Vitamin C and Sugar - We know that cancer cells only eat sugar. They are sugar piggies. For instance, PET scans for cancer detection where radio-ionized frequencies are applied to sugar molecules and then this solution is injected by IV to the patient. The sugar molecules go directly to cancer cells, called "self-direction", the nuked sugar molecules light up the cancer cells, and a photo is taken of the lit up cancer tumors. In Europe, a solution of sugar and vitamin C is injected by IV, and self-directed to the cancer cells. When the Vitamin C enters the cancer cell it gives off hydrogen peroxide. Hydrogen peroxide is very toxic to cancer cells. They die, leaving healthy cells alone.

Abstract
PURPOSE OF REVIEW:
Cancer cell metabolism is characterized by high rates of glucose uptake and anaerobic glycolysis. Sugar consumption has increased dramatically in the industrialized world, with refined fructose intake skyrocketing upwards in the USA over the past 30 years. Fructose provides an alternative carbon source for glycolysis, entering downstream of glucose and bypassing two key rate-limiting steps. Considering that glycolysis is the major pathway which fuels cancer growth, this review will focus on regulation and flux of glucose versus fructose through this pathway, and consider whether epidemiologic and experimental data support a mechanism whereby fructose might potentiate cancer growth in transformed cells.(Figure is included in full-text article.)

RECENT FINDINGS:
]Fructose intake is associated with increased risk of pancreatic and small intestinal cancers, and possibly others. Fructose promotes flux through the pentose phosphate, which enhances protein synthesis and may indirectly increase tumor growth. Fructose treatment is associated with more aggressive cancer behavior and may promote metastasis.
SUMMARY:
Whereas glucose favors overall growth kinetics, fructose enhances protein synthesis and appears to promote a more aggressive cancer phenotype. Fructose has become ubiquitous in our food supply, with the highest consumers being teens and young adults. Therefore, understanding the potential health consequences of fructose and its role in chronic disease development is of critical importance.
