Any balanced diet includes vegetables and fruits. It is believed that you should prefer fresh and not frozen food, as when frozen they lose their useful properties. But the American scientists have found that frozen fruits and vegetables contain more vitamins and minerals than those that are sold in stores as fresh. After five days storage in the fridge, vegetables lose their frozen counterparts the amount of vitamin A.

Researchers from the University of California more careful in the estimates. Some vegetables (broccoli, carrots, corn, beans) do freeze retain certain nutrients, e.g., Riboflavin (aka vitamin B2) is involved in the formation of red blood cells and ascorbic acid required for the normal formation of connective and bone tissue. But the content of beta-carotene (provitamin of vitamin A) found in many foods freeze is significantly reduced.

The juice is an important part of healthy nutrition, as they contain many useful substances and vitamins. There are even some types of diets in which you a few days to drinking only juices, exclude from the diet all the rest.

Researchers are advised to drink fruit juices in small quantities and only after a meal. But this is fraught with unpleasant consequences. As found by Australian scientists, regular consumption of fruit juice significantly increases the Central aortic systolic pressure, which increases the risk of developing cardiovascular disease.
