A 56-Year-Old Woman Di.es from Can.cer Despite Eating Steamed Food Every Day: Doctor Warns, “Even Healthy Foods Can Become Harmful”

Doctors warn that certain eating habits may quietly increase cancer risk over time.

For many people, steamed food is considered one of the healthiest cooking methods. However, doctors say that even healthy foods can become harmful if consumed the wrong way or combined with risky eating habits over a long period.

According to the report, Ms. Li from Fuzhou, China, was well known among her neighbors for maintaining what appeared to be a healthy lifestyle. After retiring at the age of 51, she became especially devoted to healthy eating. She rarely ate fried food, preferred steamed dishes, and prepared fresh meals every day. Friends and family believed she would enjoy a long and healthy life.

However, tragedy struck unexpectedly.

For several months, Ms. Li experienced persistent mouth ulcers that refused to heal. Although she used medication, the ulcers repeatedly returned and gradually became more severe. When the pain became unbearable, she finally visited a hospital, where doctors diagnosed her with advanced oral cancer that had already spread to nearby tissues.

Only three months after receiving the diagnosis, she passed away despite undergoing treatment.

The case surprised many people because she had always been known for eating "healthy" food. After reviewing her daily habits, doctors pointed to several long-term practices that may have contributed to increasing her risk of oral cancer.

1. Eating Extremely Hot Steamed Food

Doctors noted that Ms. Li enjoyed eating steamed buns while they were still piping hot. She often ate them immediately after they came out of the steamer.

Medical experts warn that repeatedly consuming foods hotter than 60°C (140°F) can damage the lining of the mouth and esophagus. The World Health Organization (WHO) has previously classified the habitual consumption of very hot beverages and foods as a factor that may increase the risk of certain cancers because repeated heat injury can cause chronic inflammation and cellular damage.

2. Frequently Eating Pickled Foods

To make steamed buns more flavorful, Ms. Li often paired them with pickled vegetables, salted cabbage, or preserved meat.

Doctors explained that although rinsing or heating pickled foods may reduce some salt content, it cannot completely eliminate harmful substances. Pickled foods are often high in sodium and may contain nitrites, which can react with compounds in the digestive system to form nitrosamines—chemicals that have been linked to an increased risk of cancer. Eating these foods frequently, especially on an empty stomach, may further increase the risk.

3. Failing to Discard Moldy Food

Family members said Ms. Li was careful not to waste food. When grains or cereals became slightly moldy, she often removed the visibly spoiled portions and continued eating the rest.

Doctors warned that this habit can be extremely dangerous. Mold may produce aflatoxins, toxic substances that are highly resistant to heat. Simply washing or cooking moldy food cannot completely destroy these toxins. Once consumed, aflatoxins may damage cells and have been associated with an increased risk of several types of cancer.

Medical experts emphasize that no single food alone causes cancer. Instead, cancer usually develops through a combination of genetic factors, environmental influences, and long-term lifestyle habits. Nevertheless, avoiding extremely hot foods, limiting pickled foods, discarding moldy ingredients immediately, and maintaining regular health checkups can help reduce potential health risks.
