Juices are the perfect fast food for today’s eat-on-the-run lifestyle. They contain all the goodness of the whole product in a condensed form. For example, a pound of carrots can be a significant source of calcium and protein, but those ten carrots may be more than you’re willing to eat at a single meal. Juicing concentrates that one pound into a single glass of easy to drink juice. These nutrients are quickly assimilated since the body does not have to separate out of the fibre.
Fibre is extremely important to the human body, and your diet should contain at least 30 grams of dietary fibre a day. This is easily accomplished by substituting whole grains for refined cereals and flour, legumes for red meat, fruits for sweet desserts, and adding salads on a daily basis. Fruit and vegetable juices should not be used as a substitute for whole produce, but as supplements to them.
Not only are fruit and vegetable juices your best convenience foods, they provide thousands of substances, some of which have well-known functions, and some whose roles in the human body are not yet understood or recognised. Current wisdom recognises three roles that fruit and vegetables play in the human body:
Fruits and vegetables provide nutrients essential for growth and renewal
Fruits and some vegetables contain substantial amounts of carbohydrates which supply most of the energy we use to live and perform work, they also have generous amounts of vitamins. Vitamins regulate metabolism and help in the conversion of the fats and carbohydrates into energy. Fruits and vegetables contain minerals that are necessary for the nerve and muscle function and are the building material for some body tissue.
Fruits and vegetables have a protective effect
Fruits and vegetables can protect the body from such major diseases as cancer and heart disease. Some are high in substances called anti-oxidants, such as beta carotene, Vitamins C and E and selenium, which are nutrients that protect cell membranes from the damage of free radicals. Some are rich in other anti-cancer compounds, this is especially true of the cruciferous family to which the cabbage belongs.
Fruits and vegetables have a medicinal effect
Fruits and vegetables can be your best non-prescription drugs. For example, blueberries are an effective anti-diarrheal agent, and ginger is as effective as well-promoted motion-sickness drug, and new studies show that it also relieves nausea and stomach discomfort caused by pregnancy.
