Breakthrough Study: Galactose and the Warburg Effect

In 1931 Otto Warburg won a Nobel Prize for his research into tumours, and cancer cells. He discovered that healthy cells and cancer cells ‘breathe and eat’ (metabolise) very differently. Ever since his ground-breaking discovery over 90 years ago, scientists have been researching these critical metabolic differences. Thousands of scientific papers have been published to understand why, and how, cancer cells rewire their metabolism.

In this article, we review the latest research, and life-saving implications, of the role different sugars play in this metabolic mystery. For the first time, there is very clear evidence that specific types of dietary sugar are implicated in either feeding or starving, the spread of cancer. Could galactose pave the way to a safer sweet tooth?

Each of your 32 trillion cells has to take in fuel, then turn it into energy. Carbohydrates (sugars) and fats are the most common energy sources, but other substances, like amino acids, can also be used to make this ‘bioelectricity’. Your body uses an energy currency (like £’s or $’s) called ATP, which it makes from ADP. You don’t need to know how it’s made, but you do need to know we make an incredible 70kg of this critical energy currency every day, and all of it is spent!

We only store enough ATP for about 7-seconds of survival before the ‘power’ goes out. Fortunately, our cells have evolved to use different fuel sources, and multiple pathways, to make bioelectrical energy from our food fuel. Phew! That’s a relief. We don’t ‘power-down’ due to a lack of ATP; even when we don’t get enough oxygen (like when we are running) our cells find ways to keep making energy.

Cancer cells can use fat for fuel but choose to use simple sugars, specifically glucose, as there are hidden benefits. Researchers from the Cancer Institute of Xuzhou Medical University just published a remarkable study in the prestigious Nature Journal: Cell Death and Disease (impact score 8.79) exploring the mechanisms driving this metabolic manipulation, and the implications are incredible.

There are seven main theories that explain why cancer cells prefer glucose:

1. Speed: Glucose provides the quickest way to make energy, so they can grow and spread as fast as possible.
2. Competition: They take the most accessible fuel source, depriving healthy cells and cancer-fighting immune cells.
3. Biosynthesis: After using glucose for fuel, the carbon is transformed into building blocks (e.g. nucleotides).
4. Environment: Anaerobic glycolysis acidifies tissues, weakening the connections between healthy cells.
5. Signalling: The ratio of metabolic by-products (NAD to NADH specifically) creates growth-enhancing signals.
6. Epigenetics: Reactive Oxygen Species (ROS) drive genetic ‘tagging’ (Acetylation), making DNA easier to copy.
7. All of the Above: Most likely, all of these reasons come into play, depending on cancer and tissue type.

• Malignant tumours (cancers that spread) are enhanced by anaerobic glycolysis (glucose without oxygen).
• The rate of anaerobic glycolysis is directly proportional to the rate of cancer metastasis (cancer spreading).
• The enzyme transketolase (TKT) is involved in anaerobic glycolysis and is associated with tumour growth.
• The ‘family’ of TKT enzymes are also associated with lung, liver, breast, pancreatic, and cervical cancers.
• Increased TKT (in tissue samples or DNA expression) was associated with worse cancer outcomes.
• TKT expression was much higher inside tumours than in surrounding tissues and control samples.
• TKT was strongly associated with cell growth, tumour size and cancer migration (metastasis).

Combined with the latest results, existing studies show a strong correlation between TKT and cancer growth. Patients with colon cancer are nearly twice as likely to survive (at 36-months) if they have a low TKT expression. TKT expression is so closely linked to cancer outcomes that it can be used as an indicator of survival likelihood.

Now that we know the how and why of cancer’s metabolic madness, we can reveal the practical implications. How can we use this research to prevent, diagnose, or even treat cancer? The results are astounding, and you can benefit from them immediately. This research went much deeper than just looking for positive correlations, they managed to turn off the effect. They managed to take away the metabolic advantage cancer cells create. Again, using three different methods (they were very thorough!), they decelerated tumour growth, reduced the tumour’s ability to spread, slowed the growth of blood vessels (angiogenesis) and helped healthy cells remain stuck together (preventing cancer from invading new areas). So, what were the methods they used for such an impressive shift?

• Firstly, they used genetic engineering to create cells and rats without the TKK enzyme.
• Secondly, they used selective poisons which directly inhibited the TKK enzyme.
• Thirdly, they used a different type of sugar, they used galactose.

The first and second options aren’t practical ways in which we can bypass cancer’s metabolic optimisation for growth and invasion. But the third one is. It is a simple and effective way to get the upper hand by reducing the metabolic advantage cancer cells engineer. The sweet solution is simple; switch to a safer sugar.

“We used galactose which induced cells to survive on ATP provided by mitochondrial respiration.” Transketolase promotes colorectal cancer metastasis through regulating AKT phosphorylation Journal of Cell Death and Disease – Feb 2022

World-renowned scientist Dr Johannes Coy has been developing safer sugars for decades.[v] His extensive research into the TKTL1 gene, and other metabolic markers for cancer, drives his mission to educate the public about diet, disease, and sugar specifically. Galactose is a simple sugar (like glucose) but it is metabolised very differently. It essentially ‘forces’ the cell powerhouses (mitochondria) to use fat and oxygen to make fuel. This metabolic difference is immense. The taste is similar, but the body responds completely differently. Galactose can even fuel the brain, like glucose, but it doesn’t let cancer cells hijack your metabolism. Not only is galactose better for you metabolically, but it’s also got fewer calories than sugar and even encourages the body to mobilise and burn fat; making it excellent for weight loss, diabetes and physical endurance. Dr Coy also went a step further, blending it with another metabolically safer sugar, tagatose, to create a sugar alternative that tastes delicious and is actually good for your body
