Why Avoid Processed Sugar / Carbs?

If you have cancer, or wish to avoid it (and I think that covers 100% of the population, right?), this may interest you.

Many people continue to insist that eating sugar “has nothing to do with cancer”, as one local oncologist assured me years ago. Recently I’ve even seen this stated on the Mayo Clinic website. The lack of understanding of this topic is stunning. It makes my work more difficult, because medical opinion (and quite often it’s just that- opinion) carries a lot of weight in our society…even when it’s unsupported by science or common sense. So what’s the real deal?

1) Does sugar really feed cancer?

Well, we know that cancer requires ten to twenty times more sugar than healthy tissue to produce the same amount of energy. Most cancer cells have significantly more insulin receptors than their healthy counterparts.

It’s important to understand that most healthy cells do not require glucose as a fuel source. Meanwhile, cancer cells need an abundance of glucose (or certain amino acids) in order to thrive. For technical details on this topic I recommend Thomas Seyfried’s book, Cancer as a Metabolic Disease.

Do you want to keep your cancer happy and well-fed? Just eat plenty of processed carbs and refined sugar.

On the flip side, you can selectively starve cancer cells by maintaining a strict ketogenic (very low sugar) diet. This can be a tough diet to stick with, and it isn’t for everyone. But the science is there.

2) Enzymes.

Processed foods don’t contain as many enzymes as raw foods.  Enzymes help your body digest food, absorb nutrients, detoxify, and produce energy.  All of these processes need to be working well to fight cancer naturally.

Enzymes can also help our immune cells gain access to solid tumors through a process historically referred to as “enzymatic de-shielding”. This isn’t breaking news; it’s been known since the mid-1900’s. Your doctor probably doesn’t believe in enzymatic de-shielding. But for what it’s worth, Hans Nieper did. Dr. Nieper was the president of the German Society of Oncology.

3) Processed foods contain preservatives; artificial colors; artificial flavors; flavor enhancers; GMO wheat, soy, and corn; and other things you don’t want to be putting in your body, even on a good day. So it’s not just about carbs and sugar, but also, the other things you’re getting if you eat processed foods.

4) Many of us have a hard time digesting wheat and similar grains effectively.  In some people, this leads to conditions like full-blown celiac disease. In some people, eating wheat may interfere with digestion on a sub-clinical level. William Davis, MD wrote an entire book about this.

5) Processed sugar has been linked to significant decrease in immune function for several hours after consumption. If your immune system is trying to fight cancer, don’t get in its way! If you are taking chemo or using radiation therapy, this becomes especially important since those therapies also suppress the immune system.

6) Opportunity Cost: Every time we fill up on processed garbage, we’re missing an opportunity to fill up on real food. Over time, this depletes our body of energy and nutrients. With each meal, we choose whether to support disease or support health.

7) All that said: if you love a sweet treat from time to time, be kind to yourself! Sometimes we need a break. You might consider using real maple syrup or raw local honey instead of sugar. I recommend trying some of the desserts in the book “Hungry for Health” available at the BeatCancer.org store.
