New Study Shows Dietary Changes Can Shrink Tumors

Quentin Oliver Lee, 34, died of colon cancer on December 1, 2022. A Broadway actor and singer, Lee announced he was diagnosed with stage 4 colon cancer just six months ago.

Lee’s devastating and untimely death comes in the wake of the bad news: Colorectal cancer rates are rising in the United States and other countries of the industrialized world, especially among young people, according to a recent American Cancer Society. statement.

Colon cancer in the United States accounted for 7.9 percent of new cancer cases and 8.6 percent of deaths in 2022. According to the National Cancer Institute. An estimated 52,580 people will die from colon cancer this year.

The good news is that we have a growing body of evidence, both from high-quality scientific research and from patient personal experience, that shows that diet and lifestyle changes can effectively stop cancerous cells in their path.

One of the most recent and promising of these studies was conducted on mice by a team of ten researchers at the University of Michigan.

Study“Dysregulated Amino Acid Sensing Drives Colorectal Cancer Growth and Metabolic Reprogramming to Chemoresistance,” was published in the journal Gastroenterology in November. For this study, scientists investigated how low-protein diets affect colon cancer cell growth.

More specifically, they studied something called mTORC1 activation in animal and human tissue.

What is mTORC1?

mTORC1 are molecules that are sensitive to nutrients and are thought to become hyperactive when people have cancer. These molecules are involved in 70 percent of human cancers, including colorectal cancers.

Other animal studies have shown that inhibiting mTORC1 also inhibits tumor growth. Some drugs that interfere with mTORC1 signaling pathways have also been found to inhibit tumor growth. However, pharmaceuticals that block this cancer are in “limited use.” Medical News Todayboth because of their adverse immunosuppressive side effects and because of the return of tumors after the drugs are discontinued.

It is also a 2015 study showed that restricting protein intake reduced mTORC1 tumors in mice.

This study, by an international team of researchers from the United States and Italy, noted that “reduced dietary protein intake and intermittent fasting (IF) are both linked to healthy longevity in rodents and are effective in inhibiting cancer growth.” The scientists hypothesized that the cause may be “downregulation” of mTORC1 pathways. While the study focused on breast cancer, the authors concluded that their study suggests that protein restriction “may represent a highly translatable option for the treatment of not only cancer but also other age-related diseases.”

Restricting Protein to Prevent Colon Cancer

For this new research, the scientists found that mTORC1 activation was higher in the presence of amino acids. Next, they examined how colon cancer tumors in mice would respond to a two-week protein-restricted diet followed by four weeks of chemotherapy.

Mice are usually fed a 21 percent protein diet. For this experiment, the researchers fed the mice diets containing only four percent protein.

They discovered what they expected: Mice fed low-protein diets had less mTORC1 activation and less tumor growth than controls.

More specifically, reducing the intake of two amino acids (leucine and cystine) seemed to signal to disable mTORC1 from a nutritional standpoint.

This effect is not just in mice. When the scientists tested human colon cancer, they found that samples with the most genetic markers of mTORC1 tended to have the worst results.

Hungry Cancer

Cancer cells grow exponentially. They need nutrients to reproduce so quickly. Some of the nutrients they need are synthesized inside cells, but other nutrients — including amino acids — come from a person’s diet.

The reason a low-protein diet appears to be effective at limiting tumor growth in the colon is because depriving colon cancer cells of protein essentially starves them.

“Feeding or starving cancer cells … is complex,” Jeffrey Nelson, MD, surgical director of the Center for Inflammatory Bowel and Colorectal Diseases at Mercy Medical Center in Baltimore, Maryland, told Medical News Today. “But this research shows that deprivation of certain amino acids affects the mTORC1 pathways that lead to cell death.”

China Study

A Cornell-trained biochemist and director of the Center for Nutrition Studies, Dr. T. Colin Campbell has published more than 350 research papers, most of them. peer-reviewed. In his landmark book, “The China Study,” first published in 2005, Campbell and his medical doctor son Thomas explored why the protein fad diets so popular in the 1970s (and beyond) were unsuitable for human health. health.

Instead, the research presented in the book is based in part on a few longitudinal nutrition studies From 1983 to 1990, large numbers of adults and their families were executed in China and Taiwan, mostly plant-based dietOne that was lower in protein and higher in dietary fiber and whole foods appeared to lead to the best health outcomes. A 55 minute movie“The China Study Documentary” is also available on the YouTube channel of the T. Colin Campbell Center for Nutrition Research.

People living in China where the regular diet was a diet with a lower amount of animal protein were less likely to develop diabetes, cancer and heart disease.

Chris Beats Cancer

Chris Wark was diagnosed with Stage III colon cancer when he was just 26 years old. After undergoing colon surgery to remove the cancer, she made the controversial decision not to follow her traditional doctors’ advice to undergo chemotherapy. Instead, Wark turned to nutrition and alternative healing, a journey he documented in his 2018 bestseller Chris Beats Cancer.

As detailed in the book, Wark’s cousin Jeff was also diagnosed with colon cancer: Stage IV. Jeff was told that cancer is incurable. He could live up to two years with chemotherapy. According to the doctors, he would have died within six months without it. Although Jeff’s mother encouraged him to talk to his cousin, Jeff told his mother that he and Chris were very different people and “doesn’t believe in fads or self-help books.”

Although surgery to remove the cancer seemed successful, chemotherapy left him sick and depressed. Tumors began to grow in his liver and abdomen. Jeff died three months after he was diagnosed. He was 49 years old.

But the idea of ​​rehabilitating himself by poisoning himself using chemotherapy made no sense to Wark. Instead, she adopted an organic raw whole-food diet, found a holistic oncologist willing to treat herself with a natural and non-toxic approach, and also sought alternative treatments, including counseling, acupuncture, and chiropractic care. Nearly two decades later, Wark is cancer-free, father of two, author of three best-selling books, and a popular podcast host.

“I have eliminated everything in my life that could have contributed to me. [cancer]” told the Epoch Times.

“Cancer cells are not alien invaders,” Wark reminds his readers. “Cancer cells are your cells with your DNA. Cancer isn’t just in you, it’s you. The presence of cancerous tumors is the result of a malfunction in the normal functioning of your body… Cancer is a condition created by the body and can be resolved by the body if given proper nutrition and care.”

University of Michigan study finds diet and lifestyle changes — in addition to limiting protein intake calorie restriction— may help inhibit the growth of cancer and may also make chemotherapy more effective.

Whether you choose a traditional treatment plan or an alternative treatment plan, it seems to limit your exposure to known carcinogens (including these) to stop colon cancer from multiplying in your body. glyphosateSome volatile organic compoundsand specific pharmaceutical drugs and injections), along with eating a lower protein diet will help you restore your health.
