I definitely recommend against the prolonged daily intake of straight carrot or beet juice. Both carrots and beets are extremely hybridized foods. They may heal one to a certain degree (because they are nutrient-rich raw plant foods), but once you reach a certain level of attunement, the body can begin to react to the sugar. If used to sweeten juices, consider using no more than one carrot or one beet per 1 quart of juice. Cucumber softens the bitterness of vegetables and is an excellent base for vegetable juices.
I also recommend that we avoid seedless fruits such as: bananas, seedless grapes, seedless oranges, pineapple, seedless watermelon, etc. These foods, are bread for certain genetics and then weakling, sugary plantings and cuttings are spread to gardens and farms everywhere. These weak strains are essentially artificial and loaded with hybrid sugar.
Hybrid sugar, like refined sugar, can overstimulate the endocrine system, unless it is mitigated with fats, green-leafed vegetables or high-protein foods (such as spirulina, blue-green algae, maca or bee pollen) to "lessen the shock". The glands sense the body is loaded with food, but hybrid foods (especially commercial fruits and sugary root vegetables) are fairly empty of trace nutrients and the body signals more hunger, which leads to an overeating of hybrid sweet fruit.
A diet heavy in hybridized sweet fruit can lead to constipation, especially if the individual is not highly active. Because excess sugar spills off into the urine, excessive urination can occur when the sugar is not being immediately utilized (due to a lack of activity). Excessive urination leads to dehydration and a potassium overdose, behind which follows constipation. This process is accelerated if nuts are included in the diet (without greens) as nuts are more difficult to digest and slow the digestive system. If this process continues unabated, a minor diabetic condition will occur as the body is constantly urinating to spill off excess sugar.
Too much sugar in the blood triggers the release of alkaline minerals, such as calcium, from the bones and tissues to buffer sugar's acidifying effects.
Excessive intake of refined and even hybridized sugar can cause a hyperinsulinization of the blood. This can lead to drowsiness and fatigue.
Cooked grains and cooked hybrid vegetables (beets, carrots, corn, potatoes) cause a greater sugar rush into the bloodstream than fruit!
