The Sweet Trap: Feeding the Cancer Cells

A cup of boba tea, a slice of cake, or even a bowl of pho with a sugary broth… These treats satisfy our taste buds, but little do we know that sugar—especially refined sugar—is the preferred fuel for cancer cells.

According to Dr. Tran Van Phuc (Xanh Pon General Hospital) in an article on VnExpress, cancer cells have the ability to “consume sugar” up to 10-12 times more than normal cells. “Therefore, a diet high in sugar can cause tumors to grow faster,” he says.

Additionally, when the body consumes too much sugar, the pancreas has to work continuously to produce insulin—a growth-stimulating hormone that creates favorable conditions for abnormal cell growth. That’s why people with type 2 diabetes have a higher risk of cancer.

The appealing sweetness of boba tea and cake is the “fuel” of choice for cancer cells.

The Savory Seduction: Grease May Taste Good, but It’s Harming Your Body

The sensation of rich, fatty foods can make dishes more appealing—from fried chicken and fried spring rolls to french fries and cheese cakes. But according to Associate Professor Dr. Nguyen Duy Thinh (Institute of Biotechnology and Food Technology, Hanoi University of Science and Technology), trans fat in fried foods at high temperatures is a “culprit” in promoting breast, colorectal, and liver cancers.

Sharing on ZingNews, he said: “When oil is reused for frying multiple times, the fat molecules change and produce oxidizing agents that cause gene mutations—the root of cancer.”

In addition, saturated fat in red meat and processed foods can cause chronic inflammation—one of the foundational factors leading to cancer. The more fried and salty foods you eat, the higher the risk, especially for young people who have a habit of eating fast food and drinking sugary beverages.

Deep-fried and salty foods may taste delicious, but they can silently harm your health.

The Silent Killer in Your Diet: Salt

Fish sauce, pickled vegetables, bacon, sausages… These familiar foods contain salt levels far beyond recommended guidelines. Many people mistakenly believe that only hypertension is related to salt intake, but in fact, stomach cancer is a more serious potential consequence.

According to Vietnamnet, the World Health Organization (WHO) warns that there are more than 1 million new cases of stomach cancer each year, and salt and salted foods are a significant risk factor. Salt damages the stomach lining, creating favorable conditions for the development of Helicobacter pylori bacteria—the main cause of stomach cancer.

Vietnam is one of the countries with salt consumption twice the recommended level. A 2023 survey by the National Institute of Nutrition showed that the average Vietnamese person consumes up to 9.4g of salt per day—nearly double the safe limit of 5g.

Indulging Your Taste Buds or Prioritizing Your Health?

We live in an age where the tastier the food, the more dangerous it tends to be. Sweet, savory, and salty flavors not only enhance our meals but also silently erode our health over time.

Ms. Hoang Thi Mai (38 years old, Hanoi) used to drink boba tea almost every day, ate fried foods late at night, and always seasoned her food with extra salt. After discovering precancerous polyps in her stomach, she shared: “I never thought that my daily eating habits could be so harmful. Now, when I see fried doughnuts, I feel afraid.”

While dietary choices are a personal matter, understanding the “nature” of these flavors can help us balance our menus and adopt a preventative lifestyle instead of waiting for treatment.

Expert Advice

  • Gradually reduce sugar intake and replace it with fresh fruit. Avoid sugary drinks.
  • Prioritize steamed and boiled foods. Limit frying or use vegetable oil for single-use only.
  • Reduce salt intake from sauces, pickles, and packaged foods. Estimating the salt content in seasonings is a necessary habit.

“Diet accounts for 30-40% of the risk factors for cancer. Changing our eating habits is the simplest but most effective way to prevent cancer,” said Dr. Truong Hong Son, Director of the Vietnam Institute of Applied Medicine, in an article on Dan Tri.
