Effects and mechanisms of fruit and vegetable juices<br />
On cardiovascular diseases<br />
Many studies have demonstrated that some natural products have high antioxidant activity, as<br />
Vegetables, fruits, cereals, mushrooms, micro algae, wild flowers and herbs, which might be used to prevent<br />
diseases.<br />
There is a large amount of clinical evidence showing a reduction in the risk of many diseases to live a healthy life by<br />
eating fruit or vegetable juices, some of these diseases are cancer, neurodegenerative diseases and cardiovascular<br />
diseases. Cardiovascular disease includes disorders of blood vessels and the heart, such as hypertension,<br />
cerebrovascular disease, peripheral arterial disease, coronary heart disease and many others. Cardiovascular<br />
diseases are one of the main not communicable causes of deaths, usually associated with metabolic disorders,<br />
including diabetes and obesity.<br />
Mechanisms of action of juice in cardiovascular diseases<br />
Through clinical studies, it was confirmed that after eating rich antioxidant juices daily, the oxidation of lipids in<br />
plasma decreased significantly (- 29%), while the antioxidant capacity of the plasma increased (+ 115%) after<br />
the intervention. In addition some diet managed to reduce tissue inflammation process, which if persistent is<br />
related to most chronic diseases, there<strong>for</strong>e, could reduce the risk of cardiovascular disease. In Li et al. study, he<br />
assessed the effect of lycopene present in tomato juice on the protein-1 tactical chemo of monocytes (MCP-1) and<br />
the result showed that MCP-1 dropped sharply after the consumption of the juice.<br />
Possible adverse effects of juices<br />
It should be noted that the caloric content of the juice could complicate the health. Some commercial juices of fruit<br />
/ vegetables contain too much sugar, which can increase the risk of increasing weight and diabetes. Regular<br />
consumption of beverages sweetened with sugar related to type 2 diabetes, and sweetened fruit juice was not a<br />
healthy alternative to prevent diabetes.<br />
In summary the effects of fruits and vegetables juices in cardiovascular diseases, is positive because they could<br />
prevent the increase of blood pressure and lipid levels improve. The main underlying mechanisms of<br />
cardiovascular protection include antioxidant effects, the improvement in endothelial function, inhibition of<br />
platelet aggregation, the anti-inflammation and the prevention of hiperhomocisteinemia.<br />
It is always important to consult with a professional to assess the issue.<br />
