Fruit Juices : An Important Source of Enzymes

Fresh juice deliver another important group of nutrients, know as enzymes. Enzymes are your body’s work force. Acting as catalysts in hundreds of thousands of chemical reactions that take place throughout the body, enzymes are essential for digestion and absorption of food, for conversion of food stuffs into body tissue, and for the production of energy at the cellular level. In fact, enzymes are critical for most of the metabolic activities taking place in your body every second of every day.

Fresh juices are a tremendous source of enzymes. In fact, the “freshness” of juice is one of their key features, because enzymes are destroyed by heat. When you eat cooked foods, whether its meal, grains, fruits, or vegetables, if the food is cooked at temperatures above 114 degrees, the enzymes have been destroyed by the heat. Since fruits and vegetables are juiced raw, the enzymes are still viable when you drink the juice.

Coincidentally, many of the phytochemicals that nutritional researchers are focusing their attention on are either enzymes, or more often, they are substances that help build or activate enzymes that play essential roles in protecting cells from damage.

In addition, fruit and vegetable juices are good sources of the traditional nutrients. Citrus fruits (grapefruit, oranges, etc.) provide healthy portions of vitamin C. Carrot juice contains large quantities of vitamin A, in the form of beta carotene. A number of green juices are a good source of vitamin E. Fruit juices are a good source of essential minerals like iron, copper, potassium, sodium, iodine, and magnesium, which are bound by the plant in a form that is most easily assimilated during digestion.

Plus, since juicing removes the indigestible fiber, these nutrients are available to the body in much larger quantities than if the piece of fruit or vegetable was eaten whole. For example, because many of the nutrients are trapped in the fiber, when you eat a raw carrot, you are only able to assimilate about 1% of the available beta carotene. When a carrot is juiced, removing the fiber, nearly 100% of the beta carotene can be assimilated.

Finally, fruits and vegetables provide one more substance that is absolutely essential for good health – water. More than 65% of most of the cells in the human body are made of water, and in some tissues, for example the brain, the cells can be made up of as much as 80% water. Water is absolutely essential for good health, yet most people don’t consume enough water each day. Plus, many of the fluids we do drink, coffee, tea, soft drinks, alcoholic beverages and artificially flavored drinks each contain substances that require extra water for your body to eliminate. Fruit and vegetable juices are free of these unneeded substances and are full of pure, clean water.
