure. Although half of the participants have high levels of cholesterol, were not taking any medications or treatments.
Coconut, olive oilBefore the start of the experiment and during the two weeks, participants observed a system of food the Mediterranean region, strictly, a diet low in fat and meat, but its content is high in fiber, fruits and vegetables.
Participants then discussed the meals of cold meat sandwiches (salami) and cheese on white bread with a limited amount of milk fat Alrayb.Half of the participants and added to the meal the amount of walnuts by an eight-nuts, while he other half of the amount of olive oil by five teaspoons.
Week after the start of the experiment, continued to provide the same high-fat meal for the participants with the switch-ons, half of the participants who ate nuts were transferred to the olive oil, and the other half were transferred from the olive oil to the nuts.
Flexibility of blood vesselsAnd tests using ultrasound, the researchers were able to preview the arteries, and found that olive oil and nuts may cut the emergence of inflammation and oxidation after the high-fat diets, but eating walnuts maintained flexibility of blood vessels, which does not have its olive oil.
D attribute. Ross, director of the clinic fat, the beneficial effects of coconut to the acid alpha - linolenic located in it, which is similar to the omega-3 fatty acids found in fish.
The attention of Ross that many experts, including the American Heart Association, recommend that the public eat two meals, at least weekly, of fish rich in fat and omega-3 fatty acids, because it raises levels of HDL cholesterol in the blood and is useful for health, which helps to free the arteries of deposits bad cholesterol.
However, it is also noted that fish rich in fat are not always available to the consumer, and not easy to obtain and consume as walnuts.
Multiple factorsHas d. Robert Vogel, professor of medicine at the University of Maryland, to review the study Spanish commissioned by the American College of Cardiology, found that fat nut protective disrupt some of the harmful effects of food containing high fat saturation, while the fat, neutral - such as olive oil - not a lot of these preventive capacity .
Vogel said the study Spanish indicates that those who eat the so-called "Mediterranean diet", thinking that olive oil provides health benefits primarily for the heart, they will see that this is not true, and that other factors such as food relatively rich nuts are better able to protect heart desired. Olive oil is not the key protective factor in the diet of the Mediterranean region.
Underlines the need for further research and testing to ascertain the role of preventive useful for walnuts, and are influenced by heating, cooking, or that it is better to be eaten raw nuts.
