Why sugar makes cancer tumors aggressive

Does the thought of fighting for your life against a disease that grows inside your body, taking over your organs and spreading day by day keep you up at night?

Or, maybe you’ve already battled cancer and just want to know how to prevent it from ever coming back so that you never have to go through the surgeries, chemotherapy and radiation again.

If so, the results of a new study could hold the answer you’re looking for.

A nine-year joint research project has led to a crucial breakthrough in cancer research. Scientists have now clarified how the Warburg effect, a phenomenon in which cancer cells rapidly break down sugars, stimulates tumor growth.

Not only does this discovery provide evidence for a positive correlation between sugar and cancer, which may have far-reaching impacts on tailor-made diets for cancer patients but also gives us clues to how we can use diet to prevent cancer growth in the first place.

The sugar-cancer connection

The Warburg effect, or the observation that tumors convert significantly higher amounts of sugar into lactate compared to healthy tissues, is one of the most prominent features of cancer cells. It’s even been used to detect brain tumors.

To observe and analyze this phenomenon, the researchers used a yeast model to examine the connection between activity of Ras proteins (compounds found in tumor cells) and sugar metabolism.

And, what they found will make you want to go sugar-free.

According to the scientists, not only did sugar awaken and stimulate cancer cells, it also made them more aggressive.

As Professor Johan Thevelein, one of the project leaders, put it, “Our research reveals how the hyperactive sugar consumption of cancerous cells leads to a vicious cycle of continued stimulation of cancer development and growth. Thus, it is able to explain the correlation between the strength of the Warburg effect and tumor aggressiveness. This link between sugar and cancer has sweeping consequences.”

Cutting out the sugar

Clearly, if sugar wakes up cancer cells and makes them grow more quickly and aggressively, cutting out sugar could help you to live healthier and possibly even cancer-free for life.

So, how do you do that?

One of the best options for eliminating sugar from your life is to follow the ketogenic or keto diet. The ketogenic diet (keto) is a low-carb, high-fat diet. It lowers blood sugar and insulin levels, and shifts the body’s metabolism away from carbs and towards fat and ketones.

Because you’re cutting out carbs, you get very little sugar in your diet to stimulate and feed those cancer cells. In fact, the diet is currently being used to treat several types of cancer and slow tumor growth.

To do the keto diet, you need to avoid:

  • Sugars – Sodas, cakes, ice cream candy and more are foods to stay away from.
  • Fruit – On the keto diet even fruit sugars are restricted.
  • Grains and starches – Bread, pasta, rice and potatoes are all no no’s on this diet.
  • Beans – Beans and legumes contain starches that are converted to sugar so they should be avoided.
  • Alcohol – Alcohol contains carbs and sugars so just say no.
  • Sugary Condiments – Many sauces contain sugar, like ketchup and barbeque sauce, so be sure to check the label before you add it to your food.
  • Diet Foods – Many diet products are high in carbs and sugar alcohols so stay away from them.

Instead, you’ll eat healthy proteins, like fish, chicken and lean beef, eggs, butter, cream, nuts and seeds, and healthy oils, like coconut, avocado and extra virgin olive oil. And of course, don’t forget the low-carb veggies, including most green veggies, tomatoes, onions and peppers and avocadoes for a dose of good fats.

Your diet should be 75 percent fat, 20 percent protein and only 5 percent carbs. You can drink water, tea or coffee and can use a natural, sugar-free sweetener, like stevia.

Use the tips above to cut the sugar-cancer connection by going sugar-free with the keto diet and stop worrying about the Big C.
